Description

Technical Field

[0001] This utility model relates to the technical field of wire processing, and in particular to the technical field of a high-precision wire drawing equipment for metal wires. Background Technology

[0002] Metal wire drawing machines are pre-processing equipment used in the production of standard parts and other metal products. Their purpose is to draw wires produced and transported from steel manufacturers to standard parts and other metal product manufacturers, so that the wires meet the raw material processing requirements for the production of standard parts and other metal products in terms of diameter, roundness, internal metallographic structure, surface finish and straightness.

[0003] Current wire drawing machines are prone to breakage when producing finer products, making it difficult to meet production needs, especially at high speeds. In addition, current wire drawing machines have complex overall structures, are cumbersome to operate, and make it difficult to guarantee product quality.

[0004] To address the problems mentioned above, for example, application number CN201120306786.1 discloses a metal wire drawing machine, including a frame, a wire feeding mechanism on one side of the frame, and a wire take-up mechanism on the frame. The machine is characterized by having a first and second chuck shaft on the frame, with a first and second chuck shaft respectively mounted on the first and second chuck shafts, and a wire drawing die between the first and second chuck shafts. The frame also includes an inner and outer constant-speed wheel shaft, with an inner and outer constant-speed wheel respectively mounted on the inner and outer constant-speed wheel shafts. This application has a reasonable structural design, good operational stability, and high efficiency. The inclusion of inner and outer constant-speed wheels effectively ensures high-speed and smooth operation of the wire drawing machine, resulting in high-quality wire drawing that will not break even when processing finer products, and allows for convenient adjustment.

[0005] Although the aforementioned patent can effectively ensure the high-speed and smooth operation of this wire drawing machine through the inner and outer constant speed wheels, the inner and outer constant speed wheels are noisy during high-speed rotation, are not easy to move, and are not conducive to people's use. In addition, they can only draw wires of the same specification, which brings certain adverse effects to the user's experience.

[0006] To address the problems mentioned above, for example, application number CN202020686768.X discloses a metal wire drawing device, including a drawing device body. A motor noise reduction device is provided on the lower outer surface of the drawing device body, and a movable base plate is provided on the lower outer surface of the motor noise reduction device. An adjusting rod is provided on the upper end of the drawing device body, and a multi-specification drive shaft is provided on the upper end of the adjusting rod. A top plate is provided on the upper end of the multi-specification drive shaft, and a fixing frame is provided on one side of the multi-specification drive shaft. The designed motor noise reduction device reduces motor noise, extends motor lifespan, and improves the overall stability of the device. The multi-specification drive shaft allows the device to draw two different specifications of wire, improving the quality and performance of the device. The designed fixing block ensures a tighter connection of the drive shafts, reducing the risk of damage.

[0007] However, the aforementioned patents still have the following drawbacks: When using a wire drawing machine, the surface of the metal wire needs to be lubricated. However, the wire drawing machine with the above structure lacks a pre-treatment device, which makes it easy for the metal wire to crack or even break due to insufficient lubrication, resulting in a high defect rate. Summary of the Invention

[0008] The purpose of this invention is to solve the problems in the prior art and to propose a high-precision wire drawing device for metal wires, which can pre-clean the metal wires to ensure that the metal wires are in full contact with the drawing oil, thereby ensuring the stretching effect and improving the stretching accuracy and quality.

[0009] To achieve the above objectives, this utility model proposes a high-precision wire drawing device for metal wires, comprising a housing, limiting cylinders, partitions, a pre-cleaning assembly, a fixed bracket, an upper support rod, a lower support rod, a fixed plate, a cleaning sponge, and guide rollers. Limiting cylinders are installed on both the front and rear side walls of the housing. A partition is installed inside the housing, and a pre-cleaning assembly is installed between the partition and the inner side wall of the front end of the housing. The pre-cleaning assembly includes a fixed bracket, an upper support rod, a lower support rod, a fixed plate, and a cleaning sponge. The fixed bracket is installed on the inner side wall of the housing. An upper support rod is vertically installed on the upper inner wall of the fixed bracket, and a lower support rod is vertically installed on the lower inner wall of the fixed bracket. A fixed plate is installed at the adjacent ends of the upper and lower support rods, and a cleaning sponge is adhered to the inner wall of each fixed plate. Three guide rollers are installed between the partition and the inner side wall of the rear end of the housing.

