Description

Technical Field

[0001] The present invention relates to the technical field of electrofusion pipe processing, and more particularly to a clamping device for electrofusion pipe processing. Background Art

[0002] Electric fusion pipe fittings are polyethylene pipe fittings that can be melted by the temperature generated by electric current to achieve connection. In the application of polyethylene pipe systems, electric fusion pipe fittings play an important role, especially in engineering and maintenance. They are less affected by the external environment and human factors, so they are more reliable and more popular with users. The main material of electric fusion pipe fittings is copper wire, which is connected by heating it to the required temperature through electric current. This connection method reduces the production cost. At the same time, electric fusion pipe fittings have the advantages of high resistance, non-toxicity, and high corrosion resistance to chemicals. Therefore, their safety and service life are guaranteed. When processing electric fusion pipe fittings, a clamping device is required to fix the mold of the electric fusion pipe fittings.

[0003] The clamping device of the electric fusion pipe fitting includes a motor, a clamping table, a clamping piece and an adjusting screw. When the electric fusion pipe fitting needs to be processed, the mold of the electric fusion pipe fitting can be placed on the clamping table, and the clamping piece can be moved by rotating the adjusting screw so that the clamping piece can fix the mold of the electric fusion pipe fitting on the clamping table. Then the mold will be driven by the motor to rotate to wind the wire at the designated position. After the wire winding is completed, the mold can be lowered from the clamping table, and the molten plastic can be laid on the outside of the mold through the injection molding machine, and the wire can be embedded in the plastic. After the molded plastic pipe fitting is cooled, the molded pipe fitting can be demolded.

[0004] In the prior art, when processing elbow-type electric fusion pipe fittings, since the mold of the elbow-type pipe fittings can only perform winding processing on one end during the winding processing, the mold needs to be flipped after the winding processing on one end of the mold, so that the other end of the mold can be flipped toward the bottom, and the other end of the mold is fixed by a clamping table, and the clamping table is driven to rotate by a motor to allow the mold to be wound.

[0031] In order to solve the problem that the mold is not convenient to flip during the processing of elbow-type electric fusion pipe fittings, when it is necessary to process the elbow-type electric fusion pipe fittings, one end of the elbow mold can be placed on the top of the clamping table 4, and the positions of the two sets of clamps 5 can be adjusted by adjusting the adjustment screw in the clamping table 4, so that the position of the elbow mold can be fixed at the top of the clamping table 4, and then one end of the wire can be fixed on the elbow mold, and then the first motor 3 can be started, and the rotating component at the top and the clamping table 4 can be driven to rotate together by the first motor 3. When the clamping table 4 rotates, the wire can be continuously wound around the elbow mold, and by setting the rotating component, the clamping table 4 can be gradually pushed to move upward while the elbow mold on the clamping table 4 rotates, so that the elbow can be While the wire is wrapped around the surface of the mold, the elbow mold is gradually pushed upward, so that the wire can be evenly laid on the surface of the elbow mold. By setting a flipping component, when the elbow mold needs to be flipped, the elbow mold can be flipped by the flipping component, so that the end of the elbow mold that is not wrapped with the wire is rotated to the top of the clamping table 4, thereby improving the efficiency of the elbow mold winding. By setting a wire feed component, when the surface of the elbow mold is wound, it is convenient to transfer the wire to one side of the elbow mold in time. By setting a pause component, the wire transmission to one side of the elbow mold can be stopped when the elbow mold does not need to be wound.

[0032] Reference Figure 1-4The rotating assembly includes a cylinder 7, which is fixedly connected to the output end of the first motor 3. Side grooves 8 are provided on both sides of the inner wall of the cylinder 7. A round rod 9 is inserted into the inner wall of the cylinder 7. Side blocks 10 are fixedly connected to both sides of the round rod 9. Two groups of side blocks 10 are inserted into the inner walls of the two groups of side grooves 8. A threaded sleeve 11 is fixedly connected to the top of the round rod 9. The inner wall of the threaded sleeve 11 is sleeved on the top of the cylinder 7. The top of the threaded sleeve 11 is fixedly connected to the bottom of the clamping table 4. A sleeve plate 12 is fixedly connected to the top of the processing table 1. The sleeve plate 12 is cylindrical in shape. A square hole is provided on one side of the sleeve plate 12. The sleeve plate 12 is sleeved on the outer wall of the threaded sleeve 11. A vertical plate 13 is fixedly connected to the top of the processing table 1. A side rod 14 is fixedly connected to one side of the vertical plate 13. The end of the side rod 14 away from the vertical plate 13 is inserted into the threaded groove of the outer wall of the threaded sleeve 11.

