Description

Technical Field

[0001] The present invention relates to the technical field of steel processing equipment, and more specifically, to a positioning and punching device for steel processing. Background Art

[0002] Steel is a material with a certain shape, size and performance made by pressure processing of steel ingots, steel billets or steel. Most steel processing is through pressure processing, which causes plastic deformation of the processed steel. Cutting and grinding operations often occur during steel processing, and positioning and punching are also important processes in steel processing. For most steels, traditional punching equipment can meet the working needs, but for some steels with high thermal sensitivity, water cutting is a more effective method.

[0003] Most of the currently commonly used positioning and punching devices for steel processing require workers to position the punching location. For batch-processed steel, the position can be limited by positioning blocks. However, when different positions need to be punched on multiple steels, workers need to adjust the positions of the steels one by one, resulting in low efficiency. In addition, when processing by water cutting, sufficient safety space needs to be reserved at the upper and lower ends of the steel processing. For steels with different thicknesses, workers also need to ensure that sufficient safety space is reserved each time the device operates, greatly increasing the workload of the workers. Summary of the Invention

[0004] The purpose of the present invention is to provide a positioning and punching device for steel processing to solve the problems raised in the above background art.

[0005] A positioning and punching device for steel processing includes a buffer box. The upper end of the buffer box is fixedly connected with a working box. One side of the working box is fixedly connected with a control box. The upper end of the control box is fixedly connected with a water cutting preparation box. The water cutting preparation box is fixedly connected with the working box. A positioning component is arranged inside the working box. There are two groups of the positioning components. A water cutting component is arranged at the upper end of the positioning component. The water cutting component is fixedly connected with the working box. The central axis of the water cutting component coincides with the central axis of the working box. A connecting pipe is fixedly connected between the water cutting component and the water cutting preparation box. A discharge port is fixedly connected to one side of the buffer box close to the control box.

[0006] The positioning component includes baffles fixedly connected to the working box. There are two baffles. A protective plate is fixedly connected to the outer side of the baffles. A first protective plate is fixedly connected between the baffles. A fixing plate is slidably connected above the first protective plate. A limiting plate is fixedly connected to the upper end of the fixing plate. A clamping component is arranged at the upper end of the fixing plate. A side pressing plate is fixedly connected to one side of the fixing plate close to the water cutting component. The upper end of the side pressing plate is higher than the upper end of the fixing plate. A soft pad is arranged on one side of the side pressing plate away from the clamping component. The soft pad can reduce the influence caused by clamping the narrow surface of the steel, and at the same time increase the friction force to improve the clamping effect.

[0007] Preferably, the working box includes a bottom plate fixedly connected to the buffer box. A side plate is fixedly connected to the upper end of the bottom plate. A first bidirectional threaded rod is rotatably connected between the side plate and the control box. There are two first bidirectional threaded rods. One end of each first bidirectional threaded rod away from the side plate is provided with a motor. The motor is located inside the control box. A processing area is arranged at the center of the side plate. The processing area is a safe area for the device to process. A limiting block is fixedly connected to the upper end of the bottom plate. The limiting block is located on the central axis of the bottom plate. The limiting block can limit the movement of the sliding plate to prevent the sliding plate from moving excessively and causing collision.

[0008] Preferably, a sliding plate is threadedly connected to the outer side of the first bidirectional threaded rod. There are two groups of sliding plates. The sliding plates are symmetrically distributed with the limiting block as the axis of symmetry. A positioning component is fixedly connected to the upper end of each sliding plate. A first sliding rod is fixedly connected between the side plate and the control box. The first sliding rod is fixedly connected to the limiting block. A top plate is fixedly connected to the upper end of the side plate. The top plate is fixedly connected to the water cutting component.

[0009] Preferably, the water cutting assembly includes an electric telescopic rod fixedly connected to the working box. An infrared emitter is arranged outside the electric telescopic rod. The infrared emitter can project infrared rays downward, enabling the staff to intuitively see the processing area of the steel and the safe working range according to the projection of the infrared rays on the steel, making the processing of the steel safer and more accurate. The infrared emitter is fixedly connected to the working box. One end of the electric telescopic rod away from the working box is fixedly connected with a connecting column. One end of the connecting column away from the electric telescopic rod is fixedly connected with a water cutting head. A protective cover is arranged outside the water cutting head. The distance between the end of the protective cover and the end of the water cutting head is the safe distance required during the processing of the water cutting head. By the contact between the protective cover and the steel, the continuous movement of the electric telescopic rod is restricted, and thus the water cutting head and the steel are always in a safe processing position, enabling the device to be applicable to steel of different thicknesses. The protective cover is fixedly connected to the connecting column.

