Description

Technical Field

[0001] The invention relates to the field of stainless steel pipe processing, and more specifically to a stainless steel double clamping pipe groove processing device. Background Art

[0002] Stainless steel double clamp pipe fittings are a kind of accessories used for pipe connection, which are widely used in building water supply and drainage, heating, ventilation and air conditioning (HVAC), refrigeration systems, gas transportation and other fields. The characteristics of this type of pipe fittings are that they are designed with special mechanical structures and special tools are used to squeeze the pipe fittings and pipes during installation, so that a tight sealing connection is formed between the pipe fittings and the pipes.

[0003] According to different uses, double clamp pipe fittings can be in various forms such as straight, elbow, tee, cross, etc. to meet the needs of pipeline connection in different directions and angles. The straight double clamp pipe fittings are formed by processing stainless steel pipes. Before the straight double clamp pipe fittings are formed, grooves need to be processed at both ends of the stainless steel pipe.

[0004] For the production of stainless steel pipe fittings with larger diameters, rolling forming is usually used to groove the stainless steel pipe. However, in the past rolling forming process, the roller would apply pressure to a specific position on the inner surface of the stainless steel pipe to form a dent, and then the roller and the stainless steel pipe would continue to rotate to form a complete dent. However, in this case, after the initial dent is formed, continued rotation will need to overcome the friction caused by the deformation and the resistance of the material deformation. The increased friction between the roller and the pipe will cause the roller and the tool to wear faster, thereby increasing production costs. At the same time, the increased resistance will increase the energy consumption of forming, which will not only reduce the efficiency of the entire operation process, but also affect the production speed. Summary of the invention

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide a stainless steel double-clamp pipe groove processing equipment, which makes the applied pressure more uniform by applying pressure while rolling, which helps to facilitate smooth flow during the rolling process and reduce local strain concentration. At the same time, it helps to reduce the stress generated inside the stainless steel pipe and reduce the hardening degree of the material after deformation, thereby reducing the friction and resistance generated.

[0021] (1) This solution extends the output end of the cylinder to push the roller to move slowly upward.

It can effectively avoid the loss caused by friction and the energy consumption caused by resistance, thereby effectively improving work efficiency.

[0022] (2) In this scheme, by setting a wiping block, the wiping block will wipe and clean the surface of the roller and the support ring during the rotation of the roller and the support ring to improve the cleanliness and smoothness of the surface of the roller and the support ring. This can avoid the situation where the residual impurities may cause the roller to easily damage the inner wall of the groove during the processing of the groove of the support ring, and can effectively improve the integrity of the groove, thereby effectively improving the sealing of the subsequent connecting pipe.

[0023] (3) This solution can drive the fan blades to rotate quickly through the cooperation of the large gear and the small gear. The fan blades will blow air into the circular tube. The wind will enter from the bottom of the exhaust port and be discharged from the top of the exhaust port. At this time, the top of the exhaust port will blow air to the raised part of the surface of the stainless steel tube during the groove forming process, which has a cooling effect. It can dissipate the heat generated during the rolling process in time, avoid local overheating of the material and affect the processing effect, and effectively improve the processing effect.

[0033] See also Figures 1 to 6 , a stainless steel double clamp pipe groove processing equipment, comprising a support frame 1, a base 2 is fixedly installed on one side of the support frame 1, and a support plate 3 is fixedly installed on the upper part of the base 2;

[0034] Also includes:

[0035] A rolling assembly includes a rotating rod 4 rotatably mounted on a support plate 3, a roller 5 fixedly mounted on the rotating rod 4, support rings 6 fixedly mounted on both sides of the roller 5, a top seat 7 fixedly mounted on one side of the support frame 1, a rotating rod 8 rotatably mounted in the top seat 7, a guide wheel 9 fixedly mounted on the rotating rod 8, and the guide wheel 9 is located directly above the roller 5, a motor 10 fixedly mounted on one side of the support frame 1, the output end of the motor 10 is fixedly mounted on the rotating rod 8, a cylinder 11 is fixedly mounted between the bottom of the base 2 and the support frame 1, a stainless steel pipe 31 is provided in contact with the top of the roller 5, and a trigger assembly is provided above the support plate 3.

