Description

Technical Field

[0001] This utility model belongs to the field of sheet metal processing technology, and specifically relates to a sheet metal processing welding device. Background Technology

[0002] Ultrasonic welding is a process that uses the heat generated by high-frequency mechanical vibration to join materials. Sheet metal parts can be welded by using the heat from ultrasonic friction through symmetrical bonding.

[0003] Existing sheet metal welding molds are typically placed horizontally on the platform surface. This results in a large contact area between the workpiece and the mold, lacking natural clearance. When welding is complete and material needs to be removed, the horizontally placed mold makes it difficult for users to easily remove the sheet metal workpiece, causing time and effort issues and impacting material handling efficiency. Therefore, it is necessary to design and modify the sheet metal processing and welding equipment. Utility Model Content

[0004] In response to the problems raised in the background art, this utility model studies and designs a sheet metal processing and welding device, the purpose of which is to provide a sheet metal processing and welding device that facilitates the clamping of sheet metal workpieces, saves time and effort, and improves material cutting efficiency.

[0005] The technical solution of this utility model:

[0006] A sheet metal part processing and welding device includes a body, a welding assembly mounted on the top of the body and capable of vertical lifting, a tooling mold set on the top of the body, a support plate slidably connected to the top of the body via a guide rail, brackets movably connected to both sides of the support plate via pins, a support plate fixedly connected to the side of the bracket away from the pins, the tooling mold placed on the top of the support plate, and a driving structure provided on the surface of the welding assembly, the driving structure being able to drive the support plate to tilt and swing with the tooling mold when the welding assembly rises.

[0007] Preferably, the drive structure includes an extension rod fixedly connected to the surface of the welding assembly, a shift fork fixedly connected to the outside of the bracket, the front section of the shift fork being vertical and the rear section being inclined backward, the extension rod extending to the outside of the shift fork from the side away from the welding assembly and fixedly connected to a push rod located inside the shift fork, the push rod being slidably connected to the shift fork.

[0008] Preferably, both sides of the top of the support plate are movably connected to clamping plates via pins. The side of the clamping plate away from the support plate is in contact with the surface of the tooling mold. The surface of the support plate is provided with a linkage structure, which can control the clamping plates to clamp and release the tooling mold when the support plate swings.

[0009] Preferably, the linkage structure includes upright plates fixedly connected to both sides of the support plate. A swing rod is movably connected to the outer side of the upright plate via a pin. The swing rod and the clamping plate are connected to each other via a connecting structure. The swing rod is set in an arc shape and its center coincides with the center of the pin inside the bracket. Movable blocks are fixedly connected to both sides of the top of the machine body. A pull rod located inside the swing rod is fixedly connected to the outer side of the movable block. The pull rod and the swing rod are slidably connected.

[0010] Preferably, the connection structure includes helical gears fixedly connected to the top of the clamping plate and the inner side of the rocker arm, respectively, and the helical gears mesh with each other.

[0011] Preferably, a rubber pad is fixedly connected to the inner side of the clamping plate, and the side of the rubber pad away from the clamping plate contacts the surface of the tooling mold, and the rubber pad is elastic.

