Description
Technical field
The invention belongs to steelplate punching shearing technique field, Shearing Blade is punched the present invention relates to one kind.
Background technology
In recent years, developing rapidly with auto industry, environmental protection progressively turns into the development master of each cart enterprise now with safety
Topic, in order to solve automotive light weight technology and improve the technical contradiction of security, in terms of automobile steel, high intensity and unimach
Plate has turned into the direction that major scientific research institutions, automobile manufacturing enterprise and steel production enterprise are made joint efforts.
But in vehicle cladding element punching forming process, high intensity and ultrahigh-strength steel plates are on sheared edge or punching side
Inevitable fracture phenomena can occur for position.Research shows that the main cause of sheared edge or punching edge punching press rupture is
Because the surface quality for being punched edge is poor, the sensitiveness for micro-crack is stronger.And tradition punching Shearing Blade, it can only realize
Single cuts function, it is impossible to which solution cuts the problem of surface quality is poor, reduces the punch forming rate of part, causing need not
The economic loss wanted.So an important method for improving punch forming rate is exactly to obtain the steel plate with surface is well cut,
Therefore develop it is a kind of can and meanwhile realize cut and continuous processing cut surface punching Shearing Blade it is significant.
The content of the invention
According to tradition punching set forth above or Shearing Blade can only realize it is single cut to handle cut the skills such as surface
Art problem, and provide it is a kind of can be while realizing the shearing of automobile stamping sheet material or punching and realizing that synchronization process cuts surface one
A kind of punching Shearing Blade of body.The present invention on punching shearing edge top mainly by setting reconditioning face to realize that bottom is rushed
Cutting of the shearing edge to sheet metal is cut out, top reconditioning is carried out in face of the sheared edge of sheet metal or the mat surface on punching side
Frustrate it is flat or it is secondary it is trickle strike off cutting, so that it is guaranteed that shearing or being punched side there is excellent surface.
The technological means that the present invention is used is as follows：
One kind punching Shearing Blade, including punching shearing work portion and the punching in the punching shearing work portion are cut
