Description

Technical Field

[0001] This utility model relates to the field of steel wire production technology, specifically to a wire feeding device for steel wire drawing. Background Technology

[0002] Steel wire is a slender metal product made by drawing steel to reduce its cross-section and increase its length. The main materials are carbon steel or alloy steel. The different carbon contents in carbon steel result in different properties of the steel wire; for example, high-carbon steel wire has higher strength, while low-carbon steel wire has better toughness. Alloy steel wire, on the other hand, possesses special properties due to the addition of alloying elements (such as manganese and chromium), such as corrosion resistance and wear resistance. Steel wire has high tensile strength and can withstand large tensile forces, making it widely used in applications requiring heavy loads. Through advanced production processes, the diameter, length, and other dimensions of steel wire can be precisely controlled to meet the needs of different users.

[0003] For example, patent CN107720404B discloses a wire feeding device. The wire feeding motor is fixed on the frame and can drive the wire feeding guide wheel to pull the rubber wire into the machine. The push rod of the auxiliary cylinder of the wire feeding guide wheel can drive the wire feeding guide wheel to clamp or release the rubber wire. The first wire pulling fixing plate and the second wire pulling fixing plate are both fixed on the frame. The wire pulling sliding bracket is connected to the slide rod between the first wire pulling fixing plate and the second wire pulling fixing plate. The wire pulling motor is fixed on the first wire pulling fixing plate. The wire pulling motor is connected to the wire pulling sliding bracket through the wire pulling synchronous wheel and the wire pulling synchronous belt, and can drive the wire pulling sliding bracket to slide along the slide rod. The push rod of the wire clamping cylinder is connected to the wire clamping nozzle and can drive the wire clamping nozzle to clamp or release the rubber wire. The push rod of the wire cutting cylinder is connected to the wire cutting nozzle and can drive the wire cutting nozzle to cut and clamp the rubber wire. The wire cutting nozzle is set on the side of the wire feeding guide wheel that feeds out the rubber wire. However, during use, the existing device suffers from insufficient stability of the conveying mechanism, resulting in significant vibration. This causes the friction between the wire feeding wheel assembly and the steel wire surface to fluctuate periodically, making it impossible to provide a continuous and stable driving force for steel wire conveying. Furthermore, the adaptable size range of the conveying device is relatively fixed, lacking a flexible and adjustable clamping distance adjustment mechanism, making it difficult to meet the conveying needs of steel wires with different diameter specifications. This results in significant application limitations when facing diverse production scenarios.

[0004] Therefore, in order to solve this problem, we propose a wire feeding device for wire drawing. Utility Model Content

[0005] The purpose of this utility model is to provide a wire feeding device for steel wire drawing, in order to solve the problems mentioned in the background art. In the process of use, the existing device has insufficient stability of the conveying mechanism, which causes obvious vibration. This results in the friction between the wire feeding wheel set and the surface of the steel wire exhibiting periodic fluctuations, making it impossible to continuously and stably provide driving force for the steel wire conveying. Furthermore, the adaptable size range of the conveying device is relatively fixed, and it lacks a flexible and adjustable clamping distance adjustment mechanism, making it difficult to meet the conveying needs of steel wires of different diameters and specifications. It also has obvious application limitations when facing diverse production scenarios.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wire feeding device for drawing steel wire, comprising a base and a vertical plate fixedly connected to the top of the base, a horizontal plate fixedly connected to the top of the vertical plate, a cylinder fixedly connected to the middle of the top surface of the horizontal plate, a push rod fixedly connected to the output end of the cylinder, the push rod penetrating the horizontal plate, a support plate fixedly connected to the bottom of the push rod, springs evenly fixedly connected to the bottom of the support plate, a slider fixedly connected to the bottom of the springs, a limit assembly fixedly connected to the front outer wall of the slider, the limit assembly comprising a first limit plate fixedly connected to the front outer wall of the slider, a screw rotatably connected to the middle of the first limit plate, and a second limit plate provided on the screw.

[0007] Furthermore, a sliding groove is provided on the front outer wall of the upright plate, and sliding rods are fixedly connected to both sides of the inner wall of the sliding groove.

[0008] Furthermore, guide rods are uniformly fixedly connected to the outer wall of the first limiting plate, and through holes are opened on the second limiting plate, with the guide rods passing through the through holes.

[0009] Furthermore, the slider is located within the slide groove, and the upright plate and the first limiting plate are slidably connected via the slider and the slide groove.

[0010] Furthermore, a servo motor is fixedly connected to the rear outer wall of the left side upright plate at the top of the base, and a rotating shaft is rotatably connected below the slide groove on the upright plate. The output end of the servo motor is fixedly connected to the rotating shaft, a pulley is fixedly connected to the rotating shaft, a belt is sleeved on the pulley, and a limit component is fixedly connected to the front end of the rotating shaft.

[0011] Furthermore, a meter counter is fixedly connected to the right end of the top of the base, and a control terminal is fixedly connected to the top of the meter counter.

[0012] Furthermore, the end of the screw is rotatably connected to the first limiting plate, and the screw is threadedly connected to the second limiting plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the wire feeding device for drawing steel wire adopts a novel structural design, the specific details of which are as follows: (1) The wire feeding device for wire drawing, with the help of the elastic buffering effect of the spring, the inner walls of the first limiting plate and the second limiting plate can always maintain a dynamic contact with the outer surface of the wire, which can effectively suppress the obvious shaking caused by insufficient stability of the conveying mechanism, avoid the periodic fluctuation of the friction force between the wire feeding wheel group and the surface of the wire, and thus ensure that a continuous and stable driving force is provided for the wire conveying. The slider slides precisely along the slide rod in the slide groove, and the slide rod forms a double guide and limit constraint on the slider, which further enhances the structural stability of the device during operation.

