Specific embodiments

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0019] Embodiment 1: Refer to Figure 1 , Figure 2 and Figure 4 , a traction clamping assembly, which relates to the technical field of wire production, includes a base 1, a winding roller 2 is arranged on the top of the base 1, and a U-shaped frame 52 is fixed on the top of the base 1; On the upper surface of the base 1, there are two moving seats 11 sliding along the X-axis direction. The two moving seats 11 are respectively located at both ends of the winding roller 2. On the sides of the two moving seats 11 close to each other, there are respectively rotatably connected with adapter sleeves 14. On the sides of the two adapter sleeves 14 close to each other, there are hexagonal grooves 15. At both ends of the winding roller 2, there are fixed hexagonal blocks 3, and the hexagonal blocks 3 (tolerance grade H7) and the hexagonal grooves 15 (tolerance grade H8) form a clearance fit, and the fit clearance is controlled within the range of 0.05 - 0.12 mm. There are two cylinders 12 (power sources) fixedly penetrating through the U-shaped frame 52. The output shafts of the two cylinders 12 are respectively fixedly connected with the two moving seats 11, and are used to drive the two adapter sleeves 14 to move towards the middle and insert into the hexagonal blocks 3. There are respectively rotatably penetrating through the two moving seats 11 with rotating rods 13. One ends of the two rotating rods 13 close to each other are respectively fixedly connected with the two adapter sleeves 14. The other ends of the two rotating rods 13 far away from each other both penetrate through the U-shaped frame 52. Inside the U-shaped frame 52, there is a reciprocating lead screw 16 rotatably connected above the winding roller 2. Between the reciprocating lead screw 16 and the two rotating rods 13, there is a transmission connection through synchronous pulleys and synchronous belts. The synchronous belt can be an MXL type synchronous belt, with a pitch of 0.08 inches and a bandwidth of 9 mm. The synchronous pulley located on the rotating rod 13 is slidably sleeved on the outer wall of the rotating rod 13, and can achieve a lateral sliding connection through a slider and a sliding groove. There is no relative rotation between the synchronous pulley and the rotating rod 13, and the two rotate synchronously. The synchronous pulley located on the rotating rod 13 is rotatably connected with one inner wall of the U-shaped frame 52, and is used to drive the winding roller 2 to rotate to complete the winding of the welding wire.

[0020] Referring to Figure 1 and Figure 2 , a traction device for welding wire processing, including the above-mentioned traction clamping assembly, which includes a reciprocating frame 17 sliding inside the U-shaped frame 52, and is used for evenly winding the welding wire on the winding roller 2.

[0021] Referring to Figure 2 and Figure 7 , a fixed frame 26 is also fixed on the top of the base 1. On one side of the fixed frame 26, there is a rolling cylinder 56, and the rolling cylinder 56 extends into the winding roller 2. When the welding wire is wound on the outer wall of the winding roller 2, the rolling cylinder 56 can press the welding wire tightly against the outer wall of the winding roller 2 to ensure the tightness and neatness of the welding wire winding.

[0022] Referring to Figure 1 and Figure 9 , a connecting plate 43 is provided inside the U-shaped frame 52, and a blocking plate 46 is provided on one side of the connecting plate 43. After the welding wire is wound, the blocking plate 46 can fix one end of the welding wire on the outer wall of the winding roller 2 to prevent the welding wire from loosening.

