Description

Technical Field

[0001] The utility model belongs to the technical field of plug disassembly, and specifically relates to a disassembly fixture for a plug of a piercing mill. Background Art

[0002] The plug of a piercing mill is a key component in the piercing process; it is usually made of high-strength alloy steel, with a conical or specific curve shape. The working cone surface at the front end of the plug directly contacts the inside of the tube blank and bears huge pressure and friction during the piercing process; the surface of the plug is precisely machined to ensure good wear resistance and dimensional accuracy; when the piercing mill is in use, the plug of the piercing mill needs to be replaced regularly, so a disassembly fixture is required to fix the plug and perform disassembly.

[0003] The disassembly fixture for the plug of a piercing mill usually consists of a fixed seat, clamping arms, adjusting bolts, etc.; the fixed seat provides stable support, and the clamping arms can be flexibly adjusted in the opening and closing degree through the adjusting bolts to clamp the plug; its principle is to fix the fixture in a suitable position, adjust the clamping arms to tightly clamp the plug of the piercing mill, and use the action of mechanical force to overcome the connection force between the plug and the components of the piercing mill; when sufficient external force is applied, the plug can be safely and smoothly disassembled from the piercing mill.

[0004] When the existing plug of a piercing mill is disassembled, a crane is needed to fix the plug for disassembly. Therefore, a large amount of manpower and material resources are required during loading and unloading, and the operation of fixing with a crane will cause the end of the plug of the piercing mill to tilt up. As a result, the plug may get stuck inside the piercing mill, increasing the disassembly difficulty. Moreover, when disassembling the plugs of some large-sized piercing mills, the plugs are usually relatively heavy. If appropriate safety measures are not taken during the disassembly process, safety accidents may occur. Therefore, a disassembly fixture for a plug of a piercing mill is proposed to solve the above problems. Summary of the Utility Model

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Please refer to Figures 1-5 As shown in the figure, a disassembly fixture for a piercing machine mandrel includes a support table 1. A first chute 2 is opened inside the support table 1. A first slider 21 is slidably connected inside the first chute 2. A clamping structure is provided at the top of the first slider 21. The clamping structure includes a placement plate 5. An object inlet 20 is opened at the center of the placement plate 5. A second pull rod 4 is welded to one side of the object inlet 20. An annular through hole is opened inside the placement plate 5. A fixed ring 24 is provided on one side of the annular through hole inside the placement plate 5. Six third chutes 25 are opened on one side of the fixed ring 24. Six second sliders 26 are slidably connected inside the third chutes 25. A fixed column 27 is welded to one side of the second slider 26. The other end of the fixed column 27 is welded to a clamping plate 28. An activity ring 22 is provided between the clamping plate 28 and the second slider 26. Six second chutes 23 are opened inside the activity ring 22. The fixed column 27 is slidably connected to the second chute 23. The through holes at the centers of the fixed ring 24 and the activity ring 22 communicate with the object inlet 20. A first pull rod 3 is welded to the top of the activity ring 22. When disassembling the mandrel, at this time, the operator pushes the device to insert the mandrel into the object inlet 20. At this time, the activity ring 22 is rotated by pulling the first pull rod 3. At this time, the fixed column 27 is pushed to move along the third chute 25 through the second chute 23 inside the activity ring 22, so that the clamping plate 28 on the other side clamps the mandrel. Then, the operator holds the second pull rod 4 on one side and the first pull rod 3 on the other side to pull the mandrel. At this time, the mandrel is taken out, and the mandrel is taken away from the piercing machine through the clamping structure by the first slider 21 moving along the first chute 2, thereby completing the disassembly of the mandrel.

[0020] On both sides of the bottom of the support table 1, the fourth connecting ear 16 and the third connecting ear 15 are welded. Inside the third connecting ear 15 and the fourth connecting ear 16, a connecting rod 19 is connected. At the bottom of the connecting rod 19, a second connecting ear 14 and a first connecting ear 13 are connected. At the bottom of the second connecting ear 14 and the first connecting ear 13, a tooth block 17 is welded. At the bottom of the tooth block 17, there is a serrated plate. Outside the tooth block 17, there is a support base 6. Inside the support base 6, there is a first slide rail 12. Around the tooth block 17, there are two rows of cross beams 11. The cross beams 11 are slidably connected to the first slide rail 12. Inside the support base 6, there is a rectangular dug hole. At the bottom of the rectangular dug hole inside the support base 6, a spring 10 is welded. At the other end of the spring 10, there is a support block 9. At the top of the support block 9, a rack 18 is welded. The rack 18 is meshed with the tooth block 17. At the bottom side of the support block 9, a pedal 8 is welded. The pedal 8 is placed outside the support base 6. At the four corners of the bottom of the support base 6, there are four groups of rollers 7. When adjusting the height of the device, at this time, the operator steps on the pedal 8. At this time, the pedal drives the support block 9 to descend, and thus the support block 9 is separated from the tooth block 17. At this time, the support table 1 is lifted. At the same time, the first connecting ear 13 and the second connecting ear 14 start to move along the track of the first slide rail 12, and thus the device is raised, and thus the height of the device is adjusted. After that, the pedal 8 is released. At this time, under the push of the spring 10, the support block 9 rises. Then, the positions of the two connecting rods 19 are fixed by the meshing of the rack 18 at the top and the tooth block 17. Thus, the adjustment operation of the height of the device is completed. After that, the top head can be inserted into the material inlet 20 and the disassembly operation can be carried out.

[0021] Working principle: When carrying out the disassembly operation of the top head, at this time, the operator pushes the device to insert the top head into the material inlet 20. At this time, by pulling the first pull rod 3, the movable ring 22 is rotated. At this time, by pushing the fixed column 27 to move along the third slide groove 25 through the second slide groove 23 inside the movable ring 22, the clamping plate 28 on the other side clamps the top head. Then, the operator holds the second pull rod 4 on one side and the first pull rod 3 on the other side to pull the top head. At this time, the top head is taken out, and through the way that the first slider 21 moves along the first slide groove 2, the top head is taken away from the punching machine by the clamping structure, and thus the disassembly of the top head is completed. When adjusting the height of the device, at this time, the operator steps on the pedal 8. At this time, the pedal drives the support block 9 to descend, and thus the support block 9 is separated from the tooth block 17. At this time, the support table 1 is lifted. At the same time, the first connecting ear 13 and the second connecting ear 14 start to move along the track of the first slide rail 12, and thus the device is raised, and thus the height of the device is adjusted. After that, the pedal 8 is released. At this time, under the push of the spring 10, the support block 9 rises. Then, the positions of the two connecting rods 19 are fixed by the meshing of the rack 18 at the top and the tooth block 17. Thus, the adjustment operation of the height of the device is completed. After that, the top head can be inserted into the material inlet 20 and the disassembly operation can be carried out.
