Description

Technical Field

[0001] The utility model relates to the technical field of metal plate turning, in particular to a metal plate turning tooling. Background Art

[0002] When existing factories process large mechanical products, each component needs to be processed. Even for parts, most components are very heavy. During the process of turning over a metal plate, a turning tooling is required.

[0003] A Chinese patent with the publication number CN107298373A discloses a special turning tooling for thick plates, including a main suspension rod, an auxiliary hook, and a fixed clamping plate. The auxiliary hook is welded to the lower end of the main suspension rod. The fixed clamping plate is fixed to the upper end of the main suspension rod during use. Two bolt holes are provided on both the fixed clamping plate and the main suspension rod. The distance between the two bolt holes on the fixed clamping plate is the same as the distance between the two bolt holes on the main suspension rod. The four bolt holes are of the same size. The fixed clamping plate and the main suspension rod are fixed together by bolts, nuts, and gaskets during use. An auxiliary hook hole is provided on the auxiliary hook, and a main hook hole is provided on the main suspension rod. The main hook hole is located above the two bolt holes. The fixed clamping plate is in a right-angled shape. The advantages of the present invention are: accelerating the turning speed of the thick plate, improving work efficiency, increasing the safety factor during the implementation process, and not causing wear to the thick plate base material during the implementation of the tooling.

[0004] When the existing turning tooling turns over a metal plate, it usually uses a steel wire rope to obliquely pull the metal plate for turning. However, during the oblique pulling process, the metal plate is prone to center of gravity deviation, resulting in position movement and poor stability of the metal plate. Therefore, a metal plate turning tooling is proposed to solve the above problems. Content of the Utility Model

[0005] In order to make up for the deficiencies of the existing technology and solve the problems existing in the existing technology, the utility model proposes a metal plate turning tooling.

[0006] The technical solution adopted by the present utility model to solve its technical problems is as follows: A metal plate turning tooling of the present utility model includes a base. Two groups of support rods are installed on the base, and a fixed rod is installed between the two groups of support rods. A lifting block is slidably connected to one of the support rods. A guiding rod is installed on the lifting block, and a sliding groove is formed in the guiding rod. A first lead screw is rotatably installed between the inner walls of the sliding groove. A handwheel is connected to the first lead screw. The thread directions on the first lead screw are symmetrically opposite. Two groups of sliders are symmetrically assembled in the sliding groove. The sliders are slid by cooperating with the first lead screw through threads. A clamping plate is installed on the slider. A rotating block is rotatably installed on the inner wall of the clamping plate. A lifting groove is formed in the support rod. A second lead screw is rotatably installed on the inner wall of the lifting groove. A first stepping motor is installed on the fixed rod through a machine base. The output shaft of the first stepping motor is connected to the second lead screw. The lifting block is assembled in the lifting groove. The lifting block is sleeved around the second lead screw. The lifting block is slid by cooperating with the second lead screw through threads. By driving two groups of rotating blocks to move relatively synchronously through two groups of clamping plates, the center of gravity of the metal plate is clamped and fixed by the two groups of rotating blocks. During the turning process, one end of the metal plate with a lifting ring is turned over, and the other end of the metal plate is fixedly clamped by the two groups of rotating blocks. The rotating block can rotate on the clamping plate. Therefore, the metal plate rotates with the central axis of the rotating block as the rotation axis, and the center of gravity of the metal plate does not shift, avoiding the position movement of the metal plate, which is beneficial to improving the stability of the metal plate.

[0007] Preferably, a metal plate is placed on the base, and a lifting ring is installed on the metal plate. A moving groove is formed in the fixed rod. A third lead screw is rotatably installed on the inner wall of the moving groove. A second stepping motor is installed on the side wall of the fixed rod through a machine base. The output shaft of the second stepping motor is fixedly connected to one end of the third lead screw. A moving block is assembled in the moving groove. A hydraulic cylinder is installed at the bottom end of the moving block. A hydraulic rod is connected to the hydraulic cylinder. A steel wire rope is connected to the hydraulic rod. A hook is connected to the steel wire rope. By hooking the hook on the lifting ring of the metal plate, the steel wire rope is driven to move vertically upward by the hydraulic rod. At the same time, the steel wire rope is driven to move from right to left by the hydraulic rod. The steel wire rope obliquely pulls the metal plate, so that the metal plate is turned over. The hydraulic rod drives the steel wire rope to move vertically downward, and the steel wire rope places the metal plate on the base, realizing the turning of the metal plate, which is beneficial to improving the turning efficiency.

