Description

Technical Field

[0002] Welding wire is a metal wire material used as filler metal and conductor in welding. It is widely used in various welding processes and is in high demand. In production, it is often wound with a wire take-up device. Because the welding wire is long and linear feed takes up a lot of space, it needs to be guided to save space.

[0003] The existing technology still has the following shortcomings in the traction and winding process:

[0004] 1. In the prior art, after the welding wire is pulled and reeled, a worker must manually secure one end of the reeled wire to the reel to prevent it from coming loose.

[0005] 2. During the traction and reeling operation, the welding wire tends to relax on the surface of the reeling roller, which in turn causes the welding wire to become disorderly tangled during the reeling process, affecting the neat arrangement of the welding wire on the reeling roller.

[0048] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0049] Example 1: Reference Figure 1 、 Figure 2 and Figure 4 , a traction clamping assembly, relating to the field of welding wire production technology, comprises a base 1, a winding roller 2 is provided on the top of the base 1, and a U-shaped frame 52 is fixed on the top of the base 1;

[0050] On the upper surface of the base 1, two movable seats 11 that slide along the X-axis direction are provided. The two movable seats 11 are respectively located at both ends of the winding roller 2. The sides of the two movable seats 11 that are close to each other are rotatably connected with an adapter sleeve 14. The sides of the two adapter sleeves 14 that are close to each other are provided with a hexagonal groove 15. Both ends of the winding roller 2 are fixed with a hexagonal block 3, and the hexagonal block 3 (tolerance grade H7) and the hexagonal groove 15 (tolerance grade H8) form a clearance fit. The clearance is controlled within the range of 0.05-0.12mm. Two cylinders 12 (power sources) are fixedly passed through the U-shaped frame 52. The output shafts of the two cylinders 12 are respectively fixedly connected to the two movable seats 11 for driving the two adapter sleeves 14 to move toward the middle and plug into the hexagonal block 3. A rotating rod 13 is rotatably passed through the two movable seats 11. The ends of the two rotating rods 13 that are close to each other are fixedly connected to the two adapter sleeves 14 respectively, and the ends of the two rotating rods 13 that are away from each other both pass through the U-shaped frame 52. A reciprocating screw 16 located above the winding roller 2 is rotatably connected inside the U-shaped frame 52. The reciprocating screw 16 and the two rotating rods 13 are connected by synchronous wheels and synchronous belts. The synchronous belt can be an MXL type with a pitch of 0.08 inches and a bandwidth of 9mm. The synchronous wheel sliding sleeve on the rotating rod 13 is provided on the outer wall of the rotating rod 13 and can be horizontally slidably connected by the slider sliding groove and the slider. There is no relative rotation between the synchronous wheel and the rotating rod 13, and the two rotate synchronously. The synchronous wheel on the rotating rod 13 is rotatably connected to the inner wall of one side 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.

[0051] Reference Figure 1 and Figure 2 A traction device for welding wire processing includes the above-mentioned traction clamping assembly, which includes a reciprocating frame 17 sliding in a U-shaped frame 52 for evenly winding the welding wire on the winding roller 2.

[0052] Reference Figure 2 and Figure 7A fixing frame 26 is also fixed to the top of the base 1. A rolling drum 56 is provided on one side of the fixing frame 26. The rolling drum 56 extends into the winding roller 2. When the welding wire is wound around the outer wall of the winding roller 2, the rolling drum 56 can keep the welding wire tightly against the outer wall of the winding roller 2, ensuring the tightness and neatness of the welding wire winding.

[0053] Reference Figure 1 and Figure 9 A connecting plate 43 is provided in 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 to the outer wall of the winding roller 2 to prevent the welding wire from coming loose.

