Description

Technical Field

[0001] This utility model relates to the field of disc wire drawing technology, and in particular to a disc wire drawing device. Background Technology

[0002] A disc wire drawing machine is a specialized machine used for processing metal wires. It typically immerses the steel wire workpiece in an oil tank and then spirally winds the lubricated steel wire workpiece around the surface of a disc. The rotating disc drives the steel wire workpiece forward and conveys it into a mold, where the diameter of the steel wire workpiece is reduced through a drawing process.

[0003] Because a layer of lubricating oil film will be absorbed on the surface of the steel wire workpiece after soaking, a rubber scraper is usually installed at the outlet of the oil tank to scrape off the excess lubricating oil on the surface of the steel wire workpiece through elastic contact.

[0004] However, due to its relatively long length, the steel wire workpiece remains in a relaxed state as it moves within the oil tank. This can easily cause the steel wire workpiece to deviate when it comes into contact with the rubber scraper, which in turn can affect the scraping effect of the rubber scraper on the surface of the steel wire workpiece. Utility Model Content

[0005] Therefore, it is necessary to provide a disc wire drawing device to address the problem that keeping the wire workpiece in a relaxed state during movement within the oil tank can easily lead to displacement when the wire workpiece comes into contact with the rubber scraper.

[0006] Includes: a wire drawing table, on the top of which an oil tank is installed; an anti-deviation mechanism, which includes a fixed frame installed on the top of the oil tank, two limiting rings fixedly connected to the bottom of the fixed frame, a ring of limiting rods slidably connected to the inner wall of the limiting rings, a ball bearing rolledly connected to one end of the limiting rods, and a rubber scraper engaged at the lower end of the surface of the fixed frame.

[0007] In one embodiment, a guide frame is fixedly connected to the inner wall of the oil tank, and a filter screen is fixedly connected to the inner wall of the guide frame. The guide frame is used to collect the scraped lubricating oil and guide it into the oil tank, while the filter screen filters the lubricating oil that slides into the oil tank, preventing impurities from flowing into the oil tank with it and reducing the waste of lubricating oil.

[0008] In one embodiment, a positioning frame is slidably connected to the inner wall of the limiting ring, and the surface of the positioning frame is engaged with the inner wall of the limiting rod.

[0009] In one embodiment, a plurality of rubber blocks are fixedly connected to the surface of the positioning frame, and the surface of the rubber blocks is engaged with the inner wall of the limiting rod.

[0010] In one embodiment, a spring is fixedly connected to one end of the limiting rod, and the other end of the spring is fixedly connected to the inner surface of the limiting ring. The elastic force of the spring pushes the limiting rod longitudinally, causing the ball bearings to contact the wire workpiece. The positioning frame and the rubber block cooperate to lock the limiting rod, ensuring that the multiple ball bearings stably limit the movement of the wire workpiece. This, in turn, ensures that the wire workpiece slides stably into the rubber scraper, and that the rubber scraper thoroughly removes excess lubricating oil from the wire workpiece.

[0011] In one embodiment, the limiting ring is a nickel alloy component, the positioning frame is a samarium cobalt magnet component, and the surface of the positioning frame is magnetically attracted to the surface of the limiting ring.

[0012] In one embodiment, two guide rods are fixedly connected to one end of the limiting ring, and the inner wall of the positioning frame is slidably connected to the surface of the guide rods. The guide rods limit the movement of the limiting ring, preventing it from dislodging from the limiting ring during movement.

[0013] In one embodiment, the inner wall of the rubber scraper is threaded with a bolt, the surface of which is threaded to the lower end of the inner wall of the fixing frame. The bolt facilitates the replacement of the rubber scraper on the fixing frame, ensuring the effective oil scraping of the steel wire workpiece. Beneficial effects

[0014] 1. By cooperating with the fixed frame, limiting ring, limiting rod and ball bearing, the moving steel wire workpiece is guided and limited, avoiding the steel wire workpiece from deviating when it comes into contact with the rubber scraper during movement. This ensures that the steel wire workpiece slides stably into the rubber scraper, and the rubber scraper completely removes excess lubricating oil from the steel wire workpiece, thus ensuring the oil scraping effect of the rubber scraper on the surface of the steel wire workpiece.

[0015] 2. The spring's elastic force pushes the limit rod to move longitudinally, causing the balls to contact the steel wire workpiece. The positioning frame and the rubber block work together to lock the limit rod, ensuring that multiple balls stably limit the steel wire workpiece. This, in turn, ensures that the steel wire workpiece slides stably into the rubber scraper, and that the rubber scraper completely removes excess lubricating oil from the steel wire workpiece.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] The following is combined Figures 1-5 This invention describes a disc wire drawing device.

[0026] In one embodiment, a disc wire drawing device includes: a wire drawing table 100, an oil tank 200 mounted on the top of the wire drawing table 100; an anti-deviation mechanism 300, the anti-deviation mechanism 300 including a fixed frame 301 mounted on the top of the oil tank 200, two limiting rings 302 fixedly connected to the bottom of the fixed frame 301, a ring of limiting rods 303 slidably connected to the inner wall of the limiting rings 302, a ball bearing 304 rotatably connected to one end of the limiting rods 303, and a rubber scraper 305 snapped onto the lower end of the surface of the fixed frame 301.

