Description

Technical Field

[0001] The invention relates to a metal drawing equipment structure technology, and more specifically to a rotary linear chain wire drawing machine and a wire drawing process thereof. Background Art

[0002] In the prior art, two main methods are usually used to produce thick tungsten wire in the tungsten wire processing industry, namely, a large turntable wire drawing machine and a chain linear drawing machine.

[0003] First of all, the working principle of the large turntable wire drawing machine is to draw the lubricated and heated tungsten wire through the wire drawing die, and then directly wind it on the wire winding turntable. The main advantage of this method is that it can complete the drawing and wire winding process relatively quickly, which is theoretically suitable for mass production. However, this method is prone to wire breakage due to uneven tension during the winding process, especially when the wire drawing speed is high or the tungsten wire diameter is large. Wire breakage not only reduces production efficiency, but may also lead to unstable product quality.

[0004] Secondly, the chain-type linear stretching machine heats the lubricant-coated tungsten wire and then uses pliers to stretch it along a linear track. Compared with the large turntable wire drawing machine, this method avoids the problem of wire breakage caused by wire winding, thereby improving the quality of the wire to a certain extent. However, the chain-type linear stretching machine occupies a large area, and the production process is reciprocating. The position of the tungsten wire after the mold is unstable, which not only affects the uniformity and diameter accuracy of the wire, but also limits the production efficiency. More importantly, this method cannot achieve stable and continuous production like the disc-type production equipment, especially when producing large-diameter or heavyweight tungsten wires.

[0005] In view of these defects of the prior art, there is an urgent need for a new type of wire drawing machine and wire drawing process, which can not only overcome the problem of easy wire breakage in the large turntable wire drawing machine, but also solve the problems of large footprint, low production efficiency and unstable position of the wire after passing the mold of the chain linear stretching machine. Summary of the invention

[0011] Preferably, the plurality of high-pressure air pliers are distributed around the waist-shaped track at equal intervals.

[0012] Preferably, each of the high-pressure cylinders comprises a cylinder body and a piston rod, the cylinder body is connected to a high-pressure gas source, and the high-pressure gas is used to push the piston rod to drive the clamping portion to open and close.

The entire equipment adopts a linear layout, arranging the wire drawing machine body, chain rotary machine and take-up reel in sequence, and the floor space is much smaller than the traditional chain linear stretching machine, which effectively solves the problem of the latter's wide floor space and scattered production lines.

DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention belong to the present invention.

[0030] In addition, described feature, structure or characteristic can be combined in one or more embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present application. However, those skilled in the art will appreciate that the technical scheme of the present application can be put into practice without one or more of the specific details, or other methods, components, devices, steps, etc. can be adopted. In other cases, known methods, devices, realizations or operations are not shown or described in detail to avoid blurring the various aspects of the application.

[0031] See also Figure 1-5The present embodiment provides a rotary linear chain wire drawing machine, comprising a wire drawing machine body 1, a chain rotary machine 2 and a vertical wire take-up drum 3. The wire drawing machine body 1 comprises a lubricant tank 11, a natural gas heating furnace 12 and a die frame 13, and the tungsten wire 4 passes through the lubricant tank 11, the natural gas heating furnace 12 and the die frame 13 in sequence, ensuring that the tungsten wire 4 obtains sufficient lubrication and suitable temperature conditions before stretching, thereby reducing friction and thermal damage during stretching, and improving the surface quality and ductility of the tungsten wire 4.

[0032] See also Figure 4 The lubricant groove 11 is used to coat the lubricant on the surface of the tungsten wire 4, in order to reduce the friction between the tungsten wire 4 and the die during the stretching process, prevent the tungsten wire 4 from breaking, and improve the stretching efficiency. The natural gas heating furnace 12 is used to heat the tungsten wire 4 coated with lubricant to a certain temperature. This step enables the tungsten wire 4 to reach an ideal plastic state before stretching, which helps to improve the forming effect of the stretching process and prevent excessive cold work hardening of the wire. The die frame 13 is provided with a drawing die for stretching the tungsten wire 4. The tungsten wire 4 is initially formed through the die frame 13. This link is crucial to the diameter and shape accuracy of the tungsten wire 4.

