[0018] Beneficial effects of the present invention: 1. The present invention realizes the synchronous operation of the clamping device and the limiting device by designing the transmission component, that is, when the four clamping plates approach each other and clamp the four edges of the steel plate, the four L-shaped stoppers descend synchronously to limit the four corners of the steel plate, thereby limiting all the edges of the entire steel plate to prevent displacement during processing, which is beneficial to improving the accuracy of the anti-side bending processing.

[0019] 2. The present invention can realize the synchronous operation of the clamping device and the limiting device by designing the transmission component, that is, when the four clamping plates approach each other and clamp the four sides of the steel plate, the four L-shaped stoppers descend synchronously to limit the four corners of the steel plate, thereby limiting all the edges of the entire steel plate. The steel plate only needs to be placed horizontally on the four overlapping blocks on the top of the discharge table, and there is no need for manual clamping and positioning. The clamping efficiency of the steel plate is significantly improved, thereby greatly reducing the overall time consumption of the steel plate anti-lateral bending processing and improving the processing efficiency.

[0020] 3. By designing the second embodiment, the present invention can make each clamping plate slide with a different stroke through the cooperation of four screw rods, four slide plates and eight push rods, so as to facilitate the clamping of steel plates of different lengths and widths, thereby meeting the anti-lateral bending processing of steel plates of different sizes, thereby improving the flexibility and practicality of the mechanism.

[0021] 4. The present invention designs an L-shaped limit block on the top of each overlapping block. When the bottom of the four L-shaped limit blocks are in contact with the top of the four overlapping blocks, the four L-shaped limit blocks are vertically inserted into the four L-shaped grooves, thereby locking the four L-shaped limit blocks so that they cannot be displaced during the anti-lateral bending processing, thereby improving the stability of the L-shaped limit blocks on the edges and corners of the steel plates and further improving the processing accuracy.

[0022] 5. The present invention designs a third cylinder and a push plate. When the anti-lateral bending processing of the steel plate is completed, the output end of the first cylinder is extended through control, that is, reset, so that the four clamping plates are moved away from each other and the four sides of the steel plate are loosened. Since the four L-shaped blocks and the four clamping plates are linked by the transmission component, the four L-shaped blocks rise synchronously to loosen the four corners of the steel plate. Then, the third cylinder is started by the controller to make its output end extend upward. Since its output end is fixedly connected to the push plate, the push plate is driven to extend vertically upward, and the processed steel plate is pushed out from between the four L-shaped limit blocks, which is convenient for material removal.

[0023] 6. The present invention realizes the synchronous operation of the clamping device and the limiting device by designing the transmission component, thereby preventing each device from operating independently, reducing the amount of driving power used by the mechanism, reducing the power consumption of the mechanism, and thus helping to reduce the cost of anti-lateral bending processing. At the same time, the overall structure of the mechanism is reduced, reducing the cost and occupied space. BRIEF DESCRIPTION OF THE DRAWINGS

The first cylinder 15 is electrically connected to the controller. When anti-lateral bending processing is performed, the steel plate is first placed horizontally on the top of the four overlap blocks 21, and the four corners of the steel plate are kept in contact with the four L-shaped limit blocks 34. Then, the first cylinder 15 is started by the controller to shrink its output end. Since its output end is hinged to one end of the push block 16, the push block 16 is pulled toward the end away from the discharge table 2.

[0030] Reference Figures 1 to 10 As shown, each pushing assembly includes a first connecting rod 17, a sliding rod 18 and a limiting plate 19.

