[0002] Tungsten wire is a kind of high-performance metal material, which is widely used in various fields. During production, the tungsten wire usually needs to be subjected to wire drawing treatment to improve its strength and toughness, and then subjected to straightening treatment to ensure that its straightness and flatness meet the use requirements. The existing production mode usually separates the wire drawing and straightening processes.

[0025] As Figure 1 shown, the present application provides a wire processing device 100 for wire drawing and straightening.

[0026] In order to clearly illustrate the technical solutions of the present application, the front, back, left, right, up and down are defined as shown in Figure 1

[0027] The wire processing device 100 includes a mounting seat 11, a first drawing wheel 12, a second drawing wheel 13, a drawing die 14, a first straightening wheel 15, a second straightening wheel 16 and a traction wheel 17. The mounting seat 11 serves as a basic frame for supporting the first drawing wheel 12, the second drawing wheel 13, the drawing die 14, the first straightening wheel 15, the second straightening wheel 16 and the traction wheel 17. The first drawing wheel 12 is used to cooperate with the drawing die 14 and the second drawing wheel 13 to draw the wire, the second drawing wheel 13 is used to cooperate with the drawing die 14 and the first drawing wheel 12 to draw the wire, the first straightening wheel 15 is used to cooperate with the second straightening wheel 16 to straighten the wire, and the second straightening wheel 16 is used to cooperate with the first straightening wheel 15 to straighten the wire. The wire is drawn between the first drawing wheel 12, the drawing die 14 and the second drawing wheel 13 by the traction wheel 17, and after the drawing is completed, the wire is conveyed to the first straightening wheel 15 and the second straightening wheel 16 for straightening, so that the wire drawing and straightening processes are realized in the same device, the number of devices required for wire drawing and straightening is reduced, the production efficiency of the wire is improved, and the same processing parameters are kept consistent during the wire drawing and straightening processes, so that the difference in processing parameters does not affect the performance of the wire, thereby improving the production quality of the wire. In the present application, the wire drawn and straightened is tungsten wire.

[0028] It should be noted that the above-mentioned wire can also be of other materials, which is not limited in the present application.

[0029] Specifically, the first drawing wheel 12 is rotationally connected to the mounting seat 11, the second drawing wheel 13 is rotationally connected to the mounting seat 11 and is used to receive the wire on the first drawing wheel 12, and the rotational axis of the second drawing wheel 13 is parallel to the rotational axis of the first drawing wheel 12. The drawing die 14 is fixed to the mounting seat 11, and the drawing die 14 is located between the first drawing wheel 12 and the second drawing wheel 13, so that the wire between the first drawing wheel 12 and the second drawing wheel 13 is drawn. Through the above-mentioned setting, the wire is driven by the first drawing wheel 12 and the second drawing wheel 13, and the wire is transmitted in the same plane between the first drawing wheel 12 and the second drawing wheel 13, so that the wire is uniformly stretched in the straight line direction, thereby improving the wire drawing effect.

[0030] ​Specifically, the first straightening wheel 15 is rotationally connected to the mounting base 11 and used to receive the wire on the second drawing wheel 13; the second straightening wheel 16 has a moving freedom along the direction of the rotation axis of the second drawing wheel 13, and the second straightening wheel 16 cooperates with the first straightening wheel 15 to straighten the wire between the first straightening wheel 15 and the second straightening wheel 16. In the present application, the direction of the rotation axis of the second drawing wheel 13 is the left-right direction in Figure 1 By the above arrangement, the wire after the drawing process is transmitted to the first straightening wheel 15 and the second straightening wheel 16 for straightening, and the second straightening wheel 16 moves in the front-back direction to adjust the position according to the bending direction of the wire, so as to accurately straighten the wire with the bent part, improve the straightening accuracy of the wire, and further improve the quality of the wire production.

[0031] Meanwhile, the wire after the drawing process is transmitted from the second drawing wheel 13 to the first straightening wheel 15 and straightened between the first straightening wheel 15 and the second straightening wheel 16, which can reduce the number of devices required between the drawing process and the straightening process, and can also reduce the steps required between the drawing process and the straightening process, thereby improving the production efficiency of the wire.

