Description

Technical Field

[0001] This invention relates to the technical field of manifold processing, and in particular to an integrated processing equipment for shaping and welding automotive manifolds. Background Technology

[0002] The manifold is an important component of an automotive heat exchanger. The manifold includes a main manifold and branch manifolds inserted into the main manifold. During the manufacturing of the manifold, the branch manifolds are inserted into the corresponding interfaces of the main manifold at a specific angle and then welded.

[0003] Various automatic welding processes and methods for manifolds have been proposed in the prior art. For example, patent application number CN201520329991.8 proposes a manifold assembly welding fixture. In this patent, the platform of the manifold assembly welding fixture is placed on a rotating welding table, then the main manifold is erected on a support column, and then the branch manifold is inserted into the furnace tube in the main unit at a specific position and kept stationary under the action of the support block before welding begins. Since the manifold assembly welding fixture in this embodiment can replace manual operation, and the angle of the branch manifold remains basically unchanged during the welding process due to the cooperation of the support block and the support column, the manifold assembly welding fixture of this invention can improve the welding efficiency of the manifold assembly.

[0004] However, existing technology does not have the function of shaping the manifold after welding. Because the manifold wall is thin, it is easy to cause welding deformation. It also does not have the function of opening holes for branch manifolds in the main manifold. It is necessary to open holes in the main manifold in advance, which can easily lead to deviation in the opening position, resulting in poor insertion of branch manifolds and main manifolds, affecting the welding quality. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides an integrated processing equipment for shaping and welding automotive manifolds, which has concentric positioning and opening functions and welding seam shaping functions, resulting in high welding quality.

[0006] This invention discloses an integrated shaping and welding processing device for automotive manifolds, comprising a base plate, a main pipe clamping assembly, and a branch pipe clamping assembly. The main pipe clamping assembly and the branch pipe clamping assembly are mounted on the base plate. The main pipe clamping assembly clamps the main manifold, and the branch pipe clamping assembly clamps the branch manifolds. The device also includes a hole opener clamping assembly, a welding assembly, a hole opener, a hole opener blade, a support block, and a flexible shaft. The hole opener clamping assembly is mounted on the base plate and is located between the main pipe clamping assembly and the branch pipe clamping assembly. The welding assembly is mounted on the branch pipe clamping assembly and is used to weld the joint between the branch manifolds and the main manifold. The hole opener is slidably and rotatably clamped on the base plate. On the hole opener clamping assembly, the hole opener is concentrically aligned with the manifold. Multiple hole openers are evenly and retractably mounted on the end face of the hole opener facing the main manifold. The outer ends of the multiple hole openers have opening teeth on the side facing the main manifold. Multiple support blocks are evenly and retractably mounted in the middle of the hole opener. The multiple hole openers and support blocks extend and retract radially along the hole opener. A flexible shaft passes through the manifold, with one end connected to the hole opener and the other end connected to the drive mechanism. During operation, the main pipe clamping assembly clamps the main manifold, the branch pipe clamping assembly clamps the manifold, and the hole opener clamping assembly clamps the hole opener. One end of the flexible shaft passes through the manifold. The manifold is connected to the hole opener via a drive mechanism, and the other end of the flexible shaft is connected to the drive mechanism. Multiple hole openers extend beyond the outside of the hole opener, with the distance between their outer ends slightly greater than the outer diameter of the manifold. Multiple support blocks are retracted into the hole opener. The drive mechanism drives the hole opener and multiple hole openers to rotate via the flexible shaft, pushing the hole opener closer to the main manifold on the hole opener clamping assembly. This causes the opening teeth of the multiple hole openers to drill holes in the outer wall of the main manifold, ensuring the drilled holes are concentrically aligned with the manifold. After drilling, the multiple hole openers are retracted into the hole opener, and a portion of the hole opener is pushed into the main manifold along the hole opener clamping assembly. Multiple support blocks are positioned at the junction of the main manifold and the branch manifold. These support blocks extend from the opening device, and the branch pipe clamping assembly is moved to align the end of the branch manifold with the opening of the main manifold, ensuring a good insertion state. The multiple support blocks internally support the connection between the main manifold and the branch manifold. The welding assembly welds the connection, reducing welding deformation under the support of the multiple support blocks. After welding, the drive mechanism drives the opening device and the multiple support blocks to rotate via a flexible shaft, causing the support blocks to roll and shape the inner wall of the connection, improving the roundness of the weld cross-section and thus enhancing the welding quality.

