Description

Technical Field

[0001] The utility model relates to the field of welding wire processing, in particular to an anti-fracture traction device for welding wire processing. Background Art

[0002] Welding wire is mainly used for metal welding. It is a consumable material specially used to connect metal or other thermoplastic materials together by heating or pressurizing to achieve the purpose of welding. According to different application scenarios and welding methods, welding wire can be divided into many types, including but not limited to stainless steel welding wire, two-protection welding wire and laser welding wire. During the welding wire processing, it is necessary to provide a traction function to ensure the efficiency of the welding wire processing.

[0003] After searching, Chinese patent announcement number: CN219771389U discloses an anti-fracture traction device for welding wire processing. A proper amount of lubricating oil is injected into the return oil shell through the oil filling pipe, and the pulling cylinder is started to push the traction plate to move in the slide groove, so that the welding wire is passed through the circular ring of the guide frame, and at the same time, the welding wire is restricted from shaking. The push rod of the double-rod cylinder will push the clamping frame to clamp the welding wire. When the traction plate is pulled to move, the lubricating oil will enter the traction tube. Under the pressure of air pressure, the traction plate will be pulled evenly when pulling, and the instantaneous force will be relieved.

[0004] In the above technical solution, a double-rod cylinder is used to clamp the welding wire, and a traction plate and a traction tube are used to prevent the welding wire from breaking during traction. However, when the double-rod cylinder clamps the welding wire, there is a risk of the welding wire breaking due to excessive force at the moment of clamping. At the same time, if the clamping force is too small, the welding wire will fall off, and the stability of the welding wire traction cannot be guaranteed. Therefore, an anti-breakage traction device for welding wire processing is proposed to solve the above problems. Utility Model Content

They are existing public technical means in this field and will not be elaborated here. The surface of the traction plate 3 is provided with an anti-fracture structure, and the anti-fracture structure includes a fixed plate 6. The fixed plate 6 is provided with two groups, and the two groups of fixed plates 6 are mirror-imaged with the central axis of the traction plate 3 as the axis of symmetry. The side wall of the fixed plate 6 is fixedly connected with an electric push rod 7, and the output end of the electric push rod 7 is fixedly connected with a movable plate 8. The number of electric push rods 7 and movable plates 8 is equal to that of the fixed plate 6. The surface of the movable plate 8 is provided with a telescopic component, and the surface of the movable plate 8 is provided with a buffer component.

[0032] Reference Figure 1-Figure 3 The outer wall of the fixed plate 6 is fixedly connected to the outer wall of the traction plate 3. The telescopic assembly includes a telescopic rod 11. Four groups of telescopic rods 11 are arranged on the surface of each group of movable plates 8, and the four groups of telescopic rods 11 are distributed in a rectangular array with the center point of the movable plate 8 as the symmetry axis. The outer wall of the telescopic rod 11 is sleeved with a telescopic spring 12. The end of the telescopic spring 12 away from the movable plate 8 is fixedly connected to a clamping plate 13. The clamping plate 13 is made of hard rubber. The buffer assembly includes a groove 9. The inner wall of the groove 9 is fixedly connected to a buffer airbag 10. The outer wall of the clamping plate 13 is provided with an anti-skid groove 14, and several groups of anti-skid grooves 14 are arranged, and several groups of anti-skid grooves 14 are arranged in a semicircular shape. At the same time, the edges of the anti-skid grooves 14 are rounded. The outer wall of the clamping plate 13 is fixedly connected to a magnet 2 16, and the outer wall of the movable plate 8 is fixedly connected to a magnet 15. The magnetism of magnet 15 and magnet 2 16 is mutually repulsive. The end of the telescopic rod 11 away from the clamping plate 13 is fixedly connected to the outer wall of the movable plate 8, and the anti-skid groove 14 is arranged on the side of the clamping plate 13 away from the telescopic spring 12.

[0033] Reference Figure 4The inner wall of the guide frame 4 is rotatably connected with a guide roller 17, and the inner wall of the guide frame 4 is fixedly connected with a mounting plate 19. An embedding groove 18 is provided on the surface of the guide roller 17, and the embedding groove 18 is convenient for the guide roller 17 to be embedded when providing guidance to the welding wire. The outer wall of the guide roller 17 is fixedly connected with a ratchet 20, and the surface of the mounting plate 19 is rotatably connected with a pawl 21 through a rotating shaft. The pawl 21 enables the guide roller 17 to rotate normally when it rotates toward the traction plate 3 side, and provides restriction to the ratchet 20 when it follows the guide roller 17 to rotate toward the traction plate 3 side. The outer wall of the mounting plate 19 is rotatably connected to the outer wall of the guide roller 17.

[0034] Working principle: The welding wire passes through the inside of the guide frame 4, the welding wire is in the embedded groove 18 and contacts the guide roller 17, and the two groups of electric push rods 7 control the two groups of clamping plates 13 to approach each other to clamp and fix the two sides of the welding wire, and the cylinder 2 pulls the traction plate 3 to pull the welding wire. During the traction process of the welding wire, the guide roller 17 rotates to guide the movement of the welding wire. When the welding wire is paused during the traction process, the pawl 21 limits the ratchet 20, which will not cause the welding wire to move in the opposite direction, so that the welding wire is in a static state and contacts the guide roller 17, avoiding the welding wire The welding wire is detached from the two groups of clamping plates 13 and moves during traction. At this time, the telescopic rod 11 and the telescopic spring 12 ensure the clamping force of the clamping plate 13 on the welding wire, and the air inside the buffer airbag 10, combined with the magnetic repulsion of magnet 15 and magnet 2 16, can maintain the fixing force of the clamping plate 13 on the welding wire during the movement of the welding wire. At the same time, the anti-slip groove 14 can increase the contact area between the plane of the clamping plate 13 and the cylindrical welding wire, thereby avoiding the risk of directly clamping the welding wire and causing excessive clamping force to cause it to break, thereby improving the stability of welding wire traction.
