Rebirth 2008: I Can Make Money Reading

Chapter 44 Start processing and assembling (recommendation ticket requested)

Mu Yang has thought about it, he can currently earn 20,000 yuan a day as a reward for swiping money, if he spends more money and hires more people to do things, it is indeed a good deal.

But he is doing business, and he is also training himself. If the workload is not heavy, he can do it by himself and experience it for himself.

In case the reading system no longer rewards money one day, and his ability has not improved, what will he use to make money.

An hour later, Mu Yang took some parts drawings to the workshop and called all the workers in the workshop to gather and arrange work.

There are few people, and there is no need to hold meetings. It is too time-consuming.

Distributed the drawings to the workers, and ordered: "The personnel are not yet in place, you cut the materials according to the requirements of the drawings, and process the parts, the quantity is marked on the drawings.

We don’t have a quality inspector for the time being, but I request that the workpieces processed by you must meet the requirements of the drawings and be inspected by yourself. If the unqualified products are allowed to flow to the next process, there will be fewer quality scores at that time, which is related to you Quality pay, don't blame the auditors.

It’s okay to make a wrong processing, just scrap it, but I request that the processing be done after reading the drawing requirements clearly. If I really don’t understand, ask a colleague or call me.

It must be done strictly according to the drawings, don't feel that it doesn't matter, it must meet the tolerance requirements of the drawings.

Some raw materials have not arrived yet, and they may arrive in the next day or two. The quantity is not large, and they will be mailed directly to the guard. Master Chen, you are responsible for registering, receiving them, and then putting them in the raw material area. "

Mu Yang told a welder named Chen, who was the oldest.

Some parts have been processed since the recruitment of workers, and in two or three days, small parts can be assembled.

"Okay, boss." Master Chen took the blueprint.

"Well, I have listed a production plan schedule with production time nodes marked on it. I will post it on the big display board in the welding area later. You can pay attention to it when you have time, and tick it off when you are done."

Mu Yang explained the matter, and reminded before leaving, "By the way, these drawings are confidential and cannot be passed on. After everyone finishes processing, they must recycle the drawings.

If you can complete the task on time and according to the standard, I will give you another reward, and I hope you will take it seriously. "

After Mu Yang left, the workers also talked about Mu Yang in private. After all, he was too young, and at first they thought he was a rich second generation.

In the next few days, as the workers processed the parts, Mu Yang began to assemble the equipment.

Mu Yang wants to build more than five plasma spray welding equipment, and the cost of mass-manufacturing the welding turntable by himself is much lower. His requirements are higher, and the manufacturing cost of each positioner is estimated to be about 3,000 yuan.

Plasma spray welding equipment itself is mainly composed of rectifier power supply, control cabinet, powder feeder, spray gun and so on.

The complete machine for overlaying cobalt-based alloys is not sold, but these spare parts are still sold in the market.

The spray guns sold in the market can't meet Mu Yang's requirements, so they need to make their own.

For Mu Yang, the most important thing is the craftsmanship. Even if the equipment is given and the key techniques are not understood, the processed products still cannot meet the requirements.

Then, what exactly is the product that Muyang wants to surfacing?

This is the overlay welding of two layers of cobalt-based alloy STL6 on the sealing surface of the gate.

Why two layers of surfacing welding?

Wouldn't it be faster to directly surfacing one layer?

One layer of surfacing welding can also meet the thickness requirements, but the alloy composition cannot meet the requirements.

The main chemical composition of STL6 is about 29% Cr chromium, 4.5% W tungsten, 3% Ni nickel, 1.5% Mo molybdenum, no more than 5% Fe iron, and the rest is a large amount of Co cobalt and other elements.

The chemical composition has a qualified range, and the most difficult to control is Fe iron.

If the iron element exceeds the standard, the corrosion resistance of the surfacing layer will decrease, and the medium (liquid or gas) in the channel of the valve body will be corrosive. The gate will be in contact with the valve body for a long time. If it is rusted and stuck together, it will not be able to open Valve, this is not allowed.

Therefore, the iron element of the first layer of surfacing layer is not up to the standard, and it is difficult to control the iron element, so try to weld it as thin as possible and use it as a transition layer.

The iron element and other alloy elements of the second layer of surfacing layer can meet the requirements and meet the requirements of use, which is also the actual use layer.

For the argon arc welding of the traditional method of surfacing welding STL6, it is easy to weld a layer of weld seam at one time, but it is the most difficult to weld thin.

Moreover, it is even more difficult to control the composition of alloying elements in the surfacing layer.

The specific process is relatively complicated. Even a skilled welder will find it difficult to understand the meaning without guidance.

Mu Yang wants to make automation equipment, he will adjust the process well, as long as the workpiece is placed, one-button start can start welding, and the welder does not need to understand the specific process.

It can control the thickness very well. The thickness of the first layer is controlled at 1.5 mm, and the thickness of the second layer is controlled at 2 mm. The error will not be about 0.1 mm. Because the surface is uniform, it is enough to leave a machining allowance of about 0.5 mm.

Compared with traditional crafts, the advantages are very different.

two days later,

Mu Yang assembled the most critical equipment, and asked workers to assemble other unimportant equipment.

After installation, if the debugging is qualified, he has to weld the spray gun to death. If he wants to disassemble it, he can only do destructive wire cutting, which is not so easy to get out.

two days later,

The first plasma spray welding equipment of Xinghai Machinery Company was finally assembled.

Sorry, the writing is too professional, burning brain cells.
