Description

Technical Field

[0001] The present invention relates to the technical field of wire drawing machines, and particularly to a wire drawing machine cooling device with rust prevention and scale removal functions. Background Art

[0002] A wire drawing machine is a mechanical device widely used in industrial production. It is mainly used to reduce the diameter and increase the length of metal wire rods (such as copper wire, aluminum wire, steel wire, etc.) through a drawing process, while improving the mechanical properties and surface quality of the wire rods. During the drawing process, the wire rod passes through a series of dies (drawing dies), and the aperture of each die gradually decreases. The wire rod passes through the die aperture under the action of tensile force, thereby achieving a decrease in diameter and an increase in length.

[0003] In the patent with the publication number CN118060356B, a steel wire drawing machine is disclosed, which includes a guiding assembly for guiding the steel wire and a winding assembly for providing tensile force. It also includes a first forming mechanism, a second forming mechanism for forming the steel wire, and an adjusting mechanism for driving the first forming mechanism to rotate reciprocally to avoid defects on the surface of the steel wire. The first forming mechanism and the second forming mechanism are installed inside a fixed box. A frame is provided at the bottom of the fixed box. The guiding assembly is arranged at the feeding end of the fixed box, and the winding assembly is arranged at the discharging end of the fixed box. The adjusting mechanism is installed outside the first forming mechanism, and a switching mechanism for detecting an increase in the resistance of the second forming mechanism is installed between the second forming mechanism and the first forming mechanism.

[0004] Currently, during the process of drawing steel wire, a large amount of heat is generated due to friction and deformation of the steel wire. High temperature will accelerate the chemical reaction between the surface of the steel wire and oxygen, resulting in oxidation and rusting of the steel wire surface. Rust will damage the flatness of the steel wire surface, seriously affecting the appearance quality of the steel wire. At the same time, oxidation and rusting will damage the microstructure of the steel wire, reducing its mechanical properties such as strength, toughness, and ductility. Products made of such steel wire with degraded mechanical properties are prone to safety hazards during use. Summary of the Invention

[0005] In view of the above-mentioned drawbacks of the prior art, the present invention provides a wire drawing machine cooling device with rust prevention and scale removal functions, which can effectively solve the problems in the above background art.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: The present invention provides a wire drawing machine cooling device with rust prevention and scale removal functions, including: The machine body, a fixing plate is fixedly connected to the front side of the machine body, a first drawing drum and a second drawing drum are respectively rotatably connected to the front side of the fixing plate, a wire drawing die and an emulsion pipe are respectively fixedly connected to the front side of the fixing plate, three emulsion pipes are provided and are equidistantly distributed on the front side of the fixing plate, and a liquid collecting plate is fixedly connected to the front side of the fixing plate; A cleaning box, the bottom of the cleaning box is fixedly connected to the upper surface of the liquid collecting plate, a sliding shaft is fixedly connected to the inner wall of the cleaning box, a first sliding ring, a second sliding ring and a third sliding ring are respectively slidably connected to the outer circumferential surface of the sliding shaft, the second sliding ring is located between the first sliding ring and the third sliding ring, an extrusion block is fixedly connected to the inner wall of the first sliding ring, a first conical ring is fixedly connected to the inner wall of the second sliding ring, and a second conical ring is fixedly connected to the inner wall of the third sliding ring.

[0007] Furthermore, eight extrusion blocks are provided and are circumferentially arranged in an array on the inner wall of the first sliding ring, both ends of each extrusion block are inclined, and the inner diameter of the first conical ring is larger than the inner diameter of the second conical ring.

[0008] Furthermore, a connecting cylinder is fixedly connected to the outer circumferential surface of the sliding shaft, four groups of connecting cylinders are provided, a connecting ring is fixedly connected between the connecting cylinders in the same group, a resisting strip is fixedly connected to the inner wall of the connecting ring, a plurality of resisting strips are provided and are circumferentially arranged in an array on the inner wall of the connecting ring, and both ends of each resisting strip are arc-shaped.

[0009] Furthermore, three push-pull rods are arranged inside the cleaning box, the three push-pull rods are respectively fixedly connected to the tops of the first sliding ring, the second sliding ring and the third sliding ring, push-pull blocks are respectively rotatably connected to both ends of the push-pull rods, and lifting rods are respectively rotatably connected to the ends of the push-pull blocks away from the push-pull rods.

[0010] Furthermore, a support rod is fixedly connected to the outer circumferential surface of the connecting ring, a lifting slide rail is fixedly connected to the end of the support rod away from the connecting ring, and one end of the lifting rod is slidably connected inside the lifting slide rail.

