Big Country Intelligent Manufacturing

Fatty Zhang Gui, Xiao Guohong, Wang Qiang and Zhang Lin and other young employees chose to stay in Yiming Company to work hard after careful consideration.The fat man smiled and said to Sister Han: "Hehe...I'm relatively young anyway, and the welfare house is not my share, so I might as well stay in Yiming's company and follow Mr. Xu! He won't treat me badly!"

Ma Jimin and a group of old workers over 50 years old had the same imagination as Sister Han, and they stayed without thinking.Liu Yangde's attitude was the most determined, and he said to Sister Han excitedly: "Old Han! My two sons are eating together under Mr. Xu's hands. How can I leave Yiming Company ungratefully?"

According to some statistics, only a dozen middle-aged mechanics in their forties chose to report back and wait for the notice of placement from Nan'an Textile Group.Li Quan is naturally among these people.For the housing and other benefits he had already divided up, he had no choice but to leave, and would work in Yiming's company in his spare time to earn money.

"Well... it's pretty good, the key personnel have not changed much, just a simple adjustment!"

After seeing the statistical report sent by Sister Han, Xu Zhenming nodded in satisfaction.

He instructed Sister Han to immediately prepare to sign a formal labor contract with the group of old colleagues who stayed behind, and all those who should buy endowment insurance should complete the formalities immediately.Old colleagues choose to trust him, and he will not let them down!

After arranging these things, Xu Zhenming is ready to start arranging the project of tackling the rolling computer embroidery machine.He is relatively new to this subject and has never seen this product before.

Compared with the computer cutting machine and the computer embroidery machine, the rolling computer embroidery machine is a combination of these two products.How to combine the working methods of these two devices must be planned carefully.

The main personnel participating in this project are the team led by Sun Chao from the technical department and a small team led by Wang Guoyou from the product division.

Xu Zhenming is the leader of this project, mainly responsible for electrical automation and product process design.He used CAD software to draw some programmatic technical materials such as a conceptual diagram of equipment and a flowchart of equipment automation control.Then, he held the first technical seminar in the conference room on the third floor.

"Dear colleagues! The customer's request is to embroider on silk and satin. The length of the pattern may exceed 10 meters, and the width should be close to about 1.4 meters! If this is the case, ordinary computerized embroidery machines cannot accomplish this task!"

After looking at the technicians attending the meeting, Xu Zhenming introduced the needs of the users of the roller-type computerized embroidery machine to everyone.

The function of this kind of intelligent equipment must meet the continuous embroidery of long patterns on silk and satin. Even the working range of a 2200*1800 computer cutting machine cannot meet the needs of customers.

"So we have to design double rollers to roll the satin back and forth so that the head of the embroidery machine can embroider on the satin!"

At this time, Wang Guoyou understood the principle of Xu Zhenming's drawing of the schematic and was excited to speak first.

Sun Chao frowned, did not speak at this time, nodded thoughtfully.

"The double-roller rolls and curls the silk back and forth, and the tension problem must be solved, otherwise it will deform the customer's silk!"

"The work surface should be fixed, and the head of the embroidery machine should be able to move freely on the work surface!"

"Can it work in the same way as a roller plotter? Then there is no need for a work surface!"

"Definitely not! The plotter draws according to the dot matrix method, and the computer embroidery must be continuous embroidery!"

After listening to the customer needs introduced by Xu Zhenming, the technicians participating in the meeting all spoke and expressed their thoughts.

Among them, some people's ideas are the same as Xu Zhenming's conceptual diagram; some people's ideas are quite different.These people are also discussing with each other, constantly proposing ideas and ideas, and then constantly denying immature ideas.

After some discussion, everyone's opinions were gradually unified, and the conclusions reached were very similar to the schematic diagram sketched by Xu Zhenming.

"The plan proposed by Mr. Xu is more scientific, the function meets the needs of the customer, and the structure is relatively simple!" At the end of the day, all of them were talking with flushed faces, looking quite excited.

Looking at everyone’s expressions, Sun Chao, who had not spoken all the time, said slowly: “My colleagues, I think Mr. Xu’s plan is more realistic! His plan is actually a computer cutting machine with a set of sheets added. Tight roller system!"

After much deliberation, he finally figured out the original intention of Xu Zhenming's design.After comparing his own ideas, he thought that Xu Zhenming's schematic diagram was simpler and more practical than his own design, so he stood up and expressed his opinion.

"Assistant Sun is right! The drum-type computerized embroidery machine I designed is based on a computerized cutting machine. The cutting head is removed and replaced with the 15-needle head of the computerized embroidery machine. Then a set of satin curling rollers is added. Dao, responsible for moving the silk and satin back and forth on the worktable for the embroidery machine head to do embroidery..."

At this time, Xu Zhenming saw that everyone had finished the discussion and began to explain his initial idea of ​​designing this kind of equipment to everyone.

His method should not be great for Yiming's current manufacturing level.In all cases, the manufacturing, assembling and debugging of this drum-type computerized embroidery machine is not so easy to complete.

Because the work to be embroidered is silk and satin, the friction, tension and curling speed of the curling roller table are relatively high.Any problem in any link will destroy the silk.

Not only that, this drum-type computerized embroidery machine is a typical four-axis linkage machine tool, and the adjustment and control of the four-axis linkage is more complicated.At present, apart from Yiming, none of the domestic companies can develop such a CNC control system with complex algorithms!

In this regard, Sun Chao, Wang Guoyou and others have insufficient knowledge and cannot understand the difficulty of four-axis linkage control.

"...The head of the computerized rust machine moves in the three directions of X-axis, Y-axis and Z-axis to embroider patterns on the silk! At the same time, the silk and satin should move slowly under the traction of the curling roller to match the embroidery. The work of the nose! This working method is a real four-axis linkage! It is not a three- and a half-axis working method!"

At this time, Xu Zhenming introduced the principle knowledge of data machine tools.The two situations in the four-axis linkage system are described in detail.

At present, the domestic CNC machine tools, although there are four-axis linkage machine tools, they generally work in three-and-a-half-axis mode, and are not true four-axis linkage technology.

Four-axis linkage technology is not only difficult for the algorithm of the CNC control system, but also for the performance requirements of the machine tool.Once the cumulative error of the machine tool is relatively large, the performance of the four-axis linkage machine tool is not as good as the three-axis linkage machine tool.

This is the big thing that made Xu Zhenming a headache!