[0036] The trigger assembly includes a top plate 12 disposed above the support plate 3, the top plate 12 is fixedly mounted on the support frame 1, a cylinder 19 is slidably mounted on the top plate 12, contact blocks 20 are fixedly mounted on opposite sides of the cylinder 19 and the support plate 3, two groups of contact blocks 20 are connected in series with the motor 10, and a reset spring 21 is fixedly mounted between the cylinder 19 and the top plate 12;

[0037] A special-shaped rod 13 is rotatably installed on the top plate 12, a fixed rod 14 is slidably installed at the lower part of the special-shaped rod 13, a circular plate 15 is rotatably installed on the top of the fixed rod 14, a telescopic spring 16 is fixedly installed between the circular plate 15 and the top plate 12, bevel gears 18 are fixedly installed on the opposite ends of the special-shaped rod 13 and the fixed rod 14, and bevel gears 2 17 are meshed and installed on the opposite sides of the two sets of bevel gears 18, and the two sets of bevel gears 2 17 are fixedly installed on the rotating rod 8 and the rotating rod 4 respectively.

[0038] Two groups of arc plates 22 are arranged below the stainless steel tube 31. Both groups of arc plates 22 are slidably installed with the base 2. Elastic springs 25 are fixedly installed between the two groups of arc plates 22 and the base 2. A round frame 24 is rotatably installed on the arc plate 22 close to the support plate 3. The round frame 24 is sleeved on one end of the stainless steel tube 31. Balls 23 are evenly rolled and installed on the arc plate 22 away from the support plate 3. Each group of balls 23 is arranged in contact with the stainless steel tube 31.

[0039] First, the staff inserts the stainless steel pipe 31 that needs to be processed with a groove on the outer side of the roller 5, and makes the inner cavity of the stainless steel pipe 31 contact the top of the roller 5, and then pushes the arc plate 22 to move upward. The two sets of arc plates 22 will move synchronously during the up and down movement. The elastic spring 25 will be stretched during the upward movement of the arc plate 22, and the round frame 24 will be moved upward to a suitable position with the stainless steel pipe 31, so as to facilitate the insertion of the stainless steel pipe 31 into the round frame 24. Then, after the stainless steel pipe 31 is inserted into the round frame 24, the thrust applied to the arc plate 22 is cancelled. Under the action of the elastic spring 25, the elastic spring 25 restores the initial state and pulls the round frame 24 downward to the initial position through the arc plate 22. At this time, the arc plate 22 can pull the stainless steel pipe 31 to be close to the top of the roller 5 through the round frame 24, so as to pre-fix the stainless steel pipe 31, and no manual assistance is required in the subsequent processing of the groove, which is more convenient and can effectively reduce manpower.

[0040] When preparing to process the groove, the cylinder 11 is turned on. The output end of the cylinder 11 extends to drive the support plate 3 to move upward through the base 2. The support plate 3 drives the roller 5 through the rotating rod 4 and pushes the stainless steel pipe 31 to move upward. When the support plate 3 moves upward, it will drive the lower contact block 20 to move synchronously. When the top of the stainless steel pipe 31 is about to contact the bottom of the guide wheel 9, the support plate 3 will drive the contact block 20 at its top to contact the contact block 20 at the bottom of the cylinder 19. At this time, the contact of the two groups of contact blocks 20 will control the motor 10 to start, and the output end of the motor 10 will drive the guide wheel 9 to rotate slowly through the rotating rod 8. While the rotating rod 8 rotates, The bevel gear 17 on it is driven to rotate synchronously. The fixed rod 14 and the special-shaped rod 13 are slidably installed. The fixed rod 14 can only slide up and down on the special-shaped rod 13. The upper bevel gear 17 drives the upper bevel gear 18 to rotate. At the same time, the special-shaped rod 13 drives the fixed rod 14 to rotate synchronously. The fixed rod 14 drives the bevel gear 18 at the bottom to rotate synchronously. Through the cooperation of the two sets of bevel gears 17 and the bevel gear 18, the rotating rod 8 can drive the guide wheel 9 to rotate counterclockwise, and the rotating rod 4 can drive the roller 5 and the support ring 6 to rotate in the opposite direction. At this time, the guide wheel 9 and the opposite side of the rotating rod 4 will move to the same When the stainless steel tube 31 is pushed upward and contacts the guide wheel 9, the guide wheel 9 and the roller 5 will jointly drive the stainless steel tube 31 to rotate in one direction. The rotation of the stainless steel tube 31 will drive the round frame 24 to rotate on the adjacent arc plate 22. At the same time, the rotation of the stainless steel tube 31 will roll on each group of balls 23. The setting of each group of balls 23 plays a role in supporting and conveying the stainless steel tube 31. After the stainless steel tube 31 contacts the guide wheel 9, the groove processing work can be carried out. Continue to slowly control the output end of the cylinder 11 to extend and push the roller 5 to move slowly upward. The roller 5 will squeeze the inner cavity wall of the stainless steel tube 31 into the groove on the guide wheel 9. When When the support ring 6 contacts the inner cavity top wall of the stainless steel tube 31, the depth of the final groove can be achieved. This process can realize that the groove of the inner cavity of the stainless steel tube 31 is slowly extruded from shallow to deep. Applying pressure while rolling can make the pressure applied to the material more uniform, which helps the material to flow smoothly during the rolling process, reduces local strain concentration, and helps to reduce the stress generated inside the material and the hardening degree of the material after deformation. It can avoid the situation in which friction and resistance are generated by continuing the rotation processing after the initial formation of the groove in the past, and can effectively avoid the loss caused by friction and energy consumption caused by resistance, thereby effectively improving work efficiency;