[0012] The beneficial effects of this utility model are as follows: This utility model has a reasonable structure and novel design. Through the sliding connection between the guide rail and the bearing plate, combined with the pin-shaft movable structure of the bracket and the support plate, the tilting function of the tooling mold is realized. The mold posture adjustment is driven by the self-power of the lifting of the welding components, without the need for additional energy. After the mold tilts, the contact area with the workpiece is reduced, forming a natural gap, reducing the risk of adhesion, and eliminating the need for prying operations when removing parts, significantly improving material unloading efficiency. The push rod slides along the inclined surface of the rear section of the fork to generate a lateral component force, converting the vertical motion into the tilting torque of the bracket. This action conversion is precise, and the tilting angle is determined by the slope of the rear section of the fork. The structure is simple and the parameters can be customized to adapt to the demolding requirements of different molds. When the support plate tilts and swings, the linkage structure simultaneously releases the clamping plate from the mold, forming a dual demolding mechanism of tilting and loosening. During welding, the clamping plate provides a stable clamping force to avoid welding vibration. The movement causes mold offset, ensuring machining accuracy; the circular trajectory of the swing arm is coaxial with the rotation center of the support, ensuring that the movement trajectory of the swing arm and the swing of the support are strictly synchronized during the tilting of the support plate; the movable block is fixed to the machine body, causing relative sliding between the pull rod and the swing arm, accurately converting the tilting angle of the support plate into the rotation angle of the swing arm, achieving precise control of the opening and closing of the clamping plate; by converting the circular swing of the swing arm into the linear opening and closing motion of the clamping plate, the transmission ratio is constant and there is no slippage; the helical gear meshing has a self-locking characteristic, which can prevent accidental loosening in the clamping state, while the contact stress distribution of the meshing surface is uniform, extending the service life; the elastic deformation of the rubber pad can compensate for the minor unevenness of the mold surface, increasing the effective contact area; the soft material avoids scratching the mold surface, while providing sufficient static friction to prevent the mold from sliding, and the elastic reset characteristic ensures that the clamping plate maintains stable contact pressure during repeated clamping, which has high practical value.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] like Figures 1-4 As shown, a sheet metal processing and welding device includes a body 1, a welding assembly 2 installed on the top of the body 1 and capable of vertical lifting, a tooling mold 3 set on the top of the body 1, a support plate 4 slidably connected to the top of the body 1 via a guide rail, brackets 5 movably connected to both sides of the support plate 4 via pins, a support plate 6 fixedly connected to the side of the bracket 5 away from the pins, the tooling mold 3 placed on the top of the support plate 6, and a driving structure 7 provided on the surface of the welding assembly 2, the driving structure 7 being able to drive the support plate 6 to tilt and swing the tooling mold 3 when the welding assembly 2 rises.

[0020] like Figure 4 As shown, the drive structure 7 includes an extension rod 8 fixedly connected to the surface of the welding assembly 2. A shift fork 9 is fixedly connected to the outside of the bracket 5. The front section of the shift fork 9 is set to be vertical, and the rear section is set to be inclined backward. The extension rod 8 extends to the outside of the shift fork 9 from the side away from the welding assembly 2 and is fixedly connected to a push rod 10 located inside the shift fork 9. The push rod 10 is slidably connected to the shift fork 9. The push rod 10 slides along the inclined surface of the rear section of the shift fork 9 to generate a lateral component force, which converts the vertical motion into the tilting torque of the bracket 5. This action conversion is precise, and the tilting angle is determined by the slope of the rear section of the shift fork 9. The structure is simple and the parameters can be customized to adapt to the demolding requirements of different molds.

[0021] like Figure 3As shown, clamping plates 11 are movably connected to both sides of the top of the support plate 6 via pins. The side of the clamping plate 11 away from the support plate 6 contacts the surface of the tooling mold 3. A linkage structure 12 is provided on the surface of the support plate 6. The linkage structure 12 can control the clamping plate 11 to clamp and release the tooling mold 3 when the support plate 6 swings. When the support plate 6 tilts and swings, the linkage structure 12 simultaneously releases the clamping plate 11 from the mold, forming a dual demolding mechanism of tilting and loosening. During welding, the clamping plate 11 provides a stable clamping force to avoid welding vibration causing mold displacement and ensure processing accuracy.

[0022] like Figure 4 As shown, the linkage structure 12 includes upright plates 13 fixedly connected to both sides of the support plate 6. A swing rod 14 is movably connected to the outer side of the upright plate 13 via a pin. The swing rod 14 and the clamping plate 11 are connected to each other through a connecting structure. The swing rod 14 is set in an arc shape and its center is consistent with the center of the pin inside the bracket 5. Movable blocks 15 are fixedly connected to both sides of the top of the machine body 1. A pull rod 16 located inside the swing rod 14 is fixedly connected to the outer side of the movable block 15. The pull rod 16 and the swing rod 14 are slidably connected. By having the arc trajectory of the swing rod 14 coaxial with the rotation center of the bracket 5, it is ensured that the movement trajectory of the swing rod 14 is strictly synchronized with the swing of the bracket 5 during the tilting process of the support plate 6. The movable block 15 is fixed to the machine body 1 so that the pull rod 16 and the swing rod 14 slide relative to each other, accurately converting the tilt angle of the support plate 6 into the rotation angle of the swing rod 14, thereby achieving precise control of the opening and closing amount of the clamping plate 11.

