Description

Technical Field

[0001] This invention relates to the technical field of stop ring production, and more particularly to a stop ring production apparatus. Background Technology

[0002] Retaining rings are widely used in the mechanical bearing industry. They are annular gaskets with openings and rectangular or square cross-sections. They are used on shafts or threads to prevent loosening and displacement of the shaft or threads. When the shaft or thread is tightened, the inner ring of the retaining ring can be clamped and deformed by compression, thereby generating a force to prevent loosening or displacement and ensuring the stability of the bearing.

[0003] In the production process of the stop ring, the material used is a metal strip with an annular cross-section. The metal strip needs to be extruded into a metal strip with a rectangular cross-section before being plasticized into an annular shape. During the production process, the outer ring of the stop ring may be torn due to the metal strip being extruded into a square shape during the annular extrusion process, which affects the production qualification rate. At the same time, the two extrusion steps are sequential and require the use of two devices in combination. Therefore, a device is proposed that can simultaneously plasticize the metal strip into an annular shape while the metal strip is extruded into a rectangular cross-section. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a stop ring production apparatus to reduce the manufacturing steps of stop rings, improve efficiency and increase the yield rate.

[0005] Based on the technical problems existing in the background art, the present invention proposes a stop ring production device, including a worktable, a first extrusion mechanism, a second extrusion mechanism, and a rotating mechanism for placing metal strips. The rotating mechanism is rotatably mounted on the worktable. The first extrusion mechanism is mounted on the worktable and cooperates with the rotating mechanism to extrude the metal strip into a ring. At the same time, the second extrusion mechanism is slidably mounted on the worktable. The two sides of the metal strip held by the second extrusion mechanism and the rotating mechanism cooperate with the first extrusion mechanism to extrude the metal strip into a stop ring.

[0006] Furthermore, the device also includes a pushing mechanism that is slidably mounted on the worktable and connected to the second extrusion mechanism, and can push the second extrusion mechanism away from the rotating mechanism.

[0007] Furthermore, the first extrusion mechanism includes an arc-shaped frame, a first extrusion member, and a first adjusting member. The arc-shaped frame is mounted on a workbench, and the first extrusion member is rotatably mounted on the arc-shaped frame via the first adjusting member. The first adjusting member is circumferentially distributed on the inner arc side of the arc-shaped frame and adjusts the distance between the first extrusion member and the rotating mechanism to extrude the metal strip into a ring.

[0008] Furthermore, the rotation axis of the first extruder on the first adjusting member is parallel to the rotation axis of the rotating mechanism on the worktable.

[0009] Furthermore, the second extrusion mechanism includes a ring frame, a second extruder, and a second adjusting member. The ring frame is slidably mounted on the worktable along the rotation axis of the rotating mechanism. The second extruder is rotatably mounted on the ring frame via the second adjusting member. The second adjusting member is circumferentially distributed on the ring frame and can adjust the distance between the second extruder and the plane of the rotating mechanism.

[0010] Furthermore, the ring frame has a discharge area and a compression area, and the second adjusting member is installed in the compression area of ​​the ring frame, and the area of ​​the discharge area is greater than half of the ring frame.

[0011] Furthermore, a top post is also installed on the ring frame, which can push the stop ring out from the rotating mechanism as the ring frame moves.

[0012] Compared with the prior art, the stop ring production device proposed in this invention adopts the above-mentioned technical solution and achieves the following technical effects:

[0013] This invention can compress the metal strip during the process of forming a ring, so that the cross-section of the metal strip is rectangular, thereby reducing the steps of making the metal strip into a stop ring;

[0014] In this invention, the metal strip is compressed when forming a ring, which can reduce the risk of the outer ring tearing during the formation of the stop ring, and also reduce the risk of the inner ring of the metal ring being compressed and piled up, thereby increasing the rigidity of the metal ring;

[0015] In this invention, the metal strip can be compressed during the ring-forming process, reducing the number of manufacturing steps and improving the efficiency of manufacturing the stop ring. Attached Figure Description

