381 Chapter 380 The first combined machine tool in China (for subscription)

"The operation sequence of the entire production line is okay! But the accuracy error is too large, and the equipment action is not uniform. The prototype of this automatic drilling and cutting production line requires major surgery!"

Seeing Sun Chao and others looking at him, Xu Zhenming frowned and said.

Immediately, he came to the rectangular tube that had finished cutting, pointed to the holes that had been drilled, and said, "You all come and see, are these holes offset as a whole?"

Everyone gathered around to watch.

"Why can't I see the error?"

"I didn't see it either. You have to measure it with a gage to know!"

"Actually, there is no error. The CNC programming of drilling is made by me. There is no error in theory, and the actual machining error will not exceed 0.05 mm, right?"

Sun Chao and others all looked blank.

Fortunately, there was a quality inspector nearby, and they asked the quality inspector to immediately inspect the workpiece that had just completed the job.The quality inspector in charge of quality inspection brought various instruments and meters and began to check.

"Report to Mr. Xu and Assistant Sun! The holes on the left and right sides of the workpiece have shifted upwards by about 3 mm!

Before long, quality inspectors came to report the inspection results.

After getting this information, Sun Chao and others were even more surprised, "How could this failure occur?"

At this time, Xu Zhenming pointed to the connection between the holding and clamping robot and the workstation, "Every time the holding and clamping robot is started, there must be a calibration reference position. Otherwise, the error just now will occur! "

"Oh..." Sun Chao and the others suddenly realized.

This problem is easy to solve, just add a reference calibration device.It's just that the problem of inconsistent equipment movements is a bit difficult to solve. It needs to be adjusted one process at a time to solve the problem.And Sun Chao's technical team has to be responsible for another project, I am afraid that the clone is lacking!

Thinking of this, Sun Chao smiled bitterly and asked Xu Zhenming for instructions: "Mr. Xu! Can this project be suspended for a period of time? The technical team of our project team is in charge of the clothing computer cutting project. Time is too tight."

The prototype of the garment computer cutting machine has been tested several times, and a brand-new No. 2 test sample machine is being manufactured.Once all the spare parts are manufactured, Sun Chao and others will go all out to debug the equipment.

According to Xu Zhenming's vision, if time is not enough, this clothing computer cutting bed will be displayed at the trade fair on October 25 in Wenrui City.

Sun Chao's proposal was reasonable, but Xu Zhenming didn't think so.

He said with a serious expression: "The research and development work of this production line must not be stopped, and the production line must be debugged while the iron is hot. The main equipment has been finalized, why should it be suspended?"

"This..." Sun Chao looked embarrassed.

Xu Zhenming glanced at him, then pointed to Zheng Cheng beside him and said: "You hand over the situation of this project to Minister Zheng, and Minister Zheng's team is ready to take over this project!"

"Yes!" Sun Chao nodded.

Immediately, Xu Zhenming instructed both of them: “Immediately disassemble and pack this production line, and transport it to the large-scale riveting and welding parts manufacturing base for debugging. Once the debugging is successful, it can be directly delivered to the large-scale riveting and welding parts manufacturing base for trial operation and put into use! "

This arrangement is the rule of Yiming Group: All newly developed new products and new production lines must be tried out for a period of time to test the quality and performance of the products.

Zheng Cheng and Sun Chao received the order and immediately led people to start the transfer of technical information and other procedures.Xu Zhenming followed along, and pointed out all the minor problems he found.

More than ten days later, Xu Zhenming was receiving Sister Han in the office.

"Mr. Xu! We have completed the bid for the resettlement housing project in Nan'an Economic Development Zone. Please review and approve it!" Sister Han handed Xu Zhenming two thick bids.

The bidding documents for the housing construction project are very professional, and Xu Zhenming cannot completely figure it out.

He just looked through the terms of the preferential conditions and the description of the project offsets in the commercial tender, and saw that the content he requested was all there, so he signed his name on the power of attorney.

"How are you preparing the project plan for the joint venture of the Xiangnan Electric Factory?" He asked Sister Han while signing.

Sister Han said with a smile: "Mr. Xu! We are glue-binding the two project plans for this project. Once glue-packing is completed, they will be sent to your office!"

"That's not necessary! You can directly mail the project plan to the Xiangnan Electric Factory. Let the other party be psychologically prepared!" Xu Zhenming thought for a moment before making a decision.

He believes that this project will not be negotiated so quickly, and it will take many rounds of negotiations with the Shonan Electric Factory to produce results.Therefore, the first project plan can only be regarded as an intention.

After completing the formalities, Sister Han was ready to get up and leave.At this time, Xu Zhenming gave another order, "You can contact Song Lang and invite him to our group company at the end of October to participate in the second-generation servo motor press conference."

"Yes! Mr. Xu!" Sister Han nodded before leaving.

Since deciding on the model of the second-generation servo motor, Xu Zhenming has arranged the production line of the servo motor laboratory and is fully producing this product for the press conference at the end of October.

