Technical Field

[0001] This utility model relates to the field of double-headed large-scale pulling machine technology, specifically a pre-treatment mechanism for pulling wire traction. Background Technology

[0002] The wire feeding stand is a crucial step in smoothly pulling the copper rod from the copper rod coil and into the double-head drawing machine. The double-head drawing machine is a commonly used metal processing equipment, primarily used for stretching or extruding metal materials. It consists of two independent drawing heads, capable of simultaneously stretching or extruding two metal wires. The double-head drawing machine is characterized by high efficiency, stability, and reliability, and is widely used in the metal products processing industry.

[0003] In the prior art, after the wire is released by the wire release device, it needs to be pulled by the traction mechanism before entering the double-head drawing machine. The traction mechanism is used to smoothly and appropriately guide the wire output from the wire release device into the subsequent drawing die. However, the existing traction mechanism is generally fixed, which makes it inconvenient to adjust the tension of the wire during traction. Utility Model Content

[0011] By adopting the above technical solution, the conductor can pass over the two tensioning rollers, allowing the tension of the conductor to be adjusted during traction by adjusting the rotation angle of the rotating frame.

[0012] Preferably, both the guide wheel and the tensioning wheel have guide grooves cut into their sides to fit the surface of the conductor.

[0013] By adopting the above technical solution, it is convenient for the wire to pass through the guide wheel and the tensioning wheel.

The slider is embedded in the sliding groove and slidably connected to the support frame. The spring is provided at the bottom end of the slider and is located between the slider and the support frame. A groove is provided at the bottom of the slider to limit the lateral movement of the spring.

[0015] By adopting the above technical solution, the slider can slide vertically up and down along the side of the support frame along the slide groove, and at the same time, the slide rod can be pushed up by the spring.

[0016] Preferably, the traction part also has a locking tooth disposed on the top of the slide bar, the locking tooth having a certain tilt angle, and the locking tooth and the ratchet teeth disposed around the rotating shaft to form a ratchet structure.

[0017] By adopting the above technical solution, the slide bar can be pushed upward by the spring, so that the top of the slide bar engages with the ratchet, making the rotating frame rotate only clockwise.

[0018] Preferably, the traction unit also has a handrail located on the side of the rotating frame away from the support frame and a handle located at the bottom of the slide bar.

[0019] By adopting the above technical solution, it is convenient for operators to adjust the rotation angle of the rotating frame by using the handrail and to pull down the slide bar by holding the handle to make it slide vertically downwards against the elastic force of the spring.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] Please see Figure 1 , Figure 2 and Figure 3 This embodiment provides a technical solution: a wire traction pretreatment mechanism, including a support frame 1, a slide 103, and a traction unit 2.

[0032] Two guide wheels 101 are rotatably mounted on the side of the support frame 1 to guide the direction of the conductor. A traction unit 2 is located on the side of the support frame 1. A rotating frame 201 is rotatably mounted on the side of the support frame 1. A ratchet 203 is provided on the outer side of the rotating frame 201. A tension wheel 205 is rotatably mounted inside the rotating frame 201, and the tension wheel 205 abuts against the conductor. A slide rod 206 is vertically slidably mounted on the side of the support frame 1. The slide rod 206 and the ratchet 203 form a ratchet structure. A spring 210 is provided on the side of the slide rod 206. (The last sentence appears to be incomplete and possibly refers to a different part of the support frame 1.) Figure 3 As shown, without external force, spring 210 will push the top push rod 206 up to... Figure 3 At the position of the spring 210, and within the groove 103 where the spring 210 is located, the spring 210 provides elastic force to push the slide rod 206 to slide vertically upward to unidirectionally restrict the rotation direction of the rotating frame 201. The spring 210 can push the slide rod 206 upward, so that the top of the slide rod 206 engages with the ratchet 203, so that the rotating frame 201 can only rotate clockwise. The wire will pass through the tensioning wheel 205 that is rotated at both ends of the rotating frame 201, so that the tension of the wire during traction can be adjusted by adjusting the rotation angle of the rotating frame 201.

[0033] Example 2

[0034] Please see Figure 4 , Figure 5 and Figure 6 This embodiment provides a technical solution: a wire traction pretreatment mechanism, including a traction unit 2, a rotating frame 201, and a tensioning wheel 205.

