At this time, the second rack will mesh with one of the second protrusion sections to drive the damping sleeve to rotate the rotating disc in the same direction as before. In the case of saving the power source, the rotating disc can be driven to rotate in the same direction and at the same angle during each reciprocating movement of the stamping seat.

DETAILED DESCRIPTION

[0043] The following will be described in detail with reference to the accompanying drawings. Figures 1-8 The present application will be further described in detail.

[0044] The embodiment of the present application discloses a compression ring. Referring to Figure 1 and Figure 2 The compression ring comprises a mounting cylinder 1 and a compression ring 11. The compression ring 11 is located at one end of the mounting cylinder 1, and the mounting cylinder 1 and the compression ring 11 are integrally formed by stamping technology. Among them, the mounting cylinder 1 and the compression ring 11 can be stainless steel material, or aluminum material, copper material or iron material.

[0045] Referring to Figure 1 and Figure 2The inner diameter of the compression ring 11 is smaller than the inner diameter of the mounting cylinder 1, and the thickness of the compression ring 11 is smaller than the thickness of the mounting cylinder 1. An inclined chamfer 12 is arranged on the outer edge of the end of the mounting cylinder 1 away from the compression ring 11, an outer wall thread 13 is arranged on the outer peripheral wall of the mounting cylinder 1, and a notch 14 is arranged on the compression ring 11. Preferably, four notches 14 are arranged on the compression ring 11 and are evenly distributed in the circumferential direction. When it is necessary to tighten or loosen the compression ring, a tool can be inserted into two notches 14 to rotate the compression ring.

[0046] The implementation principle of the compression ring in the embodiment of the application is as follows: the mounting cylinder 1 and the compression ring 11 are integrally formed by stamping during production and processing, compared with the processing method of welding the two together and then polishing. The above only needs to stamp the tubular blank to process the compression ring, and the processing is more convenient. Due to the stamping process, the thickness of the compression ring 11 is smaller than the thickness of the mounting cylinder 1. The arrangement of the inclined chamfer 12 prevents the edge of the mounting cylinder 1 from scratching the worker.

[0047] The embodiment of the application also discloses a compression ring processing technology, mainly using a cutting machine, a stamping device, a lathe and a polisher. The processing technology comprises the following steps.

[0048] 1. Cutting a whole circular pipe into a plurality of tubular compression ring blanks by a cutting machine;

[0049] 2. Forming the compression ring 11 by a stamping device;

[0050] 3. Turning the compression ring by a lathe;

[0051] 3.1. Turning the inclined chamfer 12 by the lathe;

[0052] 3.2. Turning the outer wall thread 13 by the lathe;

[0053] 3.3. Turning the four notches 14 by the lathe;

[0054] 4. Polishing the compression ring by a polisher;

[0055] 4.1. Polishing the outer surface of the compression ring by the polisher;

[0056] 4.2. Polishing the groove wall of the notch 14 by the polisher.

[0057] The embodiment of the application also discloses a compression ring processing device. Referring to Figure 3 and Figure 4The pressing ring processing device comprises a base 2, a rotating disc 21, a clamp assembly 3, a punching mechanism 4 and a linkage mechanism 5. The rotating disc 21 is rotatably installed on the base 2, and the clamp assembly 3 is installed on the rotating disc 21 to clamp the pressing ring and rotate synchronously with the rotating disc 21. The punching mechanism 4 is slidably installed on the base 2 in the vertical direction to punch the pipe into the pressing ring. When the punching mechanism 4 reciprocally slides, the rotating disc 21 will rotate in the same direction at intervals under the action of the linkage assembly, thereby driving the blank of the pressing ring to rotate.

[0058] With reference to Figure 3 With Figure 4 The clamp assembly 3 is provided with a plurality of clamp assemblies 3, which are evenly and spacedly arranged on the rotating disc 21. Six clamp assemblies 3 are preferably arranged in the embodiment, and the six clamp assemblies 3 are the same in structure. When the punching mechanism 4 slides upward, the tubular pressing ring blank is punched to close the end portion. When the punching mechanism 4 slides downward, the tubular blank after closing is punched, and the pressing ring piece 11 is formed.

[0059] The damping sleeve 22 is fixedly installed on one side of the rotating disc 21 in the axial direction. The base 2 comprises a bottom plate 23, a vertical plate 24 and a fixed shaft 25. The vertical plate 24 is fixedly installed on the top of the bottom plate 23, and the fixed shaft 25 is fixedly installed on the vertical plate 24. The rotating disc 21 and the damping sleeve 22 are sleeved on the fixed shaft 25 and can rotate around the fixed shaft 25 as the rotating shaft. The damping sleeve 22 and the fixed shaft 25 have a certain damping force, so that the rotating disc 21 is not easy to rotate under the action of gravity when the damping sleeve 22 is not forced.

[0060] With reference to Figure 4 With Figure 5 The clamp assembly 3 is installed on the side of the rotating disc 21 away from the vertical plate 24. The clamp assembly 3 comprises a mounting plate 31 fixedly installed on the rotating disc 21, a clamping cylinder 32 fixedly installed on the mounting plate 31 and two clamping half-rings 33 installed on the clamping cylinder 32 to clamp or release the pressing ring. Since the clamping part of the clamping cylinder 32 is two clamping jaws approaching or moving away from each other, the two clamping half-rings 33 are respectively installed on the two clamping jaws, and the two clamping half-rings 33 are oppositely arranged along the sliding direction of the clamping jaws. The two clamping half-rings 33 can tightly clamp the mounting cylinder 1.