[0054] Reference 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 provided at one end of the reciprocating frame 17, and two second sliding grooves 19 provided 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 on the top of the sliding block 20, and a pressure sensor 22 is fixed in the circular groove 21. The side of the two sliding blocks 20 that is close to each other is rotatably connected to the same second guide wheel 24, and the bottom end of the first spring 23 contacts 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 enable the first guide wheel 18 and the second guide wheel 24 to cooperate to tighten the welding wire, ensuring that the welding wire can be stably wound on the outer wall of the winding roller 2. At the same time, when the welding wire tension is too high, it pushes the second guide wheel 24 upward, causing the first spring 23 to contract, increasing the thrust on the pressure sensor 22. When the pressure sensor 22 detects that the pressure has reached a certain value (the PLC controller will reduce the motor speed to 20%-65% of the rated value), the speed of the reciprocating screw 16 is slowed to prevent the welding wire from being overtightened and breaking. Furthermore, a fixed slide 54 is fixed within the U-shaped frame 52. The reciprocating frame 17 slides around the outer wall of the fixed slide 54 and slidably engages with the spiral groove on the outer wall of the reciprocating screw 16. When the reciprocating screw 16 rotates, it drives 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, ensuring that the welding wire is evenly wound around the outer wall of the winding roller 2.

[0055] Reference Figure 2 、 Figure 7 and Figure 8In order to ensure that the welding wire is in close contact with the outer wall of the winding roller 2, a fitting structure is provided in the device. When the winding roller 2 rotates for the winding operation, the rolling drum 56 can roll along with the winding of the welding wire, making the welding wire close to the outer wall of the winding roller 2. The fitting structure includes a rotating shaft 27 rotatably mounted on the side of the fixed frame 26 close to the winding roller 2. Two support arms 28 are fixedly sleeved on the outer wall of this rotating shaft 27. A torsion spring 29 is fixed on the side of the two support arms 28 facing away from each other, and the other ends of the two torsion springs 29 are respectively fixedly connected 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. A common arc-shaped plate 55 is fixed at one end of the two support arms 28, and a rolling drum 56 is rotatably mounted inside this arc-shaped plate 55. Under the action of the torsion spring 29, the support arm 28 and the arc plate 55 will press the welding wire tightly against the outer wall of the winding roller 2, and the fitting method of the arc plate 55 and the rolling cylinder 56 can effectively make the welding wire tightly wound on the winding roller 2 to prevent the welding wire from loosening.

[0056] Reference Figure 2 、 Figure 7 、 Figure 8 and Figure 9 To secure the welding wire with the blocking plate 46, a positioning mechanism is provided in the device. This mechanism drives the connecting plate 43 and blocking plate 46 into the take-up roller 2 and secures the welding wire. Simultaneously, the operation of the contact mechanism drives the blocking plate 46 to move and secure the welding wire. The positioning mechanism comprises two U-shaped rods 34 that slide through the U-shaped frame 52. A push plate 32 is secured to one end of each U-shaped rod 34. Two guide slots 31 are provided at the top of the fixed frame 26, and the push plates 32 slide within these slots, respectively. A first tension spring 33 is secured between the bottom inner wall of the guide slots 31 and the bottom of the push plates 32. Two trapezoidal lifting plates 30 are slidably connected to one side of the fixed frame 26. These two trapezoidal lifting plates 30 engage the support arm 28. Rotation of the support arm 28 drives the trapezoidal lifting plates 30 upward. The push plates 32 are located above the trapezoidal lifting plates 30, so upward movement of the trapezoidal lifting plates 30 pushes the push plates 32 upward.

[0057] Reference Figure 1 、 Figure 2 、 Figure 9 and Figure 10A fixed plate 35 is fixed inside the U-shaped frame 52, and a hydraulic chamber is provided inside the fixed plate 35. In this hydraulic chamber, a first piston plate 36 is sealed and slidably connected. The other ends of the two U-shaped rods 34 extend into the fixed plate 35 and are fixedly connected to the top of the first piston plate 36. On the side of the fixed plate 35 away from the reciprocating frame 17, a hollow column 37 is fixed. This hollow column 37 is connected to the fixed plate 35, and the position where it is connected to the fixed plate 35 is located below the first piston plate 36. When the first piston plate 36 moves upward, the hydraulic oil in the hollow column 37 will be sucked into the fixed plate 35. On the outer wall of the hollow column 37, a sleeve plate 53 is provided in a sliding sleeve. A retaining ring 38 is fixed to the side of the sleeve plate 53 close to the fixed plate 35. A second tension spring 39 is fixed between the retaining ring 38 and the fixed 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, within which a piston rod 40 is sealingly and slidably connected. One side of the piston rod 40 has an inclined surface. Therefore, when the first piston plate 36 moves upward, it draws the hydraulic oil from the hollow column 37 into the fixed plate 35. Under the action of the hydraulic oil, the piston rod 40 contracts into the oil groove at the bottom of the hollow column 37. (A piston is mounted on the top of the piston rod 40, which is sealingly and slidably connected to the oil groove at the bottom of the hollow column 37.) At this point, the piston rod 40 no longer protrudes from the hollow column 37 and, consequently, does not contact the sleeve plate 53, thereby releasing the brake on the sleeve plate 53.

