A helical gear is meshed with the outer surface of the helical gear inside the operating box, and a first drive motor is installed on one side of the helical gear. Multiple sets of connecting reels are evenly and movably installed above the discharge platform. The stainless steel wire production equipment described in this utility model, through its helical gear structure, facilitates the wire forming process. Furthermore, the multi-hole design of the connecting joint allows for the processing of different types of steel wire. The steel wire is subjected to balanced force during forming, resulting in high precision and eliminating the need for manual supervision, thus offering better application prospects.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, existing methods for drawing stainless steel heddles typically involve directly using clamps or similar structures to draw the stainless steel heddles to achieve the required product. While this method can draw stainless steel heddles, it suffers from low accuracy and efficiency, and it cannot provide other auxiliary effects during the drawing process, making it impractical.

[0006] Therefore, a stainless steel heddle wire drawing device is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a stainless steel helium wire drawing device that can solve the problems of existing stainless steel helium wire drawing methods, which usually involve directly using clamps or other structures to draw the stainless steel helium wire to achieve the required helium wire product. Although this method can draw stainless steel helium wire, it not only has low accuracy and efficiency during the drawing process, but also cannot achieve other auxiliary effects, resulting in insufficient practicality.

[0018] 1. This application achieves automated and high-precision processing of stainless steel heddle wire drawing by setting up a drawing mechanism and an auxiliary mechanism in coordination. The three sets of tapered drawing dies, together with the motor-driven winding rollers, can perform progressive plastic deformation of stainless steel wire and accurately control the cross-sectional dimensions of the heddle wire, solving the problem of low precision in traditional clamp drawing methods. At the same time, the guide wheel adjusted by the electric push rod ensures that the wire and the die are concentric, improving forming accuracy and production efficiency.

[0019] 2. The auxiliary mechanisms in this application enrich the functionality and improve the practicality of the equipment. The combination of the lubrication box and the oil scraper reduces mold wear and avoids contamination of subsequent processes by the lubricant. The straightening roller and the hydraulic rod work together to correct the bending deformation after drawing and ensure the straightness of the heddle wire. The nylon brush can remove surface burrs and optimize surface quality. The tension sensor and the PLC controller are linked to adjust the winding tension in real time to avoid wire breakage or excessive stretching. The encoder and the cutting knife realize fixed-length cutting to meet the production needs of different length specifications. The above functions are integrated into one unit without the need for additional equipment, which reduces production costs and enhances the overall performance of the equipment.

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.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A stainless steel wire drawing device includes a processing table 3, a drawing mechanism 1 fixedly connected to the top of the processing table 3, and an auxiliary mechanism 2 fixedly connected above the drawing mechanism 1.

[0029] The drawing mechanism 1 includes a pay-off roller 11, an electric push rod 12, a guide wheel 13, three sets of bases 14, a drawing die 15, a mounting frame 16, a motor 17, and a take-up roller 18.

The guide wheel 13 is fixedly connected to the top of the electric push rod 12. The three sets of bases 14 are threadedly connected to the top of the processing table 3. The drawing die 15 is fixedly connected to the top of the base 14. The mounting frame 16 is fixedly connected to the top of the processing table 3. The motor 17 is fixedly connected to the right side of the mounting frame 16. The take-up roller 18 is fixedly connected to the output end of the motor 17.

[0030] In this embodiment: the processing table 3 allows for the installation of structures on the drawing mechanism 1 and auxiliary mechanism 2; the wire feeding roller 11 stores the stainless steel wire; the electric push rod 12 moves the guide wheel 13, which guides the stainless steel wire into the center of the mold along a straight line. The guide wheel 13, in conjunction with the electric push rod 12, allows for fine-tuning of the position to ensure concentricity with the mold hole, adapting to the positioning requirements of stainless steel wires of different specifications; and three sets of bases 14 allow for the installation of the drawing mold 15. The stainless steel wire can be gradually plastically deformed, and the cross-sectional size can be reduced to the target value. The motor 17 can be installed by setting the mounting bracket 16, and the take-up roller 18 can be installed by setting the motor 17. The stainless steel wire can be taken up by setting the take-up roller 18. In this scheme, the three sets of bases 14 are tapered from front to back. The hole of the first set is larger than that of the second set, and the hole of the second set is larger than that of the third set. In this scheme, in order from front to back, the components are: pay-off roller 11, guide wheel 13, three sets of drawing dies 15, three sets of straightening rollers 26, assembly frame 28 and take-up roller 18.