[0010] Preferably, a worm is rotatably connected between the two baffles. There are two worms. One end of the baffle away from the worm is provided with a motor I. The output end of the motor I is fixedly connected to one of the worms respectively. A turbine is meshed between the worms. The upper end of the turbine is fixedly connected with a rotating shaft. One side of the rotating shaft away from the turbine is rotatably connected with a sliding block. The two sides of the sliding block are slidably connected to the first protective plate. Through the meshing between the worm and the turbine, the rotation of the worm can control the rotation of the turbine. Furthermore, by controlling the rotation direction and speed of the two worms, the movement, rotation and speed of the turbine can be controlled, enabling the sliding block to move in a larger range, and thus enabling the steel to be moved more conveniently and reducing the number of adjustments to the steel.

[0011] Preferably, a limiting rod is fixedly connected between the two baffles, and the sliding block is slidably connected to the limiting rod. The limiting rod can limit the moving direction of the sliding block, making the movement of the sliding block more stable, thus achieving precise movement, enhancing the accuracy of device processing. The upper end of the sliding block is fixedly connected with a connecting plate, the rotating shaft passes through the connecting plate, and a gear is fixedly connected to the end of the rotating shaft away from the turbine. The gear is slidably connected to the connecting plate. A first fixing block is fixedly connected to the upper end of the connecting plate. A sliding rod is slidably connected to the first fixing block. A rack is arranged on the side of the sliding rod close to the gear, and the sliding rod meshes with the gear. A fixing block is arranged on the side of the gear away from the first fixing block, and the fixing block is fixedly connected to the connecting plate. A first limiting rod is slidably connected to the fixing block. Both ends of the first limiting rod and the sliding rod are fixedly connected to the fixing plate. Through the meshing of the sliding rod and the gear, the movement of the fixing plate is related to the rotation of the gear. Furthermore, the rotation direction of the worm can control the movement of the fixing plate, making the movement of the steel by the device more convenient.

[0012] Preferably, the clamping assembly includes a connecting block fixedly connected to the fixing plate. A sliding groove is arranged inside the connecting block. Two threaded rods are rotatably connected at the sliding groove. A first sliding block is threadedly connected to the outer side of the threaded rod. One end of the first sliding block away from the fixing plate is fixedly connected with a first fixing plate. The first fixing plate is slidably connected to the connecting block. A transverse clamping plate is fixedly connected to the upper end of the first fixing plate. A first trigger block is arranged at one end of the transverse clamping plate close to the side pressing plate. Two bidirectional threaded rods are rotatably connected inside the transverse clamping plate. A longitudinal clamping plate is threadedly connected to the outer side of the bidirectional threaded rod. The longitudinal clamping plate is slidably connected to the first fixing plate. A second trigger block is arranged at the opposite ends of the longitudinal clamping plate. By rotating the threaded rod, the first sliding block can be driven to move, and then the transverse clamping plate can be driven to move through the first sliding block to clamp both ends of the steel. At the same time, by rotating the bidirectional threaded rod, the longitudinal clamping plate is driven to move to clamp both sides of the steel, fixing the steel.

[0013] Preferably, a threaded rod is rotatably connected inside the longitudinal clamping plate. An upper clamping plate is threadedly connected to the outer side of the threaded rod. The upper clamping plate is slidably connected to the transverse clamping plate. A third trigger block is arranged at the lower end of the upper clamping plate. By rotating the threaded rod, the upper clamping plate can move, and then the transverse clamping plate can move synchronously to clamp the upper end of the steel, preventing the steel from shifting during processing and affecting the processing accuracy.

[0014] Compared with the prior art, the advantages of the present invention are as follows:

[0015] 1. In the present invention, by setting a positioning component and controlling the rotation direction and speed of the worm by a motor, the movement of the fixed plate can be controlled in linkage, so that the steel can move synchronously on the fixed plate, making the movement of the steel more convenient. At the same time, the steel is clamped by the clamping component so that the center point of the steel coincides with the center point of the device when the steel is fixed, so that the coordinates can be established with the center point of the device as the origin and the length and width of the steel as the coordinate axis, so that the position of the punching point on the steel is more accurate, and the steel can be controlled to be accurately moved to the processing position.

