Description

Technical Field

[0001] This invention relates to the technical field of welding wire drawing, and in particular to a drawing device for aluminum-magnesium welding wire. Background Technology

[0002] Aluminum-magnesium welding wire is a welding material made of aluminum or aluminum alloy as the base material and magnesium as the added element. It is mainly used for connecting aluminum and aluminum alloy components. Aluminum-magnesium welding wire is processed using wire drawing equipment.

[0003] In existing wire drawing equipment, a second motor drives a cam to rotate, causing the extrusion rod to move to the right along the housing and compress the spring. When the protrusion moves away, the spring drives the extrusion rod to reset, causing the extrusion rod to slide left and right along the housing. This compresses the winding roller to rotate to the right along the third shaft. When the extrusion rod resets, the attraction of a permanent magnet causes the winding roller to reset, thus causing the winding roller to move left and right. This ensures that the welding wire is evenly wound on the outer side of the winding roller, eliminating the need for frequent replacement of the winding roller. This method has the advantages of simple structure, convenient use, and good performance.

[0004] However, in the actual wire drawing process, it is necessary to manually pull one end of the aluminum-magnesium welding wire, pass the welding wire through the wire-leading structure, and then manually wind the other end of the welding wire around the wire drawing roller before the wire drawing work can be carried out. This operation is time-consuming and labor-intensive, reducing the efficiency of wire drawing work. Therefore, there is room for improvement. Summary of the Invention

A first U-shaped plate 35 is set at the top of the reciprocating plate 34. A second horizontal plate 36 is set on the inner walls of the front and rear sides of the first U-shaped plate 35. Multiple fixed posts 37 are connected to each second horizontal plate 36. A sleeve 39 is movably fitted on each fixed post 37. The end face of the fixed post 37 is square. A fourth spring 38 is fitted on the fixed post 37. The two ends of the fourth spring 38 are respectively connected to the second horizontal plate 36 and the sleeve 39. A U-shaped seat 40 is set at one end of the sleeve 39. A wire-drawing wheel 41 is set in the U-shaped seat 40.

[0038] The second moving structure includes a guide groove 42 formed on the fixed plate 33. The bottom end of the reciprocating plate 34 is slidably disposed in the guide groove 42. The reciprocating screw 43 rotates through the fixed plate 33. The bottom end of the reciprocating plate 34 is fixedly passed through the screw sleeve 46, which is sleeved on the reciprocating screw 43. Pulleys 44 are fixedly sleeved on the front end of the reciprocating screw 43 and the front end of the rotating rod 15. A belt 45 is tightly fitted between the two pulleys 44. First, the two clamping blocks 12 are pulled apart, utilizing the elastic force of the first spring 7. The two clamping blocks 12 are pushed to hold one end of the welding wire. Then, the handle 3 is used to push the vertical plate 2 and the first horizontal plate 4 to move as a whole to feed the wire. When the extrusion block 5 moves to the wire guide wheel 41, as the extrusion block 5 continues to move, the extrusion block 5 extrudes the wire guide wheel 41, pushes the wire guide wheel 41 and the sleeve 39 to move as a whole on the fixed column 37, and compresses the fourth spring 38. In this way, the welding wire can be smoothly passed between the wire guide wheels 41 and one end of the welding wire is fed to the wire drawing roller 16.

[0039] See Figures 3-9 The plug-in structure includes a slot 18 located in the middle of one side of the fixing strip 10. A plug block 17 is movably inserted into the slot 18. The plug block 17 has plug grooves 19 on both the front and rear sides. The slot walls on both the front and rear sides of the slot 18 have first inner grooves 20. A T-shaped rod 22 moves through the wall of the first inner groove 20. A plug block 21 is provided at one end of the T-shaped rod 22. The plug block 21 is semi-circular and one end is movably inserted into the plug groove 19. A second spring 23 is sleeved on the T-shaped rod 22. The two ends of the second spring 23 are respectively connected to one end of the T-shaped rod 22 and the fixing strip 10. A locking block 26 is provided on the plug block 17. A locking groove 24 is provided on the left side of the locking block 26. An inclined surface 25 is provided on the right side of the locking block 26.

[0040] The snap-fit ​​structure includes a snap-fit ​​groove 27 on the wire drawing roller 16, a through groove 28 on the upper wall of the snap-fit ​​groove 27, a second inner groove 29 on the upper wall of the through groove 28, a lifting bar 30 movably disposed in the second inner groove 29, and multiple third springs 31 connected between the lifting bar 30 and the upper wall of the second inner groove 29. A snap-fit ​​strip 32 is disposed in the middle below the lifting bar 30, extending out of the through groove 28. During the process of the pressing block 5 moving to insert the clamping block 12 and one end of the welding wire into the snap-fit ​​groove 27 on the wire drawing roller 16, the inclined surface 25 on the snap-fit ​​strip 26 above the insertion strip 11 is pressed and squeezes the snap-fit ​​strip 32. As the pressing block 5 continues to move, the snap-fit ​​strip 32 is pushed upward in the second inner groove 29 by the snap-fit ​​block 26, compressing the third springs 31. When the upper slot 24 moves to the position directly below the card strip 32, the elastic force of the third spring 31 pushes the card strip 32 into the slot 24. Then, the handle 3 pulls the first horizontal plate 4 and the pressing block 5 to move in the opposite direction. During the movement, the wall of the insertion groove 19 on the insertion block 17 presses the insertion block 21, pushing the insertion block 21 out of the insertion groove 19, so that the insertion block 17 is separated from the fixing strip 10. This can automatically fix the welding wire in the wire drawing roller 16. When the first horizontal plate 4 moves in the opposite direction to reset, the elastic force of the fourth spring 38 pushes the wire drawing wheel 41 to move and reset, so that the welding wire can pass smoothly through multiple sets of wire drawing wheels 41. During wire drawing, the wire drawing work is performed. The operation is simple and convenient.