[0032] Specifically, the traction wheel 17 is installed on the mounting base 11 and has a rotational freedom, and the traction wheel 17 is located on the side of the second drawing wheel 13 away from the first drawing wheel 12, and the traction wheel 17 is used to wind the wire and provide power for the movement of the wire. By the above arrangement, when the wire is drawn, the traction wheel 17 is used as a power source for the transmission of the wire, and the traction wheel 17 provides stable traction to drive the wire between the first drawing wheel 12 and the second drawing wheel 13 to move at a uniform speed, so as to realize stable drawing of the wire and avoid uneven drawing of the wire due to uneven rotation speed of the first drawing wheel 12 and the second drawing wheel 13, thereby avoiding the situation that the cross-sectional diameter of the wire is not uniform. In addition, the traction wheel 17 can also drive the wire between the first straightening wheel 15 and the second straightening wheel 16 to move at a uniform speed, so as to realize stable straightening of the wire and avoid the problem of incomplete straightening of the wire, thereby avoiding the situation that the wire is still bent after straightening, and further improving the quality of the wire production.

[0033] As shown in Figure 2 The wire processing device 100 includes a first wheel shaft 18 fixed to the mounting base 11, and the first drawing wheel 12 and the first straightening wheel 15 are both rotationally connected to the first wheel shaft 18 and distributed along the axial direction of the first wheel shaft 18. In the present application, the axial direction of the first wheel shaft 18 is the front-back direction in Figure 1The first drawing wheel 12 and the first straightening wheel 15 rotate on the first wheel shaft 18 with the axis of the first wheel shaft 18 as the rotation axis, so that the wire processing device 100 can simultaneously perform the drawing and straightening processes when processing the wire, improve the consistency of the wire in the drawing and straightening processes, thereby improving the production efficiency of the wire and reducing the difference of the same processing parameters in the drawing and straightening processes, and further improving the product quality of the wire production.

[0034] As shown in Figure 3 As an embodiment, the wire processing device 100 includes a second wheel shaft 19 fixed to the mounting seat 11, and a second drawing wheel 13 rotatably connected to the second wheel shaft 19. The axis of the second wheel shaft 19 is parallel to the axis of the first wheel shaft 18. Through the above arrangement, the axis of the second wheel shaft 19 is kept in the same plane as the axis of the first wheel shaft 18, so that the wire is stretched in a straight line during the drawing process and the probability of wire bending is reduced, thereby reducing the workload of subsequent wire straightening and improving the efficiency of wire production.

[0035] As an embodiment, the wire processing device 100 includes a driving mechanism 20 and a third wheel shaft 21 for supporting the second straightening wheel 16, and the second straightening wheel 16 is rotatably connected to the third wheel shaft 21. The driving mechanism 20 is installed on the mounting seat 11, and the third wheel shaft 21 is in transmission connection with the driving mechanism 20. The driving mechanism 20 is used to drive the third wheel shaft 21 to move in the direction of the rotation axis of the third wheel shaft 21, so that the third wheel shaft 21 has a movement degree of freedom along the direction of the rotation axis of the second drawing wheel 13. Through the above arrangement, the second drawing wheel 13 moves along with the third wheel shaft 21 in the direction of the rotation axis of the third wheel shaft 21, so that the second straightening wheel 16 can be adjusted in position according to the bending direction of the wire and the relative position of the first straightening wheel 15, thereby quickly straightening the bending state of the wire and improving the straightening effect of the second straightening wheel 16.

[0036] As an embodiment, the mounting seat 11 includes a mounting portion 111 located between the drawing die 14 and the traction wheel 17, and the second drawing wheel 13 and the driving mechanism 20 are located on the mounting portion 111. The second drawing wheel 13 and the driving mechanism 20 are distributed along the direction of the rotation axis of the second drawing wheel 13. Through the above arrangement, the second drawing wheel 13 and the driving mechanism 20 are arranged separately in the direction of the rotation axis of the second drawing wheel 13, which ensures that the wire part performing the drawing process on the second drawing wheel 13 will not interfere with the wire part performing the straightening process on the second straightening wheel 16, thereby improving the working stability of the second drawing wheel 13 and the driving mechanism 20. At the same time, the wire transmitted on the wire processing device 100 can simultaneously perform the drawing and straightening processes, thereby improving the efficiency of the wire processing device 100 in producing the wire.

[0037] As shown in Figure 4 and Figure 5 The first drawing wheel 12 and the second drawing wheel 13 are provided at least two, and the drawing die 14 includes a drawing hole 141 consistent with the number of the first drawing wheel 12. Through the above-mentioned setting, multiple first drawing wheels 12 and second drawing wheels 13 are provided, and in a single drawing process, the wire is first conveyed from the first first drawing wheel 12 to the first second drawing wheel 13, and then conveyed from the first second drawing wheel 13 to the second first drawing wheel 12. The wire is repeatedly transmitted between the multiple first drawing wheels 12 and the multiple second drawing wheels 13 under the driving of the traction wheel 17, so that the wire is transmitted multiple times between the first drawing wheel 12 and the second drawing wheel 13, and the drawing hole 141 consistent with the number of the first drawing wheel 12 is used to draw the wire multiple times, so as to stably draw the wire to the set size standard, thereby improving the drawing quality of the wire.

