Punching and trimming type single punching die for automobile brake disc brake wheel

Abstract

The invention discloses a punching and trimming type single stamping die for an automobile brake disc brake wheel, and relates to the technical field of stamping dies. The punching and trimming type single stamping die comprises an upper die base and a lower die base, an upper padding plate is installed on the lower surface of the upper die base, an upper clamping plate is installed on the lower surface of the upper padding plate, a stopping plate is arranged on the lower side of the upper clamping plate, an upper die plate is installed on the lower surface of the stopping plate, and a stamping head is further installed in the center of the upper die base. According to the punching and trimming type single stamping die, a lifting plate, a first connecting frame and a movable die are used,when the upper die base rises, the lifting plate enables a sliding rod to push the movable die, and the movable die is made to be away from the stamping head, so that the safety is higher when a worker takes a workpiece; and a second connecting frame, a rack, a gear and a spiral roller are used, after a stamping stub bar enters a falling groove, a part of burrs are possibly accumulated in the falling groove, at the moment, the second connecting frame is driven by the movable die to slide, and then the second connecting frame drives the spiral roller to rotate through the action of the rack andthe gear, the burrs are cut, rapid falling is achieved, and blocking is avoided.

Description

technical field [0001] The invention belongs to the technical field of stamping dies, in particular to a single punching die for punching holes and cutting edges of brake discs and brake wheels of automobiles. Background technique [0002] Stamping die is a special process equipment for processing materials (metal or non-metal) into parts (or semi-finished products) in cold stamping processing, called cold stamping die (commonly known as cold stamping die). Stamping - is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation to obtain the required parts. [0003] However, when the traditional stamping die is used, the workpiece is usually installed or taken directly under the stamping head, which has certain dangers. In addition, some burrs generated after stamping will easily accumulate and block the blanking groove. The present invention proposes a solution to the a...