[0033] When the elbow mold needs to be wound, the first motor 3 can be started, and the top cylinder 7 can be driven to rotate by the first motor 3. When the cylinder 7 rotates, since the side blocks 10 on both sides of the round rod 9 are inserted into the side grooves 8 on the inner wall of the cylinder 7, the round rod 9 will be driven to rotate. At the same time, the round rod 9 will drive the top threaded sleeve 11 and the clamping table 4 to rotate together. Since the top of the processing table 1 is provided with a vertical plate 13 and a side rod 14, and the side rod 14 slides in the thread groove on the outer wall of the threaded sleeve 11, when the thread groove rotates, the position of the side rod 14 on the inner wall of the threaded sleeve 11 will be adjusted, so that the threaded sleeve 11 gradually moves upward during rotation, so that the position of the top clamping table 4 and the elbow mold can be gradually raised, so that the wire can be gradually wrapped around the outer wall of the elbow mold from top to bottom, and by providing the sleeve plate 12, a protective effect can be provided for the outer wall of the threaded sleeve 11.

[0034] Reference Figure 5-7The flip assembly includes a support table 15, which is fixedly connected to the output end of the first hydraulic cylinder 6. The bottom of the support table 15 is slidably arranged on the top of the processing table 1. The top of the support table 15 is fixedly connected to a mounting plate 16, and a second motor 17 is fixedly connected to one side of the mounting plate 16. A threaded rod 18 is fixedly connected to the output end of the second motor 17. A fixing groove 19 connected to the thread groove is provided at one end of the threaded rod 18 away from the second motor 17. A straight groove 20 connected to the thread groove is provided at the other end of the threaded rod 18. A collar 21 is slidably arranged on the outer wall of the threaded rod 18. A circular protrusion is fixedly connected to the inner wall of the collar 21. The circular protrusion is slidably connected to the thread groove of the outer wall of the threaded rod 18. A clamping block 22 is fixedly connected to one side of the collar 21, and a guide plate 23 is fixedly connected to the bottom of the collar 21. A slide groove is provided at the top of the support platform 15, and the bottom of the guide plate 23 is slidably connected to the inner wall of the slide groove. A top plate 24 is fixedly connected to the top of one side of the support platform 15, and a first opening 25 is provided on one side of the top of the top plate 24. The inner wall of the first opening 25 is rotatably connected to a baffle through a rotating shaft, and a first spring is fixedly connected to the bottom of the baffle. One end of the first spring away from the baffle is fixedly connected to the inner wall of the top plate 24, and a second opening 26 is provided on the other side of the top of the top plate 24. A third opening 27 is provided on one side of the support platform 15, and a fourth opening 28 is provided on the other side of the support platform 15. The third opening 27 and the fourth opening 28 are both connected to the slide groove, and a groove is provided at the bottom of the fourth opening 28. A second spring is fixedly connected to the inner wall of the groove, and an inclined block 29 is fixedly connected to the top of the second spring.

