Description

Technical Field

[0001] The invention relates to the technical field of friction welding of stainless steel pipes, in particular to a friction welding anti-deviation device for stainless steel pipes. Background Art

[0002] Friction welding of stainless steel pipes is a welding method that connects two stainless steel pipes to each other through friction heat and pressure. It is a solid-state welding technology that does not require filler materials or external heating sources. The principle of friction welding is to use the friction heat generated by the relative friction movement between the two pipes to heat the contact surface and apply a certain pressure to connect them together.

[0003] During the friction welding of stainless steel pipes, debris will be generated due to some factors (for example, if the friction force is too large, the friction between the welding heads will become intense, which will cause debris on the surface of the welding head, or there will be large defects, oxide layers or foreign matter on the surface of the welding head, and debris will also be generated during friction). If these debris are not removed in time, they will not only accumulate around the weld during the welding process, affecting the welding process and causing the stainless steel pipe to deviate, but also the presence of debris will interfere with the formation process of the welding head, resulting in irregular shapes of the welding joints, pits or other defects, thereby affecting the structural integrity of the welding joints and weakening the welding strength of the joints;

[0004] Secondly, during friction welding of stainless steel pipes, the pressure will cause the stainless steel pipes to shake normally, and the staff cannot understand the shaking amplitude of the stainless steel pipes. If the shaking amplitude is too large and the staff does not discover it in time, it will not only cause uneven heating of the weld joint, affecting the quality of the weld head, causing uneven melting and solidification of the weld head, causing irregular weld morphology, cracks or pores and other welding defects, but also the shaking during the welding process will cause structural deformation or fracture of the weld joint, reducing the strength of the weld joint.

[0037] In this embodiment, Figure 4As shown, the debris cleaning mechanism 5 includes a cam ring 507, which is fixedly connected to the side of the rotating base 3 away from the welding machine body 2, and a horizontal plate 501 is arranged above the cam ring 507, and the horizontal plate 501 is vertically slidably connected between the two second through-slots 9, and the lower end surface of the horizontal plate 501 is symmetrically fixedly connected with a first spring 508, and the first spring 508 is fixedly connected to the bottom of the second through-slot 9 at one end away from the horizontal plate 501. When the rotating base 3 rotates, it can drive the cam ring 507 to rotate synchronously, and push the horizontal plate 501 to move upward in the second through-slot 9, thereby pulling the first spring 508 connected between the horizontal plate 501 and the second through-slot 9, and when the cam ring 507 and the horizontal plate 501 are separated, the rebound force of the first spring 508 will pull the horizontal plate 501 to slide downward in the second through-slot 9, and so on and so forth, which will drive the horizontal plate 501 to reciprocate up and down in the second through-slot 9.

[0038] In this embodiment, Figure 5 and Figure 6 As shown, the debris cleaning mechanism 5 also includes a jet box 503, which is horizontally slidably connected between the vertical plates 4, and the jet box 503 is equidistantly provided with air inlet holes 504 at one end away from the rotating base 3, and the lower end surface of the jet box 503 is equidistantly provided with air outlet holes 512, and both the air inlet holes 504 and the air outlet holes 512 are provided with one-way valves, and the gas can enter the interior of the jet box 503 through the air inlet holes 504 and be discharged from the air outlet holes 512, thereby being able to blow away the debris at the welding joint below the jet box 503.

[0039] In this embodiment, Figure 5 As shown, a piston plate 511 is vertically slidably connected inside the jet box 503, a lifting plate 510 is fixedly connected to the upper end surface of the piston plate 511, a piston rod 509 is symmetrically fixedly connected to the lower end surface of the lifting plate 510, the lower ends of the piston rods 509 are all penetrated and slidably connected to the jet box 503, the lower ends of the piston rods 509 are fixedly connected to the telescopic plates 502, the telescopic plates 502 are fixedly connected to the side of the transverse plate 501 away from the rotating base 3, when the transverse plate 501 moves up and down in the second through groove 9, the telescopic plate 502, the piston rod 509 and the lifting plate 510 can drive the piston plate 511 to move up and down inside the jet box 503, thereby changing the flow direction of the gas inside the jet box 503.

[0040] In this embodiment, Figure 2 and Figure 6As shown, a vertical slot 513 is provided on the side of the jet box 503 away from the rotating base 3, and a lifting frame 505 is vertically slidably connected in the vertical slot 513. The lower end surface of the lifting frame 505 is symmetrically fixedly connected with a clamping column 506, and the clamping column 506 is clamped with the positioning hole 7. When the lifting frame 505 is driven to move on the side wall of the jet box 503 through the vertical slot 513, the clamping column 506 and the positioning hole 7 can be driven to separate or clamp with each other, so that the staff can adjust the position of the jet box 503 between the vertical plates 4 and stabilize it.

