Description

Technical Field

[0001] The present invention relates to the technical field of steel plate processing, and particularly relates to an anti-bending mechanism for steel plate processing. Background Art

[0002] Steel plates are flat steel materials cast from molten steel and pressed after cooling. They are flat and rectangular, and can be directly rolled or cut from wide steel strips.

[0003] ‌The main reasons for anti-bending processing of steel plates include preventing the steel plates from bending during processing, ensuring the processing quality and finished product quality, thus making the anti-bending work of steel plates an indispensable step in the steel plate processing process.

[0004] The existing devices have the following deficiencies:

[0005] 1. It can only locally press against the four sides of the steel plate, and at the same time, the four corners of the steel plate cannot be limited, so it is easy to displace during anti-bending processing, reducing the processing accuracy.

[0006] 2. It cannot simultaneously limit the four sides and four corners of the steel plate synchronously, and the clamping efficiency is low, thus increasing the overall time-consuming of the anti-bending processing of the steel plate and reducing the processing efficiency.

[0007] 3. The existing devices cannot perform anti-bending processing on steel plates of different sizes, so they cannot meet the anti-bending processing requirements of steel plates of different sizes, and the flexibility and practicality of the devices need to be improved.

[0025] The beneficial effects of the present invention are as follows:

[0026] 1. By designing the transmission component, the present invention can realize the synchronous operation of the pressing device and the limiting device, that is, when the four pressing plates approach each other and press against the four sides of the steel plate, the four L-shaped stop blocks descend synchronously to limit the four corners of the steel plate, so as to limit all the edges of the whole steel plate and prevent it from displacing during processing, which is beneficial to improving the accuracy of anti-side bending processing.

[0027] 2. By designing the transmission component, the present invention can realize the synchronous operation of the pressing device and the limiting device, that is, when the four pressing plates approach each other and press against the four sides of the steel plate, the four L-shaped stop blocks descend synchronously to limit the four corners of the steel plate, so as to limit all the edges of the whole steel plate. Just place the steel plate horizontally on the four overlapping blocks on the top of the feeding table, without the need for manual clamping and positioning, which significantly improves the clamping efficiency of the steel plate, and further greatly reduces the overall time-consuming of the anti-side bending processing of the steel plate and improves the processing efficiency.

[0028] 3. By designing the second embodiment, the present invention can make each pressing plate slide with different strokes through the cooperation of four lead screws, four sliding plates and eight push rods, which is convenient for pressing steel plates with different lengths and widths, so as to meet the anti-side bending processing of steel plates with different sizes and improve the flexibility and practicability of the mechanism.

[0029] 4. By designing an L-shaped limiting block on the top of each overlapping block, when the bottoms of the four L-shaped stop blocks are attached to the tops of the four overlapping blocks, the four L-shaped limiting blocks are vertically inserted into the interiors of the four L-shaped slots, so as to lock the four L-shaped stop blocks and prevent them from displacing during the anti-side bending processing, improve the limiting stability of the L-shaped stop blocks to the corners of the steel plate, and further improve the processing accuracy.

[0030] 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.

[0031] 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

Detailed implementation manners

[0045] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and specific implementation manners.

[0046] Among them, the accompanying drawings are only for illustrative purposes, showing only schematic diagrams, not physical diagrams, and should not be construed as a limitation to the present invention; in order to better illustrate the embodiments of the present invention, some components in the drawings will be omitted, enlarged or reduced, and do not represent the dimensions of the actual product.

