Description

Technical Field

[0001] This utility model belongs to the field of metal wire stretching and preparation technology, and specifically relates to a surface treatment device for metal wire stretching and preparation. Background Technology

[0002] Metal wire drawing is a process that uses a die to apply tension to a metal wire, reducing its cross-section and extending its length to obtain a wire with a specific diameter, precision, and mechanical properties. It is widely used in electronics, machinery, construction, and other fields, and can give the wire a uniform diameter, higher strength, and better surface quality.

[0003] In the metal wire drawing process, the drawing step has stringent requirements for the surface quality of the wire. During storage and preliminary processing, metal wires are prone to defects such as oxide scale, rust, and scratches. If drawn directly, these defects will exacerbate die wear, cause uneven drawing resistance, and result in large diameter deviations, surface scratches, and even breakage after drawing. Furthermore, residual impurities may become embedded within the wire, reducing its mechanical properties and product precision.

[0004] Polishing machines can precisely remove oxide layers, rust spots, and minor defects from the surface of wires through physical grinding, optimizing surface roughness. After polishing, the wire surface is smoother and more uniform, which can effectively reduce frictional loss during stretching, extend die life, and ensure the diameter accuracy and surface quality of the wire after stretching. This lays a solid foundation for subsequent processing (such as precision electronic wires and high-end spring manufacturing), making it a key surface pretreatment step before stretching metal wires.

[0005] Existing wire polishing machines require manual intervention at the feed and discharge ports to guide and limit the wires being processed. This not only increases labor costs but also poses safety hazards, as workers near the polishing area may be injured by flying waste. Utility Model Content

[0006] The purpose of this invention is to provide a surface treatment device for metal wire stretching preparation, which aims to solve the problem that existing wire polishing machines require manual intervention at the feed and discharge ports to guide and limit the processed wire during the processing. This method not only increases labor costs but also poses safety hazards, such as causing workers near the polishing position to be scratched by flying waste.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a surface treatment device for preparing metal wire by stretching, comprising a polishing machine body, a polishing assembly mounted on the top of the polishing machine body, a fixed frame connected to the surface of the operating table of the polishing machine body, a motor mounted on the top surface of the fixed frame, a ball screw connected to the output end surface of the motor, the bottom surface of the ball screw sleeved in a bearing connected to the bottom of the fixed frame, a threaded block threadedly connected to the surface of the ball screw, an adjusting plate connected to the other side surface of the threaded block, a slider connected to the other side surface of the adjusting plate, the slider slidably connected to a slide rod surface connected to the inner wall of a fixed seat, the bottom surface of the fixed seat connected to the surface of the operating table of the polishing machine body, a servo motor mounted on the top surface of the adjusting plate, a pusher plate connected to the output end surface of the servo motor, the other side surface of the pusher plate sleeved in a bearing on the surface of a bearing frame, the bottom surface of the bearing frame connected to the top of the adjusting plate, limit frames connected to the top of the adjusting plate on both sides of the pusher plate, and a control panel mounted on the surface of the polishing machine body.

[0009] As a preferred embodiment of the surface treatment device for preparing metal wire stretching according to this utility model, the surface of the slider is provided with a circular through groove, and the shape and size of the through groove are adapted to the slider rod.

[0010] As a preferred embodiment of the surface treatment device for preparing metal wire stretching according to this utility model, the two sets of fixing frames, adjusting plates and fixing seats are respectively connected to the inlet and outlet of the polishing assembly on both sides.

[0011] In a preferred embodiment of the surface treatment device for preparing metal wire stretching according to this utility model, the limiting frame and the polishing tube on the surface of the polishing component are at the same horizontal height, and the limiting frame is an arched frame.

[0012] As a preferred embodiment of the surface treatment device for preparing metal wire stretching according to this utility model, the pusher plate is an integral structure consisting of two conical structures connected together.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 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.

[0022] Please see Figures 1-4This utility model provides the following technical solution: a surface treatment device for preparing metal wire stretching, comprising a polishing machine body 1, a polishing assembly 2 mounted on the top of the polishing machine body 1, a fixed frame 3 connected to the surface of the operating table of the polishing machine body 1, a motor 4 mounted on the top surface of the fixed frame 3, a ball screw 5 connected to the output end surface of the motor 4, the bottom surface of the ball screw 5 sleeved in a bearing connected to the bottom of the fixed frame 3, a threaded block 6 threadedly connected to the surface of the ball screw 5, an adjusting plate 7 connected to the other side surface of the threaded block 6, a slider 8 connected to the other side surface of the adjusting plate 7, the surface of the slider 8 slidably connected to the surface of a slide rod 9 connected to the inner wall of a fixed seat 10, and the bottom surface of the fixed seat 10 connected to the operating table of the polishing machine body 1. A servo motor 11 is mounted on the top surface of the adjustment plate 7 on the worktable surface. The output end of the servo motor 11 is connected to the push plate 12. The other side of the push plate 12 is fitted into the bearing on the surface of the bearing frame 13. The bottom surface of the bearing frame 13 is connected to the top of the adjustment plate 7. The top of the adjustment plate 7 is connected to the limiting frame 14 on both sides of the push plate 12. A control panel 15 is mounted on the surface of the polishing machine body 1. In this design, the polishing machine body 1 and the polishing component 2 constitute the main body of the wire polishing machine. A large number of related components are set in the main body of the wire polishing machine. Since they are existing technologies and the core content of this technical solution is irrelevant to them, they will not be described in detail in this technical solution.

