Description

Technical Field

[0001] This utility model relates to the field of wire drawing and cutting machine technology, and specifically discloses a wire drawing and cutting machine for copper wire solder. Background Technology

[0002] Currently, in the production and processing of solder, the finished solder copper wire needs to be cut to the same length and bundled before it can be sold on the market. The existing cutting is generally done manually, with the operator directly operating the cutting machine using a mold of fixed length. However, the main cutting speed is slow and cannot meet the processing needs. Moreover, the manual cutting cannot guarantee the accuracy in controlling the length, resulting in products of varying lengths and thus failing to guarantee product quality.

[0003] Chinese patent CN204503801U discloses a copper wire solder drawing and cutting machine, including a frame with an upper support arm and a lower support arm. A wire drawing seat is installed at the lower part of the upper support arm. A wire guide block is installed inside the front part of the wire drawing seat. The wire guide block has a tapered inlet and a straightening guide, and is threadedly connected to the front interface of the wire drawing seat. A straightening roller group is installed inside the rear part of the wire drawing seat. A linear track is installed on the lower support arm, and a slide is installed on the linear track. An opening and closing cylinder and a wire drawing clamp driven by the opening and closing cylinder are installed at the upper end of the slide. A cylinder that drives the slide to move left and right is connected to one side of the slide and is installed on the lower support arm. A cutting mechanism for cutting copper wire is also installed on the frame. This utility model improves production efficiency and can ensure the cutting of copper wire to the same length.

[0004] The copper wire solder drawing and cutting machine disclosed in the above document has an adjustable straightening roller group, which makes it impossible to adjust according to the diameter of the copper wire solder.

Therefore, a copper wire solder drawing and cutting machine is needed to solve this problem. Summary of the Invention

The output end of the first servo motor 10 extends to the rear end face of the mounting plate 1 and is fixedly connected to a second gear 11 that meshes with one of the first gears 9.

[0026] In this embodiment: the first servo motor 10 is started, which drives the second gear 11 to rotate, thereby driving one of the first gears 9 to rotate, and then driving the other first gear 9 to rotate synchronously in the opposite direction. The two first gears 9 further drive the two sleeves 4 to rotate relative to each other, and then drive the upper and lower sleeves 4 to rotate synchronously relative to each other through the second connecting rod 7 and the third connecting rod 8. The sleeves 4 further drive the first connecting rod 5 to rotate, and then drive the upper and lower conveying rollers 6 to rotate synchronously relative to each other, clamping and limiting the copper wire solder. This facilitates the limited conveying of copper wire solder of different specifications and is highly practical.

[0027] As a technical optimization of this utility model, the outer wall of the conveying roller 6 is fixedly connected to a first rotating shaft 12 that extends into the interior of the first connecting rod 5 and is rotatably connected to the first connecting rod 5.

One end of the first rotating shaft 12 and the second rotating shaft 14 located inside the first connecting rod 5 is fixedly connected to a pulley 13, and the two pulleys 13 are connected by belt drive.

[0028] In this embodiment: the second rotating shaft 14 is rotated, and the second rotating shaft 14 drives the first rotating shaft 12 to rotate through the belt and pulley 13, which in turn drives the conveying roller 6 to rotate, so as to convey the copper wire solder.

[0029] As a technical optimization of this utility model, the conveying mechanism also includes two first support plates 16 fixedly connected to the rear end face of the mounting plate 1, and a worm gear 17 rotatably connected between the two first support plates 16. A second servo motor 18 with its output end fixedly connected to the worm gear 17 is installed on the outer wall of one of the first support plates 16, and a worm wheel 15 meshing with the worm gear 17 is fixedly connected to the outer wall of the second rotating shaft 14.

[0030] In this embodiment: the second servo motor 18 is started, the second servo motor 18 drives the worm gear 17 to rotate, which in turn drives the worm wheels 15 on the upper and lower sides to rotate synchronously in opposite directions. The worm wheels 15 further drive the second rotating shaft 14 to rotate, which in turn drives the conveying rollers 6 on the upper and lower sides to rotate synchronously in opposite directions, so as to facilitate the conveying of copper wire solder.

[0031] As a technical optimization of this utility model, the cutting mechanism includes two second support plates 19 fixedly connected to the front end face of the mounting plate 1. Electric push rods 20 are installed on the outer walls of the two second support plates 19 respectively, and cutting blades 21 are fixedly connected to the output ends of the two electric push rods 20.

[0032] In this embodiment: two electric actuators 20 are started simultaneously, and the two electric actuators 20 drive two cutting blades 21 to move synchronously relative to each other to cut the copper wire solder.

[0033] As a technical optimization of this utility model, the front end face of the mounting plate 1 is fixedly connected to the limiting block 3, and the outer wall of the limiting block 3 is provided with a limiting hole.

[0034] In this embodiment, the limiting block 3 and the limiting hole facilitate the limiting of the copper wire solder.

[0035] As a technical optimization of this utility model, a controller is provided on the rear end face of the mounting plate 1, and the first servo motor 10, the second servo motor 18 and the electric push rod 20 are all electrically connected to the controller.

[0036] In this embodiment, the controller facilitates the normal operation of the first servo motor 10, the second servo motor 18, and the electric actuator 20.

[0037] The working principle and usage process of this utility model are as follows: In use, copper wire solder is manually drawn through the lead wire block 2. The drawn copper wire solder is located between the upper and lower conveyor rollers 6. Then, the first servo motor 10 is started, driving the second gear 11 to rotate, which in turn drives one of the first gears 9 to rotate, and then drives the other first gear 9 to rotate synchronously in the opposite direction. The two first gears 9 further drive two sleeves 4 to rotate relative to each other, which in turn drives the upper and lower sleeves 4 to rotate synchronously relative to each other via the second connecting rod 7 and the third connecting rod 8. The sleeves 4 further drive the first connecting rod 5 to rotate, which in turn drives the upper and lower conveyor rollers 6 to rotate synchronously relative to each other, clamping the copper wire solder. The device holds the limit position and then starts the second servo motor 18. The second servo motor 18 drives the worm gear 17 to rotate, which in turn drives the worm wheels 15 on both sides to rotate synchronously in opposite directions. The worm wheels 15 further drive the second rotating shaft 14 to rotate, which in turn drives the first rotating shaft 12 to rotate through the belt and pulley 13, which in turn drives the conveying roller 6 to rotate, thus conveying the copper wire solder. The copper wire solder continues to be conveyed to the right through the limit hole of the limit block 3. When the specified length is conveyed, the two electric push rods 20 are started synchronously. The two electric push rods 20 drive the two cutting blades 21 to move synchronously relative to each other, cutting the copper wire solder. This utility model can stably limit and convey copper wire solder of different specifications through the conveying roller 6, which is highly practical.
