Description

Technical Field

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

[0002] Wire drawing machines are metal wire processing equipment that synchronizes the linear speed of the steel wire and the drum during the drawing process, without relative slippage. They are mainly divided into two categories: wire-accumulating type and non-wire-accumulating type. Wire-accumulating type includes pulley type and double-drum wire drawing machines. The former has a simple structure and low cost, and is suitable for non-ferrous metals and low-carbon steel wires, but it has problems such as complex wire routing and limited speed. The latter improves the amount of wire accumulated and cooling efficiency through the double-drum structure, and reduces wire twisting.

[0003] Friction powder is frequently used in wire drawing machines. The main function of friction powder (usually referring to wire drawing powder) is lubrication. By reducing friction between the metal and the die, it lowers drawing resistance, protects the metal surface quality, and extends die life. The specific functions of friction powder are mainly as follows: 1. Reduce the coefficient of friction: The friction powder forms a lubricating film on the metal surface, which effectively reduces the frictional resistance during the drawing process and avoids wear caused by direct contact between the metal and the die; 2. Protect metal surfaces: The lubricating film can prevent metal from sintering or oxidizing under high temperature and high pressure, maintain surface smoothness, and improve product appearance and corrosion resistance; 3. Extends mold life: The layered structure of the lubricating film can stretch and deform with the metal, reducing mold wear and lowering the replacement frequency; 4. Energy saving and environmental protection: The new environmentally friendly fiber-drawing powder formula (such as containing sulfonated castor oil, tall oil and other ingredients) has the characteristics of high temperature and high pressure resistance, non-toxic and non-polluting, which meets environmental protection requirements.

[0004] Chinese Patent Publication No. CN202824192U discloses a waste scrap wire drawing machine, including a mold box, a motor, a gearbox, rollers, and a take-up drum. The motor is connected to the gearbox via a transmission belt, and the output shaft of the gearbox is connected to the rollers and the take-up drum. The gearbox, motor, and rollers form a wire drawing assembly. A mold box containing friction powder is provided in front of each roller. At least two wire drawing assemblies are arranged in a straight line to form a wire drawing unit. The end of the wire drawing unit is connected to the take-up drum via the mold box. Compared with traditional waste scrap wire drawing machines, this invention has a simpler structure and higher efficiency, making it suitable for the development needs of equipment miniaturization.

[0005] The wire in the above-mentioned patent passes through a mold box before being wound around the roller. After passing through the mold box, the wire is covered with a layer of friction powder to make the roller 4 pull the wire more reliably and the surface of the wire smoother.

[0006] However, the above-mentioned patent still has the following problems: when the friction powder located above the wire in the mold box is consumed, the local surface of the wire cannot be covered with friction powder during the process of the wire passing through the mold box, which will affect the subsequent drawing process.

[0019] 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.

[0020] Please see Figure 1-3 This utility model provides a technical solution: A waste scrap wire drawing machine includes at least two sets of wire drawing components 1 (three sets of wire drawing components 1 are provided in this embodiment) arranged sequentially on the same production line, and a winding machine 2 located at the end of the production line. Each wire drawing component 1 includes a frame 101 and a powder applicator 102 and a roller 103, both mounted on the frame 101. During wire drawing, one end of the wire 3 first passes through the powder applicator 102, then winds around the roller 103, and then sequentially passes through the powder applicator 102 and roller 103 of the next set of wire drawing components 1, and finally winds around the winding machine 2. The function of the powder applicator 102 is to ensure that the outer surface of the wire 3 passing through it is always coated with a layer of friction powder, so that the roller 103 can pull the wire 3 more reliably and the surface of the wire 3 is smoother. Each roller 103 and winding machine 2 is connected to a motor (not shown in the figure) to facilitate its own rotation.

[0021] Specifically, in this embodiment, the powder applicator 102 includes a barrel 1021 mounted on a frame 101 and a powder pressing mechanism mounted inside the barrel 1021. Two through holes (not shown in the figure) are symmetrically opened on the outer circumference of the barrel 1021 for the wire 3 to pass through. The wire 3 passes through one of the through holes and the powder pressing mechanism in sequence and then exits from the other through hole.