[0007] Preferably, the main manifold clamping assembly includes two slide rails, a slide table, two brackets, two screws, and two pressure plates. The two slide rails are mounted parallel to each other on the base plate. The slide table is slidably mounted on the two slide rails, and the two brackets are slidably mounted on the slide table. The upper end of each bracket is provided with a U-shaped groove. The two screws are respectively rotatably screwed onto one side wall of the U-shaped groove. The two pressure plates are respectively rotatably mounted on the inner end of the two screws. The position of the slide table on the two slide rails is adjusted according to the diameter and length specifications of the main manifold. The main manifold is placed in the U-shaped groove of the two brackets. The two screws are rotated so that the two pressure plates clamp the main manifold. The structure is simple and practical.

[0008] Preferably, the manifold clamping assembly includes a second slide table, a first pusher cylinder, two clamping seats, and the second pusher cylinder. The second slide table is slidably mounted on two slide rails. One end of the first pusher cylinder is mounted on a base plate, and the piston rod of the first pusher cylinder is connected to the second slide table. The two clamping seats are slidably mounted on the second slide table, and two clamping blocks are mounted opposite each other on the upper ends of the two clamping seats. The fixed end of the second pusher cylinder is connected to one clamping seat, and the piston rod of the second pusher cylinder is connected to the other clamping seat. The second pusher cylinder retracts and pulls the two clamping seats closer together, thereby clamping the manifold with the two clamping blocks. The first pusher cylinder extends and retracts, pushing the second slide table to move along the two slide rails, thereby connecting the manifold with the main manifold. The structure is simple and practical.

[0009] Preferably, the welding assembly includes two irregularly shaped rails, a railcar, and a welding torch. The two irregularly shaped rails are symmetrically mounted on two clamps. When the clamping blocks of the two clamps hold the manifold, the two irregularly shaped rails are joined to form a complete irregularly shaped ring. The irregularly shaped ring conforms to the weld seam of the main manifold and the manifold. The railcar is mounted on the two irregularly shaped rails via multiple rail wheels. The railcar is equipped with a drive motor for the rail wheels. The welding torch is mounted on the railcar and faces the weld seam. After the manifold and the main manifold are joined, the railcar moves along the two irregularly shaped rails, driving the welding torch to automatically weld the joint. This results in high work efficiency, and because the irregularly shaped ring formed by the two irregularly shaped rails conforms to the weld seam, the welding quality is good.

[0010] Preferably, the hole opener clamping assembly includes a slide table three, two clamping seats two, two clamping plates two, and a push cylinder three. The slide table three is slidably mounted on two slide rails, and the two clamping seats two are slidably mounted on the slide table three. The upper ends of the two clamping seats two are each fitted with a clamping plate two, which are V-shaped. The two clamping plates two clamp the hole opener relative to each other. The fixed end of the push cylinder three is connected to one clamping seat two, and the piston rod of the push cylinder three is connected to the other clamping seat two. When the push cylinder three retracts, it brings the distance between the two clamping seats two closer, so that the two clamping plates two clamp the hole opener. When a part of the hole opener is pushed into the main manifold, the push cylinder three extends, increasing the distance between the two clamping seats two, so that the two clamping plates two release the hole opener. The structure is simple and has good practicality.

[0011] Preferably, it also includes multiple rollers and springs. The multiple rollers are respectively installed on the upper and lower ends of the two clamping plates. The multiple rollers roll axially to contact the outer wall of the hole opener. One end of the spring is connected to the slide plate, and the other end of the spring is connected to the base plate. The original size of the spring keeps the position of the slide plate relatively stable. The rolling action of the multiple rollers allows the hole opener to be pushed into the main manifold by the manifold while being held by the two clamping plates. When the two clamping plates release the hole opener, the tension of the spring will reset the slide plate. It has good practicality.

