Description

Technical Field

[0001] This invention relates to the field of welding auxiliary equipment technology, specifically a tooling device for controlling welding deformation. Background Technology

[0002] Welding is a processing method that uses heat, pressure, or both to achieve an atomic bond between workpieces. It can join two or more separate workpieces into a single unit and is widely used for joining metallic and non-metallic materials. The principle of welding is based on localized heating and melting of the welding material. When the welding material is heated to a sufficiently high temperature, it partially or completely melts. After the liquid metal cools and solidifies, it forms a joint with another welding material. Welding methods are mainly divided into three categories: fusion welding, pressure welding, and brazing.

[0003] Before welding some workpieces, workers first need to bend them to shape them into the required form. After bending, welding is then performed. However, since there is stress inside the workpiece after bending, direct welding can easily cause unstable welding or breakage at the weld joint, thus affecting the normal use of the workpiece. Therefore, those skilled in the art have proposed a tooling device to control welding deformation to solve the above-mentioned technical problems. Summary of the Invention

[0021] Working Principle: After welding the bent workpiece, the operator first places the bent workpiece on the positioning seat of the fixed displacement mechanism. Then, a series of pre-welding processing operations can begin. First, the fixed displacement mechanism is activated, and the second drive motor inside the positioning seat starts. The shaft of the second drive motor drives the drive disc on the limit stabilizing seat to rotate synchronously. Simultaneously, the drive disc drives the spiral track on it to rotate synchronously. As the spiral track rotates, it also moves within the arc-shaped groove on the bottom sliding seat of the stepped fixed seat. Synchronous rotation: As the spiral track on the drive disc rotates, the drive disc drives the stepped fixing seat to move synchronously towards the center within the moving groove of the positioning seat. As the stepped fixing seat moves synchronously towards the center, it also synchronously pushes the bent workpiece on the positioning seat towards its center. Once the stepped fixing seat positions the workpiece at the center of the positioning seat, it stops moving, thus completing the centering and clamping operation of the workpiece on the positioning seat. After positioning and fixing, the stepped fixing seat stops moving within the moving groove on the positioning seat. At this time, the first electromagnet seat in the inner cavity is energized, thereby changing the magnetism of the first and second electromagnet seats. The first electromagnet seat and the locking socket become magnetically similar, while the second electromagnet seat and the locking socket become magnetically dissimilar. Based on the principle of like poles repelling and unlike poles attracting, the repulsive force between the first electromagnet seat and the locking socket causes the locking socket to slide down into the bottom cavity of the drive plate. There, the magnetic attraction between the second electromagnet seat and the locking socket in the bottom cavity holds the locking socket in place, thus... After positioning, the drive plate, positioning seat, and workpiece on it are locked to improve the stability of the metal workpiece during subsequent processing. After the metal workpiece on the positioning seat is positioned and locked, the electric slide rail at the bottom of the moving seat is started. At the same time, the electric slide rail moves the moving seat, positioning seat, and the locked workpiece on it along the slotted moving track, so that the moved metal workpiece reaches the position of the second mounting cover on the base, thus completing the fixing and relocation of the damaged workpiece.After the workpiece, processed by the fixed displacement mechanism, reaches the position of mounting cover two, the stress annealing mechanism is activated. The operator controls the electric telescopic rod one inside the top seat via the control equipment. Simultaneously, the rod body of electric telescopic rod one extends, driving mounting cover two at its bottom to move downwards. This allows mounting cover two to fit over the metal workpiece product positioned and fixed on the positioning seat. Then, the flame gun on the annular air supply seat is activated, spraying flames to preheat the metal workpiece product fixed on the positioning seat. Simultaneously, drive motor one inside the moving seat is activated, driving the positioning seat and metal workpiece product to rotate. This ensures uniformity of preheating and also eliminates stress within the metal workpiece components during heating, thus completing the process. Annealing and stress relief treatment of metal workpieces before welding; after the stress annealing mechanism finishes processing the metal workpiece, the fixed displacement mechanism moves the processed metal workpiece back to the position of the connecting seat. Then, the static pressure relief mechanism is activated. First, the electric telescopic rod three on the top seat is activated. At the same time as the electric telescopic rod three is activated, its rod body is pushed out. As the electric telescopic rod three is pushed out, it drives the connecting seat at its bottom to move synchronously. At the same time as the connecting seat moves down synchronously, it drives the adjusting fixed seat and the static pressure seat at its bottom to move down synchronously. This makes the static pressure mold cavity inside the lowered static pressure seat completely fit with the metal workpiece on the positioning seat. After the static pressure mold cavity and the metal workpiece on the positioning seat are completely fitted, they are held for a period of time. Through static pressure fixing, the annealed metal workpiece on the positioning seat is relieved of stress again, thus completing the static pressure and stress relief treatment of the metal workpiece.After the static pressure elimination mechanism finishes processing the metal workpiece, the fixed displacement mechanism moves the processed metal workpiece back to the position of the mounting cover. Then, the external processing mechanism is activated. First, the delivery pump on the base starts, simultaneously delivering the rust-removing liquid from the neutral rust-removing liquid tank to the distribution seat through the connecting pipe. Once the rust-removing liquid enters the distribution seat, it is distributed to the atomizing spray nozzles at various locations. Finally, the atomizing spray nozzles spray the liquid onto the surface of the metal workpiece. At the same time, the fixed displacement mechanism rotates the metal workpiece on the positioning seat, ensuring that the rust-removing liquid is evenly distributed on the surface of the metal workpiece. After the rust-removing liquid is evenly distributed on the surface of the metal workpiece, it is left to stand for a period of time to allow the rust-removing liquid to react with the rust on the surface of the metal workpiece. After the reaction is complete, the operator controls the device... The electric telescopic rod two inside the control top seat is activated. After activation, the rod of the electric telescopic rod two extends, simultaneously causing the mounting cover one to move downwards. This allows the mounting cover one to fit onto the metal workpiece product on its bottom positioning seat. At the same time, the fluffy cotton seat and abrasive layer at the bottom of the rotating seat come into contact with the metal surface and deform accordingly. Then, the drive motor three on the support base is activated. The shaft of the drive motor three rotates, simultaneously causing the rotating seat at the bottom of the support base to rotate synchronously. The rotating seat rotates, simultaneously causing the fluffy cotton seat and its abrasive layer to rotate synchronously. As the fluffy cotton seat rotates, the abrasive layer on the fluffy cotton seat rubs away the impurities generated after the neutralization reaction on the surface of the metal workpiece on the positioning seat, thus completing the surface treatment of the metal workpiece product before welding.

