Description
Technical Field
[0001] This utility model relates to the field of welding auxiliary equipment technology, and in particular to an auxiliary device for a spring steel wire butt welding machine. Background Technology
[0002] A spring steel wire butt welding machine is a specialized device for welding spring steel wires. Its working principle is based on resistance heating technology. By applying an electric current to the workpieces, heat is generated at the contact surface, melting the metal surface and forming a weld. This equipment can be divided into two types according to the welding process: resistance butt welding and flash butt welding. Resistance butt welding involves directly fusing the workpieces by resistance heating after butt welding, while flash butt welding generates an arc and molten metal through localized contact, followed by rapid pressure application to complete the welding. Spring steel wire butt welding machines are widely used in the spring manufacturing industry, featuring high welding efficiency and stable weld quality, and can meet the welding requirements of high-strength spring steel wires.
[0003] In the production and processing of spring steel wire, weld beads often form at the joint after two steel wires are welded by a welding machine, which requires grinding. Currently, this grinding process mainly relies on manual operation. Workers need to transfer the welded steel wire to the grinding equipment and then hold the steel wire to grind it. This is not only cumbersome, time-consuming and labor-intensive, but also prone to damage to the steel wire surface or safety accidents due to unstable manual positioning. At the same time, the grinding quality is difficult to guarantee, affecting product consistency and processing efficiency. Utility Model Content
[0004] One objective of this invention is to provide an auxiliary device for a spring steel wire butt welding machine. This invention addresses the problem mentioned in the background that the current grinding process mainly relies on manual operation. Workers need to transfer the welded steel wire to the grinding equipment and then hold the steel wire to grind it. This is not only cumbersome, time-consuming, and labor-intensive, but also prone to causing the grinding disc to accidentally damage the surface of the steel wire or cause safety accidents due to unstable manual positioning. At the same time, the grinding quality is difficult to guarantee, affecting product consistency and processing efficiency.
[0005] An auxiliary device for a spring steel wire butt welding machine according to an embodiment of the present invention includes: The rotating mechanism includes a support frame mounted on a welding machine. Rotating shafts are rotatably arranged on both sides of the upper part of the support frame. Rubber rollers are symmetrically fixed on the outer side of the rotating shafts. The rubber rollers are connected to the rotating shafts through a drive assembly to achieve rotation. A positioning assembly is provided at the top of the support frame and between the left and right sets of rubber rollers to support the weld bead at the joint of the spring steel wire. The downward grinding mechanism includes a cylinder fixed to one side of a support frame. A movable plate is fixedly installed at the output end of the cylinder. A pressure roller is installed on one end of the movable plate corresponding to a spring steel wire through an elastic component. Two sets of pressure rollers are symmetrically arranged. A grinding component is installed on the top of the movable plate.
[0006] Preferably, the support frame has waist-shaped grooves at both ends, and bolts are movably installed inside the waist-shaped grooves.
[0007] Preferably, the drive assembly includes a first transmission wheel fixed to the end of the shaft, and a first motor fixedly mounted on the top of the support frame. A second transmission wheel is fixedly disposed at the output end of the first motor, and a transmission belt is installed between the first transmission wheel and the second transmission wheel.
[0008] Preferably, the support frame has a tensioning pulley rotatably mounted on one end corresponding to the transmission belt, and the transmission belt is located below and to the outside of the tensioning pulley.
[0009] Preferably, the positioning component includes a lifting frame fixedly installed on the top of the support frame, the top of the lifting frame is provided with a positioning plate, and a clearance groove is formed in the middle of the positioning plate and the lifting frame.
[0010] Preferably, the elastic component includes an elastic telescopic rod fixed to the top of the movable plate, and a positioning frame is fixedly installed at the output end of the elastic telescopic rod, with the pressure roller rotatably positioned inside the positioning frame.
[0011] Preferably, the grinding assembly includes a support arm fixed to the corresponding spring steel wire of the moving plate, and a second motor fixed to the top of the moving plate. A grinding disc is rotatably arranged inside the support arm, and a transmission assembly is installed between the second motor and the grinding disc.
