Description

Technical Field

[0001] The present invention relates to the field of seamless pipe processing, and more particularly to a seamless pipe processing and punching mechanism for a heat exchanger. Background Art

[0002] Seamless heat exchanger pipe is a type of pipe widely used in heat exchanger manufacturing. It features a seamless structure and is manufactured through processes such as hot rolling, cold rolling, or cold drawing. A seamless pipe punching mechanism is a specialized device or apparatus used to create holes in seamless steel pipes. These mechanisms are typically designed to precisely drill holes in specific locations on seamless steel pipes to meet the needs of heat exchangers, pipe connections, or other industrial applications.

[0003] The existing punching device limits the seamless pipe by an external limiting component when punching a hole in the seamless pipe, and then moves the drill rig downward to punch the seamless pipe. However, since the seamless pipe used for the heat exchanger is relatively thin, when the drill rig moves downward, the drill bit will apply downward pressure to the seamless pipe when it rotates. In addition, the rotation of the drill bit and the contact with the seamless pipe generate heat, which makes the drilling position easily deformed, resulting in the drilling position collapsing downward during drilling. In severe cases, it may affect the overall shape of the seamless pipe, and the processing effect is not ideal.

[0004] Therefore, a seamless pipe processing and punching mechanism for a heat exchanger is proposed. Summary of the Invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) The tapered block is driven to move by the rectangular rod, so that the inclined block approaches the inner wall of the seamless pipe, and the inclined block has a certain pressure on the seamless pipe. Under the action of multiple inclined blocks, the seamless pipe can be fully fixed from the inside. In this way, when the drill presses down to drill a hole, the inclined block can provide better support force, which can avoid the deformation of the seamless pipe caused by the drill during processing, thereby improving the drilling effect. At the same time, through the movement of multiple inclined blocks, good support force can be provided for seamless pipes of different diameters, thereby improving the applicability of the device.

[0020] (2) The support block is rotated by the one-way bearing, thereby being able to discharge the metal chips remaining inside the circular hole, thereby preventing the metal chips from accumulating inside the circular hole and affecting the next punching effect, thereby improving the use effect.

[0021] (3) When the conical block moves to the right, the limit block is inserted into the limit slot. Because the right side of the conical block is a square rod, the conical block cannot rotate. When the limit block is inserted into the limit slot, the inclined block is in a stable state during operation and will not shake, thereby improving the stability of punching.

[0022] (4) The moving distance of the second slider is limited by the position of the stop block. In this way, when processing multiple seamless pipes, it is only necessary to push the seamless pipe to the right to reach the position where the hole needs to be punched. There is no need to measure the position every time a hole is punched, which improves the working speed. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0036] See also Figure 1-10 A seamless pipe processing and punching mechanism for a heat exchanger includes a workbench 1. A moving rod 5 is fixedly connected to the left side of the upper end of the workbench 1. The moving rod 5 is a driving device. In the existing device, a drilling rig 6 for drilling is fixedly connected to the upper end of the moving rod 5. The moving rod 5 can drive the drilling rig 6 to move up and down, thereby realizing the drilling work. A limit assembly is provided at the upper end of the workbench 1, and the limit assembly is used to support the inner wall of the seamless pipe.