[0031] Specifically, such as Figure 2 , Figure 3 , Figure 4As shown, the auxiliary mechanism 2 includes a lubrication box 21 and an oil scraper 22. The lubrication box 21 is fixedly connected to the top of the first set of bases 14, and the oil scraper 22 is fixedly connected to the rear side of the third set of bases 14.

[0032] Specifically, such as Figure 3 As shown, a fixed frame 23 is fixedly connected to the top of the processing table 3, and a PLC controller 19 is fixedly connected to the right side of the fixed frame 23.

[0033] Specifically, such as Figure 4 , Figure 5 As shown, several straightening rollers 26 are fixedly connected to the left side of the fixed frame 23, and a hydraulic rod 24 is fixedly connected to the top of the fixed frame 23.

[0034] In this embodiment: by setting up a lubrication box 21, lubricant can be sprayed, which can improve the drawing efficiency of stainless steel wire. By setting up an oil scraper 22, oil can be scraped off, making it convenient for subsequent operations on stainless steel wire. By setting up a fixing frame 23, PLC controller 19, straightening roller 26 and hydraulic rod 24 can be installed. In this scheme, straightening roller 26 is set in three groups. Two groups are fixedly connected to the left side of the fixing frame 23 at the bottom, and the remaining group is fixedly connected to the bottom of the fixing plate 25. By setting up PLC controller 19, not only can electric push rod 12, motor 17, oil scraper 22, hydraulic cylinder 4 and hydraulic rod 24 be controlled, but also signals from tension sensor 27 and encoder 6 can be received.

[0035] Specifically, such as Figure 4 , Figure 5 As shown, a fixed plate 25 is fixedly connected to the bottom of the hydraulic rod 24, a straightening roller 26 is fixedly connected to the bottom of the fixed plate 25, and a tension sensor 27 is fixedly connected to the left side of the fixed plate 25.

[0036] Specifically, such as Figure 4 , Figure 5 As shown, an assembly frame 28 is fixedly connected to the top of the processing table 3, and a nylon brush 29 is fixedly connected to the inner wall of the assembly frame 28.

[0037] In this embodiment: the tension sensor 27 and the top set of straightening rollers 26 can be installed by setting the fixing plate 25. The tension sensor 27 can monitor the tension in real time and cooperate with the top set of straightening rollers 26 to adjust the tension. The nylon brush 29 can be installed by setting the assembly frame 28. The nylon brush 29 can remove the tiny burrs on the surface of the stainless steel wire and further optimize the surface finish.

[0038] Specifically, such as Figure 4 , Figure 5 As shown, a hydraulic cylinder 4 is fixedly connected to the top of the processing table 3, and a limit frame 5 is fixedly connected to the bottom of the hydraulic cylinder 4.

[0039] Specifically, such as Figure 4 , Figure 5 As shown, an encoder 6 is fixedly connected to the front side of the limit frame 5, and a cutter 7 is fixedly connected to the bottom of the limit frame 5.

[0040] In this embodiment: the hydraulic cylinder 4 can drive the limit frame 5 to move, the limit frame 5 can install the encoder 6 and the cutter 7, the encoder 6 can record the wire length, and when the set value is reached, the cutter 7 cuts the wire through the action of the hydraulic cylinder 4.

[0041] Working principle: When the user needs to draw stainless steel wire, the stainless steel wire is first released from the unwinding roller 11 and guided to the first set of drawing dies 15 by the guide wheel 13. The electric push rod 12 adjusts the height of the guide wheel 13 to ensure that the wire is aligned with the center of the die. After completion, the motor 17 is powered on and started to drive the winding roller 18 to rotate. At this time, the wire passes through three sets of dies with decreasing apertures in sequence under the action of traction force, and gradually undergoes plastic deformation, reducing the cross-sectional size to the target value. During this process, the lubrication box 21 sprays lubricant synchronously, and the tension sensor 27 monitors the tension in real time and feeds it back to the PLC controller 19 to dynamically adjust the winding speed to maintain stable tension. The drawn wire enters the straightening roller 26 group, and the hydraulic rod 24 adjusts the pressure of the upper straightening roller 26 to correct the bending. After completion, it is polished by the nylon brush 29 to remove surface defects. The encoder 6 records the wire length. When the set value is reached, the hydraulic cylinder 4 drives the cutting knife 7 to cut the wire. The finished product falls into the collection device. Finally, the winding roller 18 simultaneously winds up the uncut wire to ensure the continuity of processing.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