[0022] This invention provides a tooling device for controlling welding deformation. It has the following beneficial effects:

[0023] 1. This invention, by adding and setting a fixed displacement mechanism, performs positioning and displacement processing on the bent metal workpiece before welding. On the one hand, it can accurately align and adjust the angle of the metal workpiece through fixing and center positioning, thereby preventing misalignment due to slight vibration or external interference during subsequent welding and ensuring that the welding point is always in the correct position. On the other hand, accurate center positioning and fixing can make the heat distribution more uniform during welding, reducing defects such as welding cracks and porosity caused by uneven thermal stress.

[0024] 2. This invention, by adding and setting a fixed displacement mechanism, performs positioning and displacement processing on the bent metal workpiece before welding. This operation not only eliminates the need for repeated adjustments to the workpiece position during welding, allowing for direct welding and significantly saving operation time, but also reduces the need for correction and finishing processes after welding due to precise center positioning and fixing. Especially in mass production, this can significantly improve production efficiency and reduce production costs. Furthermore, after processing, the workpiece is automatically moved to the next workstation for further processing, thus avoiding misalignment and subsequent repositioning problems caused by manual movement of the workpiece.

[0025] 3. This invention adds and sets a stress annealing mechanism. After the center of the metal workpiece to be processed is fixed by the fixed displacement mechanism, it is subjected to stress relief treatment by annealing. First, the annealing treatment can reduce the hardness of the metal workpiece, making it easier to perform subsequent welding operations and reducing the possibility of defects such as cracks during welding. Second, the stress relief treatment can effectively remove the residual stress generated during bending, preventing the workpiece from deforming and cracking due to stress concentration after welding, improving the dimensional stability and structural strength of the workpiece. At the same time, such treatment can also improve the quality of the welded joint and the overall reliability, extend the service life of the metal workpiece, and reduce maintenance costs.

[0026] 4. This invention adds and sets a static pressure relief mechanism to perform static pressure and a second stress relief treatment on the metal workpiece after annealing and stress relief treatment. This treatment method can, on the one hand, further make the shape of the metal workpiece more regular, ensure its dimensional accuracy, and provide a more ideal foundation for subsequent welding. After bending and annealing, the workpiece may still have some slight inhomogeneities, which static pressure can effectively improve. On the other hand, the second stress relief treatment can remove the residual and newly generated stresses from the bending and annealing process to the greatest extent. This can avoid defects such as cracks and deformation caused by stress concentration during welding, improve the quality of the welded joint and the stability of the overall structure, extend the service life of the metal workpiece, and reduce the maintenance and replacement costs caused by quality problems.

