Embodiment 1

[0041] Set the square sleeve 2 on the workbench of the press, the hydraulic cylinder on the right side of the press drives the push rod 10 to push the square tube 16 to be punched into the square sleeve 2, and the skeleton connecting plate 13 on the left side of the press pushes the skeleton assembly 3 along the The inner wall of the square tube 16 to be punched moves to the right, and is placed in a position corresponding to the punching punch 1, and the punching punch 1 moves downward under the drive of the movable crossbeam of the press, as figure 2 As shown, the punching punch 1 descends to punch the square tube 16 to be punched, as image 3 shown. For a square tube with an outer wall length of 100mm and a wall thickness of 5mm, when performing high-precision punching with an aperture size of φ50mm, the diameter of the passing hole is 55mm, and the distance between the two horizontal support plates 5 is adjusted to 52mm. The distance between the plates 6 is 52 mm, and th...

Embodiment 2

[0043] For a square tube with an outer wall length of 100mm and a wall thickness of 5mm, when punching a rectangular hole of 50mm×40mm, the size of the passing hole is 55mm×45mm, and the distance between the two horizontal support plates 5 is adjusted to 55mm. The spacing between the longitudinal support plates 6 is 44mm, and the punching is completed under the drive of the press to obtain the required square tube side wall without deformation, and the rectangular hole meets the punching accuracy.

Abstract

The invention discloses a square pipe anti-deformation punching device, which comprises a punching punch, a square sleeve, a skeleton component, and a skeleton base. The skeleton bases are all arranged in square sleeves, and the skeleton components are arranged on the top of the skeleton base. The skeleton components include a transverse support plate, a longitudinal support plate and a longitudinal base. It is slidably arranged on the skeleton base, the longitudinal base is arranged between two transverse support plates, and the two longitudinal support plates are slidably arranged on the longitudinal base. Place the square ferrule on the outside of the square tube to be punched, the skeleton component is located inside the square tube to be punched, the horizontal support plate and the longitudinal support plate in the skeleton component form a quadrangular prism, which can support the upper side wall of the square tube to be punched, punch The hole punch moves down with the press to complete the square tube punching, effectively avoiding defects in the square tube.

Description

technical field [0001] The invention relates to the technical field of material blanking processing, in particular to a square tube anti-deformation punching device. Background technique [0002] Thick-walled square tubes are widely used in industrial engineering. In order to facilitate installation and reduce weight, multiple round or rectangular holes are opened on the side wall of the square tube. In traditional pipe punching dies, especially when punching square pipes, there is only a punching punch, and there is no punching die in the tube core. Serious technical defects such as bulging of the side wall. [0003] Therefore, how to change the current situation that square tube punching is prone to defects in the prior art has become an urgent problem to be solved by those skilled in the art. Contents of the invention [0004] The object of the present invention is to provide a square tube anti-deformation punching device to solve the above-mentioned problems in the p...