[0033] The chain rotary machine 2 includes a base 21 and a plurality of high-pressure air pliers 22 that reciprocate in a waist-shaped track, and its configuration is intended to achieve continuous and stable stretching of the tungsten wire 4, while the design of the waist-shaped track helps maintain the linearity of the stretching process and reduce material deformation and stress concentration. The waist-shaped track is a path composed of two straight segments and two semicircular curved segments.

[0034] The high-pressure air pliers 22 include a high-pressure cylinder 221 and a clamping part 222 driven by the high-pressure cylinder 221, wherein the clamping part 222 clamps the tungsten wire 4 for linear stretching when the waist-shaped track is in a straight line section adjacent to the mold frame 13. The high-pressure cylinder 221 can achieve precise control of the clamping force during the wire drawing process, ensuring the uniformity and stability of the tungsten wire 4 during stretching, and reducing the risk of wire breakage during the wire drawing process. Finally, the vertical take-up reel 3 is used to collect the stretched tungsten wire 4. This design allows for efficient wire-taking operations, ensuring that the stretched tungsten wire 4 can be arranged in an orderly manner, preventing the tungsten wires 4 from being entangled with each other and deformation caused by stretching, thereby improving the quality of the final product.

[0035] See also Figure 1-2In this embodiment, two wire drawing machine bodies 1 and two chain rotary machines 2 are included. The tungsten wire 4 passes through the first wire drawing machine body 1, the first chain rotary machine 2, the second wire drawing machine body 1 and the second chain rotary machine 2 in sequence to achieve two-stage stretching of the tungsten wire 4. The tungsten wire 4 is first preliminarily stretched in the first wire drawing machine body 1 to form the basic size and improve the mechanical properties of the material. Then, continuous linear stretching is performed in the first chain rotary machine 2 to maintain the linearity of the tungsten wire 4 and reduce internal stress. Next, further processing is performed in the second wire drawing machine body 1 for size reduction and fine drawing. Finally, the final stretching is performed in the second chain rotary machine 2 to ensure high-precision size and optimized physical properties.

[0036] See also Figure 3 and Figure 5 The clamping part 222 of the high-pressure air pliers 22 is equipped with an upper chuck 223 and a lower chuck 224, wherein the upper chuck 223 is installed on the lower side of the high-pressure cylinder 221 and can be adjusted and moved in the vertical direction, and the lower chuck 224 is fixed in the vertical direction and moves synchronously with the upper chuck 223 along the waist-shaped track. The fixedness of the lower chuck 224 is combined with the dynamic adjustment of the upper chuck 223, so that the entire clamping mechanism can adapt to the waist-shaped track movement while maintaining the stability of the tungsten wire 4 during the stretching process. The upper chuck 223 and the lower chuck 224 are driven by the high-pressure cylinder 221 to achieve relative movement, so as to clamp or release the tungsten wire 4. The clamping force of the tungsten wire 4 is precisely controlled by pneumatic control, which can not only efficiently clamp the tungsten wire 4 for stretching, but also easily release it when necessary, thereby improving the flexibility and efficiency of operation.

