Description

Technical Field

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

[0002] C-shaped steels are all automatically processed and formed by a C-shaped steel forming machine. The C-shaped steel forming machine can automatically complete the forming process of C-shaped steels according to the given C-shaped steel dimensions. C-shaped steels are widely used for purlins and wall beams of steel structure buildings, and can also be self-assembled into lightweight roof trusses, brackets and other building components.

[0003] For the existing C-shaped steel hydraulic punching device, such as a punching device for C-shaped steel processing disclosed in the utility model patent with the application number 202321101974.X, its main structure includes a feeding seat, a motor is fixedly connected to the right side of the feeding seat, the output shaft of the motor is fixedly connected to a threaded rod, a threaded block is threadedly connected to the outside of the threaded rod, a moving block is fixedly connected to the top of the threaded block, an adjusting plate is fixedly connected to the top of the moving block, driving blocks are fixedly connected to the left and right sides of the top of the adjusting plate, and a C-shaped steel body is movably connected to the top of the driving block; when in use, the C-shaped steel body to be punched is placed above the two driving blocks, and two driving motors can respectively drive two movable screw rods to rotate. Since the movable screw rods are threadedly connected to movable screw blocks, during the rotation of the two movable screw rods, the two movable screw blocks, the two limiting blocks and the two movable clamping plates will be respectively driven to move downward. During the downward movement of the two movable clamping plates, the C-shaped steel body can be clamped and fixed in cooperation with the two driving blocks, avoiding the phenomenon of falling off or offset of the C-shaped steel body during punching and adjustment, ensuring the punching effect of the C-shaped steel body. The hydraulic pump can pump hydraulic oil into the inside of the hydraulic rod, so that the hydraulic rod can be driven. The hydraulic rod can successively drive the movable push plate and the punching machine to move downward. During the downward movement of the punching machine, the C-shaped steel body can be punched.
