Description

Technical Field

[0001] This utility model relates to the field of forging production technology, specifically to a tooling for placing a transition section of a large-to-small forging. Background Technology

[0002] Forgings refer to workpieces or blanks obtained by forging and deforming metal billets. During the production of the transition section of large and small end forgings, the transition section of the large and small end forgings needs to be placed on a transfer fixture for transfer.

[0003] When the existing transfer fixture transfers the transition section of the large and small end forgings, the large and small end forging transition section is placed on the top placement plate of the transfer fixture, and the transfer fixture is pushed by the workers to transfer the large and small end forging transition section. The large and small end forging transition sections of different lengths are transferred by moving the extension support plate.

[0004] However, in the process of transferring transition sections of forgings of different lengths, the existing transfer tooling requires the operator to adjust the position of the two side extension support plates one by one to adjust the two side extension support plates to the appropriate length before transferring the transition sections of forgings of different lengths. This results in many adjustment steps and long adjustment time when adjusting the extension support plates, thus reducing the effectiveness of the transfer tooling. Utility Model Content

This solves the problem that existing transfer tooling, when transferring transition sections of large and small end forgings of different lengths, results in numerous adjustment steps and long adjustment times when adjusting the extension support plate, thus reducing the effectiveness of the transfer tooling.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tooling for placing a transition section of a large-to-small forging, comprising a base plate, universal wheels mounted on the bottom of the base plate, an empty box fixedly connected to the top of the base plate, a support plate attached to the top of the empty box, a placement seat fixedly connected to the top of the support plate by bolts, a hollow plate fixedly connected to the top of the base plate away from the empty box, a handrail provided on the outside of the hollow plate, and an adjustment device provided inside the empty box, the adjustment device comprising a handwheel, a worm gear, a worm wheel, a slider, a crossbar, a connecting column, and...

The bottoms of the two connecting columns are rotatably connected to columns via third pins. The outer walls of the two columns are slidably engaged with the inner wall of the empty box. A support plate is fixedly connected to the top of the two columns.

[0007] Preferably, a slide rod is slidably engaged with the inner wall of the crossbar, the top of the slide rod is fixedly connected to the inside of the empty box, and the inner wall of the empty box is rotatably connected to the outer wall of the first pin.

[0008] Preferably, a support column is fixedly connected to the bottom of the inner wall of the empty box, and the support column is rotatably connected to the outer wall of the other side of the worm gear through a bearing.

[0012] This utility model provides a fixture for placing the transition section of a large-to-small forging. It has the following advantages: This fixture, through the cooperation of a handwheel, worm gear, worm wheel, slider, horizontal column, connecting column, and vertical column, enables rapid adjustment of the support plate position. This solves the problem that existing transfer fixtures, when transferring large-to-small forging transition sections of different lengths, involve numerous adjustment steps and long adjustment times when adjusting the extended support plate, thus reducing the effectiveness of the transfer fixture.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] The existing transfer tooling, when transferring transition sections of forgings of different lengths, results in numerous adjustment steps and long adjustment times when adjusting the extension support plate, thus reducing the effectiveness of the transfer tooling.

[0022] In view of this, the present invention provides a tooling for placing the transition section of a large-to-small forging. This tooling, through the cooperation of a handwheel, worm gear, worm wheel, slider, horizontal column, connecting column and vertical column, enables rapid adjustment of the position of the support plate. This solves the problem that the existing transfer tooling, when transferring transition sections of large-to-small forgings of different lengths, results in many adjustment steps and long adjustment time when adjusting the extension support plate, thus reducing the effectiveness of the transfer tooling.

