Punching machine for aluminum profile

Abstract

The invention discloses a punching machine for an aluminum profile. The punching machine comprises a machine table and a power device arranged on the machine table. The power device is connected witha punching rod, and a punch is arranged on the lower portion of the punching rod. A stamping die is arranged on the machine table and further located below the power device, and the stamping die comprises an upper die body and a lower die body. The upper die body is transversely and fixedly arranged on the machine table and is further provided with a rectangular through hole used for containing the aluminum profile, and the aluminum profile is in clearance fit with the inner wall of the rectangular through hole. A first positioning hole suitable for the punch to penetrate through is formed between the top of the upper die body and the inner wall of the top of the rectangular through hole. The lower die body is provided with a second positioning hole suitable for the punch to penetrate through, and a supporting frame is arranged at the bottom of the lower die body. The lower die body and the supporting frame are arranged in the aluminum profile in a sleeved mode. A guide rod fixedly connected with a U-shaped supporting frame is arranged at the rear end of the supporting frame and is further provided with a locking device. The punching machine solves the problems that when a traditional punching technology is used for punching the aluminum profile, the aluminum profile is prone to deformation, and the die is prone to damage.

Description

technical field [0001] The invention relates to the technical field of punching machines, in particular to a punching machine for aluminum profiles. Background technique [0002] With the development of new materials, aluminum profiles are widely used in various fields. When processing aluminum profiles, it is often encountered that holes are processed on aluminum profiles, commonly known as punching. The traditional process is punching through a CNC punching machine, but due to the low hardness of aluminum profiles, during the punching process, especially for Fangtong aluminum profiles, the aluminum profile is easily deformed by the impact of the punch. And can't adopt the traditional way to finish stamping. At the same time, the hydraulic pressure of the existing CNC punching machine with hydraulic transmission is relatively large, and the punching operation for a long time is easy to damage the mold, which increases the cost of purchasing and customizing the mold.
