Description

Technical Field

[0001] The present application relates to the field of punching processing technology, and in particular to a punching device. Background Art

[0002] Punching, as an important pressure processing method, is widely used in industrial production. It is mainly used to produce specific concave and convex shapes on the surface of materials, forming through holes or slits. Punching can be applied to a wide range of materials, such as steel, leather, cloth, and wood. Punching materials include stainless steel, copper, iron, aluminum, mild steel, galvanized steel, PVC, cold-rolled coil, and hot-rolled sheet. Pipe punching processes are mainly divided into steel die punching and rubber die punching.

[0003] When punching, a punch press or other equipment is usually used. Through the action of the die, the metal material is subjected to strong pressure in an instant, causing plastic deformation, thereby forming a hole of the desired shape on the material. The shape and size of the punched hole are determined by the shape and size of the punch.

[0004] In the prior art, when using existing punching devices such as punch presses, the punching pressure is concentrated at the punching area, causing the material to warp upward during the punching process, affecting the accuracy and quality of the punching. Furthermore, the material and the existing punching devices are often in sliding contact, resulting in significant frictional resistance during movement, reducing production efficiency and increasing equipment energy consumption.

[0005] Therefore, it is necessary to provide a new technical solution to improve one or more problems existing in the above solutions. Utility Model Content

[0056] In one embodiment, a guide contact cylinder 340 is rotatably provided on the outer side of the guide bearing column 330 for rolling contact with the material to be punched 600, thereby reducing friction when the punching material 600 moves.

[0057] Optionally, the middle part of the guide bearing column 330 is an optical axis, and the top has a limiting boss. The guide contact cylinder 340 is limited by the limiting boss and the guide adjustment block 320, and is rotatably connected to the optical axis of the guide bearing column 330, thereby realizing the outer rotational connection between the guide contact cylinder 340 and the guide bearing column 330, wherein the limiting boss and the top of the guide adjustment block 320 form a groove to limit the guide contact cylinder 340 in the groove.

[0065] When the punching device provided in the embodiment of the present application is in use, the fixed plate 140 is fixed below the punch head, and the punching material 600 is placed on the fixed carrier plate 100. After adjusting the position of the punching material 600, the guide adjustment rod 310 is rotated using a dedicated tool, causing the two guide adjustment blocks 320 to move inward simultaneously, clamping the punching material 600 via the guide contact cylinder 340. The carrier lifting rod 220 is then rotated to move the lifting assembly 230 downward. The first contact roller 240 outside the lifting assembly 230 presses the punching material 600 to limit its position. It should be noted that the first contact roller 240 should not be too tight when pressing the punching material 600. After the punching operation, the punching material 600 is moved under the rolling contact of the first contact roller 240, the second contact roller 500, and the guide contact cylinder 340.