Because the enameled wire production line and the permanent magnet production line are undergoing intelligent transformation, the output of the second-generation servo motor cannot be raised, so I had to do so.

When Xu Zhenming was in a daze, thinking about the problem, the phone rang on the desk suddenly.

"Report to Mr. Xu! The automatic drilling and blanking production line has been transformed and debugged and will be ready for trial production this afternoon. Are you free to guide the work?"

After the call was connected, Zheng Cheng reported the situation on the phone with a smile.

This news slightly exceeded Xu Zhenming's expectations.

He originally thought that the clothing computer cutting machine would complete the debugging work ahead of time.But I did not expect that the automatic drilling and blanking production line was successfully debugged in advance.This production line is very important and can improve the production efficiency of most equipment of Yiming Group.

Thinking of this, he smiled and said: "I'll be here soon!"

Before long, wearing a safety helmet, he moved into the courtyard of the large-scale riveting and welding parts manufacturing base and came to the gate of a three-story building.

This three-story building is the test workshop of the automatic drilling and cutting production line.Chen Dengliang, Shi Fan and others were standing outside the gate waiting for Xu Zhenming's arrival.

"How about? Has it been put into production just now?" Xu Zhenming asked Chen Dengliang with a smile just after getting off the car.

"Report to Mr. Xu! We have tested it with 100*60*6 rectangular steel pipes. The drilling is very fast and the cutting speed is very fast! Hey...this production line is too advanced!" Chen Dengliang has not had time to answer Xu Zhenming's Asking questions, Shi Fan, who was beside him, told Xu Zhenming the result of the experiment with a silly smile.

When Xu Zhenming heard the words, he smiled and nodded: "Well! You guys did a good job!"

He knew that this day would come true sooner or later, but he didn't expect it to come so soon.Afterwards, he followed Chen Dengliang and Shi Fan in the workshop.

In the production workshop, crane workers are hoisting a 100*60*6 rectangular steel pipe, and put the 12-meter-long welded steel pipe on the transportation roller table at the head of the production line.

In order to increase the efficiency of the production line, Zheng Cheng's team increased the transport rollers at both ends of the production line by about 30 meters.In this way, the loading operator and the unloading operator do not have to wait for the production line, and can continuously load and drop the workpiece.

Zheng Cheng also improved the control room of the entire production line and placed it on the top of the first floor of the workshop and near the passageway on the second floor.The central control room is made of steel and glass, and the operator can see the running status of the entire production line through the glass window.

This design is very reasonable and meets the needs of the actual production process.Moreover, the entire production line, except for the hoisting operators for loading and unloading, only needs one main operator to control it, and the labor cost is particularly low.

Seeing this scene, Xu Zhenming smiled and nodded, and asked Chen Dengliang who was standing beside him sideways."How about the accuracy of workpiece machining?"

"Report to Mr. Xu! We have just checked, and the dimensional tolerance of the computer embroidery machine's support column is completely within the technical requirements!" At this time, a quality inspector handed the inspection record to Xu Zhenming.

Xu Zhenming did not have time to pay attention to these details. Instead, he asked Chen Dengliang: "Director Chen, how many man-hours did this computer embroidery machine support column originally take? How many man-hours does it take now? Have you made a comparison?"

"Report to Mr. Xu! I have already compared it. When the computer embroidery support column was originally made, it required cutting, scribing, drilling and other processes, which took about an hour. Now bang! Hey... it only takes four minutes! "Chen Dengliang smiled a few times after hearing the words.

"The efficiency has been increased by fifteen times. If it is changed to dual-track processing, the efficiency can be increased to about 30 times. The function of the automatic drilling and blanking production line is really powerful!"

"Then you need to say? The fully automatic production line is so powerful!"

"Our large-scale riveting and welding parts manufacturing base only needs to add two such production lines, and the steel pipe blanking workshop can be cancelled!"

After listening to Chen Dengliang's introduction, Shi Fan and a group of college students who came to the internship were extremely excited to discuss.

At this time, Xu Zhenming waved to them, "Go! Let's take a tour together. Let Minister Zheng introduce the principle of this CNC modular machine tool to everyone!"

"Yes!" Everyone nodded with a smile.

Soon after, they followed Zheng Cheng and moved slowly along the long automatic drilling and cutting production line.

"Mr. Xu and colleagues, this automatic drilling and cutting production line is actually a CNC modular machine tool. This machine tool integrates CNC drilling machines, CNC hydraulic punching machines, CNC sawing machines, clamping robots, automatic centering devices... etc. , A series of intelligent numerical control equipment. Everyone knows that the more automatic control units, the more difficult the algorithm of the control system..."

While walking, Zheng Cheng introduced the principle and performance of each split device.These equipments are manufactured by Yiming Group itself, and some adjustments have been made in the way of working and installation, which are different from general equipment.

He also told everyone, "The core of this machine tool is the PID automatic control system. The core code, data model and core algorithm of this system are all provided by Mr. Xu!"

"Oh…"

Everyone looked at Xu Zhenming upon hearing this.
