Three days have passed, and the parts designed by Li Zhao have all been processed yesterday, and it took a total of ten days before and after, which is still not a very complicated piece of equipment, and it still took more than ten days to make all the parts in the case of surveying and mapping drawings in the early stage.

After signing in the morning, Li Zhao came to the fitter workshop, where the machine repair was already preparing tools. In fact, in a large factory like a rolling mill, it is very complicated to do things, just like now, you need to fill in a maintenance plan, and then send it for approval, and then you can repair it after approval. When repairing, it is necessary to open a power outage notice to the electrician, and the electrician needs to hang the maintenance card that prohibits closing after the power outage, and the maintenance needs to use the same electricity, and the electrician is also required to connect it before it can be used, and it is forbidden to pull the wire privately.

This is not over, the fire must be opened, the ascending permit must be obtained, the closed container must be entered, and the air of the closed container must be measured to meet the working conditions.

Since most of the internal parts need to be replaced, there are six people who come to repair today, don't think that there are fewer people, this is already a lot, usually two or three people cooperate with the maintenance, which is basically directly doubled, and no matter how many people there are, they can't stand. The workshop also arranged a person to cooperate, who was the operator of the machine, that is, the guardian sent by the workshop.

Today's maintenance is more complicated, the entire gearbox must be cleaned, and then the parts are added with new oil, the motor needs to be replaced with a shell, and the parts involving the feed all need to be dismantled and replaced, so this maintenance can be said to be basically disassembled into parts, and then reassembled. Fortunately, this machine is not complicated in general, so it is relatively quick to disassemble.

Li Zhao is busy dismantling the machine here, and some people are also busy, of course, it is not a good thing that they are busy. It's still the teahouse from last time, or the two people from last time, and the two are talking quietly again.

The person who only heard the stiff voice asked, "How is it, has the situation been clarified?" Who is better suited to start, and when can I schedule the action? ”

Another person said: "At present, Xu Damao is the most suitable person to start. We promised him that he could arrange a leadership position, but he wanted to steal something in the rolling mill, he wanted to be an official, but he didn't want to steal anything, and he actually promised that he would take care of our people after becoming a leader. ”

The man glanced at the man who spoke a little stiffly, and then said: "If it weren't for the person who arranged it at that time and said that if he dared to poke the matter out, he would take revenge on him, I guess he would have stabbed the matter up by now." As for Yan Bugui, almost, our people also thought that they would give him money and let him steal something at school, he wanted to take the money, but he didn't want to steal anything, and after refusing, he wanted to take advantage of our people. ”

"And the few people Xu Damao often hooks up with, we have all investigated, they are all local acquaintances, and they are not suitable for acting with us. I'm going to send someone to create a chance encounter on the weekend, so that he can knock people down, and with his characteristic of not being able to walk when he sees a beautiful woman, he will definitely take the bait. Then it was to catch the traitor, take his handle, and send him to the police station as a threat, let him sign a huge amount of compensation, and then force him to comply, and finally promise heavy profits, not afraid that he will not take the bait. As long as he gets what we want, it doesn't matter if he is dead or alive. ”

The man who spoke a little stiffly nodded and said, "Okay~, good~!" Mr. Liu's plan is perfect, so follow this plan and try not to use our people in person. ”

"Don't worry, you will be able to do it properly, and it will never be traced back to us." After saying that, the two of them continued to be like ordinary old BJ people, and they both left after a while.

After two hours, Li Zhao and they have almost dismantled here, is cleaning the gearbox, Li Zhao asked all to clean up, in fact, there is a reason, many times the maintenance is more sloppy, the gear is worn during use, there will be a lot of iron filings, these iron filings will be deposited at the bottom of the gearbox in the static situation, if not cleaned, it is likely to be stuck into the gear with the flow of oil, resulting in accelerated gear wear.

This time, since they were all replaced with new gears, Li Zhao asked them to clean up and maintain the entire machine. After cleaning up, Li Zhao first measured each part against the drawings, because the accessories designed by Li Zhao were based on the drawings, and if there was a gap between the drawings and the real thing, the designed gears were likely to be in vain.

