Chapter 917 Optical Workshop
As he thought about it, two teenagers in overalls came out from the corner and greeted Lin Hanlong and his party.Lin Hanlong waved his hand and asked them to wait for a while.Then he turned and went into his office—a corner of the workshop separated by hollow bricks, and the inner wall was covered with kapok boards for sound insulation—he sometimes had to spend the night in the workshop and do engineering calculations, and needed a relatively quiet environment.

The office consisted of a few desks, a few cabinets, and a row of shelves, filled with documents, oddly shaped pieces of glass, and mechanical parts.There is also a small door inside that leads to his single dormitory.As a patriarch, it was one of the few privileges he enjoyed.

Lin Hanlong walked to his desk and opened the cabinet door.Inside the locker was a small moisture-proof cabinet with a small sailboat padlock.Lin Hanlong took out a bunch of keys from his belt, picked one out and opened the lock—the humidity here in Lingao is very high in summer, and moisture-proof work is essential——he took out his treasure from inside: a cowhide belt with tools, Hanging on it are a bunch of tools and measuring tools brought from the original time and space: a Fluke multimeter with complete functions; a strong flashlight, the original lithium battery is no longer usable, I wonder if Zhong Lishi can make one substitute?He took out a calculator from the computer bag he carried with him. It was a TI graphing calculator that he bought at a huge price before crossing, and it was powerful.He inserted these things into the corresponding positions on his belt.Finally, he stuffed the entire computer bag into the moisture-proof cabinet and locked the cabinet door.

"Boss Lin! These are today's data." One of the teenagers in overalls saw him coming out, and hurriedly handed over a big thick notebook.These two teenagers are students, and according to the school system, they have to spare some time every week to participate in labor in various factories.

Lin Hanlong took it and took a rough look: "Go, let's check the stove."

The furnace is a newly repaired annealing furnace for optical workpieces.A boxy black box sealed with refractory bricks.There is a door on the upper side that can be pulled open, and then the workpiece can be pulled out along the slide rail.The lower part is a stove, and a gas bag outside the workshop is connected in, and there are adjustable fire doors and tuyeres.There are several simple pointer instruments on the top of the annealing furnace, without even a glass cover, and the scale plate under the pointer is hand-painted.

Whenever glass is manufactured, the process of glass annealing is generally involved.Lin Hanlong sometimes wonders why the protagonist who burns glass is never injured by glass shards when he reads the novel?As a general rule: rapidly cooled cast glass products are subject to high mechanical stresses inside.Thicker glass blanks are in danger of bursting as soon as they are processed.Therefore, there must be an annealing kiln in the glass factory to anneal the finished glass: reheat the blank to a temperature close to melting, and then let it cool slowly.As for what temperature is suitable and what is the cooling speed, this is the specific process of the glass factory.When Xiao Bailang started the glass factory, although he built an annealing kiln and retrieved a manual from the Great Library, the production conditions in this time and space are different from those in the old time and space, so they cannot be used in full.The specific temperature and time are accumulated bit by bit by the veterans and workers of the glass factory.

Now Lin Hanlong and his subordinates have to go through groping to correctly grasp the temperature control data of optical glass products.The teenagers from the two schools are human flesh temperature control devices, and they try to keep the temperature in the furnace on the predetermined descending curve as much as possible.

As soon as I got close to the annealing furnace, I felt hot.Lin Hanlong has gotten used to it. Although the ventilation in the workshop is not bad, the outside temperature is [-] degrees now.There is no other better way to cool down than to engage in mechanical forced ventilation.

Lin Hanlong handed over the notebook that recorded the data to his apprentice: "Junjie, take a look at this data."

The apprentice looked at the data and charts carefully, and then raised his head: "Master, I think the data this time is very good." The two teenagers next to him were obviously relieved.

Lin Hanlong clicked a few numbers. "What do you think of these data?"

The apprentice thought for a while: "I exchanged the thermometer, but the reading is still low, which means the problem is with the furnace itself."

