Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and in particular to a side bend correction device and a side bend correction method. Background Technology

[0002] Spot welding is a welding method that uses a cylindrical electrode to form a weld point between the contact surfaces of two overlapping workpieces. During spot welding, pressure is first applied to bring the workpieces into close contact, then current is applied, and the contact area melts under resistance heating. After cooling, a weld point is formed. Spot welding is mainly used for welding thin-plate components and stampings with a thickness of less than 4mm. However, existing spot welding stations cannot meet the requirements for bending plate ribs, requiring some plate ribs to be bent into a predetermined shape.

[0003] Therefore, there is a need for a device that can achieve a lateral bending effect and improve the stability of the connection structure between the plate ribs and the workpiece plate, in order to improve the final welding effect. Summary of the Invention

[0004] The technical problem to be solved by this invention is how the lateral bending correction device can provide a precise lateral bending force to ensure that the plate ribs can be bent according to the preset requirements, thereby improving the subsequent welding effect.

[0005] This invention discloses a side-bend correction device, which includes:

[0006] A gantry frame is used to support the plate ribs;

[0007] A side-bending assembly includes multiple side-bending units, which are spaced apart along a first preset direction on one side of the gantry. Each side-bending unit includes a lifting mechanism, a clamping mechanism, and a pressing head mechanism. The clamping mechanism is located on one side of the pressing head mechanism and is used for clamping the plate ribs. The pressing head mechanism is connected to the lifting mechanism on the other side away from the clamping mechanism and can move along a second preset direction under the drive of the lifting mechanism. The first preset direction and the second preset direction are not parallel to each other.

[0008] This side-bending correction device enables the stretching and deformation of each node of the rib plate through multiple side-bending units, thereby causing the rib plate to deform as a whole and adapt to the preset shape, thus improving the forming effect after welding. At the same time, the multiple side-bending units can be controlled independently, and the stretching of the rib plate can be industrialized by adjusting their parameters, avoiding large differences between multiple rib plate parts and improving the accuracy of the product.

[0009] Furthermore, the lifting mechanism includes a lifting electric cylinder and a support frame. The lifting electric cylinder includes a push rod and a cylinder body. The push rod moves along the second preset direction under the drive of the cylinder body. The pressure head mechanism is disposed at the free end of the push rod.

[0010] The lifting electric cylinder can be a horizontal lifting electric cylinder. As a modular product that integrates the servo motor and the lead screw, it converts the rotary motion of the servo motor into linear motion. At the same time, it transforms the best advantages of the servo motor, such as precise speed control, precise revolution control, and precise torque control, into precise speed control, precise position control, and precise thrust control, thereby achieving high-precision linear motion and ensuring the stability of each node of the plate rib.

[0011] Furthermore, the support frame includes an adjustable platform and a fixed plate, the fixed plate being slidably disposed on the adjustable platform, and the lifting electric cylinder being mounted on the fixed plate.

[0012] The height adjustment platform facilitates the adjustment of the fixed plate's height, thereby enabling the vertical adjustment of the lifting cylinder's position. This allows for the correction of lateral bends in ribs of different heights, improving the applicability and scope of use of the lateral bend correction device.

[0013] Furthermore, the pressure head mechanism includes a lower pressure plate with an internal strip-shaped through groove, the extension direction of the strip-shaped through groove being the same as the extension direction of the lower pressure plate, and the lower bottom surface of the lower pressure plate being used to abut against the upper top surface of the plate rib.

[0014] The design of the slotted groove reduces the overall weight of the lower pressure plate, improves the reliability and stability of the mating mechanism between the lower pressure plate and the rib, reduces friction and wear, increases contact stiffness and fatigue strength, reduces vibration and noise, and extends the service life of the lower pressure plate. It also helps save costs. Furthermore, the lower bottom surface of the lower pressure plate abuts against the upper top surface of the rib, ensuring that the rib and the workpiece are perpendicular, thus improving structural stability.

[0015] Specifically, the gantry includes a frame and legs arranged around the frame, with the top surface of the frame and the bottom surface of the lower pressure plate being parallel to each other.

[0016] Specifically, the clamping mechanism includes a base plate, a rotating plate, and rollers. There are two rotating plates and two rollers, and each rotating plate corresponds to one roller. The rollers are rotatably mounted on the rotating plates and can rotate along their own axes. The two rotating plates are respectively rotatably mounted on both sides of the base plate.