[0016] 2. In the present invention, by setting up a water cutting assembly, the infrared rays emitted by the infrared transmitter can make the processing area and the safe processing range of the device displayed on the steel. When drilling can be performed at any position, it is only necessary to ensure that the processing position is within the safe processing range, thereby increasing the safety of the device. At the same time, the contact between the protective cover and the steel can limit the extension and retraction of the electric telescopic rod, so that the water cutting head is at a safe distance from the steel each time processing.

[0017] 3. In the present invention, by setting a working box, when the staff places the steel on the positioning assembly and finds that the processing position of the steel coincides with the positioning assembly, the staff can control the reverse rotation of the bidirectional threaded rod 1 to make the two positioning assemblies move in opposite directions, and at the same time control the threaded rods to rotate synchronously so that the lateral clamping plates continue to move to clamp the steel, thereby achieving the goal of keeping the position of the steel stationary and reducing the overlapping portion between the positioning assembly and the steel, so that the staff can place the steel at any angle, thereby improving efficiency.

[0030] Example 1:

[0031] Please refer to Figure 1 , a positioning and punching device for steel processing, including a buffer box 1, a working box 6 is fixedly connected to the upper end of the buffer box 1, a control box 2 is fixedly connected to one side of the working box 6, a water cutting preparation box 3 is fixedly connected to the upper end of the control box 2, the water cutting preparation box 3 is fixedly connected to the working box 6, a positioning assembly 5 is arranged inside the working box 6, there are two groups of the positioning assemblies 5, a water cutting assembly 7 is arranged above the positioning assemblies 5, the water cutting assembly 7 is fixedly connected to the working box 6, the central axis of the water cutting assembly 7 coincides with the central axis of the working box 6, a connecting pipe 8 is fixedly connected between the water cutting assembly 7 and the water cutting preparation box 3, and a discharge port 4 is fixedly connected to one side of the buffer box 1 close to the control box 2;

[0032] Please refer to Figure 2 and Figure 3, the positioning assembly 5 includes baffles 502 fixedly connected to the working box 6. There are two baffles 502. A protective plate 518 is fixedly connected to the outer side of the baffle 502. A first protective plate 519 is fixedly connected between the baffles 502. A fixing plate 510 is slidably connected above the first protective plate 519. A limiting plate 512 is fixedly connected to the upper end of the fixing plate 510. A clamping assembly 513 is arranged at the upper end of the fixing plate 510. A side pressing plate 511 is fixedly connected to the side of the fixing plate 510 close to the water cutting assembly 7. The upper end of the side pressing plate 511 is higher than the upper end of the fixing plate 510. A soft pad is arranged on the side of the side pressing plate 511 away from the clamping assembly 513. The soft pad can reduce the influence caused by clamping the narrow surface of the steel, and at the same time increase the friction force to improve the clamping effect.

[0033] Please refer to Figure 10 and Figure 2 , the working box 6 includes a bottom plate 601 fixedly connected to the buffer box 1. A side plate 606 is fixedly connected to the upper end of the bottom plate 601. A first bidirectional threaded rod 603 is rotatably connected between the side plate 606 and the control box 2. There are two first bidirectional threaded rods 603. And a motor is arranged at one end of the first bidirectional threaded rod 603 away from the side plate 606. The motor is located inside the control box 2. A processing area 607 is arranged at the center of the side plate 606. The processing area 607 is a safe area for the device to process. A limiting block 604 is fixedly connected to the upper end of the bottom plate 601. The limiting block 604 is located on the central axis of the bottom plate 601. The limiting block 604 can limit the movement of the sliding plate 602 to prevent the sliding plate 602 from moving excessively and causing collision.

[0034] Please refer to Figure 10 and Figure 11 , the outer side of the first bidirectional threaded rod 603 is threadedly connected with a sliding plate 602. There are two groups of sliding plates 602. And the sliding plates 602 are symmetrically distributed with the limiting block 604 as the axis of symmetry. A positioning assembly 5 is fixedly connected to the upper end of each sliding plate 602. A first sliding rod 605 is fixedly connected between the side plate 606 and the control box 2. The first sliding rod 605 is fixedly connected to the limiting block 604. A top plate 608 is fixedly connected to the upper end of the side plate 606. The top plate 608 is fixedly connected to the water cutting assembly 7.