[0047] Embodiment 1: The present invention provides a technical solution. Referring to Figures 1 to 10 as shown, a anti-side bending mechanism for steel plate processing includes a base 1, and the base 1 is horizontally arranged;

[0048] It further includes a controller, a feeding table 2, a stamping device 3, a pressing device 4 and a limiting device 5;

[0049] The feeding table 2 is fixedly arranged on the top of the base 1;

[0050] The stamping device 3 is arranged on the top of the base 1. The stamping device 3 includes a support frame 6 and a downward pressing component 7. The support frame 6 is fixedly arranged on the top of the base 1, and the downward pressing component 7 is inserted into the support frame 6;

[0051] The pressing device 4 is arranged on the top of the base 1. The pressing device 4 includes a driving component 8, four pressing plates 9 and four pushing components. The driving component 8 is arranged on the top of the base 1, and the four pushing components are symmetrically arranged on the outer wall of the feeding table 2, and each pressing plate 9 is fixedly arranged on a pushing component;

[0052] The limiting device 5 is arranged on the top of the base 1. The limiting device 5 includes a transmission component 10, a connection component 11, four L-shaped stoppers 12 and four support rods 13. The four support rods 13 are all fixedly arranged on the top of the base 1. Each L-shaped stopper 12 is slidably arranged on the top of a support rod 13 through two guide rods. The connection component 11 is arranged between the four L-shaped stoppers 12. The transmission component 10 is arranged between the pushing component and the connection component 11 to drive the four L-shaped stoppers 12 to move up and down. The pressing component 7 and the driving component 8 are both electrically connected to the controller.

[0053] Referring to Figures 1 to 10 As shown in the figure, the driving component 8 includes a mounting block 14, a first cylinder 15 and a push block 16. The mounting block 14 is fixedly arranged on the top of the base 1. The first cylinder 15 is hinged on the top of the mounting block 14. The push block 16 is hinged on the output end of the first cylinder 15. The first cylinder 15 is electrically connected to the controller. When performing anti-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. Then start the first cylinder 15 through the controller, so that its output end contracts. Since its output end is hinged to one end of the push block 16, the push block 16 is driven to pull towards the end away from the feeding table 2.

[0054] Referring to Figures 1 to 10 As shown in the figure, each pushing component includes a first connecting rod 17, a sliding rod 18 and a limiting plate 19. The limiting plate 19 is fixedly arranged on the outer wall of the feeding table 2. The sliding rod 18 is slidably arranged on the top of the limiting plate 19. The first connecting rod 17 is arranged in contact with the end of the sliding rod 18 away from the limiting plate 19. Each pressing plate 9 is fixedly connected to the end of a sliding rod 18 away from the first connecting rod 17. A second connecting rod 20 is hinged between every two adjacent first connecting rods 17. Four overlapping blocks 21 are symmetrically arranged at the four corners of the top of the feeding table 2. Each second connecting rod 20 is hinged to an overlapping block 21. 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 pulls towards the end away from the feeding 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 limiting plate 19, the first connecting rod 17 is arranged in contact with the end of the sliding rod 18 away from the limiting plate 19, each pressing plate 9 is fixedly connected to the end of a sliding rod 18 away from the first connecting rod 17, a second connecting rod 20 is hinged between every two adjacent first connecting rods 17, and each second connecting rod 20 is hinged to an overlapping block 21, the first connecting rod 17 is driven to slide obliquely towards the end close to the feeding table 2. At the same time, the contact force generated by the oblique sliding of the first connecting rod 17 on the sliding rod 18 drives the pressing plate 9 to move towards the end close to the edge of the steel plate. Cooperating with the other three pushing components, the four sides of the steel plate are tightened.

[0055] Referring to Figures 1 to 10As shown, a return spring 22 is sleeved on the outer wall of each sliding rod 18. The outer wall of each limiting plate 19 and the outer wall of each first connecting rod 17 are respectively in contact with two ends of a return spring 22. The return spring 22 contracts when the first connecting rod 17 slides obliquely towards the end facing the feeding table 2, and automatically drives the sliding rod 18 and the first connecting rod 17 to reset when the output end of the first air cylinder 15 resets, thereby driving the pressing plate 9 to reset, which facilitates the next pressing operation.