[0017] By squeezing the rollers on both sides of the rotating plate to keep them tangent to the plate ribs, the plate ribs can be pushed to the designated position more effectively, thereby achieving the lateral bending correction of the plate ribs.

[0018] Specifically, the pressing head mechanism further includes a snap-fit ​​block, which includes a connecting plate and side wing plates disposed on both sides of the connecting plate. The side wing plates on both sides cooperate with the connecting plate to form a receiving chamber for installing the lifting mechanism.

[0019] Furthermore, the side wing plates on both sides are provided with corresponding mounting through holes.

[0020] The present invention further discloses a method for correcting a side bend, including a workpiece installation step, a compaction step, and a side bend correction step, wherein;

[0021] The workpiece installation steps include workpiece plate conveying and workpiece plate positioning and clamping.

[0022] The compaction step includes pressing down the plate ribs so that the plate ribs are perpendicular to the workpiece plate.

[0023] The side-bend correction step includes assembling the clamping mechanism onto the pressure head mechanism, and using a lifting mechanism to drive the clamping mechanism at the front end of the pressure head mechanism to a preset position.

[0024] Furthermore, the workpiece plate is transported to a preset position via a conveyor line, and the workpiece plate is clamped by a tooling fixture.

[0025] The present invention has at least, but is not limited to, the following beneficial effects:

[0026] The side-bending correction device of this invention enables the stretching deformation of each node of the rib plate through multiple side-bending units, thereby causing the rib plate as a whole to deform and adapt to a preset shape, thus improving the forming effect after welding. At the same time, the multiple side-bending units can be controlled independently, and the stretching of the rib plate can be industrialized by adjusting their parameters, avoiding large differences between multiple rib plate parts and improving the accuracy of the product.

[0039] like Figures 1-5 As shown, this embodiment of the invention discloses a lateral bending correction device 100, which includes a gantry 10 and a lateral bending assembly. The gantry 10 is used to support the plate rib 20. The lateral bending assembly includes a plurality of lateral bending units 11, which are spaced apart on one side of the gantry 10 along a first preset direction. Each lateral bending unit 11 includes a lifting mechanism, a clamping mechanism, and a pressing head mechanism. The clamping mechanism is located on one side of the pressing head mechanism and is used to clamp the plate rib 20. The pressing head mechanism is connected to the lifting mechanism on the other side away from the clamping mechanism and can move along a second preset direction under the drive of the lifting mechanism. The first preset direction and the second preset direction are not parallel to each other.

[0040] It is worth noting that the side-bending correction device 100 can stretch and deform each node of the rib 20 through multiple side-bending units 11, thereby causing the rib 20 to deform as a whole and adapt to the preset shape, thus improving the forming effect after welding. At the same time, the multiple side-bending units 11 can be controlled independently, and the stretching of the rib 20 can be industrialized by adjusting their parameters, avoiding large differences between multiple ribs 20 and improving the accuracy of the product.

[0041] In this embodiment, the lifting mechanism includes a lifting electric cylinder 12 and a support frame 13. The lifting electric cylinder 12 includes a push rod 121 and a cylinder body 122. The push rod 121 moves along a second preset direction under the drive of the cylinder body 122. The pressure head mechanism is located at the free end of the push rod 121.

[0042] It is understandable that the lifting electric cylinder 12 can be a horizontal lifting electric cylinder 12. As a modular product that integrates the servo motor and the lead screw, it converts the rotational motion of the servo motor into linear motion. At the same time, it transforms the best advantages of the servo motor, such as precise speed control, precise revolution control, and precise torque control, into precise speed control, precise position control, and precise thrust control, thereby achieving high-precision linear motion and ensuring the stability of each node of the rib 20.

[0043] In this embodiment, the support frame 13 includes an adjustable platform 131 and a fixed plate 132. The fixed plate 132 is slidably disposed on the adjustable platform 131, and the lifting electric cylinder 12 is installed on the fixed plate 132.

[0044] Understandably, the height adjustment platform 131 facilitates the height adjustment of the fixed plate 132, thereby enabling the vertical adjustment of the lifting cylinder, which in turn satisfies the lateral bending correction of the ribs 20 at different heights, thus improving the applicability and scope of use of the lateral bending correction device 100.

[0045] In this embodiment, the pressure head mechanism includes a lower pressure plate 141 with an internal strip groove 142. The extension direction of the strip groove 142 is the same as the extension direction of the lower pressure plate 141, and the lower bottom surface of the lower pressure plate 141 is used to abut against the upper top surface of the plate rib 20.