[0035] Specifically, the staff starts the motor, and the motor controls the rotation of the first bidirectional threaded rod 603. The rotation of the first bidirectional threaded rod 603 drives the two sliding plates 602 to move towards each other. When the sliding plates 602 move to a position where the steel can be placed above the two positioning components 5, the staff controls the motor to stop running. At this time, the steel is placed above the two positioning components 5. At the same time, when machining the narrower surface of the steel, the surface to be machined of the steel is placed face up on the limit block 604, and the motor is started at the same time. The motor controls the movement of the sliding plate 602. When the sliding plates 602 move until both sides of the two positioning components 5 are in contact with the steel, the motor stops running. At this time, the steel is clamped.

[0036] Please refer to Figure 11 , the water cutting assembly 7 includes an electric telescopic rod 702 fixedly connected to the work box 6. An infrared emitter 701 is arranged outside the electric telescopic rod 702. The infrared emitter 701 can project infrared rays to the lower end, enabling the staff to intuitively see the processing area of the steel and the safe working range according to the projection of the infrared rays on the steel, making the processing of the steel safer and more accurate. The infrared emitter 701 is fixedly connected to the work box 6. One end of the electric telescopic rod 702 away from the work box 6 is fixedly connected to a connecting column 705. One end of the connecting column 705 away from the electric telescopic rod 702 is fixedly connected to a water cutting head 703. A protective cover 704 is arranged outside the water cutting head 703. The distance between the end of the protective cover 704 and the end of the water cutting head 703 is the safe distance required during the processing of the water cutting head 703. By the contact between the protective cover 704 and the steel, the continuous movement of the electric telescopic rod 702 is restricted, so that the water cutting head 703 and the steel are always in a safe processing position, enabling the device to be applicable to steels of different thicknesses. The protective cover 704 is fixedly connected to the connecting column 705.

[0037] Specifically, when the electric telescopic rod 702 stops running, the infrared emitter 701 is in a working state. At this time, the infrared emitter 701 can project infrared rays onto the steel. At this time, the center point of the device and the safe processing area of the device will be displayed on the steel. The staff can judge whether the movement of the steel is in place and whether the processing is safe according to the distance between the point to be processed on the steel and the projection of the infrared emitter 701. When the electric telescopic rod 702 starts to work, the infrared emitter 701 stops running. At this time, the electric telescopic rod 702 drives the connecting column 705 to move until the protective cover 704 contacts the steel. At this time, the water cutting head 703 can punch holes in the steel.

[0038] Please refer to Figure 1 and Figure 2, a worm 504 is rotatably connected between two baffles 502. There are two worms 504. One end of the baffle 502 away from the worm 504 is provided with a first motor 501. The output ends of the first motor 501 are respectively fixedly connected to one of the worms 504. A turbine 505 is meshed between the worms 504. The upper end of the turbine 505 is fixedly connected to a rotating shaft 506. One side of the rotating shaft 506 away from the turbine 505 is rotatably connected to a sliding block 507. The two sides of the sliding block 507 are slidably connected to the first protective plate 519. Through the meshing between the worm 504 and the turbine 505, the rotation of the worm 504 can control the rotation of the turbine 505. Furthermore, by controlling the rotation direction and speed of the two worms 504, the movement, rotation and speed of the turbine 505 can be controlled, so that the sliding block 507 can move within a larger range, and thus the steel can be moved more conveniently, reducing the number of adjustments to the steel.