[0035] When the elbow mold needs to be turned over, the clamping piece 5 on the clamping table 4 can be first released from the fixation of the elbow mold, and then the support table 15 is pushed to one side by the first hydraulic cylinder 6, and the support table 15 is pushed to one side of the elbow mold, and then the second motor 17 can be started to Figure 5From a perspective, the threaded rod 18 is driven by the second motor 17 to rotate counterclockwise. When the threaded rod 18 rotates, the collar 21 on its outer wall can slide in the thread groove on the outer wall of the threaded rod 18 through the circular protrusion, so that the collar 21, the clamping block 22 and the guide plate 23 can be moved to one side of the elbow mold. At this time, the bottom of the guide plate 23 slides in the slide groove at the top of the support platform 15, and when the clamping block 22 moves to the outer wall of the elbow mold, the circular protrusion on the inner wall of the collar 21 will slide into the fixed groove 19 at the end of the thread groove, and the position of the bottom of the guide plate 23 will also move to the third opening 27, so that when the threaded rod 18 rotates counterclockwise, the collar 21, the guide plate 23 and the clamping block 22 can move along with the thread groove. The rod 18 rotates counterclockwise together, so that the elbow mold clamped by the clamping block 22 can rotate counterclockwise. When the elbow mold rotates counterclockwise to 270 degrees, the end of the elbow mold that is not wound will rotate to the top of the clamping table 4, and the guide plate 23 will also be rotated into the first opening 25. The guide plate 23 rotates downward to squeeze the baffle in the first opening 25, and the baffle squeezes the first spring downward through the rotating shaft until the bottom of the guide plate 23 is rotated to the inner wall of the top plate 24, and the first spring will push the baffle to reset, so that the position of the first opening 25 can be blocked, and then the second motor 17 can be rotated in the opposite direction to make the second motor 17 drive the threaded rod 18 to rotate clockwise, and the threaded rod 18 rotates clockwise. When rotating, the circular protrusion in the collar 21 will be disengaged from the fixed groove 19, so that the collar 21 can slide in the thread groove of the outer wall of the threaded rod 18 through the circular protrusion, so that the collar 21, the clamping block 22 and the guide plate 23 move horizontally to the side away from the elbow mold, so that the clamping block 22 is removed from the outer wall of the elbow mold, and when the circular protrusion in the collar 21 rotates to the end of the thread groove of the outer wall of the threaded rod 18, the circular protrusion will slide into the inner wall of the straight groove 20, so that the collar 21, the clamping block 22 and the guide plate 23 can be driven to rotate clockwise together through the clockwise rotation of the threaded rod 18, and the position of the end of the guide plate 23 is set at the bottom of the second opening 26, so that the guide plate 23 can be rotated clockwise and brought out of the top plate 24, and after rotating 270 degrees clockwise, the end of the guide plate 23 is rotated into the fourth opening 28, and the thrust generated by the rotation pushes the inclined block 29 downward, squeezing the second spring until the end of the guide plate 23 rotates into the slide groove at the top of the support platform 15, so that the positions of the clamping block 22, the collar 21 and the guide plate 23 can be reset, and the slide groove is provided with an inclined surface, which will slightly push the position of the guide plate 23 to the side away from the second motor 17, thereby driving the collar 21 at the top of the guide plate 23 to move together, so that the circular protrusion on the inner wall of the collar 21 is pushed back from the straight groove 20 into the threaded groove, which is convenient for the next work, and then the support platform 15 can be moved to one side by the first hydraulic cylinder 6.

[0036] Reference Figure 8-10The inlet assembly includes a first gear 30, which is fixed to the outer wall of the cylinder 7, and a gear ring 31 is meshed on one side of the first gear 30. A support block is fixed to the bottom of the processing table 1, and the gear ring 31 is slidably arranged on the inner wall of the support block. A second gear 32 is meshed on one side of the inner wall of the gear ring 31. The top of the second gear 32 passes through the processing table 1, and the top of the second gear 32 is meshed with a third gear 34. The third gear 34 is rotatably connected to the top of the processing table 1. A transmission rod 33 is fixed to the top of the second gear 32, and a propulsion block 35 is fixed to the top of the transmission rod 33. Two groups of the transmission rod 33 and the propulsion block 35 are provided, and are symmetrically distributed at the tops of the second gear 32 and the third gear 34. Another group of the transmission rod 33 is fixed to the top of the third gear 34. A support block 36 is fixed to the top of the processing table 1, and a frame plate 37 is fixed to the top of the support block 36. Both groups of the propulsion blocks 35 are arranged on the inner wall of the frame plate 37.