[0023] Referring to Figure 2 , Figure 5 and Figure 6, to achieve uniform winding of the welding wire, a traction structure is provided in the device. This structure includes a first guide wheel 18 rotatably arranged at one end of the reciprocating frame 17, and two second sliding grooves 19 arranged at the bottom end of the reciprocating frame 17. A first spring 23 is fixed to the top inner wall of the second sliding groove 19, and two sliding blocks 20 slide in the two second sliding grooves 19 respectively. A circular groove 21 is provided at the top of the sliding block 20, and a pressure sensor 22 is fixed in the circular groove 21. The same second guide wheel 24 is rotatably connected to the side of the two sliding blocks 20 close to each other, and the bottom end of the first spring 23 abuts against the top of the pressure sensor 22. Specifically, when the welding wire passes through the first guide wheel 18 and the second guide wheel 24, the thrust exerted by the first spring 23 on the sliding block 20 can make the first guide wheel 18 and the second guide wheel 24 cooperate to tighten the welding wire, ensuring that the welding wire can be stably wound around the outer wall of the winding roller 2. At the same time, when the tension of the welding wire is too high, it will push the second guide wheel 24 upward, causing the first spring 23 to contract and increasing the thrust on the pressure sensor 22. When the pressure sensor 22 detects that the pressure reaches a certain value (the PLC controller will reduce the motor speed to 20%-65% of the rated value), the rotation speed of the reciprocating lead screw 16 can be slowed down to avoid the welding wire from being too tight and breaking. In addition, a fixed slide bar 54 is fixed in the U-shaped frame 52, and the reciprocating frame 17 is slidably sleeved on the outer wall of the fixed slide bar 54 and slidably cooperates with the spiral groove on the outer wall of the reciprocating lead screw 16. When the reciprocating lead screw 16 rotates, it can drive the reciprocating frame 17 to reciprocate, thereby driving the first guide wheel 18, the second guide wheel 24 and the guide ring 25 to reciprocate, so that the welding wire is evenly wound around the outer wall of the winding roller 2.

[0024] Refer to Figure 2 , Figure 7 and Figure 8 , to achieve the welding wire to closely adhere to the outer wall of the winding roller 2, a fitting structure is provided in the device. When the winding roller 2 rotates for winding operation, the rolling cylinder 56 can roll along with the winding of the welding wire, pressing the welding wire tightly against the outer wall of the winding roller 2. The fitting structure includes a rotating shaft 27 rotatably installed on the side of the fixed frame 26 close to the winding roller 2. On the outer wall of this rotating shaft 27, two support arms 28 are fixedly sleeved. On the sides of the two support arms 28 away from each other, torsion springs 29 are fixed, and the other ends of the two torsion springs 29 are respectively fixed to the inner wall of one side of the fixed frame 26. At the same time, the two torsion springs 29 are also sleeved on the outer wall of the rotating shaft 27. At one end of the two support arms 28, a common arc-shaped plate 55 is fixed, and a rolling cylinder 56 is rotatably installed in this arc-shaped plate 55. Under the action of the torsion spring 29, the support arms 28 and the arc-shaped plate 55 will tightly press the welding wire against the outer wall of the winding roller 2, and this fitting method of the arc-shaped plate 55 and the rolling cylinder 56 can effectively make the welding wire tightly wound on the winding roller 2, avoiding the welding wire from loosening.

[0025] Refer to Figure 2 ,Figure 7 , Figure 8 and Figure 9 , in order to fix the welding wire by the baffle 46, a positioning structure is provided in the device to drive the connecting plate 43 and the baffle 46 to move into the winding roller 2 and fix the welding wire. At the same time, the operation of the fitting structure can drive the baffle 46 to move to fix the welding wire. The positioning structure includes two U-shaped rods 34 that slide through the U-shaped frame 52. One end of each of these two U-shaped rods 34 is fixed with a pushing plate 32. Two guiding grooves 31 are provided at the top of the fixing frame 26, and these two pushing plates 32 slide in these two guiding grooves 31 respectively. A first tension spring 33 is fixed between the bottom inner wall of the guiding groove 31 and the bottom of the pushing plate 32. On one side of the fixing frame 26, two trapezoidal lifting plates 30 are slidably connected, and these two trapezoidal lifting plates 30 cooperate with the support arm 28. When the support arm 28 rotates, it will drive the trapezoidal lifting plate 30 to move upward. The pushing plate 32 is located above the trapezoidal lifting plate 30, so the upward movement of the trapezoidal lifting plate 30 will push the pushing plate 32 upward.