[0037] The limit assembly includes a support plate 7 fixedly connected to the right side of the upper end of the workbench 1. The support plate 7 is used for supporting. The left side of the support plate 7 is fixedly connected to a cross bar 9. The cross bar 9 has a certain supporting force and is relatively stable. It will not shake during work. A support block 10 is provided on the left side of the cross bar 9. The support block 10 is a circular setting. When working, the seamless pipe to be punched passes through the support block 10 so that the support block 10 is located inside the seamless pipe. The interior of the cross bar 9 is slidably connected to a rectangular rod 12, and the rectangular rod 12 can slide left and right inside the cross bar 9. The right side of the support plate 7 is fixedly connected to a motor 8. The motor 8 is a driving device. In the prior art, the output end of the motor 8 is fixedly connected to a first threaded rod 13. The motor 8 drives the first threaded rod 13 to rotate. The rod wall of the first threaded rod 13 is threadedly connected to the internal thread of the rectangular rod 12. The rotation of the first threaded rod 13 causes the rectangular rod 12 to move. A conical block 23 is provided on the left side of the rectangular rod 12. The movement of the rectangular rod 12 drives the conical block 23 to move, and the support block 10 The first slide 21 is evenly provided inside, and the first slide 21 is slidably connected to the first slider 25 inside the first slide 21. The first slider 25 can move inside the first slide 21. One side of the first slider 25 is fixedly connected to the first spring 22. The first spring 22 enables the first slider 25 to return to its original position after moving. The left side of the first slider 25 is fixedly connected to the inclined block 18. The inclined block 18 moves to drive the first slider 25 to move. The inclined block 18 is slidably connected to the outer side of the support block 10. The inclined block 18 is provided with a plurality of settings. The opposite sides of the upper and lower inclined blocks 18 are provided with round holes 33. The left side of the upper end of the workbench 1 is slidably connected to the dirt collection box 4. The dirt collection box 4 is used to place the generated debris. The left side of the support block 10 is fixedly connected to the rubber block 14. The rubber block 14 is made of soft material and can fit the inner wall of seamless pipes with different inner diameters. When the seamless pipe is taken out after processing, the debris on the inner wall of the seamless pipe can be pushed to the right relative to the seamless pipe by the rubber block 14, so as to avoid impurities generated during drilling remaining in the interior of the seamless pipe.

[0038] When working, the seamless pipe that needs to be punched passes through the outer side of the support block 10 and the cross bar 9, and is sleeved on the outer side of the cross bar 9 and the support block 10. At this time, the motor 8 works, and the output end of the motor 8 drives the first threaded rod 13 to rotate. The rotation of the first threaded rod 13 causes the rectangular rod 12 to move to the right, and the movement of the rectangular rod 12 drives the conical block 23 to move to the right. When the conical block 23 moves to the right, it contacts the inclined block 18. The inclined surface of the conical block 23 contacts the inclined surface of the inclined block 18, pushing the inclined block 18 to move. The movement of the inclined block 18 drives the first slider 25 to move inside the first slide 21. Multiple inclined blocks 18 move and fit the inner wall of the seamless pipe. At this time, the moving rod 5 drives the drill rig 6 to move downward and cooperate with the circular hole 33 to punch the seamless pipe. After the punching is completed, the motor 8 drives The rectangular rod 12 is moved to the left, thereby causing the tapered block 23 to move to the left. At this time, the inclined block 18 is reset under the action of the first spring 22 and retracted into the inside of the support block 10. In this way, when drilling, the tapered block 23 is driven to move by the rectangular rod 12, so that the inclined block 18 is close to the inner wall of the seamless pipe, and the inclined block 18 has a certain pressure on the seamless pipe. Under the action of multiple inclined blocks 18, it can fully fix the seamless pipe from the inside. In this way, when the drill rig 6 presses down to drill, the inclined block 18 can provide better supporting force, which can avoid the deformation of the seamless pipe caused by the drill rig 6 during processing, thereby improving the drilling effect. At the same time, through the movement of multiple inclined blocks 18, it can provide good supporting force for seamless pipes of different diameters, thereby improving the applicability of the device.

[0039] like Figure 2-7 As shown, the right side of the support block 10 is rotatably connected to the left side of the cross bar 9, and the left side of the rectangular rod 12 is fixedly connected to the second threaded rod 26. The left and right movement of the rectangular rod 12 drives the second threaded rod 26 to move, and the second threaded rod 26 drives the tapered block 23 to move. The outer side of the second threaded rod 26 is threadedly connected to a one-way bearing 27. The one-way bearing 27 is an existing component. The inner ring and the outer ring can rotate relative to each other in one direction, and the inner ring and the outer ring can be locked in the other direction. The outer ring of the one-way bearing 27 is connected to the inside of the support block 10, and the left side of the second threaded rod 26 is movably connected to the tapered block 23.

