Description

Technical Field

[0001] The invention relates to the technical field of steel wire drawing equipment, and in particular to a wire drawing system. Background Art

[0002] Steel wire is the raw material for processing standard parts such as springs, spring washers, and cotter pins. After processing, the steel wire is generally of a fixed wire diameter. When further processed into standard parts, it needs to be drawn again to become thinner and meet the wire diameter requirements of standard parts. In the prior art, wire drawing is generally performed through a wire drawing box. The wire drawing box generally includes a powder box portion containing wire drawing powder, and a wire drawing die connected to the powder box portion. The steel wire passes through the powder box portion and then passes through the wire drawing die so that the wire diameter becomes smaller. In the actual operation process, the steel wire and the wire drawing die react extremely violently during the wire drawing process, which will generate a large amount of heat. It is generally difficult to complete the final wire drawing through one wire drawing. It is necessary to perform continuous operation through multiple sets of wire drawing boxes. After the previous wire drawing box is drawn, a large distance is required to allow the steel wire to cool down before entering the next wire drawing box. This can prevent the steel wire from overheating due to continuous wire drawing, but it also causes the overall equipment to be too long and occupy a large area. Summary of the invention

[0014] Furthermore, the cooling pipeline includes an inlet pipe and an outlet pipe extending from the upper end of the rotating cylinder to the outside thereof, so as to introduce and guide the refrigerant.

[0026] like Figure 1-3As shown, the present embodiment provides a wire drawing system, which includes a mounting table 1, which is in the shape of an elongated strip, and a plurality of wire drawing components are equidistantly arranged on the mounting table 1 from one end to the other end, each wire drawing component includes a wire drawing box 2 and a rotating cylinder 3, and a driver for driving each rotating cylinder 3 to rotate is also arranged under the mounting table 1; cooling water is filled in the rotating cylinder 3, and a cooling pipeline 4 fixed relative to the mounting table 1 is also arranged in the rotating cylinder 3, and both ends of the cooling pipeline 4 extend to the outside of the rotating cylinder 3 and the middle section is located in the cooling water; both ends of the mounting table 1 are fixedly connected with an inlet plate 5 and an outlet plate 6, respectively, and all the wire drawing components are located between the inlet plate 5 and the outlet plate 6, and an inlet plate 5 is provided with The outlet plate 6 is provided with an outlet hole, the steel wire 7 enters the first drawing box 2 through the inlet hole, is then wound on the first rotating drum 3, and then enters the second drawing box 2, and is finally led out of the last drawing box 2 and separated through the outlet hole. A rotating drum 3 is provided between two adjacent drawing boxes 2, and multiple turns of steel wire 7 can be wound around the rotating drum 3, and the cooling water in the rotating drum 3 indirectly cools the steel wire 7 through the wall of the rotating drum 3, so that the steel wire 7 can efficiently achieve the cooling purpose, that is to say, the two adjacent drawing boxes 2 in this scheme can be arranged closer, so that the length of the overall mounting table 1 can be shortened, the overall equipment occupies a smaller area, and the existing The continuous wire drawing operation in the existing technology leads to the problem that the overall equipment occupies a large area; at the same time, a cooling pipeline 4 is also provided in the present scheme, into which a refrigerant can be introduced, and a compressor is used externally to make the refrigerant in a circulating state, similar to the operation mode of a refrigeration air conditioner, so that the cooling water is continuously kept at a low temperature to maintain the cooling effect on the steel wire 7; in a more detailed scheme, an inner cylinder 8 is also fixedly provided in the rotating cylinder 3, and the cooling pipeline 4 is spirally wrapped around the outside of the inner cylinder 8, and a top plate 9 is fixedly connected to the upper end of the inner cylinder 8, and a mounting shaft 10 is fixedly connected to the top plate 9 and the mounting shaft 10 is fixedly extended downward to the outside of the rotating cylinder 3 and connected to the driver, and the cooling pipeline 4 includes a pipe extending from the upper end of the rotating cylinder 3 to the outside of the rotating cylinder 3. The inlet pipe 11 and the outlet pipe 12 outside are used to import and export the refrigerant. The inner cylinder 8 cooperates with the installation shaft 10 to make the rotating cylinder 3 more stably driven by the driver. The driver can be a driving motor. The installation shaft 10 extends to the bottom of the mounting platform 1. The driver is arranged under the mounting platform 1 and connected to the installation shaft 10 (it can be achieved by conventional methods such as gear transmission, belt transmission, etc.), so as to smoothly realize the drive; further, the setting of the inner cylinder 8 also makes the space inside the rotating cylinder 3 become a smaller ring, so that less cooling water is loaded, but the contact efficiency with the cooling pipeline 4 is better, and the cooling water can better exchange heat with the cooling pipeline 4, thereby further ensuring the cooling effect on the steel wire 7.