[0037] Furthermore, the high-pressure air pliers 22 are fixedly connected to a bracket 23, and the bracket 23 is equipped with a driving device to drive the high-pressure air pliers 22 to move along the waist-shaped track, ensuring that the high-pressure air pliers 22 can move smoothly along a specific path, thereby achieving uniform treatment of the tungsten wire 4 during the entire drawing process. Through the use of the driving device, the position and speed of the high-pressure air pliers 22 can be accurately controlled to improve the accuracy and efficiency of the wire drawing process. Multiple high-pressure air pliers 22 are distributed around the waist-shaped track at equal intervals to evenly distribute the wire drawing force to avoid the breakage or uneven quality of the tungsten wire 4 caused by excessive local force. Each of the high-pressure cylinders 221 includes a cylinder body 225 and a piston rod 226. The cylinder body 225 is connected to a high-pressure gas source, and the high-pressure gas is used to push the piston rod 226 to drive the opening and closing of the clamping part 222. The power of high-pressure gas is used to achieve fast and accurate clamping action, so that the clamping part 222 can quickly clamp or release the tungsten wire 4 when needed, which is very critical to improving the response speed and operational flexibility of the wire drawing machine. In addition, the design of the high-pressure cylinder 221 also ensures the stability and adjustability of the clamping force during the wire drawing process, further ensuring the quality control of the tungsten wire 4 processing process.

[0038] The pneumatic control system of the high-pressure air pliers 22 can provide more precise control than the mechanical drive system, especially in the adjustment of the clamping force and the clamping position, which provides a guarantee for high-quality wire drawing. In addition, the response speed of the pneumatic system far exceeds that of the mechanical system, which means that the technical solution of this embodiment has greater flexibility and efficiency in adjusting the wire drawing speed and adaptability to tungsten wires 4 of different diameters. Since the high-pressure air pliers 22 do not rely on friction to drive the drawing of the tungsten wire 4, but through direct force control, it can more effectively protect the material and reduce wear and breakage during the wire drawing process, thereby improving the overall quality of the product. Compared with complex mechanical drive systems, the pneumatic system structure is simpler, maintenance is easier, and the reliability and stability of the system are also improved.

[0039] The vertical take-up drum 3 includes a cylindrical take-up drum and a driving device. The cylindrical design allows the tungsten wire 4 to be evenly wound on the take-up drum to avoid crossing and entanglement during the winding process. A take-up opening is provided on the side of the take-up drum. The width of the take-up opening is greater than the diameter of the tungsten wire 4, so that the tungsten wire 4 can smoothly pass through and be wound on the outer peripheral surface of the take-up drum body. The driving device includes a driving motor and a reduction mechanism that is transmission-connected to the take-up drum body, which is used to drive the take-up drum body to rotate to wind up the tungsten wire 4. By using the driving motor and the reduction mechanism, the rotation speed of the take-up drum can be accurately controlled to ensure that the tungsten wire 4 is evenly wound at an appropriate speed, thereby avoiding excessive tension during the winding process and affecting the quality of the tungsten wire 4.

[0040] The driving device also includes a tension detection device and a controller, which detects the tension of the tungsten wire 4 and controls the speed of the driving motor and the reciprocating speed of the high-pressure air clamp 22, so as to keep the winding tension of the tungsten wire 4 within a reasonable range. This setting realizes real-time monitoring and automatic adjustment of the tension of the tungsten wire 4, and ensures the stability of the tension of the tungsten wire 4 during the entire winding process by adjusting the matching of the winding speed and the drawing speed, which is crucial to ensure the dimensional accuracy and mechanical properties of the final tungsten wire 4 product.

[0041] Another embodiment of the present invention describes a wire drawing process based on the above-mentioned rotary linear chain wire drawing machine, comprising the following steps:

[0042] S1, immersing the tungsten wire 4 into the lubricant tank 11, so that a layer of lubricant is coated on the surface of the tungsten wire 4;

[0043] Through the above steps, the friction between the tungsten wire 4 and the wire drawing die during the wire drawing process is reduced, the surface of the tungsten wire 4 is protected, and smooth wire drawing is ensured.

[0044] S2, conveying the lubricant-coated tungsten wire 4 to the natural gas heating furnace 12 and heating it to a suitable temperature;

[0045] This step softens the tungsten wire 4 by heating, reduces its hardness, makes it easier to draw, and improves the efficiency and quality of wire drawing.

[0046] S3, the tungsten wire 4 after heat treatment first passes through the wire drawing die set in the main body of the first wire drawing machine, and is initially stretched by the clamping part 222 of the high-pressure air clamp 22 of the first chain rotary machine to achieve the initial size forming of the tungsten wire 4;

[0047] This step is a key step in forming the basic outline of the tungsten wire 4, and the preliminary specifications of the tungsten wire 4 are established through preliminary stretching.

