Technical Field

The utility model belongs to the technical field of hardware stamping equipment technique and specifically relates to a bead cutter for five metals punching press.

Background

The hardware stamping is a process for deforming or breaking stainless steel, iron, aluminum, copper and other plates and special materials by using a punch press and a die to achieve a certain shape and size. The stamping process can be roughly divided into two major types of separation process and forming process (bending, deep drawing and forming), wherein the separation process is to separate a stamping part and a blank along a certain contour line in the stamping process, and meanwhile, the quality of the separation section of the stamping part also meets certain requirements; the forming process is to make the punching blank generate plastic deformation under the condition of not damaging, and convert the punching blank into the required finished product shape, and simultaneously meet the requirements of dimensional tolerance and the like. The edge cutting process is a stamping process which utilizes a hardware stamping die to trim the edge of the forming process to enable the edge to have a certain diameter, a certain height or a certain shape, and is finished by an edge cutter, for example, the patent with the publication number of CN207642085U and the publication date of 2018, 7 and 24 days is named as 'a stretched part edge cutter', the edge cutter realizes the edge cutting operation of a part through a stretching convex end and a stretching concave end which are connected by a sliding rod, but the distance between the stretching convex end with a cutter and the stretching concave end for placing the workpiece is too small, the workpiece needs to be manually stretched into the space between the convex end and the concave end to be taken out after the edge cutting is finished, the hand is easy to be cut, and the safety factor is not high.
