Description

Technical Field

[0001] The invention relates to a flux-cored welding wire processing technology, in particular to a wire drawing machine for producing the flux-cored welding wire. Background Art

[0002] Flux-cored welding wire is also called powder-cored welding wire or tubular welding wire. It is divided into two categories: gas-entrained and non-gas-entrained. The surface of flux-cored welding wire is the same as solid welding wire, and is made of low-carbon steel or low-alloy steel with good plasticity. Its manufacturing method is to first roll the steel strip into a U-shaped cross-section, then add the welding powder prepared according to the dosage into the U-shaped steel strip, roll it tightly with a rolling mill, and finally draw it into flux-cored welding wires of different specifications. During the processing of flux-cored welding wire, a wire drawing machine is required for wire drawing production.

[0003] As disclosed in the invention with authorization announcement number CN114769338B, a wire drawing device for producing flux-cored welding wire includes a shell, a wire drawing template, a wire drawing hole and a wire guide roller, and slide grooves are provided inside the wire drawing template and on the upper and lower sides of the wire drawing hole. The scheme drives the wire guide roller and the reciprocating wire rod to rotate by the welding wire, so that the reciprocating magnetic block moves back and forth in the active cavity. The welding wire passes through the wire drawing hole, so that the slider overcomes the potential energy of the spring and moves, causing contact I and contact II to be connected, thereby increasing the magnetic force of the electromagnetic block corresponding to the wire drawing hole and adsorbing the electromagnetic guide wheel, prompting the electromagnetic guide wheel to align with the position of the wire drawing hole, so that the welding wire on the electromagnetic guide wheel can pass through the wire drawing hole in a straight line, effectively eliminating the angle between the welding wire and the wire drawing hole, avoiding uneven wire drawing caused by the angle between the welding wire and the wire drawing hole, and improving the quality of the finished welding wire. However, the above technical scheme has the following problems: during the wire guiding process, it is impossible to position the longitudinal and lateral movement of the welding wire, which may easily cause the welding wire guide to deviate and loosen. During the guiding, the welding wire cannot be automatically lubricated and cooled, which may easily cause wear. At the same time, it is impossible to reciprocate and orderly wind the wire after drawing, and the overall processing efficiency is not high. Summary of the invention

[0004] The technical problem to be solved by the present invention is: to provide a wire drawing machine for the production of flux-cored welding wire, which solves the problem that the prior art cannot position the longitudinal and lateral movements of the welding wire during the welding wire guiding process, which easily causes the welding wire guiding to deviate and loosen, and cannot automatically lubricate and cool the welding wire during guiding, which easily causes wear.

[0030] The flux-cored welding wire is inserted from the first introduction roller 202, and passes through the gap between the first positioning roller 208 and the second positioning roller 213, and then passes through the second introduction roller 204, and then the flux-cored welding wire is tensioned by the first tensioning roller 3 and the second tensioning roller 4. The flux-cored welding wire is connected to the winding roller 6 through the reciprocating guide mechanism 5.

[0031] Second embodiment

[0032] See also Figure 3 , Figure 5 as well as Figure 6The longitudinal positioning component includes an oil storage box 205, which is arranged on the top of the first stand 206 and the second stand 207. A carrier 216 is arranged at the bottom of the oil storage box 205. A limiting structure for positioning the longitudinal movement of the welding wire is rotatably arranged in the carrier 216, which can position the longitudinal movement of the welding wire and prevent the longitudinal movement of the welding wire, thereby ensuring the stability of the welding wire during introduction. The limiting structure includes an inner roller 217, which is rotatably connected to a bearing sleeve 219 through a ball bearing 218. The bearing sleeve 219 is arranged on both sides of the carrier 216, and a limiting sleeve 221 is arranged on the outer surface of the inner roller 217. The inner roller 217 and the limiting sleeve 221 can rotate smoothly in the carrier 216 and guide the movement of the welding wire. A guide tube 215 is also arranged in the carrier 216. One end of the guide tube 215 is connected to the oil storage box 205, and the other end of the guide tube 215 is connected to the bearing sleeve 219. The oil in the oil storage box 205 can be transported to the bearing sleeve 219. A plurality of overflow holes 220 are equidistantly arranged on the outer surface of the inner roller 217. The overflow holes 220 are connected to the limiting sleeve 221, and the lubricating oil can be guided to the limiting sleeve 221. The limiting sleeve 221 coats the lubricating oil on the welding wire to lubricate and cool the welding wire.

