Description

Technical Field

[0001] This application relates to the technical field of wire drawing machines, and more particularly to a wire drawing machine for solder wire. Background Technology

[0002] A wire drawing machine, also known as a wire drawing machine or wire drawing machine, is a type of mechanical equipment widely used in industrial applications. It is mainly used to transform thick metal wires into thinner wires through a drawing process.

[0003] In existing technologies, wire drawing machines are mostly used for drawing titanium wire and nickel wire. Compared to solder wire, the outer tin is softer and the inner flux is harder. When the material is fed into the coil, it is easy to swing, twist and bend, making it easy to break in the feed tube. Summary of the Invention

[0004] In order to allow solder wire to pass completely through the feed tube, this application provides a solder wire drawing machine.

[0005] A solder wire drawing machine includes a housing, an inlet pipe on the side wall of the housing, and a mounting plate on the housing.

[0006] The coiling mechanism includes a swing rod rotatably connected to the side wall of the housing, and a guide ring is provided at the end of the swing rod. Solder wire passes through the guide ring and extends into the feed tube.

[0007] The straightening mechanism includes a support plate set on the side wall of the housing. Several straightening wheels are rotatably connected to the support plate. The solder wire passes through the several straightening wheels and extends into the feed tube. The straightening wheels abut against the solder wire.

[0008] By adopting the above technical solution, the solder wire coil passes through the guide ring, and the coil is pulled by the swing of the swing rod to prevent the solder wire entering from the feed tube from coiling up, which would cause the solder wire to break. In addition, by using several staggered straightening rollers, the solder wire is initially straightened before entering the feed tube, which can reduce the wear between the solder wire and the feed tube, and allow the solder wire to pass through the feed tube intact.

[0009] Optionally, the winding mechanism also includes a servo motor mounted on the housing, with a rotating disk rotatably connected to the end of the servo motor's power rod. A push rod is mounted on the rotating disk, and the push rod is rotatably connected to the end of the swing rod away from the guide ring.

[0010] By adopting the above technical solution, the servo motor drives the rotating disk to rotate, thereby causing the push rod to move radially along the center of the rotating disk and push the swing rod to swing.

[0011] Optionally, a fixing rod is provided on the outer casing, and a rotating block is rotatably connected to the end of the fixing rod, with the swing rod passing through the rotating block.

[0012] By adopting the above technical solution, the swing arm swings around the fixed rod as the center.

[0013] Optionally, a guide bend is provided at the end of the swing arm away from the servo motor, and the guide ring is rotatably connected to the outer end of the guide bend.

[0014] By adopting the above technical solution, the distance between the solder wire and the guide ring is reduced by the guide bend, and the rotation angle of the guide ring is increased by the rotating connection of the guide ring, so as to reduce the wear of the solder wire and the guide ring.

[0015] Optionally, the straightening mechanism also includes a limiting rod rotatably connected to the support plate. The surface of the limiting rod is recessed towards the center, and the cross-section of the recessed surface of the limiting rod is arc-shaped, with the recessed surface abutting against the solder wire.

[0016] By adopting the above technical solution, the arc-shaped concave surface reduces the wear of the solder wire when it slides back and forth on its surface, while limiting the range of the solder wire's sliding.

[0017] Optionally, the support plate is provided with several positioning rods, which are located between the straightening wheel and the limiting rod. Solder wire is passed between adjacent positioning rods, and the side wall of the positioning rod abuts against the solder wire.

[0018] By adopting the above technical solution, two adjacent positioning rods clamp the solder wire to prevent the solder wire from swinging after entering the straightening wheel.

[0019] Optionally, a "Z"-shaped adjusting rod is provided between the positioning rod and the straightening wheel on the support plate. One end of the adjusting rod passes through the support plate and is rotatably connected to the support plate, while the other end of the adjusting rod contacts the solder wire.

[0020] By adopting the above technical solution, the tension between the other end of the adjusting rod and the solder wire can be controlled by rotating one end of the adjusting rod, thus preventing the solder wire from breaking due to excessive tension.

[0021] Optionally, a feed wheel is provided on the outer casing below the feed tube. The feed wheel is used to adjust the position of the solder wire passing through the feed tube.

[0022] By adopting the above technical solution, the solder wire passes through the feed tube via the feed roller, which can reduce the wear between the solder wire and the feed tube.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The solder wire roll is connected and pulled by the swinging rod to prevent the solder wire entering from the feed tube from coiling. Then, several staggered straightening rollers are used to initially straighten the solder wire before it enters the feed tube to prevent it from breaking at the feed tube.

[0025] 2. It can reduce wear on the solder wire before it enters the wire drawing machine and increase the integrity of the surface tin metal. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail below.