[0040] When the rectangular rod 12 moves to the right, it drives the second threaded rod 26 to move to the right. The movement of the second threaded rod 26 causes the inner ring of the one-way bearing 27 to rotate. When the second threaded rod 26 moves to the right, the inner ring and outer ring of the one-way bearing 27 rotate relative to each other. When the rectangular rod 12 moves to the left, the inner ring and outer ring of the one-way bearing 27 are in a locked device. In this way, the second threaded rod 26 moves to the left, causing the one-way bearing 27 to rotate as a whole, thereby causing the support block 10 to rotate, and the rotation angle is 180 degrees. In this way, during each operation, the support block 10 is rotated through the one-way bearing 27, thereby being able to discharge the metal chips remaining inside the circular hole 33, thereby preventing the metal chips from accumulating inside the circular hole 33 and affecting the next punching effect.

[0041] like Figure 4 and Figure 6 As shown, a square rod 29 is slidably connected to the interior of the second threaded rod 26. The left side of the square rod 29 is fixedly connected to the right side of the tapered block 23. The right side of the square rod 29 is fixedly connected to a round block 44. The wall of the square rod 29 is provided with a second spring 37.

[0042] When supporting and fixing seamless pipes with different inner diameters, the moving distance of the conical block 23 is different, but the second threaded rod 26 needs to move the same distance each time to ensure the stable rotation of the support block 10. Therefore, the rectangular rod 12 drives the second threaded rod 26 to move the same distance each time. When the second threaded rod 26 moves, it compresses the second spring 37. The second spring 37 has a thrust on the round block 44, thereby pulling the square rod 29 to move, and the square rod 29 drives the conical block 23 to move.

[0043] like Figure 3 、 Figure 7 and Figure 10 As shown, the outer side of the left side of the conical block 23 is evenly provided with a limiting groove 24, and one side of the lower end of the inclined block 18 is fixedly connected to the limiting block 43. When the conical block 23 moves to the right, the left side of the limiting block 43 is stuck in the inner part of the limiting groove 24. It should be noted that the left side of the limiting block 43 is set at an acute angle, and the outer ring of the one-way bearing 27 is rotatably connected to the inner part of the support block 10. The outer ring of the one-way bearing 27 is fixedly connected to the return spring 28, and one end of the return spring 28 is fixedly connected to the support block 10.

[0044] When the conical block 23 moves to the right, the limit block 43 is stuck in the inside of the limit groove 24. Because the right side of the conical block 23 is the square rod 29, the conical block 23 cannot rotate. When the limit block 43 is stuck in the inside of the limit groove 24, the inclined block 18 is in a stable state during operation and will not shake, thereby improving the stability of punching. When the second threaded rod 26 moves to the left, the inclined block 18 cannot rotate. At this time, when the one-way bearing 27 rotates, the return spring 28 is deformed. When the limit block 43 disengages from the limit groove 24, the support block 10 is rotated under the action of the elastic force of the return spring 28, thereby ensuring the normal operation.

[0045] like Figure 6 and Figure 7 As shown, circular grooves 31 are provided at the upper and lower positions on the left side of the crossbar 9. A third spring 32 is fixedly connected to the inside of the circular groove 31. A protrusion 30 is fixedly connected to the left side of the third spring 32. The sliding of the protrusion 30 is arranged inside the circular groove 31. The left side of the protrusion 30 is embedded in the right side of the support block 10. The third spring 32 has a certain thrust on the protrusion 30, so that the protrusion 30 and the support block 10 have a certain friction force. In this way, when no other external force is applied, the support block 10 can be in a stable state.

[0046] like Figure 6 As shown, the circular hole 33 is slidably connected to the metal block 20, and the inner walls of the circular hole 33 are fixedly connected to the clamping blocks 19 on both sides. When the support block 10 rotates, the circular hole 33 at the upper end faces downward. At this time, the metal block 20 moves downward under the action of gravity, pushing the metal chips inside the circular hole 33, improving the chip removal effect, and limiting the metal block 20 by the clamping blocks 19.