The push block 16 is hinged to one of the first connecting rods 17 close to the first cylinder 15. When the push block 16 is pulled toward the end away from the discharge table 2, due to The push block 16 is hinged to one of the first connecting rods 17 close to the first cylinder 15, the sliding rod 18 is slidably connected to the top of the limit plate 19, the first connecting rod 17 is fitted with the end of the sliding rod 18 away from the limit plate 19, each clamping plate 9 is fixedly connected to the end of a sliding rod 18 away from the first connecting rod 17, and a second connecting rod 20 is hingedly designed between every two adjacent first connecting rods 17, and each second connecting rod 20 is hinged to a lap block 21, so that the first connecting rod 17 slides obliquely toward one end of the unloading table 2, and at the same time, the resistance force generated on the sliding rod 18 when the first connecting rod 17 slides obliquely drives the clamping plate 9 to approach the end close to the edge of the steel plate, and cooperates with the other three pushing components to achieve clamping of the four sides of the steel plate.

[0031] Reference Figures 1 to 10 As shown, a return spring 22 is sleeved on the outer wall of each slide rod 18, and the outer wall of each limit plate 19 and the outer wall of each first connecting rod 17 respectively abut against the two ends of a return spring 22. The return spring 22 contracts when the first connecting rod 17 slides obliquely toward one end of the unloading table 2, and automatically drives the slide rod 18 and the first connecting rod 17 to reset when the output end of the first cylinder 15 is reset, thereby driving the clamping plate 9 to reset, facilitating the next clamping operation.

[0032] Reference Figures 1 to 10As shown, the transmission assembly 10 includes a roller 23, a traction plate 24, a lifting plate 25 and two telescopic rods 26. The roller 23 is rotatably arranged on the outer wall of one of the first connecting rods 17 through a hinge shaft. The two telescopic rods 26 are both arranged on the top of the base 1. The lifting plate 25 is fixedly arranged on the top of the two telescopic rods 26. The traction plate 24 is fixedly arranged at the bottom of the lifting plate 25. An inclined groove 27 is opened on the outer wall of the traction plate 24. The outer wall of the roller 23 is fitted with the inner wall of the inclined groove 27. When the pressing plate 9 presses against the edge of the steel plate, the roller 23 is hinged. The connecting shaft is hinged to one of the first connecting rods 17, the lifting plate 25 is fixedly connected to the top ends of the two telescopic rods 26, the traction plate 24 is fixedly connected to the bottom of the lifting plate 25, and an inclined groove 27 for the roller 23 to slide is designed on the outer wall of the traction plate 24, so that when the first connecting rod 17 slides obliquely toward one end of the discharge table 2, the roller 23 is driven by the first connecting rod 17 to slide obliquely inside the inclined groove 27, so that the lifting plate 25 and the traction plate 24 at the bottom thereof are driven to descend through the resistance force generated by the oblique sliding of the roller 23 and the inclined groove 27.

[0033] Reference Figures 1 to 10 As shown, the connecting assembly 11 includes four cross bars 28, each of which is fixedly arranged between two adjacent L-shaped blocks 12. When the lifting plate 25 and the traction plate 24 at the bottom thereof are lowered, since each cross bar 28 is fixedly connected to two adjacent L-shaped blocks 12, each L-shaped block 12 is slidably connected to a support rod 13 through two guide rods, the four L-shaped blocks 12 are driven to descend vertically and synchronously through the four cross bars 28 until the bottom of the four L-shaped blocks 12 are in contact with the top of the four overlap blocks 21, thereby realizing the synchronous limiting of the four corners of the steel plate.

[0034] Reference Figures 1 to 10 As shown, the pressing assembly 7 includes a second cylinder 29, a pressing plate 30 and two limit rods 31. The second cylinder 29 is inserted into the top of the support frame 6, and the pressing plate 30 is fixed on its output end. The two limit rods 31 are inserted into the support frame 6, and the bottom ends of the two limit rods 31 are fixedly connected to the top of the pressing plate 30. The second cylinder 29 is electrically connected to the controller. When the four corners and four sides of the steel plate are fixed, the second cylinder 29 is started by the controller so that its output end extends downward. Since the pressing plate 30 is fixedly connected to its output end, the two limit rods 31 are inserted into the support frame 6, and the bottom ends of the two limit rods 31 are fixedly connected to the top of the pressing plate 30, thereby driving the pressing plate 30 to descend vertically, pressing the steel plate to achieve anti-lateral bending processing.