[0037] by Figure 8 As shown in the figure, when the first motor 3 drives the cylinder 7 to rotate, the first gear 30 can be driven to rotate counterclockwise. When the first gear 30 rotates, the gear ring 31 engaged on one side will be driven to rotate clockwise. By arranging a support block at the bottom of the processing table 1, a limit can be provided for the rotation of the gear ring 31. When the gear ring 31 rotates, the second gear 32 will be driven to rotate counterclockwise. Since the top of the second gear 32 extends out of the processing table 1, the third gear 34 can be driven to rotate clockwise through the second gear 32. When the second gear 32 and the third gear 34 rotate, the two groups of transmission rods 33 and the push blocks 35 set at the tops of the two gears will be driven to rotate respectively, and the two groups of transmission rods 33 and the push blocks 35 rotate in opposite directions, so that the wires between the two groups of push blocks 35 can be transmitted to one side of the elbow mold, so that when the elbow mold is gradually rotated upward, the wires can be continuously transported to one side of the elbow mold, which can improve the efficiency of the electrofusion pipe processing.

[0038] Reference Figure 8-10 The pause assembly includes a fixed plate 39, which is fixedly connected to one side of the support block 36, and a second hydraulic cylinder 40 is fixedly connected to one side of the fixed plate 39, and a top block 41 is fixedly connected to the output end of the second hydraulic cylinder 40, and a slope is provided on the side of the top block 41 away from the second hydraulic cylinder 40, and a short groove is provided at the top of the frame plate 37, and a square plate is inserted into the inner wall of the short groove, and a group of propulsion blocks 35 at the top of the second gear 32 are rotatably connected to the bottom of the square plate, and a top rod is fixedly connected to the top of the square plate, and a top sheet 38 is fixedly connected to one side of the top rod, and the top sheet 38 is arranged on one side of the top block 41.

[0039] When it is necessary to stop conveying wires to one side of the elbow mold, the second hydraulic cylinder 40 can be started, and the second hydraulic cylinder 40 can be used to push the top block 41 to move to one side. Since one side of the top block 41 is a slope, when the top block 41 moves to one side, the top plate 38 and the top rod can be pushed to move upward by the characteristics of the slope. When the top rod and the top plate 38 move upward, the bottom square plate and the second gear 32 will be driven to move upward, and at the same time, a group of transmission rods 33 and the propulsion block 35 at the top of the second gear 32 will be driven to move upward until the bottom of the second gear 32 is moved to the top of the gear ring 31, thereby stopping the conveying of wires to one side of the elbow mold and preventing the problem caused by the gear ring 31 being accidentally touched. When it is necessary to resume conveying wires, the second hydraulic cylinder 40 can be retracted, and the top block 41 can be driven to reset to one side, and the top rod and the top plate 38 will reset downward with gravity until the second gear 32 is meshed with the gear ring 31.

[0040] Reference Fig.10 The cutting assembly includes a slide rod 42, which is fixedly connected to one side of the top block 41. A guide plate 45 is fixedly connected to the top of the processing table 1. A guide groove is provided at the top of the guide plate 45. A slide block is slidably connected to the inner wall of the guide groove. A first cutter 46 is fixedly connected to the top of the slide block. A push rod 43 is fixedly connected to one side of the first cutter 46. A push plate 44 is fixedly connected to the top of the push rod 43. One end of the slide rod 42 is slidably connected to the inner wall of the push plate 44. A second cutter 47 is fixedly connected to the top of the processing table 1.

[0041] When the winding operation is completed on one end of the elbow mold, the second hydraulic cylinder 40 can be started. When the second hydraulic cylinder 40 pushes the top block 41 to one side, it will drive the slide bar 42 on one side of the top block 41 to move together. Since the slide bar 42 slides on the inner wall of the push plate 44, the push plate 44 will be pushed to one side when the slide bar 42 moves, and the push plate 44 will push the push rod 43 and the first cutter 46 to move to one side. Since the slider at the bottom of the first cutter 46 will slide on the inner wall of the guide groove, the movement trajectory of the first cutter 46, the push rod 43 and the push plate 44 will also be limited by the guide groove, which can guide the first cutter 46 to move to one side of the second cutter 47 until the first cutter 46 cooperates with the second cutter 47 to cut the wire.

