Abstract
Description
Technical Field
[0001] This application belongs to the field of ring component processing, specifically relating to a ring compression and necking device. Background Technology
[0002] Ring-shaped workpieces are common components in daily life and mechanical production, and are widely used in many fields, including automotive parts, due to their wide applicability and versatility. For some ring-shaped components with openings, after initial production, the ring-shaped workpieces need to be compressed and narrowed to varying degrees to adjust their inner diameter and adapt to different working conditions. Because ring-shaped workpieces have a certain degree of resilience, during compression and narrowing, uneven force application and difficulty in fixing the ring-shaped workpiece often lead to irregular deformation or the ring-shaped workpiece flying up and down during the narrowing process, affecting the forming efficiency of the ring-shaped workpiece. Utility Model Content
[0003] This application provides a compression ring shrinking device to solve the technical problems of difficult forming and easy dislocation of ring structural parts caused by uneven force application and positioning difficulties when compressing and shrinking ring structural parts in the traditional technology.
[0004] The technical solution adopted in this application is as follows:
[0005] A ring-compression and necking device is used to compress the inner diameter of an annular structural member with an opening. The device includes a base plate, a turntable, and multiple necking blocks. The base plate has a processing area for placing the annular structural member. The processing area has protrusions for upward blocking of the annular structural member, causing the two ends of the opening to be misaligned vertically. The turntable is rotatably mounted on the base plate. The multiple necking blocks are evenly distributed circumferentially around the periphery of the processing area. The turntable is movably connected to the multiple necking blocks. When the turntable rotates relative to the base plate, it can drive the multiple necking blocks to move closer to each other radially along the turntable, thereby compressing the inner diameter of the annular structural member.
[0006] The compression ring narrowing device described in this application also includes the following additional technical features:
[0007] The constricting pressure block is slidably clamped between the base plate and the turntable. The turntable has an arc-shaped groove with a proximal end near the center of the turntable and a distal end away from the center of the turntable. The constricting pressure block has a driving member that slides within the arc-shaped groove. The turntable rotates in a first direction, causing the driving member to slide in the direction from the distal end to the proximal end, thereby causing the multiple constricting pressure blocks to move closer together. The turntable rotates in a second direction, causing the driving member to slide in the direction from the proximal end to the distal end, thereby causing the multiple constricting pressure blocks to move away from each other.
[0008] The constriction block is provided with a guide groove extending radially along the turntable, and the base plate is provided with a guide member. The guide member cooperates in the guide groove to guide the constriction block to move radially along the turntable.
[0009] The base plate has multiple limiting members installed circumferentially on its side. The limiting members abut against the side wall of the turntable to restrict the turntable from moving radially. The limiting members have limiting protrusions that press against the top of the turntable so that the turntable is fixed relative to the base plate axially.
[0010] The turntable has a window opening in the center that runs through both the top and bottom ends, and the processing area is exposed within the window opening.
[0011] The end of the narrowing pressure block near the processing area is provided with a stop part. When the multiple narrowing pressure blocks come close to each other, the stop part stops and limits the ring structure above the ring structure.
[0012] The base plate is provided with multiple limiting blocks, which are evenly distributed around the periphery of the processing area to radially limit the ring structure placed in the processing area. An avoidance channel is formed between two adjacent limiting blocks to avoid the constriction block.
[0013] The processing area is provided with mounting holes, and the mounting holes are provided with elastic elements. The elastic elements can be compressed and hidden in the mounting holes or popped out of the mounting holes, thereby enabling the annular structural members to be popped upward from the processing area.
[0014] The turntable rotates along a first direction to drive the plurality of constricting pressure blocks to move closer to each other. The turntable is provided with a rotating handle, and the base plate is provided with an anti-rotation member. The anti-rotation member is used to stop the rotating handle during the stroke of the turntable rotating along the first direction, thereby limiting the turntable from continuing to rotate along the first direction.
[0015] The base plate is provided with a mounting block, the mounting block is provided with a threaded hole, and the anti-rotation component is provided as a bolt that is screwed into the threaded hole, so that the rotation range of the turntable can be adjusted by changing the screwing depth of the bolt in the threaded hole.