[0027] The oil tank 200 includes an oil frame and a top cover. The top cover is installed on the top of the oil frame by screws, and the oil tank 200 is installed on the top of the drawing table 100 by screws.

[0028] It should be noted that: the disc wire drawing equipment usually consists of a wire drawing table 100, a disc, a wire drawing die, a transmission device, and an oil tank 200.

[0029] When wire drawing is required, a wire feeding device is installed on one side of the wire drawing table 100, and a wire take-up device is installed on the other side of the wire drawing table 100. The wire coil is placed on the wire feeding device, and the wire feeding tension is adjusted by the tension control device to release the wire workpiece at a stable speed. One end of the wire workpiece passes through the oil tank 200 and the anti-deviation mechanism 300 and is wound on the first disc. One end of the wire passes through the first wire drawing die and is wound on the second disc. One end of the wire passes through the second wire drawing die and is installed on the take-up device. The wire is wound according to the predetermined wire drawing process route.

[0030] The disc wire drawing equipment is manually started. The transmission device drives the disc to rotate, which in turn drives the steel wire forward. As the steel wire passes through each drawing die, the diameter of the steel wire decreases as the die aperture gradually decreases, while the length increases, thus achieving diameter reduction stretching. After the steel wire passes through the last stage of drawing, it is conveyed to the take-up device.

[0031] In this embodiment, the steel wire is immersed and moved in the oil tank 200. The three balls 304 on the limiting ring 302 guide and limit the moving steel wire, so that the steel wire slides stably into the rubber scraper 305. The rubber scraper 305 scrapes off the excess lubricating oil on the surface of the steel wire.

[0032] like Figure 2 As shown, a guide frame 306 is fixedly connected to the inner wall of the oil tank 200, and a filter screen 307 is fixedly connected to the inner wall of the guide frame 306.

[0033] In this embodiment, the rubber scraper 305 scrapes off excess lubricating oil from the surface of the steel wire and it slides into the guide frame 306. Because the bottom of the guide frame 306 forms an angle with the water surface, the lubricating oil dripping into the guide frame 306 slides towards the filter screen 307 and flows back into the oil tank 200 after being filtered by the filter screen 307.

[0034] like Figure 3-4As shown, a positioning frame 309 is slidably connected to the inner wall of the limiting ring 302. The surface of the positioning frame 309 is engaged with the inner wall of the limiting rod 303. Several rubber blocks 312 are fixedly connected to the surface of the positioning frame 309. The surfaces of the rubber blocks 312 are engaged with the inner wall of the limiting rod 303. A spring 308 is fixedly connected to the end of the limiting rod 303. The other end of the spring 308 is fixedly connected to the inner surface of the limiting ring 302. The limiting ring 302 is a nickel alloy component, and the positioning frame 309 is a samarium cobalt magnet component. The surface of the positioning frame 309 is magnetically attracted to the surface of the limiting ring 302. Two guide rods 311 are fixedly connected to one end of the limiting ring 302. The inner wall of the positioning frame 309 is slidably connected to the surface of the guide rods 311.

[0035] In this embodiment, the elastic force of the spring 308 pushes the limiting rod 303 to move, causing the ball 304 to abut against the surface of the steel wire, pushing the positioning frame 309 to be stuck in the limiting rod 303 and adsorbed in the limiting ring 302, thereby locking the limiting rod 303.

[0036] like Figure 5 As shown, the inner wall of the rubber scraper 305 is threaded with a bolt 310, and the surface of the bolt 310 is threaded to the lower end of the inner wall of the fixing frame 301.

[0037] The limiting ring 302, limiting rod 303, ball bearing 304, guide frame 306, filter screen 307, spring 308 and bolt 310 are all 17-4PH stainless steel components, which have smoothness, wear resistance and corrosion resistance.

[0038] In this embodiment, when the rubber scraper 305 needs to be replaced, the steel wire is moved away from the rubber scraper 305, the bolt 310 is rotated so that the bolt 310 is moved away from the rubber scraper 305 and the fixing frame 301, and the rubber scraper 305 is pulled down away from the surface of the fixing frame 301. At this time, the new rubber scraper 305 is slid into the lower end of the surface of the fixing frame 301, and the bolt 310 is threaded into the rubber scraper 305 and the fixing frame 301 so that the rubber scraper 305 is installed on the fixing frame 301.

[0039] Working principle: The elastic force of the spring 308 pushes the limiting rod 303 to move, causing the ball bearing 304 to abut against the surface of the steel wire. This pushes the positioning frame 309 to lock inside the limiting rod 303 and be absorbed into the limiting ring 302, thereby locking the limiting rod 303. The steel wire moves while immersed in the oil tank 200. The three ball bearings 304 on the limiting ring 302 guide and limit the moving steel wire, allowing it to slide stably into the rubber scraper 305. The rubber scraper 305 scrapes off excess lubricating oil from the surface of the steel wire, causing the lubricating oil to slide into the guide frame 306. Because the bottom of the guide frame 306 forms an angle with the water surface, the lubricating oil dripping into the guide frame 306 slides towards the filter screen 307, and after being filtered by the filter screen 307, flows back into the oil tank 200.

[0040] It should be noted that the wire drawing table 100, oil tank 200, fixing frame 301 and rubber scraper 305 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the wire drawing table 100 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0041] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
