Return to the exciting era of 1999

Chapter 210
The web is still formed by stamping, and the 45th iron block corresponding to the weight is burning red and white in the furnace, and the large pliers are directly pulled out and thrown into the mold.

"Empty!"

The metal block gradually turned into a discus, and then the discus was clamped, and the bottom was dropped into the punching mold, and the huge hole in the middle was dug out in two or three strokes.

The next step is simple modeling, and so on, the whole process fully demonstrates the violent aesthetics of machinery, and the blood of a group of students who are new to casting is excited.

More than a dozen cylinders have been cast, and the first cylinder has been completely cooled, and the crane lifts the cylinder into the lathe for roughing.

The entire internal cavity is cleaned with a long-arm cutter, and the dimensions of the turning tools on both sides are positioned.The surface of the outer pulley requires little turning and is simply aligned.

The next step is that the shaft head enters the lathe to be processed to the size of the semi-finished product, and the shape of the web is finished, and the two are combined with the direct spot welding and the refined cylinder.

"Zizzizi..."

The web, shaft head, and cylinder are completely combined, and with the sparks of oxygen welding, the entire workpiece slowly becomes one.Wait until the workpiece is completely cooled, and the welded parts are processed on the machined surface for the second time to ensure the concentricity of the shaft heads on both sides.

"Master Qi, in the last step, just use a planer to plan the grooves on the surface, and then wait for me to hang the glue."

Watching the workers strictly follow their own crafting route, Ji Donglai nodded, and Da Qizi heaved a sigh of relief. As a skilled worker, the most worrying thing is to follow a leader who doesn't know anything and give directions blindly.

No matter in state-owned factories or private enterprises, there are those two pens buzzing in the ears of skilled workers.Say you are wrong about this and that is wrong, and give you random instructions.

If you don’t follow his requirements, it means that you don’t respect the opinions of the organization. After listening to their opinions, you process waste products and say that your level is not up to standard.

Ji Donglai just watched the entire drum processing process, without saying a word of nonsense, no matter whether the other party understands it or not, the respect for the workers is admirable.

"Okay, boss, you don't have to follow, we will tell you when we finish all the processing, it will take three days to finish all the processing!"

It was completely dark, Da Qizi wiped the sweat from his forehead, Ji Donglai nodded.

The rubber material at the rubber manufacturer was also working overtime for processing. Ji Donglai greeted Ding Aixing, and whispered a few words in the other's ear, and the other party hurried to SJZ.

At noon the next day, Ding Aixing and the vehicle transporting the rubber arrived almost simultaneously.

"Brother Donglai, is it this? This thing is not easy to buy!"

As Ding Aixing said, he took the release film off the car, Ji Donglai briefly looked at it and nodded, and asked the workers to poke the entire rubber on the car into the workshop.

"Fortunately, the rubber is thick enough! The shaft head is connected to the reducer, you guys followed me and stretched it..."

Stretching out his hand to pinch the rubber material, Ji Donglai still very carefully asked his subordinates to take out a piece to make a test piece, and he led all his subordinates to start winding the whole roll of rubber on the processed metal roller.

Bearings are installed on both sides of the surface of the roller with planed lines. The adhesive sprayed on the surface has completely dried up. The reducer above the roller drives the roller to slowly start rolling the rubber sheet on the surface of the roller to ensure the sealing of the film and the roller.

According to the drawings, the surface of the steel rod needs to be wrapped with [-] thicknesses of rubber. Ji Donglai pressed the head of the rubber sheet into the pitted surface of the steel rod, and then started the reducer connected to the rubber roller.

With the slow start of the reducer, the film between the driving wheel and the driven wheel is gradually straightened, and gradually the rubber film becomes tighter and thicker. On the No.15th floor, Ji Donglai nodded, and the reducer stopped.

Ji Donglai directly smashed the rubber sheets together, and then covered the entire surface with a release film, while winding it, and driving the air with a metal rod towards one side.

"On the mold, pay attention to the torque of the clamping bolts, it should be over 25 Nm!"

After the rubber on the entire surface of the metal rod was wrapped, Ji Donglai gave an order, and the cylinder mold was snapped together.The bolts are locked, and the workers send the whole hanging rubber roller into the furnace.

Repeatedly, all fifteen rubber-covered rollers finally entered the furnace. With the workers sealing the furnace surface, Ji Donglai set the temperature of the furnace at [-] degrees and turned on the power.

"Waiting for three hours to eat roast duck, just look at it occasionally, as long as the temperature doesn't drop by accident!"

The process of hanging rubber rollers is not difficult, but the whole process is very slow, time-consuming and labor-intensive, and the practice of large factories is the same without exception. Ji Donglai washed his hands and asked the workers to solidify various processes.

Ji Donglai still does not plan to use the machining center for the next crafting process, because he drove away Livit, and Ji Donglai assigned almost all of Swell's molds to himself, and occasionally handed over some that he didn't like to process to Zhang Yu.

Now there is a golden rooster that lays its own eggs, and there must be no time to be idle. In addition, workpieces are constantly being delivered from the elevator factory, so it is necessary to ensure that the high-quality steel of the machine tool is used for the blade.

"Give this drawing to Master Qi, find the bevel gear in the waste we received, and then design a knife rod telescopic mechanism with two chains. My design is like this. Let them look at the specifics. That's right!"

Ji Donglai used UG to simulate a machine tool processing, which is similar to a car differential. On the surface, Ji Donglai added a chain-driven cam to drive the turning tool bar to ensure that the turning tool bar can expand and contract on the outer surface of the roller as required.

The surface fixing of the main tool holder was all designed by a few old technicians on site, and Ji Donglai was too lazy to do the rest. After all, now that there are engineers, Ding Aixing promised to find some old masters, and they immediately erected the drawings after they got the drawings. thumbs up.

"This little boss is not easy to fool, a [-] bed can give you a three-axis research, this alone can make our group admire, you do it!"

Da Qizi and the old turner took a look at the drawings, and finally handed them over to the old mechanic. The other took a sip of water from the big tea mug, lit a cigarette, and led the young apprentice into the scrap iron workshop.

Invite everyone to start looking for waste gears and shafts according to the reduction ratio.

It is not far from Tianjin Port. Most of the scrap iron comes from scrap ships in Tianjin Port. The quality of the metal is not bad. Similar parts were found soon, and there is no problem for the old technicians to process and transform.

Ji Donglai hardly participated in it. When the rubber roller came out of the oven, Ji Donglai came to the scene to have a look.

"Hey, I'll go, it's like a leaked egg, it's runny!"

Rubber flowed out from the side of almost every rubber roller. As the car pushed out of the furnace, Ji Donglai carefully inspected each rubber roller.