[0042] Working principle: In order to solve the problem that the mold is not easy to flip during the processing of elbow-type electric fusion pipe fittings, when it is necessary to process the elbow-type electric fusion pipe fittings, one end of the elbow mold can be placed on the top of the clamping table 4, and the positions of the two sets of clamps 5 can be adjusted by adjusting the adjustment screw in the clamping table 4, so that the position of the elbow mold can be fixed at the top of the clamping table 4, and then one end of the wire can be fixed on the elbow mold, and then the first motor 3 can be started, and the top cylinder 7 can be driven to rotate by the first motor 3. When the cylinder 7 rotates, since the side blocks 10 on both sides of the round rod 9 are inserted into the side grooves 8 on the inner wall of the cylinder 7, the round rod 9 will be driven to rotate, and at the same time, the round rod 9 will drive the top threaded sleeve 11 and the clamping table 4 to rotate together. A vertical plate 13 and a side rod 14 are provided at the end, and the side rod 14 slides in the thread groove of the outer wall of the threaded sleeve 11. Therefore, when the thread groove rotates, the position of the side rod 14 on the inner wall of the threaded sleeve 11 will be adjusted, so that the threaded sleeve 11 gradually moves upward during rotation, so that the position of the top clamping platform 4 and the elbow mold can be gradually raised, so that the wire can be gradually wound around the outer wall of the elbow mold from top to bottom, and by providing the sleeve plate 12, a protective effect can be provided for the outer wall of the threaded sleeve 11. When the elbow mold needs to be turned over, the clamping piece 5 on the clamping platform 4 can be released from the fixation of the elbow mold, and then the support platform 15 can be pushed to one side by the first hydraulic cylinder 6, and the support platform 15 can be pushed to one side of the elbow mold, and then the second motor 17 can be started to Figure 5From a perspective, the second motor 17 drives the threaded rod 18 to rotate counterclockwise. When the threaded rod 18 rotates, the collar 21 on its outer wall can slide in the thread groove on the outer wall of the threaded rod 18 through the circular protrusion, so that the collar 21, the clamping block 22 and the guide plate 23 can be moved to one side of the elbow mold. At this time, the bottom of the guide plate 23 slides in the slide groove at the top of the support platform 15, and when the clamping block 22 moves to the outer wall of the elbow mold, the circular protrusion on the inner wall of the collar 21 will slide into the fixed groove 19 at the end of the thread groove, and the position of the bottom of the guide plate 23 will also move to the third opening 27, so that when the threaded rod 18 rotates counterclockwise, the collar 21, the guide plate 23 and the clamping block 22 can move along with the threaded rod 18 rotates counterclockwise together, so that the elbow mold clamped by the clamping block 22 can rotate counterclockwise. When the elbow mold rotates counterclockwise to 270 degrees, the end of the elbow mold that is not wound will be rotated to the top of the clamping table 4, and the guide plate 23 will also be rotated into the first opening 25. The guide plate 23 rotates downward to squeeze the baffle in the first opening 25, and the baffle presses the first spring downward through the rotating shaft until the bottom of the guide plate 23 is rotated to the inner wall of the top plate 24, and the first spring pushes the baffle to reset, so that the position of the first opening 25 can be blocked, and then the second motor 17 can be rotated in the opposite direction to make the second motor 17 drive the threaded rod 18 to rotate clockwise, and when the threaded rod 18 rotates clockwise, the second motor 17 drives the threaded rod 18 to rotate clockwise. When the sleeve 21 is moved, the circular protrusion in the collar 21 will be disengaged from the fixing groove 19, so that the sleeve 21 can slide in the thread groove of the outer wall of the threaded rod 18 through the circular protrusion, so that the sleeve 21, the clamping block 22 and the guide plate 23 move horizontally to the side away from the elbow mold, so that the clamping block 22 is removed from the outer wall of the elbow mold, and when the circular protrusion in the sleeve 21 rotates to the end of the thread groove of the outer wall of the threaded rod 18, the circular protrusion will slide into the inner wall