[0008] The beneficial effects of the present utility model are as follows:

[0009] 1. The utility model drives two sets of rotating blocks to move synchronously and relatively through two sets of clamping plates, so that the two sets of rotating blocks clamp and fix the center of gravity of the metal plate. During the turning process, one end of the metal plate with a lifting ring rotates, and the other end of the metal plate is fixedly clamped by the two sets of rotating blocks. The rotating blocks can rotate on the clamping plates. Therefore, the metal plate rotates with the central axis of the rotating block as the rotation axis, and the center of gravity of the metal plate does not shift, avoiding the position movement of the metal plate and being beneficial to improving the stability of the metal plate.

[0010] 2. The utility model hooks the hook on the lifting ring of the metal plate, drives the steel wire rope to move vertically upward through the hydraulic rod, and at the same time drives the steel wire rope to move from right to left through the hydraulic rod.

A fixed rod 3 is installed between the two groups of support rods 2. A lifting block 4 is slidably connected to one of the support rods 2. A guide rod 5 is installed on the lifting block 4. A chute 6 is opened in the guide rod 5. A first lead screw 7 is rotatably installed between the inner walls of the chute 6. A hand wheel 23 is connected to the first lead screw 7. The thread directions on the first lead screw 7 are symmetrically opposite. Two groups of sliders 8 are symmetrically assembled in the chute 6. The sliders 8 are slidably matched with the first lead screw 7 through threads. A clamping plate 9 is installed on the slider 8. A rotating block 10 is rotatably installed on the inner wall of the clamping plate 9. A lifting groove 11 is opened on the support rod 2. A second lead screw 12 is rotatably installed on the inner wall of the lifting groove 11. A first stepping motor 24 is installed on the fixed rod 3 through a machine base. The output shaft of the first stepping motor 24 is connected to the second lead screw 12. The lifting block 4 is assembled in the lifting groove 11. The lifting block 4 is sleeved around the second lead screw 12. The lifting block 4 is slidably matched with the second lead screw 12 through threads. A metal plate 13 is placed on the base 1. A lifting ring 14 is installed on the metal plate 13. A moving groove 15 is opened on the fixed rod 3. A third lead screw 16 is rotatably installed on the inner wall of the moving groove 15. A second stepping motor 17 is installed on the side wall of the fixed rod 3 through a machine base. The output shaft of the second stepping motor 17 is fixedly connected to one end of the third lead screw 16. A moving block 18 is assembled in the moving groove 15. A hydraulic cylinder 19 is installed at the bottom of the moving block 18. A hydraulic rod 20 is connected to the hydraulic cylinder 19. A steel wire rope 21 is connected to the hydraulic rod 20. A hook 22 is connected to the steel wire rope 21. During operation, in the process of turning the metal plate 13 by the existing turning tooling, the steel wire rope 21 is usually used to obliquely pull the metal plate 13 for turning over. However, during the oblique pulling process, the metal plate 13 is prone to center of gravity deviation, resulting in position movement, and the stability of the metal plate 13 is poor. By placing the metal plate 13 under the fixed rod 3, then operating the first stepping motor 24 to drive the second lead screw 12 to rotate, the second lead screw 12 drives the lifting block 4 thereon to move vertically downward. The lifting block 4 drives the guide rod 5 to move vertically downward. The guide rod 5 drives the two groups of clamping plates 9 thereon to move vertically downward, so that the two groups of clamping plates 9 are located at both ends of the metal plate 13. Then rotate the hand wheel 23. The hand wheel 23 drives the first lead screw 7 thereon to rotate. The first lead screw 7 drives the two groups of sliders 8 thereon to move synchronously and relatively. The two groups of sliders 8 drive the two groups of clamping plates 9 to move synchronously and relatively. The two groups of clamping plates 9 drive the two groups of rotating blocks 10 to move synchronously and relatively, so that the two groups of rotating blocks 10 clamp and fix the center of gravity of the metal plate 13;

