Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to a shearing and welding machine that prevents workpiece deformation. Background Technology

[0002] A shearing and butt welding machine is a device used for welding metal materials. It mainly joins metal materials together by shearing and butt welding. It is commonly used in the manufacturing and repair industries, especially in situations where high-strength connections are required.

[0003] When a shearing butt welding machine is in operation, it typically first shears the edges of the metal material to form a shape suitable for welding. Then, it uses electric current or other heating methods to heat the metal material to a molten state. While heating, it presses the two pieces of metal material together to form a strong welded joint. However, in existing shearing butt welding machines, the metal material is easily deformed by the extrusion force during shearing, and the metal scraps generated during the shearing process also accumulate on the machine, affecting the final welded product. Therefore, we propose a shearing butt welding machine that prevents workpiece deformation. Utility Model Content

[0004] The purpose of this invention is to provide a shearing and welding machine that prevents workpiece deformation, thus achieving the effects of preventing workpiece deformation and facilitating the cleaning of metal scraps.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a shearing and welding machine for which workpieces are not easily deformed, comprising a base plate, two mounting brackets mounted on the base plate, a connecting top plate connecting the two mounting brackets, a shearing assembly and a welding assembly mounted on the connecting top plate, and a feeding assembly and a pressing assembly mounted inside the mounting brackets. The shearing assembly is provided in two sets and located on the left and right sides of the welding assembly. The base plate is equipped with a processing platform located between the two sets of feeding assemblies. The processing platform has two processing slots, and the processing platform is also equipped with fixing assemblies located on opposite sides of the two processing slots.

[0006] By adopting the above technical solution, the metal material to be sheared and welded is placed on the feeding assembly for conveying. When the metal material on both sides is simultaneously moved towards the center and placed below the shearing assembly, the shearing assembly starts to shear the edges of the metal material on both sides. Before shearing, the fixing assembly fixes the metal material on the processing platform to prevent the metal material from shifting due to the squeezing force during shearing and causing deformation. At the same time, the processing groove cooperates with the shearing assembly. During the shearing process, the shearing end of the shearing assembly extends into the processing groove, and the lower surface of the metal material is always in close contact with the processing platform, further preventing the metal material from shifting due to the squeezing force during shearing and causing deformation. At the same time, the metal scraps generated during shearing automatically fall into the processing groove and will not remain on the processing platform, realizing automatic cleaning of metal scraps and not affecting the final welded product. Then the feeding assembly continues to start until the metal material on both sides abuts against each other. Then the welding assembly starts to weld the two sheared metal materials, completing the processing of the metal material.

[0007] A further feature of this invention is that the positions of the pressing component and the feeding component correspond one-to-one.

[0008] By adopting the above technical solution, when the feeding components on the left and right sides are conveying metal materials, the two sets of pressing components can respectively hold the metal materials on the left and right sides, so that the metal materials will not shift during the conveying process.

[0009] A further feature of this invention is that the shearing assembly includes a cylinder mounted on the connecting top plate and a shearing blade connected to the output end of the cylinder, with the processing groove corresponding one-to-one with the position of the shearing blade.

[0010] By adopting the above technical solution, when the cylinder is started, it drives the shearing blade to move down to shear the metal material on the processing platform. During the shearing process of the metal material, the shearing blade can extend into the processing groove, and the lower surface of the metal material will always be in close contact with the processing platform. The processing platform supports the metal material from the bottom, preventing the metal material from shifting due to the squeezing force during the shearing process, which would cause the metal material to deform.

[0011] A further feature of this invention is that the welding assembly includes a second cylinder mounted on the connecting top plate and a welding head connected to the output end of the second cylinder, wherein the horizontal position of the welding head is located between the two processing slots.

[0012] By adopting the above technical solution, after the metal material is sheared, the feeding component continues to transport the metal material. When the metal materials transported to the left and right sides come into contact with each other, the cylinder is activated to drive the welding head to move down. Then the welding head is energized to weld the joint of the metal materials.

[0013] A further feature of this invention is that the feeding assembly includes a plurality of feeding rollers rotatably connected to the inner side of the mounting frame, a belt drivingly connecting the plurality of feeding rollers, and a motor mounted on the mounting frame and driving one of the feeding rollers to rotate.

[0014] By adopting the above technical solution, the motor starts and drives one of the feeding rollers to rotate. When one of the feeding rollers rotates, it drives multiple feeding rollers to rotate through the belt, thus conveying the metal material to be processed.

[0015] A further feature of this invention is that the feeding directions of the left and right feeding rollers are opposite, and the upper surface of the feeding rollers is at the same horizontal level as the upper surface of the processing platform.

[0016] By adopting the above technical solution, the feeding direction of the left and right feeding rollers allows the metal materials on the left and right sides to be transported from the left and right sides to the middle to the processing platform. The feeding rollers are flush with the height of the processing platform, which facilitates the transport of the metal materials from the feeding rollers to the processing platform.