[0012] Preferably, the assembly also includes a first bearing, a rotating shaft, a second bearing, a first sliding groove plate, and a second sliding groove plate. The inner ring of the first bearing is fitted onto the end of the hole opener furthest from the main manifold. The outer ring of the first bearing is held by multiple rollers. The outer wall of the first bearing is the same as the outer wall of the hole opener. The rotating shaft is rotatably mounted in the hole opener via the second bearing. The rotating shaft is concentrically positioned with the hole opener and is connected to a flexible shaft for transmission. The first sliding groove plate is concentrically mounted on the rotating shaft. The first sliding groove plate has multiple inclined first sliding grooves. Multiple hole openers are slidably connected to the multiple first sliding grooves via a first sliding rod. The second sliding groove plate is concentrically mounted on the rotating shaft. The second sliding groove plate has multiple inclined second sliding grooves. The inclination direction of the second sliding grooves is opposite to that of the first sliding grooves. Multiple support blocks are slidably connected to the multiple second sliding grooves via a second sliding rod. When opening the main manifold, the flexible shaft drives the rotating shaft to rotate inside the hole opener under the action of the second bearing. The rotating shaft drives the first sliding groove plate to rotate, causing the multiple first sliding grooves to rotate. In conjunction with multiple sliding rods, multiple piercing cutters are pushed outwards from the piercing device. Simultaneously, the rotating shaft drives the sliding groove plate to rotate, causing multiple sliding grooves and sliding rods to pull multiple support blocks inwards from the piercing device. Continued rotation of the rotating shaft drives the piercing cutters to rotate, which in turn drives the piercing device to rotate, thus opening the main manifold. During welding, the flexible shaft drives the rotating shaft to reverse, causing multiple sliding grooves and sliding rods to extend multiple support blocks outwards from the piercing device, supporting the weld joint. Simultaneously, the sliding groove plate retracts the piercing cutters inwards from the piercing device. Continued reverse rotation of the rotating shaft causes the sliding groove plate to drive multiple support blocks to rotate, which in turn drives the piercing device to rotate. This allows the support blocks to compact and shape the inside of the weld. After shaping, the rotating shaft rotates until all the piercing cutters and support blocks are inside the piercing device, at which point the piercing device is pulled out from the manifold. This design offers good practicality.

[0013] Preferably, it further includes a connector, multiple spring plates, a sheath, and bearings. A polygonal protrusion is concentrically arranged at the end of the rotating shaft facing the manifold. A connector is located at the inner end of the flexible shaft, and a slot is concentrically arranged on the connector, matching the polygonal protrusion. Multiple spring plates are evenly installed on the connector, elastically clamping the protrusion. The sheath is rotatably mounted on the flexible shaft via multiple bearings. The slot of the connector engages with the protrusion of the rotating shaft, achieving a transmission connection. The clamping action of the multiple spring plates allows the flexible shaft to pull out the rotating shaft and the opening device, while facilitating disconnection. The sheath protects the flexible shaft, and the multiple bearings prevent the sheath from rotating when the flexible shaft rotates, avoiding scratching the inner wall of the manifold. This design offers good practicality.

[0014] Preferably, it also includes multiple wheel frames, multiple torsion springs, and multiple rollers. The multiple wheel frames are evenly arranged on the outside of the sheath tube. One end of each wheel frame is rotatably connected to the sheath tube. A torsion spring is installed at the connection between the wheel frame and the sheath tube. The elastic force of the torsion spring opens the wheel frame outward. The multiple rollers are respectively installed on the outer ends of the multiple wheel frames. After the flexible shaft passes through the manifold, the elastic force of the multiple torsion springs causes the outer ends of the multiple wheel frames to open outward, so that the multiple rollers roll and support the inner wall of the manifold. This ensures that the sheath tube is basically located at the axis of the manifold, preventing the sheath tube from hitting the inner wall of the manifold when the flexible shaft rotates, thus improving practicality.

