Description

Technical Field

[0001] The utility model relates to a highly wear-resistant single crystal wire drawing die, belonging to the technical field of single crystal wire drawing dies. Background Art

[0002] Wire drawing dies usually refer to various dies for drawing metal wires, as well as wire drawing dies for drawing optical fibers. All wire drawing dies have a hole of a certain shape in the center, which can be round, square, octagonal or other special shapes. When the metal is pulled through the die hole, its size becomes smaller and even its shape changes; when drawing soft metals (such as gold and silver), a steel die is sufficient, and there can be multiple holes of different apertures on the steel die; wire drawing dies have a wide range of uses, such as high-precision wire materials used in electronic devices, radars, televisions, instruments and aerospace, as well as commonly used tungsten wires, molybdenum wires, stainless steel wires, wire and cable wires and various alloy wires are all drawn with diamond wire drawing dies. Diamond wire drawing dies use natural diamonds as raw materials, so they have strong wear resistance and extremely high service life.

[0003] In the prior art, for example, the Chinese patent number CN 110529036 A, “A Substation Maintenance Device”, comprises a membrane body, wherein the membrane body comprises an outer mold sleeve, a first mold cover and a second mold cover; a mold core, wherein the mold core is arranged in the middle of the outer mold sleeve; a placement groove is provided on one side of the outer mold sleeve, and two protective slide grooves are provided on the inner wall of one side of the placement groove; the mold core comprises a single crystal module and two sets of connection protection mechanisms, wherein the two sets of connection protection mechanisms are arranged on one side of the single crystal module and are respectively inserted in the two protective slide grooves; the connection protection mechanism comprises a connection slide rod, two damping slide blocks and two reset springs. Its beneficial effect is that the entire wire drawing die is divided into two parts, the membrane body and the mold core, by utilizing the design of the connecting protection mechanism. In this way, the mold core is connected and arranged inside the membrane body through the connecting protection mechanism, and when a large friction force is generated when the diamond wire passes through the mold core, the friction force will drive the single crystal module to slide in the placement groove of the outer mold sleeve. At the same time, through the movement coordination between the damping slider and the reset spring, the restoring force of the reset spring is utilized to reduce the friction force while pushing the single crystal module back to the initial position, so that the entire wire drawing die can be used normally in the subsequent process.

[0004] However, in the prior art, single crystal wire drawing dies are used more and more widely. All wire drawing dies have a hole of a certain shape in the center, which can be round, square, octagonal or other special shapes. The dies are replaced according to the shape of the wire to be drawn. Repeated replacement of the wire drawing dies is troublesome and affects work efficiency. Utility Model Content

[0025] In this embodiment, fixing frames 2 are provided on both sides of the mold 1. The two fixing frames 2 are used to fix the position of the mold 1. Mounting holes 3 are opened at corresponding positions on one side of the mold 1 and the fixing frames 2. The replacement component 4 can be disassembled more conveniently through the mounting holes 3. When it is necessary to replace molds of different shapes for single crystal wire drawing, the two first screws 45 can be rotated to disengage the first screws 45 from the first fixing holes 43. By pulling the limit ring 44, the center columns 41 on both sides can be disengaged from the mounting holes 3, and the center columns 41 with different circular cross-sections 42 can be replaced. There is no need to repeatedly replace the mold 1, which saves time and cost, avoids greater wear on the mold 1 due to frequent replacement, and is simple to disassemble, thereby facilitating the maintenance and repair of the mold by the staff.

[0026] Example 2

[0027] like Figure 1-3 As shown, the utility model proposes a high wear-resistant single crystal wire drawing die. Compared with embodiment 1, this embodiment also includes a stabilizing notch 5 on one side of the mold 1, two stabilizing components 6 are fixed at the upper and lower parts inside the stabilizing notch 5, and the stabilizing component 6 includes two U-shaped blocks 61. The corresponding outer sides of the two U-shaped blocks 61 are fixed to the side walls of the stabilizing notch 5. The U-shaped blocks 61 are provided with two rows of second fixing holes 62. The inner circles of the two rows of second fixing holes 62 are both provided with internal threads 2. The outer sides of each U-shaped block 61 are fixedly connected to a limit clip by two second screws 64. Plate 63, two limiting clamps 63 are arranged in opposite directions, two fixing frames 7 are fixedly installed on one side of the mold 1, and a connecting block 9 is slidably connected to the inner wall of the fixing frame 7. A plurality of third fixing holes 8 are provided on one side of the fixing frame 7, and the inner circle of the third fixing hole 8 is in conflict with the connecting block 9 through a bolt 11. A limiting cotton block 10 is provided at the corresponding inner end of the two connecting blocks 9, and a plurality of lubrication holes 12 are provided on the top of the limiting cotton block 10. The two connecting blocks 9 and the two U-shaped blocks 61 are arranged crosswise, and the curvature of the corresponding inner sides of the two limiting cotton blocks 10 and the two limiting clamps 63 are equal.

[0028] In this embodiment, two stabilizing components 6 are fixed at the upper and lower parts inside the stabilizing slot 5, and the two stabilizing slots 5 are used to better protect the wire drawing die passing through. Two fixing frames 7 are fixedly installed on one side of the die 1, and the inner wall of the fixing frame 7 is slidably connected with a connecting block 9. A plurality of third fixing holes 8 are provided on one side of the fixing frame 7. The inner circle of the third fixing hole 8 is in conflict with the connecting block 9 through a bolt 11. A limiting cotton block 10 is provided at the corresponding inner end of the two connecting blocks 9. When it is necessary to adjust the protection of the thickness of the wire drawing die, the corresponding positions of the two limiting cotton blocks 10 and the two limiting splints 63 can be adjusted. A plurality of lubrication holes 12 are provided on the top of the limiting cotton block 10, and lubricant can be dripped through the lubrication holes 12. The lubricant contacts the passing wire through the limiting cotton block 10, thereby reducing the wear of the hole in the die and improving the quality of the wire drawing product.

[0029] Working principle: When using a highly wear-resistant single crystal wire drawing die, lubricant can be dripped into the lubrication hole 12. The contact between the two limiting cotton blocks 10 and the wire drawing can reduce the wear of the hole in the die. The distance between the two limiting cotton blocks 10 can be adjusted by rotating the two bolts 11. Secondly, the wire will pass through the center position of the two stabilizing components 6. By protecting wires of different thicknesses, the position of the two limiting clamps 63 can be adjusted. The corresponding distance between the two limiting clamps 63 can be adjusted by rotating multiple second screws 64. The two stabilizing components 6 are set to buffer the force applied to the wire drawing, thereby avoiding the problem of the wire being broken. If it is necessary to replace a mold of a different shape for single crystal wire drawing during use, the two first screws 45 can be rotated to disengage the first screws 45 from the first fixing hole 43. By pulling the limiting ring 44, the center columns 41 on both sides can be disengaged from the mounting hole 3. The center columns 41 with different circular cross-sections 42 can be replaced. There is no need to repeatedly replace the mold 1, which saves time and cost, avoids greater wear on the mold 1 due to frequent replacement, and is easy to disassemble.

[0030] The above are only preferred implementations of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