[0011] Furthermore, a rotating shaft rod is rotatably connected to the front side of the fixing plate, three rotating shaft rods are provided and are equidistantly distributed on the front side of the fixing plate, shaft blocks are respectively fixedly connected to the ends of the rotating shaft rods away from the fixing plate, a square slide rail is fixedly connected to the outer circumferential surface of the shaft block, and one end of the lifting rod away from the lifting slide rail is slidably connected inside the square slide rail.

[0012] Furthermore, a driving component is fixedly connected to the side of the machine body away from the fixing plate, a first rotating block is fixedly connected to the end of the first drawing drum close to the fixing plate, a second rotating block is fixedly connected to the end of the second drawing drum close to the fixing plate, and the output end of the driving component is fixedly connected to the first rotating block.

[0014] The technical solution provided by the present invention has the following beneficial effects compared with the prior art: By providing a first slip ring, a second slip ring and a third slip ring, the reciprocating motion of the first slip ring drives the reciprocating motion of a plurality of extrusion blocks. Under the extrusion action of the plurality of extrusion blocks, the plurality of extrusion blocks extrude the rust layer on the surface of the steel wire to generate multiple "indentations", thereby increasing the surface area of the rust layer on the surface of the steel wire and accelerating the "cleaning efficiency" of the rust remover on the rust layer on the surface of the steel wire. The reciprocating motion of the second slip ring and the third slip ring respectively drives the first tapered ring and the second tapered ring to reciprocate along the axis of the steel wire. Since the inner diameter of the first tapered ring is larger than that of the second tapered ring, the first tapered ring first scrapes the outer layer of the rust layer on the surface of the steel wire, and the second tapered ring then scrapes the inner layer of the rust layer on the surface of the steel wire. There is a bonding stress between the rust layer and the steel wire. Scraping off at one time is likely to induce microcracks, and the layered treatment can gradually release the stress and reduce the internal damage of the steel wire.

[0021] There are eight extrusion blocks 25, which are arranged in a circumferential array on the inner wall of the first sliding ring 22, both ends of each extrusion block 25 are inclined, and the inner diameter of the first conical ring 26 is larger than the inner diameter of the second conical ring 27.

[0022] A connecting cylinder 3 is fixedly connected to the circumferential outer surface of the sliding shaft 21, there are four groups of connecting cylinders 3, a connecting ring 31 is fixedly connected between the connecting cylinders 3 in the same group, a resisting bar 32 is fixedly connected to the inner wall of the connecting ring 31, there are multiple resisting bars 32, which are arranged in a circumferential array on the inner wall of the connecting ring 31, and both ends of each resisting bar 32 are arc-shaped.

[0023] Three push-pull rods 4 are arranged inside the cleaning box 2, the three push-pull rods 4 are respectively fixedly connected to the tops of the first sliding ring 22, the second sliding ring 23, and the third sliding ring 24, a push-pull block 41 is rotatably connected to both ends of the push-pull rod 4, and a lifting rod 42 is rotatably connected to the end of the push-pull block 41 away from the push-pull rod 4.

[0024] A support rod 421 is fixedly connected to the circumferential outer surface of the connecting ring 31, a lifting slide rail 422 is fixedly connected to the end of the support rod 421 away from the connecting ring 31, and one end of the lifting rod 42 is slidably connected inside the lifting slide rail 422.

[0025] A rotating shaft rod 43 is rotatably connected to the front side of the fixing plate 16, there are three rotating shaft rods 43, which are equidistantly distributed on the front side of the fixing plate 16, a shaft block 44 is fixedly connected to the end of the rotating shaft rod 43 away from the fixing plate 16, a square slide rail 45 is fixedly connected to the circumferential outer surface of the shaft block 44, and one end of the lifting rod 42 away from the lifting slide rail 422 is slidably connected inside the square slide rail 45.

[0026] A driving assembly 5 is fixedly connected to the side of the machine body 1 away from the fixing plate 16, a first rotating block 51 is fixedly connected to the end of the first drawing drum 11 close to the fixing plate 16, a second rotating block 52 is fixedly connected to the end of the second drawing drum 12 close to the fixing plate 16, and the output end of the driving assembly 5 is fixedly connected to the first rotating block 51.

[0027] One end of the first rotating block 51 away from the first drawing drum 11 is fixedly connected with a first gear 531. One end of the second rotating block 52 away from the second drawing drum 12 is fixedly connected with a second gear 532. One end of the rotating shaft rod 43 away from the shaft block 44 is fixedly connected with a third gear 533. A transmission belt 534 is commonly sleeved between the first gear 531, the second gear 532 and the third gear 533.

