Description

Technical Field

[0001] The utility model relates to the technical field of punching devices, in particular to a C-shaped steel punching device. Background Art

[0002] C-shaped steel is a special-shaped steel made of cold-formed thin-walled steel, and its cross-sectional shape is "C". C-shaped steel has the characteristics of thin walls, light self-weight, excellent cross-sectional performance, and high strength. Compared with traditional channel steel, about 30% of materials can be saved under the same strength. It is widely used in the fields of construction, mechanical manufacturing, and bridge construction.

[0003] At present, during the processing of C-shaped steel, it is necessary to use punching equipment to punch holes in it.

[0004] The prior art publication number CN219093315U is an automatic punching device for C-shaped steel processing, including a workbench. One side of the top of the workbench is fixedly connected with an L-shaped plate. The top of the inner wall of the L-shaped plate is fixedly connected with two hydraulic rods. The bottom of the two hydraulic rods is fixedly connected with a movable plate. The bottom of the movable plate is fixedly connected with a punch. Both sides of the bottom of the movable plate are fixedly connected with springs. The bottom of the two springs is fixedly connected with T-shaped blocks. Through grooves are opened at both sides of the top of the workbench, and electromagnets are embedded on both sides of the top of the through grooves.

[0005] Although it can automatically feed materials through the combined action of the conveyor mechanism body, the limiting plate, the movable column and the ring body, and at the same time limit the C-shaped steel to ensure that the punching position of the C-shaped steel does not shift after feeding. However, in actual operation, it cannot limit the feeding stroke of the C-shaped steel, and it is difficult to ensure the moving stroke of the C-shaped steel. Therefore, when punching the C-shaped steel, the punching accuracy cannot be guaranteed. Moreover, during the movement of the C-shaped steel, the limiting plate is in contact with the outer wall of the C-shaped steel, resulting in a large frictional force between the two, which not only increases the moving resistance, but also easily damages the surface galvanized layer of some galvanized C-shaped steel.
