Description
Technical Field
[0001] This utility model relates to the field of steel pipe processing equipment technology, and more specifically, it relates to a seamless steel pipe punch support device. Background Technology
[0002] The core function of the seamless steel pipe punch support device is to provide precise, stable and reliable support for the steel pipe when the punch performs punching, stamping or other processing on the steel pipe, so as to prevent the steel pipe from deforming or vibrating and to ensure the processing quality. However, the traditional seamless steel pipe punch support device has some shortcomings that affect daily use.
[0003] The primary problem is that the internal support system in traditional seamless steel pipe punch support devices has a complex structure. This complex system structure requires more and more complete components, resulting in high initial installation and commissioning costs. In particular, the hydraulic and pneumatic systems need to be constantly monitored for leaks. Leaks can lead to inaccurate positioning or power loss of the actuator, causing energy loss and component overheating, thus reducing overall efficiency. Furthermore, the complex system has many potential failure points, and locating the fault requires disassembling most of the components, increasing downtime for each maintenance operation.
[0004] More importantly, traditional seamless steel pipe punch support devices lack an ejector mechanism to eject the processed steel pipe. Without this mechanism, the processed steel pipe may become stuck on the support device due to the bonding stress after punching, requiring manual extraction or prying with tools. This not only increases the labor intensity of workers, but also requires operators to reach their hands into the narrow space between the support device and the punch when manually removing the pipe. If the equipment is accidentally started, the downward movement of the punch can cause hand crushing injuries. In addition, the rebound force generated when prying the steel pipe may cause the tool to slip from the hand, resulting in crushing injuries.
[0005] Crucially, traditional seamless steel pipe punch support devices lack external support. During punching, the punch must withstand extremely high axial pressure. Without external support to provide radial constraint from the outside of the punch, the punch is prone to radial runout due to force imbalance, which can easily lead to axial misalignment. This results in excessive deviation of the perpendicularity of the steel pipe end, causing poor sealing during subsequent welding and flange connection, increasing the risk of leakage. Without external support, the friction between the outer side of the punch and the inner wall of the steel pipe will intensify during radial runout. At the same time, the outer wall of the steel pipe may come into direct contact and rub against components such as the equipment frame and feed guide rail, resulting in scratches on the surface of the steel pipe.

The slide groove is fixedly connected to the base and slidably connected to the connecting block and the push block respectively. The push block is movably connected to the connecting block.
[0008] The present invention is further configured such that the external support device includes a bottom block, a top block, a guide rod, a mounting block, and bolts. The bottom block is fixedly connected to the mounting block, the mounting block is fixedly connected to the base by bolts, the bolts are threadedly connected to the mounting block and the base respectively, and the guide rod is fixedly connected to the bottom block and slidably connected to the top block.
[0009] The present invention is further configured such that the base is provided with multiple threaded holes that cooperate with bolts, thereby improving the stability of the support.
[0010] The present invention is further configured such that the base is provided with an extension track, an adjustment column and a pad, the extension track is fixedly connected or slidably connected to the base, the adjustment column is rotatably connected to the pad and threadedly connected to the base, and the pad is movably connected to the extension track, thereby improving the flexibility of use.
[0011] The present invention is further configured such that the slide is provided with a guide rail, the guide rail is fixedly connected to the slide and slidably connected to the connecting block and the push block respectively, thereby improving the stability of movement.
[0012] The present invention is further configured such that the base is provided with a movable component, the movable component including a slide rail, a locking pad and a knob, the knob being rotatably connected to the locking pad and being threadedly connected to the base, the slide rail being fixedly connected to the base and slidably connected to the base, and the slide rail being movably connected to the locking pad, thereby improving the flexibility of use.
[0013] The present invention is further configured such that the top block is provided with a quick positioning device, the quick positioning device including a connecting seat, a limiting block and a ejector pin, the connecting seat being fixedly connected to the top block and the limiting block respectively, and the ejector pin being rotatably connected to the connecting seat and movably connected to the limiting block, thereby improving the convenience of processing.
[0014] (III) Beneficial Effects Compared with the prior art, this utility model provides a seamless steel pipe punch support device, which has the following beneficial effects: 1. A complete and simple internal support device is formed by the tight fit between the base, screw, inner support plate, side plate, and adjusting plate. The distance of the adjusting plate is adjusted by the screw, and the inner diameter support diameter is changed by the compression of the adjusting plate against the inner support plate. The simple structure reduces the processing requirements of complex mating surfaces, and there is no need to pursue extremely high geometric tolerances. Conventional machining equipment can meet production requirements. The simple internal support device reduces the number of transmission components, and there is no need to calibrate the meshing clearance and transmission phase of each component during assembly, reducing the assembly time per cycle. The simple internal support device has fewer failure points, and fault location does not require a large number of disassemblies. Common faults can be diagnosed and repaired in a short time. For steel pipes of different diameters and wall thicknesses, the simple internal support device can meet the processing requirements without replacing multiple sets of related components.