[0015] Preferably, the driving mechanism includes a fourth slide, a slider, and a motor. The fourth slide is mounted on the second slide, and the slider is slidably mounted on the fourth slide. The fourth slide drives the slider to move via a lead screw, a lead screw nut, and a stepper motor assembly. The motor is mounted on the slider, and the motor housing is connected to the protective sleeve. The motor output shaft is connected to the flexible shaft drive. The motor drives the flexible shaft to rotate, while the motor housing fixes and supports the protective sleeve. The movement of the slider on the fourth slide can push the flexible shaft and the hole opener to move, thereby facilitating drilling and removing the hole opener from the manifold, which is highly practical.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: During operation, the main pipe clamping assembly clamps the main manifold, the branch pipe clamping assembly clamps the branch manifold, and the hole opener clamping assembly clamps the hole opener. One end of the flexible shaft passes through the branch manifold and is connected to the hole opener for transmission, while the other end of the flexible shaft is connected to the drive mechanism for transmission. Multiple hole openers extend outward from the outside of the hole opener, with the distance between the outer ends of the multiple hole openers slightly greater than the outer diameter of the branch manifold. Multiple support blocks are retracted into the hole opener. The drive mechanism drives the hole opener and multiple hole openers to rotate via the flexible shaft, pushing the hole opener closer to the main manifold on the hole opener clamping assembly, so that the opening teeth of the multiple hole openers make holes in the outer wall of the main manifold, making the holes concentrically aligned with the branch manifold. After the holes are made, the multiple hole openers are... The opening is retracted into the opening device, and a portion of the opening device is pushed into the main manifold along the opening device clamping assembly, so that multiple support blocks are located at the junction of the main manifold and the branch manifold. The multiple support blocks are extended out of the opening device, and the branch manifold clamping assembly is moved so that the end of the branch manifold aligns with the opening of the main manifold, ensuring a good insertion state between the branch manifold and the main manifold. The multiple support blocks internally support the connection between the main manifold and the branch manifold. The welding assembly welds the connection, reducing welding deformation under the support of the multiple support blocks. After welding, the drive mechanism drives the opening device and the multiple support blocks to rotate via a flexible shaft, causing the multiple support blocks to roll and shape the inner wall of the connection, improving the roundness of the weld cross-section, thereby improving the welding quality.

[0029] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0030] Example 1

[0031] like Figure 1 , Figure 2 and Figure 3As shown, a shaping and welding integrated processing equipment for automotive manifolds includes a base plate 1, a main pipe clamping assembly 2, and a branch pipe clamping assembly 3. The main pipe clamping assembly 2 and the branch pipe clamping assembly 3 are mounted on the base plate 1. The main pipe clamping assembly 2 clamps the main manifold, and the branch pipe clamping assembly 3 clamps the branch manifolds. It also includes a hole opener clamping assembly 4, a welding assembly 5, a hole opener 6, a hole opener 7, a support block 8, and a flexible shaft 9. The hole opener clamping assembly 4 is mounted on the base plate 1 and is located between the main pipe clamping assembly 2 and the branch pipe clamping assembly 3. The welding assembly 5 is mounted on the branch pipe clamping assembly 3. The welding assembly 5 uses... At the joint between the welding manifold and the main manifold, the hole opener 6 is slidably and rotatably clamped on the hole opener clamping assembly 4. The hole opener 6 is concentrically aligned with the manifold. Multiple hole openers 7 are uniformly and telescopically mounted on the end face of the hole opener 6 facing the main manifold. The outer ends of the multiple hole openers 7 are provided with opening teeth on the side facing the main manifold. Multiple support blocks 8 are uniformly and telescopically mounted in the middle of the hole opener 6. The multiple hole openers 7 and the multiple support blocks 8 are all radially telescopically extended and retracted along the hole opener 6. The flexible shaft 9 passes through the manifold. One end of the flexible shaft 9 is connected to the hole opener 6 for transmission, and the other end of the flexible shaft 9 is connected to the drive mechanism for transmission.