[0012] Preferably, the transmission assembly consists of a sprocket and a chain.
[0013] The beneficial effects of this utility model are: 1. This utility model, through its rotating mechanism and pressing grinding mechanism, effectively avoids the problems of cumbersome operation, low efficiency, and safety hazards caused by manual transfer and hand-held grinding. After the spring steel wire is welded, it is placed on the rubber roller on the support frame. At the same time, the positioning plate in the positioning component supports the weld bead at the joint of the spring steel wire through the lifting frame, ensuring that the steel wire maintains a stable position during rotation and avoids deviation. The cylinder in the pressing grinding mechanism pushes the moving plate down, so that the pressure roller presses the surface of the steel wire through the elastic component. Meanwhile, the second motor in the grinding component drives the grinding disc to rotate at high speed through the transmission component to precisely grind the weld bead. It also works with the first motor to drive the rotating shaft to rotate through the second transmission wheel, transmission belt, and first transmission wheel, thereby driving the rubber roller to rotate synchronously, so that the steel wire can automatically rotate on the rubber roller. Therefore, this mechanism, through the combination of automatic rotation and positioning, and combined with pressing grinding, not only greatly improves grinding efficiency and consistency, but also effectively avoids accidental injury and safety accidents caused by unstable positioning during manual operation, significantly improving production safety and product quality stability. 2. This utility model, through the setting of elastic components, when the cylinder of the pressing and grinding mechanism pushes the moving plate down, the elastic telescopic rod drives the positioning frame and the internal rotating pressure roller to apply flexible pressure to the surface of the steel wire. This pressure is automatically adjusted by the buffering effect of the elastic element, ensuring that the pressure roller can closely fit the surface of the steel wire without generating rigid impact. Even if there is a slight diameter deviation or uneven surface of the steel wire, it can adapt in real time and maintain a stable clamping force, avoiding the steel wire from jumping or shifting during the grinding process, thereby significantly improving the grinding quality.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0017] refer to Figures 1-4 An auxiliary device for a spring steel wire butt welding machine, comprising: The rotating mechanism 1 includes a support frame 101 mounted on a welding machine. Rotating shafts 104 are rotatably arranged on both sides of the upper part of the support frame 101. Rubber rollers 105 are symmetrically fixed on the outer side of the rotating shafts 104. The rubber rollers 105 are connected to the rotating shafts 104 through a drive assembly to achieve rotation. The drive assembly includes a first transmission wheel 106 fixed to the end of the rotating shaft 104, and a first motor 108 fixedly installed on the top of the support frame 101. A second transmission wheel 109 is fixedly provided at the output end of the first motor 108, and a transmission belt 110 is installed between the first transmission wheel 106 and the second transmission wheel 109. A positioning component 2 is provided at the top of the support frame 101 and between the two sets of rubber rollers 105 on the left and right sides. It is used to support the weld bead at the joint of the spring steel wire. The positioning component 2 includes a lifting frame 201 fixedly installed on the top of the support frame 101. A positioning plate 202 is provided at the top of the lifting frame 201. An avoidance groove 203 is provided in the middle of the positioning plate 202 and the lifting frame 201. The downward grinding mechanism 3 includes a cylinder 301 fixed to one side of the support frame 101. A movable plate 302 is fixedly installed at the output end of the cylinder 301. A pressure roller 305 is installed at one end of the movable plate 302 corresponding to the spring steel wire through an elastic component. The elastic component includes an elastic telescopic rod 303 fixed to the top of the movable plate 302. A positioning frame 304 is fixedly installed at the output end of the elastic telescopic rod 303. The pressure roller 305 is rotatably arranged inside the positioning frame 304. When the cylinder 301 of the pressing and grinding mechanism 3 pushes the moving plate 302 down, the elastic telescopic rod 303 drives the positioning frame 304 and the internal rotating pressure roller 305 to apply flexible pressure to the surface of the steel wire. This pressure is automatically adjusted by the buffering effect of the