Big Country Intelligent Manufacturing

Not long after, Xu Zhenming and others came to the riveting workshop.

In the workshop, two scrapped auxiliary platform workpieces have been stacked.The third workpiece is half welded, and the amount of deformation is very large, and it is considered scrapped and can no longer be used as a qualified accessory.

The material designed by Xu Zhenming for this auxiliary platform is welded with 2 mm thick Q235 galvanized steel plates.Such welded parts are indeed more difficult to manufacture and process.Because the steel plate is relatively thin and requires "full welding", the deformation is very large.General electric welders are not allowed to work, and will burn the steel plate through.

Full welding is one of the welding technical terms, which means that when the workpiece is welded, the entire working surface must be welded to form a closed surface.The opposite is "segment welding".

Segment welding refers to the welding of the welding surface in sections, and a section of the weld is welded at a certain distance.This welding process is generally used on thin-skinned workpieces.

The auxiliary platform of this machining center must be filled with cutting fluid and must be fully welded without water leakage.Moreover, this workpiece is made of galvanized sheet.You must be careful when welding galvanized sheets. The gas generated during electric welding is toxic and will damage the health of electric welders!

However, this kind of workpiece cannot be welded.Xu Zhenming's original staff had several welder technicians, and they were able to weld steel plates of about 1 mm, and they were fully welded.

At this time, the two riveters and one electric welder who were responsible for making the auxiliary platform stood there sadly and sulking.

"This drawing must be changed! How can a 2mm steel plate be fully welded!"

"Yes! Isn't this tossing people!"

"Both of you keep your voice down! I heard that the drawing of this work piece was designed by Mr. Xu himself!"

The three workers looked at the workpiece sadly while talking in a low voice.They are helpless unless they change the original design drawings.

Seeing the expressions of the three workers, Xu Zhenming could also guess that they were full of complaints at this time.While walking, he observed the welding tooling of the auxiliary platform.

Tooling is a relatively high-tech process in the production of welded parts. It is generally made by experienced riveters to assist in the assembly and welding of welded parts.

Ingenious tooling can improve the speed and accuracy of welding parts.Therefore, the veteran riveting master is very popular, and a group of electric welders are walking around him.Later, the small boss engaged in steel construction contracting was generally an experienced riveter.

At a glance, Xu Zhenming could see that the auxiliary tooling of the auxiliary platform had a problem and could not effectively grasp the welding parts in the tooling.In addition, the process of welding the workpiece is also problematic. The continuous electric welding on one side will concentrate the internal stress of the workpiece on the other side.

After seeing this, he called Sun Ziliang, the riveting team and others to his side, pointed to the workpiece on the welding platform and said:

"First, there is a problem with this tooling. The thin steel plate that cannot effectively resist the workpiece is a strange thing if the workpiece does not deform during welding! Second, the welding of such thin plate workpieces is generally done by segment welding. It is produced by symmetrical welding, and electric welding must not be continuous, but the welds must be welded in batches..."

Although Xu Zhenming is not a welding engineer, he has rich experience in welding.He talked about the experience of welding thin-skin workpieces in a gentle tone, which opened the eyes of the workers present.

Welding is also a profession, and a dedicated engineer is responsible for theoretical guidance and formulating welding procedures.Yiming is in the initial stage, and there is a shortage of talents in this area.

Therefore, Xu Zhenming temporarily acted as a welding engineer, instructing several workers on site to re-make tooling, re-assemble the workpiece, and re-weld.This time, two electricians are working at the same time, symmetrically welding the workpieces on the inner and outer sides of the auxiliary platform according to the drawn lines.

After the first batch of segment welds are welded, the workpiece is clamped by the tooling, and the amount of deformation is small!

After the workpiece has cooled down, the situation remains the same after the second batch of welding.

The third batch... until the workpiece is welded, the deformation of the auxiliary platform is not very large!

At this time, the squad leader of the riveting group was convinced and raised his thumb.

Everyone is happier. Through the welding of this auxiliary platform, they have all learned a thin-skinned workpiece welding technology, which will benefit for life.

"Because this workpiece is a hot-dip galvanized part, it is inconvenient to send it to the heating furnace for normalizing treatment. You must use the vibration method to eliminate the internal stress of the workpiece after welding!"

Seeing everyone's excitement, Xu Zhenming urged the grandson beside him.

All welded parts have internal stress.If the internal stress is not released, it will affect the accuracy and service life of the product!

Some workpieces are heated by entering the heating furnace and then cooled to release the internal stress in the workpiece, which is called normalizing.Some workpieces are too large, and the internal stress can only be eliminated by hitting the weld seam of the workpiece. This is called the vibration method to remove internal stress.Shipbuilding adopts this process to eliminate internal stress!

"Okay, boss Xiao Xu! Just do as you say!"

After hearing the words, Sun Ziliang nodded with a smile.At the same time, he also recorded all the scenes he saw today and prepared to compile a booklet on welding technology to train all riveting welders.

Busy, it's time for dinner again.Workers on day shifts have to explain their work to the workers who come to take over before leaving get off work.

The riveting workshop has started four shifts and three operations, divided into three shifts: day shift, small night shift and large night shift.Therefore, they all attach great importance to handover.

Yiming adopts a working-hour piece-rate system, and everyone's income is related to their own output.

Under this system, no statistician is needed in the workshop to figure out the output of each team.The employees do not want to suffer, and will report their workload truthfully.Once the report is over, the workers on the next shift will not be willing.

