[0023] Compared with the prior art, the invention has the following beneficial effects: the invention has a scientific and reasonable structure and is safe and convenient to use;

[0024] 1. A stress balancing mechanism is provided. Through the coordination of the mounting block, the slide bar, the square sleeve, the clamping plate, the vertical screw rod, the elastic plate, the spring, the switch and the side knife, a cutter wear degree inspection structure can be constructed. With the transmission conversion function of the driving screw rod, the transverse seat, the small turbine and the guide cavity, the cutter wear degree can be double-detected in a single shearing process, which effectively improves the controllability of the cutter wear degree, can timely and effectively grasp the cutter wear state, fully guarantee the stability and effectiveness of the shearing work, and improve the shearing efficiency and shearing quality simultaneously;

[0025] With the limiting function of the limiting plate, horizontal screw rod and linkage plate, the integrity of the cutter shape can be synchronously detected during the shearing process, and the curling and bending of the cutter can be discovered in time and effectively, avoiding further damage to the cutter due to stress imbalance, fully ensuring the balance and stability of the shear stress during the cutting process, and greatly reducing the cutting loss rate of hot rolled plates. In addition, the inspection of the wear degree of the cutter can make the state detection of the cutter more comprehensive and efficient, and the cutter can be repaired and replaced more timely and efficiently, improving the convenience and flexibility of the cutter maintenance work, and ensuring the shearing quality while giving full play to the performance of the cutter.

[0026] 2. Through the coordination of the accommodating chamber, piston plate, driving rod, lifting lug, guide wheel, steering wheel and traction rope, a driving force synchronous transmission conversion structure can be constructed, which can convert and utilize the useless driving force released by the hydraulic cylinder during the shearing process. On the one hand, it can greatly improve the effective utilization rate of the driving force, realize energy conservation and emission reduction in disguise, reduce equipment energy consumption, and improve economic benefits. On the other hand, it can effectively improve the compatibility, adaptability and timeliness of the shearing work and the cutter state detection, so that the cutter state detection work can be carried out more smoothly and efficiently, and the shearing quality and efficiency of the cutter can be improved in disguise.

[0027] Through the coordination of the air outlet valve, the air inlet valve, the duct and the connecting pipe, a complete air flow guide passage can be constructed. While ensuring the stability and smoothness of the cutter detection work, the air guide seat can be used to guide the cutter before and after shearing, and the clamping effect of the splint and the spring can be used to clean the debris on the surface of the cutter. The cutter can be in a relatively optimal state during the cutting work, and the wear rate of the cutter can be effectively reduced, thereby increasing the effective service life of the cutter.

[0028] 3. An intermittent material control mechanism is provided. Through the cooperation of the transmission box, turbine box, large turbine, reel, reel and ruler, a hot coil conveying control structure can be constructed. In addition, the limiting effect of the limiting ears and bolts can adjust and limit the single conveying length of the hot coil to achieve intermittent feeding, greatly improving the stability and reliability of the hot coil conveying work, making the conveying work and shearing work of the hot coil more compatible and adaptable. With the transmission effect and current limiting conversion effect of guide grooves, guide rods, shaft rods, hanging ears, discharge boxes, through holes, blocks, pull rods and ropes, the control accuracy of the single conveying length can be effectively improved, the convenience and effectiveness of the control of the conveying length can be improved, the shearing length can be more in line with the standard, the shearing quality of the hot coil can be improved, and the control cost of the hot coil conveying length control work can be reduced, and the economic benefits can be further improved.

[0029] 4. Through the cooperation of the piston chamber, the drive plate and the connecting rod, the useless work released by the hydraulic cylinder can be further transmitted and converted, providing a stable power source for the hot coil conveying work. While further improving the energy utilization rate of the equipment and reducing the cost of hot coil processing, the connection stability and synchronization between the hot coil conveying work and the shearing work are greatly improved, making the operation of each link of the equipment smoother and more stable, and indirectly improving the shearing efficiency of the hot coil, and effectively avoiding the damage of the equipment and the hot coil caused by the conflict between the hot coil conveying work and the shearing work, and indirectly improving the safety and stability of the shearing work;

[0030] By cooperating with the inflation valve, exhaust valve, three-way pipe and exhaust nozzle, a complete airflow drive passage can be constructed, which can greatly improve the driving force stability during the hot coil conveying process. Combined with the limiting effect of the driving roller and roller sleeve and the dual adsorption effect of the strip box, support plate, branch pipe, negative pressure box, bent hole, rubber ring and soft magnet, the effectiveness of the conveying work can be fully guaranteed, the control accuracy and convenience of the one-way conveying length of the hot coil can be improved, and the conveying work can be more efficient and reliable.

[0031] In summary, the hot coil shearing equipment can synchronously cool down and inspect the state of the cutter during the shearing process of the hot coil, and can timely and effectively feedback the wear and appearance of the cutter, fully ensure the effectiveness and reliability of the cutting work, give full play to the performance of the cutter, improve the shearing efficiency, and can synchronously intermittently convey the hot coil, accurately control the single conveying length, so that the shearing work and the hot coil conveying work are more compatible and adaptable.

