Description

Technical Field

[0001] The invention relates to the technical field of welding auxiliary equipment, in particular to a tooling device for controlling welding deformation. Background Art

[0002] Welding is a processing method that achieves atomic bonding of workpieces by heating, pressurizing or both. It can connect two or more separate workpieces into a whole and is widely used in the connection of metal and non-metal materials. The principle of welding is based on local heating and melting of the welding material. When the welding material is heated to a high enough temperature, it will partially or completely melt. 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.

[0021] Working principle: After welding the workpiece after bending, the staff first places the workpiece after bending on the positioning seat of the fixed shifting mechanism, and then starts a series of subsequent processing operations before welding the workpiece; first, the fixed shifting mechanism is started, and the driving motor 2 in the positioning seat is started. The rotating shaft of the driving motor 2 drives the driving disk on the limit stabilizing seat to rotate synchronously. While the driving disk rotates, it also drives the spiral track on it to rotate synchronously. While the spiral track rotates, it also makes the spiral track rotate in the arc groove on the bottom sliding seat at the bottom of the step fixed seat. Synchronous rotation, with the rotation of the spiral track on the driving disk, the driving disk drives the step fixing seat to move synchronously toward the middle in the moving groove of the positioning seat. As the step fixing seat in the moving groove moves synchronously toward the middle, the workpiece after bending on the positioning seat is also pushed to move synchronously and approach the middle during the movement of the step fixing seat. After the step fixing seat positions the workpiece on the positioning seat at the center position on the positioning seat, the step fixing seat stops moving, thereby completing the center positioning and clamping and fixing operations of the workpiece on the positioning seat. The step fixing seat moves the workpiece product center on the positioning seat to the center of the positioning seat. After the positioning and fixing is completed, the step fixing seat stops moving in the moving groove on the positioning seat. At this time, the electromagnet seat 1 in the inner cavity is energized, thereby changing the magnetism of the electromagnet seat 1 and the electromagnet seat 2, so that the magnetism of the electromagnet seat 1 and the locking socket are the same, and the magnetism of the electromagnet seat 2 and the locking socket are opposite. Through the principle that like magnets repel each other and opposite magnets attract each other, the like repulsive force generated between the electromagnet seat 1 and the locking socket causes the locking socket in the inner cavity to slide down into the bottom cavity on the driving disk, and is adsorbed and fixed by the magnetic attraction between the electromagnet seat 2 in the bottom cavity and the locking socket, thereby After the positioning is completed, the driving disk, the positioning seat and the workpiece product thereon are locked again, thereby improving the fixing stability of the metal workpiece product during subsequent processing. After the metal workpiece product on the positioning seat is positioned and locked, the electric slide rail seat at the bottom of the moving seat is started. When the electric slide rail seat is started, it drives the moving seat, the positioning seat and the workpiece product that has been positioned and locked thereon to move on the slotted moving track, so that the metal workpiece product after its movement reaches the position of the second mounting cover on the base, thereby completing the fixing and displacement processing of the damaged workpiece product;When the workpiece after being processed by the fixed shifting mechanism reaches the position of the mounting cover 2, the stress annealing mechanism is started, and the staff controls the electric telescopic rod 1 in the top seat to start through the control equipment. The rod body on the electric telescopic rod 1 is pushed out at the same time when it is started, and then the mounting cover 2 at its bottom is driven to move down synchronously while the rod body of the electric telescopic rod 1 is pushed out, so that the mounting cover 2 after moving down can insert the metal workpiece product after being positioned and fixed on the positioning seat, and then the flamethrower on the annular air supply seat is started and sprays flames to heat and preheat the metal workpiece product fixed on the positioning seat, and at the same time, the driving motor 1 in the moving seat is started synchronously, and the driving motor 1 drives the positioning seat and the metal workpiece product on it to rotate synchronously when it is started, so as to ensure the uniformity of the metal workpiece product during the preheating process, and the stress existing in its components can also be eliminated during the heating process, thereby completing the process. Annealing and stress relief treatment of metal workpiece products before welding; after the stress annealing mechanism has finished treating the metal workpiece, the fixed shifting mechanism moves the treated metal workpiece product to the position of the connecting seat again, and then the static pressure relief mechanism is started, first the electric telescopic rod three on the top seat is started, and the rod body on the electric telescopic rod three is pushed out at the same time, and the rod body of the electric telescopic rod three is pushed out while driving the connecting seat at the bottom to move synchronously, and the connecting seat drives the adjustment fixed seat and the static pressure seat at the bottom to move downward synchronously while the connecting seat moves downward synchronously, so that the static pressure mold cavity inside the static pressure seat after the downward movement is completely fitted with the metal workpiece on the positioning seat, and after the static pressure mold cavity and the metal workpiece on the positioning seat are completely fitted, they are kept for a period of time, and the metal workpiece product on the positioning seat after annealing treatment is subjected to stress relief again by static pressure fixing, so as to complete the static pressure and stress relief treatment of the metal workpiece;After the static pressure elimination mechanism has finished processing the metal workpiece, the fixed shifting mechanism moves the processed metal workpiece product to the position of the installation cover again, and then the external processing mechanism is started. First, the delivery pump on the base is started. At the same time, the delivery pump starts and delivers the rust removal liquid in the neutral rust removal liquid tank to the liquid separation seat through the connecting pipe. After the rust removal liquid enters the liquid separation seat, it is diverted to the atomizing spray row at each position, and finally the atomizing spray row atomizes and sprays it onto the surface of the metal workpiece. At the same time, the fixed shifting mechanism also synchronously rotates the metal workpiece product on the positioning seat, so that the rust removal liquid is evenly distributed on the surface of the metal workpiece product. After the rust removal liquid is evenly distributed on the surface of the metal workpiece product, the metal workpiece is left to stand for a period of time, and the rust removal liquid on it reacts with the surface rust of the metal workpiece product. After the reaction is completed, the staff controls the device The electric telescopic rod 2 in the top seat is controlled to start. After the electric telescopic rod 2 is started, the rod body on it is pushed out. While the rod body on the electric telescopic rod 2 is pushed out, the installation cover 1 is driven to move down synchronously, so that the installation cover 1 after moving down can insert the metal workpiece product on the bottom positioning seat, and at the same time, the fluffy cotton seat and the frosted layer at the bottom of the rotating seat are in contact with the metal surface and produce corresponding deformation, and then the driving motor 3 on the support seat is started, and the rotating shaft of the driving motor 3 drives the rotating seat at the bottom of the support seat to rotate synchronously while rotating, and the rotating seat drives the fluffy cotton seat at the bottom and the frosted layer on it to rotate synchronously while rotating, and the frosted layer on the fluffy cotton seat rubs and removes the impurities generated after the neutralization reaction on the surface of the metal workpiece on the positioning seat while rotating, so as to complete the external surface treatment of the metal workpiece product before welding. ;