[0027] 5. This invention, by adding and setting an external processing mechanism, treats the surface rust of metal workpieces after static pressure and stress relief. First, removing rust improves the cleanliness of the welding area. A clean welding surface helps the welding materials fuse better, forming a strong weld joint and improving welding quality and strength. Second, the presence of rust may generate impurities during the welding process, affecting the aesthetics and uniformity of the weld. After grinding away the rust, the weld is smoother and more aesthetically pleasing, and the risk of welding defects caused by rust and other impurities is reduced. In addition, removing rust can prevent rust from continuing to corrode the metal workpiece during subsequent use, extending the service life and stability of the workpiece.

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Please see the appendix Figure 1 - Appendix Figure 3 This invention provides a tooling device for controlling welding deformation, including a base 1, which serves as the basic component of the overall device and is used to assemble and support the fixing and shifting mechanism and its subordinate structural components; a top seat 3, which is disposed on the top of the base 1 and is used to assemble and support the stress annealing mechanism, the static pressure relief mechanism, and the external treatment mechanism and their subordinate structural components; and an electrical control box 2, which is disposed on both sides of the middle of the front end of the base 1 and is used to install and assemble the electrical equipment required by the overall device during operation.

[0042] Please see the appendix Figure 5 - Appendix Figure 9 A fixed displacement mechanism is set on one side of the top center of the base 1, and is used to fix and displace the workpiece after bending.

[0043] The fixed displacement mechanism includes a slot 12. The top center of the base 1 has a slot 12. Both sides of the bottom inner side of the slot 12 have moving rails 13. The moving rails 13 are equipped with electric slide rail seats 21. The top of the electric slide rail seats 21 is fixedly connected to a moving seat 10. The top of the moving seat 10 is rotatably connected to a positioning seat 9. The middle inner side of the moving seat 10 is equipped with a drive motor 22, and the output end of the drive motor 22 is connected to the middle of the positioning seat 9.

[0044] When the fixed displacement mechanism is started, the second drive motor 28 in the positioning seat 9 is started. The rotating shaft of the second drive motor 28 drives the drive disk 23 on the limit stabilizing seat 29 to rotate synchronously. While the drive disk 23 is rotating, it also drives the spiral track 27 on it to rotate synchronously. While the spiral track 27 is rotating, it also rotates synchronously in the arc groove 31 on the bottom sliding seat 30 at the bottom of the stepped fixed seat 8.

[0045] The fixed displacement mechanism also includes a limiting and stabilizing seat 29. The limiting and stabilizing seat 29 is fixedly connected to the inner middle of the positioning seat 9. The driving disk 23 is rotatably connected to the top middle of the limiting and stabilizing seat 29. The second driving motor 28 is fixedly connected to the inner bottom middle of the positioning seat 9. The output end of the second driving motor 28 passes through the limiting and stabilizing seat 29 and is connected to the middle of the driving disk 23. The top of the driving disk 23 is provided with a spiral track 27.

[0046] As the spiral track 27 on the drive disk 23 rotates, the drive disk 23 drives the stepped fixing seat 8 to move synchronously towards the center within the moving groove 20 of the positioning seat 9. As the stepped fixing seat 8 moves synchronously towards the center within the moving groove 20, the bent workpiece on the positioning seat 9 is also pushed synchronously towards the center during the movement of the stepped fixing seat 8. After the stepped fixing seat 8 positions the workpiece on the positioning seat 9 at the center position on the positioning seat 9, the stepped fixing seat 8 stops moving, thereby completing the center positioning and clamping and fixing operation of the workpiece on the positioning seat 9.

[0047] The fixed displacement mechanism also includes a moving groove 20. Multiple moving grooves 20 are equidistantly arranged around the top center of the positioning seat 9. Each moving groove 20 is slidably connected to a stepped fixed seat 8. Each stepped fixed seat 8 is provided with a bottom sliding seat 30 at the bottom center. Multiple arc-shaped grooves 31 are equidistantly arranged at the bottom of the bottom sliding seat 30, and the arc-shaped grooves 31 match the spiral track 27.

