Description

Technical Field

[0001] This utility model relates to the field of wire drawing machine technology, and more specifically, to a wire drawing machine. Background Technology

[0002] According to their uses, wire drawing machines can be divided into metal wire drawing machines (used for pre-processing of metal products such as standard parts), plastic wire drawing machines (specialized complete sets of equipment used in the plastic products industry to produce various hollow and solid round or flat wires from raw materials such as polyester, nylon, polyethylene, polypropylene, and polyester chips for deep processing), and bamboo and wood wire drawing machines (specialized equipment used in the bamboo and wood products industry to make chopsticks, toothpicks, barbecue sticks, etc., and draw out bamboo and wood fibers for further processing).

[0003] Metal wire drawing machines are pre-processing equipment used in the production of standard parts and other metal products. Their purpose is to draw wire or bar stock transported from steel manufacturers to these manufacturers, ensuring that the wire or bar stock meets the raw material processing requirements for standard parts and other metal product manufacturing in terms of diameter, roundness, internal metallographic structure, surface finish, and straightness. Therefore, the quality of the wire or bar stock pre-processing by the wire drawing machine directly affects the product quality of standard parts and other metal product manufacturers. Wire drawing machines belong to the metal products equipment industry and are widely used in the production and pre-processing of metal wire, rope wire, prestressed steel wire, standard parts, and other metal products.

[0004] The wire drawing rollers of a wire drawing machine play a core role in metal processing. Their main functions include: feeding and traction: Through surface texture or groove design, the wire drawing rollers use friction to smoothly pull the steel wire from the unloading device to the processing stage, ensuring continuous and stable feeding; diameter reduction and forming: During the drawing process, the wire drawing rollers and dies work together to gradually reduce the diameter of the steel wire through stable tension, while optimizing surface finish and shape; speed and tension control: The speed is adjusted by an electrical control system, and in conjunction with tension sensors and other devices, the drawing speed and tension of the steel wire are precisely controlled to avoid wire breakage or deformation; adaptability to irregularly shaped wires: Some wire drawing rollers adopt special die designs, which can uniformly apply force to process irregularly shaped wires, improving processing flexibility and efficiency.

[0005] During the wire drawing process, metal debris is generated. This debris is produced because the metal material is subjected to compression, deformation, and friction within the die cavity, causing some metal fragments to detach from the die gaps or surface. These fragments mainly consist of metal surface oxide layers, impurity particles, and tiny metal particles generated by die wear. If these metal fragments are not cleaned promptly, some can easily adhere to the surface of the wire drawing rollers, affecting the normal diameter reduction and surface quality of the wire.

[0006] Chinese Patent Publication No. CN212442594U discloses an automatically lubricated wire drawing machine, comprising a wire drawing machine body with several wire drawing rollers mounted on it. A base is located at the lower part of the wire drawing machine body, and an oil tank is located inside the base. A conveyor belt is positioned at the junction of the wire drawing machine body and the base, and a lubricating block is mounted on the conveyor belt. The height of the lubricating block is equal to the distance between the wire drawing rollers and the conveyor belt, so that when the conveyor belt rotates to the upper part, the lubricating block contacts the bottom of the wire drawing rollers. The oil tank contains lubricating oil, and when the conveyor belt rotates to the lower part, the surface of the lubricating block is immersed in the lubricating oil in the oil tank. This automatically lubricated wire drawing machine can automatically lubricate the wire drawing rollers during operation, improving work efficiency and ensuring the normal operation of the wire drawing machine.

[0007] While the aforementioned wire drawing machine has solved the technical problem of the time-consuming and labor-intensive manual lubrication required by some existing metal wire drawing machines, it still does not solve the problem of how to recover the metal debris generated during the wire drawing process. If metal debris adheres to the lubrication block during the lubrication of the wire drawing roller and is not cleaned in time, this attached metal debris will damage the surface of the wire drawing roller over time; at the same time, some of the metal debris adhering to the surface of the wire drawing roller will also affect the normal reduction of wire diameter and surface quality.

Detailed Implementation

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Example 1 Please see Figure 1 This embodiment provides a technical solution: A wire drawing machine includes a machine body 101. A plurality of wire drawing rollers 201 are arranged horizontally at intervals within the machine body 101. Each wire drawing roller 201 is rotatably connected to the machine body 101. The plurality of wire drawing rollers 201 are installed such that their central axes are parallel to each other, and their lower generatrices in the horizontal direction are all coplanar. A cleaning mechanism and a collecting mechanism are arranged below the plurality of wire drawing rollers 201 within the machine body 101. The cleaning mechanism is used to remove metal debris from the working surfaces (i.e., the outer circumferential surfaces of the wire drawing rollers 201), and the collecting mechanism is used to collect the metal debris from the cleaning mechanism.

