Abstract

The invention discloses a multifunctional combined punching die. In the invention, the head of a reversed T-shaped bottom plate is installed and fixed in a groove at the bottom of a lower template; a male die guide sleeve is movably fixed in an upper template; a male die fixing sleeve is sheathed in the male die guide sleeve; a compression spring is sheathed on the part of the male die fixing sleeve between the upper end of the male die fixing sleeve and the upper surface of the male die guide sleeve; a male die pressing block, a male die pressure bar and a punch head are sequentially arranged in the male die fixing sleeve from the top down, and the upper port of the male die fixing sleeve is sealed with a screw block; an elastic stripper plate with a punch hole is sheathed outside the lower end of the male die fixing sleeve; a female die locating sleeve is movably fixed on the lower template; and a female die is arranged in the female die locating sleeve, corresponding to the male die punch head. The multifunctional combined punching die is suitable for the hole machining of upright columns and mounting bars of a cabinet, and has the characteristics of high machining efficiency, less die cost and wide application range.

Description

technical field [0001] The invention belongs to the technical field of machining dies for cold stamping, and in particular relates to a multifunctional combined punching die. Background technique [0002] In the field of mechanical processing, especially in the field of cabinet body processing of complete sets of power transmission and distribution cabinets, the existing cabinet columns and holes of various shapes on the mounting strips are punched after programming by a CNC punching machine or through ordinary mechanical presses. It is stamped according to the upper mold, but the number of holes on these columns and the mounting strip parts are large, the shapes are different, and the hole distances are different. If the single hole is processed according to the above method, the productivity will be low; if the overall processing is performed, the number of molds will be too many and the cost will be high. Contents of the invention [0003] The purpose of the present in...