[0039] Please refer to Figures 3 to 6 , a limiting rod 503 is fixedly connected between the two baffles 502. The sliding block 507 is slidably connected to the limiting rod 503. The limiting rod 503 can limit the moving direction of the sliding block 507, making the movement of the sliding block 507 more stable. Furthermore, precise movement can be achieved, enhancing the accuracy of device processing. The upper end of the sliding block 507 is fixedly connected to a connecting plate 509. The rotating shaft 506 passes through the connecting plate 509. One end of the rotating shaft 506 away from the turbine 505 is fixedly connected to a gear 508. The gear 508 is slidably connected to the connecting plate 509. The upper end of the connecting plate 509 is fixedly connected to a first fixing block 515. A sliding rod 517 is slidably connected to the first fixing block 515. A rack is provided on one side of the sliding rod 517 close to the gear 508. The sliding rod 517 is meshed with the gear 508. One side of the gear 508 away from the first fixing block 515 is provided with a fixing block 514. The fixing block 514 is fixedly connected to the connecting plate 509. A first limiting rod 516 is slidably connected to the fixing block 514. Both ends of the first limiting rod 516 and the sliding rod 517 are fixedly connected to a fixing plate 510. Through the meshing between the sliding rod 517 and the gear 508, the movement of the fixing plate 510 is related to the rotation of the gear 508. Furthermore, the rotation direction of the worm 504 can control the movement of the fixing plate 510, making the movement of the device for the steel more convenient.

[0040] Specifically, the motor 501 controls the worm 504 to rotate. When the two worms 504 rotate in the same direction, the turbine 505 will not rotate. At the same time, the turbine 505 will move driven by the worm 504. The movement of the turbine 505 will drive the slider 507 to move through the rotating shaft 506, and then drive the fixed plate 510 to move on the first protective plate 519. When the two worms 504 rotate in opposite directions, the turbine 505 will rotate under the action of the worm 504. The rotation of the turbine 505 will drive the gear 508 to rotate through the rotating shaft 506. The rotation of the gear 508 will drive the sliding rod 517 to move, so that the fixed plate 510 can move. The movable range of the fixed plate 510 is increased, improving the convenience of the device for moving steel.

[0041] Please refer to Figure 7 and Figure 8 As shown in, the clamping assembly 513 includes a connecting block 521 fixedly connected to the fixed plate 510. A sliding groove is provided inside the connecting block 521. Two threaded rods 523 are rotatably connected at the sliding groove. A first sliding block 524 is threadedly connected to the outer side of the threaded rod 523. One end of the first sliding block 524 away from the fixed plate 510 is fixedly connected to a first fixed plate 522. The first fixed plate 522 is slidably connected to the connecting block 521. A transverse clamping plate 520 is fixedly connected to the upper end of the first fixed plate 522. A first trigger block is provided at one end of the transverse clamping plate 520 close to the side pressing plate 511. Two bidirectional threaded rods 525 are rotatably connected inside the transverse clamping plate 520. A longitudinal clamping plate 526 is threadedly connected to the outer side of the bidirectional threaded rod 525. The longitudinal clamping plate 526 is slidably connected to the first fixed plate 522. A second trigger block is provided at the opposite ends of the longitudinal clamping plate 526. By rotating the threaded rod 523, the first sliding block 524 can be driven to move, and then the transverse clamping plate 520 can be driven by the first sliding block 524 to move, clamping the two ends of the steel. At the same time, by rotating the bidirectional threaded rod 525, the longitudinal clamping plate 526 is driven to move, clamping the two sides of the steel, so that the steel is fixed.

[0042] Please refer to Figure 9 As shown in, a threaded rod 527 is rotatably connected inside the longitudinal clamping plate 526. An upper clamping plate 528 is threadedly connected to the outer side of the threaded rod 527. The upper clamping plate 528 is slidably connected to the transverse clamping plate 520. A third trigger block is provided at the lower end of the upper clamping plate 528. By rotating the threaded rod 527, the upper clamping plate 528 can move, so that the transverse clamping plate 520 can move synchronously, clamping the upper end of the steel, preventing the steel from shifting during processing and affecting the processing accuracy.

[0043] Specifically, when the steel is placed on the fixed plate 510, the steel contacts the side pressing plate 511 at this time, and there is a gap between the steel and the connecting block 521. At this time, the threaded rod 523 rotates, causing the sliding block 524 to drive the transverse clamping plate 520 to move. When the two transverse clamping plates 520 move to be in close contact with the steel, the threaded rod 523 stops moving. At this time, both ends of the steel are fixed. At the same time, the bidirectional threaded rod 525 rotates, and the rotation of the bidirectional threaded rod 525 drives the two longitudinal clamping plates 526 to move. Similarly, when the two longitudinal clamping plates 526 are both in close contact with the steel, the bidirectional threaded rod 525 stops operating. At this time, both sides of the steel are fixed. At the same time, the threaded rod 527 starts to rotate, and the rotation of the threaded rod 527 drives the upper clamping plate 528 to move. Similarly, when the upper clamping plate 528 contacts the steel, it stops operating. At this time, the upper and lower ends of the steel are fixed, effectively preventing the occurrence of offset during the processing of the steel.