[0015] 2. A complete ejection device is formed by the close cooperation between the top plate, hammer body, slide, connecting block and push block. The push block impacts the connecting block, causing the hammer body to rotate and impact the top plate, thus ejecting the steel pipe from the top plate. The ejection device separates the steel pipe from the mold with a simple push, avoiding the labor cost of pulling by the workers and reducing the scratches caused by using prying tools to forcibly remove the steel pipe when it is difficult to remove. The ejection device allows the steel pipe to be removed quickly, reducing the time that the workers' arms stay under the punch and reducing the possibility of injury caused by human error or machine malfunction.
[0016] 3. A complete external support device is formed by the tight fit between the bottom block, top block, guide rod, mounting block and bolts. The outer diameter of the steel pipe is pressed and supported by the support of the bottom block and the pressure of the weight of the top block. During the stamping, the punch bears axial pressure of hundreds of kilonewtons. The internal support device alone is prone to radial runout due to force imbalance. The external support reduces the radial runout of the steel pipe by constraining the outer diameter of the steel pipe. At the same time, the external support device and the internal support device work together to form a double guarantee of the punch support system. By providing radial constraint from the outer wall of the steel pipe or the outside of the punch, the shortcomings of the internal support device working alone are made up for.

The pop-out device includes a top plate 7, a hammer body 8, a slide groove 9, a connecting block 10, and a push block 11. The top plate 7 has a gap with the base 1 and is movably connected to the hammer body 8. The hammer body 8 is rotatably connected to the base 1 and fixedly connected to the connecting block 10. The slide groove 9 is fixedly connected to the base 1 and slidably connected to the connecting block 10 and the push block 11, respectively. The push block 11 is movably connected to the connecting block 10.
[0023] In a further embodiment of this application, the external support device includes a base block 12, a top block 13, a guide rod 14, a mounting block 15, and bolts 16. The base block 12 is fixedly connected to the mounting block 15, the mounting block 15 is fixedly connected to the base 1 by bolts 16, and the bolts 16 are threadedly connected to the mounting block 15 and the base 1 respectively. The guide rod 14 is fixedly connected to the base block 12 and slidably connected to the top block 13.
[0024] In a further embodiment of this application, the base 1 is provided with a plurality of threaded holes that mate with the bolts 16. By connecting the threaded holes at different positions of the bolts 16, the support position of the base block 12 can be changed.
[0025] In a further embodiment of this application, the base 1 is provided with an extension rail 17, an adjusting column 18 and a pad 19. The extension rail 17 is fixedly connected or slidably connected to the base 1. The adjusting column 18 is rotatably connected to the pad 19 and is threadedly connected to the base 1. The pad 19 is movably connected to the extension rail 17. By rotating the adjusting column 18, the pad 19 can be made to come into close contact with or separate from the extension rail 17, so that the base 1 can be extended, moved and fixed.
[0026] In a further embodiment of this application, the slide 9 is provided with a guide rail 20, which is fixedly connected to the slide 9 and slidably connected to the connecting block 10 and the push block 11 respectively. The movement of the connecting block 10 and the push block 11 is smooth and stable by the limiting of the guide rail 20.
[0027] In a further embodiment of this application, the base 2 is provided with a movable component, which includes a slide rail 21, a locking pad 22 and a knob 23. The knob 23 is rotatably connected to the locking pad 22 and is threadedly connected to the base 2. The slide rail 21 is fixedly connected to the base 1 and slidably connected to the base 2. The slide rail 21 is movably connected to the locking pad 22. By rotating the knob 23, the locking pad 22 is brought into close contact with or separated from the slide rail 21, thereby realizing the movement and fixation of the base 2.
[0028] In a further embodiment of this application, the top block 13 is provided with a quick positioning device, which includes a connecting seat 24, a limiting block 25, and a pin 26. The connecting seat 24 is fixedly connected to the top block 13 and the limiting block 25 respectively. The pin 26 is rotatably connected to the connecting seat 24 and movably connected to the limiting block 25. When the top block 13 is lifted and the pin 26 is rotated and inserted into the punched hole, the steel pipe is pushed forward. The pin 26 will rotate due to the thrust of the hole. Due to the obstruction of the pin 26 by the limiting block 24, the steel pipe cannot move forward. The steel pipe is then punched, and this process is repeated to make the spacing of each hole consistent and to enable quick positioning, thus completing the continuous punching operation at equal intervals.