[0058] Reference Figure 9 and Figure 10 Two circular grooves 41 are provided at the top of the sleeve 53. The bottom inner walls of these two circular grooves 41 are sealed and slidably connected to a lifting rod 42. The bottom ends of these two lifting rods 42 are fixedly connected to the top of a connecting plate 43. Two retaining bars 44 are fixed to the side of the connecting plate 43 near the winding roller 2, which are used to place the blocking plate 46. At the same time, multiple magnets 45 are fixedly embedded on the side of the connecting plate 43 near the winding roller 2. Multiple iron layers are fixedly embedded on one side of the blocking plate 46. These iron layers and the magnets 45 can generate magnetic attraction to stably place the blocking plate 46 on one side of the connecting plate 43. A clearance groove is provided at both ends of the blocking plate 46. A trapezoidal rubber block 47 (made of nitrile rubber, hardness 75±3HA) is slidably connected to each of these clearance grooves. Multiple second springs 48 are fixed to one side of this trapezoidal rubber block 47, and one end of each second spring 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 pulling force 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.

[0059] Specifically, when the support arm 28 rotates to the left, it pushes the trapezoidal lifting plate 30 upward. The upward movement of the trapezoidal lifting plate 30 pushes the push plate 32 upward, thereby driving the U-shaped rod 34 and the first piston plate 36 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 retract into the oil groove at the bottom of the hollow column 37, releasing the brake on the sleeve plate 53. At this time, the sleeve plate 53 moves toward 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.

[0060] Reference Figure 3 The base 1 is provided with a lifting groove 4. A guide rod 5 (made of GCr15 bearing steel, with a surface hardness of HRC58-62, meeting ISO 286-2 standards) is longitudinally fixed within the lifting groove 4. A U-shaped seat 10 is slidingly sleeved on the outer wall of the guide rod 5, allowing the U-shaped seat 10 to be stably raised and lowered along the guide rod 5 within the lifting groove 4. Furthermore, a lead screw 6 is longitudinally and rotatably connected within the lifting groove 4. The lead screw 6 is threadedly connected to the U-shaped seat 10. Therefore, when the lead screw 6 rotates, it can drive the U-shaped seat 10 to rise and fall within the lifting groove 4.

[0061] 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 match the shape of the winding roller 2 and provide stable support for the winding roller 2. Furthermore, multiple first sliding grooves 8 are provided on both sides of the U-shaped seat 10, and multiple support plates 9 are fixed to the inner walls of the lifting slot 4 on both sides. These support plates 9 slide in conjunction with the first sliding grooves 8. This design not only ensures that the U-shaped seat 10 remains stable during the lifting process, but also supports the winding roller 2 through the support plates 9 when the U-shaped seat 10 is stored in the lifting slot 4.

[0062] Reference Figure 1-Figure 4 A guide plate 57 is also fixed to one side of the base 1, which facilitates the removal of the winding roller 2 from the base 1. During use, the winding roller 2 first rolls along the guide plate 57 toward the top of the base 1, supported by multiple support plates 9. Next, the motor drives the screw 6 to rotate, which drives the U-shaped seat 10 upward, so that the bottom of each side of the winding roller 2 extends exactly into the corresponding arc-shaped groove 7. Then, the U-shaped seat 10 continues to rise, pushing the winding roller 2 upward until the winding roller 2 and the rotating rod 13 are coaxially aligned, completing the installation of the winding roller 2.

