Description

Technical Field

[0001] This utility model relates to the field of welding wire continuous rolling technology, specifically a cold continuous rolling device for welding wire production. Background Technology

[0002] Welding wire is a metal wire used as filler metal or simultaneously as a conductor in welding. Most welding wires are rolled wires, including carbon steel welding wire, low alloy structural steel welding wire, alloy structural steel welding wire, stainless steel welding wire, and non-ferrous metal welding wire. Cold rolling, originally a steel strip forming process, can now also be used for forming welding wire.

[0003] Current cold rolling mills for welding wire forming are simple modifications of the original cold rolling mills for steel strips. In actual production, it is difficult to guarantee the roundness of the welding wire surface. Uneven deformation of the welding wire surface leads to excessive stress concentration in localized areas, uneven stress distribution, and difficulty in eliminating residual stress, thus affecting the quality of the welding wire. Therefore, we propose a cold rolling mill device for welding wire production. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide a cold rolling device for welding wire production, which solves the problem of uneven surface deformation of welding wire produced by current cold rolling devices.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A cold continuous rolling mill for welding wire production includes a housing, and an auxiliary processing mechanism is provided inside the housing.

[0007] The auxiliary processing mechanism includes a limiting seat fixedly connected inside the housing, a turntable rotatably connected to the limiting seat, a through hole for the welding wire to pass through the center of the turntable, and two mounting brackets slidably connected to one side of the turntable, each of the two mounting brackets being rotatably connected to a movable wheel.

[0008] Preferably, two guide rods are fixedly connected to the inner wall of the turntable. The guide rods are arranged radially along the turntable. Limiting blocks are slidably connected to the guide rods. The limiting blocks are elastically connected to the inner wall of the turntable by springs. One end of the limiting block is fixedly connected to the mounting bracket.

[0009] Preferably, the limiting seat is provided with a guide plate, the guide plate is coaxially arranged with the turntable, and the center of the guide plate is provided with a through hole for the welding wire to pass through. The end of the guide plate near the turntable is provided with an annular slide, and multiple fan-shaped blocks are distributed in a circular array in the annular slide, with a gap between two adjacent fan-shaped blocks.

[0010] The other end of the limiting block is fixedly connected to a movable rod, one end of which extends into the annular slide and can enter the gap.

[0011] Preferably, the auxiliary processing mechanism further includes a motor fixedly connected to the housing, a small gear fixedly connected to the output end of the motor, and a large gear fixedly connected to the outer peripheral wall of the turntable, the large gear meshing with the small gear.

[0012] Preferably, a reciprocating lead screw is fixedly connected to one end of the pinion, a moving block is meshed on the surface of the reciprocating lead screw, and a drive rod is fixedly connected to the moving block;

[0013] A transmission plate is fixedly connected to the guide plate, and an inclined slide is provided on the transmission plate. One end of the drive rod extends into the inclined slide.

[0014] Preferably, an arc-shaped plate is fixedly connected to the limiting seat, and an arc-shaped groove is provided on the guide plate. The arc-shaped plate is slidably connected to the inner wall of the arc-shaped groove, and the curvature of the arc-shaped plate is smaller than the curvature of the arc-shaped groove.

[0015] Preferably, the housing is provided with a first roll and a second roll, and the directions of the first roll and the second roll are perpendicular.

[0016] By employing the above technical solution, this utility model provides a cold continuous rolling apparatus for welding wire production. It possesses at least the following beneficial effects:

[0017] (1) The cold rolling device for producing welding wire can be equipped with an auxiliary processing mechanism.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Please see Figures 1-6 The present invention provides a technical solution as follows:

[0029] A cold continuous rolling apparatus for producing welding wire includes a housing 1, within which a first roll 2 and a second roll 3 are disposed, the first roll 2 and the second roll 3 being perpendicular in direction. This allows for directional rolling of the welding wire, resulting in a more uniform stress distribution and more uniform deformation of the welding wire. Multiple first rolls 2 and second rolls 3 are used to continuously roll the welding wire.

[0030] An auxiliary processing mechanism 4 is provided inside the housing 1.

[0031] The auxiliary processing mechanism 4 includes a limiting seat 41 fixedly connected inside the housing 1. A turntable 42 is rotatably connected to the limiting seat 41, and a through hole for the welding wire to pass through is opened in the center of the turntable 42. An annular plate 410 is fixedly connected to the limiting seat 41. An annular groove is opened on the outer circumference of the turntable 42. The annular plate 410 is rotatably connected to the inner wall of the annular groove, thereby limiting the turntable 42 and preventing the turntable 42 from detaching from the limiting seat 41.

[0032] Two mounting brackets 44 are slidably connected to one side of the turntable 42. Each mounting bracket 44 is rotatably connected to a movable wheel 43. The two movable wheels 43 are symmetrically arranged about a diameter of the turntable 42. The distance between the two movable wheels 43 is equal to the diameter of the welding wire. When the turntable 42 rotates, the two movable wheels 43 will move in a circle around the outer wall of the welding wire, thereby smoothing the uneven parts of the welding wire surface and improving the roundness and quality of the welding wire.

[0033] A drive assembly for driving the rotation of the turntable 42 is connected to the turntable 42.

[0034] The drive assembly includes a motor 412 fixedly connected to the housing 1. A pinion 413 is fixedly connected to the output end of the motor 412, and a large gear 414 is fixedly connected to the outer peripheral wall of the turntable 42. The large gear 414 meshes with the pinion 413. The motor 412 drives the pinion 413 to rotate, and the pinion 413 drives the large gear 414 to rotate through meshing, thereby realizing the rotation of the turntable 42.

