Description

Technical Field

[0001] This utility model belongs to the field of welding wire processing technology, and in particular relates to a pulling mechanism for welding wire production and processing. Background Technology

[0002] Welding wire is a metal wire used in welding, either as filler metal or simultaneously as a conductive electrode. In gas welding and tungsten inert gas (TIG) welding, the welding wire serves as filler metal. In submerged arc welding, electroslag welding, and other gas metal arc welding, the welding wire acts as both filler metal and a conductive electrode. During the production and processing of welding wire, a pulling device is required to stretch the wire.

[0003] Publication No. CN219771411U discloses a wire processing pulling device. When the wire support wheel needs to be replaced, the wire support wheel that is not in contact with the welding wire extends via an electric telescopic rod, driving the connecting rod to bring the wire support wheel to the outside of the outer sleeve column. The connection of the bolt in the threaded groove is released. The user moves the wire support wheel to the welding wire position by holding the outer sleeve column with the handle, so that the wire support wheel supports the welding wire. Then the bolt is fixed to the inner and outer sleeve columns. The wire support wheel that needs to be replaced is shortened via the electric telescopic rod, bringing the wire support wheel into the groove. It can be replaced after processing is completed.

[0004] The aforementioned existing technologies still have the following drawbacks in practical implementation:

[0005] When replacing the wire guide wheel, the bolt needs to be unscrewed manually. Then, the outer sleeve post is rotated relative to the inner post by adjusting the handle, which drives the new wire guide wheel to rotate until it contacts the welding wire. After that, the bolt is screwed into the corresponding thread groove again. The process is cumbersome and inconvenient. In addition, when replacing all the wire guide wheels after processing, it is not possible to quickly remove the wire guide wheel from between the two fixing blocks and replace it with a new one, resulting in poor performance.

[0006] To address the above issues, we propose a pulling mechanism for welding wire production and processing. Utility Model Content

[0007] Technical solution

[0008] To solve the above-mentioned technical problems, this utility model provides a pulling mechanism for welding wire production and processing, including a pulling device, a wire support wheel, an adjusting column, and an outer column. The adjusting column is movably installed on the drive end surface of the pulling device, and the outer column is movably sleeved on the outside of the adjusting column. Two fixing rings are fixedly fixed on the surface of the adjusting column, respectively cooperating with the two ends of the outer column. Several grooves are formed on the surface of the outer column, and two extrusion plates are movably arranged inside the grooves. A first spring is connected between the side of the two extrusion plates that are far apart from each other and the inner wall of the groove. An electric telescopic rod is installed on the upper surface of the extrusion plate, and a clamping block is fixed at the telescopic end of the electric telescopic rod. Slots are formed on both sides of the wire support wheel, and a rotating shaft is rotatably arranged on the side of the two clamping blocks that are close to each other, cooperating with the slot. A locking mechanism is provided on the fixing rings, cooperating with the outer column. An adjusting element is provided on the surface of the outer column, cooperating with the locking mechanism.

[0009] The locking mechanism includes a movable plate, a movable rod, a positioning block, a lever plate, and a second spring. Several positioning grooves are provided on both sides of the outer column. A movable cavity is provided inside the fixed ring. The movable plate is movably disposed inside the movable cavity. Through holes and round holes are respectively provided on both sides of the inner wall of the movable cavity. The movable rod is movably engaged with the through holes, and one end of the movable rod is fixedly connected to the movable plate.

[0010] The positioning block is fixed on the side of the movable plate away from the movable rod. The positioning block cooperates with the round hole and the positioning groove. The second spring is connected between the movable plate and the inner wall of the movable cavity, and the second spring is sleeved on the outside of the movable rod. The lever plate is set on the side of the fixed ring away from the outer column, and the end of the movable rod away from the movable plate passes through the through hole and is fixedly connected to the lever plate.

[0011] The adjusting component includes a movable ring and a locking block. The movable ring is movably disposed outside the fixed ring, and the sides of the two movable rings that are close to each other are respectively fixedly connected to both ends of the outer column. The outer surface of the movable ring is provided with several locking grooves. The locking block is fixed on the side of the lever plate that is close to the outer column, and the locking block and the locking groove cooperate with each other.

[0012] Two support rods are fixed inside the groove. The two support rods are arranged opposite each other on both sides of the first spring, and the support rods pass through the extrusion plate. The extrusion plate and the support rods are slidably engaged.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This utility model utilizes the elasticity of the first spring to facilitate the compression of the two extrusion plates towards the center. Under the action of the electric telescopic rod, the two clamping blocks are driven to move closer to each other, thereby driving the two rotating shafts to be inserted into the slots on both sides of the wire support wheel. This facilitates the quick installation and removal of the wire support wheel after processing. The rotational cooperation between the rotating shaft and the clamping block facilitates the rotation of the wire support wheel, and the electric telescopic rod facilitates the adjustment of the up and down movement of the wire support wheel, ensuring the effectiveness of the wire support wheel.