[0041] In the prior art, during the friction welding of stainless steel pipes, debris will be generated due to some factors. If these debris are not removed in time, they will not only accumulate around the weld during the welding process, affecting the welding process and causing the stainless steel pipe to deviate, but also the existence of debris will interfere with the formation process of the weld joint, resulting in irregular shape of the weld joint, pits or other defects, thereby affecting the structural integrity of the weld joint and weakening the welding strength of the joint. Compared with the prior art, during the friction welding of stainless steel pipes, air can be blown intermittently at the weld joint to remove the debris remaining around the weld, which not only avoids the deviation of the stainless steel pipe due to the influence of the debris, ensures the quality and integrity of the stainless steel pipe weld, but also keeps the welding area clean, which is conducive to forming a uniform weld joint at the weld head;

[0042] Secondly, by means of the mutually clamping connection of the arranged clamping column 506 and the positioning hole 7, the position of the jet box 503 between the two vertical plates 4 can be adjusted and stabilized according to the position of the welding head, so that the jet box 503 can always be located above the welding head, which not only improves the application scope of the jet box 503 and can clean the welding heads in different positions, but also ensures the stability of the jet box 503 during operation, maintains a stable airflow, helps stabilize the heat distribution and welding speed of the stainless steel pipe, thereby improving the stability and consistency of the welding quality.

[0043] In other aspects, this embodiment also provides a deviation warning mechanism 6 for monitoring the shaking amplitude of the stainless steel pipe during the friction welding process, such as Figure 1 and Figure 7 As shown, the deviation warning mechanism 6 includes symmetrically arranged limit rings 604 , and the limit rings 604 are fixedly connected to the sides close to the vertical plate 4 with sliding columns 605 , and the sliding columns 605 are all penetrated and slidably connected to the vertical plate 4 .

[0044] In this embodiment, Figure 7As shown, the lower end surface of the limit ring 604 is rotatably connected to the connecting rod 606, and the end of the connecting rod 606 away from the limit ring 604 is rotatably connected to the lifting block 607, and the lifting block 607 is vertically slidably connected to the first through groove 8, and the bottom of the first through groove 8 is fixedly connected to a button 608, and the side of the vertical plate 4 away from the limit ring 604 is fixedly connected to the alarm light 603, and the buttons 608 are electrically connected to the alarm light 603. When the stainless steel pipe is offset, it will push the limit ring 604 to move synchronously. During the movement of the limit ring 604, the lifting block 607 can be pushed downward in the first through groove 8 through the connecting rod 606, and contact the button 608 connected to the bottom of the first through groove 8, so as to turn on the alarm light 603 to work.

[0045] In this embodiment, Figure 7 As shown, the end of the sliding column 605 away from the limiting ring 604 is fixedly connected with a disc 601, and the side of the disc 601 close to the vertical plate 4 is fixedly connected with a second spring 602. The end of the second spring 602 away from the disc 601 is fixedly connected to the side of the vertical plate 4. The second spring 602 is sleeved on the outer surface of the sliding column 605. Through the rebound force of the second spring 602, the disc 601 can be pulled to push the sliding column 605 to slide close to the center on the vertical plate 4, so as to ensure that the limiting ring 604 connected to the end of the sliding column 605 away from the disc 601 is always in contact with the surface of the stainless steel pipe.

[0046] In the prior art, during friction welding of stainless steel pipes, the pressure will cause the stainless steel pipes to shake normally, and the staff cannot understand the shaking amplitude of the stainless steel pipes. If the shaking amplitude is too large and the staff does not discover it in time, it will not only cause uneven heating of the welding joint, affecting the quality of the welding head, causing uneven melting and solidification of the welding head, and causing welding defects such as irregular weld morphology, cracks or pores, but also the shaking during the welding process will cause structural deformation or fracture of the welding joint, reducing the strength of the welding joint. Compared with the prior art, when the shaking amplitude of the stainless steel pipe is too large, the staff can be reminded in time, which not only makes it easier for the staff to adjust the position and stability of the stainless steel pipe, but also ensures that the welding position is accurate and uniform, avoiding offset, and avoiding welding defects in the stainless steel pipe welding head, thereby ensuring the strength and integrity of the welding joint and improving the aesthetics of the welding joint.

