Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire drawing equipment technology, and in particular to a diamond busbar cold drawing machine. Background Technology
[0002] Diamond busbars are produced using high-quality raw materials (tungsten wire), advanced heat treatment processes, and wire drawing processes. They are characterized by high strength, high precision dimensions, and excellent surface cleanliness. The wire drawing process mainly involves hot drawing using a wire drawing machine. The wire drawing machine mainly unwinds the wire from the roll and winds one end onto a take-up reel. During the unwinding and take-up process, the wire passes through the wire drawing module, which causes the wire to become thinner, thus achieving the required diameter.
[0003] However, in the existing technology, diamond busbars are generally heated by a heating mechanism during the drawing process to achieve hot drawing of the diamond busbars, as shown in Chinese patent CN117732898A. Since the diamond busbars need to be heated before drawing, high-speed drawing of the diamond busbars cannot be achieved, resulting in low drawing efficiency. Therefore, the existing wire drawing machines need to be improved. Utility Model Content
[0004] The purpose of this invention is to provide a cold drawing machine for diamond busbars that has high drawing efficiency and can ensure drawing quality.
[0005] To solve the above technical problems, the present invention can be implemented using the following technical solutions:
[0006] A cold drawing machine for diamond busbars includes a cabinet, a wire feeding mechanism, a wire drawing mechanism, and a wire taking-up mechanism. The wire feeding mechanism, wire drawing mechanism, and wire taking-up mechanism are sequentially arranged on the cabinet along the wire drawing direction of the diamond busbar. A storage tank for storing coolant is also provided inside the cabinet. The wire drawing mechanism includes a wire drawing box, wire drawing rollers, and a wire drawing die frame. The wire drawing rollers and the wire drawing die frame are respectively installed in the wire drawing box. There are two sets of wire drawing rollers.

[0009] In one embodiment, the bottom of the wire drawing die frame is provided with a return flow hole, and the return flow hole is connected to the bottom of the mounting groove.
[0010] In one embodiment, the wire drawing die frame has a mounting plate with adjustment holes. The mounting plate is fixed to the wire drawing box through the adjustment holes, and the vertical position of the mounting plate can be adjusted through the adjustment holes.
[0011] In one embodiment, an angle adjustment mechanism is provided between the wire drawing mechanism and the wire taking mechanism, and the angle adjustment mechanism is installed on the side wall of the wire drawing box.

[0016] This utility model relates to a diamond busbar cold drawing machine. A wire feeding mechanism conveys the diamond busbar to a wire drawing mechanism for drawing to a set diameter. While the diamond busbar is being drawn by the wire drawing die on the wire drawing die frame in the wire drawing mechanism, coolant in the storage tank is sprayed directly onto the wire drawing die. This allows for simultaneous drawing and spraying of the diamond busbar, thereby achieving cold drawing of the diamond busbar. The drawn diamond busbar is then wound up by a wire take-up mechanism. By simultaneously drawing and spraying the diamond busbar, the drawing efficiency of the diamond busbar can be improved and the drawing quality can be ensured. Attached Figure Description

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0032] Please see Figures 1 to 3 A cold drawing machine for diamond busbars includes a cabinet 100, a wire feeding mechanism 200, a wire drawing mechanism 300, and a wire taking-up mechanism 400. The wire feeding mechanism 200, the wire drawing mechanism 300, and the wire taking-up mechanism 400 are sequentially arranged on the cabinet 100 along the wire drawing direction of the diamond busbar. A storage tank for storing coolant is also provided inside the cabinet 100 (not shown in the figure). The wire drawing mechanism 300 includes a wire drawing box 310, a wire drawing roller 320, and a wire drawing die frame 330. The wire drawing roller 320 and the wire drawing die frame 330 are respectively installed in the wire drawing box 310, and there are two sets of wire drawing rollers 320. The wire drawing die frame 330 is located between the two sets of wire drawing rollers 320 and is connected to the storage tank. Several wire drawing dies 340 are provided on the wire drawing die frame 330. The coolant in the storage tank can be sprayed onto the wire drawing dies 340.