of the straight groove 20, so that the sleeve 21, the clamping block 22 and the guide plate 23 can be driven to rotate clockwise together through the clockwise rotation of the threaded rod 18, and the position of the end of the guide plate 23 is set at the bottom of the second opening 26, so that the guide plate 23 can be rotated clockwise and brought out of the top plate 2 4, and after rotating 270 degrees clockwise, the end of the guide plate 23 is rotated into the fourth opening 28, and the thrust generated by the rotation pushes the inclined block 29 downward to squeeze the second spring until the end of the guide plate 23 rotates into the slide groove at the top of the support platform 15, so that the positions of the clamping block 22, the collar 21 and the guide plate 23 can be reset, and the slide groove is provided with an inclined surface, which will slightly push the position of the guide plate 23 to the side away from the second motor 17, so that the collar 21 at the top of the guide plate 23 can be moved together, so that the circular protrusion on the inner wall of the collar 21 is pushed back from the straight groove 20 into the threaded groove, which is convenient for the next work, and then the support platform 15 can be moved to one side by the first hydraulic cylinder 6 to Figure 8As shown in the figure, when the first motor 3 drives the cylinder 7 to rotate, the first gear 30 can be driven to rotate counterclockwise. When the first gear 30 rotates, the gear ring 31 meshed on one side can be driven to rotate clockwise. By arranging a support block at the bottom of the processing table 1, a limit can be provided for the rotation of the gear ring 31. When the gear ring 31 rotates, the second gear 32 can be driven to rotate counterclockwise. Since the top of the second gear 32 extends out of the processing table 1, the third gear 34 can be driven to rotate clockwise through the second gear 32. When the second gear 32 and the third gear 34 rotate, they will respectively drive the two groups of transmission rods 33 and the propulsion block 35 arranged at the top of the two groups to rotate, and the two groups The transmission rod 33 and the push block 35 rotate in opposite directions, so that the wires between the two sets of push blocks 35 can be transmitted to one side of the elbow mold, so that when the elbow mold is gradually rotated upward, the wires can be continuously transported to one side of the elbow mold, which can improve the efficiency of the electrofusion pipe processing. When it is necessary to stop transporting the wires to one side of the elbow mold, the second hydraulic cylinder 40 can be started to push the top block 41 to move to one side. Since one side of the top block 41 is a slope, when the top block 41 moves to one side, the top plate 38 and the top rod can be pushed to move upward by the characteristics of the slope. When the top rod and the top plate 38 move upward, The square plate at the bottom and the second gear 32 are driven to move upward, and at the same time, a group of transmission rods 33 and a push block 35 at the top of the second gear 32 are driven to move upward until the bottom of the second gear 32 is moved to the top of the gear ring 31, so that the wire feeding to one side of the elbow mold can be stopped, and the problem caused by the gear ring 31 being accidentally touched can be prevented. When it is necessary to resume the wire feeding, the second hydraulic cylinder 40 can be retracted and the top block 41 can be driven to reset to one side, and the top rod and the top plate 38 will reset downward with gravity until the second gear 32 is meshed with the gear ring 31. When the winding operation is completed on one end of the elbow mold, the second hydraulic cylinder 40 can be started. When the second hydraulic cylinder 40 pushes the top block 41 to one side, it will drive the sliding rod 42 on one side of the top block 41 to move together. Since the sliding rod 42 slides on the inner wall of the push plate 44, the sliding rod 42 will push the push plate 44 to move to one side when it moves, and the push plate 44 will push the push rod 43 and the first cutter 46 to move to one side. Since the slider at the bottom of the first cutter 46 will slide on the inner wall of the guide groove, the movement trajectory of the first cutter 46, the push rod 43 and the push plate 44 will also be limited by the guide groove, which can guide the first cutter 46 to move to one side of the second cutter 47 until the first cutter 46 cooperates with the second cutter 47 to cut the wire.
