The stability of the wire-passing guide wheel 41 is adjusted in cooperation with the counterweight block 37 and the tension sensor 39, which reduces the shaking of the tungsten wire during the wire drawing process and improves the linear parameters of the tungsten wire product. The function of adjusting the guide wheel position through the front guide wheel mechanism 4 and the rear guide wheel mechanism 6 improves the stability of the tungsten wire before and after passing through the mold, thereby improving the product yield.

[0042] Embodiment 2:

[0043] like Figure 1-Figure 10As shown, a wire drawing machine for tungsten wire production, the raw material wire is adaptively speed-regulated by the wire-releasing mechanism 2 to the wire drawing machine frame 1, the raw material wire horizontally passes through the front guide wheel 20, the lubrication pool 19, the heating mechanism 5, the die frame 21 and the rear guide wheel 24 in sequence, then passes through the wire-dividing wheel 33 to enter the traction wheel 32, and finally passes through the tension adjustment mechanism 3 to return to the front guide wheel 20 to complete a cycle; each cycle of the raw material wire completes a die change between each wheel and the die, a total of seven dies, the raw material wire is circulated and drawn into a filament, and is transferred to the wire-receiving mechanism 8 by the traction wheel 32 of the left rear die; the raw material wire passes through the wire-receiving tension adjustment mechanism 47 and the wire-arranging guide wheel 45 in the wire-receiving mechanism 8 to adaptively speed-regulate the filament and rewind it into the wire-receiving assembly 46,

[0044] like Figure 1 As shown in the figure, the wire drawing machine frame 1 is formed by overlapping the profile and the cover plate, and other mechanisms are fixedly installed on the wire drawing machine frame 1 to form a complete structure with good stability. At the same time, the relative positions of the wire release mechanism 2 and the wire take-up mechanism 8 and the wire drawing components can be easily adjusted according to needs;

[0045] like Figure 2 As shown in the figure, the pay-off mechanism 2 includes a bottom plate 10, a first line rail 11, a movable cabinet 12, a raw material line I-wheel 13, a pay-off tension swing rod 14, a wire-passing wheel assembly 15, and a pay-off power mechanism 16; the bottom of the movable cabinet 12 is installed on two sets of first line rails 11, and the wire outlet position of the pay-off mechanism can be adjusted according to the position of the front guide wheel 20; at the same time, the pay-off position can also be adjusted according to the actual drawing die; after the raw material line is paid out from the raw material line I-wheel 13, it passes through the pay-off tension swing rod 14 and the wire-passing wheel assembly 15 and flows into the front guide wheel 20; the pay-off tension swing rod 14 can detect the tension value of the raw material line and feed it back to the pay-off power mechanism 16; the pay-off power mechanism 16 adaptively adjusts the rotation speed according to the feedback value to ensure the pay-off quality;

[0046] The front guide wheel 20, the mold frame 21 and the rear guide wheel 24 form a linear adjustment mechanism, so as to avoid the inconsistency of the horizontal position of the raw material line at three positions caused by the processing error and installation error of the parts; Figure 3 As shown in , there are seven groups of front guide wheels 20, and each group of front guide wheels 20 can be adjusted up, down, left, and right by adjusting screws; Figure 4 As shown, the mold frame 21 can be deflected to a certain angle by adjusting the plate 22; Figure 4 As shown in the figure, the rear guide wheel 24 is composed of six groups and one group of drivers 26. The driver 26 adjusts the rear guide wheel 24 to be in the last drawing. The accuracy of its position directly affects the quality of the final product. Therefore, a more accurate motor adjustment is adopted. Through the position adjustment of the above three places, the three points of the raw material before and after the mold can be ensured to be in a straight line, thereby reducing the damage of the mold and ensuring the drawing quality during the drawing process.

[0047] When the raw material wire directly enters the traction wheel 32, it will slip on the surface of the traction wheel 32. Generally, it is used to wind several times to reduce the slippage, but the multiple coils will be entangled with each other on the surface of the wire separation wheel 33, so it is necessary to pass through the wire separation wheel 33 to separate them. Figure 5 As shown in the figure, the line dividing wheel 33 is installed on the adjustment plate 34 by fixing screws, the adjustment plate 34 is fixed on the line dividing wheel block 35, and the line dividing wheel block 35 is fixed on the sleeve 30; the adjustment plate 34 can change the deflection angle of the three or four wires through the top screw, so as to achieve different line dividing distances; the line dividing wheel block 35 can move forward and backward along the sleeve 30 to change the positional relationship between the line dividing wheel 33 and the traction wheel 32; the traction wheel 32 is fixed to one end of the connecting shaft 31, and the other end of the connecting shaft 31 is connected to the first motor 27 through the coupling 28; the entire adjustment assembly 7 is fixed to the wire drawing machine frame 1 through the guide shaft support 29;

[0048] The raw material wire needs to be drawn seven times before it can become a finished product wire. The tension formed by the raw material wire after each passing through the traction wheel 32 is different, which can easily cause the finished product wire to break before and after the wire drawing die. Therefore, the raw material wire that has passed through the traction wheel must first pass through the tension adjustment mechanism 3 before entering the front guide wheel mechanism 4 to participate in the next die drawing. Figure 6-7 As shown in , the tension sensor 39 obtains the tension value at this position by monitoring the up and down shaking value of the wire guide wheel 41, and feeds back the value to the first motor 27 corresponding to the traction wheel 32, and the first motor 27 adaptively adjusts the speed according to the tension value; when the first motor 27 performs adaptive speed regulation, the swing rod 40 will shake, and at this time, the combination of the spring 38 and the counterweight block 37 will suppress this shaking, so as to realize the smooth operation of the raw material wire on the wire guide wheel 41, and avoid jumping out of the guide wheel, wire breakage, etc.;

[0049] The raw material wire is prone to burrs and splitting before entering the mold, which makes it difficult to pass through the mold. At the same time, due to the high hardness of tungsten wire, simple manual processing is not easy to solve this problem. Therefore, the present invention solves this problem through an electrochemical method, such as Figure 8 As shown in the figure, the wire-making mechanism 9 is composed of an electrode rod 44, a liquid box 43 and an isolating plate 42. The isolating plate 42 is filled with alkaline liquid, and the bottom is connected to a power line to form an electrolyte. The raw material thread head is clamped with metal pliers and placed in the alkaline solution, and is in contact with the electrode rod 44.

[0050] like Fig. 9 As shown in the figure, the wire taking-up mechanism 8 is composed of a wire arrangement guide wheel 45, a wire taking-up assembly 46 and a wire taking-up tension adjustment mechanism 47; the finished wire after drawing passes through the wire taking-up tension adjustment mechanism 47 and the wire arrangement guide wheel 45 in turn and enters the wire taking-up assembly 46; the wire taking-up assembly 46 can perform speed adaptive adjustment according to the value fed back by the wire taking-up tension adjustment assembly 47,

[0051] like Fig.10As shown in the figure, the wire take-up assembly 46 is mainly divided into two parts: winding and arranging. The second motor 48 drives the upper winding part to move forward and backward through the screw rod 49 and the second linear rail 50; the wire take-up assembly 46 is driven to rotate by the winding motor.

[0052] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected.