[0022] Preferably, in this embodiment, the cleaning mechanism includes a liquid storage tank 301 installed in the wire drawing machine body 101, two first rotating shafts 302 rotatably disposed in the liquid storage tank 301 at intervals, and a conveyor belt 303. Figure 1 The conveyor belt 303 (not shown in the figure) and the wiping strip 304 mounted on the outer surface of the conveyor belt 303, the liquid storage tank 301 for storing lubricating fluid, and the two first rotating shafts 302 connected by the conveyor belt 303. In this embodiment, the conveyor belt 303 and the two first rotating shafts 302 form a belt conveyor mechanism, and one of the first rotating shafts 302 is driven by a drive motor (not shown in the figure), which drives the corresponding first rotating shaft 302 to rotate to ensure the normal operation of this belt conveyor mechanism. The conveyor belt 303 is located below several drawing rollers 201; the wiping strip 304 can sequentially abut against the working surface of each drawing roller 201 during movement; the collection mechanism is located at one end of the conveyor belt 303. In this embodiment, the wiping strip 304 can be made of a sponge with a certain water absorption capacity.

[0023] Specifically, in this embodiment, the conveying direction of the conveyor belt 303 is perpendicular to the central axis of the drawing roller 201; the central axis of any first rotating shaft 302 and the length direction of the wiping strip 304 are parallel to the central axis of the drawing roller 201.

[0024] Preferably, in this embodiment, the number of collection mechanisms is two sets, from Figure 1 From this perspective, the two sets of collection mechanisms are located at the left and right ends of the conveyor belt 303, respectively.

[0025] Specifically, in this embodiment, any collection mechanism includes a second rotating shaft 401 rotatably disposed within the liquid storage tank 301, and a magnetic strip 402 is mounted on the second rotating shaft 401. Figure 1 (not shown in the image), the central axis of the second rotating shaft 401 and the length direction of the magnetic strip 402 are both parallel to the length direction of the wiping strip 304.

[0026] To facilitate the storage of lubricating fluid and reduce the amount of metal debris collected by the collection mechanism falling into the lubricating fluid, two partitions 701 are specially installed inside the storage tank 301 in this embodiment. Figure 1 (Not shown in the image), two partitions 701 and a reservoir 301 enclose a lubricating fluid storage chamber; any partition 701 is located between the corresponding first rotating shaft 302 and the corresponding second rotating shaft 401.

[0027] Working principle: When the wire drawing machine is working, all the wire drawing rollers 201 are rotating, which causes the belt conveyor mechanism consisting of the conveyor belt 303 and the two first rotating shafts 302 to start running, and the wiping strips 304 move synchronously. Figure 1 From the perspective of the device, the wiping strip 304 can first be moved to the underside of the conveyor belt 303, allowing it to pass over the lubricant in the reservoir 301. After passing over the lubricant, the wiping strip 304 will have lubricant adhering to it. The conveyor belt 303 with the adhering lubricant then moves to the top and contacts each wire drawing roller 201 in turn. During the contact between the wiping strip 304 and the wire drawing roller 201, the lubricant on the wiping strip 304 serves two purposes: firstly, it lubricates the wire drawing roller 201; secondly, the wiping strip 304 removes / carries away metal debris adhering to the working surface of the wire drawing roller 201. Some of the removed metal debris remains on the wiping strip 304, while some falls onto the conveyor belt 303. Then the wiping strip 304 continues to move. When the wiping strip 304 moves to the magnetic strip 402 on the left or the magnetic strip 402 on the right, the metal debris on the wiping strip 304 and the conveyor belt 303 will be attracted away by the magnetic strip 402 under the magnetic attraction, thereby achieving the purpose of collecting metal debris.

[0028] Example 2 Please see Figures 2-4The difference between this embodiment and Embodiment 1 is that: in this embodiment, the second rotating shaft 401 is provided with a plurality of grooves arranged in a circular array, the extension direction of any groove is parallel to the central axis of the second rotating shaft 401, and a magnetic strip 402 is installed in any groove. At the same time, a driving gear 501 is installed at one end of each of the two first rotating shafts 302, and two driven gears 601 that mesh with the two driving gears 501 are installed at one end of each of the two second rotating shafts 401.

[0029] Preferably, the lengths of the magnetic strip 402 and the wiping strip 304 are both greater than or equal to the length of the wire drawing roller 201.

[0030] In Embodiment 1, only one magnetic strip 402 is installed on each of the two second rotating shafts 401. After prolonged operation, if a large amount of metal debris adheres to the magnetic strips 402, it will affect their magnetic attraction, thus impacting the collection efficiency of the collection mechanism. The purpose of designing the collection mechanism in this embodiment is to solve the aforementioned problems in Embodiment 1: During operation of the belt conveyor mechanism composed of the conveyor belt 303 and the two first rotating shafts 302, the two second rotating shafts 401 rotate independently under the drive of the gear mechanism. Therefore, several magnetic strips 402 on the second rotating shafts 401 can be aligned with the conveyor belt 303, allowing the same second rotating shaft 401 to attract more metal debris.

[0031] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge.
