[0035] As a preferred solution, the conveying rubber roller 45 can be located above the first cross arm 23 for the conveying rubber roller 45 to push up the steel to contact and apply force to the steel.

[0036] The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process, and the specific work is as follows.

[0037] The equipment is stably placed through the base 11 in the main body structure 1. After the equipment is powered on, the equipment can be adjusted according to flat steel with different widths for limiting and conveying, and the cutting structure can be carried out; When the width of the flat steel is small: The first hydraulic cylinder 31 in the second limiting structure 3 drives the lifting frame 32 to rise, so that the second limiting component 33 on the second lifting frame 32 corresponds to the first limiting component 24 arranged in series relatively through the cross arm. Then, the concave limiting seat 331 can be arranged relatively, and according to the width of the flat steel, the width-adjusting slide rail 21 in the first limiting structure 2 is driven to drive the first limiting components 24 on the two support frames 22 to move relatively, so as to adjust the distance between the first limiting component 24 and the second limiting component 33. Then, two working stations can be formed. The two flat steels are placed between the relatively arranged first limiting component 24 and the second limiting component 33, and are clamped and blocked by the concave limiting seat 331. The upper and lower side walls of the flat steel are in contact with and limited by the first guide rollers 332, and the two sides of the flat steel are in limiting contact with the second guide rollers 333. Furthermore, through the separate driving of the conveying components 4 on the two support frames 22, first drive the conveying component 4 on one support frame 22. Driven by the motor 46 on the machine base 44, drive a pulley 47 on the driving end to rotate, and drive the conveying rubber roller 45 to rotate by means of the transmission belt 48. At the same time, drive the second hydraulic cylinder 41 to drive the wheel seat 42 to rise, so that the conveying rubber roller 45 contacts the lower wall of the flat steel, and the flat steel is jacked up and clamped on the first guide roller 332 at the top of the limiting seat 331. When the conveying rubber roller 45 rotates, the flat steel is stressed and moves by means of the first guide roller 332 and the second guide roller 333, and one end of the flat steel is conveyed towards the cutting machine main body 14. At the same time, the rotation of the conveying rubber roller 45 keeps the wheel seat 42 stable through the assisting rod 43 to prevent the reverse force from damaging the second hydraulic cylinder 41. Furthermore, the cross-shaped slide rail 13 supported at a certain height by the hanger 12 in the main body structure 1 drives the cutting machine main body 14 to move back and forth to adjust the cutting length and cutting position. The cutting length is adjusted by driving the flat steel to move by the conveying rubber roller 45, and the cutting machine main body 14 is driven to move left and right by means of the cross-shaped slide rail 13 to cut one of the flat steels. After the cutting machine main body 14 cuts the flat steel on the left, that is, when the cutting wheel of the cutting machine main body 14 is at the flat steel working station on the left, the flat steel at the right working station is driven to move forward by the conveying rubber roller 45, so as to realize the alternating conveying and alternating cutting of the left and right working stations and improve the processing efficiency. When the width of the flat steel is large, single-station processing can be carried out: That is, the second limiting component 33 is lowered below the first limiting component 24 by retracting the first hydraulic cylinder 31. Then, according to the width of the flat steel or the plate, the width-adjusting slide rail 21 is used to drive the first limiting components 24 on the support frames 22 to adjust the distance, so that the plate can be inserted between the first limiting components 24 for limiting, and the plate is located above the second limiting component 33. At this time, the conveying components 4 on the support frames 22 are driven simultaneously to make the conveying rubber rollers 45 apply force to the lower walls at the left and right ends of the plate to drive the plate to move and convey, and cutting processing is carried out by means of the main body structure 1.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
