Abstract

The invention relates to a forming device for a part with a hole. The forming device comprises a stamping die and a punching die, wherein the transverse size of a cavity of the stamping die is larger than that of the part, the punching die comprises an edge cutting device, and the edge cutting device is used for cutting off an enlarged area of a semi-finished product to form the part. According to the forming device, excessive complex structures do not need to be arranged in the cavity of the punching die, the part is formed through shaping and trimming of the edge cutting device consistent with the part in appearance, and therefore the precision requirement and cost of the dies are reduced under the condition that the forming precision of a formed product is not reduced. The invention further relates to a forming method of the part with the hole.

Description

technical field [0001] The present invention relates to a forming device for a part with a hole, and also relates to a forming method comprising the above-mentioned forming device. Background technique [0002] The stamping process is a forming process method that uses a press and a corresponding mold to apply an external force to a plate, bar, etc. to cause plastic deformation or separation, thereby obtaining a workpiece of the desired shape and size. [0003] The disadvantage is that in the stamping process, it is often accompanied by the generation of flash, which is a relatively common adverse phenomenon. Flash, also known as burrs, usually occurs at the mold clamping position, usually due to insufficient mold clamping force, or poor flatness at the mold clamping position of the concave and convex molds. At present, the flash generated by stamping parts generally needs to go through a secondary process to eliminate it, which increases the mold cost and time cost. [00...