[0041] When the rotating rod 4 drives the bevel gear 2 17 thereon to move upward, it will drive the lower bevel gear 18 to move upward synchronously. When the lower bevel gear 18 moves upward, it will drive the fixed rod 14 to slide upward on the special-shaped rod 13. When the fixed rod 14 moves upward, it will drive the circular plate 15 to move upward synchronously and squeeze the telescopic spring 16. In this state, the telescopic spring 16 is in a compressed state, which can make the lower bevel gear 18 tightly meshed with the lower bevel gear 2 17. The rotating rod 4 will not affect the process of driving the lower bevel gear 2 17 to move up and down. At the same time, the rotating rod is rotated by the circular plate 15 and the fixed rod 14. During the rotation of the two sets of bevel gears 18, the telescopic spring 16 will not be affected.

[0042] like Figure 4 and Figure 5 As shown, vertical plates 26 are provided on opposite sides of the two groups of support rings 6, and the two groups of vertical plates 26 are rotatably installed with the rotating rod 4. A wiping block 27 is fixedly installed between the two groups of vertical plates 26. The wiping block 27 is provided in contact with the roller 5 and the two groups of support rings 6. A collecting frame 28 is provided below the wiping block 27, and the collecting frame 28 and the two groups of vertical plates 26 are detachably installed.

[0043] Semicircular blocks 29 are evenly and fixedly installed in the inner cavities of the two groups of support rings 6 . Weighted balls 30 are arranged in the inner cavities of the two groups of support rings 6 . The two groups of weighted balls 30 are arranged in contact with adjacent semicircular blocks 29 .

[0044] Under the gravity of the collecting frame 28 and the lower half of the vertical plate 26, the vertical plate 26 will not move and will always be in a vertical state during the rotation of the roller 5 and the support ring 6 driven by the rotating rod 4. By setting the wiping block 27, the roller 5 and the support ring 6 will be wiped and cleaned by the wiping block 27 during the rotation of the roller 5 and the support ring 6 to improve the cleanliness and smoothness of the surface of the roller 5 and the support ring 6, and avoid the situation that the residual impurities will cause the roller 5 to easily damage the inner wall of the groove during the groove processing of the support ring 6, which can effectively improve the integrity of the groove, thereby effectively improving the sealing of the subsequent connecting pipeline;

[0045] When the rotating rod 4 drives the roller 5 and the support ring 6 to rotate, the support ring 6 will drive the counterweight ball 30 in its inner cavity to roll in its inner cavity. By setting multiple groups of semicircular blocks 29 in the inner cavity of the support ring 6, the counterweight ball 30 can continue to fall to the bottom of the inner cavity of the support ring 6 and collide with the semicircular block 29 in contact with the lowermost side. At this time, the roller 5 can be vibrated, the adhesion of residual impurities on the roller 5 can be reduced, and it is convenient for the wiping block 27 to wipe it off. At the same time, the shock wave will be transmitted to the wiping block 27, and the impurities remaining on the wiping block 27 can be shaken off to the inner cavity of the collecting frame 28, so as to collect the impurities and ensure the cleanliness of the wiping block 27. When it is necessary to clean the collecting frame 28, the collecting frame 28 can be directly disassembled for cleaning.

[0046] like Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, a large gear 32 is provided on the side of the support plate 3 away from the circular frame 24. The large gear 32 is fixedly installed with the rotating rod 4. A small gear 33 is meshed and installed at the bottom of the large gear 32. The small gear 33 is rotatably installed with the support plate 3, and a fan blade 34 is fixedly installed at one end of the small gear 33.