[0032] During operation, the main manifold clamping assembly 2 clamps the main manifold, the branch manifold clamping assembly 3 clamps the branch manifold, and the hole opener clamping assembly 4 clamps the hole opener 6. One end of the flexible shaft 9 passes through the branch manifold and is connected to the hole opener 6, while the other end is connected to the drive mechanism. Multiple hole openers 7 extend outward from the outside of the hole opener 6, with the distance between the outer ends of the multiple hole openers 7 slightly greater than the outer diameter of the branch manifold. Multiple support blocks 8 retract into the hole opener 6. The drive mechanism drives the hole opener 6 and the multiple hole openers 7 to rotate via the flexible shaft 9, pushing the hole opener 6 closer to the main manifold on the hole opener clamping assembly 4. This causes the opening teeth of the multiple hole openers 7 to open holes in the outer wall of the main manifold, ensuring that the opened holes are concentrically aligned with the branch manifold. After opening, the multiple hole openers 7 are retracted into the hole opener. In step 6, a portion of the hole opener 6 is pushed into the main manifold along the hole opener clamping assembly 4, so that multiple support blocks 8 are located at the junction of the main manifold and the branch manifold. The multiple support blocks 8 are extended out of the hole opener 6, and the branch manifold clamping assembly 3 is moved so that the end of the branch manifold is connected with the opening of the main manifold, so that the branch manifold and the main manifold are well inserted. The multiple support blocks 8 support the connection between the main manifold and the branch manifold from the inside. The welding assembly 5 welds the connection. With the support of the multiple support blocks 8, the welding deformation is reduced. After the welding is completed, the drive mechanism drives the hole opener 6 and the multiple support blocks 8 to rotate through the flexible shaft 9, so that the multiple support blocks 8 roll and shape the inner wall of the connection, improve the roundness of the weld cross section, and thus improve the welding quality.

[0033] Example 2

[0034] like Figure 4 , Figure 5and Figure 6 As shown, the main pipe clamping assembly 2 includes two slide rails 10, a slide table 11, two brackets 12, two screws 13, and two pressure plates 14. The two slide rails 10 are mounted parallel to each other on the base plate 1. The slide table 11 is slidably mounted on the two slide rails 10. The two brackets 12 are slidably mounted on the slide table 11. The upper end of each of the two brackets 12 is provided with a U-shaped groove. The two screws 13 are respectively rotatably screwed onto one side wall of the U-shaped groove. The two pressure plates 14 are respectively rotatably mounted on the inner ends of the two screws 13. The branch pipe clamping assembly 3 includes a slide table 2 15, a push cylinder 16, and two... The clamping seat 17 and the push cylinder 18 are slidably mounted on two slide rails 10. One end of the push cylinder 16 is mounted on the base plate 1, and the piston rod of the push cylinder 16 is connected to the slide rail 15. Two clamping seats 17 are slidably mounted on the slide rail 15, and two clamping blocks are installed opposite each other on the upper ends of the two clamping seats 17. The fixed end of the push cylinder 18 is connected to one clamping seat 17, and the piston rod of the push cylinder 18 is connected to the other clamping seat 17. The welding assembly 5 includes two irregular rails 19, a railcar 20, and a welding torch 21. The two irregular rails 19 are symmetrically mounted on the two clamping seats 17. When the clamping block of seat 17 clamps the manifold, the two irregular rails 19 are joined to form a complete irregular ring. The weld seam between the irregular ring and the main manifold and the manifold follows the shape. The railcar 20 is mounted on the two irregular rails 19 via multiple rail wheels. The railcar 20 is equipped with a drive motor for the rail wheels. The welding torch 21 is mounted on the railcar 20 and faces the weld seam. The hole opener clamping assembly 4 includes a slide table 22, two clamping seats 23, two clamping plates 24, and a push cylinder 25. The slide table 22 is slidably mounted on the two slide rails 10, and the two clamping seats 23 are slidably mounted on the two slide rails 10. On the slide table 22, clamping plates 24 are installed on the upper ends of the two clamping seats 23. The two clamping plates 24 are V-shaped and clamp the hole opener 6 relative to each other. The fixed end of the push cylinder 25 is connected to one clamping seat 23, and the piston rod of the push cylinder 25 is connected to the other clamping seat 23. It also includes multiple rollers 26 and springs 27. The multiple rollers 26 are respectively installed on the upper and lower ends of the two clamping plates 24. The multiple rollers 26 roll axially to contact the outer wall of the hole opener 6. One end of the spring 27 is connected to the slide table 22, and the other end of the spring 27 is connected to the base plate 1.