[0038] In the present embodiment, the first straightening wheel 15 and the second straightening wheel 16 are provided at least one. The straightening wheel at least performs a straightening process on the wire, so that the wire after drawing is kept linear and straight. Through the above-mentioned setting, the wire is drawn and straightened multiple times, which can improve the yield of the wire after drawing and straightening, thereby improving the production quality of the wire.

[0039] As an embodiment, the wire processing device 100 further comprises a heating assembly 22 mounted on the mounting seat 11. The heating assembly 22 is located between the drawing die 14 and the first drawing wheel 12, so that the heating assembly 22 can heat the wire between the first drawing wheel 12 and the drawing die 14. Through the above-mentioned setting, the wire is preheated before being conveyed into the drawing die 14 for drawing, so that the wire is heated to a preset temperature, wherein the preset temperature refers to the temperature required for the wire to be stretched and deformed, so as to improve the ductility of the wire, facilitate the drawing of the wire by the drawing die 14, and thereby improve the efficiency of the wire in the drawing process.

[0040] Specifically, the drawing die 14 is provided with a heating mechanism 142 for maintaining the temperature of the wire. Through the above-mentioned setting, the heating mechanism 142 can maintain the wire at a preset temperature during drawing in the drawing die 14, thereby improving the ductility of the wire, facilitating the stretching of the wire, avoiding the situation that the wire is difficult to stretch or breaks, and thereby improving the production efficiency and production quality of the wire in the drawing process.

[0041] As an implementation, the wire processing device 100 further comprises a lubricating assembly 113 mounted on the mounting base 11, the lubricating assembly 113 is located between the heating assembly 22 and the first drawing wheel 12, so that the lubricating assembly 113 can lubricate the wire between the first drawing wheel 12 and the heating assembly 22. Through the above arrangement, the wire is added with lubricant in advance before entering the drawing process, so that the wire can be stretched more conveniently during the drawing process and reach the required size, thereby improving the operation efficiency of the drawing process. In this application, the lubricant is graphite milk, which has high heat resistance, so that the lubricating effect of the lubricant on the wire is not reduced when the heating assembly 22 heats the wire, thereby improving the production efficiency of the wire during drawing.

[0042] It should be noted that the material of the lubricant is not limited in this application, as long as it has high heat resistance.

[0043] Specifically, the wire processing device 100 further comprises a take-up wheel (not shown in the figure) for receiving the straightened wire on the traction wheel 17, the take-up wheel is located on the side of the traction wheel 17 away from the second drawing wheel 13.

[0044] For example, the take-up wheel can be mounted on the mounting base 11, which can improve the compactness of the wire processing device 100 and further improve the space utilization of the wire processing device 100, thereby improving the production efficiency of the wire.

[0045] Alternatively, the take-up wheel is separately mounted, which can make the take-up wheel away from the traction wheel 17, the first drawing wheel 12, the second drawing wheel 13, and the first straightening wheel 15 and the second straightening wheel 16 are arranged so that the take-up wheel does not interfere with the wire part being drawn or straightened when recovering the wire drawn and straightened, maintaining the normal operation of the wire processing device 100 and improving the stability of the wire production.

[0046] In this application, the working process of the wire processing device 100 is as follows:

[0047] First, the wire is drawn in the drawing process, one end of the wire to be processed is sequentially threaded through the first drawing wheel 12, the lubricating assembly 113, the heating assembly 22, the drawing die 14, the second drawing wheel 13 and the traction wheel 17, and the wire is drawn in the drawing die 14 under the action of the first drawing wheel 12 and the second drawing wheel 13. According to the above wire conveying mode, the traction wheel 17 drives the wire to repeatedly convey between the first drawing wheel 12 and the second drawing wheel 13 for multiple times of drawing. The wire drawn is sequentially passed through the first straightening wheel 15 and the second straightening wheel 16, and the second straightening wheel 16 is adaptively adjusted on the second drawing wheel 13 rotation axis according to the deflection direction of the wire, and the straightening of the wire is completed.

[0048] It should be understood that all the modifications and variations can be made according to the above description by those skilled in the art, and all these modifications and variations shall belong to the protection scope of the claims attached to the present application.
