Description
Technical field
The present invention relates to a kind of mould；More particularly to the Re Chong centers punch die on a kind of leaf spring hot rolling production line.
Background technology
Existing changeable section plate spring production process is that other subsequent handlings, the plate spring sheets such as blanking, variable cross-section rolling, drilling exist
Need to carry out hot rolling process after the completion of blanking, to save space after the completion of rolling, plate spring sheet carries out natural cooling after piling up, treated
Drilled to after naturally cooling to normal temperature, other subsequent handlings are transferred to after the completion of drilling.Because reed cooling velocity is slower, meeting
Cause rhythm of production slack-off, influence manufacturing schedule, the artificial labor intensity that drills is big, low production efficiency, produces a large amount of waste.
The content of the invention
In order to solve the above technical problems, it is an object of the invention to：A kind of heat punching on leaf spring hot rolling production line is provided
Center punch die, it can be punched in the centre bore of the enterprising andante spring of leaf spring hot rolling production line, avoid secondary operation, improve production effect
Rate, save production cost.
The present invention is that technical scheme is used by solving its technical problem：