[0033] In this embodiment, the diamond busbar coil to be drawn is installed at the wire feeding mechanism 200, which then conveys the diamond busbar to the drawing mechanism 300. The drawing mechanism 300 draws the diamond busbar to a set diameter. Specifically, during drawing, the diamond busbar passes through the side wall of the drawing box 310 into the first set of drawing rollers 320, then is conveyed from the first set of drawing rollers 320 to the drawing die frame 330, and finally passes through the drawing die 340 on the drawing die frame 330 to the second set of drawing rollers 320. The diamond busbar is then drawn through the drawing die 340 (from thick to thin). In order to achieve the set diameter, the diamond busbar will move around the first set of drawing rollers. The drawing die 340 on the drawing die 320 and the second set of drawing rollers 320 draw a set number of turns to achieve multi-pass drawing of the diamond wire, drawing the diamond wire to the required diameter. After drawing, the diamond wire passes through the side wall of the drawing box 310 to the take-up mechanism 400, where it is taken up into a coil. In this embodiment, when the diamond wire is drawn by the drawing die 340, the coolant in the storage tank is sprayed onto the drawing die 340, so that the diamond wire is drawn and sprayed at the same time, thereby achieving cold drawing of the diamond wire. By drawing and spraying the diamond wire at the same time, the drawing efficiency of the diamond wire can be improved and the drawing quality can be ensured.
[0034] Please see Figure 3 Since the diamond busbar requires multiple back-and-forth drawing processes during the drawing process, multiple corresponding drawing dies 340 need to be set on the drawing die frame 330. Therefore, in this embodiment, the drawing die frame 330 has two sets of drawing grooves 331 arranged side by side, and several mounting grooves 332 are provided in the drawing grooves 331. The mounting grooves 332 in the two sets of drawing grooves 331 are staggered, and the drawing dies 340 are set in the mounting grooves 332. By staggering the mounting grooves 332 in the two sets of drawing grooves 331, the drawing dies 340 set in the mounting grooves 332 can also be staggered, so that the drawing dies 340 in the two rows of drawing grooves 331 will not obstruct each other, thereby realizing multiple back-and-forth drawing of the diamond busbar to draw the diamond busbar to the required diameter.
[0035] Please see Figure 4 and Figure 5 In order to spray coolant onto the drawing die 340 in the two rows of drawing grooves 331, in this embodiment, a liquid delivery channel 333 is provided inside the drawing die frame 330, and two sets of liquid channels 333 are provided, which correspond to the two sets of drawing grooves 331 respectively. The liquid delivery channel 333 can be connected to the liquid storage tank through a pipe. At the same time, a spray hole 334 communicating with the liquid delivery channel 333 is opened on the side wall of the mounting groove 332.
[0036] When the diamond busbar is drawn through the drawing die 340, a pump can be used to deliver coolant from the storage tank to the drawing die frame 330. The coolant then flows along the drawing die 333 and is sprayed outward from the spray hole 334 on the side wall of the mounting groove 332. Since the drawing die 340 is located in the mounting groove 332, the coolant will be sprayed onto the drawing die 340, thereby spraying the diamond busbar to achieve cold drawing of the diamond busbar.
[0037] Furthermore, since the coolant, after being sprayed onto the drawing die 340, falls into the mounting groove 332, a return flow hole 335 is provided at the bottom of the drawing die frame 330 in this embodiment to recycle the coolant in the mounting groove 332. The return flow hole 335 is connected to the bottom of the mounting groove 332. The coolant sprayed into the mounting groove 332 can flow back into the drawing box 310 through the return flow hole 335. The bottom of the drawing box 310 is connected to a storage tank via a pipe. After the coolant flows back into the drawing box 310, it will flow back into the storage tank through the pipe at the bottom of the drawing box 310, thus achieving the recycling of the coolant.
[0038] Please see Figure 3 and Figure 5 To improve the straightness of the diamond wire drawing process, the wire drawing die holder 330 in this embodiment has a mounting plate 336 with an adjustment hole 337. The mounting plate 336 is fixed to the wire drawing box 310 through the adjustment hole 337, and its vertical position can be adjusted. The height of the wire drawing die holder 330 can be adjusted through the adjustment hole 337, ensuring that the height of the wire drawing die 340 on the wire drawing die holder 330 matches the height of the two sets of wire drawing rollers 320. This adjusts the straightness of the conveying between the wire drawing die 340 and the two sets of wire drawing rollers 320, preventing damage to the diamond wire drawing process and ensuring uniform stress on the diamond wire drawing, thus guaranteeing the quality of the diamond wire drawing.
