Abstract

The invention discloses an aluminum profile punching device. The aluminum profile punching device comprises a rack. A hydraulic punch is mounted at the top of the rack. A base plate is fixedly connected to the rack and located below the hydraulic punch. A first cylinder is vertically mounted at the bottom of the rack. The top of the first cylinder is fixedly connected with a first motor, a first annular tool apron is fixed to an output shaft of the first motor, and a plurality of first tool bits are annularly arranged on the first annular tool apron and hinged to the first annular tool apron. A template is slidably connected to the top surface of the base plate, a template hole is formed in the template, and an annular blade is arranged on the edge of the template hole. An annular cavity is formed in the hydraulic punch, a second motor is mounted at the top of the annular cavity and connected with a second annular tool apron through a connecting rod, the connecting rod is located in the annular cavity, and a plurality of second tool bits are fixedly connected to the bottom of the second annular tool apron. By adoption of the aluminum profile punching device, defects of the prior art can be overcome, and the machining quality of aluminum profile punching is improved.

Description

technical field

[0001] The invention relates to the technical field of machining, in particular to an aluminum profile punching device and a punching method thereof. Background technique

[0002] With the development of new materials, aluminum profiles have been widely used in various fields. When processing aluminum profiles, it is often encountered that holes are processed on aluminum profiles. The traditional process is to punch holes with a CNC punching machine, but due to the low hardness of the aluminum profile, burrs will be generated on the edge of the hole during the punching process, and the edge of the hole will be slightly concave; if the hole is drilled through a CNC machine tool Processing, and then grinding the edge of the hole can avoid the problems of burrs and sinking, but the processing process is complicated, time-consuming and costly. Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide an alumi...