[0035] Adjust the position of slide 11 on the two slide rails 10 according to the diameter and length specifications of the main manifold. Place the main manifold in the U-shaped slots of the two brackets 12. Rotate the two screws 13 to clamp the main manifold with the two pressure plates 14. The push cylinder 25 retracts to bring the distance between the two clamping seats 23 closer, so that the two clamping plates 24 hold the hole opener 6. The original size of the spring 27 keeps the position of slide 322 relatively stable. The push cylinder 18 retracts to pull the two clamping seats 17 closer together, so that the two clamping blocks hold the manifold. After opening the hole, the push cylinder 16 extends and retracts to push slide 215 along the two slide rails 10, so that... The manifold is inserted into the main manifold. The rolling action of multiple rollers 26 allows the hole opener 6 to be pushed into the main manifold while being held by two clamping plates 24. After a part of the hole opener 6 is pushed into the main manifold, the manifold and the main manifold are connected. The push cylinder 25 extends to increase the distance between the two clamping seats 23, causing the two clamping plates 24 to release the hole opener 6. The tension of the spring 27 resets the slide table 22. The track car 20 moves along the two irregular rails 19, driving the welding gun 21 to automatically weld the butt joint. Because the irregular ring formed by the two irregular rails 19 conforms to the shape of the weld, the welding quality is good.

[0036] Example 3

[0037] like Figure 7 , Figure 8 , Figure 9 , Figures 10 to 11As shown, it also includes bearing 28, shaft 29, bearing 30, sliding plate 31, and sliding plate 32. The inner ring of bearing 28 is fitted onto the end of the orifice 6 away from the main manifold. The outer ring of bearing 28 is held by multiple rollers 26. The outer wall of bearing 28 is the same as the outer wall of orifice 6. Shaft 29 is rotatably mounted in orifice 6 via bearing 30. Shaft 29 is concentrically arranged with orifice 6 and is connected to flexible shaft 9. Sliding plate 31 is concentrically mounted on shaft 29. Multiple inclined slide grooves are provided on the shaft 21. Multiple piercing cutters 7 are slidably connected to the multiple slide grooves 1 via slide rods 1. A slide groove plate 22 is concentrically mounted on the rotating shaft 29. Multiple inclined slide grooves 22 are provided on the slide groove plate 22. The inclination direction of the slide grooves 22 is opposite to that of the slide grooves 1. Multiple support blocks 8 are slidably connected to the multiple slide grooves 2 via slide rods 2. The shaft 29 also includes a connector 33, multiple spring plates 34, a sheath tube 35, and a bearing 36. A polygonal protrusion is concentrically provided at the end of the rotating shaft 29 facing the manifold. A connector is provided at the inner end of the flexible shaft 9. 33. The connector 33 has concentrically arranged slots that match the polygonal protrusions. Multiple spring plates 34 are evenly installed on the connector 33 to elastically clamp the protrusions. The sheath tube 35 is rotatably mounted on the flexible shaft 9 via multiple bearings 36. The connector also includes multiple wheel frames 37, multiple torsion springs 38, and multiple rollers 39. The multiple wheel frames 37 are evenly arranged on the outside of the sheath tube 35. One end of each wheel frame 37 is rotatably connected to the sheath tube 35. A torsion spring is provided at the connection between the wheel frame 37 and the sheath tube 35. 38. The elastic force of the torsion spring 38 opens the wheel frame 37 outward, and multiple rollers 39 are respectively installed on the outer ends of multiple wheel frames 37; the drive mechanism includes a slide table 40, a slider 41 and a motor 42. The slide table 40 is installed on the slide table 15, and the slider 41 is slidably installed on the slide table 40. The slide table 40 drives the slider 41 to move through a lead screw, a lead screw nut and a stepper motor assembly. The motor 42 is installed on the slider 41. The housing of the motor 42 is connected to the protective sleeve 35, and the output shaft of the motor 42 is connected to the flexible shaft 9 for transmission.

