[0024] A fixing bolt 210 is inserted into one side of the top of the limit block 207, and one end of the fixing bolt 210 contacts the bottom of the inner wall of the connecting groove 209. A second motor 3 is fixedly provided on one side of the processing table 1, and one end of the bidirectional screw rod 202 is fixedly connected to the output end of the second motor 3. The fixing bolt 210 is threadedly connected to the inner wall of the limit block 207, and the position of the limit block 207 is fixed by squeezing it on the bottom of the inner wall of the connecting groove 209;

[0025] Furthermore, a chute 4 is provided in the middle of the top of the processing table 1, and a discharge chute 5 is provided at one end of the processing table 1, and the inner wall of the discharge chute 5 is connected to the inner wall of the chute 4, and the chute 4 is designed to be inclined at a certain angle, and the cut steel bars falling into the chute 4 will automatically slide into the discharge chute 5 to wait for collection;

[0026] Furthermore, the cutting mechanism 6 includes a mounting bracket 601 fixed on the top of the processing table 1 and located above the inclined groove 4, a cutting machine body 602 is installed at the bottom of the mounting bracket 601, a hydraulic cylinder 603 is installed on the top of the mounting bracket 601, and one end of the cutting machine body 602 passes through the inner wall of the mounting bracket 601 and is interlaced and connected with the output end of the hydraulic cylinder 603, and the hydraulic cylinder 603 lifts and lowers the cutting machine body 602 to contact the steel bar for cutting.

[0027] A connecting frame 604 is fixedly provided on one side of the shell of the cutting machine body 602, and an arc-shaped clamp 605 is inserted at the bottom of the connecting frame 604. A spring 606 is sleeved on the outer wall of one end of the arc-shaped clamp 605, and one end of the spring 606 is fixedly connected to the bottom of the connecting frame 604. When the cutting machine body 602 is cutting, the connecting frame 604 continues to press down and compress the spring 606, so that the arc-shaped clamp 605 squeezes the steel bar with greater force, and the steel bar can be kept more stable during the cutting process. After cutting, the cutting machine body 602 rises, and the connecting frame 604 rises with the arc-shaped clamp 605 and leaves the surface of the steel bar. The steel bar can continue to be transmitted under the transmission mechanism 2 and wait for the next cutting.

[0028] Working principle: When using the steel bar cutting machine for the construction industry in this design, the steel bar is placed on the upper end of the processing table 1 and transferred and moved through the transmission mechanism 2. During the transfer, the second motor 3 is started to rotate the bidirectional screw rod 202 and the support frame 203 to move closer to each other, so that the transmission rollers 204 on both sides contact and squeeze the two sides of the steel bar. The two first motors 205 are started to drive one of the transmission rollers 204 at both ends to rotate in the opposite direction, so that the steel bar is uniformly transferred to the cutting area of ​​the processing table 1 under the drive of the transmission rollers 204 on both sides. The cutting length is divided equally according to the needs. When the limit block 207 is slid in the second slide groove 206 to make the steel bar contact the pressure sensor 208 on one side, the cutting point is just below the cutting machine body 602. The pressure sensor 208 is squeezed to stop the drive of the two first motors 205, so that the steel bar stops being transferred. At this time, the cutting The mechanism 6 can cut the steel bar, and the cut steel bar falls into the inclined groove 4, and the first motor 205 loses the squeezing of the pressure sensor 208 and continues to drive the transmission roller 204 to rotate and transmit the steel bar. In one cycle, the long steel bar can be continuously cut into equal parts, which reduces the workload of the staff and improves the cutting efficiency. In the cutting process, the hydraulic cylinder 603 pushes the cutting machine body 602 to descend, and the connecting frame 604 on its shell descends together with it. Before the blade on the cutting machine body 602 contacts the steel bar, the arc clamp 605 contacts the steel bar first and fixes it. When the cutting machine body 602 contacts and continues to press down for cutting, the connecting frame 604 descends and compresses the spring 606 so that it does not affect the normal cutting of the steel bar, and squeezes the steel bar tightly to keep it fixed, and does not need to be manually fixed by the staff, thereby improving the stability of the device during operation.