[0010] Preferably, the partition plate has a limiting hole, which corresponds to the limiting cylinder at the front end of the box.

[0011] Preferably, both fixing plates are semi-circular in structure, and the fixing plates are fitted together to form a circle for the wire to pass through, and the circle formed by the fixing plates corresponds to the limiting cylinder at the front end of the box.

[0012] Preferably, the guide roller is rotatably mounted inside the housing via bearings, and the three guide rollers form a V-shaped structure, with one of the guide rollers located below the other two guide rollers.

[0013] Preferably, the tank is equipped with an oil pump and an oil storage tank on top. The input end of the oil pump is connected to the inside of the tank through an oil pumping pipe, and the output end of the oil pump is connected to the oil storage tank through an oil outlet pipe. An oil delivery pipe is connected to the oil storage tank, and the oil outlet end of the oil delivery pipe passes through the inside of the tank and is connected to the limiting cylinder at the rear end. A control valve is also provided on the oil delivery pipe.

[0014] Preferably, an oil outlet is provided below the limiting cylinder at the rear end of the housing.

[0015] Preferably, the rear end of the housing is provided with a wire drawing mechanism, which includes two mounting plates, a winding roller shaft and a rotating motor. The mounting plates are symmetrically arranged at the rear end of the housing, and the winding roller shaft is rotated between the mounting plates. The rotating motor is installed on the side wall of one of the mounting plates, and the output shaft of the rotating motor passes through the side wall of the mounting plate and is connected to the winding roller shaft.

[0016] The beneficial effects of this utility model are: 1. By adding a pre-cleaning component, when the metal wire passes through the limiting cylinder at the front end of the box and then passes between the two fixing plates, the cleaning sponge can remove the metal debris remaining on the surface of the metal wire when it passes between the two fixing plates, thus ensuring the subsequent wire drawing effect and improving the wire drawing accuracy and quality. 2. By adding an oil pump and an oil storage tank, this utility model allows the oil pump to extract the drawing oil from inside the tank after the metal wire passes through the limiting cylinder at the rear end of the tank. The oil pump then delivers the drawing oil to the oil storage tank through the oil outlet pipe. Subsequently, the control valve is opened, allowing the drawing oil in the oil storage tank to enter the limiting cylinder at the rear end of the tank through the oil delivery pipe. This allows the drawing oil to come into contact with the surface of the metal wire inside the limiting cylinder again for re-lubrication, thereby further ensuring the drawing effect of the wire and improving the drawing precision and quality of the metal wire.

Detailed Implementation

[0018] See Figures 1 to 4 This utility model discloses a high-precision wire drawing device for metal wire, comprising a housing 1, a limiting cylinder 2, a partition 3, a pre-cleaning component 4, a fixed bracket 401, an upper support rod 402, a lower support rod 403, a fixed plate 404, a cleaning sponge 405, and a guide roller 5; the limiting cylinder 2 is installed on both the front and rear side walls of the housing 1, the partition 3 is installed inside the housing 1, and the pre-cleaning component 4 is installed between the partition 3 and the inner side wall of the front end of the housing 1; the pre-cleaning component 4 includes ... The enclosure includes a rod 403, a fixing plate 404, and a cleaning sponge 405. The fixing bracket 401 is installed on the inner wall of the housing 1. An upper support rod 402 is vertically installed on the upper inner wall of the fixing bracket 401, and a lower support rod 403 is vertically installed on the lower inner wall of the fixing bracket 401. A fixing plate 404 is installed at the end of the upper support rod 402 and the lower support rod 403 that are close to each other. A cleaning sponge 405 is adhered to the inner wall of the fixing plate 404. Three guide rollers 5 are installed between the partition 3 and the inner wall of the rear end of the housing 1.

[0019] When the metal wire passes through the limiting cylinder 2 at the front end of the housing 1 and then between the two fixing plates 404, the cleaning sponge 405 is attached to the inner wall of both fixing plates 404. Therefore, when the metal wire passes between the two fixing plates 404, the cleaning sponge 405 can remove the metal debris remaining on the surface of the metal wire, thereby ensuring the subsequent wire drawing effect and improving the wire drawing accuracy and quality. It should be noted that a wire drawing die (not shown in the figure) is installed in the limiting cylinder 2 of the housing 1 in this application. The wire drawing die is prior art, so it will not be described in this application. The wire drawing die is used to improve the wire drawing quality.