[0038] After the flexible shaft 9 is inserted into the manifold, the slot of the connector 33 engages with the protrusion of the rotating shaft 29 to achieve a transmission connection. The elastic force of multiple torsion springs 38 causes the outer ends of multiple wheel frames 37 to open outward, allowing multiple rollers 39 to roll and support the inner wall of the manifold. This ensures that the sheath tube 35 is basically located at the axis of the manifold, preventing the sheath tube 35 from impacting the inner wall of the manifold when the flexible shaft 9 rotates. The sheath tube 35 protects the flexible shaft 9, and the multiple bearings 36 prevent the sheath tube 35 from impacting the manifold when the flexible shaft 9 rotates. The motor 42 drives the flexible shaft 9 to rotate, preventing the flexible shaft 9 from scratching the inner wall of the manifold. Simultaneously, the outer casing of the motor 42 provides fixed support for the sheath 35. When drilling into the main manifold, the motor 42 drives the rotating shaft 29 via the flexible shaft 9, which rotates inside the hole opener 6 under the action of the bearing 30. The rotating shaft 29 drives the sliding groove disk 31 to rotate, causing multiple sliding grooves 1 and multiple sliding rods 1 to cooperate in pushing multiple hole openers 7 outwards from the hole opener 6. Simultaneously, the rotating shaft 29 drives the sliding groove disk 32 to rotate, causing multiple sliding grooves 2 and multiple sliding rods 1 to cooperate in pushing multiple hole openers 7 outwards from the hole opener 6. The sliding rods 2 and 3 work together to pull multiple support blocks 8 into the hole opener 6. The rotating shaft 29 continues to rotate, driving multiple hole openers 7 to rotate. The rotation of the hole openers 7 drives the hole opener 6 to rotate. The slider 41 moves on the sliding table 40, pushing the flexible shaft 9 and the hole opener 6 to move, thus opening the main manifold. During welding, the flexible shaft 9 drives the rotating shaft 29 to reverse, causing multiple grooves 2 and multiple sliding rods 2 of the sliding groove plate 32 to extend multiple support blocks 8 outwards from the hole opener 6, supporting the welding area. The first grooving disc 31 retracts multiple piercing blades 7 into the piercing device 6. After welding, the rotating shaft 29 continues to rotate in the opposite direction, causing the second grooving disc 32 to drive multiple support blocks 8 to rotate and drive the piercing device 6 to rotate. This allows the multiple support blocks 8 to roll and shape the inside of the weld. After shaping, the rotating shaft 29 rotates so that the multiple piercing blades 7 and multiple support blocks 8 are all located inside the piercing device 6. The clamping action of multiple spring plates 34 allows the flexible shaft 9 to pull the rotating shaft 29 and the piercing device 6 out of the manifold, while also facilitating disconnection.

[0039] like Figures 1 to 11As shown, the present invention discloses an integrated forming and welding processing device for automotive manifolds. During operation, two pressure plates 14 and two brackets 12 clamp the main manifold. Push cylinder 2 18 retracts, driving two clamping seats 17 to clamp the branch manifold. Push cylinder 3 25 retracts, driving two clamping seats 23 and two clamping plates 24 to clamp bearing 28. One end of a flexible shaft 9 passes through the branch manifold and is connected to a rotating shaft 29. The other end of the flexible shaft 9 is connected to the output shaft of a motor 42. Then, the rotating shaft 29 rotates clockwise, extending multiple hole-opening knives 7 outwards from the outside of the hole opener 6, while simultaneously retracting multiple support blocks 8 into the hole opener 6. The motor 42 drives the hole opener 6 and multiple hole-opening knives 7 to rotate via the flexible shaft 9. A slider 41 moves on a sliding table 40, pushing the hole opener 6 closer to the main manifold, causing the opening teeth of the multiple hole-opening knives 7 to open holes in the outer wall of the main manifold. After opening, the multiple hole-opening knives 7 retract into the hole opener 6, and the slider 41... The perforator 6 is moved again, and a portion of it is pushed into the main manifold under the rolling support of multiple rollers 26, so that multiple support blocks 8 are located at the junction of the main manifold and the branch manifold. Then, the rotating shaft 29 reverses to extend multiple support blocks 8 out of the perforator 6 and retract multiple perforating cutters 7 into the perforator 6. The push cylinder 16 pushes the slide table 25 to move, so that the end of the branch manifold is connected to the opening of the main manifold, so that multiple support blocks 8 support the connection between the main manifold and the branch manifold from the inside. The track car 20 moves along the two irregular rails 19, so that the welding gun 21 welds the connection. After welding, the motor 42 drives the perforator 6 and multiple support blocks 8 to rotate in opposite directions through the flexible shaft 9, so that multiple support blocks 8 roll and shape the inner wall of the connection. The rotating shaft 29 rotates appropriately, so that multiple perforating cutters 7 and multiple support blocks 8 retract into the perforator 6, and the perforator 6 can be pulled out from the branch manifold.

[0040] The main functions achieved by this invention are:

[0041] 1. It has the function of opening holes in the main manifold, and the opening holes are concentrically aligned with the branch manifolds, so that the branch manifolds and the main manifolds are well inserted.