[0029] In this embodiment, when the device is needed, the entire device is placed below the punch, and the top plate 7 is inserted into the mold sleeve. The steel pipe is then inserted into the mold sleeve, and the length of the base 1 is adjusted so that the side plate 5 is inserted into the other side of the steel pipe. The screw 3 is rotated so that the adjusting plate 6 moves along the screw 3. The inner support plate 4 moves outward to support the inside of the steel pipe by pressing the adjusting plate 6 with different diameters. The adjusting column 18 is tightened so that the pad 19 is in close contact with the extension rail 17 to lock the length of the base 1. Then, the top block 13 contacts the bottom block 12 through the guide rod 14, and the weight of the top block 13 supports the outer wall of the steel pipe. After stamping, after stamping is completed, turn knob 23 to separate locking pad 22 from slide rail 21 to release the restriction. Then turn screw 3 in the opposite direction. The inner support device can be moved from base 1 to the far end along extension track 17 by moving base 2. Then push push block 11 to move along guide rail 20 in slide groove 9 and hit connecting block 10. Since connecting block 10 is connected to hammer body 8 and hammer body 8 is rotatably connected to base 1, the impact of connecting block 10 causes hammer body 8 to rotate and hit top plate 7, causing top plate 7 to vibrate and hit the processed steel pipe, pushing the steel pipe out a distance, and the processed steel pipe can be pulled out.
[0030] More specifically, the support position of the bottom block 12 can be changed by the cooperation of the mounting block 15 and the bolt 16. If it is necessary to continuously and evenly punch holes in the axial direction of the steel pipe, after punching a hole, turn the knob 23 to separate the locking pad 22 from the slide rail 21 and remove the inner support device from the slide rail 22. Support it closely against the outer support device, lift the top block 13 and rotate the ejector pin 26 into the punched hole. Push the steel pipe forward. The ejector pin 26 will rotate due to the thrust of the hole. Due to the obstruction of the ejector pin 26 by the limit block 24, the steel pipe cannot move forward. Punch holes in the steel pipe and punch holes continuously in this manner to make the spacing of each hole consistent and to quickly position it, thus completing the continuous punching operation with equal spacing.
[0031] In summary, when using or running the entire device: place the entire device under the punch and insert the top plate 7 into the mold sleeve. Insert the steel pipe into the mold sleeve and adjust the length of the base 1 so that the side plate 5 is inserted into the other side of the steel pipe. Rotate the screw 3 to move the adjusting plate 6 along the screw 3. The inner support plate 4 moves outward by the compression of the adjusting plate 6 with different diameters to support the inside of the steel pipe. Tighten the adjusting column 18 to make the pad 19 and the extension rail 17 in close contact to lock the length of the base 1. Then, the top block 13 contacts the bottom block 12 through the guide rod 14. The weight of the top block 13 supports the outer wall of the steel pipe. After stamping, turn knob 23 to separate locking pad 22 from slide rail 21 and release the constraint. Then turn screw 3 in the opposite direction. The inner support device can be moved from base 1 to the far end along extension track 17 by moving base 2. Then push push block 11 to move along guide rail 20 in slide groove 9 and hit connecting block 10. Since connecting block 10 is connected to hammer body 8 and hammer body 8 is rotatably connected to base 1, the impact of connecting block 10 causes hammer body 8 to rotate and hit top plate 7, causing top plate 7 to vibrate and hit the processed steel pipe, pushing the steel pipe out a distance, and the processed steel pipe can be pulled out.
[0032] The support position of the bottom block 12 can be changed by the cooperation of the mounting block 15 and the bolt 16. If it is necessary to continuously and evenly punch holes in the axial direction of the steel pipe, after punching a hole, turn the knob 23 to separate the locking pad 22 from the slide rail 21 and remove the inner support device from the slide rail 22. Support it closely against the outer support device, lift the top block 13 and rotate the ejector pin 26 into the punched hole. Push the steel pipe forward. The ejector pin 26 will rotate due to the thrust of the hole. Due to the obstruction of the ejector pin 26 by the limit block 24, the steel pipe cannot move forward. Punch holes in the steel pipe again and punch holes continuously in this way to make the spacing of each hole consistent and to quickly position it, thus completing the continuous punching operation with equal spacing.
[0033] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