Lin Hanlong hummed, took out the multimeter, and connected a thermocouple probe.Then insert the probe into the measuring hole on the top of the furnace.He turned the monitor around to show his disciples.

"Both sides are the same."

Lin Hanlong nodded. "Then do it again during the next renovation."

He turned to the two teenagers on one side: "You can turn off the fire of the stove and let it cool down naturally. Tell your successor that the stove should not be turned on until it is at least [-] degrees."

Lin Hanlong then walked to a spherical grinder.Since he made the first manual grinder, the machinery factory has made four new special grinders.The one in front of me is the latest one, with roughly the same structure. The biggest change is that the power has been changed to a drive shaft + belt. At the same time, a large number of metal parts have been used instead of durable wooden parts. In addition, there are many more devices for adjusting various parameters. .Right now, the grinding machine has been dismantled into eight pieces, and all internal organs have been pulled out and placed on the floor.Lin Hanlong squatted down and stared at a bevel gear the size of a watermelon, several teeth on which had been broken.

"Junjie, go to the office of the Ministry of Science and Technology and call Chief Sun Li, and tell him that I invite him to come over."

The new equipment broke down less than a week after it was put into use. Yesterday, Lin Hanlong dismantled the grinder himself to check whether it could be solved on the spot, but found that he couldn't solve the problem.

The apprentice agreed and went out.Lin Hanlong stood up and walked towards the other corner of the workshop.

A thin middle-aged man rushed forward to meet him, nodding and bowing. "Master! Ah, chief, hello chief." The native middle-aged worker who had become a monk on the way would have jumped up and followed Lin Hanlong as soon as he entered the workshop.After being reprimanded many times by Lin Hanlong, he was finally able to stick to his post.He pointed out several large glass bottles to Lin Hanlong like presenting treasures.

"Look, chief, the stone powder has been crushed according to your order, and they have been sieved separately."

Lin Hanlong glanced at the machine behind the middle-aged man, "How is the ball mill?"

"Okay, very good."

Lin Hanlong reached out and picked up the work notebook hanging next to the machine:

"Is there any looseness? Is the vibration normal?" Originally, the operator should write the work record of the machine, but the workers who are still in the literacy class can't fill it out.The students from the national school can still help out when they come, but Lin Hanlong has already assigned them jobs, so he simply fills them out by himself.

It took Lin Hanlong almost an hour after he got to work to fill in the records, inquire about the equipment, and check the inventory and products.

When Lin Hanlong was about to finish filling in the records, he heard someone calling him, and when he looked back, Zhan Wuya, Sun Li and others were walking towards him.He brushed a few strokes to fill in the record, signed it, and put the notebook back.

Veteran technicians of the machinery factory gathered around the broken spherical grinder.

"It's obviously a casting problem. Look at this, isn't it a typical backlash?" Lin Hanlong pointed to the section of the part.Everyone nodded, but no one spoke.

The bevel gear was cast, but apparently something went wrong during casting.

"Hey, it's inevitable." Zhan Wuya came out to smooth things over, "The parts that need to be returned to the scrap warehouse are piled up, and the people in the reliability office can't even do failure analysis."

"It doesn't matter if it's broken, just don't break my glass." Lin Hanlong didn't intend to go into it. This kind of thing happens every day in Quanlingao. Even the cannons used on warships have broken gears and other accidents. , let alone here, "Can it be repaired?"

Sun Li, who had been looking closely at the section, shook his head: "I'm afraid it won't work. The cracks are visible to the naked eye, and you don't know how deep they are without flaw detection." He gestured, "If there are no cracks, it can be done by cold welding."

Zhan Wuya patted Lin Hanlong on the shoulder. "I'll make you a better one." After the war, the production of munitions slowed down, and there were still some materials that had been prepared, so Zhan Wuya spoke with confidence.

"Make it a new week and you'll get it to the one on the surface grinder first."