[0047] like Figure 2 and Figure 5 As shown, the left side of the upper end of the workbench 1 is slidably connected to a vertical rod 3, the upper end of the vertical rod 3 is fixedly connected to the arc block 2, the internal thread of the vertical rod 3 is connected to the third threaded rod 15, the third threaded rod 15 is rotatably connected to the inside of the workbench 1, the lower end of the third threaded rod 15 is fixedly connected to the first bevel gear 16, the left side of the workbench 1 is rotatably connected to a turntable, and the right side of the turntable is fixedly connected to a second bevel gear 17 meshing with the first bevel gear 16;

[0048] Rotating the turntable causes the second bevel gear 17 to rotate, which in turn causes the first bevel gear 16 to rotate. The rotation of the first bevel gear 16 drives the third threaded rod 15 to rotate. The third threaded rod 15 causes the vertical rod 3 to drive the arc block 2 to move up and down. Appropriate adjustments are made according to seamless pipes of different diameters, and appropriate support is provided by the arc block 2.

[0049] like Figure 2 and Figure 4As shown, the upper end of the workbench 1 is provided with a second slide groove 34, and the interior of the second slide groove 34 is slidably connected to a second slider 39, and the second slider 39 moves inside the second slide groove 34. The right side of the second slider 39 is fixedly connected to a fourth spring 45, and the fourth spring 45 has a rightward thrust on the second slider 39. A placement block 40 is provided at the upper end of the second slider 39, and one end of the seamless pipe is placed on the upper end of the placement block 40. The workbench 1 is located at the lower end of the second slide groove 34 and is provided with a rectangular groove 35. The interior of the rectangular groove 35 is slidably connected to a moving block 36, and the moving block 36 moves left and right inside the rectangular groove 35. The upper end of the moving block 36 is fixedly connected to a stopper 38. The rectangular groove 35 The fourth threaded rod 46 is connected to the internal rotation of the fourth threaded rod 46, and the fourth threaded rod 46 is connected to the internal thread of the moving block 36. By rotating the fourth threaded rod 46, the moving block 36 moves inside the rectangular groove 35. The upper end of the workbench 1 is provided with a scale 11, which is convenient for viewing the distance moved by the right side of the seamless pipe. The upper end of the second slider 39 is slidably connected to the square block 41, and the lower end of the square block 41 is fixedly connected to the fifth spring 42. The fifth spring 42 has a supporting force on the square block 41, so that the placement block 40 can provide supporting force to the right side of the seamless pipe. The left side of the placement block 40 is tilted. The tilted setting can guide the right side of the seamless pipe, thereby acting on seamless pipes of different diameters.

[0050] The placement block 40 is provided to provide support for the seamless pipe when placing it, and then push the seamless pipe to the right to move it to the position where a hole is required. Under the action of the second slider 39, the seamless pipe can move stably, making loading more convenient. At the same time, by rotating the fourth threaded rod 46, the moving block 36 moves inside the rectangular groove 35. The movement of the moving block 36 drives the stopper 38 to move. The moving distance of the second slider 39 is limited by the position of the stopper 38. The stopper 38 points to the scale 11, which is convenient for observing the adjustment distance. In this way, when processing multiple seamless pipes, it is only necessary to push the seamless pipe to the right to reach the position where a hole is required. There is no need to measure the position every time a hole is punched, which improves the work speed.

