Description
Technical Field
The invention relates to the technical field of material blanking, in particular to a square tube deformation-preventing punching die.
Background
The thick-wall square tube is widely applied to industrial engineering, and a plurality of round holes or rectangular holes or strip holes are formed in the side wall of the square tube for convenient installation and weight reduction. In a traditional pipe punching die, particularly when a square pipe is punched, only a punching male die is used, no relevant supporting piece is arranged in a pipe core, and after punching is finished, severe technical defects such as corner collapse around a hole shape, male die clamping and bulging of the side wall of the square pipe occur. If the supporting piece is simply added, the bottom of the square tube can be extruded and deformed again when the square tube is punched.
Meanwhile, in the prior art, the square tube punching is generally carried out by adopting a common punching machine, so that the production efficiency is low, the labor intensity of workers is high, the production cost is high, the product quality is unstable, especially, the hole spacing is difficult to keep consistent, and the one-time punching of the long square tube cannot be directly finished.
Therefore, how to change the current situation that the square tube is easy to have defects in punching and the technical problem that the long square tube cannot be punched at one time in the prior art becomes a problem to be solved by the technical staff in the field.