[0046] Understandably, the design of the strip groove 142 can reduce the overall weight of the lower pressure plate 141, improve the reliability and stability of the lower pressure plate 141 in conjunction with the plate rib 20, reduce friction and wear, improve contact stiffness and fatigue strength, reduce vibration and noise, and extend the service life of the lower pressure plate 141. It also helps save costs. Furthermore, the lower bottom surface of the lower pressure plate 141 abuts against the upper top surface of the plate rib 20, ensuring that the plate rib 20 and the workpiece plate 21 are perpendicular to each other, thus improving structural stability.

[0047] In this embodiment, the gantry 10 includes a frame 101 and legs 102 arranged around the frame 101. The top surface of the frame 101 is parallel to the bottom surface of the lower pressure plate 141.

[0048] Specifically, the clamping mechanism includes a base plate 151, a rotating plate 152, and a roller 153. There are two rotating plates 152 and two rollers 153, and the rotating plates 152 and rollers 153 correspond one-to-one. The rollers 153 are rotatably mounted on the rotating plates 152 and can rotate along their own axis. The two rotating plates 152 are respectively rotatably mounted on both sides of the base plate 151.

[0049] It is worth noting that by squeezing the rollers 153 on both sides of the rotating plate 152 to keep them tangent to the rib 20, the rib 20 can be pushed to the designated position more effectively, thereby achieving the lateral bending correction of the rib 20.

[0050] Optionally, the pressing head mechanism further includes a snap-fit ​​block 143, which includes a connecting plate 1432 and side wing plates 1431 disposed on both sides of the connecting plate 1432. The side wing plates 1431 and the connecting plate 1432 cooperate with each other to form a receiving chamber for installing the lifting mechanism.

[0051] It is worth noting that the connecting plate 1432 and the side wing plate 1431 can be manufactured using a one-piece molding process. One-piece molding is primarily used in manufacturing, meaning that a part is manufactured in a single process, eliminating the need for secondary or additional processing. The entire process completes the manufacturing of a part in one step. One-piece molding and non-one-piece molding are two different manufacturing processes. The manufactured product or part is a single unit without any joints, resulting in higher quality and longer service life compared to non-one-piece molding. The one-piece molded connecting plate 1432 and side wing plate 1431 exhibit good structural stability, extending the service life of the snap-fit ​​block 143.

[0052] Specifically, the two side wing plates 1431 are provided with corresponding mounting through holes 1433.

[0053] The present invention further discloses a method for correcting a side bend, including a workpiece installation step, a compaction step, and a side bend correction step, wherein;

[0054] The workpiece installation steps include conveying the workpiece plate 21 and positioning and clamping the workpiece plate 21;

[0055] The compaction step includes pressing down the plate rib 20 so that the plate rib 20 is perpendicular to the workpiece plate 21;

[0056] The side-bend rectification steps include assembling the clamping mechanism onto the pressure head mechanism, and using a lifting mechanism to drive the clamping mechanism at the front end of the pressure head mechanism to move to a preset position.

[0057] Furthermore, the workpiece plate 21 is transported to a preset position via a conveyor line and clamped by a tooling fixture.

[0058] In summary, this invention discloses a side-bending rectification device 100, which includes a gantry 10 and a side-bending assembly. The gantry 10 supports the plate rib 20. The side-bending assembly includes multiple side-bending units 11, which are spaced apart along a first preset direction on one side of the gantry 10. Each side-bending unit 11 includes a lifting mechanism, a clamping mechanism, and a pressing head mechanism. The clamping mechanism is located on one side of the pressing head mechanism and is used to clamp the plate rib 20. The pressing head mechanism is connected to the lifting mechanism on the other side away from the clamping mechanism and can move along a second preset direction under the drive of the lifting mechanism. The first preset direction and the second preset direction are not parallel to each other. This side-bending rectification device 100 can stretch and deform each node of the plate rib 20 through the multiple side-bending units 11, thereby causing the plate rib 20 to deform as a whole, so as to adapt it to the preset shape, thereby improving the forming effect after welding. Meanwhile, multiple side bending units 11 can be controlled separately, and the industrial stretching of the plate rib 20 can be achieved by adjusting its parameters, avoiding large differences between multiple plate ribs 20 and improving the accuracy of the product.
