Description

Technical Field

[0001] This utility model relates to the technical field of tungsten electrode wire drawing equipment, specifically, to a tungsten electrode wire drawing device. Background Technology

[0002] Tungsten electrode wire drawing is a metal processing technique primarily used to process tungsten raw materials into tungsten wires of specific diameters and shapes. Due to its high melting point, high hardness, good high-temperature strength, and electrical conductivity, tungsten is widely used in electronics, lighting, welding, and other fields, and the drawn tungsten wire is a key material for these applications.

[0003] Generally, tungsten raw materials are first made into suitable blanks, and then drawn using tools such as wire drawing dies, gradually becoming thinner and longer as they pass through the die holes, thus achieving the required diameter and dimensional accuracy. During this process, it is necessary to precisely control parameters such as drawing force, speed, and temperature to ensure the quality of the tungsten wire. Traditional wire drawing devices mostly use simple mechanical grippers to hold the tungsten wire, and after drawing, it also needs to be wound. To complete the winding and drawing processes simultaneously, a tungsten electrode wire drawing device was designed. Utility Model Content

[0004] This utility model provides a tungsten electrode wire drawing device, which includes a trapezoidal slide groove and a trapezoidal slide rod, as well as a wire drawing clamp with an arc-shaped placement groove. The clamping distance can be adjusted according to the thickness of the tungsten wire, making it suitable for various specifications of tungsten wire and facilitating the drawing operation of the tungsten wire.

[0005] A tungsten electrode wire drawing device includes a base, a first electric push rod fixedly connected to the upper side of the base, a connecting cavity fixedly provided at the upper end of the telescopic rod of the first electric push rod, a square ring fixedly provided on the upper side of the connecting cavity, I-shaped connecting blocks fixedly connected to both ends of the square ring, the upper ends of the two I-shaped connecting blocks fixedly connected to the lower sides of a fixing block, the fixing block being U-shaped, trapezoidal sliding grooves provided on the upper part of one side of the two vertical rods of the fixing block, trapezoidal sliding rods of one side of a wire drawing clamp block slidably fitted in the trapezoidal sliding grooves, and arc-shaped placement grooves provided on the opposite side of the wire drawing clamp block.

[0007] As a further limitation of this technical solution, it also includes a winding assembly, which includes a fixed base, a support column, a winding wheel support shaft, and a servo motor. The central shaft of the winding wheel support shaft is rotatably connected to the upper end of the support column. The support column fixes the fixed base and the servo motor.

[0008] As a further limitation of this technical solution, the surface of the winding wheel support shaft is covered with a rubber layer, and the winding wheel support shaft can be inserted into the central hole of the winding wheel.

They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0020] The following is in conjunction with the appendix Figures 1-4 The present invention will be further described in terms of the embodiments and implementation methods.

[0021] The specific embodiments of this utility model are as follows:

[0022] A tungsten electrode wire drawing device includes a base 4. A first electric push rod 3 is fixedly connected to the upper side of the base 4. A connecting cavity 2 is fixedly provided at the upper end of the telescopic rod of the first electric push rod 3. A square ring 16 is fixedly provided on the upper side of the connecting cavity 2. I-shaped connecting blocks 12 are fixedly connected to both ends of the square ring 16. The upper ends of the two I-shaped connecting blocks 12 are fixedly connected to the lower sides of the fixing block 10. The fixing block 10 is U-shaped. A trapezoidal sliding groove is provided on the upper part of one side of the two vertical rods of the fixing block 10. A trapezoidal sliding rod on one side of the wire drawing clamp 9 is slidably fitted in the trapezoidal sliding groove. An arc-shaped placement groove 901 is provided on the opposite side of the wire drawing clamp 9.

[0023] The other side of the wire-drawing clamp 9 is rotatably connected to one end of the swing rod 11. The swing rod 11 is V-shaped. The lower end of the swing rod 11 is rotatably connected to one end of the connecting rod 13. One end of each connecting rod 13 is rotatably connected to one side end of the moving block 15. The middle part of each swing rod 11 is rotatably connected to the lower part of the vertical rod of the corresponding fixed block 10. The lower side of the moving block 15 is fixedly connected to the telescopic rod of the second electric push rod 14. The second electric push rod 14 is fixedly installed in the connecting cavity 2.

