Background
The stamping processing is a processing mode that the plate material is directly pressed in a positioning die and deformed or separated by the power of conventional or special stamping equipment. The wedge type stamping is one of a plurality of stamping methods, and is to drive a wedge block which is obliquely arranged and a punch which is arranged on the wedge block to move through a pressure device so as to realize the pressure forming of a metal material, and the wedge type stamping can realize synchronous stamping of a plurality of wedge blocks and punches by only using a group of pressing structures, so that stamping and forming in a plurality of directions are realized.
For example, in the case of multi-directional punching of the side wall of a cylindrical member, for saving the process, cam type punching may be used, and multi-station punching may be performed on the side wall of the cylindrical member. And during processing, the barrel part is usually placed on a columnar positioning die, then the punch heads on the wedge blocks are utilized to move simultaneously for stamping, a plurality of forming holes are processed on the side wall of the barrel part, but because gaps exist between the punch heads and blanking die holes on the positioning die, when materials are blanked, the materials at the edges of the blanked forming holes on the parts are influenced by extrusion of the punch heads, deformation in the extrusion direction of the punch heads can be generated in the gaps, the deformation can extend into the blanking die holes in the positioning die and form burrs, and when the parts are taken out upwards, the burrs of the parts and the inner walls of the blanking die holes form mutual interference to prevent the parts from being taken out upwards, and if the parts are taken out forcibly, the burrs of the parts can scratch the outer walls of the positioning die to influence the service life of the positioning die.
In order to avoid the influence of the burrs on the taking out of the part, a burr pressing structure can be added in the positioning die to reversely press the burrs in the prior art, after the blanking is completed and the punch is reset, the burr pressing structure is utilized to reversely press the forming hole part, the burrs at the edge of the forming hole are pressed into the forming hole of the part, the burrs are bent and deformed into the forming hole of the part, and therefore the burrs are separated from the blanking die hole of the positioning die, and the burrs are prevented from interfering the positioning die.
When the part raw material is made of soft materials (such as aluminum, copper and the like), burrs formed during blanking are larger due to easier deformation of the material, and when the burr pressing structure presses the burrs back into the part forming hole, the burrs entering the forming hole form reverse extrusion on the part forming hole due to the fact that the burrs are positioned between the burr pressing structure and the inner wall of the part forming hole, so that the material in the inner wall area of the part forming hole is extruded and deformed to generate internal stress, and finally the quality of the part forming hole can be affected.