[0061] With reference to Figure 5 With Figure 6, the stamping mechanism 4 includes a stamping seat 41, an upper stamping die 42, a lower stamping die 43 and a stamping hydraulic cylinder 44. The upper stamping die 42 is fixedly installed on the top of the stamping seat 41 for stamping the tubular blank material rotating to the top of the stamping to make the end of the tubular blank material close to the upper stamping die 42 into a closed state. The lower stamping die 43 is fixedly installed on the bottom of the stamping seat 41 for stamping the tubular blank material processed by the upper stamping die 42 to form the compression ring piece 11. The end of the fixed shaft 25 away from the vertical plate 24 is fixedly installed with a connecting block 26, the stamping seat 41 is slidingly installed on the connecting block 26, and the stamping hydraulic cylinder 44 is also installed on the connecting block 26 for driving the stamping seat 41 to slide.

[0062] Referring to Figure 6 With Figure 7 , the connecting block 26 is fixedly installed with a dovetail bar 261, and the stamping seat 41 is provided with a dovetail groove 411 for inserting the dovetail bar 261, the dovetail groove 411 penetrates the stamping seat 41 along the vertical direction. The stamping seat 41 can slide on the connecting block 26 through the cooperation of the dovetail bar 261 and the dovetail groove 411. The cylinder body of the stamping hydraulic cylinder 44 is fixedly installed on the connecting block 26, and the telescopic rod of the stamping hydraulic cylinder 44 is connected to the stamping seat 41, so that the stamping hydraulic cylinder 44 can drive the stamping seat 41 to move up and down along the vertical direction.

[0063] Referring to Figure 4 With Figure 6 , the side of the vertical plate 24 where the fixed shaft 25 is installed is provided with a top supporting assembly 6 cooperating with the upper stamping die 42 to limit the compression ring from being clamped and abutted. The top supporting assembly 6 includes a top plate 61, a top hydraulic cylinder 62 and a top die seat 63. The top plate 61 is fixedly installed on the vertical plate 24, the cylinder body of the top hydraulic cylinder 62 is fixedly installed on the top of the top plate 61, and the telescopic rod of the top hydraulic cylinder 62 penetrates the top plate 61 and is located on the bottom of the top plate 61. The top die seat 63 is installed on the telescopic rod of the top hydraulic cylinder 62. When the blank to be processed is rotated to the position between the top die seat 63 and the upper stamping die 42, the stamping seat 41 moves upward, at the same time, the top hydraulic cylinder 62 drives the top die seat 63 to move towards the stamping seat 41, thereby clamping and stamping the blank, so that the end of the blank close to the upper stamping die 42 is in a closed state. When the stamping seat 41 moves downward, the top hydraulic cylinder 62 drives the top die seat 63 to move away from the stamping seat 41, so that the top die seat 63 does not interfere with the rotation of the rotating disc 21.

[0064] Referring to Figure 4 With Figure 6A bottom support assembly 7, which cooperates with the lower stamping die 43 to support the clamping ring, is installed on the base plate 23. The bottom support assembly 7 includes a bottom hydraulic cylinder 71 and a bottom die base 72. The cylinder body of the bottom hydraulic cylinder 71 is fixedly installed on the bottom of the base plate 23, and the telescopic rod of the bottom hydraulic cylinder 71 passes through the base plate 23 and is located above the base plate 23. The bottom die base 72 is installed on the telescopic rod of the bottom hydraulic cylinder 71. When the stamping seat 41 moves downward, the bottom hydraulic cylinder 71 drives the bottom die base 72 to move closer to the stamping seat 41, thereby clamping and stamping the blank, and stamping out the clamping ring 11. When the stamping seat 41 moves upward, the bottom hydraulic cylinder 71 drives the bottom die base 72 to move away from the stamping seat 41, so that the bottom die base 72 does not interfere with the rotation of the turntable 21.

[0065] Reference Figure 6 and Figure 8 The linkage mechanism 5 includes a first linkage component 51 and a second linkage component 52, both of which are connected to the stamping base 41. The second linkage component 52 and the first linkage component 51 are arranged opposite to each other and spaced apart along the axial direction of the damping sleeve 22. When the stamping base 41 moves downward, the first linkage component 51 drives the turntable 21 to rotate counterclockwise, at which time the second linkage component 52 does not interfere with the turntable 21. When the stamping base 41 moves upward, the second linkage component 52 drives the turntable 21 to rotate counterclockwise again, at which time the first linkage component 51 does not interfere with the turntable 21.

The first convex block 514 is located on one side of the first convex tooth segment 513 and is installed on the damping sleeve 22 for driving the first rack 512 to move away from the damping sleeve 22 after being extruded, so that the first rack 512 is not engaged with the first convex tooth segment 513. The number of the first convex block 514 is consistent with and corresponds to the number of the first convex tooth segment 513.

[0067] With reference to Figure 6 With reference to Figure 8The second linkage assembly 52 comprises a second linkage plate 521, a second rack 522, a second protruding tooth segment 523, a second protruding block 524, a second abutting plate 525 and a second spring 526.