[0047] An exhaust port 35 is provided on one side of the fan blade 34 away from the pinion 33 . The exhaust port 35 is opened on the support frame 1 . The other end of the exhaust port 35 passes through the support frame 1 and the top seat 7 and is placed on the rear side of the guide wheel 9 .

[0048] The outer side of the fan blade 34 is provided with a circular tube for collecting wind. The circular tube is slidably installed with the side wall of the support frame 1 up and down, and is rotatably installed with the rotating shaft on the fan blade 34. The support plate 3 drives the fan blade 34 to move up and down without being affected. When the rotating rod 4 rotates, the rotating rod 4 will drive the large gear 32 thereon to rotate. When the large gear 32 rotates, the small gear 33 will rotate. When the small gear 33 rotates, the fan blade 34 will rotate synchronously. Through the cooperation of the large gear 32 and the small gear 33, the fan blade 34 can be driven to rotate quickly, and the fan blade 34 will blow air into the circular tube, and the wind will enter from the bottom end of the exhaust port 35 and be discharged from the top end of the exhaust port 35. At this time, the top end of the exhaust port 35 will blow air to the convex part of the surface of the stainless steel pipe 31 during the groove forming process, which plays a role in cooling, and can realize the timely dissipation of the heat generated in the rolling process, avoid the situation where the material is locally overheated and affects the processing effect, and can effectively improve the processing effect.

[0049] like Figure 1 and Figure 2 As shown, the distance between the two groups of contact blocks 20 is smaller than the distance between the stainless steel tube 31 and the guide wheel 9 .

[0050] The two groups of arc plates 22 are fixedly installed to facilitate the synchronous movement of the two groups of arc plates 22. The elastic spring 25 is in a stretched state in its initial state.

[0051] The upper half of the special-shaped rod 13 is circular, and the lower half is square.

[0052] The distance between the two groups of contact blocks 20 is smaller than the distance between the stainless steel tube 31 and the guide wheel 9, so that the roller 5 and the guide wheel 9 can be controlled first to drive the stainless steel tube 31 to rotate, thereby facilitating the groove processing by applying pressure while rolling. The upper half of the special-shaped rod 13 is circular and the lower half is square, so that the fixed rod 14 can only slide up and down on the special-shaped rod 13, and the rotation of the special-shaped rod 13 will drive the fixed rod 14 to rotate synchronously, so that the lower side bevel gear 18 can move up and down while the two groups of bevel gears 18 rotate.

[0053] Working principle: First, insert the stainless steel tube 31 into the round frame 24, and fix the stainless steel tube 31 on the top of the roller 5 through the tensile force of the elastic spring 25 to achieve pre-treatment fixation, control the extension of the output end of the cylinder 11 to drive the stainless steel tube 31 to move upward, and before the top of the stainless steel tube 31 contacts the bottom of the guide wheel 9, the two groups of contact blocks 20 will contact and control the motor 10 to start, and the motor 10 will drive the roller 5 and the guide wheel 9 to rotate in opposite directions, and rotate and transport the stainless steel tube 31 in one direction, and continue to control the extension of the output degree of the support frame 1, so as to realize the groove processing of the stainless steel tube 31 by rolling and applying pressure. During the processing, the wiping block 27 will wipe the roller 5 to keep the roller 5 clean and prevent impurities from remaining on the roller 5. The support ring 6 During the rotation process, the cooperation between the counterweight ball 30 and the semicircular block 29 will cause it to vibrate, which can facilitate the impurities wiped on the wiping block 27 to fall into the inner cavity of the collecting frame 28. The collecting frame 28 itself can also be disassembled and cleaned. At the same time, the rotating rod 4 rotates during the processing, and the cooperation between the large gear 32 and the small gear 33 will quickly drive the fan blades 34 to rotate. The fan blades 34 will blow air through the exhaust port 35 to cool the outer surface of the stainless steel pipe 31 after the groove is formed, thereby promoting the dissipation of heat. When the formed stainless steel pipe 31 is removed, the output end of the control cylinder 11 is controlled to contract and drive the stainless steel pipe 31 away from the guide wheel 9, and then the arc plate 22 is pushed to move upward to leave a distance between the stainless steel pipe 31 and the roller 5, so that the stainless steel pipe 31 can be taken out of the round frame 24.

[0054] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