[0035] A rotating groove 102 is provided on the side of the support frame 1. A rotating shaft 202 is fixed on the side of the ratchet 203 near the support frame 1. The rotating shaft 202 is embedded in the rotating groove 102 and rotatably connected to the support frame 1, allowing the rotating frame 201 to rotate on the side of the support frame 1 to change its angle. Two tensioning wheels 205 are provided, rotatably positioned at both ends of the rotating frame 201. The two tensioning wheels 205 have a central rotational symmetry structure around the rotation center of the rotating frame 201, allowing the wire to pass through the set... Two tensioning rollers 205 pass over each other, allowing the tension of the wire to be adjusted by changing the rotation angle of the rotating frame 201. Guide grooves conforming to the surface of the wire are cut into the sides of both the guide roller 101 and the tensioning roller 205, facilitating the passage of the wire through them. A sliding groove 103 is provided on the side of the support frame 1. A slider 208 is provided on the side of the slide rod 206 near the support frame 1. The slider 208 is embedded in the sliding groove 103 and slidably connected to the support frame 1. The sliding groove 103 is as follows: Figure 5As shown, the slide groove 103 extends through the support frame 1 on one side, while the other five sides are closed. The two sides of the slider 208 abut against the inner wall of the slide groove 103 to ensure that the spring 210 can only buffer longitudinally and will not wobble left and right. The spring 210 is set at the bottom of the slider 208 and is located between the slider 208 and the support frame 1. The bottom of the slider 208 has a groove to limit the lateral movement of the spring 210, which allows the slider 208 to slide vertically up and down along the side of the support frame 1 along the slide groove 103. At the same time, the spring 210 can push the slide rod 206 to move upward.

[0036] Example 3

[0037] Please see Figure 3 , Figure 5 and Figure 7 This embodiment provides a technical solution: a wire traction pretreatment mechanism, including a traction unit 2, a slide bar 206, and a locking tooth 207.

[0038] A locking tooth 207 is provided at the top of the slide bar 206. The locking tooth 207 has a certain tilt angle. The locking tooth 207 and the ratchet tooth 203 arranged around the rotating shaft 202 form a ratchet structure. The slide bar 206 can be pushed upward by the spring 210, so that the top of the slide bar 206 engages with the ratchet tooth 203, so that the rotating frame 201 can only rotate clockwise. A handrail 204 is provided on the side of the rotating frame 201 away from the support frame 1, and a handle 209 is provided at the bottom of the slide bar 206. The operator can easily adjust the rotation angle of the rotating frame 201 by holding the handrail 204 and pull down the slide bar 206 by holding the handle 209 to make it slide vertically downward against the elastic force of the spring 210.

[0039] Working principle: First, the conductor wire is fed through the feeding device and guided into the rotating frame 201 by the guide wheel 101 set on the support frame 1. It passes through two tensioning wheels 205, and then is smoothly and with appropriate tension guided by another guide wheel 101 into the subsequent drawing die. The sides of both the guide wheel 101 and the tensioning wheel 205 are carved with guide grooves that conform to the surface of the conductor, facilitating the passage of the conductor through them. During the feeding process, the tension of the conductor can be adjusted by adjusting the rotation angle of the rotating frame 201. A locking tooth 207 is provided at the top of the slide rod 206, with a certain tilt angle. The locking tooth 207 engages with the rotating shaft 206. The ratchet teeth 203 surrounding the 02 form a ratchet structure. The spring 210 can push the slide bar 206 upward, so that the top of the slide bar 206 engages with the ratchet teeth 203, making the rotating frame 201 rotate only clockwise. Clockwise rotation of the rotating frame 201 will gradually tighten the wire passing through the guide wheel 101 and the tension wheel 205. When it is necessary to reduce the tension, the slide bar 206 is pulled down by holding the handle 209, so that it overcomes the elastic force of the spring 210 and slides vertically downward, thereby allowing the rotating frame 201 to rotate counterclockwise, thereby reducing the tension of the wire. This allows the tension of the wire during traction to be arbitrarily adjusted, so that the wire can be smoothly and appropriately introduced into the subsequent drawing die.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