[0026] Referring to Figure 1 , Figure 2 , Figure 9 and Figure 10 , inside the U-shaped frame 52, a fixing plate 35 is fixed, and a hydraulic chamber is provided inside this fixing plate 35. Inside this hydraulic chamber, a first piston plate 36 is hermetically slidably connected. The other ends of the two U-shaped rods 34 extend into the fixing plate 35 and are both fixedly connected to the top of the first piston plate 36. On the side of the fixing plate 35 away from the reciprocating frame 17, a hollow column 37 is fixed. This hollow column 37 is communicated with the fixing plate 35, and the position where it is communicated with the fixing plate 35 is below the first piston plate 36. When the first piston plate 36 moves upward, it will suck the hydraulic oil in the hollow column 37 into the fixing plate 35. On the outer wall of the hollow column 37, a sleeve plate 53 is slidably sleeved. One side of this sleeve plate 53 close to the fixing plate 35 is fixed with a retaining ring 38. A second tension spring 39 is fixed between the retaining ring 38 and the fixing plate 35, and the second tension spring 39 is sleeved on the outer wall of the hollow column 37. An oil groove is provided at the bottom of the hollow column 37, and a piston rod 40 is hermetically slidably connected inside this oil groove. One side of this piston rod 40 has an inclined surface. Therefore, when the first piston plate 36 moves upward, the first piston plate 36 sucks the hydraulic oil in the hollow column 37 into the fixing plate 35, and the piston rod 40 contracts into the oil groove at the bottom of the hollow column 37 under the action of the hydraulic oil (a piston is installed at the top of the piston rod 40 and is hermetically slidably connected in the bottom oil groove of the hollow column 37). At this time, the piston rod 40 does not protrude from the hollow column 37, and thus the piston rod 40 does not contact the sleeve plate 53, thereby releasing the braking of the sleeve plate 53.

[0027] Referring to Figure 9 and Figure 10Two circular grooves 41 are provided at the top of the sleeve plate 53, and the bottom inner walls of the two circular grooves 41 are sealed and slidably connected with a lifting rod 42. The bottom ends of the two lifting rods 42 are fixedly connected to the top of a connecting plate 43. Two baffles 44 are fixed on the side of the connecting plate 43 close to the winding roller 2, which are used to place the blocking plate 46. At the same time, a plurality of magnets 45 are fixedly embedded on the side of the connecting plate 43 close to the winding roller 2. A plurality of iron sheets are fixedly embedded on one side of the blocking plate 46, and magnetic attraction can be generated between these iron sheets and the magnets 45, which are used to stably place the blocking plate 46 on one side of the connecting plate 43. Both ends of the blocking plate 46 are provided with a clearance groove, and a trapezoidal rubber block 47 (made of nitrile rubber, with a hardness of 75±3HA) is slidably connected in the two clearance grooves. A plurality of second springs 48 are fixed on one side of the trapezoidal rubber block 47, and one end of these second springs 48 is fixedly connected to the inner wall of one side of the clearance groove. The elastic force of the second spring 48 on the trapezoidal rubber block 47 can stably clamp the blocking plate 46 in the winding roller 2 and fix the welding wire on the outer wall of the winding roller 2. The tension of the second tension spring 39 is greater than the elastic force of the second spring 48, which can pull the blocking plate 46 into the winding roller 2.

[0028] Specifically, when the support arm 28 rotates to the left, it will push the trapezoidal lifting plate 30 to move upward. The upward movement of the trapezoidal lifting plate 30 will push the push plate 32 to move upward, and then drive the U-shaped rod 34 and the first piston plate 36 to move upward. The upward movement of the first piston plate 36 will suck the hydraulic oil in the hollow column 37 into the fixed plate 35, and at the same time drive the piston rod 40 to shrink into the oil groove at the bottom of the hollow column 37, thereby releasing the brake on the sleeve plate 53. At this time, the sleeve plate 53 moves toward the direction of the winding roller 2 under the tension of the second tension spring 39, and the connecting plate 43 drives the blocking plate 46 to move synchronously. During the movement, the blocking plate 46 will squeeze and fix the welding wire on the outer wall of the winding roller 2 to prevent the welding wire from falling off the winding roller 2. The trapezoidal rubber block 47 will squeeze the inner wall of one side of the winding roller 2 under the action of the second spring 48, thereby fixing the blocking plate 46 in the winding roller 2.