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

[0023] 1. The present invention adds and sets a fixed displacement mechanism to perform positioning and displacement processing on the bent metal workpiece before welding. On the one hand, the metal workpiece can be accurately aligned and the angle adjusted by fixing and center positioning, thereby preventing misalignment due to slight vibration or external force interference during subsequent welding, 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 during welding more uniform, reducing defects such as welding cracks and pores caused by uneven thermal stress.

[0024] 2. The present invention adds and sets a fixed shifting mechanism to perform positioning and shifting processing on the bent metal workpiece before welding. This operation not only eliminates the need to repeatedly adjust the position of the workpiece during welding, but also allows direct welding, greatly saving operation time. At the same time, precise center positioning and fixation can reduce the correction and finishing processes after welding, especially in batch production, which can significantly improve production efficiency and reduce production costs. Moreover, after the processing is completed, the workpiece is automatically moved to the next station for processing, thereby avoiding problems such as misalignment of the workpiece caused by manual movement and subsequent repositioning.

[0025] 3. The present invention adds and sets a stress annealing mechanism. After the center of the metal workpiece product to be processed is positioned and fixed by a fixed shifting mechanism, it is subjected to stress relief treatment by annealing. Firstly, annealing treatment can reduce the hardness of the metal workpiece, making it easier to carry out subsequent welding operations and reducing the possibility of defects such as cracks during welding. Secondly, stress relief treatment can effectively remove the residual stress generated during the bending process, prevent deformation and cracking of the workpiece due to stress concentration after welding, and improve the dimensional stability and structural strength of the workpiece. At the same time, such treatment can also improve the quality and overall reliability of the welded joint, extend the service life of the metal workpiece, and reduce maintenance costs.

[0026] 4. The present invention adds and sets a static pressure relief mechanism to perform static pressure and stress relief treatment on the metal workpiece after annealing and stress relief treatment. On the one hand, this treatment method can further make the shape of the metal workpiece more regular, ensure its dimensional accuracy, and provide a more ideal basis for subsequent welding. After bending and annealing, the workpiece may still have some slight unevenness, and static pressure can effectively improve this situation. On the other hand, performing stress relief treatment again can remove the residual and newly generated stresses during the bending and annealing process to the greatest extent, thereby avoiding defects such as cracks and deformations caused by stress concentration during welding, improving the quality of the welded joint and the stability of the overall structure, extending the service life of the metal workpiece, and reducing the maintenance and replacement costs caused by quality problems.