[0028] Working principle: Wire pay-off process: In practical applications, as Figure 3 shown, the steel wire is led out through the wire pay-off device and passes through the inner hole of the wire drawing die 13 along the wire groove of the second drawing drum 12, then wound around the wire groove of the first drawing drum 11, and then wound around the wire groove of the second drawing drum 12 along the wire groove of the first drawing drum 11, then passes through another inner hole of the wire drawing die 13 along the wire groove of the second drawing drum 12, and is wound around the wire groove of the first drawing drum 11 again. By winding the steel wire back and forth on the wire grooves of the second drawing drum 12 and the first drawing drum 11 for multiple times, the drawing force is generated by the friction between the first drawing drum 11 and the second drawing drum 12 and the steel wire, and the inner hole diameter of the wire drawing die 13 through which the steel wire passes gradually decreases, thus forming a "diameter reduction" channel.

[0029] Wire drawing process: By starting the driving assembly 5, the driving assembly 5 drives the first rotating block 51 to rotate through the output end. The rotating first rotating block 51 drives the first gear 531 on its circumferential outer surface to rotate synchronously. The rotating first gear 531 drives the second gear 532 to rotate synchronously through the transmission belt 534. The rotating second gear 532 drives the second rotating block 52 to rotate synchronously. The rotating first rotating block 51 and the rotating second rotating block 52 drive the first drawing drum 11 and the second drawing drum 12 to rotate synchronously in front of the fixed plate 16 respectively. Since the steel wire is wound around the wire grooves of the first drawing drum 11 and the second drawing drum 12, the rotation of the first drawing drum 11 and the second drawing drum 12 pulls the steel wire to pass through the inner holes of the wire drawing die 13 in sequence through the friction force. The steel wire is subjected to the extrusion and stretching effects of the inner hole wall of the wire drawing die 13. The diameter of the steel wire gradually decreases, the length of the steel wire gradually increases, and the steel wire undergoes plastic deformation. Finally, the wire take-up device winds the drawn and formed steel wire into a finished product.

[0030] As a further embodiment of the present invention, by opening a liquid outlet at the bottom of the three emulsion tubes 14, the cooling emulsion (a mixed liquid containing lubricating and cooling components) is transported from the storage device to the inside of the three emulsion tubes 14, and the three emulsion tubes 14 spray the emulsion downward through the liquid outlet, so that the emulsion contacts the steel wire located at the first drawing drum 11, the second drawing drum 12 and the drawing die 13. During the drawing, the steel wire generates heat due to friction caused by the stretching deformation, and the temperature of the steel wire rises sharply. At this time, the emulsion transported by the emulsion tube 14 is sprayed , immersion and overflow, etc. to directly cover the surface of the steel wire, so that the high-temperature steel wire and the low-temperature emulsion "contact and exchange heat". The emulsion temperature is lower than the steel wire. When in contact, the heat of the steel wire is "absorbed" by heat conduction (direct contact to transfer heat) and convection heat transfer (emulsion flow takes away heat), so that the steel wire is cooled down. The emulsion that absorbs heat accumulates downward inside the liquid collecting plate 15, and flows back to the cooling system (such as cooling tower, plate heat exchanger) through the pipeline. After being cooled by air cooling, water cooling, etc., it is sent back to the wire drawing area through the emulsion pipe 14 to continuously cool the steel wire.

[0031] As a further implementation scheme of the present invention, during the process of the steel wire passing through the cleaning box 2, a rust remover (such as a weakly acidic or neutral rust remover is used to remove the rust layer by chemical reaction) is placed inside the cleaning box 2. The rust remover reacts chemically with the rust layer on the surface of the steel wire to clean the rust layer on the surface of the steel wire. The steel wire first passes through a plurality of abutment bars 32 on the inner wall of the connecting ring 31. Under the limiting action of the plurality of abutment bars 32, the axis of the steel wire is kept consistent with the axis of the connecting ring 31, thereby straightening the steel wire inside the cleaning box 2 (to prevent the steel wire inside the cleaning box 2 from bending). At this time, the rotating No. 1 gear 531 drives the three No. 3 gears 533 to rotate synchronously through the transmission belt 534. The three No. 3 gears 533 respectively drive the three rotating shafts 43 located on the front side of the fixed plate 16 to rotate synchronously. The rotating rotating shaft 43 drives the shaft block 44 at one end thereof to rotate around its own axis. The rotating shaft block 44 drives the two square slide rails 45 on its circumferential outer surface to rotate around the axis of the shaft block 44. Figure 11As shown, when the square slide rail 45 starts to rotate, under the limiting action of the lifting slide rail 422, the square slide rail 45 pushes the lifting rod 42 inside it to slide downward along the lifting slide rail 422. After the square slide rail 45 rotates 45 degrees, at this time, the lifting rod 42 is located at the "corner" of the square slide rail 45 (at this time, the distance between the lifting rod 42 and the shaft block 44 reaches the maximum). The square slide rail 45 continues to rotate, and the rotating square slide rail 45 pulls the lifting rod 42 inside it to slide upward along the lifting slide rail 422. After the square slide rail 45 rotates 45 degrees again, at this time, the lifting rod 42 is located at the "midpoint" of the square slide rail 45 (at this time, the distance between the lifting rod 42 and the shaft block 44 reaches the minimum). In this way, the rotating square slide rail 45 drives the lifting rod 42 inside it to perform reciprocating up and down motion along the lifting slide rail 422. During the process of the lifting rod 42 moving up and down along the lifting slide rail 422, as Figure 10 shown, the top end of the push-pull block 41 is driven by the lifting rod 42 to perform reciprocating up and down motion along the lifting slide rail 422. Under the connection action of the push-pull block 41, the push-pull block 41 drives the push-pull rod 4 at its bottom end to perform reciprocating motion along the axis of the sliding shaft 21. In this way, the continuous rotation of the three rotating shaft rods 43 drives the three push-pull rods 4 inside the cleaning box 2 to perform reciprocating motion along the axis of the sliding shaft 21.

