participated in 12 major technical transformation projects, obtained 28 utility model patents, and won the "Weihai Science and Technology Award" and the "Second Prize for Shandong Employees' Outstanding Technological Innovation Achievements"... This dazzling resume belongs to Shandong Li Xuchun, CNC machine tool engineer of Weida Machinery Co., Ltd.
From an ordinary worker to an "innovator" who uses research and development results to help the company strive for championship manufacturing, Li Xuchun has been rooted in the front line for 12 years, conducting continuous and serious analysis, research and innovation of equipment and products on the production line, accumulating direct creation for the company. The economic benefit is more than 20 million yuan.
"The main process of the electric hammer chuck requires that the chuck runout is two wires. This is the key point. The first piece must be inspected every morning." In the production workshop of Shandong Weida Machinery Co., Ltd., Li Xuchun is demonstrating the electric hammer with his colleagues Experimental plan for hammer fixture production line. After the twenty-minute "discussion", the biggest impression Li Xuchun left on everyone was that he was "real".
Just taking the measurement of the runout of the workpiece as an example, Li Xuchun will use a coaxial instrument or three-dimensional coordinate (measuring instrument), projector and other instruments for measurement. Only when the data reaches unity will he recognize the data as accurate.
This kind of "realism" runs through every aspect of Li Xuchun's work. "My job is to arrange production plans and improve equipment technology." Speaking of his work content, Li Xuchun simply summarized it. But in fact, the production line Li Xuchun is responsible for has more than 170 pieces of equipment, involving 28 processes and 35 processes, which is by no means a simple matter.
Initially, the accuracy and processing efficiency of these products could not meet the needs of foreign customers, and the company once encountered a bottleneck when exploring overseas markets. In order to help the company build a brand in the international market and to create personal value in his position, Li Xuchun used his spare time to teach himself professional knowledge such as benchwork and machining, and tried dozens of solutions "really" before finally proposing ring gear turning. ways to improve. This improvement not only lowers the skill requirement threshold for operators, but also shortens the training cycle for new workers, improves the flexibility of product assembly, and creates direct economic benefits of more than 1.3 million yuan per year.
"Before the transformation, one tool can process 100 pieces. After the transformation, one tool can process 3,000 pieces. The service life of the tool has been increased by 30 times, and the accuracy and surface roughness have increased by more than 50%." Faced with his "work", Li Xuchun introduced proudly. And this is just a microcosm of Li Xuchun's "realistic" journey.
——Proposed a new heat treatment gripper process. Based on the original heat treatment process of the clamp jaw, the stress relief step of the clamp jaw material is added to significantly reduce the heat treatment deformation of the clamp jaw, so that the one-time pass rate of the chuck after assembly reaches more than 95%, creating direct economic benefits of more than 1.6 million yuan every year.
——Improvement of the chuck for electric grinding. Through years of practical production experience, the runout of the processed main body is guaranteed to be ≤0.03mm, while the matching gap between the jacket and the main body is reduced, creating direct economic benefits of more than 1.5 million yuan every year.
——Research on angle drill chuck. Through careful research, the threaded connection behind the drill chuck was improved to a straight handle connection, and integrated with the electric hand drill to meet the working environment requirements of the chuck turning at a vertical 90°. This project won the national utility model The patent has created direct economic benefits of more than 1.2 million yuan for the company.
Recently, Li Xuchun has set his sights on the professional electric hammer chuck series, and wants to lead his team to compete with major competing manufacturers internationally. "This electric hammer chuck project is supplied to Germany. It is a project that the company has never had before. The annual usage of this model is hundreds of thousands. It can be expanded from one point to an entire area, and the benefits created are very large. "Li Xuchun is full of confidence in the future.
Won the honorary title of "Weihai Craftsman", Li Xuchun felt that the burden on him was heavier.He said that in the future, he will pass on his experience and knowledge to more people on the basis of doing his job well, and drive more young people to take the path of becoming talents and serving the country with skills.