[0029] Reference Figure 3 , a lifting groove 4 is provided in the base 1. In the lifting groove 4, a guide rod 5 (the material is GCr15 bearing steel, the surface hardness is HRC58-62, and meets the ISO 286-2 standard) is longitudinally fixed, and the outer wall sliding sleeve of the guide rod 5 is provided with a U-shaped seat 10, so that the U-shaped seat 10 can be stably lifted and lowered along the guide rod 5 in the lifting groove 4. At the same time, a screw rod 6 is longitudinally rotatably connected in the lifting groove 4, and the screw rod 6 is threadedly connected to the U-shaped seat 10, so when the screw rod 6 rotates, the U-shaped seat 10 can be driven to lift and lower in the lifting groove 4.

[0030] Reference Figure 3 and Figure 4, arc-shaped grooves 7 are provided on both sides of the top of the U-shaped seat 10. These arc-shaped grooves 7 are matched with the shape of the winding roller 2 for stably supporting the winding roller 2. In addition, a plurality of first sliding grooves 8 are provided on both sides of the U-shaped seat 10, and a plurality of support plates 9 are fixed to the inner walls of both sides of the lifting groove 4. These support plates 9 are slidably matched with the first sliding grooves 8. Such a design can not only keep the U-shaped seat 10 stable during the lifting process, but also support the winding roller 2 through the support plates 9 when the U-shaped seat 10 is received in the lifting groove 4.

[0031] Refer to Figures 1 - 4 , on one side of the base 1, a material guiding plate 57 is also fixed, which facilitates the removal of the winding roller 2 from the base 1. During use, first, the winding roller 2 rolls along the material guiding plate 57 towards the top of the base 1 and is supported by a plurality of support plates 9. Then, the motor drives the screw rod 6 to rotate, and the rotation of the screw rod 6 drives the U-shaped seat 10 to move upward, so that the bottom sides of both sides of the winding roller 2 just extend into the corresponding arc-shaped grooves 7. Then, the U-shaped seat 10 continues to rise, pushing the winding roller 2 upward until the winding roller 2 is coaxially aligned with the rotating rod 13, completing the installation of the winding roller 2.

[0032] Embodiment 2: Refer to Figures 11 - 13 , two air bags 49 are also fixed to the inner wall of the bottom of the lifting groove 4. These two air bags 49 are located below the U-shaped seat 10. One side of the air bag 49 is fixed with an air guide pipe 50. Second piston plates 51 are hermetically and slidably connected in both circular grooves 41. The tops of the second piston plates 51 are respectively fixed to the tops of the two lifting rods 42, and the other end of the air guide pipe 50 is fixedly extended into the circular groove 41, and the connection part of the air guide pipe 50 and the circular groove 41 is located below the second piston plate 51.

[0033] When the U-shaped seat 10 moves downward, it will squeeze the air bag 49, causing the gas in the air bag 49 to be injected into the circular groove 41 through the air guide pipe 50 and pushing the second piston plate 51 and the lifting rod 42 to rise. The rising of the lifting rod 42 will synchronously drive the connecting plate 43 to move upward, thus avoiding the connecting plate 43 from blocking the winding roller 2 when the winding roller 2 rolls off the base 1 in the later stage. Such a design not only increases the functionality of the device, but also improves its convenience and safety in use.