[0039] Please see Figure 2 and Figure 6 Similarly, in order to ensure the straightness of the diamond wire during the cold drawing process, an angle adjustment mechanism 500 is also provided between the wire drawing mechanism 300 and the wire taking-up mechanism 400. The angle adjustment mechanism 500 is installed on the side wall of the wire drawing box 310. The center position of the diamond wire output by the wire drawing mechanism can be adjusted through the angle adjustment mechanism 500, thereby ensuring the straightness of the diamond wire during drawing and improving the quality of the drawing process.
[0040] Specifically, the angle adjustment mechanism 500 includes a universal bearing housing 510, a hollow shaft 520, and a top sleeve 530. The universal bearing housing 510 is installed on the side wall of the wire drawing box 310. The hollow shaft 520 is disposed inside the universal bearing housing 510, and a spherical self-aligning ring 540 is sleeved on the hollow shaft 520. The outer wall of the spherical self-aligning ring 540 is in spherical rotational engagement with the inner wall of the universal bearing housing 510. Radial adjusting screws 550 that abut against the hollow shaft 520 are distributed circumferentially on the outer wall of the universal bearing housing 510. After the diamond wire is drawn by the wire drawing mechanism 300, it passes through the top sleeves 530 at both ends of the hollow shaft 520 to the wire take-up mechanism 400. By turning the adjusting screws 550 at different positions, the adjusting screws 550 act on the corresponding outer wall of the hollow shaft 520, thereby causing the spherical self-aligning ring 540 on the hollow shaft 520 to rotate along the inner spherical surface of the universal bearing seat 510, thus adjusting the angle of the hollow shaft 520. When the angle of the hollow shaft 520 is adjusted, the angle of the top sleeve 530 is also adjusted, thereby adjusting the center position of the diamond wire and setting the straightness of the conveying, thus ensuring the drawing quality of the diamond wire. The angle adjustment mechanism 500 is prior art, so it will not be described in detail here. For details, please refer to Chinese Patent: CN203494916U.
[0041] In addition, after the diamond busbar passes through the wire drawing box 310, the angle adjustment mechanism 500 scrapes off excess coolant from the surface of the diamond busbar. To recycle the scraped coolant, a drip tray 311 is provided below the angle adjustment mechanism 500. The drip tray 311 is installed at an angle on the outer wall of the wire drawing box 310, and a liquid collection hole 312 that cooperates with the drip tray 311 is opened on the side wall of the wire drawing box 310. The scraped coolant is collected by the drip tray 311, and the collected coolant flows along the inclined drip tray 311 and flows into the wire drawing box 310 through the liquid collection hole 312. Finally, it flows into the storage tank through a pipe, so as to realize the recycling of coolant and prevent coolant from dripping onto the cabinet 100, keeping the cabinet 100 clean and tidy.
[0042] Finally, please see Figure 1 To ensure smooth wire drawing, the wire feeding mechanism 200 in this embodiment includes a wire feeding wheel 210, a wire feeding tension adjusting wheel 220, a swing wheel 230, and a wire feeding guide wheel 240, arranged sequentially along the wire drawing direction of the diamond wire. The wire taking-up mechanism 400 includes a wire taking-up guide wheel 410, a wire taking-up tension adjusting wheel 420, and a wire taking-up wheel 430, arranged sequentially along the wire drawing direction of the diamond wire.
[0043] The wire feeding wheel 210 is used to install the diamond busbar coil to be drawn. The diamond busbar then passes sequentially through the wire feeding tension adjusting wheel 220, the swing wheel 230, and the wire feeding guide wheel 240 to the wire drawing mechanism 300 for drawing. The wire feeding tension adjusting wheel 220 can adjust the wire feeding tension of the diamond busbar, thereby avoiding the diamond busbar from being too tight or too loose during the conveying process. The swing wheel 230 can adjust the angle of the diamond busbar conveying, making the diamond busbar easier to convey. The wire feeding guide wheel 240 facilitates the transport of the diamond wire to the wire drawing mechanism 300; the wire take-up guide wheel 410 facilitates the guidance of the drawn diamond wire; the wire take-up tension adjustment wheel 420 can adjust the tension of the diamond wire during take-up; and the wire take-up wheel 430 can take up the drawn diamond wire, ultimately enabling the diamond wire to be drawn smoothly and stably. The wire feeding mechanism 200 and the wire take-up mechanism 400 are existing technologies, so they will not be described in detail here.
[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description; however, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model; furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
