A metal stamping machine

Abstract

The invention belongs to the technical field of hardware stamping, and particularly relates to a hardware punching machine. The hardware punching machine comprises a plate clamping device and furthercomprises a frame body; the opposite sides of a pressing block and a fixing block are arranged in an inclined manner, and the spaces are decreased from left to right; the upper and lower surfaces of arotating block are arranged in an inclined manner with respect to the pressing block and the fixing block; a rotating shaft of a motor passes through the rotating block and is fixedly connected withthe rotating block; an object bearing block is arranged below the pressing block; the lower surface of the object bearing block is fixedly connected with a limiting block; the limiting block is vertically arranged and is in a T shape; and the inner wall of the bottom of the frame body is fixedly connected with two buffer seats. By means of the hardware punching machine, hardware can be fixed in all directions, so that the hardware is completely fixed; rubber bags are in direct contact with the upper and lower surfaces of the hardware in the fixing process, and therefore damage to the hardwarecan be avoided; meanwhile, the friction force between rubber rings and the hardware is large, and therefore sliding of the hardware is effectively prevented; and the rubber bags arranged in a staggered manner enable the hardware to be completely fixed, and stress is more even.

Description

technical field [0001] The invention belongs to the technical field of metal stamping, in particular to a metal stamping machine. Background technique [0002] Metal stamping is a common processing method for hardware at present. Stamping the hardware makes the hardware have different shapes and structures, which is convenient for further processing and assembly of the hardware in the later stage. [0003] Some clamping device technical solutions for metal stamping machines have also appeared in the prior art. For example, a Chinese patent with application number 2017103064174 discloses a metal stamping machine, including a device body; the device body is mainly composed of a base, It consists of a top plate, a partition plate, a fixed boss and a pressure plate; the base and the top plate are fixedly connected by a side plate, and a partition plate is arranged horizontally inside the device body, and a rotating shaft is vertically arranged inside the device body, and the rot...

Problems solved by technology

[0005] In order to make up for the deficiencies of the existing technology and solve the problem of incomplete fixing of hardware and damage to hardware during the fixing process, a metal stamping machine proposed by the present invention, the metal stamping machine, including a plate clamping device, contacts the hardware through a rubber bag It can prevent scratches during the fixing process of the hardware, and the friction between the rubber bag and the hardware is relatively large, which can effectively prevent the hardware from sliding after fixing, and the hardware can be subjected to upward and downward pressure through the extrusion block and the bearing block. Force fixing, the second pneumatic cylinder drives the fixing plate to fix the hardware by force in the left and right directions, and then cooperates with the rubber bag to completely fix the hardware
