Description

Technical Field

[0001] The invention relates to the technical field of welding wire drawing equipment, and in particular to a flux-cored welding wire drawing equipment. Background Art

[0002] Flux-cored wire drawing equipment is a type of welding material production equipment that has developed rapidly in recent years. It has the advantages of high efficiency, excellent processability, less spatter, high-quality welding and easy automation. The production process of flux-cored wire mainly includes the following steps: Using strip steel to produce flux-cored wire is a mature method. First, the thin steel strip is cut into small pieces, rolled into a U-shaped groove, and then filled with flux core. The steel strip filled with flux core is rolled into an O-shaped tube by a roller and drawn.

[0003] During the wire drawing process, the welding wire is usually fixed on the reel, and the wire is continuously stretched by rotating the reel. When the reel starts to rotate, the welding wire will be continuously pulled out as the reel rotates. The speed of the reel determines the wire drawing speed. The welding wire will be gradually stretched to the required diameter when passing through a series of wire drawing dies. Each die will stretch the welding wire to a certain extent, gradually reducing its diameter. As more and more welding wire is wound on the reel, the diameter of the reel will become larger and larger. The problem at this time is that the angular velocity of the reel remains unchanged, while the linear velocity at the edge of the reel will gradually increase, so that the wire drawing speed will become faster and faster, which will cause the wire drawing speed to become uneven. Unstable speed may cause scratches, pits or other damage on the surface of the welding wire, affecting the appearance and welding performance of the welding wire. Changes in drawing speed may affect the uniform distribution of the flux core, resulting in unstable chemical composition and welding characteristics of the flux cored wire. Summary of the invention

DETAILED DESCRIPTION

[0032] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0033] The components of the embodiments of the present invention generally described and shown in the drawings herein may be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0036] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] See also Figures 1 to 12 As shown, a flux-cored welding wire drawing device proposed by the present invention comprises a frame, on which a reel 1 for winding the welding wire is rotatably mounted. When the welding wire is stretched, one end of the welding wire needs to be fixed on the reel 1 first, and the welding wire can be stretched by rotating the reel 1. A wiring mechanism 3 for evenly distributing the welding wire on the reel 1 is mounted on the frame, and a power mechanism 2 for driving the reel 1 to rotate is mounted on the frame. The power mechanism 2 comprises a motor 201 fixedly mounted on the frame, a first pulley 202 is fixedly mounted on the output shaft of the motor 201, a second pulley 203 is fixedly mounted on the reel 1, and a transmission belt 204 is provided on the first pulley 202 and the second pulley 203. The first pulley 202 is driven to rotate by the motor 201, and the second pulley 203 can be driven to rotate by the transmission of the transmission belt 204. The rotating second pulley 203 can drive the reel 1 fixedly connected thereto to rotate, thereby winding the welding wire on the reel 1 and stretching the welding wire.

[0038] The wiring mechanism 3 includes a guide rod 301 fixedly mounted on the frame and a reciprocating screw rod 302 rotatably mounted on the frame. A guide block 303 is slidably mounted on the guide rod 301. A connecting hole 304 is provided on the guide block 303. The guide block 303 is threadedly connected with the reciprocating screw rod 302. A linkage belt 305 is installed on the reel 1 and the reciprocating screw rod 302. When the reel 1 rotates, the linkage belt 305 will be driven to rotate. The reciprocating screw rod can be rotated through the transmission of the linkage belt 305, and then the guide block 303 can be driven to reciprocate. When the welding wire passes through the connecting hole 304, the welding wire can be driven to reciprocate, and then the welding wire can be evenly laid on the reel 1.

[0039] Furthermore, the frame is fixedly mounted with a first die 4 and a second die 401, and a plurality of guide wheels 402 are rotatably mounted between the first die 4 and the second die 401. The welding wire can be stretched by the first die 4 and the second die 401 by passing the welding wire through the first die 4 and the second die 401 in sequence, so that the welding wire is stretched multiple times to form a final desired shape, and the welding wire is supported and guided by the plurality of guide wheels 402.