This is the beauty of institutionalized management!

After taking a look at the employees who were earnestly handing over their shifts, Xu Zhenming went to the heavy-duty factory to inspect.

In the heavy-duty factory, workers who are about to leave are also busy handing over shifts.They have to install all the machine tools in place according to the technical requirements. The workload is relatively large, and it cannot be completed quickly in a short time.

"Naruko! When is the estimated time for the heavy machine tools you mentioned to be in place?" Seeing Xu Zhenming coming, Ma Jimin asked Xu Zhenming with a smile.

In the heavy-duty workshop, Xu Zhenming reserved the foundation for two heavy-duty sleeping cars, a heavy-duty grinder, a planer, and a heavy-duty boring machine.The equipment has been entrusted to Suning General Machine Tool Company to find the seller, and the machine tool installation foundation is also designed according to the machine tool to be sent.

Once these machine tools are in place, Yiming's heavy-duty machine tools are fully equipped.

According to Xu Zhenming's equipment theory, these heavy machine tools are "battleships" in machine tool equipment.Once the battleship is configured and equipped with some small and medium-sized machine tools, Yiming's "manufacturing equipment fleet" can set sail!

Thinking of this, Xu Zhenming said to Ma Jimin with a smile: "Director Ma, those heavy machine tools will be delivered to the company soon! According to the old rules, you will arrange manual maintenance for the machine tools as soon as they arrive, and install them after a thorough inspection! "

Hearing this, Ma Jimin smiled and nodded.

He was born as an old machining worker, and the most happy thing is that he has more and more machine tools.He was born as a soldier and likes the theory of "manufacturing equipment fleet" summarized by Xu Zhenming the most.I love the machinery manufacturing industry from the bottom of my heart, it doesn't matter if it gets dirty and tired!

Therefore, Ma Jimin, an old man who was going to wash his hands after get off work, had to accompany Xu Zhenming to inspect the machine tools installed in the heavy-duty workshop.

These machine tools are replaced with damaged parts, refilled with putty, and repainted. The oily areas are wiped shiny, just like brand new machine tools.

The old man really likes machine tools!Every time he passed a machine tool, he would stop and touch this, look at it, check it, and treat the machine like a pet.

Seeing his focused expression, Xu Zhenming couldn't help but his eyes moistened.

"Master! You should go back to rest after get off work! Don't work too hard, my factory still depends on you to fight the world!"

After a round of inspection, Xu Zhenming sent Ma Jimin away with a smile.Then, he was ready to go to dinner.

Back in the staff canteen, all the staff on the night shift had finished their dinner, and left in twos and threes.Li Quan's family and Xu Zhenming's family are sitting together for dinner.

Li Quan is on the night shift today. After dinner, he is going to be on duty in the machine repair shop.

Therefore, he did not drink and was chatting with Xu Youkui."Naruko! How is the progress of the machine tool installation? When will Yiming Company resume production?" He asked with concern when Xu Zhenming came with a smile on his face.

"It's the end of the month! It seems that at the end of the month, you can put Suning's order business into Yiming Company for production! Move in early and feel at ease!"

Xu Zhenming picked up his job and told Li Quan the latest situation.

In the machine repair shop, he always feels unreliable when he is doing the business of the shaver, and he has an inexplicable sense of urgency in his heart.

After hearing about this plan, Xu Youkui felt very urgent.He was helping his brother-in-law Li Daoben's construction team to clean the office building, so that the office building was handed over to Yiming Company as soon as possible.

Li Xianghe is also very busy at night. He wants to help Xu Zhenming clean the office and bedroom on the third floor so that his eldest son can move to Yiming's company as soon as possible.

The family was very busy, and Xu Zhenlian came to Honghe Township with no one to take care of.Fortunately, she is a sensible little Nizi, and she doesn't feel alone.

"Lianzi! You can live in our house tonight! We can be a company and take care of each other while studying!"

At this time, Li Xiaoya invited Xu Zhenlian very sensibly.Her cheeks were slightly flushed, and she was as smart as Xu Zhenming remembered.

Hearing these words, Xu Zhenlian turned her head and looked at Xu Youkui and Li Xianghe with longing eyes.

Xu Youkui and his wife did not want to trouble Meng Ping, their eyes became a little stern, and signaled their daughter not to go to Li's family to trouble others.

Xu Zhenming was very happy to see that the younger sister liked to associate with Li Xiaoya.He smiled and persuaded his parents: "Father, Mom! The whole company building is undergoing renovations, and the noise is too loud. The little girl is not at ease studying here, so let her live with Xiaoya for a few days! My master is also My godfather, I am not an outsider!"

"That's the reason!"

Both Li Quan and his wife nodded with smiles.

Therefore, Xu Youkui and his wife also accepted Li Xiaoya's kindness.

Send the little girl to Master Li's family, and Xu Zhenming sat on the bag rack of Master Li Quan's bicycle and came to the machine repair shop.He does not have a driver's license, and he is generally unwilling to touch the steering wheel for fear of unnecessary tingling.

As usual, Xu Zhenming and his master Li Quan started to make a round of inspections in the machine repair shop to keep abreast of the status of the haircutting knife business.

Fortunately, the situation was relatively normal, so he left with peace of mind.Having just returned to their temporary office, Daxia Yang and Li Dayan knocked on the door grinningly.