[0024] Example

[0025] Reference Figures 1-5This invention proposes a stop ring production device, including a workbench 1, on which a support 11 is vertically mounted. The support 11 is connected to the workbench 1 as a whole or can be detachably installed. The device also includes a first extrusion mechanism 2, a second extrusion mechanism 3, and a rotating mechanism 4 for placing metal strips. The rotating mechanism 4 is rotatably mounted on the support 11 and can rotate freely on the support 11. The first extrusion mechanism 2 and the rotating mechanism 4 are mounted on the same side. In this invention, the rotating mechanism 4 is a rotating roller with an L-shaped annular groove 41 on its cross-section. The first extrusion mechanism 2 is close to the outer ring of the rotating roller and can extrude the metal strip entering the annular groove 41. The first extrusion mechanism 2 is mounted on the workbench 1 and cooperates with the rotating mechanism. 4. The metal strip is extruded to form a ring. While the first extrusion mechanism 2 is working with the rotating roller to form the metal strip into a ring, it also extrudes the inner and outer rings of the metal strip, so that the outer and inner rings on the cross-section of the metal strip are in a straight state. At the same time, the second extrusion mechanism 3 is slidably installed on the worktable 1. The second extrusion mechanism 3 is also on the same side of the support 11 as the rotating roller. The second extrusion mechanism 3 can form a transverse clamping and extrusion with the rotating roller. The initial cross-section of the metal strip is circular. When passing through this device, the cross-section of the metal strip is also extruded into a rectangle during the process of forming the ring. The two sides of the metal strip held by the second extrusion mechanism 3 and the rotating mechanism 4 cooperate with the first extrusion mechanism 2 to extrude the metal strip into a stop ring.

[0026] In a specific embodiment, refer to Figure 1 , Figure 2 , Figure 5 The device also includes a pushing mechanism 5, which is slidably mounted on the worktable 1 and connected to the second extrusion mechanism 3, and can push the second extrusion mechanism 3 away from the rotating mechanism 4. The pushing mechanism 5 is mounted on the side of the bracket 11 away from the rotating roller. The pushing mechanism 5 can be a cylinder or a hydraulic mechanism. The pushing mechanism 5 can push the second extrusion mechanism 3 away from the rotating roller, providing space for the finished stop ring to disengage and be easily removed.

[0027] In a specific embodiment, refer to Figure 1 , Figure 3The first extrusion mechanism 2 includes an arc-shaped frame 21, a first extrusion member 22, and a first adjusting member 23. The arc-shaped frame 21 is mounted on a bracket 11 on the worktable 1, and the arc-shaped frame 21 and the rotating roller are on the same side. The inner arc diameter of the arc-shaped frame 21 is larger than that of the rotating roller. The first extrusion member 22 is rotatably mounted on the arc-shaped frame 21 through the first adjusting member 23. The first adjusting member 23 is circumferentially distributed on the inner arc side of the arc-shaped frame 21 and adjusts the distance between the first extrusion member 22 and the rotating mechanism 4 to extrude a metal strip to form a ring. The first adjusting member 23 can be a hydraulic mechanism or a spring mechanism. In this invention, the first adjusting member 23 includes a first sliding rod 231 and a first elastic member 232. The first sliding rod 231 can slide radially along the rotating roller. The first sliding rod 231 is located on the inner arc side of the arc-shaped frame 21. The first elastic member 232 is installed between the first sliding rod 231 and the arc-shaped frame 21. The first elastic member 232 is always in a compressed state and can push the first extrusion member 22 to move towards the rotating roller.

[0028] In a specific embodiment, refer to Figure 1 , Figure 3 The rotation axis of the first extruder 22 on the first adjusting member 23 is parallel to the rotation axis of the rotating mechanism 4 on the worktable 1. In this invention, the first extruder 22 is a roller, and its rotation axis is the same as that of the rotating roller.

[0029] In a specific embodiment, refer to Figure 1 , Figure 4 , Figure 5 The second extrusion mechanism 3 includes a ring frame 31, a second extruder 32, and a second adjusting member 33. The ring frame 31 is slidably mounted on the worktable 1 along the rotation axis of the rotating mechanism 4. The ring frame 31 can be close to or away from the support 11. The second extruder 32 is rotatably mounted on the ring frame 31 through the second adjusting member 33. The second adjusting member 33 includes a second slide rod 331, which is horizontally slidably mounted on the ring frame 31. A second elastic member 332 is installed between the second slide rod 331 and the ring frame 31. The second elastic member 332 can push the second extruder 32 to move toward the rotating roller. In this invention, the second extruder 32 is a roller, and the rotation axis of the second extruder 32 is radial to the rotating roller. The second adjusting member 33 is circumferentially distributed on the ring frame 31 and can adjust the distance between the second extruder 32 and the plane of the rotating mechanism 4.

[0030] In a specific embodiment, refer to Figure 1 , Figure 4 The ring frame 31 has a discharge area and a compression area. The second adjusting member 33 is installed in the compression area of ​​the ring frame 31, and the area of ​​the discharge area is greater than half of the ring frame 31. Half of the space on the ring frame 31 needs to be reserved for the stop ring to detach and fall off. Therefore, at least half of the continuous area of ​​the ring frame 31 must be free of space for the second adjusting member 33 to be installed.

[0031] In a specific embodiment, refer to Figure 1 , Figure 4 , Figure 5 The ring frame 31 is also equipped with a top column 311, which can push the stop ring out from the rotating mechanism 4 as the ring frame 31 moves.
