When NC apprentices have a task system

Chapter 104 Super Mold Repair Machine

"XCMG, this is the mold sent by the customer, and they said they want us to repair it."

Chen Zhengxin said.

Mold repair?

Xu Yang frowned upon hearing this.

This was the first time Xu Yang had heard of it, and he immediately became curious.

Thinking of this, Xu Yang leaned over to the mold and looked at it carefully.

Although Xu Yang has never been in contact with mold repair, he probably knows that this is a set of plastic molds. From the surface, there is no major problem, but the problems with the mold are usually internal problems, because this is the more difficult problem.

"Chen Gong, what's the problem?" Xu Yang asked.

Chen Zhengxin frowned, and said with a look of embarrassment: "It's not a big problem, it's just that the mold is strained. But this manufacturer makes products for the West Island countries, which belong to foreign trade exports, and are relatively strict. If you follow the usual methods to repair It may be difficult to pass the test. But our factory has limited equipment, I think we can only send it out, and if this is the case, our profit will be gone, and we will basically lose money."

"I disagreed at the beginning. It is the most difficult to make molds for foreign trade export to receive orders from this manufacturer. In addition, this time, we have repaired them for no less than five or six times. Repair until they are satisfied, otherwise the final payment for this set of molds will always be in arrears."

"Oh."

Xu Yang frowned upon hearing this.

He also heard what Chen Zhengxin said, which meant that this set of molds belonged to the type of foreign trade export, and had been repaired several times, but the other party was not satisfied, and had been in arrears with the final payment for the molds.

Although Xu Yang doesn't know much about mold repair, he also knows that it involves high standards and strict requirements when it comes to foreign trade exports.

"Well, Mr. Chen, I'm not good at mold repair, so let me tell you your opinion first." Xu Yang said with a smile.

Chen Zheng was stunned for a moment, then glanced at Xu Yang thoughtfully, and secretly sighed in his heart:

"What a humble XCMG, a role model for us!"

Because he has seen Xu Yang's deep cavity boring technology in the past few days, Chen Zhengxin has long regarded Xu Yang as a CNC master on the same level as himself, so when he heard Xu Yang say that he is not good at mold repair, he subconsciously I thought it was Xu Yang who was pretending to be modest, or that he wanted to test his understanding of Mr. Chen's understanding of mold repair, so as to give him some advice?
The more Chen Zhengxin thought about it, the more he felt that his judgment was correct, so he took a deep breath and expressed his opinion.

"Actually, mold repair is just that..."

At this moment, the sound of the system sounded.

"Ding! Trigger the task of NPC CNC master Chen Zhengxin: listen carefully to Chen Zhengxin's explanation on repairing molds. Rewards for completing the task: money +100! Experience +100! Favorability +5! System fault repair +0.1%! There is a certain chance to get a super mold repair machine! "

"Fog grass!"

"Another super series?"

Xu Yang was overjoyed, and his heart was filled with excitement.

You must know that the super boring anti-vibration knife last time was an old bull. It directly achieved the perfect deep cavity boring processing, and it is even more powerful than the imported boring tools from West Island. It can be said that it has thrown them away several times street.

Next, Xu Yang listened carefully to Chen Zhengxin's explanation on mold restoration.

It turns out that molds play an extremely important role in modern industry, and its quality directly determines the quality of products.Improving the service life and precision of the mold and shortening the manufacturing cycle of the mold are technical problems that many companies need to solve urgently. Mold repair issues.

First, argon arc welding repair.

Welding is carried out by using the burning arc between the continuously fed welding wire and the workpiece as the heat source, and the gas shielded arc ejected from the torch nozzle.

Due to its low price, it is widely used for mold repair welding, but its disadvantage is that the welding heat-affected area is large and the solder joints are large.

Second, mold repair machine repair.

It uses the principle of high-frequency electric spark discharge to repair the surface defects and wear of the metal mold by athermal surfacing welding on the workpiece. The main feature is that the heat-affected area is small, and the mold will not be deformed after repairing, no annealing, no stress concentration, and no Cracks appear to ensure the "integrity" of the mold: it can also be used to strengthen the surface of the mold workpiece to meet the performance requirements of the mold such as wear resistance, heat resistance, and corrosion resistance, and the cost is high.

Third, brush plating repair.

The brush plating technology uses a special DC power supply device. When working, the power supply component is adjusted to a suitable voltage, and the plating pen soaked in the plating solution is in contact with the surface of the repaired workpiece at a certain relative speed. Under the action of the electric field force, the metal ions diffuse to the surface of the workpiece, and obtain electrons on the surface to be reduced to metal atoms, so that these metal atoms deposit and crystallize to form a coating, that is, to obtain what is required on the working surface of the repaired plastic mold cavity. uniform deposition layer.

Fourth, laser surfacing repair.

Laser welding is welding performed by using a laser beam focused by a high-power coherent monochromatic photon flow as a heat source.This welding method usually has continuous power laser welding and pulsed power laser welding.

Fifth, laser cladding technology.

Laser surface cladding technology is to rapidly heat and melt the alloy powder or ceramic powder and the surface of the substrate under the action of the laser beam. After the beam is removed, self-excited cooling forms a surface coating with a very low dilution rate and a metallurgical bond with the substrate material. , thereby significantly improving the substrate surface wear resistance, corrosion resistance, heat resistance, oxidation resistance and electrical properties of a surface strengthening method.

……

"XCMG, there are generally the above methods for mold repair. However, this customer is quite tricky. It is estimated that the only way to repair the mold is to use a mold repair machine, but the cost is too high and you need to pay for it."

After a while, Chen Zhengxin finally finished speaking.

"Ah."

Xu Yang nodded thoughtfully.

Chen Zhengxin is worthy of being a master of CNC moulds. He has a good understanding of mold repair and basically thought of all the methods.

Xu Yang is a layman, so naturally he dare not talk nonsense, all he has to do is to see the system's reaction.

At this moment, the sound of the system sounded.

"Ding! NPC CNC master Chen Zhengxin's mission is completed: money +100! Experience +100! System fault repair +0.1%! Congratulations to the host for successfully obtaining the super mold repair machine."

yeah!
Mission accomplished.

Now it's all right, the super mold repair machine is here, and my mother no longer has to worry about the problem of my mold repair.

But what is the performance of this super mold repair machine?Will there be limitations?
After some excitement, Xu Yang quickly calmed down and asked:

"System, about the super mold repair machine?"

"Ding! The super mold repair machine is a virtual product of the super series that can repair molds. It can only be used if the host's level reaches LV7 CNC mechanic master level or above, and the number of times of use will increase with the level. In this way, the host The professional level is Lv7, that is, it can be used 7 times, and so on, the higher the level, the more times."

Fog grass!

This super mold repair machine really has limitations. Xu Yang is glad that he just met the minimum standard, otherwise he would not be able to use it even if he got it, staring blankly.

However, virtual products are not easy to display, so we have to find a way.

correct.

Xu Yang thought of the stupidest idea, that is to buy a second-hand mold repair machine and use it as a cover, so that it will be safe.

　Rejuvenating the country through industry, CNC technology!
