Description

Technical Field

[0001] This utility model belongs to the field of flange forging technology, specifically a fixing device for flange forging processing. Background Technology

[0002] A flange, also known as a flange plate or flange, is a part used to connect shafts. It is commonly used for connecting pipe ends and is also used at the inlet and outlet of equipment to connect two pieces of equipment, such as a speed reducer flange. Forging refers to the process of applying pressure to a metal billet using forging machinery to cause plastic deformation, thereby obtaining a forging with certain mechanical properties, shape, and size. In the flange forging process, some manufacturers use manual clamps to fix and adjust the flange billet. This manual operation method ensures that the flange has a high degree of flexibility during forging.

[0003] In current technology, when forging flanges, the flange blank must first be heated to a red-hot state before being placed on the processing platform of forging machinery. The machinery is then started, and the hot flange blank is repeatedly hammered. During this process, workers use clamps to constantly adjust the position of the blank. The reason for frequent adjustments is to ensure that all parts of the blank are evenly stressed, allowing the hammering effect to be comprehensive. Through this operation, the internal structure of the flange blank becomes denser and more uniform, thereby improving the overall quality of the flange.

[0004] However, when using clamps to fix flanges, workers need to bear the weight of both the clamps and the blank. Especially when flipping the blank, due to the lack of support points, workers can only rely on their own brute force to adjust the position of the flange blank. This operation method will greatly consume the worker's physical strength, and excessive physical consumption will lead to a decrease in the worker's operating accuracy, which in turn will affect the quality of flange fixing. Therefore, a fixing device for flange forging is proposed to address the above problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Specific implementation examples are given below.

[0026] Please see Figure 1 - Figure 5This utility model provides a fixing device for flange forging, including a forging platform 1; a rotating ring 2 is slidably connected to the top of the forging platform 1; a Z-shaped connecting plate 21 is fixedly connected to the side wall of the rotating ring 2; a fixing shell 22 is fixedly connected to the top of the Z-shaped connecting plate 21; a support rod 23 is slidably connected through the top of the fixing shell 22; a hinge ring 24 is hinged to the top of the support rod 23; a circular ring 27 is slidably connected to the inner wall of the hinge ring 24; a fixing component is provided on the inner wall of the circular ring 27; the fixing component includes a rectangular shell 3; The rectangular shell 3 is slidably connected to the inner wall of the ring 27; a handle 34 is fixedly connected to one end of the rectangular shell 3; a slide rail 31 is fixedly connected to the other end of the rectangular shell 3; a rectangular block 37 is slidably connected to the inner wall of the slide rail 31; a slot 311 is provided at the end of the rectangular block 37; a locking block 310 slides on the inner wall of the slot 311; a clamping plate 32 is fixedly connected to the side wall of the locking block 310; during operation, the flange blank can be placed on the forging platform 1 for processing. During the forging process of the blank, the worker needs to continuously use the fixed... The component adjusts the position of the blank to ensure its processing quality. During adjustment, the rectangular shell 3 slides on the inner wall of the ring 27, allowing for horizontal adjustment of the blank. The ring 27 can slide circumferentially on the inner wall of the hinge ring 24, enabling angle adjustment of the blank. The hinge ring 24 and the support rod 23 are connected by a rotational connection, allowing for rapid flipping of the blank in another direction. Furthermore, the fixing component can simultaneously rotate around the center of the support rod 23 and the center of the rotating ring 2, allowing for multi-angle adjustment of the blank. While ensuring the flexibility of the fixing component, it provides a support point for workers when adjusting the angle of the flange blank, reducing the stress on the fixing component. It also ensures that the angle adjustment of the blank using the fixing component can be achieved through the lever principle, making the operation more labor-saving, improving practicality, and ensuring processing efficiency. In addition, the clamping plate 32 in the fixing component can be disassembled and replaced with the cooperation of the clamping block 310 and the clamping groove 311, ensuring its clamping effect on the blank.

[0027] Furthermore, such as Figure 1 - Figure 2As shown, a movable block 46 is slidably connected to the inner wall of the fixed shell 22; the bottom of the support rod 23 is rotatably connected to the top of the movable block 46; a sliding rod 43 is fixedly connected to the side wall of the movable block 46; a first through groove 26 is opened on the side wall of the fixed shell 22; the sliding rod 43 slides on the inner wall of the first through groove 26; a fixed plate 41 is fixedly connected to the top of the Z-shaped connecting plate 21 on one side of the fixed shell 22; a round rod 45 is fixedly connected through the side wall of the fixed plate 41; a connecting plate 4 is rotatably connected to the outer wall of the round rod 45; a second through groove 44 is opened on the side wall of the connecting plate 4; the outer wall of the sliding rod 43 slides on the inner wall of the second through groove 44; a pressing plate 42 is fixedly connected to the side wall of the connecting plate 4. During operation, in When the height of the blank needs to be adjusted, the operator can step on the pressure plate 42. Stepping on the pressure plate 42 will cause the connecting plate 4 to rotate around the center of the round rod 45. At this time, the other end of the connecting plate 4 will be raised, and the sliding rod 43 will move accordingly and slide on the inner wall of the second through groove 44. At the same time, the sliding rod 43 will drive the moving block 46 to slide on the inner wall of the fixed shell 22. In this way, the support rod 23 and its fixing components will move together, and the blank will be fixed by the fixing components. In this way, the blank can move along with the fixing components, thus adjusting the height of the blank. This facilitates the replacement of the processing mold on the forging platform 1 and improves practicality.