[0027] like Figure 1-3As shown, in a further scheme, a winding portion 13 is recessed in the outer wall of the middle section of the rotating cylinder 3, and the winding portion 13 is a structure with large ends and a small middle and an arc-shaped transition, so that the steel wire 7 can gather toward the middle during winding, and the cooling water also contacts the corresponding position in the rotating cylinder 3 to achieve cooling of the steel wire 7. During the wire drawing process, the driver also drives the rotating cylinder 3 to be in a synchronous operation state, so that the steel wire 7 can maintain relative static contact with the rotating cylinder 3 during the movement, avoiding friction between the two and inducing new friction heat.

[0028] like Figure 1 , 4 As shown in Figure 5, the wire drawing box 2 includes a powder box portion 14 and a slag box portion 15. A wire drawing die 16 is also arranged in the slag box portion 15. The steel wire 7 passes through the wire drawing die 16 through the powder box portion 14 and then passes through the slag box portion 15. The slag box portion 15 is also connected to a water inlet pipe 17 and a water outlet pipe 18. The powder box portion 14 is similar to that in the prior art and is filled with wire drawing powder. The steel wire 7 adheres to the wire drawing powder after passing through the powder box portion 14, and then enters the wire drawing die 16 for wire drawing. Flowing water can be introduced into the slag box portion 15 through the water inlet pipe 17 and the water outlet pipe 18. In this way, the wire drawing powder, debris, etc. adhered to the steel wire 7 after passing through the wire drawing die 16 and entering the slag box portion 15 will be taken away by the flowing water, and pre-cooling is also performed. In this way, the cooling effect is better in combination with the subsequent cooling at the rotating drum 3. In particular, the wire drawing die 16 is also partially When immersed in flowing water, the wire drawing die 16 can also be cooled, thereby preventing the wire drawing die 16 from overheating; in more detail, the water outlet pipe 18 is connected to the side wall of the slag box part 15, and the water inlet pipe 17 is connected to the bottom of the slag box part 15 and fixedly extends to the bottom of the mounting platform 1 to facilitate the introduction of flowing water. The wire drawing die 16 is provided with a wire drawing hole located above the water outlet pipe 18, so that water can be prevented from entering the wire drawing hole. The slag box part 15 is also provided with an outlet hole 19, and the slag box part 15 is also provided with a roller group that allows the steel wire 7 to be immersed in water, thereby ensuring that the flowing water can smoothly carry away the wire drawing powder and debris. The roller group includes a pair of upper rollers 20 and a pair of lower rollers 21 respectively rotatably connected to the inner wall of the slag box part 15, the two upper rollers 20 are located above the water surface and on both sides of the two lower rollers 21, and the two lower rollers 21 are located below the water surface.

[0029] like Figure 1 , 4As shown, the outlet pipe 18 is also connected to a filter tank 22, and also includes a liquid receiving tank 23 installed on the side of the mounting platform 1, and all the filter tanks 22 are connected to the liquid receiving tank 23. The water in the slag box part 15 first enters the filter tank 22, and then enters the liquid receiving tank 23 after being filtered. The filtered water can be reused, thereby saving water resources; in more detail, the filter tank 22 is also installed on the mounting platform 1, and is close to the side of the mounting platform 1. The side of the filter tank 22 close to the side is located directly above the liquid receiving tank 23, and this side is set as a filter plate 24. The water in the filter tank 22 falls into the liquid receiving tank 23 below after passing through the filter plate 24.

[0030] like Figure 1 , 5 As shown, the powder box portion 14 is also fixedly connected to a mounting arm 25, and the mounting arm 25 is also rotatably connected to a rotating wheel 26. The steel wire 7 enters the powder box portion 14 after passing through the rotating wheel 26. After the steel wire 7 leaves the rotating drum 3, it is guided by the rotating wheel 26 and then enters the powder box portion 14 of the wire pull box, thereby ensuring that the steel wire 7 stably enters the powder box portion 14.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