[0016] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:
[0017] 1. The ring-forming and shrinking device of this application includes a base plate with a processing area for supporting the annular structural component. During the shrinking process, the annular structural component is first placed in the processing area, and one end of the ring-forming component with an opening is placed on a protrusion. By rotating a turntable, multiple evenly arranged shrinking blocks are driven to apply a squeezing force to the annular structural component. Under the pressure of the multiple shrinking blocks, the annular structural component deforms and the end point above the protrusion gradually moves inward, thereby reducing the inner diameter of the annular structural component. Throughout the shrinking process, the rotation of the turntable drives the shrinking blocks to move inward. That is, the inward movement amplitude of the shrinking blocks is proportional to the rotation angle of the turntable, and the shrinking degree of the annular structural component is also proportional to the inward movement amplitude of the shrinking blocks. Therefore, the user only needs to control the turntable rotation. The adjustable amplitude allows for precise control of the narrowing amplitude of the annular structural components, which helps improve the consistency of narrowing of each annular structural component under continuous operation conditions. In addition, since the annular structural components are subjected to the extrusion force applied by multiple narrowing pressure blocks during the narrowing process, the stress on the annular structural components is ensured to be uniform, reducing the possibility of stress concentration in some areas of the annular structural components due to uneven stress, and thus reducing the possibility of irregular deformation of the annular structural components due to stress concentration. Furthermore, the setting of the protrusions provides a staggered platform at both ends of the opening of the annular structural components, and on this basis, it provides a guiding role for the subsequent inward narrowing of the annular structural components, so that the part of the annular structural components above the protrusions achieves narrowing along a preset trajectory, which helps to improve the forming stability of the annular structural components.
[0018] 2. In a preferred embodiment of this application, the narrowing pressure block is slidably clamped between the base plate and the turntable, reducing the frictional resistance encountered by the narrowing pressure block during its movement, thereby reducing the rotational force required for the operator to operate the turntable to drive the narrowing pressure block to move; the arc groove design allows the narrowing pressure block to move only along the extension direction of the arc groove, which helps to lock the trajectory of the narrowing pressure block and improves the uniformity of force applied to the annular rotating component by each narrowing pressure block to a certain extent, avoiding the phenomenon of uneven force applied to the annular structural component due to the different movement trajectories of the narrowing pressure blocks; on this basis, the turntable rotates along the first direction to drive the driving component to move from the distal end to the inward end, realizing the inward tightening of the narrowing pressure block, corresponding to the narrowing operation of the annular structural component; when the narrowing operation of the annular structural component is completed, the turntable rotates along the second direction, and the driving component moves from the proximal end to the distal end, driving the narrowing pressure block to return to the initial position, which facilitates the subsequent placement of the annular structural component into the processing area.
[0019] 3. As a preferred embodiment of this application, the guide member on the base plate and the guide groove in the narrowing pressure block cooperate with each other so that the narrowing pressure block can only reciprocate along the extension direction of the guide groove, thereby greatly improving the accuracy of the force applied by each narrowing pressure block to the annular structure, avoiding the occurrence of deviation in the force applied to the annular structure due to the different movement paths between each narrowing pressure block, and greatly improving the narrowing accuracy of the annular structure.
[0020] 4. As a preferred embodiment of this application, by installing a limiting member on the side of the chassis, the radial movement of the turntable can be restricted, preventing radial deviation of the turntable during rotation and affecting the normal movement of the necking block, thus providing stability assurance for the necking operation of the annular structure. On this basis, the setting of the limiting protrusion further restricts the movement of the turntable in the vertical direction, avoiding the occurrence of turntable tilting due to the operator's force deviation when rotating the turntable, and further improving the stability of the necking operation.
[0021] 5. As a preferred embodiment of this application, since the annular structure is continuously compressed during the narrowing process, its internal elastic potential energy continuously accumulates, posing a risk of vertical displacement. By setting a stop, the stop cooperates with the base plate to clamp the annular structure in the vertical direction, avoiding the possibility of vertical displacement of the annular structure during the narrowing process and improving the stability of the narrowing operation.
[0022] 6. As a preferred embodiment of this application, before performing the necking operation, the annular pressure ring needs to be placed in the processing area. The setting of the limiting block is to provide a preliminary limiting function for the annular structure before the necking operation. When the annular structure is placed in the processing area, it cannot move radially or deform due to the abutment of each limiting block. This eliminates the need for operators to fix the annular structure by hand or other means, which helps to improve work efficiency.
