Abstract

The invention discloses an L-shaped plate punching die. The L-shaped plate punching die comprises a bottom die body, a top die body and a movable die plate. Guide pillars are vertically arranged on the bottom die body. The L-shaped plate punching die is characterized in that a limiting groove is formed in the bottom die body, an upper punching opening, a first expanding channel communicating withthe upper punching opening and a sliding block channel communicating with the first expanding channel are formed in the bottom die body, a punching block is arranged in the sliding block channel in asliding mode, an inclined face is formed on one side of the punching block, a side punching head is arranged on the other side of the punching block, an upper punching head is connected to the lower portion of the movable die plate, a pushing face is arranged at the end of the upper punching head, a power mechanism for pushing the movable die plate to move along the guide pillars is arranged on the movable die plate, an upper through hole for the upper punching head to penetrate through is formed in the top die body, connecting springs are arranged on the guide pillars in a sleeving mode, theupper ends of the connecting springs are connected with the movable die plate, and the lower ends of the connecting springs are connected with the top die body. The L-shaped plate punching die is usedfor synchronously punching the two side faces of an L-shaped thin plate, positioning and installing of the L-shaped plate can be facilitated, and the punching efficiency is high.

Description

technical field [0001] The invention relates to the stamping field, in particular to an L-shaped plate punching die. Background technique [0002] For the particularity of the shape of the L-shaped sheet, it is necessary to design a special included angle for clamping. Manual punching is used. Each punching can only punch one side. When the other side also needs to be punched, it needs to be punched. The L-shaped plate is repositioned and clamped, and the processing efficiency is low. At the same time, it is also prone to overturning during punching, which is likely to cause danger. [0003] For the particularity of L-shaped plate processing, the existing Chinese invention patent with publication number CN110355262A discloses "A Punching Device for L-shaped Steel Members for Electric Control Cabinets", which includes a processing table and multiple supporting feet installed at the lower end of the processing table. And the frame set on the upper end of the processing table,...
