Description
Technical field
The present invention relates to Punching Technology field more particularly to a kind of reversed blanking die and its punch press process methods.
Background technology
Punching is a kind of common metal working process.In blanking process, in the lower surface of blanking part often with vertical
To burr, the appearance and quality of the product seriously affected.The height of burr, the material for depending mainly on the size of work metal,
Intensity, thickness etc..It is fixed in work metal, also have with the blade clearance of mold, the abrasion etc. of upper and lower mould cutting edge
Prodigious relationship.But even if by blade clearance, the abrasion of upper and lower mould cutting edge improve, although can be the height limitation of burr
To a certain minimum value, but can not possibly completely eliminate.
Therefore a kind of impulse- free robustness punching process of demand is suitable for single-stroke mould.The technique makes sheet metal after punching,
It no longer needs to carry out any chamfering and repaiies other additional works such as burr, you can realize impulse- free robustness punching.
Invention content
In order to solve the above technical problems, the present invention provides a kind of reversed blanking die and its punch press process method, for
Deficiency in the prior art coordinates reversed punching in such a way that positive negative clearance is not exclusively punched, solve existing way into
Row punching, the problem of the lower surface of blanking part carries longitudinal burr.
In order to achieve the above objectives, technical scheme is as follows：A kind of reversed blanking die, including positive blanking punch,