[0015] Meanwhile, the elastic action of the second spring facilitates the squeezing of the movable plate away from the through hole. Combined with the movable rod and the through hole, as well as the movable block and the round hole, the positioning block is driven to pass through the round hole and insert into the corresponding positioning groove, thereby fixing the outer column between the two fixed rings. This ensures the stability of the wire support wheel during the wire pulling process and also facilitates the adjustment of the outer column relative to the adjusting column, making it easy to replace the wire support wheel.

[0016] With the cooperation of the locking block and the locking slot, as the adjusting positioning block is inserted into the corresponding positioning slot, the locking block is driven into the corresponding locking slot by the push plate. This facilitates the limiting and fixing of the movable ring, further ensuring the stability of the outer column during the wire pulling process, and thus ensuring the stability of the wire support wheel during use. At the same time, the locking slot makes it easy to move the movable ring and drive the outer column to rotate, which facilitates the replacement of the wire support wheel without the need for bolt fixing. The operation is simple and convenient. Attached Figure Description

Two fixing rings 5 ​​are fixed relative to each other on the surface of the adjusting column 3, respectively cooperating with the two ends of the outer column 4. Several grooves 7 are opened on the surface of the outer column 4. Two extrusion plates 8 are movably arranged inside the grooves 7. The side of the two extrusion plates 8 that is far apart from each other is connected to the inner wall of the groove 7 by a first spring 9. An electric telescopic rod 10 is installed on the upper surface of the extrusion plate 8. A clamping block 11 is fixed at the telescopic end of the electric telescopic rod 10. Slots are opened on both sides of the wire support wheel 2. A rotating shaft 12 is rotatably arranged on the side of the two clamping blocks 11 that is close to each other, cooperating with the slot. A locking mechanism is provided on the fixing ring 5, cooperating with the outer column 4. An adjusting component is provided on the surface of the outer column 4, cooperating with the locking mechanism.

[0025] The elastic action of the first spring 9 facilitates the compression of the two extrusion plates 8 towards the center. Under the action of the electric telescopic rod 10, the two clamping blocks 11 are driven to move closer to each other, thereby driving the two rotating shafts 12 to be inserted into the slots on both sides of the wire support wheel 2. This facilitates the quick installation, disassembly and replacement of the wire support wheel 2 after processing. The rotational cooperation between the rotating shaft 12 and the clamping block 11 facilitates the rotation of the wire support wheel 2. Combined with the electric telescopic rod 10, it is easy to adjust the up and down movement of the wire support wheel 2, ensuring the effectiveness of the wire support wheel 2.

[0026] The locking mechanism includes a movable plate 15, a movable rod 16, a positioning block 17, a lever 18, and a second spring 19. Several positioning grooves 13 are provided on both sides of the outer column 4. A movable cavity 14 is provided inside the fixed ring 5. The movable plate 15 is movably disposed inside the movable cavity 14. Through holes and round holes are respectively passed through both sides of the inner wall of the movable cavity 14. The movable rod 16 is movably engaged with the through holes, and one end of the movable rod 16 is fixedly connected to the movable plate 15. The positioning block 17 is fixed on the side of the movable plate 15 away from the movable rod 16. The positioning block 17 engages with the round holes and the positioning grooves 13. The second spring 19 is connected between the movable plate 15 and the inner wall of the movable cavity 14, and the second spring 19 is sleeved on the outside of the movable rod 16. The lever 18 is disposed on the side of the fixed ring 5 away from the outer column 4, and the end of the movable rod 16 away from the movable plate 15 passes through the through hole and is fixedly connected to the lever 18.

[0027] The elastic action of the second spring 19 facilitates the squeezing of the movable plate 15 away from the through hole. Combined with the movable engagement of the movable rod 16 with the through hole and the movable engagement of the positioning block 17 with the round hole, the positioning block 17 is driven to pass through the round hole and insert into the corresponding positioning groove 13, thereby fixing the outer column 4 between the two fixing rings 5. This ensures the stability of the wire support wheel 2 during the wire pulling process and facilitates the adjustment of the outer column 4 relative to the adjusting column 3, making it easy to replace the wire support wheel 2.

[0028] The adjusting component includes a movable ring 6 and a locking block 21. The movable ring 6 is movably disposed outside the fixed ring 5, and the sides of the two movable rings 6 that are close to each other are fixedly connected to both ends of the outer column 4. Several locking grooves 22 are opened on the outer surface of the movable ring 6. The locking block 21 is fixed on the side of the lever plate 18 close to the outer column 4. The locking block 21 and the locking groove 22 cooperate with each other. Through the cooperation of the locking block 21 and the locking groove 22, it is easy to limit and fix the movable ring 6, further ensuring the stability of the outer column 4 during the wire pulling process, thereby ensuring the stability of the wire support wheel 2 during use. Combined with the locking groove 22, it is easy to move the movable ring 6 to drive the outer column 4 to rotate, which facilitates the replacement operation of the wire support wheel 2.

