first class
"I heard that Huang Wei, a super technical expert in the aviation industry, was my master. At that moment, I felt so lucky to be the apprentice of 'Dana'. This is not a 'lucky thing' that can happen to everyone!
Before long, under the leadership of the master, Liu Jiahao (nicknamed "Jiahao") quickly became familiar with and mastered the products and related production processes produced by the welding factory, and began to assist the senior brother in the work of winding cloud lock springs.
first test
The cloud-shaped lock spring is definitely a "big" job - not only is it difficult to do and the quantity is "large", but also the material is hard and difficult to form, especially after manual winding and forming, the precision is not stable, only forming the spring body It will take more than two months.
After get off work every day, Jia Hao would puncture the blood blisters on his hands one by one, and get out of bed with his arms that he could barely lift. "At that moment, I really don't want to do it!"
He thought, if only there was an automatic machine... Before the end of this batch of work, he complained to his master Huang Wei, but the master only told him, "If you feel too tired, just use your own brain and think about it. solution, solution."
one practice
As he learned more and more about springs, he discovered that if the methods of hand winding and machine winding were combined, could cloud springs be formed on the machine?
Under the guidance of the master, a prototype of the tire was gradually formed: the hand-wound tool was changed to a circular upper die, the tooling for forming the spring body was changed to a circular lower die, and the upper and lower die were installed on the two motors. It can automatically rotate the formed spring body.
An idea has to be practiced. At the beginning, although the wire can come out of the wire hole, it cannot reach the proper position of the lower die. He added a positive guide to the lower die so that the wire could reach the correct position of the lower die.heavy fuel engine
There are always new problems on the road of innovation. The formed spring body is only half, and the other half will cause the steel wire to "bounce" directly from the groove of the tire when the steel wire is cut. He used his brain again to install a wire pressing bar on the lower die. When cutting the wire, let it press the wire into the groove, and the other half of the spring body can be formed smoothly.
"In fact, there is no shortage of innovative ideas in the production line, but what is lacking is the actual action that is actually put into practice." He said with emotion, feeling the joy of success.
keep improving
Faced with the second problem that comes with it: after the automatic forming of the spring body, it is stuck on the lower mold and cannot fall off smoothly, and naturally the next cloud-shaped lock spring cannot be smoothly formed.target drone
He felt that he had to find a way to make it unload automatically to form a complete closed loop of the automated process.
In the continuous improvement and experimentation, this innovative small device can now be used in the production line.
"A small innovative idea has liberated both hands." Standing in front of the equipment he designed and manufactured, Jiahao was a little proud.
successfully implemented
The successful implementation of the project provides a new efficient processing mode based on multi-station CNC spring winding machine to automatically process cloud-shaped lock springs for the aviation manufacturing industry to produce such standard springs.
Today, after using this innovative device to numerically coil springs, it can produce 600 pieces per hour, greatly improving production efficiency and ensuring product quality.