[0031] A wire drawing machine for solder wire, as described in the following figure Figure 1 It includes a housing 1, a feed pipe 2 fixedly connected to the side wall of the housing 1, and a winding mechanism 3 for swinging out the solder wire roll and a straightening mechanism 4 for initially straightening the solder wire and feeding it into the feed pipe 2 on the housing 1 on the same side as the feed pipe 2.

[0032] Reference Figure 1 , Figure 2 The winding mechanism 3 includes a servo motor 301 fixedly connected to the upper surface of the housing 1, and a rotating disk 302 fixedly connected to the power rod of the servo motor 301. A fixing block 303 is fixedly connected to the rotating disk 302, and the fixing block 303 rotates radially along the power rod. One end of a push rod 304 is rotatably connected to the fixing block 303.

[0033] The other end of the push rod 304 is rotatably connected to a rotating shaft. A spherical rotating block is fixedly connected to the rotating shaft away from the push plate 304. The spherical rotating block extends into the sliding plate 305 and is rotatably connected to the sliding plate 305.

[0034] A fixed rod 306 is fixedly connected to the side wall of the outer casing 1. A rotating block 6 is rotatably connected to the upper end face of the fixed rod 306. A swing rod 307 is fixedly fixed inside the rotating block 6. The side of the sliding plate 305 away from the push rod 304 is fixedly connected to the swing rod 307.

[0035] Reference Figure 1 The swing rod 307 is fixedly connected to a downwardly curved guide elbow 308 at the end away from the push rod 304. The end of the guide elbow 308 is rotatably connected to a guide ring 309, and the tin wire is wound inside the guide ring 309.

[0036] Reference Figure 1 The straightening mechanism 4 includes a support plate 401 fixedly connected to the outer casing 1. A horizontally placed limiting rod 402 is rotatably connected to the side of the support plate 401 away from the outer casing 1. The middle section of the limiting rod 402 is concave towards the center, and the cross-section of the concave surface is arc-shaped. The two sides of the concave surface smoothly transition to the non-concave surface of the limiting rod 402. Under the action of the swing rod 307, the solder wire slides back and forth along the surface of the concave surface.

[0037] A positioning block 7 is fixedly connected between the support plate 401 and the limiting rod 402 and the outer shell 1. Two vertically arranged positioning rods 403 are rotatably connected to the positioning block 7. A gap is left between the two positioning rods 403. A tin wire is wound through the gap and abuts against the side wall of the two positioning rods 403.

[0038] A Z-shaped adjusting rod 404 is rotatably connected to the support plate 401 between the positioning block 7 and the outer shell 1. One end of the adjusting rod 404 passes through the support plate 401 and is fixedly connected to a handle 8. Rotating the handle 8 drives the other end of the adjusting rod 404 to rotate axially. The other end of the adjusting rod 404 is provided with a recess, through which a solder wire passes and abuts against the surface of the recess.

[0039] Three straightening wheels 405 are rotatably connected on the support plate 401 between the adjusting rod 404 and the outer shell 1. The three straightening wheels 405 are arranged in a staggered manner on both sides of the normal line passing through the center of the feed tube 2. The solder wire is gradually straightened after passing through the three straightening wheels 405 in sequence.

[0040] Reference Figure 3 A fixing bracket 9 is fixedly connected to the side wall of the outer casing 1 below the feed pipe 2. The fixing bracket has a mounting groove 10, and adjusting plates 11 are provided on the two opposite inner walls of the mounting groove 10. The adjusting plates 11 are rotatably connected to the fixing bracket 9 by bolts, and the adjusting plates 11 can rotate along the bolt axis. A feed wheel 5 is rotatably connected between the two adjusting plates 11. The solder wire passes through the feed wheel 5 and extends into the feed pipe 2.

[0041] The implementation principle of this application embodiment is as follows: the servo motor 301 drives the rotating disk 302 to rotate. After the rotating disk 302 rotates, it pushes the sliding plate 305 to slide closer to or further away from the swing rod 307, thereby causing the sliding plate 305 to push the swing rod 307. At the same time, the swing rod 307 uses the fixed block 303 as a fulcrum, thereby causing the guide elbow 308 to swing.

[0042] The solder wire coil passes through the guide ring 309, and is pulled out by the swinging of the swinging rod 307. After being pulled out, the solder wire passes through the limiting rod 402, and slides on the arc-shaped concave surface of the limiting rod 402 to reduce the amplitude of the solder wire's swing. It then extends into the gap between the two positioning rods 403, thereby fixing the solder wire to prevent it from swinging or shifting.

[0043] Secondly, the solder wire is then threaded through the adjusting rod 404. Rotating the adjusting rod 404 adjusts the tension of the solder wire as it enters the straightening roller 405. The straightening roller 405 then initially straightens the solder wire, ensuring its integrity during this initial straightening process. Finally, the solder wire extends into the feed tube 2 through the feed roller 5. The height of the feed roller 5 can be adjusted by turning the bolt to accommodate various sizes of solder wire.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