[0027] 5. The present invention processes the surface rust of the metal workpiece after static pressure and stress elimination by adding and setting an external processing mechanism. Firstly, removing the rust can improve the cleanliness of the welding part. A clean welding surface helps the welding materials to fuse better, form a firm welding joint, and improve the welding quality and strength. Secondly, the presence of rust may produce impurities during the welding process, affecting the appearance and uniformity of the weld. After grinding away the rust, the weld is smoother and more beautiful, and the risk of welding defects caused by impurities such as rust is reduced. In addition, removing the rust can prevent the rust from continuing to corrode the metal workpiece during subsequent use, thereby extending the service life and stability of the workpiece.

[0042] Please refer to the attached Figure 5 - Attachment Fig. 9 , a fixing and shifting mechanism, which is arranged on one side of the middle part of the top of the base 1, and is used for fixing and shifting the workpiece after the bending process;

[0043] The fixed shift mechanism includes a slot 12, a slot 12 is provided in the middle of the top of the base 1, moving tracks 13 are provided on both sides of the inner bottom of the slot 12, an electric slide rail seat 21 is arranged inside the moving track 13, the top of the electric slide rail seat 21 is fixedly connected to the moving seat 10, the top of the moving seat 10 is rotatably connected to the positioning seat 9, a driving motor 22 is provided in the middle of the inner side of the moving seat 10, and the output end of the driving motor 22 is connected to the middle of the positioning seat 9.

[0044] First, when the fixed shift mechanism is started, the drive motor 28 in the positioning seat 9 is started, and the rotating shaft of the drive motor 28 drives the drive disk 23 on the limit stabilization seat 29 to rotate synchronously. While the drive disk 23 rotates, it also drives the spiral track 27 thereon to rotate synchronously. While the spiral track 27 rotates, it also makes the spiral track 27 rotate synchronously in the arc groove 31 on the bottom sliding seat 30 at the bottom of the step fixed seat 8.

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

[0046] As the spiral track 27 on the driving disk 23 rotates, the driving disk 23 drives the step fixing seat 8 to move synchronously toward the middle in the moving groove 20 of the positioning seat 9. As the step fixing seat 8 in the moving groove 20 moves synchronously toward the middle, the workpiece after the bending process on the positioning seat 9 is also pushed synchronously to move and approach the middle thereof. After the step fixing seat 8 positions the workpiece on the positioning seat 9 at the center position on the positioning seat 9, the step fixing seat 8 stops moving, thereby completing the center positioning and clamping and fixing operations of the workpiece on the positioning seat 9.

At the same time as the delivery pump 41 is started, the rust removing liquid in the neutral rust removing liquid tank 16 is delivered to the liquid separation seat 5 through the connecting pipe. After the rust removing liquid enters the liquid separation seat 5, it is diverted to the atomizing spray row 6 at each position, and finally the atomizing spray row 6 atomizes and sprays it on the surface of the metal workpiece. At the same time, the fixed shifting mechanism also synchronously rotates the metal workpiece product on the positioning seat 9, so that the rust removing liquid is evenly distributed on the surface of the metal workpiece product. After the rust removing liquid is evenly distributed on the surface of the metal workpiece product, the metal workpiece is left to stand for a period of time, and the rust removing liquid on it reacts with the surface rust of the metal workpiece product.

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

[0062] After the reaction is completed, the staff controls the electric telescopic rod 2 18 in the top seat 3 to start through the control device. After the electric telescopic rod 2 18 is started, the rod body on it is pushed out. While the rod body on the electric telescopic rod 2 18 is pushed out, the installation cover 1 17 is driven to move down synchronously, so that the installation cover 17 after moving down can insert the metal workpiece product on the bottom positioning seat 9, and at the same time, the fluffy cotton seat 39 and the frosted layer 40 at the bottom of the rotating seat 36 are in contact with the metal surface and produce corresponding deformation.

[0063] Then the driving motor three 37 on the support seat 38 is started, and the rotating shaft of the driving motor three 37 drives the rotating seat 36 at the bottom of the support seat 38 to rotate synchronously while rotating, and the rotating seat 36 drives the fluffy cotton seat 39 at the bottom and the frosted layer 40 thereon to rotate synchronously while rotating, and the frosted layer 40 on the fluffy cotton seat 39 rubs and removes impurities produced after the neutralization reaction on the surface of the metal workpiece on the positioning seat 9 while rotating, thereby completing the processing of the external surface of the metal workpiece product before welding.

[0064] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