elastic element to ensure that the pressure roller 305 can fit tightly against the surface of the steel wire without generating rigid impact. Two sets of pressure rollers 305 are symmetrically arranged. A grinding assembly is installed on the top of the movable plate 302. The grinding assembly includes a support arm 306 fixed to the corresponding spring steel wire of the movable plate 302, and a second motor 309 fixed to the top of the movable plate 302. A grinding disc 307 is rotatably arranged inside the support arm 306. A transmission assembly 308 is installed between the second motor 309 and the grinding disc 307. After welding, the spring steel wire is placed on the rubber roller 105 on the support frame 101. At the same time, the positioning plate 202 in the positioning component 2 supports the weld bead at the joint of the spring steel wire through the lifting frame 201, ensuring that the steel wire maintains a stable position during rotation and avoids displacement. The cylinder 301 in the downward grinding mechanism 3 pushes the moving plate 302 downward, so that the pressure roller 305 presses the surface of the steel wire through the elastic component. At the same time, the second motor 309 in the grinding component drives the grinding disc 307 to rotate at high speed through the transmission component 308 to precisely grind the weld bead. It also works with the first motor 108 to drive the rotating shaft 104 to rotate through the second transmission wheel 109, the transmission belt 110 and the first transmission wheel 106, thereby driving the rubber roller 105 to rotate synchronously, so that the steel wire can rotate automatically on the rubber roller 105. Therefore, this mechanism combines automatic rotation and positioning, and then works with downward grinding.
[0018] Example 1: Both ends of the support frame 101 are provided with waist-shaped grooves 102. Bolts 103 are movably installed inside the waist-shaped grooves 102 for adjusting the installation position of the support frame 101 and the welding machine. A tensioning wheel 107 is rotatably installed on one end of the support frame 101 corresponding to the transmission belt 110. The transmission belt 110 is located below and outside the tensioning wheel 107. Through the adjustment of the tensioning wheel 107, the tension of the transmission belt 110 can be effectively maintained, avoiding the transmission belt 110 from loosening or slipping due to long-term use. This ensures that the power of the first motor 108 in the drive assembly is stably transmitted to the rotating shaft 104, making the rubber roller 105 rotate smoothly, improving the accuracy of steel wire positioning and rotation, and ensuring the continuity and stability of the overall grinding process.
[0019] Example 2: The transmission assembly 308 consists of a sprocket and a chain. The output end of the second motor 309 is connected to the driving sprocket, and the end of the grinding disc 307 is equipped with a driven sprocket. The two are connected by chain drive.
[0020] Working principle: First, the spring steel wire is welded and placed on the rubber roller 105 on the support frame 101. At the same time, the positioning plate 202 in the positioning assembly 2 supports the weld bead at the joint of the spring steel wire through the lifting frame 201, ensuring that the steel wire maintains a stable position during rotation and avoids displacement. Then, the cylinder 301 in the pressing and grinding mechanism 3 is activated, pushing the moving plate 302 downward. This causes the elastic telescopic rod 303 in the elastic assembly to drive the positioning frame 304 and the internal rotating pressure roller 305 to apply flexible pressure to the surface of the steel wire. This pressure is automatically adjusted by the buffering effect of the elastic element, ensuring that the pressure roller 305 is in close contact with the surface of the steel wire and does not produce excessive pressure. A rigid impact is generated, followed by the activation of the first motor 108, which drives the rotating shaft 104 to rotate via the second transmission wheel 109, the transmission belt 110, and the first transmission wheel 106. This drives the rubber roller 105 to rotate synchronously, enabling the steel wire to rotate automatically on the rubber roller 105. Finally, the second motor 309 is activated, which drives the grinding disc 307 to rotate at high speed via the transmission assembly 308, precisely grinding the weld beads. During the grinding process, the pressure rollers 305 are symmetrically arranged and work with the elastic assembly to keep the steel wire stable. The grinding disc 307 evenly removes the weld beads during the rotation of the steel wire, ultimately achieving efficient, precise, and safe grinding of the weld beads on the spring steel wire.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