[0019] Afterwards, hook the hook 22 onto the hanging ring 14 of the metal plate 13. Operate the hydraulic cylinder 19, and the hydraulic rod 20 drives the steel wire rope 21 to move vertically upward. At the same time, operate the second stepping motor 17, the third lead screw 16 rotates, the third lead screw 16 drives the moving block 18 thereon to move horizontally, the moving block 18 drives the hydraulic cylinder 19 to move from right to left, and the hydraulic rod 20 drives the steel wire rope 21 to move from right to left. The steel wire rope 21 obliquely pulls the metal plate 13, causing the metal plate 13 to flip. After the hydraulic rod 20 moves to the left, the hydraulic rod 20 drives the steel wire rope 21 to move vertically downward, and the steel wire rope 21 places the metal plate 13 on the base 1, realizing the turning over of the metal plate 13;

[0020] During the turning-over process, the end of the metal plate 13 with the hanging ring 14 flips, and the other end of the metal plate 13 is fixedly clamped by two groups of rotating blocks 10. The rotating blocks 10 can rotate on the clamping plate 9. Therefore, the metal plate 13 rotates with the central axis of the rotating block 10 as the rotation axis, and the center of gravity of the metal plate 13 does not shift, avoiding the position movement of the metal plate 13 and being beneficial to improving the stability of the metal plate 13.

[0021] Working principle: During the process of turning over the metal plate 13 with the existing turning-over tooling, a steel wire rope 21 is usually used to obliquely pull the metal plate 13 for turning over. However, during the oblique pulling process, the center of gravity of the metal plate 13 is prone to shift, resulting in position movement, and the stability of the metal plate 13 is poor. By placing the metal plate 13 under the fixed rod 3, then operating the first stepping motor 24, the second lead screw 12 is driven to rotate. The second lead screw 12 drives the lifting block 4 thereon to move vertically downward. The lifting block 4 drives the guide rod 5 to move vertically downward. The guide rod 5 drives the two groups of clamping plates 9 thereon to move vertically downward, so that the two groups of clamping plates 9 are located at both ends of the metal plate 13. Then, turn the handwheel 23. The handwheel 23 drives the first lead screw 7 thereon to rotate. The first lead screw 7 drives the two groups of sliders 8 thereon to move synchronously and relatively. The two groups of sliders 8 drive the two groups of clamping plates 9 to move synchronously and relatively. The two groups of clamping plates 9 drive the two groups of rotating blocks 10 to move synchronously and relatively, so that the two groups of rotating blocks 10 clamp and fix the center of gravity of the metal plate 13. Then, hook the hook 22 on the lifting ring 14 of the metal plate 13. By operating the hydraulic cylinder 19, the hydraulic rod 20 drives the steel wire rope 21 to move vertically upward. At the same time, operate the second stepping motor 17, the third lead screw 16 rotates. The third lead screw 16 drives the moving block 18 thereon to move horizontally. The moving block 18 drives the hydraulic cylinder 19 to move from right to left. The hydraulic rod 20 drives the steel wire rope 21 to move from right to left. The steel wire rope 21 obliquely pulls the metal plate 13, so that the metal plate 13 is turned over. Then, after the hydraulic rod 20 moves to the left, the hydraulic rod 20 drives the steel wire rope 21 to move vertically downward. The steel wire rope 21 places the metal plate 13 on the base 1, realizing the turning over of the metal plate 13. During the turning-over process, the end of the metal plate 13 with the lifting ring 14 is turned over, and the other end of the metal plate 13 is fixedly clamped by the two groups of rotating blocks 10. The rotating blocks 10 can rotate on the clamping plates 9. Therefore, the metal plate 13 rotates with the central axis of the rotating blocks 10 as the rotation axis, and the center of gravity of the metal plate 13 does not shift, avoiding the position movement of the metal plate 13 and being beneficial to improving the stability of the metal plate 13.