[0023] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0024] Example 1, by Figure 1-4As can be seen, the tooling for placing the transition section of the large and small forgings in this case includes a base plate 1. A caster wheel 2 is installed at the bottom of the base plate 1, allowing the base plate 1 to move and transport the transition section. An empty box 3 is fixedly connected to the top of the base plate 1. A support plate 11 is attached to the top of the empty box 3, and a placement seat 13 is fixedly connected to the top of the support plate 11 by bolts. The two large and small forging transition sections are placed into the corresponding placement seats 13. The shape of the placement seat 13 can be changed by rotating the bolts. A hollow plate 14 is fixedly connected to the top of the base plate 1 on the side away from the empty box 3. A handle 21 is provided on the outside of the hollow plate 14. Pushing the handle 21 can rotate the caster wheel 2. An adjustment device is provided inside the empty box 3, including a handwheel 4, a worm gear 5, a worm wheel 6, a slider 7, a horizontal column 8, a connecting column 9, and a vertical column 10. A handwheel 4 is fixedly connected to one end of the worm gear 5, driving the worm gear 5. The worm gear 5 rotates, and one side of its outer wall is rotatably connected to the empty box 3 via a bearing. The outer wall of the worm gear 5 is meshed with a worm wheel 6, which drives the worm wheel 6 to rotate. The inner wall of the worm wheel 6 is fixedly connected to a first pin, which drives the first pin to rotate. The front of the worm wheel 6 is fixedly connected to a slider 7, which drives the slider 7 to rotate. The slider 7 descends, and the outer wall of the slider 7 is slidably engaged with a horizontal column 8. The slider 7 slides in the groove in the middle of the horizontal column 8, thereby driving the horizontal column 8 to move. Both ends of the horizontal column 8 are rotatably connected to connecting columns 9 via second pins, which drive the connecting columns 9 on both sides to rotate. The bottom of both connecting columns 9 is rotatably connected to a column 10 via a third pin, which drives the column 10 to move. The outer walls of both columns 10 are slidably engaged with the inner wall of the empty box 3, and the column 10 on both sides slides in the empty box 3. The top of both columns 10 is fixedly connected to a support plate 11, which drives the support plate 11 to move.

[0025] In the specific implementation process, it is worth noting that the universal wheel 2 is used to move the base plate 1 to transfer the transition section of the large and small end forgings. The large and small end forgings are placed into the corresponding size placement seats 13 in sequence. The operator can change the shape of the placement seat 13 by turning the bolt. The operator can push the handle 21 to make the universal wheel 2 rotate. The handwheel 4 drives the worm gear 5 to rotate. The worm gear 5 drives the worm wheel 6 to rotate. The worm wheel 6 drives the first pin shaft to rotate. The worm wheel 6 drives the slider 7 to rotate. The slider 7 descends and slides in the groove in the middle of the horizontal column 8, thereby driving the horizontal column 8 to move. The horizontal column 8 drives the connecting columns 9 on both sides to rotate. The connecting columns 9 on both sides drive the upright column 10 to move. The upright column 10 on both sides slides in the empty box 3. The upright column 10 on both sides drives the support plate 11 to move, realizing the rapid adjustment of the support plate 11 on both sides.

[0026] Furthermore, a slide rod 12 is slidably engaged with the inner wall of the horizontal column 8. When the horizontal column 8 moves, the horizontal column 8 slides in the slide rod 12. The top of the slide rod 12 is fixedly connected to the inside of the empty box 3, and the inner wall of the empty box 3 is rotatably connected to the outer wall of the first pin.

[0027] In the specific implementation process, it is worth noting that when the horizontal column 8 moves, the horizontal column 8 slides in the slide bar 12, and the slide bar 12 limits the horizontal column 8.

[0028] Furthermore, a support column 22 is fixedly connected to the bottom of the inner wall of the empty box 3. When the worm 5 rotates, the support column 22 supports the right end of the worm 5. The support column 22 is rotatably connected to the other side of the outer wall of the worm 5 through a bearing.