Lin Hanlong shook his head. "The flat grinder can't move, the binoculars are in a hurry."

Zhan Wuya snorted.The first batch of products of the Optical Factory included the 8x monocular binoculars used by the three-year army (trial), which is actually the simplest refracting binoculars with a bamboo tube for protection and carrying.The navy is dismissive of such crude things, they require good vision, high light transmittance, easy to hold, good sealing, corrosion resistance and so on.They asked for binoculars, so that they could compare with the army's equipment at once.A large number of binoculars require a surface grinder to make right-angle prisms, which involves additional investment and expansion of the optical factory.Fortunately, Wang Luobin, who is far away in Sanya, also supports the construction of binoculars-he can make them fixed and place them on various watchtowers.As a major in optics, Wang Luobin also emotionally supports the expansion of the optical industry.

"If you grind it flat, you can get everything together in at most three to five days." Zhan Wuya paused. "Army, soil, navy, ocean, you're right. I don't know what the navy wants?"

Everyone chatted for a while, and gradually dispersed.For others, it's close to dinner time. After eating and doing something, they can start the night's rest and entertainment. If they have energy, they can hug the maid to roll the sheets.But Lin Hanlong's day had only just begun.The temperature is relatively stable at night, which is conducive to the processing of optical parts.More importantly, he can monopolize the power output and network of the Ministry of Science and Technology.

At five o'clock, "light music" blared from the loudspeakers all over Lingao.People who work everywhere know that this is the call for the night shift workers.When the music is played again, the night shift supervisors of each workshop will roll roll at the door of the workshop, and then hand over shifts with the workers of the day shift.Workers from the optics workshop came one after another, belching and shaving their teeth, and joking with each other.All the small restaurants on the street will serve dinner in advance before the night shift workers go to work, so that they can go to work full of food.

Before the second music sounded, everyone was already there.Lin Hanlong stood aside with his hands behind his back, watching his workshop supervisor assemble the workers and line them up, and roll their names according to the roster.Lin Hanlong thought to himself that these people could be lined up neatly like an army, and the working class really has a natural organizational discipline.It's a pity that although most of these people are young, except for a few strong ones, most of them are thin due to long-term malnutrition, and they may not be of much use if they are really dragged into the battlefield.Thinking of this, he couldn't help shaking his head.

"Boss Lin! All the night shift workers in the optics workshop should have 37 people, but there are actually 37 people. Please give instructions!"

Lin Hanlong coughed and walked up. "Comrades! I will talk about one thing today. Everyone knows that there was something wrong with the No. [-] grinder yesterday, and some debris flew out. I want to emphasize that first, our mechanical safety measures are very good. The debris was The safety net blocked it, and no one was hurt. Second, our safety awareness is still insufficient, and we don’t have a good grasp of safety regulations. After the grinder broke down, there were people watching, but no one pulled the emergency stop lever. This is not acceptable! It’s getting heavier. Say, this is courting death!"

Seeing that the people below still didn't respond, Lin Hanlong sighed in his heart, and his tone became severe.

"In the future, if this kind of thing happens again, if you don't follow the safety regulations, you will be deducted money! The team leaders should pay special attention, you are directly responsible. In addition, we will conduct safety drills from time to time, starting tonight." The eyes of the workers changed. serious.Withholding money is a serious matter.Safety drills take up rest time, so it is also a serious matter.

Lin Hanlong was very satisfied to see the workers watching him attentively. "That's it. Let's get to work."

The safety officer in the workshop checked the power transmission system of each piece of equipment, and then checked the gas valves. Finally, he lit the gas lamp in the workshop, and the dimly lit workshop suddenly became bright.It was thanks to gas lamps that industrial large-scale night shift production in Lingao became possible.Every time Lin Hanlong saw this scene, he felt that the person who invented the gas lamp had made at least as much contribution as Edison in this time and space.