[0063] Working principle and use process of the present invention: In actual use of the hot coil plate shearing equipment, firstly, the lathe 100 is moved to the working area, the external unwinding mechanism is aligned with the conveyor belt 104, the external material receiving mechanism is placed at the bottom of the conveyor belt 104 away from the side of the pressure roller 112, and the hot coil is pulled from the external unwinding mechanism, so that the hot coil passes through the gap between the support roller 108 and the pressure roller 112. Under the limiting and guiding action of the limiting rod 109, the compression spring 110 will give the roller seat 111 a vertical downward elastic extrusion force, and the dead weight of the pressure roller 112 will force the pressure roller 112 and the support roller 108 to press the hot coil. During the conveying process of the hot coil, the hot coil is flattened to provide good cutting conditions for the cutting work;

[0064] Then, a proper amount of air is filled into the discharge box 322 through the valve 3221 to give elastic support to the block 324. Here, the air pressure on the bottom of the block 324 should be greater than the initial resistance encountered by the reel 315 during rotation, so that the block 324 is tightly attached to the through hole 323 under the action of air pressure to block the through hole 323. Then, the bolt 318 is rotated and removed, so that the reel 316 can rotate freely relative to the large turbine 313 inside the transmission box 303. Then, one reel 316 is rotated to adjust the size of the reel 315. The tape 319 is wound and unwound, and according to the scale 3191 on the tape 319, the length of the tape 319 wound on the outside of the corresponding reel 315 is the shear length of the hot coil, and then the reel 315 on the other side is rotated to wind up the other tape 319, so that the length of the tape 319 wound on the outside of the reel 316 on the other side is zero, and then the bolt 318 is installed and reset, so that the reel 316 cannot rotate freely relative to the large turbine 313 inside the transmission box 303, and the single feeding length of the hot steel coil is limited;

[0065] Then, air is injected into the flow limiting box 2271 through the air nozzle 2274 to give elastic support to the valve block 2272, so that the air pressure received by the valve block 2272 is greater than the resistance received by the small turbine 215 during the rotation process, so as to take into account the cooling and detection work of the cutter 103. Then, the horizontal screw rod 208 or the top rotating part of the linkage plate 209 is rotated to drive the linkage plate 209 to move, and the distance between the linkage plate 209 and the switch 213 at the end of the mounting block 203 is adjusted. The distance is the maximum bending and curling width allowed by the cutter 103. Then, the vertical screw rod 210 is rotated to drive the elastic plate 211 to move, and the distance between the elastic plate 211 and the switch 213 at the bottom of the transverse displacement seat 202 is adjusted. The distance is the maximum wear amount allowed by the cutter 103, so as to synchronously detect the state of the cutter 103 during the hot coil shearing process.

[0066] Here, one side of the pressure roller 112 is defined as the rear side and the other side as the front side. During the hot coil shearing process, as the hydraulic cylinder 101 drives the mounting seat 102 to press down, the lifting ear 220 will drag the traction rope 223. Under the limit guidance of the guide wheel 221 and the steering wheel 222, the traction rope 223 will drag the driving rod 219, forcing the driving rod 219 to drive the piston plate 218 to move forward, and then the piston plate 218 will press the air on its front side through the corresponding front side outlet valve 224, and press it into the corresponding guide cavity 216 through the conduit 226. The corresponding small turbine 215 drives the driving screw 201 to rotate under the action of air pressure, driving the transverse displacement seat 202 to move, and then the air will be pressed into the air guide seat 227 through the connecting pipe 228, and discharged under the guidance of the air guide seat 227, blowing the cutter 103 to cool the cutter 103;

[0067] During the displacement of the transverse shift seat 202, the clamping plate 206 will be in close contact with the cutter 103 under the elastic pressure of the spring 212, scrape off the debris on the surface of the cutter 103, and detect the state of the cutter 103. As the shearing work proceeds, the cutter 103 will be worn accordingly. As the cutter 103 wears, its vertical section and the vertical section of the side knife 214 will have dimensional deviations. When the clamping plate 206 is in close contact with the cutter 103, the elastic plate 211 will rise relatively due to the dimensional deviation of the cutter 103 wear. When the wear deviation exceeds the allowable value, the elastic plate 211 will press the corresponding switch 213, and the switch 213 will control the hydraulic cylinder 101 to sleep, and send a warning signal to the external alarm, prompting the staff to replace the cutter 103 to maintain the stability of the cutting work.

