AI Technical Summary
Technical Problem
Existing punch and die turning methods cannot guarantee the size and shape of the turned hole, resulting in a flared hole shape and diameter, increasing the grinding process and workflow, and failing to meet the contour requirements.
Method used
The device employs a turning device, which includes an upper die assembly and a lower die assembly. The pressure block and the punch work together to limit the movement, and the internal release pressure is applied after turning the hole to ensure the consistency of the hole size and shape.
Benefits of technology
It ensures the size and shape of the holes, reduces processes, lowers production costs and time, and improves production efficiency. It is suitable for punch presses of different tonnages and metal materials.