The glass workpieces to be processed have been “plated”—meaning that they are firmly stuck in a conical shallow metal tray with a glue made of pitch and beeswax, and then the tray is fixed on a spherical bracket with screws. Finally the whole bracket is installed on the rotating shaft of the grinding machine.Workers in the grinding machine class work in pairs to confirm that the parts on the plate are consistent with the settings on the grinding machine according to the work order.

The two people from the abrasive group of the general affairs class also sent the adjusted abrasive paste to each grinding machine according to the work order, and then started to adjust a new batch.Workers on shifts are also busy mechanically pressing a new batch of workpieces into metal pallets.This is a very demanding job. The action of pressing into the workpiece must be fast while the glue is still hot, and it must be absolutely guaranteed not to be crooked.A team of two in the mechanical class is busy starting a grinder that has been prepared.The machine has been tested manually and there is no problem, it has been lubricated, and the grinding machine team has also confirmed that everything is normal.

According to the work order, this grinder will be used for rough grinding tonight, and the selected speed is faster, so the belt needs to be moved to a transmission wheel with a smaller diameter.After moving, re-tension the belt, and then move the clutch lever, so that the fixed transmission wheel on the top of the head is combined with the main power transmission shaft.There was a creaking sound from all over the machine, and then the grinder turned, and the noise slowly died away.The mechanic glanced at the tachometer, signaled to the grinder that everything was fine, and stepped back to start filling out the job log.Grinder workers pick up a small brush and dip it in abrasives, carefully place it on the rotating workpiece.After a while, all the workpieces were covered with abrasives, so the grinding disc was put down and let it swing back and forth.This grinder enters normal working state at this point,
Not long after, other equipment in the entire workshop also roared one after another, and the night shift production of the optical car officially started.

Lin Hanlong walked around the workshop again, paying attention to any abnormal conditions and noises. Then he returned to the door of the office and saw Wu Nanhai sitting on the long wooden stool in the rest area of ​​the workshop.

"Huh? Old Wu, why are you just sitting here without saying a word?" Lin Hanlong was a little surprised,

Wu Nanhai, who had witnessed everything, let out a sigh of relief: "Old Lin, you are really meticulous here, hahaha.

Lin Hanlong motioned for him to come to the office to speak.Several naturalized staff members, as well as Chu Qing, were already waiting at the door of the office.He glanced at Chuqing, and remembered the limited-edition cigars that had been forwarded to him——Wu Nanhai asked him to try out a batch of magnifying glasses, so he specially sent him a few packets.

"Rare customers, rare customers." Lin Hanlong called his apprentice to serve Wu Nanhai tea and water: "I don't have anything here, and the hospitality is not good enough."

"It's okay, it's okay, we are also here for work!" Wu Nanhai laughed, "Last time I said I needed 50 magnifying glasses, and you finished it in a month, which is amazing."

"If it takes a year to do it well, we don't need to do any industrialization." Lin Hanlong said, while taking the towel wrung for him by his apprentice, he wiped his face.

"By the way, I heard that Ming's Nanjing can make aging glasses and so on, using crystal chips to grind them. Would you like to make a report and get some indigenous glasses workers to help?"

"Of course it's good to have it, but I don't think it's very meaningful. How many pieces can this kind of manual craftsman make in a day? It's nothing more than a luxury that only high-ranking officials can enjoy. I'm machine grinding now, even if the quality is not as good as them for the time being, at least the cost It can’t be compared with the output.” He paused, “I am very interested in crystals. I heard that there is a large crystal mine in the East China Sea of ​​Lianyungang…”

"Hehe, the people from the long-distance exploration team said last time: Hainan has a good crystal mine."

While the two were talking, someone outside pushed a flatbed cart over.Lin Hanlong motioned for someone to take a flat wooden box from the car and put it on the ground beside the two of them.Open the box, inside is a layer of grass mat.Remove the straw mats to reveal five small boxes, which are also separated by straw mats.Lin Hanlong reached out to pick up a small box and opened it.Inside is a magnifying glass embedded in the fleece at the bottom of the box.