[0040] The flux-cored welding wire drawing device of this embodiment also includes a wire-retracting and releasing mechanism installed on the frame and connected to the wiring mechanism in a transmission manner. The wire-retracting and releasing mechanism periodically retracts and releases the welding wire as the welding wire moves along the axis of the reel 1. When the welding wire moves back and forth with the guide block 303, the welding wire will be stretched, such as: when the welding wire is located in the middle of the reel 1, the moving speed of the welding wire will be consistent with the rotation speed of the reel 1, and when the welding wire moves to both sides of the reel 1, the guide block 303 will pull the welding wire to one side, and the speed of the welding wire will increase, which makes the speed of the welding wire gradually change when the welding wire moves back and forth on the reel 1. The wire-retracting and -releasing mechanism comprises a lifting seat 5 slidably mounted on a frame, a group of connecting wheels 501 are rotatably mounted on the lifting seat 5, a connecting rod 502 is fixedly mounted on the lifting seat 5, a first oil barrel 503 is fixedly mounted on the frame, the connecting rod 502 is slidably connected to the first oil barrel 503 and is sealed, and the wire-retracting and -releasing mechanism also comprises a transmission assembly that is transmission-connected to the guide block 303.

[0041] By passing the welding wire through the connecting wheel 501 and driving the lifting seat 5 to move up and down through the connecting rod 502, the welding wire can be tensioned and released. When the welding wire moves toward the edge of the reel 1 along with the guide block 303, the welding wire can be released by raising the height of the lifting seat 5, thereby preventing the movement of the guide block 303 from affecting the speed of the welding wire.

[0042] Furthermore, the transmission assembly includes a pressure rod 504 fixedly mounted on the guide block 303 and a second oil barrel 505 fixedly mounted on the frame. The pressure rod 504 is slidably connected to the second oil barrel 505 and sealed. The second oil barrel 505 corresponds to the first oil barrel 503 at both ends and is connected through the first oil pipe 506. When the guide block 303 moves, the pressure rod 504 is driven to move, and the moving pressure rod 504 will move inside the second oil barrel 505. Hydraulic oil is provided in the first oil barrel 503, the second oil barrel 505 and the first oil pipe 506. When the hydraulic pressure inside the second oil barrel 505 is squeezed into the first oil barrel 503, the first oil barrel 503 will drive the connecting rod 502 to rise, and then the height of the lifting seat 5 can be controlled as the position of the guide block 303 changes, thereby preventing the guide block 303 from interfering with the moving speed of the welding wire.

[0043] It should be noted that the second pulley 203 includes two disks 2031, and the two disks 2031 are provided with a plurality of slide grooves 2032, and tension blocks 609 are slidably installed in the slide grooves 2032, and the plurality of tension blocks 609 are arranged in a circular array. By changing the diameter of the circle formed by the plurality of tension blocks 609, the transmission ratio between the first pulley 202 and the second pulley 203 can be controlled, and thus the rotation speed of the reel 1 can be controlled.

[0044] Furthermore, the flux-cored wire drawing device of this embodiment also includes a constant speed control component, which is installed on the frame. The constant speed control component controls the rotation speed of the reel 1 according to the current diameter superimposed after the reel 1 is wound with the welding wire. The constant speed control component includes two support tubes 6 fixedly installed on the frame, the two support tubes 6 are located at the bottom of both sides of the reel 1, and abutment rods 601 are slidably installed in the support tubes 6, a first spring 602 is fixedly installed on the support tube 6, the other end of the first spring 602 is fixedly connected to the abutment rod 601, a round rod 603 is fixedly installed on the abutment rod 601, two third oil barrels 604 are fixedly installed on the frame, the third oil barrel 604 corresponds to the round rod 603 one by one and is slidably connected, and a sealing treatment is provided between the round rod 603 and the third oil barrel 604, and the constant speed control component also includes a linkage component, and the linkage component controls multiple tensioning blocks 609 to scale according to the position of the round rod 603. The elastic force of the first spring 602 can make the abutment rod 601 always abut against the reel 1 or the welding wire. As more and more welding wire is wound on the reel 1, the total diameter of the reel 1 will gradually increase, and the abutment rod 601 can be pushed downward. The downward moving abutment rod 601 will drive the round rod 603 to descend, and the size of the circle formed by multiple tensioning blocks 609 can be controlled through the transmission of the linkage assembly.