A circle of measurement, there are two places due to the use of a period of time, and there is new wear, Li Zhao first marked out, and then discuss with the maintenance workers here to deal with the method, if not, then the new gear will also appear unevenly stressed, which will cause the problem of increased vibration and accelerated wear of parts.

In fact, the method is also very simple, generally either add gaskets, or surfacing after repair, obviously surfacing welding is too time-consuming, first use the gasket pad to see the effect, if the assembly is done after the test machine has too much vibration, it will be removed and repaired, if it is normal, then look at the changes in the use process, in fact, this situation will not be a problem after adding the gasket. But after all, it is a transformation of machine tools, and it is better to be perfect or perfect.

Lunch is arranged for the canteen to be sent directly to the post, Li Zhao also followed the maintenance site to eat, to be honest, they are really hard-working, just wash their hands in the diesel fuel that cleans up the parts, and then flush it in the faucet, and start eating. After eating, a few people spread sacks beside them, and then lay down to rest for a while, and soon when the time came to work, they got up and continued to assemble.

At three o'clock in the afternoon, the assembly was completed, and Li Zhao also called the workers who came to test the machine. It should be noted that in the factory, no matter who repairs or who, has no right to use the workers' machines, just like this kind of test machine, it must be carried out by the workers, and the rest of the people are not allowed to operate any equipment and facilities of others at will.

There are many accidents caused by tampering with other people's equipment and facilities, and once, someone was repairing the fan on the top of the evaporative cooling, and just opened the cover and was ready to repair it. The buddy who repaired on the top also made a quick decision and jumped into the pool next to him. The water in the pool is cooling circulating water, but fortunately the temperature is only fifty or sixty degrees. If it weren't for the pool next to it, the consequences would have been either hit by a fan of more than ten kilowatts, or it would have fallen from more than ten meters in the air.

Therefore, the factory is generally not allowed to move the equipment that is not in charge of itself, and it is the same here, first of all, of course, the detection of the external aspects, what is the level of each direction, the degree of parallelism, etc., if these are not adjusted, then the machine tool is likely to appear tapered when processing, so the adjustment is very important.

Then the operator starts to clean up, which is mainly to prevent any debris from hitting people or equipment during start-up. Then there is the crank, after the overhaul, first take a plate to see if there is a problem with the assembly of this equipment, if there is a problem, then it is very likely that the disc will not move when the car is turned. The results of the rolling are smooth, and then move on to the next item. Then check whether the oil and gas and other parts are normal.

Jog the equipment, that is, close, and then quickly disconnect, so that you can test whether there is an electrical fault, if not, then the equipment can operate normally, when everything is fine, then close, let the equipment run for three to five minutes, to determine whether the equipment has other problems, of course, there is no problem here.

The equipment has been started, Li Zhao also began to test the equipment, first of all, vibration and noise, at this time, the most intuitive impression, next to the boot is the one who usually operates this machine, he has the most right to speak. The answer is yes, under the fastest speed of the spindle, the vibration and noise have been greatly reduced, the noise was at least 100 decibels before the transformation, and now it is about 80 levels, which may be lower, and it has been reduced a lot.

Then test the accuracy, stop the equipment, put a workpiece, and start processing according to the drawing, but the processing speed of this equipment is still not fast, after all, the performance of various accessories is limited here.

After waiting for a while, the operator completed the processing of the workpiece, the workpiece is very simple, it is a processed cylinder, with a diameter of 100 mm and a length of 300 mm, Li Zhao's requirements are also very simple, every 30 mm car a step, the diameter of the step is designed, and the master only needs to directly turn the car according to the requirements, so that you can see how far the machining accuracy in all directions can be reached.

The measurement is measured with a micrometer, mainly measuring the diameter, height, level, eccentricity, etc. of each step. Today's master who operates this equipment is a sixth-level worker, and the basic skills under his hands are quite solid, the equipment is also well adjusted, and the final accuracy test has also reached expectations.
