Recently, the epidemic has spread all over the country, entering a critical period of epidemic prevention and control. However, at the same time, the production of enterprises cannot be stopped, especially some major projects have to work overtime. How to "grasp both hands and make no mistake" in epidemic prevention production is the biggest challenge faced by many enterprises at present.
Chengdu: the production of aerospace equipment here remains unchanged
Chengdu, Sichuan, and the Seventh Research Institute of China Aerospace Hi-Tech Holding Group Co.Ltd(000901) group undertook the production of cables on rockets. The cable on the rocket is like the blood vessel on the rocket, which connects the ignition system, control system and other "organs" of the rocket and plays the role of signal transmission.
In the past few months, 13000 cables, 5000 transformers and more than 100000 bakelite products have been provided to Long March 5, Long March 7 and other launch vehicles in this workshop. But recently, there are more and more challenges to complete the production tasks on schedule.
In order to solve the logistics problems, Liu Yi, director of the Seventh Research Institute of China Aerospace Hi-Tech Holding Group Co.Ltd(000901) group and the cable workshop of Sichuan Aerospace Liaoyuan Technology Co., Ltd., specially set up five production shock teams. What kind of materials can't be in place at the moment, the commandos think of various ways to move and allocate materials.
If the materials are recovered, the production process and construction period should be scrambled. In order to ensure that various types of cables in the workshop can be produced on schedule, digital production equipment has become a magic weapon to improve production efficiency. For example, this electronic wiring screen system can improve the production efficiency of the same process by nearly 20 times.
Also in Chengdu, in another workshop of the Seventh Research Institute of China Aerospace Hi-Tech Holding Group Co.Ltd(000901) group, everyone is busy against the clock. The servo mechanism developed here is an important part of the launch vehicle control system. Generally speaking, what is built here is the "steering wheel" of the rocket.
On that day, a good news came from the inspection site of the measurement and inspection department. A key component in the servo control system - the accumulator, has made a new breakthrough in the machining accuracy of the inner surface.
The surface accuracy of the accumulator affects the working state of the servo mechanism. Before that, the qualified rate of parts processed by grinding technology can only reach 40%, and the qualified rate of this key part can be greatly improved by technicians through honing technology.
This year, they need to produce more than 2000 shells, and they are still different types. To this end, front-line technicians continue to optimize the flexible production line.
In the past, after each process of the production line was completed, a lot of metal debris would be produced, which greatly affected the production progress. Through careful consideration, Chen Fei has developed an automatic debris blowing device, which enables the whole production line to operate continuously for 24 hours even if it is unattended.
At present, the company has built 17 digital production lines. For the same production tasks, the personnel investment is only 10% of the original, but the production efficiency has been increased by three times.
[half hour observation] courage is shown in difficulties and dangers, and responsibility is shown in dangers
In the face of the current complex covid-19 pneumonia epidemic situation, epidemic prevention and control is still the top priority in the current work, but at the same time, in order to stabilize the supply chain and ensure the timely delivery of orders, people who stick to the front line of production are doing everything possible to overcome various difficulties. They are "adherents" who go through trials and hardships and wear stars and the moon. There are "glimmers" on everyone. Their energy gathered together will be a strong light for us to overcome the epidemic and start again. Let's work together to welcome the warm spring flowers.