[0017] A further feature of this invention is that the pressing assembly includes a support rod mounted on the mounting frame, a fixing ring mounted on the outside of the support rod, a connecting sleeve that slides up and down on the outside of the support rod, a spring connected between the fixing ring and the connecting sleeve and sleeved on the outside of the support rod, a pressing roller rotatably connected to the connecting sleeve, and a stop block mounted on the bottom of the support rod.

[0018] By adopting the above technical solution, when the feeding roller is conveying the metal material, the pressure roller relies on the force of the spring compression to continuously squeeze the metal material downward, so that the pressure rollers on the left and right sides can hold against the metal material on the left and right sides, and prevent the metal material from shifting during feeding.

[0019] A further feature of this invention is that the fixing assembly includes a U-shaped limiting rod that slides up and down on the processing platform, a rubber pad installed inside the U-shaped limiting rod, a connecting seat installed on the processing platform, and a bolt threadedly connecting the connecting seat and the U-shaped limiting rod.

[0020] A further feature of this invention is that the inner wall of the U-shaped limiting rod has multiple threaded grooves on both the front and rear sides that are compatible with the bolt.

[0021] By adopting the above technical solution, when the metal material is transported to the processing platform for shearing, the U-shaped limiting rod slides up and down on the processing platform, so that the rubber pad on the inner side of the U-shaped limiting rod clamps the metal material. Then, the U-shaped limiting rod is fixed by connecting the bolt to the threaded groove on the U-shaped limiting rod. This can fix metal materials of different thicknesses on the processing platform and prevent the metal material from shifting due to the squeezing force during the shearing process, which would cause the metal material to deform.

[0022] A further feature of this invention is that the interior of the processing platform is hollow, and a material collection box communicating with the processing groove is slidably connected inside the processing platform.

[0023] By adopting the above technical solution, it is beneficial to collect the metal scraps that fall into the processing tank into the collection box and take them out for recycling periodically, saving manpower.

[0024] The beneficial effects of this utility model are:

[0025] 1. When the metal material is conveyed to the processing platform for shearing, the U-shaped limiting rod slides up and down on the processing platform, so that the rubber pad on the inner side of the U-shaped limiting rod holds the metal material. Then, the U-shaped limiting rod is fixed by connecting the bolt to the threaded groove on the U-shaped limiting rod. This can fix metal materials of different thicknesses on the processing platform and prevent the metal material from shifting due to the squeezing force during the shearing process, which would cause the metal material to deform.

[0026] 2. By using the processing groove and the shearing assembly together, the shearing blade can extend into the processing groove during the shearing process. The lower surface of the metal material will always be in close contact with the processing platform. The processing platform supports the metal material from the bottom, preventing the metal material from shifting due to the squeezing force during the shearing process, which would cause the metal material to deform.

[0027] 3. The metal scraps generated during shearing will automatically fall into the processing tank and will not remain on the processing platform, thus achieving automatic cleaning of metal scraps. This will not affect the final welded product. The metal scraps that fall into the processing tank are eventually collected in the collection box and periodically removed for recycling, saving manpower. Attached Figure Description

[0033] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0034] Please see Figure 1-3 This utility model provides a shearing and welding machine that prevents workpiece deformation. It includes a base plate 1, two mounting brackets 2 mounted on the base plate 1, a connecting top plate 3 connecting the two mounting brackets 2, a shearing assembly and a welding assembly mounted on the connecting top plate 3, and a feeding assembly and a pressing assembly mounted inside the mounting brackets 2. The shearing assembly is provided in two sets and located on the left and right sides of the welding assembly. The base plate 1 is equipped with a processing platform 4 located between the two sets of feeding assemblies. The processing platform 4 has two processing slots 5 and a fixing assembly located on the opposite sides of the two processing slots 5.

[0035] The metal material to be sheared and welded is placed on the feeding assembly for conveying. When the metal material on both sides is simultaneously moved towards the center onto the processing platform 4 and positioned below the shearing assembly, the shearing assembly starts to shear the edges of the metal material on both sides. Before shearing, the fixing assembly fixes the metal material on the processing platform 4 to prevent the metal material from shifting due to the squeezing force during shearing and causing deformation. At the same time, the processing groove 5 cooperates with the shearing assembly. During the shearing process, the shearing end of the shearing assembly extends into the processing groove 5, and the lower surface of the metal material remains in close contact with the processing platform 4. This further prevents the metal material from shifting due to the squeezing force during shearing and causing deformation. Meanwhile, the metal scraps generated during shearing automatically fall into the processing groove 5 and do not remain on the processing platform 4, achieving automatic cleaning of metal scraps and not affecting the final welded product. Then, the feeding assembly continues to start until the metal material on both sides abuts against each other. Then, the welding assembly starts to weld the two sheared metal materials, completing the processing of the metal material.