[0045] Specifically, the linkage assembly includes a fourth oil barrel 605 fixedly mounted on the frame, a push rod 606 is slidably mounted in the fourth oil barrel 605, a three-way joint 607 is fixedly mounted on the fourth oil barrel 605, the third oil barrel 604 is connected to the three-way joint 607 through a second oil pipe 608, a linkage rod 610 is slidably mounted on the disc 2031, a driving disk 611 is fixedly mounted on the linkage rod 610, a plurality of connecting rods 612 are rotatably mounted on the driving disk 611, and the other ends of the connecting rods 612 correspond one-to-one to the tensioning block 609 and are rotatably connected. The third oil barrel 604, the fourth oil barrel 605 and the second oil pipe 608 are all filled with hydraulic oil. When the abutment rod 601 descends, the hydraulic oil inside the third oil barrel 604 will be squeezed into the fourth oil barrel 605, and the hydraulic oil entering the fourth oil barrel 605 will push the push rod 606 to move. Since the push rod 606 is rotatably connected with the linkage rod 610, the moving push rod 606 will drive the driving disk 611 to move through the linkage rod 610, and the moving driving disk 611 will drive multiple connecting rods 612 to move. The size of the circle formed by the multiple tensioning blocks 609 can be changed through the transmission of the connecting rod 612. At this time, as the abutment rod 601 descends, the diameter of the circle formed by the multiple tensioning blocks 609 will be reduced, thereby reducing the angular velocity of the reel 1 to keep the linear velocity of the edge of the reel 1 unchanged, thereby keeping the speed at which the welding wire is stretched unchanged, thereby keeping the same batch of welding wires wound on the same reel 1 at a constant stretching speed, effectively ensuring the same quality of the same batch of welding wires.

[0046] Among them, the frame is fixedly mounted with a telescopic rod 7, the telescopic rod 7 is raised and fixedly mounted with a pulley seat 701, the pulley seat 701 is fixedly mounted with a second spring 702, the other end of the second spring 702 is fixedly connected to the telescopic rod 7, and the pulley seat 701 is rotatably mounted with a tensioning wheel 703, the tensioning wheel 703 abuts against the transmission belt 204. The tensioning wheel 703 can keep the transmission belt 204 in a tensioned state at all times to ensure the transmission effect of the transmission belt 204.

[0047] The working principle of this embodiment is as follows: the first pulley 202 is driven to rotate by the motor 201, and the second pulley 203 is driven to rotate by the transmission belt 204, and the rotating second pulley 203 can drive the reel 1 fixed thereto to rotate, thereby winding the welding wire around the reel 1 and stretching the welding wire. When the reel 1 rotates, it will drive the linkage belt 305 to rotate, and the reciprocating screw rod can be driven to rotate by the transmission of the linkage belt 305, thereby driving the guide block 303 to reciprocate, so that the welding wire passes through the connecting hole 304, and thus drives the welding wire to reciprocate, thereby making the welding wire evenly laid on the reel 1.

[0048] When the guide block 303 moves, it will drive the pressure rod 504 to move, and the moving pressure rod 504 will move inside the second oil barrel 505. The first oil barrel 503, the second oil barrel 505 and the first oil pipe 506 are all provided with hydraulic oil. When the hydraulic pressure inside the second oil barrel 505 is squeezed into the first oil barrel 503, the first oil barrel 503 will drive the connecting rod 502 to rise, and then the height of the lifting seat 5 can be controlled as the position of the guide block 303 changes, thereby preventing the guide block 303 from interfering with the moving speed of the welding wire.

[0049] When the abutment rod 601 descends, the hydraulic oil inside the third oil barrel 604 will be squeezed into the fourth oil barrel 605, and the hydraulic oil entering the fourth oil barrel 605 will push the push rod 606 to move. Since the push rod 606 is rotatably connected to the linkage rod 610, the moving push rod 606 will drive the driving disk 611 to move through the linkage rod 610, and the moving driving disk 611 will drive multiple connecting rods 612 to move. The size of the circle formed by the multiple tensioning blocks 609 can be changed through the transmission of the connecting rod 612. At this time, as the abutment rod 601 descends, the diameter of the circle formed by the multiple tensioning blocks 609 will be reduced, thereby reducing the angular velocity of the reel 1 to keep the linear velocity of the edge of the reel 1 unchanged, thereby keeping the speed at which the welding wire is stretched unchanged, thereby keeping the same batch of welding wires wound on the same reel 1 at a constant stretching speed, effectively ensuring the same quality of the same batch of welding wires.

[0050] The above specific embodiments are only several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