[0048] S4, the tungsten wire 4 after preliminary stretching passes through the second wire drawing machine body again, repeats the lubrication of step S1 and the heating of step S2, the tungsten wire 4 after heat treatment first passes through the wire drawing die set in the second wire drawing machine body, and then enters the second chain rotary machine, and the tungsten wire 4 is stretched for the second time to refine the size and improve its physical properties;

[0049] This step further fine-tunes the diameter and strength of the tungsten wire 4 and further improves the physical and mechanical properties of the tungsten wire 4 through secondary stretching.

[0050] S5. After the secondary stretching is completed, the tungsten wire 4 is guided to the vertical take-up drum 3, enters through the set take-up port, and is evenly wound and collected on the cylindrical take-up drum body of the vertical take-up drum.

[0051] The last step ensures that the stretched tungsten wire 4 can be neatly collected, preventing entanglement and uneven force between the tungsten wires 4, and maintaining the quality of the tungsten wire 4. It can be seen that the entire process is carefully designed, from lubrication to heating, to multi-stage stretching, each step is aimed at ensuring the quality and performance of the tungsten wire 4, and ultimately achieving stable production of high-quality tungsten wire 4.

[0052] Furthermore, during the winding process, the tension of the tungsten wire 4 is continuously monitored by a tension detection device, and the speed of the winding reel and the reciprocating speed of the high-pressure air pliers are adjusted by a controller to keep the winding tension of the tungsten wire 4 constant. The purpose of this step is to ensure the consistency of the tension of the tungsten wire 4 during the winding process, to avoid deformation or breakage of the tungsten wire 4 due to uneven tension, and thus to improve the quality and consistency of the final product. By precisely controlling the winding speed and the movement speed of the high-pressure air pliers, the tension of the tungsten wire 4 can be precisely adjusted, ensuring that the entire winding process proceeds smoothly, and finally obtaining a tungsten wire 4 that meets high standards.

[0053] In summary, the present invention proposes a rotary linear chain wire drawing machine and its wire drawing process, aiming to improve the efficiency, precision and product quality in the production process of tungsten wire 4. The high-pressure air pliers 22 clamping technology in the present invention utilizes the upper and lower clamping heads driven by the high-pressure cylinder 221, which not only realizes the precise clamping and loosening of the tungsten wire 4, but also ensures the continuity and linearity of the wire drawing process through the design of the waist-shaped track, effectively reducing the internal stress of the tungsten wire 4 caused by the turning, thereby reducing the possibility of wire breakage and improving the reliability of the product. In addition, the present invention adopts a two-stage stretching strategy, combined with the configuration of two wire drawing machine bodies 1 and two chain rotary machines 2, to ensure that the transition of the tungsten wire 4 from preliminary stretching to fine stretching is smooth and seamless, greatly improving the stretching efficiency while ensuring the stability of the wire drawing process and the uniformity of the tungsten wire 4. Furthermore, the vertical take-up reel 3 design of the present invention, in conjunction with the advanced tension detection and control system, not only ensures the smoothness of the winding process and the consistency of the winding tension of the tungsten wire 4, but also optimizes the entire winding process by precisely regulating the winding speed and the reciprocating speed of the high-pressure air clamp 22, thereby ensuring the dimensional accuracy and surface quality of the tungsten wire 4. Through the above innovative design and process optimization, the present invention has significant innovation and practical value in the field of tungsten wire 4 manufacturing.

It is easy to understand that the processes shown in the above figures do not indicate or limit the time sequence of these processes. In addition, it is also easy to understand that these processes can be performed synchronously or asynchronously, for example, in multiple modules.

[0055] It should be understood that the present application is not limited to the precise structures that have been described above and shown in the drawings, and that various modifications and changes may be performed without departing from the scope thereof.