[0023] In use: The main body of the wire polishing machine utilizes the polishing wheel within the polishing assembly 2. Through a specific transmission structure, the polishing wheel revolves around the wire while simultaneously rotating at high speed. As the metal wire passes through the center of the equipment, the friction and micro-cutting action between the polishing wheel and the wire surface removes oxide scale, black scale, defects, etc. from the wire surface.

[0024] Preferably, a rectangular groove is provided on one side of the fixing frame 3, and the shape and size of the groove are adapted to the threaded block 6.

[0025] In practical use, the threaded block 6 can be moved vertically on the surface of the fixed frame 3 through the sliding groove on one side of the fixed frame 3 to adjust the height of the adjusting plate 7, thereby ensuring that the wire fed from the top of the adjusting plate 7 enters the polishing assembly 2 smoothly and accurately for polishing.

[0026] Preferably, a circular through groove is formed on the surface of the slider 8, and the shape and size of the through groove are adapted to the slider 9.

[0027] In practical use, the circular through groove on the surface of the slider 8 allows it to slide vertically onto the slider 9, thereby moving together with the adjusting plate 7 under the action of the threaded block 6, providing stable support for the adjusting plate 7 which adjusts the height.

[0028] Preferably, two sets of fixing frames 3, adjusting plates 7 and fixing seats 10 are respectively connected to the inlet and outlet of the polishing assembly 2.

[0029] In practical use, the two sets of fixed frames 3, adjusting plates 7 and fixed seats 10 on both sides of the polishing component 2 cooperate to automatically push the wire to be processed through the cooperation of the pusher plate 12 and the limiting frame 14 fixed on it. At the same time, the pusher plate 12 and the limiting frame 14 on the discharge side of the polishing component 2 assist in the movement of the wire during processing to ensure its conveying efficiency.

[0030] Preferably, the limiting frame 14 and the polishing tube on the surface of the polishing component 2 are at the same horizontal height, and the limiting frame 14 is an arched frame.

[0031] In practical use, the through groove on the inner wall of the limiting frame 14 and the polishing component 2 are at the same level, so that the height can be adjusted according to the wire type to limit the conveyed wire.

[0032] Preferably, the pusher plate 12 is an integral structure consisting of two connected conical structures.

[0033] In practical use, the groove formed between the two conical structures on the surface of the pusher plate 12 is used to limit the transmission range on both sides of the conveyed wire during conveying, so as to avoid its position deviation during conveying.

[0034] Working principle: Before stretching the metal wire, the polishing machine body 1 is used to remove oxide scale, scratches, and other defects from the wire surface. When polishing is required, the parameters are first set through the control panel 15 according to the type of wire to be polished, so that the motor 4 can be started to rotate, thereby driving the connected ball screw 5 to rotate together. This allows the threaded block 6, which is threaded onto the ball screw 5, to slide and adjust its height on the motor 4. At the same time, the slider 8 on the other side of the connected adjustment plate 7 also slides on the slide rod 9, so that the moving adjustment plate 7 can be stably and vertically moved to the feeding height that meets the requirements of the wire to be processed. At this time, the wire to be processed is passed through the limiting frame 14 located at one end of the feed port of the polishing component 2. Then, the bottom of the wire abuts against the groove formed between the two conical structures on the top of the pusher plate 12. The pusher plate 12 is made of rubber and has a threaded structure on its surface, which increases the friction between the contact surface with the wire, making it easier to push the wire to move. The wire then passes through the limiting frame 14 on the other side and finally inserts into the polishing tube on the surface of the polishing assembly 2. The above operation is repeated to pass the wire through the polishing tube on the surface of the polishing assembly 2 and then abut against the inner wall of the limiting frame 14 on the other side. At this time, the polishing machine body 1 and servo motor 11 can be started. While the polishing tube on the surface of the polishing assembly 2 rotates to polish the surface of the sleeved wire, the pusher plates 12 on both sides of the polishing assembly 2 rotate towards the discharge port of the polishing assembly 2 under the drive of the servo motor 11, thereby driving the wire on the top of the pusher plate 12 to automatically feed, so as to improve the processing efficiency. At the same time, while the wire on the top of the pusher plate 12 is fed, its top abuts against the inner wall of the limiting frame 14. The movement range of the wire is limited by the cooperation of the pusher plate 12 and the limiting frame 14, so that it can smoothly enter the polishing tube on the surface of the polishing assembly 2 for processing, so as to ensure that the surface of the wire is polished evenly. In this design scheme, the control panel 15, motor 4 and servo motor 11 are electrically connected and connected to an external power supply.

[0035] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