[0014] (2) When the screw is rotated, the wire feeding device for wire drawing utilizes the thread transmission principle between the screw and the second limiting plate, and at the same time, with the help of the linear guiding structure formed by the guide rod passing through the through hole of the second limiting plate, the axial distance between the first limiting plate and the second limiting plate can be precisely adjusted, solving the technical bottleneck of fixed clamping distance in traditional devices, and showing excellent working condition adaptability in diverse production scenarios such as wire drawing and coating processing.

[0015] Furthermore, the servo motor drives the rotating shaft to rotate precisely through a coupling. The rotating shaft synchronously drives the coaxially fixed pulley and the surrounding belt to form a transmission system, realizing the fully automated drive of the steel wire conveying. The meter counter adopts the photoelectric pulse counting principle, which can accurately measure the length of the steel wire conveying in real time. Through real-time data feedback, the production process can be visualized and monitored, significantly improving the accuracy of process control and the controllability of production management.

[0018] 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.

[0019] This utility model provides the following technical solution: a wire feeding device for drawing steel wire.

[0020] Example 1: A wire feeding device for drawing steel wire, through components such as a support plate 13, a spring 131, and a slider 14, utilizes the elasticity of the spring 131 to ensure that the inner walls of the first limiting plate 15 and the second limiting plate 161 are always in close contact with the outer surface of the steel wire. This avoids significant vibration caused by insufficient stability of the conveying mechanism, which would lead to periodic fluctuations in the friction between the wire feeding wheel assembly and the steel wire surface, making it impossible to continuously and stably provide driving force for wire feeding. Figure 1 - Figure 5 As shown, a wire feeding device for drawing steel wire includes a base 4 and a vertical plate 1 fixedly connected to the top of the base 4. A horizontal plate 12 is fixedly connected to the top of the vertical plate 1. A cylinder is fixedly connected to the middle of the top surface of the horizontal plate 12. A push rod is fixedly connected to the output end of the cylinder and passes through the horizontal plate 12. A support plate 13 is fixedly connected to the bottom of the push rod. Springs 131 are evenly fixedly connected to the bottom of the support plate 13. A slider 14 is fixedly connected to the bottom of the springs 131. A limit assembly is fixedly connected to the front outer wall of the slider 14. The limit assembly includes a first limit plate 15 fixedly connected to the front outer wall of the slider 14. A screw 16 is rotatably connected to the middle of the disc 15. A second limiting disc 161 is provided on the screw 16. A sliding groove 11 is provided on the front outer wall of the upright plate 1. Sliding rods 111 are fixedly connected to both sides of the inner wall of the sliding groove 11. Guide rods 151 are evenly fixedly connected to the outer wall of the first limiting disc 15. A through hole is provided on the second limiting disc 161, and the guide rods 151 pass through the through hole. The slider 14 is located in the sliding groove 11, and the upright plate 1 and the first limiting disc 15 are slidably connected to the sliding groove 11 through the slider 14. The end of the screw 16 is rotatably connected to the first limiting disc 15, and the screw 16 is threadedly connected to the second limiting disc 161.

[0021] After the cylinder is started, its output push rod drives the support plate 13 to move downward. The support plate 13 drives the lower spring 131 and the slider 14 to move synchronously. The slider 14 slides precisely along the two slide rods 111 in the slide groove 11 of the vertical plate 1, thereby pushing the first limiting plate 15, the screw 16 and the second limiting plate 161 to move downward until the inner wall of the first limiting plate 15 and the second limiting plate 161 contacts the surface of the steel wire. At the same time, after the servo motor is started, it drives the rotating shaft 2 to rotate through the coupling. The limiting component at the front end of the rotating shaft 2 rotates synchronously. The pulley 21 fixed on its outer periphery drives the subsequent transmission components to form a linkage through the belt 22, and finally realizes the forward conveying drive of the steel wire.

[0022] Example 2: Unlike Example 1, this example uses a screw 16 and guide rod 151 to adjust the distance between the first limiting plate 15 and the second limiting plate 161 by rotating the screw 16. This prevents the conveying device from having a fixed range of compatible sizes, lacking a flexible and adjustable clamping distance adjustment mechanism, and failing to meet the conveying needs of steel wires with different diameters, thus limiting its application in diverse production scenarios. Figure 6 As shown, a servo motor is fixedly connected to the rear outer wall of the left side upright plate 1 at the top of the base 4. A rotating shaft 2 is rotatably connected below the slide groove 11 on the upright plate 1. The output end of the servo motor is fixedly connected to the rotating shaft 2. A pulley 21 is fixedly connected to the rotating shaft 2. A belt 22 is sleeved on the pulley 21. A limit component is fixedly connected to the front end of the rotating shaft 2.

[0023] When the diameter of the steel wire changes, the screw 16 is rotated, which drives the second limiting plate 161 to move on the guide rod 151, thereby adjusting the distance between the first limiting plate 15 and the second limiting plate 161 so that they can tightly clamp steel wires of different diameters. The spring 131 is always in a compressed state, using its own elastic force to push the slider 14, keeping the inner wall of the limiting plate in contact with the surface of the steel wire, playing a stabilizing and limiting role during the conveying process and preventing the steel wire from deviating. During the conveying process, the steel wire passes through the meter counter 3, which measures the conveying length of the steel wire in real time and transmits the data to the control terminal. The control terminal can adjust the cylinder pressure, servo motor speed, etc. according to preset parameters, thereby achieving precise control of the steel wire conveying process and ensuring that the conveying length meets production requirements.

[0024] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0025] 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.