[0068] Similarly, during the shearing process, if the cutter 103 bends or curls due to uneven stress during the cutting process and other unexpected factors, during the displacement of the transverse displacement seat 202, the pressure of the two clamping plates 206 from the cutter 103 will deviate, and then the squeezing force of the two clamping plates 206 on the spring 212 outside the square sleeve 205 will also deviate, causing the limit plates 207 on both sides to deviate to one side along the slide bar 204 under the action of the pressure difference, and causing the linkage plate 209 to move synchronously under the drive of the horizontal screw rod 208. When the bending or curling degree of the cutter 103 exceeds the allowable value, the switch 213 on one side of the mounting block 203 will be pressed by the linkage plate 209. At this time, the switch 213 will control the hydraulic cylinder 101 to sleep, and send a warning signal to the external alarm, prompting the staff to replace and repair the cutter 103;

[0069] When the lateral displacement seat 202 is completely displaced to the other side, it cannot be displaced any further. Accordingly, under the restriction of the driving screw 201, the small turbine 215 cannot rotate any further. At this time, as the mounting seat 102 is pressed downward, the air pressure on the front side of the piston plate 218 will rise. When the air pressure is sufficient to offset the pressure exerted by the air pressure inside the flow limiting box 2271 on the valve block 2272, the valve block 2272 will be displaced under the action of the air pressure on the front side of the piston plate 218, and the bypass pipe 2273 will no longer be blocked. The air on the front side of the piston plate 218 will be pressed into the bypass pipe 2273 through another air outlet valve 224 on the front side thereof, and then sent to the air guide seat 227, and discharged through the air guide seat 227 to blow the cutter 103 to continue cooling it.

[0070] After the cutter 103 completes the cutting action, as the hydraulic cylinder 101 drives the mounting seat 102 to rise, the lifting ear 220 will drag the traction rope 223. Under the limit guidance of the guide wheel 221 and the steering wheel 222, the traction rope 223 will drag the driving rod 219, forcing the driving rod 219 to drive the piston plate 218 to move backward, and then the piston plate 218 will press the air on its rear side through the corresponding rear air outlet valve 224, and press it into another guide cavity 216 through the conduit 226, forcing another small turbine 215 to drive the driving screw 201 to rotate in the opposite direction under the action of air pressure, driving the lateral displacement seat 202, and then the air will be pressed into the air guide seat 227 through the connecting pipe 228, and discharged under the guidance of the air guide seat 227, blowing the cutter 103 to cool the cutter 103;

[0071] Also, during the downward pressing process of the mounting seat 102, the driving rod 219 will drag the driving plate 305 to move forward through the connecting rod 306, and the driving plate 305 will press the air inside the piston chamber 304 into the transmission box 303 through the three-way pipe 320, forcing the large turbine 313 inside the transmission box 303 to rotate, and then discharge it through the exhaust nozzle 321, and the reel 316 and the driving roller 301 will rotate synchronously under the drive of the large turbine 313, and the driving roller 301 will drive the conveyor belt 104 to rotate through the roller sleeve 302 to convey the hot coil, and the reel 316 will reel the tape 319;

[0072] During the rotation of the conveyor belt 104, the hot coil presses against the negative pressure box 3024 under the action of gravity, forcing the negative pressure box 3024 to press the support plate 3022 downward through the branch pipe 3023, and then under the conduction of the curved hole 3025, the air inside the negative pressure box 3024 is extracted through the branch pipe 3023, and negative pressure is formed outside the rubber ring 3026. With the magnetic attraction of the soft magnet 3027, the hot coil is doubly adsorbed. As the conveyor belt 104 rotates, the hot coil is dragged, so that the hot coil is displaced with the rotation of the conveyor belt 104, thereby improving the transportation stability of the hot coil;

[0073] When the winding length reaches the cutting length, the tape 319 on a reel 315 will be completely released. At this time, as the reel 316 rotates, the reel 315 will drive the turbine box 312 to slide along the guide groove 309 under the drag of the tape 319. The turbine box 312 will pull the pull rod 325 through the rope 326, forcing the block 324 to overcome the air pressure and descend, thereby releasing the blockage of the through hole 323. At this time, the conveying length of the hot coil reaches the set value, and the driving plate 305 will press the air inside the piston chamber 304 into the discharge box 322 through the three-way pipe 320 and discharge it through the through hole 323, and no longer send it to the transmission box 303, and the conveyor belt 104 stops rotating;

[0074] During the downward pressing process of the mounting seat 102, the driving rod 219 will drag the driving plate 305 to move backward through the connecting rod 306, and the driving plate 305 will press the air inside the piston chamber 304 into the turbine box 312 through the three-way pipe 320, forcing the large turbine 313 inside the turbine box 312 to rotate, and then discharge it through the exhaust nozzle 321. The reel 315 will rotate synchronously driven by the large turbine 313 to rewind and reset the tape 319.

[0075] When the winding length reaches the cutting length, the tape 319 on a reel 316 will be completely released. At this time, as the reel 315 rotates, the reel 315 will drive the turbine box 312 to slide along the guide groove 309 under the drag of the tape 319. The turbine box 312 will pull the pull rod 325 through the rope 326, forcing the block 324 to overcome the air pressure and descend, thereby releasing the blockage of the through hole 323. The driving plate 305 will press the air inside the piston chamber 304 into the discharge box 322 through the three-way pipe 320 and discharge it through the through hole 323, completing the resetting of the tape 319. Under the limiting action of the deflection plate 3011 and the deflection guide groove 3012, the roller sleeve 302 will not rotate with the driving roller 301 during this process. This cycle is repeated to synchronously and intermittently convey the hot coil, and control the cutting length to achieve precise cutting.