[0035] In a preferred embodiment, the auxiliary processing mechanism 4 further includes a hammering assembly that drives the two movable wheels 43 to move relative to each other. The hammering assembly changes the continuous contact between the movable wheels 43 and the welding wire into intermittent contact. On the one hand, it can overcome the resistance caused by the direction of movement of the welding wire being perpendicular to the direction of rotation of the movable wheels 43, making the movement of the welding wire smoother. On the other hand, the hammering can eliminate the problem of uneven stress generated during the rolling process of the welding wire, thereby improving the quality of the welding wire.

[0036] Specifically, the hammering assembly includes two guide rods 46 fixedly connected to the inner wall of the turntable 42. The guide rods 46 are arranged radially along the turntable 42. Limiting blocks 45 are slidably connected to both guide rods 46. A sliding groove is provided in the turntable 42 for the two limiting blocks 45 to slide. The side of the limiting block 45 near the center of the turntable 42 is elastically connected to the inner wall of the sliding groove by a spring. The spring force allows the limiting block 45 to automatically reset. One end of the limiting block 45 is fixedly connected to the mounting frame 44, so that the mounting frame 44 and the movable wheels 43 on the mounting frame 44 can be moved through the limiting block 45.

[0037] Please see Figure 3 and Figure 4A guide plate 48 is provided on the limiting seat 41. The guide plate 48 is coaxially arranged with the turntable 42, and a through hole for the welding wire to pass through is opened in the center of the guide plate 48. An annular slide 481 is opened at one end of the guide plate 48 near the turntable 42. The annular slide 481 surrounds the outside of the through hole and is concentric with the through hole. Multiple sector blocks 49 are arranged in a circular array inside the annular slide 481. Each sector block 49 is fixedly connected to the inner wall of the annular slide 481, and there is a gap between two adjacent sector blocks 49. A movable rod 47 is fixedly connected to one end of the limiting block 45 away from the mounting bracket 44. One end of the movable rod 47 extends into the annular slide 481 and can enter the gap. The curvature of the surface of the sector block 49 can change the direction of force transmission, thereby allowing the movable rod 47 to move from the middle of two sector blocks 49 to the top of the sector block 49. When the turntable 42 rotates, the movable rod 47 moves on the surface of the sector block 49 and between the sector blocks 49, thereby driving the limit block 45 to move back and forth along the axial direction of the guide rod 46, so that the movable wheel 43 moves back and forth along the radial direction of the welding wire, making intermittent contact with the welding wire, achieving the hammering effect, and improving the roundness and stress uniformity of the welding wire surface.

[0038] Please see Figure 2 and Figure 5 One end of the pinion 413 is fixedly connected to a reciprocating lead screw 415, and a moving block 416 meshes with the surface of the reciprocating lead screw 415. A drive rod 418 is fixedly connected to the surface of the moving block 416. Correspondingly, a transmission plate 417 is fixedly connected to the guide plate 48, and an inclined slide rail is provided on the transmission plate 417. One end of the drive rod 418 extends into the inclined slide rail and slides in contact with the inner wall of the inclined slide rail. The inclined slide rail restricts the circumferential motion of the drive rod 418, so that when the reciprocating lead screw 415 rotates, it drives the drive rod 418 to move back and forth along its axis through the moving block 416. It is worth noting that an arc-shaped plate 411 is fixedly connected to the limiting seat 41, and an arc-shaped groove is formed on the guide plate 48. One end of the arc-shaped plate 411 is inserted into the arc-shaped groove and slidably connected to the inner wall of the arc-shaped groove. The curvature of the arc-shaped plate 411 is smaller than that of the arc-shaped groove, allowing the arc-shaped groove to rotate at a certain angle on the surface of the arc-shaped plate 411. This angle is adapted to the height of the inclined slide. After the guide plate 48 rotates, the angle of the sector blocks 49 on it will change, allowing the movable rod 47 to enter between two adjacent sector blocks 49 at different angles. This allows the movable wheel 43 to hammer the surface of the welding wire from different angles, resulting in a better effect.

[0039] When the cold continuous rolling device for welding wire production of this utility model is in use, the welding wire is passed through the first roll 2, the second roll 3 and the two movable wheels 43 in the auxiliary processing mechanism 4, as well as through the through holes of the turntable 42 and the guide plate 48.

[0040] During the rolling process, the output of motor 412 drives pinion 413 and reciprocating screw 415 to rotate. Pinion 413 meshes with large gear 414, which in turn drives turntable 42 to rotate. Turntable 42 drives two limit blocks 45 to rotate via guide rod 46. Limit blocks 45 synchronously drive mounting bracket 44 and movable rod 47 fixedly connected to them to rotate. Mounting bracket 44 drives two movable wheels 43 to rotate around the welding wire. At this time, movable rod 47 moves within annular slide rail 481. The surface of movable rod 47 contacts the arc surface of a sector block 49 and moves upward along the arc surface. After moving to the top of sector block 49, it disengages from it and then falls rapidly back under the elastic force of the spring, entering between the two sector blocks 49. At this time, movable wheel 43 moves towards the welding wire and contacts the surface of the welding wire, achieving a hammering effect to improve the roundness and stress uniformity of the welding wire surface.

[0041] When the reciprocating screw 415 rotates, it drives the drive rod 418 to move back and forth along its axis via the moving block 416. The drive rod 418 pushes the transmission plate 417 through the inclined slide, which in turn drives the guide plate 48 to rotate at a certain angle, thereby changing the angle of the sector block 49 in the annular slide 481. This changes the contact angle between the movable wheel 43 and the welding wire, improving the effect of the device on the surface shaping of the welding wire.
