[Ten Years@Every Struggle] "Great Power Craftsman" on the pliers: Gan Dang "Wo Di" educate newcomers

Li Kaijun at work. (Data Map) Intervian

Editor's note: Every Chinese who work hard is the most beautiful struggler. It is precisely because of hundreds of millions of struggle that China is today. Ten years, pay tribute to you every struggle. Let's work together, and we will work hard to the future.

"396, 397, 398 ..." After finishing the 400th push -up, the 52 -year -old Li Kaijun slowly got up, and the large sweat was soaked in the work. 400 push -ups every morning are one of the two things he insisted on all year round, and the other is not drinking. The purpose of this is to make the movements on the hand more stable and more accurate.

Li Kaijun is the first senior expert in Jilin Province. He is currently the squad leader of FAW Foundry Co., Ltd.'s cast mold equipment plant mold manufacturing workshop. He also has a number of titles: national model models, "big country craftsmen", the winner of the Chinese skill award ... and he is more willing to call himself a car worker.

The mold is called the "mother of the industry", and the accuracy of the car mold determines the quality of the vehicle. High -end models such as Hongqi produced in FAW have a large number of key parts, many of which were born of high -precision molds made by the Likai Army.

Li Kaijun's eyes next to the platform focused on watching the workpiece that had just been grinded. "The processing accuracy of the old -style milling machine is 0.2 mm, and some CNC machine tools can be controlled to 0.03 mm." And Li Kaijun's hands can reduce the accuracy to 0.01 mm.

Higher accuracy means that it is difficult to make a more difficult job. More than ten years ago, a Canadian merchant found FAW in China and wanted to customize a set of 23 tons of car oil bottom shell molds. Its accuracy requirements were high, and they were extremely rare in China at that time. Mold manufacturing has increased great difficulty, and Li Kaijun polished for 4 months. When the completion is about to be completed, the other party suddenly put forward changes to make a large area of ​​welding on the mold. Li Kaijun and colleagues worked overtime and fought for more than 20 days to innovate five kinds of processing methods. Finally, the task was completed high -quality. Praise, and purchased an order of 8 million yuan, the company has opened up the international market.

Li Kaijun recalled that the merchant had previously found mold manufacturers in China. FAW is their "last stop". If it fails to meet the requirements of the process parameters, it will give up production in China. "Now more than 20 tons of molds are not big, we can process 60 tons." He said, robots, high -precision CNC machine tools, and the innovative results developed by the Li Kaijun team have greatly improved production efficiency and manufacturing Accuracy.

In recent years, there are countless complex molds completed by Li Kaijun. It has improved nearly 100 innovative technologies and filled a number of die -casting mold manufacturing technology. His large gearbox mid -shell mold has been highly evaluated by foreign experts, and its products are exported to the United States, Canada, Spain, Mexico and other countries and regions.

In recent years, Li Kaijun has taught technology to young people while buried his head, and has changed from "master" to "master". "There is an unwritten rule in the factory. I have to come to my training for one year for new employees to enter the factory. Learning technology and training basic skills." Li Kaijun said that he did not count the lectures, and there were more than 120 apprentices he trained.

To the proud of "Master", apprentices Zhu Weidong, Liu Yan and others won the championships in several national employee professional skills competitions, and dozens of people picked gold and silver at all levels of skill competitions.

"Wo Tu" is a WeChat name that Li Kaijun has used for many years. He is looking at the equipment that runs at a high -speed operation in the workshop. He said that in front of him, he has cultivated his "fertile soil". He has been struggling here for more than 30 years, with cultivation and gain. He also hopes to become a "fertile soil" and cultivate more skillful talents.