[0051] Working principle: When working, the seamless pipe that needs to be punched passes through the outside of the support block 10 and the cross bar 9, and is sleeved on the outside of the cross bar 9 and the support block 10. At this time, the motor 8 is working, and the output end of the motor 8 drives the first threaded rod 13 to rotate. The rotation of the first threaded rod 13 causes the rectangular rod 12 to move to the right, and the movement of the rectangular rod 12 drives the conical block 23 to move to the right. When the conical block 23 moves to the right, it contacts the inclined block 18. The inclined surface of the conical block 23 contacts the inclined surface of the inclined block 18, pushing the inclined block 18 to move. The movement of the inclined block 18 drives the first slider 25 to move inside the first slide 21. Multiple inclined blocks 18 move and fit into the inner wall of the seamless pipe. At this time, the moving rod 5 drives the drill rig 6 to move downward and cooperate with the circular hole 33 to punch the seamless pipe. After the punching is completed, the motor 8 drives the rectangular rod 12 to move to the left, thereby causing the tapered block 23 to move to the left. At this time, the inclined block 18 is reset under the action of the first spring 22 and retracted into the inside of the support block 10. In this way, when drilling, the tapered block 23 is driven to move by the rectangular rod 12, so that the inclined block 18 is close to the inner wall of the seamless pipe, and the inclined block 18 has a certain pressure on the seamless pipe. Under the action of multiple inclined blocks 18, it can fully fix the seamless pipe from the inside. In this way, when the drill rig 6 presses down to drill, the inclined block 18 can provide better supporting force, which can avoid the deformation of the seamless pipe caused by the drill rig 6 during processing, thereby improving the drilling effect. At the same time, through the movement of multiple inclined blocks 18, it can provide good supporting force for seamless pipes of different diameters, thereby improving the applicability of the device.

[0052] Furthermore, when the rectangular rod 12 moves to the right, it drives the second threaded rod 26 to move to the right. The movement of the second threaded rod 26 causes the inner ring of the one-way bearing 27 to rotate. When the second threaded rod 26 moves to the right, the inner ring and outer ring of the one-way bearing 27 rotate relative to each other. When the rectangular rod 12 moves to the left, the inner ring and outer ring of the one-way bearing 27 are in a locked device. In this way, the second threaded rod 26 moves to the left, causing the one-way bearing 27 to rotate as a whole, thereby causing the support block 10 to rotate, and the rotation angle is 180 degrees. In this way, during each operation, the support block 10 is rotated by the one-way bearing 27, thereby being able to discharge the metal chips remaining inside the circular hole 33, thereby preventing the metal chips from accumulating inside the circular hole 33 and affecting the next drilling effect.

[0053] Furthermore, when supporting and fixing seamless pipes of different inner diameters, the moving distance of the tapered block 23 is different, but the second threaded rod 26 needs to move the same distance each time to ensure the stable rotation of the support block 10. Therefore, the rectangular rod 12 drives the second threaded rod 26 to move the same distance each time. When the second threaded rod 26 moves, it compresses the second spring 37. The second spring 37 exerts a thrust on the round block 44, thereby pulling the square rod 29 to move, and the square rod 29 drives the tapered block 23 to move.

[0054] Furthermore, when the conical block 23 moves to the right, the limit block 43 is stuck in the inner part of the limit groove 24. Because the right side of the conical block 23 is the square rod 29, the conical block 23 cannot rotate. When the limit block 43 is stuck in the inner part of the limit groove 24, the inclined block 18 is in a stable state during operation and will not shake, thereby improving the stability of punching. When the second threaded rod 26 moves to the left, the inclined block 18 cannot rotate. At this time, when the one-way bearing 27 rotates, the return spring 28 is deformed. When the limit block 43 disengages from the limit groove 24, the elastic force of the return spring 28 causes the support block 10 to rotate, thereby ensuring normal operation.

[0055] Furthermore, the placement block 40 is provided to provide support for the seamless pipe when placing it, and then push the seamless pipe to the right to move it to the position where a hole is required. Under the action of the second slider 39, the seamless pipe can move stably, making loading more convenient. At the same time, by rotating the fourth threaded rod 46, the moving block 36 moves inside the rectangular groove 35, and the movement of the moving block 36 drives the stopper 38 to move. The moving distance of the second slider 39 is limited by the position of the stopper 38, and the stopper 38 points to the scale 11, which is convenient for observing the adjustment distance. In this way, when processing multiple seamless pipes, it is only necessary to push the seamless pipe to the right to reach the position where a hole is required. There is no need to measure the position every time a hole is punched, which improves the work speed.
