Description

Technical Field

[0001] This application relates to the field of profile steel processing technology, and in particular to a feeding device for a profile steel cutting machine. Background Technology

[0002] Section steel is a type of bar steel with a specific cross-sectional shape and size. It is one of the four major types of steel. After the section steel is processed, it needs to be cut into the required length according to actual needs to facilitate subsequent transportation or use.

[0003] A search revealed an existing patent (publication number: CN118926734A) that discloses a laser cutting device for structural steel. The device includes a movable support assembly comprising an outer connecting arm and a dynamic support component. The dynamic support component includes a lower crossbeam, and an adjustment knob is provided on the side of the lower crossbeam. The movable support structure automatically follows the laser cutting head, and when the structural steel is not being cut or has been cut, a fixed support component and a locking frame component provide support and avoidance. This solves the problems of complexity in manually adjusting the pad and laser damage to the support structure in the prior art, thereby improving cutting accuracy and processing efficiency. During the development of this application, the inventors discovered the following problems with the prior art:

[0004] The existing steel profiles do not have an automatic feeding and pushing structure. During processing, the steel profiles need to be placed on a rack and manually pushed by workers into the band saw cutting machine for cutting. However, due to the large weight of the steel profiles and the limited size of the workers' hands, the number that can be pushed each time is small, resulting in low cutting efficiency. Furthermore, manual pushing cannot guarantee that the cut lengths are the same.

[0005] Therefore, a feeding device for a steel cutting machine is proposed to address the aforementioned technical issues. Summary of the Invention

[0006] To address the aforementioned issues, this application provides a feeding device for a steel profile cutting machine.

[0007] This application provides a feeding device for a steel section cutting machine, which adopts the following technical solution:

The clamping and pushing component includes a connecting drive housing, a clamping connecting plate, and a connecting slide plate.

[0010] Preferably, the moving feeding assembly is U-shaped, a lifting cylinder is inserted into the center of the moving feeding assembly, and the connecting driving machine box is connected to the bottom end of the telescopic shaft of the lifting cylinder.

[0011] Preferably, the connecting sliding plate is slidingly connected to the bottom of the clamping connecting plate, four groups of two-by-two symmetrical steel clamping blocks are slidingly connected to the bottom of the connecting sliding plate, and the bottom inner side of the steel clamping block is connected to the clamping bottom plate.

[0016] Preferably, the two ends of the reciprocating transmission sliding block are both connected to a limiting sliding block slidingly connected with the opening and closing sliding rail, and the steel clamping block is connected to the bottom of the limiting sliding block. The opening and closing rotating plate is shuttle-shaped.

[0017] Preferably, the transmission sliding rod is connected between the opening and closing rotating plate and the two groups of reciprocating transmission sliding blocks through an axis, the top of the fixed pressing block is connected to a lifting threaded rod through a bearing, and the lifting threaded rod is inserted into the center connecting cylinder through a thread.

[0018] By adopting the above technical scheme, the steel can be better fixed through the connected clamping structure, and the pushing and resetting actions can be completed in the process of loosening and releasing. The opening and closing driving gear is driven by the opening and closing motor to rotate, and the opening and closing transmission gear and the center connecting cylinder connected thereto rotate in the process of rotation. The center connecting cylinder drives the steel clamping block connected thereto to clamp or loosen in the process of rotation, and the lifting threaded rod in the center connecting cylinder is lifted in the process of rotation.

[0022] 2.

When the two groups of reciprocating transmission sliding blocks approach each other, the fixed pressing blocks move downward, and when the two groups of reciprocating transmission sliding blocks move away from each other, the fixed pressing blocks reset upward. When the clamping and pushing assembly is clamped, the reciprocating extension motor is in a state of being stationary or moving forward, and when the clamping and pushing assembly is released, the reciprocating extension motor is in a state of being stationary or moving backward. That is, when the profile steels are fixed, the profile steels can be pushed forward, and after the profile steels are pushed forward, the profile steels are released, and the reciprocating extension motor drives the clamping and pushing assembly to reset, so as to facilitate the next movement action.