[0020] See Figure 2 The partition 3 has a limiting hole 301, which corresponds to the limiting cylinder 2 at the front end of the box 1. When the metal wire passes through the two fixing plates 404, it passes through the limiting cylinder 2.

[0021] See Figure 3Both fixing plates 404 are semi-circular in structure. The fixing plates 404 are attached to each other to form a circle through which the wire passes. The circle formed by the fixing plates 404 corresponds to the limiting cylinder 2 at the front end of the housing 1. In this application, the diameter of the circle formed by the two fixing plates 404 is slightly larger than the diameter of the metal wire. When the cleaning sponge 405 is attached to the fixing plates 404, the diameter of the circle is smaller than the diameter of the metal wire. Therefore, the cleaning sponge 405 can adhere to the outer wall of the metal wire and remove the metal debris remaining on the surface of the metal wire.

[0022] See Figure 2 The guide roller 5 is rotatably mounted inside the housing 1 via bearings. The three guide rollers 5 form a V-shaped structure, with one guide roller 5 located below the other two guide rollers 5, thus enabling it to come into full contact with the drawing oil and increasing the contact time.

[0023] See Figure 1 and Figure 2 An oil pump 6 and an oil storage tank 7 are provided on the top of the housing 1. The input end of the oil pump 6 is connected to the inside of the housing 1 through an oil extraction pipe 601, and the output end of the oil pump 6 is connected to the oil storage tank 7 through an oil outlet pipe 602. An oil delivery pipe 701 is connected to the oil storage tank 7. The oil outlet end of the oil delivery pipe 701 passes through the inside of the housing 1 and is connected to the rear limiting cylinder 2. A control valve is provided on the oil delivery pipe 701.

[0024] See Figure 4 An oil outlet 8 is provided below the limiting cylinder 2 at the rear end of the housing 1. When the drawing oil enters the limiting cylinder 2 and comes into contact with the metal wire, the drawing oil flows back into the housing 1 through the oil outlet 8, thus being recycled and avoiding waste of resources. At the same time, the amount of drawing oil is controlled by a control valve.

[0025] See Figure 1 The rear end of the housing 1 is provided with a wire drawing mechanism, which includes two mounting plates 9, a winding roller shaft 10 and a rotating motor 11. The mounting plates 9 are symmetrically arranged at the rear end of the housing 1, and the winding roller shaft 10 is rotatably arranged between the mounting plates 9. The rotating motor 11 is installed on the side wall of one of the mounting plates 9. The output shaft of the rotating motor 11 passes through the side wall of the mounting plate 9 and is connected to the winding roller shaft 10. When the wire passes through the limiting cylinder 2 at the rear end of the housing 1 and is fixed on the winding roller shaft 10, the output shaft is driven to rotate by the rotating motor 11, thereby driving the winding roller shaft 10 to rotate, and thus driving the wire to start drawing.

[0026] The working process of this utility model: In the operation of this high-precision metal wire drawing equipment, an appropriate amount of drawing oil is first injected into the housing 1, ensuring that the lowest guide roller 5 is completely submerged in the oil. Then, one end of the metal wire is inserted through the limiting cylinder 2 at the front of the housing 1 and passes between two fixing plates 404. A cleaning sponge 405 removes any metal debris remaining on the surface of the wire. The wire then passes through the limiting hole 301 and sequentially around the three guide rollers 5, exiting through the limiting cylinder 2 at the rear of the housing 1. Finally, the wire is wound onto the winding roller shaft 10 and fixed. The output shaft is driven to rotate by the rotating motor 11, which in turn rotates the winding roller shaft 10, thus initiating the wire drawing process. The guide roller 5 is set so that the metal wire can follow a V-shaped path inside the housing 1, and the metal wire can come into contact with the drawing oil from all directions, increasing the contact time. Then, the oil pump 6 is started by the external controller (not shown in the figure). The oil pump 6 extracts the drawing oil from inside the housing 1 and delivers the drawing oil to the oil storage tank 7 through the oil outlet pipe 602. Then, the control valve is opened so that the drawing oil in the oil storage tank 7 enters the limiting cylinder 2 at the rear end of the housing 1 through the oil delivery pipe 701, so that the drawing oil comes into contact with the surface of the metal wire in the limiting cylinder 2 again for lubrication, thereby further ensuring the drawing effect of the wire and improving the drawing accuracy and quality of the metal wire.

[0027] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0028] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