[0047] The working process and principle involved in the overall content of the above embodiment are as follows:

[0048] When the staff needs to friction weld the two stainless steel pipes, first one of the stainless steel pipes is passed through the limit rings 604 and fixed on the rotating base 3, and then the other stainless steel pipe is fixed on the press, the two stainless steel pipes are welded together at the joints, and pressure is applied. At this time, the staff can lift the lifting frame 505 upwards, and slide upward synchronously on the side wall of the jet box 503 through the vertical groove 513 opened on the side wall of the jet box 503. During the rising process of the lifting frame 505, the clamping column 506 symmetrically connected to the lower end face can be driven to slide out of the positioning hole 7 opened on the upper end face of the vertical plate 4. When the clamping column 506 and the positioning hole 7 are completely separated, the staff can pull the jet box 503 so that the jet box 503 is between the two vertical plates. The plates 4 are moved horizontally to the top of the welding joint. When the position adjustment of the jet box 503 is completed, the staff can press down the lifting frame 505 to make the clamping column 506 slide into the positioning hole 7 again, so as to stabilize the position of the jet box 503 between the two vertical plates 4. This not only improves the application range of the jet box 503 and can clean the welding heads at different positions, but also ensures the stability of the jet box 503 during operation, maintains a stable airflow, helps stabilize the heat distribution and welding speed of the stainless steel pipe, thereby improving the stability and consistency of the welding quality. Finally, the staff opens the welding machine body 2 and drives the rotating base 3 to drive one of the stainless steel pipes to rotate, and rotate and rub with the other stainless steel pipe to fuse;

[0049] When the rotating base 3 rotates on the welding machine body 2, the cam ring 507 connected to the side of the rotating base 3 away from the welding machine body 2 will be driven to rotate synchronously, pushing the horizontal plate 501 attached to the top of the cam ring 507 to slide upward in the second through groove 9, and pulling the first spring 508 connected between the horizontal plate 501 and the second through groove 9. During the rising process of the horizontal plate 501, the telescopic plate 502 can be used to push the piston rod 509 to slide synchronously into the jet box 503, driving the lifting plate 510 connected to the upper end of the piston rod 509 to rise synchronously. When the lifting plate 510 rises, it will pull the piston plate 511 connected to the lower end surface to slide synchronously upward in the jet box 503, thereby the jet box 50 The external air is sucked into the jet box 503 through the air inlet 504. When the protruding part of the cam ring 507 is away from the horizontal plate 501, the horizontal plate 501 is pulled to slide downward in the second through groove 9 by the rebound force of the first spring 508, and the air sucked into the jet box 503 is ejected from the air outlet 512 through the telescopic plate 502, the piston rod 509, the lifting plate 510 and the piston plate 511 to the welding joint below, so as to remove the debris left around the weld, which not only avoids the stainless steel pipe from being deflected by the debris, but also ensures the quality and integrity of the stainless steel pipe weld, and can keep the welding area clean, so as to form a uniform welding joint at the welding head;

[0050] When the rotating base 3 drives one of the stainless steel tubes to rotate, the stainless steel tube will shake slightly due to the pressure, and come into contact with the limiting rings 604 on both sides, pushing the limiting rings 604 to drive the sliding column 605 to slide on the vertical plate 4. During the movement of the sliding column 605, the disc 601 connected to one end of the sliding column 605 away from the limiting ring 604 will pull the second spring 602 connected between the disc 601 and the vertical plate 4. When the stainless steel tube and the limiting ring 604 are separated, the rebound force of the second spring 602 will push the disc 601 to drive the sliding column 605 to move in the opposite direction again, so that the limiting ring 604 connected to one end of the sliding column 605 away from the disc 601 is attached to the outer surface of the stainless steel tube. If the shaking amplitude of the stainless steel tube is too large, the stainless steel tube will excessively push the limiting ring 604 to move. During the movement of the limit ring 604, the upper end of the connecting rod 606 connected to the lower end surface of the limit ring 604 will be driven to move synchronously, so that the connecting rod 606 moves from an inclined state to a vertical state. When the state of the connecting rod 606 changes, the connecting rod 606 will push the lifting block 607 connected to one end away from the limit ring 604 to slide downward in the first through groove 8, and press the button 608 connected to the bottom of the first through groove 8 to turn on the alarm light 603 to work and prompt the staff in time, which not only makes it easier for the staff to adjust the position and stability of the stainless steel pipe, but also ensures that the welding position is accurate and uniform and avoids offset. It can also avoid welding defects in the stainless steel pipe welding joint, thereby ensuring the strength and integrity of the welding joint and improving the aesthetics of the welding joint.
