Double-side flanging compact type rotary stamping mechanism

Abstract

The invention discloses a double-side flanging compact type rotary stamping mechanism which comprises an upper die base and a lower die base. A flanging base is arranged on the front portion of the lower die base, two flanging inserts are arranged on the upper surface of the flanging base, and each flanging insert is composed of a bottom rotating part and a top flanging part; grooves allowing the rotating parts to be embedded and rotationally connected are formed in the upper surface of the flanging base in a bilateral symmetry manner, rotating shafts extend outwards from the front ends and the rear ends of the rotating parts, protruding columns extend outwards from the front ends and the rear ends of the flanging parts correspondingly, and the two protruding columns at the front ends of the two flanging parts and the two protruding columns at the rear ends of the two flanging parts are connected through tension springs correspondingly; and a driving block capable of moving up and down in the vertical direction is arranged on the upper die base, and the driving block can be inserted between the two flanging parts and exert pressure to the two flanging parts so that the two flanging inserts can rotate outwards around the rotating shafts. The double-side flanging compact type rotary stamping mechanism has the advantages that the structure is simple and compact, the die production cost is reduced, meanwhile, the problems of material blocking during flanging, space compactness caused by common dies of left and right parts and the like are solved, and automatic production can be effectively met.

Description

technical field [0001] The invention belongs to the field of stamping dies, and in particular relates to a double-side flanging compact rotary stamping mechanism. Background technique [0002] In the flanging process of stamping parts, for parts flanging, especially when flanging at a negative angle, when pressing parts, the plate is prone to springback, and there will also be a phenomenon of flanging and jamming. These problems will greatly reduce the quality of flanging, and will also increase the workload of on-site commissioning personnel. CN106694660A discloses a negative-angle flanging stamping mechanism for parts, which solves the above problems to a certain extent, but it has the following problems: it is necessary to design a lower die support block that can move up and down on the lower die base, and a sliding wedge that moves left and right. It is necessary to design an upper wedge and an upper mold forming block on the upper mold base. The upper inclined wedge i...

Problems solved by technology

[0002] In the flanging process of stamping parts, for parts where the flanging is performed, especially when the flanging is performed at a negative angle, the plate is prone to springback when pressing the part, and there will also be a phenomenon of flanging and jamming once. These problems will greatly reduce the quality of flanging, and will also increase the workload of on-site commissioning personnel

CN106694660A discloses a negative-angle flanging stamping mechanism for parts, which solves the above problems to a certain extent, but it has the following problems: it is necessary to design a lower die support block that can move up and down on the lower die base, and a sliding wedge that moves left and right. It is necessary to design the upper wedge and the upper mold forming block on the upper mold base. The upper inclined wedge is used to drive the sliding wedge movement, and the upper mold forming block can move left and right under the action of the upper driving block. The overall structure is complex and the mold processing cost is high.