[0044] Working principle of the present invention: When fixed-point punching is required, the staff starts the motor, and the motor controls the rotation of the bidirectional threaded rod 603. The rotation of the bidirectional threaded rod 603 drives the two sliding plates 602 to move towards each other. When the sliding plates 602 move to a position where the steel can be placed above the two positioning components 5, the staff controls the motor to stop operating. At this time, the steel is placed above the two positioning components 5. When the steel is placed on the fixed plate 510, the steel contacts the side pressing plate 511 at this time, and there is a gap between the steel and the connecting block 521. At this time, the threaded rod 523 rotates, causing the sliding block 524 to drive the transverse clamping plate 520 to move. When the two transverse clamping plates 520 move to be in close contact with the steel, the threaded rod 523 stops moving. At this time, both ends of the steel are fixed. At the same time, the bidirectional threaded rod 525 rotates, and the rotation of the bidirectional threaded rod 525 drives the two longitudinal clamping plates 526 to move. Similarly, when the two longitudinal clamping plates 526 are both in close contact with the steel, the bidirectional threaded rod 525 stops operating. At this time, both sides of the steel are fixed. At the same time, the threaded rod 527 starts to rotate, and the rotation of the threaded rod 527 drives the upper clamping plate 528 to move. Similarly, when the upper clamping plate 528 contacts the steel, it stops operating. At this time, the upper and lower ends of the steel are fixed. When the staff places the steel on the positioning component 5 and the processing position of the steel coincides with the positioning component 5, the staff can control the reverse rotation of the bidirectional threaded rod 603. The reverse rotation of the bidirectional threaded rod 603 drives the two positioning components 5 to move in the reverse direction through the sliding plates 602, and at the same time controls the synchronous rotation of the threaded rod 523, so that the transverse clamping plate 520 continues to advance to clamp the steel, thereby keeping the position of the steel unchanged and reducing the overlapping part between the positioning component 5 and the steel.

[0045] After the steel is fixed, the central axis of the steel coincides with the central axis of the device. The staff controls the operation of the first motor 501 according to the position difference between the position where the steel needs to be processed and the midpoint of the steel. The first motor 501 controls the worm 504 to rotate. When the two worms 504 rotate in the same direction, the turbine 505 will not rotate. At the same time, the turbine 505 will move under the drive of the worm 504. The movement of the turbine 505 will drive the slider 507 to move through the rotating shaft 506, and then drive the fixed plate 510 to move on the first protective plate 519. When the two worms 504 rotate in opposite directions, the turbine 505 will rotate under the action of the worm 504. The rotation of the turbine 505 will drive the gear 508 to rotate through the rotating shaft 506. The rotation of the gear 508 will drive the sliding rod 517 to move, so that the fixed plate 510 can move, making the processing point of the steel located at the center of the device. At the same time, the infrared emitter 701 can project infrared rays onto the steel. At this time, the center point of the device and the safe processing area of the device will be displayed on the steel. The staff can judge whether the movement of the steel is in place and whether the processing is safe according to the distance between the point to be processed on the steel and the projection of the infrared emitter 701. When the steel moves to the specified position, the infrared emitter 701 will stop emitting infrared rays. At the same time, when the electric telescopic rod 702 starts to work, the electric telescopic rod 702 will drive the connecting column 705 to move until the protective cover 704 contacts the steel. At this time, the water cutting head 703 can punch holes in the steel, and sufficient safety space is reserved at both the upper and lower ends of the steel during the entire punching process;

[0046] When punching can be performed at any position on the steel, it is only necessary to control the punching point of the steel to be within the range of the processing area 607 after the steel is fixed. When processing the narrow surface of the steel, place the surface of the steel to be processed face up on the limit block 604, and start the motor at the same time. The motor controls the sliding plate 602 to move. When the sliding plate 602 moves until both sides of the two positioning components 5 are in contact with the steel, stop running. At this time, both sides of the steel are clamped by the side pressing plates 511, and then the side pressing plates 511 are controlled by the first motor 501 to move, driving the steel to move to the specified position for processing.