[0034] A method for using a wire drawing device for wire processing includes the following steps: S1. When the welding wire is traction-wound, the winding roller 2 is pushed to roll along the material guide plate 57 towards the top of the base 1, and the winding roller 2 can be supported by multiple support plates 9. Then, the motor drives the screw rod 6 to rotate, driving the U-shaped seat 10 to move upward. The bottom sides of both sides of the winding roller 2 just extend into the corresponding arc grooves 7. Then, the U-shaped seat 10 jacks up the winding roller 2 until the winding roller 2 is coaxial with the rotating rod 13. The output shaft of the cylinder 12 pushes the moving seat 11 to move towards the middle. The hexagonal block 3 is inserted and matched with the hexagonal groove 15, so that the adapter sleeve 14 can drive the winding roller 2 to rotate to complete the winding operation. After that, one end side of the welding wire is wound around the outer wall of the top of the first guide wheel 18 and the outer wall of the bottom of the second guide wheel 24, and then penetrates through the guide ring 25 and is fixed on the surface of the winding roller 2; S2. During winding, the motor drives the reciprocating screw rod 16 to rotate. The reciprocating screw rod 16 drives the rotating rod 13 and the adapter sleeve 14 to rotate through the synchronous pulley and synchronous belt. The adapter sleeve 14 drives the winding roller 2 to rotate for winding operation. During the winding process, the reciprocating screw rod 16 drives the first guide wheel 18, the second guide wheel 24 and the guide ring 25 to move reciprocally through the reciprocating frame 17, so that the welding wire can be evenly wound around the outer wall of the winding roller 2. In addition, the thrust applied by the first spring 23 to the sliding block 20 can make the first guide wheel 18 and the second guide wheel 24 cooperate to tighten the welding wire, so that the welding wire can be stably wound around the outer wall of the winding roller 2. When the tension of the welding wire is too high, the second guide wheel 24 is pushed to move upward, and the first spring 23 contracts. Then, the first spring 23 increases the thrust on the pressure sensor 22. When the pressure sensor 22 detects that the pressure reaches a certain value, the rotation speed of the reciprocating screw rod 16 is slowed down to prevent the welding wire from being too tight and breaking; S3. In addition, the arc-shaped plate 55 and the rolling cylinder 56 tightly fit the welding wire on the outer wall of the winding roller 2 under the action of the torsion spring 29, which can make the welding wire wind around the winding roller 2 and prevent the welding wire from loosening. When the winding roller 2 winds the welding wire, the outer diameter of the winding roller 2 gradually increases. The support arm 28 rotates to the left and pushes the trapezoidal lifting plate 30 to move upward. The cooperation between the trapezoidal lifting plate 30 and the pushing plate 32 pushes the U-shaped rod 34 and the first piston plate 36 to move upward. The first piston plate 36 sucks the hydraulic oil in the hollow column 37 into the fixed plate 35. The piston rod 40 contracts into the oil groove at the bottom of the hollow column 37 under the action of the hydraulic oil. The piston rod 40 releases the braking on the sleeve plate 53. The sleeve plate 53 moves towards the winding roller 2 under the pulling force of the second tension spring 39. The connecting plate 43 drives the blocking plate 46 to move synchronously. When moving, the blocking plate 46 squeezes and fixes the welding wire on the outer wall of the winding roller 2 to prevent the welding wire from falling off the winding roller 2. The trapezoidal rubber block 47 squeezes the inner wall of one side of the winding roller 2 under the action of the second spring 48 to fix the blocking plate 46 in the winding roller 2; S4. After the wire coiling roller 2 finishes coiling the welding wire, pull the connecting plate 43 and the sleeve plate 53 outward so that the blocking plate 46 disengages from one side of the connecting plate 43. Then, the lead screw 6 drives the U-shaped seat 10 to move downward to place the wire coiling roller 2 on the plurality of support plates 9. When the U-shaped seat 10 moves downward, the gas in the airbag 49 is squeezed into the circular groove 41. At this time, the gas pushes the second piston plate 51 and the lifting rod 42 to move upward, synchronously driving the connecting plate 43 to move upward, so as to prevent the connecting plate 43 from blocking the wire coiling roller 2 when it rolls off the base 1 later. After the wire coiling roller 2 disengages from the base 1, the push plate 32 and the support arm 28 are reset under the action of the first tension spring 33 and the torsion spring 29, and the piston rod 40 moves downward again to block the sleeve plate 53.