[0036] The pressing components and the feeding components are positioned in a one-to-one correspondence, so that when the feeding components on the left and right sides are conveying metal materials, the two sets of pressing components can respectively hold the metal materials on the left and right sides, so that the metal materials will not shift during the conveying process.

[0037] The shearing assembly includes a cylinder 6 mounted on the connecting top plate 3 and a shearing blade 7 connected to the output end of the cylinder 6. The processing groove 5 corresponds one-to-one with the position of the shearing blade 7. When the cylinder 6 is activated, it drives the shearing blade 7 to move down to shear the metal material on the processing platform 4. During the shearing process of the metal material, the shearing blade 7 can extend into the processing groove 5. The lower surface of the metal material will always be in close contact with the processing platform 4. The processing platform 4 supports the metal material from the bottom to prevent the metal material from shifting due to the squeezing force during the shearing process, which would cause the metal material to deform.

[0038] The welding assembly includes a second cylinder 8 mounted on the connecting top plate 3 and a welding head 9 connected to the output end of the second cylinder 8. The horizontal position of the welding head 9 is located between the two processing grooves 5. After the metal material is sheared, the feeding assembly continues to transport the metal material. When the metal materials transported to the left and right sides abut against each other, the cylinder 8 is activated to drive the welding head 9 to move down. Then the welding head 9 is energized to weld the joint of the metal materials.

[0039] The feeding assembly includes a plurality of feeding rollers 10 rotatably connected to the inner side of the mounting frame 2, a belt 11 driving the plurality of feeding rollers 10, and a motor 12 mounted on the mounting frame 2 and driving one of the feeding rollers 10 to rotate. When the motor 12 starts, it drives one of the feeding rollers 10 to rotate. When one of the feeding rollers 10 rotates, it drives the plurality of feeding rollers 10 to rotate through the belt 11, thereby conveying the metal material to be processed.

[0040] To improve the stability of the multiple feeding rollers 10 driven by the belt 11, internal teeth can be provided on the inner side of the belt 11, and tooth grooves adapted to the internal teeth can be provided on the feeding rollers 10 to ensure that the multiple feeding rollers 10 can maintain stable synchronous rotation and convey metal materials.

[0041] The feeding directions of the left and right feeding rollers 10 are opposite. The upper surface of the feeding rollers 10 is at the same height as the upper surface of the processing platform 4. The feeding directions of the left and right feeding rollers 10 allow the metal material on the left and right sides to be transported from the left and right sides to the middle onto the processing platform 4. The height of the feeding rollers 10 and the processing platform 4 is flush, which facilitates the transport of the metal material from the feeding rollers 10 to the processing platform 4.

[0042] The pressing assembly includes a support rod 13 mounted on the mounting frame 2, a fixing ring 14 mounted on the outside of the support rod 13, a connecting sleeve 15 that slides up and down on the outside of the support rod 13, a spring 16 connected between the fixing ring 14 and the connecting sleeve 15 and sleeved on the outside of the support rod 13, a pressing roller 17 rotatably connected to the connecting sleeve 15, and a stop block 18 mounted on the bottom of the support rod 13. When the feeding roller 10 conveys the metal material, the pressing roller 17 continuously presses the metal material downward by the force of the spring 16 after compression, so that the pressing rollers 17 on the left and right sides can abut against the metal material on the left and right sides, preventing the metal material from shifting during feeding.

[0043] The fixing assembly includes a U-shaped limiting rod 19 that slides up and down on the processing platform 4, a rubber pad 20 installed on the inner side of the U-shaped limiting rod 19, a connecting seat 21 installed on the processing platform 4, and a bolt 22 that threadedly connects the connecting seat 21 and the U-shaped limiting rod 19. The inner wall of the U-shaped limiting rod 19 has multiple threaded grooves on both the front and rear sides that are adapted to the bolt 22.

[0044] When the metal material is conveyed to the processing platform 4 for shearing, the U-shaped limiting rod 19 slides up and down on the processing platform 4, so that the rubber pad 20 on the inner side of the U-shaped limiting rod 19 holds the metal material. Then, the bolt 22 is used to connect with the threaded groove on the U-shaped limiting rod 19 to fix the U-shaped limiting rod 19. This can fix metal materials of different thicknesses on the processing platform 4 and prevent the metal material from shifting due to the squeezing force during the shearing process, which would cause the metal material to deform.

[0045] The interior of the processing platform 4 is hollow, and a collection box 23 that is connected to the processing tank 5 is slidably connected inside the processing platform 4. This facilitates the collection of metal scraps that fall into the processing tank 5 into the collection box 23 for periodic removal and recycling, saving manpower.