[0023] 7. As a preferred embodiment of this application, by providing mounting holes and elastic elements in the processing area, after the shrinking work of a single annular structural component is completed, the extrusion force applied to the annular structural component is removed, and the annular structural component will spring upward under the elastic action of the elastic element. This eliminates the need for the operator to reach into the processing area to pick up the annular structural component, which helps to reduce the working time required for a single annular structural component to complete the entire shrinking work and helps to improve the working efficiency of continuous shrinking operations on annular structural components.

[0044] like Figures 1 to 7 As shown, a ring compression device is used to compress the inner diameter of an annular structural member 6 with an opening. The ring compression device includes a base plate 1, a turntable 2, and multiple compression blocks 3. The base plate 1 is provided with a processing area for placing the annular structural member 6. The processing area is provided with protrusions 11 for upward blocking of the annular structural member 6 so that the two ends of the opening are misaligned vertically. The turntable 2 is rotatably mounted on the base plate 1. The multiple compression blocks 3 are evenly distributed around the periphery of the processing area. The turntable 2 is movably connected to the multiple compression blocks 3. When the turntable 2 rotates relative to the base plate 1, it can drive the multiple compression blocks 3 to move closer to each other along the radial direction of the turntable 2 to compress the inner diameter of the annular structural member 6.
[0045] The ring-forming and shrinking device of this application includes a base plate 1 with a processing area for supporting an annular structural member 6. During the shrinking process, the annular structural member 6 is first placed in the processing area, and one end of the ring-forming member 6 with an opening is placed on a protrusion 11. Rotating the turntable 2 causes multiple evenly arranged shrinking blocks 3 to apply pressure to the annular structural member 6. Under the pressure of the multiple shrinking blocks 3, the annular structural member 6 deforms, causing the end point above the protrusion 11 to gradually move inward, thus reducing the inner diameter of the annular structural member 6. Throughout the shrinking process, rotating the turntable 2 drives the shrinking blocks 3 to move inward; the inward movement amplitude of the shrinking blocks 3 is proportional to the rotation angle of the turntable 2, and the shrinking degree of the annular structural member 6 is also proportional to the inward movement amplitude of the shrinking blocks 3. Therefore, the user only needs to control the turntable. The rotation amplitude allows for precise control of the narrowing amplitude of the annular structural component 6, which helps improve the consistency of narrowing of each annular structural component 6 under continuous operation conditions. In addition, since the annular structural component 6 is subjected to the extrusion force applied by multiple narrowing pressure blocks 3 during the narrowing process, the force on the annular structural component 6 is ensured to be uniform, reducing the possibility of stress concentration in some areas of the annular structural component 6 due to uneven force, and thus reducing the possibility of irregular deformation of the annular structural component 6 due to stress concentration. Furthermore, the setting of the protrusion 11 provides a staggered platform at both ends of the opening of the annular structural component 6, and on this basis, it provides a guiding role for the subsequent inward narrowing of the annular structural component 6, so that the part of the annular structural component 6 above the protrusion 11 narrows along the preset trajectory, which helps to improve the forming stability of the annular structural component 6.
[0046] For ease of explanation, such as Figures 4-7 As shown, the portion of the annular structural member 6 located above the protrusion 11 before the narrowing operation is called the first end point 61, and the end point abutting against the side of the protrusion 11 is called the second end point 62. Figure 4 , Figure 5 In the middle, the annular structural component 6 is in a preparatory state before the narrowing operation, with the first end point 61 and the second end point 62 aligned vertically; in Figure 6 , Figure 7 In the middle, the annular structural component 6 has been narrowed, with the first end point 61 shrinking inward and misaligned with the second end point 62.
[0047] During the narrowing process, the second end point remains stationary under the abutment of the protrusion 11, while the first end point gradually slides inward along the upper surface of the annular structure 6, thus narrowing the annular structure 6.
