Chinese In fact, He Xiaojun knows that since there is such cutting equipment here, someone will definitely use this equipment. The reason why he, who has always been low-key, wants to go into battle in person is not that he wants to show off, but that he doesn't know what the skills of the people who will use this setup here are? If this material is not opened well, it will take a lot of work later, so he simply went into battle in person.

Following He Xiaojun to the arrival of the people, because they were laymen, they felt even more surprised, the iron was hard enough, how did it get into He Xiaojun's hands, it was like tofu, and he could cut it as he wanted?

In addition, from the same surprised expression of Technician Xu, everyone estimated that He Xiaojun's work at this time should not be easy, and it was a difficult job, so everyone felt even more mysterious and admired for this young man with endless skills.

It only took a few minutes, and after cutting the two outer crescent-shaped steel plates, He Xiaojun took the cut steel plates and put them on the hook again, and after confirming that there was no problem with the shape, he used these two steel plates as a benchmark to make the two curved materials inside and outside the hook.

After cutting the prepared steel plates into rectangles first, and then using the cut air gun to burn the two rectangular steel plates red and bend them into a crescent-shaped arc to match, the raw materials He Xiaojun needed had been processed.

In this link, the laymen who followed He Xiaojun were even more curious, how did the usually hard and abnormally hard steel plate get into He Xiaojun's hands, as soft as mud, and let him play with it?

If it weren't for the fear of disturbing He Xiaojun's work, someone like Miss Er who couldn't hide his words would have asked him questions a long time ago.

After handing over the cut and made materials to Technician Xu, and instructing him to polish the perimeter of the materials neatly, He Xiaojun walked towards the damaged hook.

At this time, the damaged hook had already been processed by Technician Xu according to He Xiaojun's instructions.

He Xiaojun asked Xu technician to process the damaged hook, that is, to process all the broken edges out of the groove, so as to increase the welding area and the depth of the welding to the workpiece, so as to strengthen the welding connection.

After touching the two parts of the hook with the groove together, He Xiaojun personally grabbed the knife and welded the broken hook.

Before welding, He Xiaojun warned the crowd who had been watching with him: The arc light produced by welding is thousands of times stronger than the sun's rays, and if these arcs are shot into the eyes, they will cry endlessly; If you are shot on the skin, it will peel, redden, and heat up as if you were exposed to the sun, so you should stay away so as not to be shot.

After the public dispersed, He Xiaojun first fixed the two parts of the broken workpiece with spot welding, confirmed that the two parts were anastomosed, and then carried out full welding.

At the time of full welding, in order to ensure the success rate of this process, He Xiaojun used all kinds of tricks that he had seen in books and practice in his previous life. For example, the opposite side is welded at intervals to ensure the balance of stress and reduce the deformation caused by the machining process; Another example is to use a cutting gas detector to heat while welding to eliminate the concentration of stress; After half an hour of welding, He Xiaojun finally reconnected the broken hook and restored it to its original shape.

Let Technician Xu's people move the hook to its original state to its working position, and after trying that it has no effect on its use after restoration, He Xiaojun asked people to move it back and make an outer surround for it.

Stick the steel plate that you have opened the material and polished by the technician to the hook, or use spot welding to fix the shape and position of the outer surrounding, and then let people test the hook with the outer surround again, does it have any impact on the performance?

After the result that the hook can be used normally, He Xiaojun carried out a comprehensive welding of the outer envelope, and he also carried out a comprehensive welding of the entire part of the outer envelope in contact with the hook.

This made the welding firm, and He Xiaojun opened grooves in all the places that needed to be welded to increase the area of welding.

For some parts that cannot be welded on both sides, He Xiaojun uses the technology of "single-sided welding and double-sided molding", and uses methods such as separation and beveling to process the parts that need to be welded on both sides and cannot be processed.

After spending an hour welding all the parts that needed to be welded, and the auxiliary work that needed to be done was done, He Xiaojun checked the welded workpiece again to confirm that there were no mistakes, and then he set a positioning point on the side of the crack in the workpiece, and let Master Xu's people drill holes in these two points.

After the hole was drilled, He Xiaojun personally took action, using the simple lathe in the station repair workshop to match two tightly fitting pins, forcing them into the two holes, and then welding the two pins to the outer envelope of the hook.

After this step, He Xiaojun's repair work has been completed, and he motioned to the stationmaster of the railway station who had been beside him, and asked him to take this workpiece to do a load test to test the tensile strength of the hook.

With a nervous mood, he commanded his subordinates to do a load test, and after confirming that the hook had met the requirements for use, the stationmaster put down the heart that had been hanging for a long time, and quickly stepped forward to grab He Xiaojun, who had washed his hands and was standing aside, and thanked him repeatedly.

The stationmaster said to He Xiaojun that the help he helped today allowed the train to operate as usual, and created at least more than 10,000 yuan of value for the station and the board of directors of the train, so he asked He Xiaojun to report the remuneration for his work and let him pay it to the board of directors.

He Xiaojun told the stationmaster that he was greedy for today's arrival and action, just to help his friend Technician Xu, and it didn't cost him much work, so there was no need to talk about any remuneration.

How can the webmaster be willing? Busy saying that He Xiaojun's favor was too big and too timely, otherwise, they don't know how big their losses were?

Because, if this piece is not repaired well, at least one carriage will not function normally, so that a quarter of the amount of cars per trip will be reduced. Moreover, if you purchase this piece from Hong Kong recently, under the traffic conditions at that time, you will also see the enthusiasm of the stationmaster, a look of unwillingness to be a group if He Xiaojun does not want to be paid, He Xiaojun, who was not mentally prepared in this regard, thought after a while: Since it can no longer be shirked depending on the situation, let the station have some symbolic remuneration.

Somehow, He Xiaojun suddenly remembered the thick steel plate in the open air that was so rusted that it was already unbearable, and he couldn't help but move in his heart, and he asked the stationmaster: Can you give him that rusted steel plate as a reward for this time?

In fact, He Xiaojun didn't think of the use of the steel plate at this time, but he thought of the shortage of steel in that era, and the steel plate was a waste at the station, so it was better to give it to him, a person who is proficient in machinery, maybe it will be useful in the future, and it will be wasted here?

When He Xiaojun inspected the steel plate just now, the stationmaster was also beside him, so he also knew that the steel plate was useless. Useless things, at most, are sold as scrap products to the furnace of iron, which is not worth a few dollars, since He Xiaojun is useful, of course there is no problem in sending him.

Even He Xiaojun had already asked for a steel plate, but the stationmaster still felt that compared to He Xiaojun's help, this useless steel plate was far from his remuneration. So, the stationmaster proposed to pay He Xiaojun another fifty yuan on the spot.

He Xiaojun's behavior today, in his previous life, was called "speculation". It is to rely on technology to work for some counterpart units in his spare time and reap remuneration.

Since it is the wages earned by his own technology and labor, and his own labor has indeed recovered a big loss for the other party, it is also a matter of course to collect this hard money, so He Xiaojun was no longer polite, and took the remuneration he deserved from the stationmaster.

Of course, He Xiaojun, who received the money, did not forget the Xu technician who worked hard with him just now, and the people from the maintenance team of their station, he asked Xu technician to call all of them, saying that he was going to invite this group of people to supper.