[0024] It also includes a winding assembly, which includes a fixed base 5, a support column 6, a winding wheel support shaft 7 and a servo motor 8. The central shaft of the winding wheel support shaft 7 is rotatably connected to the upper end of the support column 6. The support column 6 fixes the fixed base 5 and the servo motor 8. The output shaft of the servo motor 8 is fixed to one end of the central shaft of the winding wheel support shaft 7.

[0025] The surface of the winding wheel support shaft 7 is covered with a rubber layer. The winding wheel support shaft 7 can be inserted into the center hole of the winding wheel. The rubber layer undergoes elastic deformation to support the winding wheel.

[0026] In this embodiment, the movement of the telescopic rod of the second electric push rod 14 can drive the movement of the moving block 15, the moving block 15 can drive the connecting rod 13 to swing, the connecting rod 13 can drive the swing rod 11 to swing, and the swing rod 11 can drive the trapezoidal slide rod of the wire drawing clamp 9 to move in the trapezoidal slide groove.

[0027] Initially, the wire drawing clamp 9 allows the tungsten wire blank 1 to pass through. After the tungsten wire blank 1 passes through, the extension rod of the second electric push rod 14 is controlled to move so that the wire drawing clamp 9 clamps the tungsten wire blank 1, pulling the outer end of the tungsten wire 1 outward along the arc-shaped placement groove 901 of the wire drawing clamp 9. During this process, the wire drawing clamp 9 is controlled to gradually approach until they are in contact, drawing the tungsten wire blank 1 to a suitable diameter. The outer end of the drawn tungsten wire is wound around the winding wheel. The servo motor 8 is started to drive the winding wheel support shaft 7 to rotate, thereby winding the tungsten wire. Under the action of the winding wheel rotation driven by the winding wheel support shaft, the tungsten wire blank 1 is drawn into a tungsten wire and wound around the winding wheel after passing between the wire drawing clamps 9. The tungsten wire blank 1 is drawn into an electrode wire of a suitable diameter after being limited by the wire drawing clamp 9.

[0028] The method of using this utility model is as follows: Place the tungsten wire blank 1 to be drawn between the wire drawing clamps 9 in the initial state, ensuring that the tungsten wire blank 1 can pass smoothly through the wire drawing clamps 9. Start the second electric push rod 14 to control its telescopic rod to move, driving the moving block 15 to move. The moving block 15 causes the swing rod 11 to swing through the connecting rod 13, thereby driving the trapezoidal slide rod of the wire drawing clamp 9 to move in the trapezoidal slide groove, so that the wire drawing clamp 9 gradually approaches and clamps the tungsten wire blank 1, pulling the outer end of the tungsten wire blank 1, so that it is pulled outward along the arc-shaped placement groove 901 of the wire drawing clamp 9. During the pulling process, the second electric push rod 14 is continuously controlled to gradually bring the wire-drawing clamp 9 closer together until they are in contact, drawing the tungsten wire blank 1 to a suitable diameter. The outer end of the drawn tungsten wire is then wound onto the winding wheel. The servo motor 8 is activated, and its output shaft drives the winding wheel support shaft 7 to rotate. The winding wheel support shaft 7 is tightly fitted with the winding wheel through a rubber layer, driving the winding wheel to rotate and thus winding the tungsten wire. During the winding process, the rotation speed and rotation angle of the servo motor 8 are adjusted according to the required winding speed and tension to ensure that the tungsten wire is evenly wound onto the winding wheel. As the tungsten wire 1 rotates and winds on the winding wheel, it gradually passes through the wire-drawing clamp 9. Under the constraint of the wire-drawing clamp 9, the tungsten wire blank is drawn and shaped, achieving a process of simultaneous winding and drawing.

[0029] In other embodiments, the tungsten wire can also be wound around the winding assembly after passing through a pull-out device (existing technical means will not be described in detail here).

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