[0048] As a preferred embodiment of this application, such as Figure 1 , Figure 2As shown, the constricting pressure block 3 is slidably clamped between the base plate 1 and the turntable 2. The turntable 2 is provided with an arc-shaped groove 22, which has a proximal end 21 near the center of the turntable 2 and a distal end 212 away from the center of the turntable 2. The constricting pressure block 3 is provided with a driving member 31 that is slidably engaged in the arc-shaped groove 22. When the turntable 2 rotates in a first direction, the driving member 31 slides in the direction from the distal end 212 to the proximal end 21, thereby driving multiple constricting pressure blocks 3 to move closer to each other. When the turntable 2 rotates in a second direction, the driving member 31 slides in the direction from the proximal end 21 to the distal end 212, thereby driving multiple constricting pressure blocks 3 to move away from each other.
[0049] Specifically, Figure 1 The X direction shown is the first direction of turntable 2, and the Y direction is the second direction of turntable 2.
[0050] The constriction block 3 is slidably clamped between the base plate 1 and the turntable 2, reducing the frictional resistance encountered by the constriction block 3 during its movement, thereby reducing the rotational force required for the operator to move the constriction block 3 by operating the turntable 2. The arc-shaped groove 22 ensures that the constriction block 3 can only move along the extension direction of the arc-shaped groove 22, helping to lock the trajectory of the constriction block 3 and improving the uniformity of force applied by each constriction block 3 to the annular rotating component, thus preventing uneven movement trajectories of the constriction block 3. This leads to uneven force application on the annular structural component. Based on this, the turntable 2 rotates along the first direction, driving the drive component 31 to move from the distal end 212 to the inward end, thereby tightening the narrowing block 3 inward, corresponding to the narrowing operation of the annular structural component. After the narrowing operation of the annular structural component is completed, the turntable 2 rotates along the second direction, and the drive component 31 moves from the proximal end 21 to the distal end 212, driving the narrowing block 3 to return to its initial position, which facilitates the subsequent placement of the annular structural component into the processing area.
[0051] As a preferred embodiment of this implementation, such as Figure 1 , Figure 3 As shown, the narrowing pressure block 3 is provided with a guide groove 32 extending radially along the turntable 2, and the base plate 1 is provided with a guide member 12. The guide member 12 cooperates in the guide groove 32 to guide the narrowing pressure block 3 to move radially along the turntable 2. The guide member 12 on the base plate 1 and the guide groove 32 in the narrowing pressure block 3 cooperate with each other to ensure that the narrowing pressure block 3 can only reciprocate along the extension direction of the guide groove 32, thereby greatly improving the accuracy of the force applied by each narrowing pressure block 3 to the annular structure, avoiding the phenomenon of deviation in the force applied to the annular structure caused by the different movement paths between the narrowing pressure blocks 3, and greatly improving the narrowing accuracy of the annular structure.
[0052] As another preferred embodiment of this implementation, such as Figure 1As shown, multiple limiting members 13 are installed circumferentially on the side of the base plate 1. The limiting members 13 abut against the side wall of the turntable 2 to restrict the radial movement of the turntable 2. The limiting members 13 are provided with limiting protrusions 131 that press against the top of the turntable 2 so that the turntable 2 is fixed relative to the base plate 1 axially. By installing the limiting members 13 on the side of the base plate, the radial movement of the turntable 2 can be restricted, preventing the turntable 2 from radially deviating during rotation and affecting the normal movement of the necking block 3, thus providing stability for the necking operation of the annular structure. On this basis, the setting of the limiting protrusions 131 further restricts the movement of the turntable 2 in the vertical direction, avoiding the tilting of the turntable 2 caused by the operator's deviation in force when rotating the turntable 2, and further improving the stability of the necking operation.
[0053] As another preferred embodiment of this implementation, the turntable 2 has a window opening in the center that runs through both the upper and lower ends, and the processing area is exposed in the window opening.
[0054] The window design provides space for the ring-shaped structural component to be handled, making it easier for staff to operate. On the other hand, the window exposes the ring-shaped structural component to the operator's field of vision, allowing the operator to observe the constriction status of the ring-shaped structural component in real time.
[0055] As a preferred embodiment of this application, such as Figure 1 , Figure 3 As shown, the end of the necking pressure block 3 near the processing area is provided with a stop part 33. When multiple necking pressure blocks 3 approach each other, the stop part 33 stops and limits the ring structure above the ring structure. Since the ring structure is continuously compressed during the necking process, its internal elastic potential energy continues to accumulate, and there is a risk of it breaking free and shifting in the vertical direction. By setting the stop part 33, the stop part 33 cooperates with the base plate 1 to clamp the ring structure in the vertical direction, avoiding the possibility of vertical displacement of the ring structure during the necking process, and improving the stability of the necking operation.