[0022] Specifically, refer to Figure 2 and Figure 3In this embodiment, the powder pressing mechanism includes an upper sleeve 1022 and a lower sleeve 1023 that are slidably connected. Their central axes are collinear. Both the upper sleeve 1022 and the lower sleeve 1023 have a top end and a bottom end. The bottom end of the upper sleeve 1022 extends into the top end of the lower sleeve 1023 and is slidably connected to it. Both the top end of the upper sleeve 1022 and the bottom end of the lower sleeve 1023 are closed. After the upper sleeve 1022 and the lower sleeve 1023 are connected together, friction powder can be injected into the cavity formed by the upper sleeve 1022 and the lower sleeve 1023. The top end of the upper sleeve 1022 is connected to the inner top of the barrel 1021 via an upper spring 1024, and the bottom end of the lower sleeve 1023 is connected to the inner bottom of the barrel 1021 via a lower spring 1025. The central axes of the upper spring 1024, the upper sleeve 1022, the lower sleeve 1023, and the lower spring 1025 are all collinear. To facilitate the smooth passage of the wire 3 through the upper sleeve 1022 and the lower sleeve 1023 after entering the barrel 1021, two symmetrical sliding grooves are provided on both the upper sleeve 1022 and the lower sleeve 1023 in this embodiment. The extension direction of any sliding groove is parallel to the central axis of either the upper sleeve 1022 or the lower sleeve 1023. The width of all four sliding grooves is the same, and the four sliding grooves are interconnected. The four grooves ensure that when the upper spring 1024 and the lower spring 1025 bring the upper sleeve 1022 and the lower sleeve 1023 closer together, the wire 3 will not interfere with the close proximity of the upper sleeve 1022 and the lower sleeve 1023.

[0023] In order to achieve a sliding connection between the upper sleeve 1022 and the lower sleeve 1023, and to prevent the upper sleeve 1022 from rotating during movement so as to avoid misalignment of the two interconnected sliding grooves, a first limiting strip 4 is specially installed on the outer side wall of the upper sleeve 1022 in this embodiment. The inner side wall of the lower sleeve 1023 is provided with a first limiting groove (not marked in the figure) that matches the first limiting strip 4. The length direction of the first limiting strip 4 and the extension direction of the first limiting groove are both parallel to the central axis of the upper sleeve 1022. The first limiting strip 4 and the first limiting groove are slidably connected.

[0024] To prevent the lower sleeve 1023 from rotating during its up-and-down movement within the barrel 1021, thus causing misalignment of the two interconnected sliding grooves, a second limiting strip 5 is installed on the outer side wall of the lower sleeve 1023 in this embodiment. A second limiting groove (not shown in the figure) adapted to the second limiting strip 5 is provided on the inner side wall of the barrel 1021. The length direction of the second limiting strip 5 and the extension direction of the second limiting groove are both parallel to the central axis of the lower sleeve 1023; the second limiting strip 5 is slidably connected to the second limiting groove.

[0025] like Figure 2 or Figure 3As shown, when the upper sleeve 1022 and the lower sleeve 1023 are connected, the chamber formed by the upper sleeve 1022 and the lower sleeve 1023 is filled with friction powder. During the operation of the wire drawing machine, the wire 3 will continuously pass through the friction powder area. In order to reduce the amount of friction powder leaking out from the four grooves, in this embodiment, several elastic rods 6 are installed in a linear array in any groove, and the arrangement direction of the elastic rods 6 is parallel to the central axis of the upper sleeve 1022 or the lower sleeve 1023. In this way, the elastic rods 6 will not hinder the downward movement of the upper sleeve 1022 or the upward movement of the lower sleeve 1023; on the other hand, they can also reduce the amount of friction powder leaking out from the four grooves.

[0026] After the upper sleeve 1022 and the lower sleeve 1023 are connected together, in order to facilitate the injection of friction powder into the cavity formed by the upper sleeve 1022 and the lower sleeve 1023, in this embodiment, a feed pipe 7 that communicates with its own interior is installed at the end of the upper sleeve 1022 away from the lower sleeve 1023.

[0027] Working principle: After the upper sleeve 1022 and the lower sleeve 1023 are connected together, friction powder can be injected into the cavity formed by the upper sleeve 1022 and the lower sleeve 1023 through the feed pipe 7. Figure 2 or Figure 3 From the perspective of the wire drawing machine, as the wire 3 continuously passes through the friction powder area during operation, the wire 3 continuously carries away the friction powder, and the amount of friction powder in the cavity formed by the upper sleeve 1022 and the lower sleeve 1023 gradually decreases. As the amount of friction powder gradually decreases, the lower sleeve 1023 gradually moves upward under the action of the lower spring 1025, and the upper sleeve 1022 gradually moves downward under the action of the upper spring 1024. This ensures that the friction powder always wraps around the wire 3 located in the upper sleeve 1022, so that the part of the wire 3 located in the upper sleeve 1022 is always covered with a layer of friction powder.

[0028] 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. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
