Enter Sheet Metal Forming Technology, be one of company important channel of maintaining existing customer's order and the new customer order of Persisting exploitation.
Cross thin material hole flanging traditional handicraft generally by first rushing pre-hole hole flanging again, or first rush pre-hole add chamfering light
Band hole flanging the most down, during for the high-strength plate hole flanging height of slab hole flanging particularly more than 4 millimeters more than 2 times of material are thick, by biography
The flange hole technology hole flanging of system can not be successful, because the tensile strength of high-strength plate and yield strength are higher, hardness is partially hard, hole flanging height
Not only not reaching requirement, and head peak serious cracking, hole flanging once has cracking, does not highly reach requirement and be possible to send out
Torsion and the problem not reaching setting value of extrusion pressure after raw hole flanging tapping.
In order to improve production efficiency, reduce cost of stamping, control product quality, certainly will need to develop on a kind of continuous mould