[0056] As a preferred embodiment of this application, such as Figure 1 As shown, the base plate 1 is provided with multiple limiting blocks 14, which are evenly distributed circumferentially around the periphery of the processing area to radially limit the annular structural component placed in the processing area. An avoidance channel 4 is formed between adjacent limiting blocks 14 to avoid the narrowing pressure block 3. Before the narrowing operation, the annular pressure ring needs to be placed in the processing area. The limiting blocks 14 serve as a preliminary limiting mechanism before the narrowing operation. When the annular structural component is placed in the processing area, it cannot move radially or deform due to the abutment of the limiting blocks 14. This eliminates the need for operators to fix the annular structural component by hand, thus improving work efficiency.
[0057] Preferably, the limiting block 14 has a limiting surface facing the processing area, and the limiting surface is arc-shaped. The arc-shaped limiting surface can increase the contact area with the annular structural component and reduce the possibility of stress concentration between the limiting block and the annular structural component.
[0058] As a preferred embodiment of this application, such as Figure 1 As shown, the processing area is provided with mounting holes, and the mounting holes are provided with elastic elements 5. The elastic elements 5 can be compressed and hidden in the mounting holes or popped out of the mounting holes, thereby enabling the annular structural members to be popped upward from the processing area.
[0059] By setting mounting holes and elastic element 5 in the processing area, after the shrinking work of a single ring structure is completed, the extrusion force applied to the ring structure is removed, and the ring structure will bounce upward under the elastic action of the elastic element 5. This eliminates the need for the operator to reach into the processing area to pick up the ring structure, which helps to reduce the working time required for a single ring structure to complete the entire shrinking work and helps to improve the working efficiency of continuous shrinking operations of ring structures.
[0060] Preferably, the elastic element 5 includes a spring located in the mounting hole and a push ball located on top of the spring. During the narrowing operation, the annular structure is subjected to the pressure of the narrowing block 3, and there is a large frictional force between the annular structure and the narrowing block 3. The elastic element 5 cannot pop the annular structure upward. When the narrowing operation is completed, the pressure applied by the narrowing block 3 to the annular structure is removed, and the frictional force is also removed. At this time, the elastic element 5 can pop the annular structure out.
[0061] As a preferred embodiment of this application, such as Figure 1 As shown, the turntable 2 rotates in the first direction to drive multiple constricting pressure blocks 3 to move closer to each other. The turntable 2 is provided with a rotating handle 22, and the base plate 1 is provided with a stop member 15. The stop member 15 is used to stop the rotating handle 22 during the stroke of the turntable 2 rotating in the first direction, thereby limiting the turntable 2 from continuing to rotate in the first direction.
[0062] By setting the rotating handle 22, the operator can manipulate the rotating handle 22 to drive the turntable 2 to rotate, which improves the smoothness of the rotation of the turntable 2; while the setting of the anti-rotation component 15 ensures that the turntable 2 can only rotate at a preset angle, that is, drive the narrowing pressure block 3 to move along a preset length of path, so as to achieve a preset degree of compression of the annular structure, and avoid the narrowing pressure block 3 from squeezing too deeply due to the excessive rotation angle of the turntable 2, which would cause the annular structure to deform and be damaged.
[0063] Preferably, such as Figure 1 As shown, the base plate 1 is provided with a mounting block 16, the mounting block 16 is provided with a threaded hole, and the anti-rotation member 15 is provided as a bolt that is screwed into the threaded hole, so that the rotation range of the turntable 2 can be adjusted by changing the screwing depth of the bolt in the threaded hole.
[0064] This configuration allows for adjustment of the installation position of the anti-rotation component 15, thereby changing the maximum rotation angle of the turntable 2 and achieving different degrees of compression and sizing of the annular structural component. Since the degree of sizing of the annular structural component is directly proportional to the rotation angle of the turntable 2, by adjusting the anti-rotation component 15 to the preset position, the operator only needs to rotate the turntable 2 until it is stopped by the anti-rotation component 15 and can no longer rotate, thus completing the sizing of the annular structural component. The operator does not need to precisely control the rotation angle, which helps improve sizing efficiency.

[0066] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

For those skilled in the art, the present application may have various changes and variations.