[0029] In the specific implementation process, it is worth noting that when the worm 5 rotates, the support column 22 supports the right end of the worm 5, making the worm 5 more stable when rotating;

[0030] Specifically, when it is necessary to transfer the transition sections of forgings of different lengths, the operator turns the handwheel 4, which drives the worm gear 5 to rotate. The worm gear 5 drives the worm wheel 6 to rotate, which drives the first pin shaft to rotate. The worm wheel 6 drives the slider 7 to rotate, and the slider 7 descends. The slider 7 slides in the groove in the middle of the horizontal column 8, thereby moving the horizontal column 8. The horizontal column 8 drives the connecting columns 9 on both sides to rotate, and the connecting columns 9 on both sides drive the uprights 10 to move. The uprights 10 on both sides slide in the empty box 3, and the uprights 10 on both sides drive the support plates 11 to move. The support plates 11 on both sides drive the placement seats 13 to move. After the positions of the support plates 11 on both sides are adjusted, the operator places the transition sections of the forgings of different lengths into the corresponding placement seats 13. Then, the operator pushes the handle 21 to make the casters 2 rotate, and the casters 2 move the base plate 1 to transfer the transition sections of the forgings of different lengths.

[0031] Example 2, by Figure 3 and 5 It can be seen that a housing 15 is fixedly connected to one inner wall of the hollow plate 14. A moving device is provided inside the housing 15. The moving device includes a rotary knob 16, a threaded rod 17, a threaded block 18, and a vertical plate 19. The bottom of the rotary knob 16 is fixedly connected to the threaded rod 17. The rotary knob 16 drives the threaded rod 17 to rotate. The upper and lower outer walls of the threaded rod 17 are rotatably connected to the housing 15 through bearings. The outer wall of the threaded rod 17 is threadedly connected to the threaded block 18. The threaded rod 17 drives the threaded block 18 to move. A vertical plate 19 is fixedly connected to one side of the threaded block 18. The threaded block 18 drives the vertical plate 19 to move.

[0032] In the specific implementation process, it is worth noting that the rotating knob 16 drives the threaded rod 17 to rotate, the threaded rod 17 drives the threaded block 18 to move, the threaded block 18 drives the vertical plate 19 to move, thereby realizing the movement of the vertical plate 19 and finally realizing the movement of the handrail 21 to adjust the height of the handrail 21.

[0033] Furthermore, the outer wall of the vertical plate 19 is fitted onto the inner wall of the hollow plate 14, the vertical plate 19 slides in the hollow plate 14, and a handrail 21 is fixedly connected to one side of the vertical plate 19, the vertical plate 19 drives the handrail 21 to move.

[0034] In the specific implementation process, it is worth noting that the vertical plate 19 slides in the hollow plate 14, and the vertical plate 19 drives the handrail 21 to move, so as to realize the height adjustment of the handrail 21, which can be adapted to the use of staff of different heights and improve the comfort of staff.

[0035] Furthermore, a sliding post 20 is slidably engaged on the inner wall of the threaded block 18. When the threaded block 18 moves, the threaded block 18 slides on the sliding post 20. Both the upper and lower ends of the sliding post 20 are fixedly connected to the inner wall of the housing 15.

[0036] In the specific implementation process, it is worth noting that when the threaded block 18 moves, the threaded block 18 slides on the slide column 20, and the slide column 20 limits the threaded block 18.

[0037] Specifically, when the height of the handrail 21 needs to be adjusted, the operator rotates the rotary knob 16. The rotary knob 16 drives the threaded rod 17 to rotate, the threaded rod 17 drives the threaded block 18 to move, the threaded block 18 slides on the slide column 20, the slide column 20 limits the threaded block 18, the threaded block 18 drives the vertical plate 19 to move, the vertical plate 19 slides in the hollow plate 14, and the vertical plate 19 drives the handrail 21 to move, thereby adjusting the height of the handrail 21. After the adjustment is completed, the operator stops rotating the rotary knob 16, so that the handrail 21 can be used by operators of different heights.