[0028] Furthermore, such as Figure 4 As shown, the inner wall of the slide rail 31 is provided with a slide groove 39; the inner wall of the slide groove 39 is elastically connected to a slider 312 via a spring 38; the slider 312 is slidably connected to the inner wall of the slide groove 39; one end of the spring 38 is fixed to the side wall of the slider 312; the other end of the spring 38 is fixed to the inner wall of the slide groove 39. During operation, when the clamping plate 32 moves, it will simultaneously drive the rectangular block 37 and the slider 312 to move. The slider 312 will slide on the inner wall of the slide groove 39 and squeeze the spring 38. When the rectangular block 37 stops being pulled, the spring 38 will push the slider 312 to move in the opposite direction to reset through its own elasticity. This eliminates the need for workers to pull back and forth to control the opening and closing of the clamping plate 32, improving convenience.

[0029] Furthermore, such as Figure 3 - Figure 4As shown, a handle 33 is fixedly connected to the end of the rectangular block 37 via a steel cable 35; the handle 33 is slidably connected to the inner wall of the rectangular shell 3; one end of the steel cable 35 is fixedly connected to the end of the handle 33; the other end of the steel cable 35 is fixedly connected to the end of the rectangular block 37; a roller 36 is rotatably connected to the inner wall of the slide rail 31; the steel cable 35 slides on the outer wall of the roller 36. During operation, when it is necessary to control the opening and closing of the clamping plate 32, the handle 33 can be pulled to move multiple sets of steel cables 35. The steel cable 35 will drive a set of rectangular blocks 37 to move, and the rectangular blocks 37 will drive the clamping plate 32 to move. This allows control of the opening and closing of the clamping plate 32. In addition, when the steel cable 35 moves, it will drive the roller 36 to rotate, ensuring the smoothness of controlling the opening and closing of the clamping plate 32. Furthermore, when pulling the handle 33, the worker only needs to pull with one hand, while the other hand can hold the handle 34. This allows for alternating work with both hands, which saves energy and improves practicality.

[0030] Furthermore, such as Figure 4 - Figure 5 As shown, the end sidewall of the clamping plate 32 has a threaded hole; the sidewall of the rectangular block 37 is threaded with a bolt 313; the end of the bolt 313 is threaded to the inner wall of the threaded hole. During operation, if the clamping plate 32 is damaged and needs to be replaced, the bolt 313 can be rotated with a tool until the bolt 313 disengages from the inner wall of the threaded hole. At this time, the clamping plate 32 can be pushed to disengage the locking block 310 from the inner wall of the locking groove 311, so that the clamping plate 32 can be replaced. During installation, the locking block 310 is inserted into the inner wall of the locking groove 311, and then the bolt 313 is rotated to insert it into the inner wall of the threaded hole.

[0031] Furthermore, such as Figure 2 As shown, the forging platform 1 has an annular groove 5 at its top. The outer wall of the bottom end of the rotating ring 2 is slidably connected to the inner wall of the annular groove 5. The bottom of the rotating ring 2 is rotatably connected to a rotating block 25, and there are multiple sets of rotating blocks 25. The rotating blocks 25 roll on the inner wall of the annular groove 5. During operation, when the rotating ring 2 is rotated to adjust the angle of the fixed component, the rotating blocks 25 will roll on the inner wall of the annular groove 5 to ensure the smoothness of its rotation.

[0032] Furthermore, such as Figure 3 As shown, the handle 33 is T-shaped; the end of the handle 33 is slidably connected to the side wall of the rectangular shell 3. When working, the horizontal handle of the handle 33 passes through the side wall of the rectangular shell 3, and the operator can use different hands to pull it through its horizontal bar, which improves practicality.

[0033] Working Principle: The flange blank can be placed on the forging platform 1 for processing. During the forging process, the worker needs to continuously adjust the position of the blank using the fixing components to ensure the processing quality. During adjustment, the rectangular shell 3 slides on the inner wall of the ring 27, which can adjust the horizontal direction of the blank. The ring 27 can slide circumferentially on the inner wall of the hinge ring 24, which can adjust the angle of the blank. The hinge ring 24 and the support rod 23 are rotatably connected, which allows the blank to be quickly flipped in another position. In addition, the fixing components can also be used simultaneously... The support rod 23 rotates with the center of the rotating ring 2 as the origin, allowing for multi-angle adjustment of the blank. While ensuring the flexibility of the fixing component, it provides a support point for the worker when adjusting the angle of the flange blank, reducing the worker's stress on the fixing component. It also ensures that the angle adjustment of the blank can be made through the lever principle, making the operation more labor-saving, improving practicality, and ensuring processing efficiency. In addition, the clamping plate 32 in the fixing component can be disassembled and replaced with the cooperation of the clamping block 310 and the clamping groove 311, ensuring its clamping effect on the blank.

[0034] In addition, when the rotating ring 2 is rotated to adjust the angle of the fixed component, the rotating block 25 will roll on the inner wall of the annular groove 5 to ensure smooth rotation.

[0035] When using the fixed components, pulling the handle 33 moves multiple sets of steel cables 35, which in turn move a set of rectangular blocks 37. The rectangular blocks 37 then move the clamping plate 32, thus controlling the opening and closing of the clamping plate 32. Furthermore, the movement of the steel cables 35 drives the rollers 36 to rotate, ensuring smooth control of the clamping plate 32's opening and closing. Additionally, when pulling the handle 33, the worker only needs one hand to pull, while the other hand holds the handle 34, allowing for alternating work and saving energy, thus improving practicality. When the clamping plate 32 moves, it simultaneously moves the rectangular blocks 37 and the slider 312. The slider 312 slides along the inner wall of the groove 39, compressing the spring 38. When pulling the rectangular blocks 37 stops, the spring 38, through its elasticity, pushes the slider 312 in the opposite direction to reset, eliminating the need for the worker to repeatedly pull the clamping plate 32, thus improving convenience.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