[0056] Referring to Figures 1 to 10 As 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 rotating shaft. Both telescopic rods 26 are arranged on the top of the base 1. The lifting plate 25 is fixedly arranged at the top ends 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 formed on the outer wall of the traction plate 24. The outer wall of the roller 23 is attached to the inner wall of the inclined groove 27. While the pressing plate 9 presses the edge of the steel plate, since the roller 23 is rotatably connected to one of the first connecting rods 17 through a rotating shaft, 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. Therefore, while the first connecting rod 17 slides obliquely towards the end facing the feeding table 2, the first connecting rod 17 drives the roller 23 to slide obliquely inside the inclined groove 27, and thus drives the lifting plate 25 and the traction plate 24 at its bottom to descend through the frictional force generated between the roller 23 and the inclined groove 27 during the oblique sliding of the roller 23.

[0057] Referring to Figures 1 to 10 As shown, the connection assembly 11 includes four cross bars 28. Each cross bar 28 is fixedly arranged between two adjacent L-shaped stoppers 12. When the lifting plate 25 and the traction plate 24 at its bottom descend, since each cross bar 28 is fixedly connected to two adjacent L-shaped stoppers 12, and each L-shaped stopper 12 is slidably connected to a support rod 13 through two guide rods, four L-shaped stoppers 12 are driven to descend vertically and synchronously through the four cross bars 28 until the bottoms of the four L-shaped stoppers 12 are in contact with the tops of the four overlapping blocks 21, realizing the synchronous limit of the four corners of the steel plate.

[0058] Referring to Figures 1 to 10As 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.

[0059] Reference Figures 1 to 10 As 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.

[0060] 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.

[0061] 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.

[0062] When the pushing block 16 is pulled towards the end away from the feeding table 2, since the pushing 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 limiting plate 19, the first connecting rod 17 is in contact with the end of the sliding rod 18 away from the limiting plate 19, each pressing 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 lapping block 21. Thus, the first connecting rod 17 slides obliquely towards the end towards the feeding table 2. At the same time, the contact force generated by the oblique sliding of the first connecting rod 17 on the sliding rod 18 drives the pressing plate 9 to approach the end close to the edge of the steel plate, and together with the other three pushing components, the four sides of the steel plate are tightly pressed.

[0063] The return spring 22 contracts when the first connecting rod 17 slides obliquely towards the end towards the feeding table 2, and automatically drives the sliding rod 18 and the first connecting rod 17 to return when the output end of the first cylinder 15 returns, thereby driving the pressing plate 9 to return, which is convenient for the next pressing operation.

[0064] While the pressing plate 9 presses against the edge of the steel plate, since the roller 23 is rotatably connected to one of the first connecting rods 17 through a rotating shaft, the lifting plate 25 is fixedly connected to the tops of 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. Thus, while the first connecting rod 17 slides obliquely towards the end towards the feeding table 2, the first connecting rod 17 drives the roller 23 to slide obliquely inside the inclined groove 27, and the contact force generated by the oblique sliding of the roller 23 and the inclined groove 27 drives the lifting plate 25 and the traction plate 24 at its bottom to descend.

[0065] When the lifting plate 25 and the traction plate 24 at its bottom descend, since each cross bar 28 is fixedly connected to two adjacent L-shaped stoppers 12, and each L-shaped stopper 12 is slidably connected to a support rod 13 through two guide rods, the four L-shaped stoppers 12 are driven to descend vertically synchronously by the four cross bars 28 until the bottoms of the four L-shaped stoppers 12 are in contact with the tops of the four lapping blocks 21, realizing the synchronous limit of the four corners of the steel plate. It should be noted that when the bottoms of the four L-shaped stoppers 12 are in contact with the tops of the four lapping blocks 21, the four L-shaped limit blocks 34 are vertically inserted into the interiors of the four L-shaped grooves, so that the four L-shaped stoppers 12 cannot displace during the anti-bending processing, improving the processing accuracy.

[0066] 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.

[0067] 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.

[0068] Embodiment 2: In order to facilitate the mechanism to perform anti-lateral bending processing on steel plates of different sizes;

[0069] The present invention provides another technical solution, referring to Figure 11 As 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.
