At the age of 28, he became a senior technician, at the age of 33, he was treated as an expert with special government allowance from the State Council, and at the age of 37, he became the chief expert of the group... From a bench worker, he grew into a versatile technical talent integrating various skills such as production, design, modeling, and assembly, Zheng Zhiming never stopped pursuing technology.
Accumulate over time to improve skills
In 1997, Zheng Zhiming joined Guangxi Automobile Group Co., Ltd. and began his apprenticeship as a fitter.
Zheng Zhiming is the first to arrive at the workshop and the last to leave work almost every day. In the process of daily sharpening, his skills have become perfect. He has become a versatile expert integrating skills such as turning, planing, welding, milling, and has practiced a unique skill - manually filing the plane, which can control the size of parts within 0.005mm; The position error of manual marking and drilling can be controlled within 0.04mm, which is the highest level of the same type of work in China.
In 2005, as a fitter, Zheng Zhiming became a senior technician of the enterprise. Since then, he did not stop. He took the time to learn UG 3D modeling by himself. In his spare time, he also asked someone for advice on motor revolution, torque, mechanical power and other aspects.
In this way, Zheng Zhiming learned as he worked, and his work was not limited to bench work. He became a capable person who was "proficient in all 18 kinds of martial arts". In 2014, he became the group's chief expert. In the same year, the national skill master studio named after Zheng Zhiming was founded.
Today, Zheng Zhiming is in the tooling workshop of the manufacturing engineering department of Guangxi Automobile Group Liuzhou Wuling Automobile Industry Co., Ltd., which is mainly responsible for manufacturing equipment for producing automobile parts. He has also become a robot equipment designer and manufacturer.
Not afraid to challenge independent research and development
With the development of the automobile industry, the production equipment of parts is also constantly upgraded. Every time the factory develops and designs new equipment, Zheng Zhiming can be seen.
In 2017, the company's chassis factory needs to manufacture an automatic welding production line for the rear axle housing. The production line is composed of a variety of complex equipment, such as air tightness detection, hydraulic straightening, machining, robot workstation, special girth welding machine, etc. The automation degree is required to reach more than 80%.
Zheng Zhiming and the team have reviewed, optimized, discussed and verified for many times, and finally came up with the overall digital model and scheme of the automated production line to successfully complete the task. After the implementation of the project, the automatic production of rear axle assembly is basically realized throughout the line. After the whole line is put into production, the labor cost can be saved by 300000 yuan every year, and the output remains unchanged. At present, this production line is the only domestic self-developed mini car automatic rear axle housing welding production line, filling the gap in the domestic automatic rear axle housing welding production line.
Recently, Zheng Zhiming has started another challenging work, to renovate the old equipment with complex working conditions in a short time and transform it into a production line for manufacturing new energy vehicles. In the face of new challenges, he became more and more brave.
Selfless dedication
On February 14 this year, during the COVID-19 epidemic, Zheng Zhiming received a request from SAIC GM Wuling for help: the mask production line was short of discharge components and could not operate normally.
Without saying a word, Zheng Zhiming immediately arranged more than 10 employees to produce the discharging components urgently. Due to the epidemic situation, the procurement of aluminum alloy materials was difficult at the beginning of production. Zheng Zhiming made phone calls from house to house and begged for support from suppliers, finally solving the problem of aluminum alloy material supply.
Since then, Zheng Zhiming has come to the workshop early every day and led the team to work hard day and night to complete a total of 14 sets of 7 mask production lines. Zheng Zhiming does all kinds of work, such as turning, milling, clamping and welding. He works overtime every day. After working for more than ten hours a day, he was too tired to straighten up.
Through the joint efforts of him and his colleagues, he successfully ensured that SAIC GM Wuling produced the first batch of masks at the fastest speed, and exported mask machines with a record of 76 hours, greatly improving the production efficiency of masks.
A single tree does not make a forest, and a single flower does not make a spring. Zheng Zhiming has been working in the production line for a long time. He has grown from an ordinary fitter to the leader of the national skill master studio. While working hard, he has also brought many apprentices to impart skills to young people without reservation.
"If we can bring out excellent apprentices, it means that our master is also excellent." Zheng Zhiming hopes to train more highly skilled talents for Guangxi automobile manufacturing industry and even for "China Intelligent Manufacturing" through mentoring.
