Positioning punching device for aluminum profile mold machining

The invention discloses a positioning punching device for aluminum profile mold machining. The positioning punching device comprises a workbench. Strip-shaped steps are correspondingly formed on the two sides of the workbench. A mold clamping mechanism is arranged between the two strip-shaped steps. Longitudinal guide rails arranged along the strip-shaped steps are correspondingly arranged on the two strip-shaped steps. A beam sliding along the longitudinal guide rails is arranged across the two longitudinal guide rails. A longitudinal drive mechanism is connected to the beam. A transverse guide rail is arranged on the beam. A support block sliding along the transverse guide rail is arranged on the transverse guide rail. A transverse drive mechanism is connected to the support block. A suspension arm support mechanism is arranged on the support block. A punching mechanism is arranged on the suspension arm support mechanism. According to the positioning punching device for aluminum profile mold machining, an a
