Positioning and punching device for metal plate machining

Abstract

The invention discloses a positioning and punching device for metal plate machining, and relates to the technical field of metal plate machining. The device comprises an operation table, a moving frame and a punching mechanism; the whole operation table is in an L shape; two L-shaped supporting frames are symmetrically arranged on the two sides of the front end of the operation table, and the two ends of each L-shaped supporting frame are fixedly connected to the two perpendicular side faces of the operation table correspondingly; a moving frame is arranged on the top faces of the L-shaped supporting frames in a sliding fit mode; a punching mechanism is arranged on the moving frame in a movable fit mode; and the punching mechanism comprises a rotating disc, a fixed disc and a first hydraulic cylinder, and one end of the first hydraulic cylinder is fixedly connected to the top of the side face of the fixed disc. Through arrangement of a rectangular clamping block, a middle-shaped positioning groove, a positioning block, a first motor, an air cylinder, a cylindrical sleeve, a top plate and an electromagnetic strip and cooperation of components, a punching head can be automatically and rapidly replaced when the device is used, the stability of the replaced punching head is high, and the punching quality of a metal plate can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of metal plate processing, in particular to a positioning punching device for metal plate processing, which is mainly used for the punching function of metal plate processing. Background technique [0002] In the processing and production of metal plates, stamping operations are often used to punch metal plates. Stamping is to apply external force to plates, strips, pipes and profiles by presses and molds to cause plastic deformation or separation. In order to obtain the forming and processing method of the workpiece (stamping part) of the required shape and size, the stamping device at the present stage is complex and diverse, with complete functions and a high degree of automation, which provides convenience for the punching of the plate. However, the existing stamping device is in The following drawbacks still exist in the use process: [0003] 1. When the existing stamping device stamps the plate, holes...