[0048] After the stepped fixing seat 8 has positioned and fixed the center of the workpiece on the positioning seat 9, it stops moving within the moving groove 20 on the positioning seat 9. At this time, the electromagnet seat 24 in the inner cavity 25 is energized, thereby changing the magnetism of the electromagnet seat 24 and the electromagnet seat 33. The electromagnet seat 24 and the locking socket 26 are of the same polarity, while the electromagnet seat 33 and the locking socket 26 are of opposite polarity. Based on the principle of like poles repelling and unlike poles attracting, the repulsive force between the electromagnet seat 24 and the locking socket 26 causes the locking socket 26 in the inner cavity 25 to slide down into the bottom cavity 32 on the drive plate 23. The electromagnet seat 23 in the bottom cavity 32 and the locking socket 26 are attracted and fixed by the magnetic attraction between them. This locks the drive plate 23, the positioning seat 9, and the workpiece on them after positioning, thereby improving the stability of the metal workpiece during subsequent processing.

[0049] The fixed displacement mechanism also includes an inner cavity 25. Multiple inner cavities 25 are equidistantly arranged near the edge of the upper middle part of the inner side of the positioning seat 9. An electromagnet seat 24 is provided at the top of each inner cavity 25. A locking socket 26 is slidably connected inside each inner cavity 25. Multiple bottom cavities 32 are equidistantly arranged near the edge of the top of the positioning seat 9. An electromagnet seat 33 is provided at the bottom of each bottom cavity 32.

[0050] After the metal workpiece on the positioning seat 9 is positioned and locked, the electric slide rail seat 21 at the bottom of the moving seat 10 is started. When the electric slide rail seat 21 is started, it drives the moving seat 10, the positioning seat 9 and the workpiece that has been positioned and locked to move on the moving track 13 of the slot 12, so that the metal workpiece after it has moved reaches the position of the mounting cover 19 on the base 1, thereby completing the fixing and relocation of the damaged workpiece.

[0051] Please see the appendix Figure 4 The stress annealing mechanism is located on one side of the top center of the top seat 3 and is used to anneal and relieve stress on the workpiece after it has been processed by the fixed displacement mechanism.

[0052] The stress annealing mechanism includes an electric telescopic rod 14. The electric telescopic rod 14 is provided on one side of the top center of the top seat 3. The top of the electric telescopic rod 14 is fixedly connected to the top center of the mounting cover 19. An annular air supply seat 34 is provided in the middle of the inner wall of the mounting cover 19. Multiple flame guns 35 are arranged in a circular array on the inner center of the annular air supply seat 34.

[0053] When the stress annealing mechanism is started, the operator controls the electric telescopic rod 14 inside the top seat 3 to start it through the control equipment. At the same time as the electric telescopic rod 14 is started, its rod body is pushed out. Then, at the same time as the electric telescopic rod 14 is pushed out, it drives the mounting cover 19 at its bottom to move down synchronously. This allows the mounting cover 19 to fit the metal workpiece product that has been positioned and fixed on the positioning seat 9. Then, the flame gun 35 on the annular air supply seat 34 is started and sprays flames to heat and preheat the metal workpiece product fixed on the positioning seat 9.

[0054] At the same time, the drive motor 22 inside the moving seat 10 starts synchronously. When the drive motor 22 starts, it drives the positioning seat 9 and the metal workpiece to rotate, thereby ensuring the uniformity of the metal workpiece during the preheating process. In addition, the stress in the parts of the metal workpiece can be eliminated during the heating process, thus completing the annealing and stress relief treatment of the metal workpiece before welding.

[0055] Please see the appendix Figure 10The static pressure relief mechanism is located at the top center of the top seat 3 and is used to perform static pressure and stress relief treatment on the workpiece after the stress annealing mechanism has been completed.

[0056] The static pressure elimination mechanism includes an electric telescopic rod 3 4. The electric telescopic rod 3 4 is provided on one side of the middle part of the top of the inner wall of the top seat 3. The top of the electric telescopic rod 3 4 is fixedly connected to a connecting seat 7. The bottom middle of the connecting seat 7 is fixedly connected to an adjusting fixing seat 42. The bottom middle of the adjusting fixing seat 42 is threadedly connected to a static pressure seat 15. The inner middle of the static pressure seat 15 is provided with a static pressure mold cavity 11.