[0029] Two support rods 20 are fixed inside the groove 7. The two support rods 20 are arranged opposite each other on both sides of the first spring 9 and the support rods 20 pass through the extrusion plate 8. The extrusion plate 8 slides with the support rods 20. The support rods 20 effectively limit and guide the extrusion plate 8, ensuring the stability of the extrusion plate 8 sliding left and right.

[0030] Example:

[0031] When the wire support wheel 2 needs to be replaced, the wire support wheel 2 that is not in contact with the welding wire is extended by the electric telescopic rod 10, bringing the wire support wheel 2 to the outside of the outer column 4. At the same time, the two side plates 18 are pushed outward. Under the action of the movable rod 16, the movable plate 15 is driven to squeeze the first spring 9, which in turn drives the positioning block 17 to move into the movable cavity 14 and disengage from the corresponding positioning groove 13. At the same time, under the action of the movable plate 18, the locking block 21 is driven to disengage from the corresponding locking groove 22. With the movable cooperation of the outer column 4 and the adjusting column 3, the operator drives the movable ring 6 to rotate through the locking groove 22, which in turn drives the outer column 4 to rotate relative to the adjusting column 3 until the wire support wheel 2 that has moved to the outside of the outer column 4 rotates to the position of the welding wire, so that the wire support wheel 2 supports the welding wire, and the previous wire support wheel 2 can be replaced.

[0032] Then, the lever 18 is released, and under the elastic action of the first spring 9, the movable plate 15 is pressed towards the outer column 4 until the positioning block 17 passes through the round hole and is inserted into the corresponding positioning groove 13 to fix the outer column 4. At the same time, under the action of the lever 18, the locking block 21 is moved towards the movable ring 6 until the locking block 21 is inserted into the corresponding locking groove 22 to limit and fix the movable ring 6, thereby ensuring the stability of the wire support wheel 2 in contact with the welding wire, ensuring the stability of the wire support wheel 2 during the welding wire pulling process and the use effect of the wire support wheel 2, without the need for bolts for fixing;

[0033] After the welding wire processing is completed, the clamping blocks 11 on both sides are adjusted to move away from each other. Under the action of the electric telescopic rod 10, the extrusion plate 8 is moved to press the second spring 19 along the direction of the support rod 20 until the rotating shaft 12 is driven to disengage from the wire support wheel 2. The replaced wire support wheel 2 is removed and then a new wire support wheel 2 is installed. Under the elastic action of the second spring 19, the extrusion plates 8 on both sides are pressed towards the center, thereby driving the clamping blocks 11 to move closer to the new wire support wheel 2 until the rotating shaft 12 is inserted into the slots on both sides of the new wire support wheel 2, thus completing the quick disassembly and replacement of the wire support wheel 2.

[0034] Compared with the prior art, this utility model uses the elastic action of the first spring 9, combined with the movable rod 16 and the movable plate 15, to press the positioning block 17 into the corresponding positioning groove 13. At the same time, under the action of the lever plate 18, the locking block 21 is driven into the corresponding locking groove 22, thereby achieving the purpose of fixing the outer column 4 and the adjusting column 3 together. There is no need to use bolts for fixing. This solves the problem that in the prior art, when replacing the wire support wheel 2, it is necessary to manually unscrew the bolts, then adjust the outer column relative to the inner column by holding the handle to rotate, drive the new wire support wheel 2 to rotate until it contacts the welding wire, and then adjust the bolts to screw into the corresponding thread groove again. The steps are relatively cumbersome and inconvenient to operate.

[0035] Meanwhile, under the elastic action of the second spring 19, it is easy to adjust the two clamping blocks 11 to move closer or further apart, which facilitates the quick replacement of all the wire support wheels 2 after processing. This solves the problem in the prior art that when replacing all the wire support wheels 2 after processing, it is not possible to quickly remove the wire support wheels 2 from between the two fixed blocks and replace them with new ones, resulting in poor performance.

[0036] It should be further noted that the installation structure, connection method or setting method of each component in this utility model are all common mechanical methods, and any method that can achieve its beneficial effect can be implemented.

[0037] The pulling device 1 in this utility model is prior art disclosed in the prior art document. Its specific structure, usage method and method for pulling the welding wire will not be described in detail here.

[0038] The first spring 9 and the second spring 19 are selected by those skilled in the art based on actual conditions, so that the first spring 9 and the second spring 19 have strong resistance to deformation. This ensures that a large external force is required to deform them during use, and that the first spring 9 or the second spring 19 cannot be deformed under the pulling action of the welding wire during the production and processing process. This ensures the stability of the first spring 9 and the second spring 19 during use, prevents the wire support wheel 2 from shaking and becoming unstable during use, and thus ensures the stability of the left and right position of the wire support wheel 2 during the pulling of the welding wire.

[0039] All technical features in this embodiment can be freely combined according to actual needs.