[0033] When the flux-cored welding wire is being input, the flux-cored welding wire drives the limit sleeve 221 and the inner roller 217 to rotate on the bearing sleeve 219. At this time, the longitudinal position of the flux-cored welding wire can be limited to prevent it from longitudinal movement. At the same time, the cold lubricating oil in the oil storage box 205 is transported to the bearing sleeve 219 through the guide tube 215. The bearing sleeve 219 transports the cold lubricating oil to the inner roller 217. The overflow hole 220 transports the cold lubricating oil to the limit sleeve 221. The limit sleeve 221 absorbs the cold lubricating oil. When the flux-cored welding wire is input, as the limit sleeve 221 rotates, the cold lubricating oil can be coated on the flux-cored welding wire to cool and lubricate it.

[0034] Specifically, the oil storage box 205 is also provided with an oil filling port 214 , which can deliver cold lubricating oil into the oil storage box 205 .

A ball screw 503 is rotatably arranged in the outer frame 501, a nut seat 511 is arranged on the ball screw 503, a pay-off frame 512 is arranged at the bottom of the nut seat 511, a pay-off roller 513 is rotatably arranged in the pay-off frame 512, a limit plate 517 is arranged on the pay-off roller 513, a transverse plate 514 is also arranged in the pay-off frame 512, a transverse frame 515 is arranged on one side of the transverse plate 514, a limit roller 516 corresponding to the limit plate 517 is arranged in the transverse frame 515, and the ball screw 503 is also arranged with The driving motor 509 located on one side of the outer frame 501 is connected, and can adjust the lateral position of the winding of the welding wire, and can wind the welding wire on the winding roller 6 in an orderly manner. The first touch rod 502 and the second touch rod 510 are respectively arranged on both sides of the nut seat 511. The first touch rod 502 corresponds to the forward rotation travel switch 504 on one side of the outer frame 501, and the second touch rod 510 corresponds to the reverse rotation travel switch 508 on the other side of the outer frame 501. It can automatically control the forward rotation and lateral rotation of the ball screw 503, and then automatically adjust the winding position of the welding wire.

[0037] The flux-cored welding wire is passed through the gap between the pay-off roller 513 and the limiting roller 516 and connected to the winding roller 6. When the winding roller 6 is winding the flux-cored welding wire, the ball screw 503 is driven to rotate in the opposite direction by the driving motor 509, and the nut seat 511 drives the pay-off frame 512 to move. The pay-off frame 512 simultaneously drives the pay-off roller 513 and the limiting roller 516 to move laterally, and adjusts the lateral winding position of the welding wire. The first touch rod 502 and the second touch rod 510 are driven to move by the movement of the nut seat 511. When the first touch rod 502 contacts the forward rotation stroke switch 504, the ball screw 503 rotates in the forward direction, and then the nut seat 511 is reset. When the second touch rod 510 contacts the reverse rotation stroke switch 508, the ball screw 503 rotates in the opposite direction, so that the nut seat 511 moves back and forth laterally, and the flux-cored welding wire is wound onto the winding roller 6 in an orderly and uniform manner.

[0038] Furthermore, a linear slider 506 is arranged on the top of the nut seat 511, and the linear slider 506 is slidably arranged in the linear slide groove 507, and the linear slide groove 507 is arranged on one side of the guide frame 505, and the guide frame 505 is arranged in the outer frame 501. When the nut seat 511 moves, it drives the linear slider 506 to move in the linear slide groove 507, thereby improving the guiding performance of the nut seat 511 when it moves.

[0039] Specifically, a winding frame 7 is arranged on one side of the top of the frame 9, and a winding roller 6 is arranged inside the winding frame 7. The winding roller 6 is connected to the driving shaft of a winding motor 8 located on one side of the winding frame 7, so that the welding wire can be quickly wound up. The winding roller 6 is driven to rotate by the winding motor 8, and the flux-cored welding wire is wound onto the winding roller 6.
