Nested trimming die

Abstract

The invention discloses a nested trimming die. The nested trimming die comprises an upper die base and a lower die base, wherein an upper trimming knife block and at least one downwardly bulged punch are arranged on the upper die base; a lower trimming knife block is arranged on the lower die base, a garbage area is formed at the position, around the lower trimming knife block, on the lower die base, and die cases are fixedly arranged in the garbage area; and during die assembly of the upper die base and the lower die base, the upper trimming knife block and the lower trimming knife block work together to process a sheet into a main workpiece, and the punches and the die cases work together to process garbage formed by the main workpiece into other parts. Besides the upper trimming knife block and the lower trimming knife block which are conventionally arranged, the die cases are further arranged in the garbage area, and the corresponding punches are arranged on the upper die base, so that when the sheet is processed into the main workpiece, the formed garbage is processed into other parts in the garbage area, and accordingly, the purpose of saving raw materials is achieved. Compared with the prior art, the nested trimming die has the advantages that the generated garbage is processed into other parts as much as possible, so that the material utilization ratio is improved, and the material cost is lowered.

Description

technical field [0001] The invention relates to the technical field of dies, in particular to a sleeve type punching die. Background technique [0002] In the process of automobile manufacturing, molds are needed for the processing of many parts. Generally, after the mold is processed, waste will be generated. At present, the method of waste disposal is to directly slide the waste along the waste slide into the ground. In the pit, the waste materials are not treated in any way, which reduces the utilization rate of materials and increases the cost of materials. Contents of the invention [0003] The purpose of the present invention is to provide a sleeve-type punching die to solve the above problems. While processing the main workpiece, the generated waste is processed into other parts, so as to increase the utilization rate of materials and reduce the cost of materials. [0004] The invention provides a sleeve type punching die, comprising: [0005] The upper die base i...