[0057] When the static pressure relief mechanism is activated, the electric telescopic rod 3 4 on the top seat 3 is activated first. At the same time as the electric telescopic rod 3 4 is activated, its rod body is pushed out. As the rod body of the electric telescopic rod 3 4 is pushed out, it drives the connecting seat 7 at its bottom to move synchronously. At the same time as the connecting seat 7 moves down synchronously, it drives the adjusting and fixing seat 42 and the static pressure seat 15 at its bottom to move down synchronously. This makes the static pressure mold cavity 11 inside the static pressure seat 15 completely fit with the metal workpiece on the positioning seat 9. After the static pressure mold cavity 11 and the metal workpiece on the positioning seat 9 are completely fitted, they are held for a period of time. Through static pressure fixing, the annealed metal workpiece on the positioning seat 9 is relieved of stress again, thus completing the static pressure and stress relief treatment of the metal workpiece.

[0058] Please see the appendix Figure 11 An external processing mechanism is located on the other side of the top center of the top seat 3, and is used to perform external processing operations on the workpiece before welding after the static pressure elimination mechanism has been processed.

[0059] The external treatment mechanism includes a liquid distribution seat 5. The liquid distribution seat 5 is fixedly connected to the middle and rear side of the top of the base 1. Multiple atomizing spray nozzles 6 are equidistantly arranged on the upper front side of the liquid distribution seat 5, and the liquid inlets of the atomizing spray nozzles 6 are all connected to the interior of the liquid distribution seat 5. A neutral rust removal liquid tank 16 is provided on the middle side of the rear end of the base 1. A transfer pump 41 is fixedly connected to the upper middle side of the rear end of the base 1. The liquid inlet of the transfer pump 41 is connected to the interior of the neutral rust removal liquid tank 16 through a connecting pipe, and the liquid outlet of the transfer pump 41 is connected to the interior of the liquid distribution seat 5 through a connecting pipe.

[0060] When the external processing mechanism is activated, the delivery pump 41 on the base 1 is started first. At the same time as the delivery pump 41 is started, the rust removal liquid in the neutral rust removal liquid tank 16 is delivered to the distribution seat 5 through the connecting pipe. After the rust removal liquid enters the distribution seat 5, it is distributed to the atomizing spray nozzles 6 at various positions. Finally, the atomizing spray nozzles 6 atomize and spray it onto the surface of the metal workpiece. At the same time, the fixing and shifting mechanism also rotates the metal workpiece on the positioning seat 9, so that the surface of the metal workpiece is evenly distributed with rust removal liquid. After the surface of the metal workpiece is evenly distributed with rust removal liquid, the metal workpiece is left to stand for a period of time to allow the rust removal liquid on it to react with the rust on the surface of the metal workpiece.

[0061] The external processing mechanism also includes an electric telescopic rod 18. The electric telescopic rod 18 is located at the middle of one side of the top of the inner wall of the top seat 3. The top of the electric telescopic rod 18 is fixedly connected to the middle of the top of the mounting cover 17. The upper middle of the inner side of the mounting cover 17 is fixedly connected to a support seat 38. The middle of the bottom of the support seat 38 is rotatably connected to a rotating seat 36. The bottom of the rotating seat 36 is provided with a fluffy cotton seat 39. The outer wall of the fluffy cotton seat 39 is provided with a frosted layer 40. The middle of the top of the support seat 38 is provided with a drive motor 37, and the output end of the drive motor 37 passes through the support seat 38 and is connected to the middle of the rotating seat 36.

[0062] After the reaction is complete, the operator uses the control equipment to activate the electric telescopic rod 18 inside the top seat 3. Upon activation, the rod of the electric telescopic rod 18 extends, simultaneously causing the mounting cover 17 to move downwards. This allows the lowered mounting cover 17 to slip onto the metal workpiece on its bottom positioning seat 9, and simultaneously brings the fluffy cotton seat 39 and the frosted layer 40 at the bottom of the rotating seat 36 into contact with the metal surface, causing corresponding deformation.

[0063] Then, the drive motor 37 on the support base 38 is started. While the shaft of the drive motor 37 is rotating, it drives the rotating seat 36 at the bottom of the support base 38 to rotate synchronously. While the rotating seat 36 is rotating, it drives the fluffy cotton seat 39 at the bottom and the abrasive layer 40 on it to rotate synchronously. While the fluffy cotton seat 39 is rotating, the abrasive layer 40 on it rubs away the impurities generated after the neutralization reaction on the surface of the metal workpiece on the positioning seat 9, thereby completing the treatment of the outer surface of the metal workpiece product before welding.

[0064] Although embodiments of the invention 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 the invention, the scope of which is defined by the appended claims and their equivalents.