[0032] As a further implementation scheme of the present invention, as Figure 8 shown, the steel wire inside the cleaning box 2 first passes through the first sliding ring 22, then passes through the second sliding ring 23, and finally passes through the third sliding ring 24. During the process of the steel wire passing through the first sliding ring 22, the reciprocating push-pull rod 4 drives the first sliding ring 22 to perform reciprocating motion along the axis of the sliding shaft 21. The first sliding ring 22 drives a plurality of extrusion blocks 25 on its inner wall to perform reciprocating motion along the axis of the steel wire. Under the action of the inclined angles at both ends of the extrusion blocks 25, a plurality of extrusion blocks 25 initially extrude the rust layer on the surface of the steel wire through the inclined angle at one end. Under the extrusion action of the extrusion blocks 25, "indentations" are generated on the rust layer on the surface of the steel wire, increasing the surface area of the rust layer on the surface of the steel wire, thereby increasing the contact area between the rust layer on the surface of the steel wire and the rust remover, and improving the reaction rate between the rust layer on the surface of the steel wire and the rust remover.

[0033] As a further implementation scheme of the present invention, in the process of the steel wire passing through the No. 2 slip ring 23, the reciprocating push-pull rod 4 drives the No. 2 slip ring 23 to reciprocate along the axis of the sliding shaft 21, and the No. 2 slip ring 23 drives the No. 1 conical ring 26 on its inner wall to reciprocate along the axis of the steel wire. Under the reciprocating impact of the No. 1 conical ring 26, the No. 1 conical ring 26 performs preliminary rust removal and cleaning on the steel wire passing through the interior thereof. In the process of the steel wire passing through the No. 3 slip ring 24, the reciprocating push-pull rod 4 drives the No. 3 slip ring 24 to reciprocate along the axis of the sliding shaft 21, and the No. 3 slip ring 24 drives the No. 2 conical ring 27 on its inner wall to reciprocate along the axis of the steel wire. Under the reciprocating impact of the No. 2 conical ring 27, the No. 2 conical ring 27 performs deep rust removal and cleaning on the steel wire passing through the interior thereof.

[0034] By setting a No. 1 slip ring 22, a No. 2 slip ring 23 and a No. 3 slip ring 24, the reciprocating motion of the No. 1 slip ring 22 drives the multiple extrusion blocks 25 to reciprocate. Under the extrusion action of the multiple extrusion blocks 25, the multiple extrusion blocks 25 squeeze the rust layer on the surface of the steel wire to produce multiple "indentations", thereby increasing the surface area of the rust layer on the surface of the steel wire and accelerating the "cleaning efficiency" of the rust remover on the rust layer on the surface of the steel wire. The reciprocating motion of the No. 2 slip ring 23 and the No. 3 slip ring 24 respectively drives the No. 1 conical ring 26 and the No. 2 conical ring 27 to reciprocate along the axis of the steel wire. Since the inner diameter of the No. 1 conical ring 26 is larger than the inner diameter of the No. 2 conical ring 27, the No. 1 conical ring 26 first scrapes off the outer layer of the rust layer on the surface of the steel wire, and the No. 2 conical ring 27 scrapes off the inner layer of the rust layer on the surface of the steel wire. There is a bonding stress between the rust layer and the steel wire. One-time scraping is likely to induce micro cracks. Layered treatment can gradually release stress and reduce internal damage to the steel wire.

[0035] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