[0035] Reference Figures 1 to 10As shown, a third cylinder 32 is inserted inside the unloading table 2, and a push plate 33 is fixed on its output end. The third cylinder 32 is electrically connected to the controller. When the anti-lateral bending processing of the steel plate is completed, the output end of the first cylinder 15 is extended through control, that is, reset, so that the four clamping plates 9 are separated from each other, and the four sides of the steel plate are loosened. Since the four L-shaped stoppers 12 and the four clamping plates 9 are linked by the transmission assembly 10, the four L-shaped stoppers 12 rise synchronously to loosen the four corners of the steel plate. Then the third cylinder 32 is started by the controller to make its output end extend upward. Since its output end is fixedly connected to the push plate 33, the push plate 33 is driven to extend vertically upward, and the processed steel plate is pushed out from between the four L-shaped limit blocks 34, which is convenient for material removal.

[0036] Reference Figures 1 to 10 As shown, an L-shaped limit block 34 is fixedly provided on the top of each overlap block 21, and an L-shaped slot 35 is provided on the bottom of each L-shaped stop block 12 for inserting the L-shaped limit block 34. When the bottom of the four L-shaped stop blocks 12 are in contact with the top of the four overlap blocks 21, the four L-shaped limit blocks 34 are vertically inserted into the four L-shaped slots, so that the four L-shaped stop blocks 12 cannot be displaced during the anti-lateral bending processing, thereby improving the processing accuracy.

[0037] Working principle: When performing anti-lateral bending processing, first place the steel plate horizontally on the top of the four overlapping blocks 21, and keep the four corners of the steel plate in contact with the four L-shaped limit blocks 34, and then start the first cylinder 15 through the controller to shrink its output end. Since its output end is hinged to one end of the push block 16, it drives the push block 16 to be pulled toward the end away from the unloading table 2.

[0038] When the push block 16 is pulled toward the end away from the unloading table 2, since the push block 16 is hinged to one of the first connecting rods 17 close to the first cylinder 15, the sliding rod 18 is slidably connected to the top of the limit plate 19, the first connecting rod 17 is in contact with the end of the sliding rod 18 away from the limit plate 19, and each clamping plate 9 is fixedly connected to an end of a sliding rod 18 away from the first connecting rod 17, and a second connecting rod 20 is hingedly designed between every two adjacent first connecting rods 17, and each second connecting rod 20 is hinged to a lap block 21, so that the first connecting rod 17 slides obliquely toward one end of the unloading table 2, and at the same time, the resistance force generated on the sliding rod 18 when the first connecting rod 17 slides obliquely drives the clamping plate 9 to approach the end close to the edge of the steel plate, and cooperates with the other three pushing components to achieve clamping of the four sides of the steel plate.

[0039] The reset spring 22 contracts when the first connecting rod 17 slides obliquely toward one end of the unloading table 2, and automatically drives the slide rod 18 and the first connecting rod 17 to reset when the output end of the first cylinder 15 resets, thereby driving the clamping plate 9 to reset, facilitating the next clamping operation.

[0040] While the clamping plate 9 is clamping the edge of the steel plate, since the roller 23 is hinged to one of the first connecting rods 17 through the hinge shaft, the lifting plate 25 is fixedly connected to the top ends of the two telescopic rods 26, and the traction plate 24 is fixedly connected to the bottom of the lifting plate 25. The outer wall of the traction plate 24 is designed with an inclined groove 27 for the roller 23 to slide, so that when the first connecting rod 17 slides obliquely toward one end of the discharge table 2, the roller 23 is driven by the first connecting rod 17 to slide obliquely inside the inclined groove 27, so that the lifting plate 25 and the traction plate 24 at the bottom are driven to descend through the resistance force generated by the roller 23 and the inclined groove 27 when it slides obliquely.

