[0026] Through the above technical scheme, the teeth 6 on the clamping plate 5 can keep the steel bar stable during clamping and positioning by the clamping plate 5 in cooperation with the rock wool pad 3.
[0027] Specifically, an electric push rod 7 is fixedly installed on the conveyer 2, and an extrusion disc 8 is fixedly connected to the output end of the electric push rod 7.
[0028] Through the above technical scheme, the output end of the electric push rod 7 penetrates through one side of the conveyer 2 and abuts against the clamping plate 5 through the extrusion disc 8, so as to indirectly stabilize and clamp the steel bar.
[0029] Specifically, the cutting protection mechanism includes a fixed table 9 fixedly installed on the device table 1, a table shaft 10 fixedly arranged inside the fixed table 9, a rotary arm 11 rotatably connected to the outer surface of the table shaft 10, an arc-shaped cover plate 12 provided at the top end of the rotary arm 11, wherein the arc-shaped cover plate 12 has two groups, and a handle 13 fixedly connected to the outer surface of the rotary arm 11.
[0030] Through the technical scheme, the two sets of arc-shaped cover plates 12 are arranged with gaps therebetween, and the gaps can accommodate the blade 21 to pass through, and the part of the rotating arm 11 close to the arc-shaped cover plate 12 is designed with a groove, so that the blade 21 can pass through better during the cutting adjustment of the blade 21.
[0031] Specifically, the top of the fixing table 9 is slidably connected with a connecting rod frame 14, the outer surface of the connecting rod frame 14 movably sleeved with a spring 15, and the top of the connecting rod frame 14 is fixedly provided with a bottom shaft 16.
[0032] Through the technical scheme, the connecting rod frame 14 is slidably connected with the fixing table 9 at the top of the fixing table 9, that is, the connecting rod frame 14 can be deeply inserted into the fixing table 9, and the spring 15 will be compressed and deformed during the process.
[0033] Specifically, the outer surface of the bottom shaft 16 is rotatably connected with a double pendulum piece 17, the inner side of the rotating arm 11 is fixedly provided with a top shaft 18, and the outer surface of the top shaft 18 is rotatably connected with the top of the double pendulum piece 17.
[0034] Through the technical scheme, under normal circumstances, the connecting rod frame 14 cooperates with the bottom shaft 16, the top shaft 18 and the double pendulum piece 17 to push the rotating arm 11 under the elastic resetting action of the spring 15, so that the arc-shaped cover plate 12 at the end of the rotating arm 11 is covered outside the cutting position of the steel bar.
[0035] Specifically, the driving mechanism includes a motor 22 fixedly installed on the displacement frame 19, the output end of the motor 22 is fixedly connected with a driving wheel 23, the outer surface of the driving wheel 23 is slidably connected with a conveying belt 24, one end of the rotating shaft 20 away from the blade 21 is fixedly connected with a transmission wheel 25, and the outer surface of the transmission wheel 25 is slidably connected with one end of the inner side of the conveying belt 24 away from the driving wheel 23.
[0036] Through the technical scheme, after the motor 22 drives the driving wheel 23 to rotate, the transmission wheel 25 can be driven to rotate synchronously by cooperating with the conveying belt 24 with just the right tightness, and finally the blade 21 is driven to rotate at high speed by the rotating shaft 20.
[0037] Working principle: in the process of cutting the steel bar, the steel bar is conveyed on the conveyor 2. Before the steel bar is conveyed to the position of the blade 21, the handle 13 needs to be pulled to move the swing arm 11. In this process, the swing arm 11 will rotate along the table shaft 10, and the swing arm 11 will drive the double swing plate 17 to deflect through the top shaft 18 and the bottom shaft 16. During this period, the connecting rod frame 14 will be gradually driven into the fixed table 9 and compress the spring 15, until the arc-shaped cover plate 12 is lifted to a certain height (which will not hinder the normal transportation of the steel bar). Then, after the steel bar is transported to the appropriate position, the squeeze plate 8 is pushed by the electric push rod 7, and the squeeze plate 8 is used to resist the clamping plate 5, so that the clamping plate 5 rotates along the plate shaft 4 and tightly clamps the steel bar at the position in contact with the rock wool pad 3 (during this process, the good flexibility and high temperature resistance of the rock wool pad 3 can ensure that the steel bar is stably clamped, and at the same time, avoid sparks generated during the cutting process to cause the rock wool pad 3 to ignite). After the steel bar is stably positioned, release the handle 13, and under the elastic reset action of the spring 15, the swing arm 11 will be pushed to swing along the table shaft 10, so that the arc-shaped cover plate 12 is covered outside the cutting part of the steel bar, which plays a shielding effect. Finally, the position of the displacement frame 19 is pulled by the hydraulic cylinder 26 cooperating with the hydraulic rod 27, so that the displacement frame 19 bottom slides in the inside of the device table 1 during the process, gradually changing the position of the blade 21, until it is adjusted to the position in contact with the steel bar. Finally, the motor 22 is started to drive the driving wheel 23 to rotate, and under the transmission action of the conveyor belt 24, the transmission wheel 25 can be linked to rotate synchronously, and finally the blade 21 is driven by the rotating shaft 20 to rotate at high speed. The steel bar is cut by the high-speed rotating blade 21. During the cutting process, a large amount of sparks and debris will be generated, most of which will splash along the cutting track of the blade 21, so as to be stably shielded by the two arc-shaped cover plates 12, which plays an effective protection effect, effectively avoiding the harm to the nearby electrical equipment or even the staff caused by the sparks and debris in the splashing process.