[0063] Example 2: Reference Figure 11-13Two air bags 49 are also fixed to the bottom inner wall of the lifting groove 4, located below the U-shaped seat 10. An air duct 50 is fixed to one side of the air bag 49, and a second piston plate 51 is sealingly and slidably connected within each of the two circular grooves 41. The top of the second piston plate 51 is fixed to the top of the two lifting rods 42, while the other end of the air duct 50 is fixedly extended into the circular groove 41, and the connection between the air duct 50 and the circular groove 41 is located below the second piston plate 51.

[0064] When the U-shaped seat 10 moves downward, it squeezes the airbag 49, allowing the gas inside to flow through the air guide tube 50 into the circular groove 41, pushing the second piston plate 51 and the lifting rod 42 upward. The rise of the lifting rod 42 also causes the connecting plate 43 to move upward, preventing the connecting plate 43 from blocking the winding roller 2 when it later rolls off the base 1. This design not only increases the functionality of the device, but also improves its convenience and safety.

[0065] A method for using a traction device for welding wire processing comprises the following steps:

[0066] S1. When the welding wire is pulled and wound, the winding roller 2 is pushed along the guide plate 57 to roll toward the top of the base 1, and multiple support plates 9 can support the winding roller 2. Then the motor drives the screw rod 6 to rotate and drives the U-shaped seat 10 to move upward. The bottoms of both sides of the winding roller 2 just extend into the corresponding arc groove 7. Then the U-shaped seat 10 pushes the winding roller 2 upward until the winding roller 2 is coaxial with the rotating rod 13. The output shaft of the cylinder 12 pushes the movable seat 11 to move toward the middle. The hexagonal block 3 is plugged into 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 of the welding wire is wound around the top outer wall of the first guide wheel 18 and the bottom outer wall of the second guide wheel 24, and then passes through the guide ring 25 to be fixed on the surface of the winding roller 2.

[0067] When the welding wire is wound on the outer wall of the winding roller 2, the welding wire is wound on the outer wall of the winding roller 2. When the welding wire is wound on the outer wall of the winding roller 2, the welding wire is wound on the outer wall of the winding roller 2. When the welding wire is wound on the outer wall of the winding roller 2, the welding wire is wound on the outer wall of the winding roller 2. When the welding wire is wound on the outer wall of the winding roller 2, the welding wire is wound on the outer wall of the winding roller 2. When the welding wire is wound on the outer wall of the winding roller 2, the welding wire is wound on the outer wall of the winding roller 2. When the welding wire is wound on the outer wall of the winding roller 2, the welding wire is wound on the outer wall of the winding roller 2. When the welding wire is wound on the outer wall of the winding roller 2, the welding wire is wound on the outer wall of the winding roller 2. When the welding wire is wound on the outer wall of the winding roller 2, the welding wire is wound on the outer wall of the winding roller 2. When the welding wire is wound on the outer wall of the winding roller 2, the welding wire is wound on the outer wall of the winding roller 2. When the welding wire is wound on the outer wall of the winding roller 2, the welding wire is wound on the outer wall of the winding roller 2. When the welding wire is wound on the outer wall of the winding roller 2, the welding wire is wound on the outer wall of the winding roller 2. When the welding wire is wound on the outer wall of the winding roller 2, the welding wire is wound on the outer wall of the winding roller 2. When the welding wire is wound on the outer wall of the winding roller 2, the welding wire is wound on the outer wall of the winding roller 2

[0068] S3. In addition, the arc plate 55 and the rolling drum 56 are tightly fitted with the welding wire on the outer wall of the reel 2 under the action of the torsion spring 29, so that the welding wire can be wound on the reel 2 to prevent the welding wire from loosening. When the reel 2 reels the welding wire, the outer diameter of the reel 2 gradually increases, and 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, and the piston rod 40 releases the brake on the sleeve 53. The sleeve 53 moves toward 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. 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, fixing the blocking plate 46 in the winding roller 2;

[0069] S4. After the winding roller 2 has finished winding the welding wire, the connecting plate 43 and the sleeve plate 53 are pulled outward, so that the blocking plate 46 is detached from one side of the connecting plate 43. Then the screw rod 6 drives the U-shaped seat 10 to move downward to place the winding roller 2 on multiple 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, and synchronously drives the connecting plate 43 to move upward to avoid the connecting plate 43 from blocking the winding roller 2 when it rolls down from the base 1 later. When the winding roller 2 is detached 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.