[0041] See Figure 1 and Figure 2 The first movable structure includes a first groove 47 on the left side of the base plate 1, a through groove below the left side wall of the first groove 47, a through plate 48 moving through the through groove, a first end block 49 at the left end of the through plate 48, a second end block 51 at the right end of the through plate 48, a second U-shaped plate 50 connecting the first end block 49 and the second end block 51, the bottom end of the vertical plate 2 connecting to the right end of the second U-shaped plate 50, and an adjustment and positioning structure between the second end block 51 and the wall of the first groove 47.

[0042] The adjusting positioning structure includes a positioning rod 61 that moves through the second end block 51. A pull ring 59 is provided at the top of the positioning rod 61. Several positioning grooves 58 are formed on the lower wall of the first groove 47, arranged in an array. A fixing ring 56 is fixedly fitted onto the positioning rod 61. A fifth spring 57 is fitted onto the positioning rod 61, with its two ends connected to the fixing ring 56 and the second end block 51 respectively. The bottom end of the positioning rod 61 is inserted into the corresponding positioning groove 58. A second through rod 53 passes laterally through the second end block 51, and a first through rod 52 passes longitudinally through the second end block 51. Both ends of the first through rod 52 and the second through rod 53 are equipped with movable... The moving block 54 has a second groove 55 on the front and rear sides of the first groove 47 for sliding. The first groove 47 has a third groove 60 on the left and right sides for sliding. Before feeding the wire by moving the first horizontal plate 4 with the handle 3, the bottom end of the positioning rod 61 is pulled out from the positioning groove 58 by the pull ring 59 according to the actual position of the wire guide wheel 41. The positioning of the second end block 51 in the first groove 47 is released. Then, by moving the second end block 51 on the first through rod 52, the first horizontal plate 4 is adjusted to move to the same horizontal direction as the wire guide wheel 41. In this way, the movement of the first horizontal plate 4 can smoothly drive the welding wire through the wire guide wheel 41.

[0043] The implementation principle of the aluminum-magnesium welding wire drawing device of this invention is as follows: First, according to the actual position of the wire-drawing wheel 41, the bottom end of the positioning rod 61 is pulled out of the positioning groove 58 by the pull ring 59, and the positioning of the second end block 51 in the first groove 47 is released. Then, by moving the second end block 51 on the first through rod 52, the first horizontal plate 4 is adjusted to move to the same horizontal direction as the wire-drawing wheel 41. Next, the two clamping blocks 12 are pulled apart, and the elastic force of the first spring 7 is used to push the two clamping blocks 12 to clamp the welding wire. One end of the wire is fed through the vertical plate 2 and the first horizontal plate 4 by pushing the handle 3. When the extrusion block 5 moves to the wire guide wheel 41, as the extrusion block 5 continues to move, it squeezes the wire guide wheel 41, pushing the wire guide wheel 41 and the sleeve 39 to move together on the fixed column 37, compressing the fourth spring 38. This allows the welding wire to pass smoothly between the wire guide wheels 41 and feed one end of the welding wire to the wire drawing roller 16. Then, the extrusion block 5 continues to move to press the clamping block 12 and the wire guide wheel 41 together. As one end of the wire is inserted into the slot 27 on the drawing roller 16, the inclined surface 25 on the locking block 26 on the insertion strip 11 is pressed against the locking strip 32. As the pressing block 5 continues to move, the locking block 26 pushes the locking strip 32 upward in the second inner groove 29, compressing the third spring 31. When the slot 24 on the locking block 26 moves to directly below the locking strip 32, the elastic force of the third spring 31 pushes the locking strip 32 into the slot 24. Then, the handle 3 is used to pull the first horizontal plate 4 and the pressing block 5 to move in opposite directions as a whole. During the movement, the wall of the insertion groove 19 on the insertion block 17 presses against the insertion block 21, pushing the insertion block 21 out of the insertion groove 19, so that the insertion block 17 is separated from the fixing strip 10. This automatically fixes the welding wire in the wire drawing roller 16. When the first horizontal plate 4 moves in the reverse direction to reset, the elastic force of the fourth spring 38 is used to push the wire drawing wheel 41 to move and reset, so that the welding wire can pass smoothly through multiple sets of wire drawing wheels 41. Finally, the motor 14 is started to drive the wire drawing roller 16 to rotate, and the wire drawing work can be carried out.

[0044] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