[0023] like Figure 2 As shown, the connection structure includes helical gears 17 fixedly connected to the top of the clamping plate 11 and the inner side of the swing rod 14 respectively. The helical gears 17 mesh with each other and convert the arc swing of the swing rod 14 into the linear opening and closing motion of the clamping plate 11. The transmission ratio is constant and there is no slippage. The meshing of the helical gears 17 has a self-locking characteristic, which can prevent accidental loosening in the clamping state. At the same time, the contact stress distribution of the meshing surface is uniform, which extends the service life.

[0024] like Figure 4 As shown, a rubber pad 18 is fixedly connected to the inner side of the clamping plate 11. The side of the rubber pad 18 away from the clamping plate 11 contacts the surface of the tooling mold 3. The rubber pad 18 is elastic. The elastic deformation of the rubber pad 18 can compensate for the slight unevenness of the mold surface and increase the effective contact area. The soft material avoids scratching the mold surface, while providing sufficient static friction to prevent the mold from sliding. Moreover, the elastic reset characteristic ensures that the clamping plate 11 maintains stable contact pressure when clamping repeatedly.

[0025] Specific usage process: In actual use, at the start of welding, the tooling mold 3 is horizontally placed on top of the support plate 6, and the clamping plate 11 is in a closed state through the linkage structure 12. On the upright plates 13 on both sides of the support plate 6, the arc-shaped swing rod 14 meshes with the clamping plate 11 through the helical gear 17, so that the elastic rubber pad 18 on the inner side of the clamping plate 11 presses tightly against the mold surface, ensuring the stability of the mold during welding. The welding assembly 2 descends vertically to the predetermined position to perform welding operations on the sheet metal workpiece placed on the mold. After welding, the welding assembly 2 rises along the vertical guide rail. At this time, the extension rod 8 fixed on the surface of the welding assembly 2 rises accordingly, driving the push rod 10 at its end to slide along the inner cavity of the outer fork 9 of the bracket 5. The front section of the fork 9 is a vertical guide section, and the rear section is designed as a backward inclined slope. When the push rod 10 slides from the vertical section into the inclined section, the push rod 10 generates a lateral thrust on the fork 9, forcing the bracket 5 to tilt and swing outward around the pin shafts on both sides of the bearing plate 4. The tilting movement of the bracket 5 is transmitted to the support plate 6 through the pin shafts, causing it to rotate around the inner cavity of the support plate 6. The connection point tilts backward by about 15°-30°. The tooling mold 3 tilts synchronously with the support plate 6, reducing the contact area with the sheet metal workpiece and creating a natural gap between them. This tilting state reduces the adsorption force between the workpiece and the mold, creating physical conditions for subsequent removal. During the tilting process of the support plate 6, the movable block 15 fixed to the top of the machine body 1 remains stationary, and the pull rod 16 on its outer side moves relative to the arc-shaped swing rod 14. Since the center of the arc trajectory of the swing rod 14 is concentric with the pin shaft of the bracket 5, when the support plate 6 tilts, the swing rod 14 rotates around the pin shaft of the vertical plate 13, and the helical gear 17 on the inner side of the swing rod 14 rotates accordingly, driving the corresponding helical gear 17 on the top of the clamping plate 11 to rotate in the opposite direction, converting the arc swing into the outward unfolding movement of the clamping plate 11. The elastic rubber pad 18 completely separates from the mold surface, releasing the clamping constraint. The tooling mold 3 is in a tilted state and the clamping plate 11 has unfolded. The operator can easily remove the welded workpiece by vertical lifting or lateral sliding, and at the same time, it is convenient for the user to replace the tooling mold 3. This utility model achieves the tilting function of tooling mold 3 by sliding connection between guide rail and bearing plate 4, combined with the pin shaft movable structure of bracket 5 and support plate 6. The mold posture adjustment is driven by the self-power of the lifting of welding component 2, without the need for additional energy. After the mold is tilted, the contact area with the workpiece is reduced, forming a natural gap, reducing the risk of adhesion, and eliminating the need for prying operation when picking up the part, which significantly improves the material unloading efficiency.

[0026] In summary, this utility model achieves the expected results.