[0041] When the lifting plate 25 and the traction plate 24 at the bottom of it descend, since each cross bar 28 is fixedly connected to two adjacent L-shaped blocks 12, each L-shaped block 12 is slidably connected to a support rod 13 through two guide rods, the four cross bars 28 drive the four L-shaped blocks 12 to descend vertically and synchronously until the bottom of the four L-shaped blocks 12 are in contact with the top of the four overlap blocks 21, thereby realizing the synchronous limiting of the four corners of the steel plate. It should be noted that when the bottom of the four L-shaped blocks 12 are in contact with the top of the four overlap blocks 21, the four L-shaped limit blocks 34 are vertically inserted into the four L-shaped grooves, so that the four L-shaped blocks 12 cannot be displaced during the anti-lateral bending processing, thereby improving the processing accuracy.

[0042] When the four corners and four sides of the steel plate are fixed, the second cylinder 29 is started through the controller, so that its output end extends downward. Since the pressing plate 30 is fixedly connected to its output end, the two limit rods 31 are plugged into the support frame 6, and the bottom ends of the two limit rods 31 are fixedly connected to the top of the pressing plate 30, thereby driving the pressing plate 30 to descend vertically, pressing the steel plate to achieve anti-lateral bending processing.

[0043] When the anti-lateral bending processing of the steel plate is completed, the output end of the first cylinder 15 is extended through control, that is, reset, so that the four clamping plates 9 are moved away from each other and the four sides of the steel plate are loosened. Since the four L-shaped stoppers 12 and the four clamping plates 9 are linked by the transmission assembly 10, the four L-shaped stoppers 12 rise synchronously to loosen the four corners of the steel plate. Then the third cylinder 32 is started by the controller to make its output end extend upward. Since its output end is fixedly connected to the push plate 33, the push plate 33 is driven to extend vertically upward, and the processed steel plate is pushed out from between the four L-shaped limit blocks 34, which is convenient for material removal.

[0044] Embodiment 2: In order to facilitate the mechanism to perform anti-lateral bending processing on steel plates of different sizes; The present invention provides another technical solution, referring to Fig.11As shown, each pushing assembly includes a support plate 36, a micro motor 37, a screw 38, a slide plate 39 and two push rods 40. The support plate 36 is fixedly arranged on the outer wall of the unloading platform 2. Two vertical plates are fixedly arranged on the top of the support plate 36. The screw 38 is rotatably arranged between the two vertical plates. Two guide rods are fixedly arranged between the two vertical plates. The slide plate 39 is slidably arranged on the outer walls of the two guide rods, and the slide plate 39 is threadedly connected to the screw 38. The micro motor 37 is fixedly arranged on the outer wall of one of the vertical plates, and its output end is fixedly connected to one end of the screw 38. The two push rods 40 are respectively fixedly arranged on the outer walls of the two ends of the slide plate 39, and the abutment plate 9 is fixed to the end of the two push rods 40 away from the slide plate 39. The micro motor 37 is electrically connected to the controller. When anti-lateral bending processing is performed on steel plates of different lengths and widths, the steel plates are first placed horizontally on the top of the four overlapping blocks 21 through the controller, and then the micro motor 37 is started through the controller, so that it drives the screw rod 38 to rotate. Since the slide plate 39 is threadedly connected to the screw rod 38, the slide plate 39 is slidingly connected to the two guide rods. At the same time, the slide plate 39 is fixedly connected to the clamping plate 9 through two push rods 40, thereby driving the clamping plate 9 to slide toward one end close to the edge of the steel plate to achieve clamping of the edge of the steel plate, and then the anti-lateral bending processing is performed through the pressing plate 30, thereby meeting the anti-lateral bending processing of steel plates of different sizes, thereby improving the flexibility and practicality of the mechanism.
