Description

Technical Field

[0001] The present invention relates to the technical field of titanium alloy wire processing, and particularly relates to a drawing device for titanium alloy wire. Background Art

[0002] Titanium alloy wire is a slender titanium alloy wire made by drawing titanium alloy materials through a drawing process. Titanium alloy wire has excellent properties such as high strength and corrosion resistance, and is widely used in various fields. During the process of drawing titanium alloy wire, the titanium alloy wire needs to pass through lubricating powder before passing through the drawing die. By wrapping a layer of lubricating powder on the surface of the titanium alloy wire, the friction between the titanium alloy wire and the die is reduced, and the direct contact between the titanium alloy wire and the die is reduced, thereby reducing the energy consumption during the drawing process. In the existing production process, the titanium alloy wire is only passed through a box filled with lubricating powder, which cannot ensure the adhesion effect of the lubricating powder on the titanium alloy wire. Moreover, during use, although the position of the titanium alloy wire in the lubricating powder is relatively stable, the lubricating powder at the position of the titanium alloy wire is continuously consumed and the lubricating powder does not flow. If the lubricating powder cakes or gets damp, a cavity will be formed at the position of the titanium alloy wire, reducing the amount of lubricating powder adhered to the titanium alloy wire and affecting the lubrication effect. Therefore, a drawing device for titanium alloy wire is needed to solve the above problems. Summary of the Invention

Detailed implementation mode

[0034] The above solution is further described below in conjunction with specific embodiments. It should be understood that these embodiments are for illustrating the present application and not for limiting the scope of the present application. The implementation conditions adopted in the embodiments can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0035] Before passing through the wire drawing die, the titanium alloy wire needs to pass through lubricating powder, and a layer of lubricating powder is wrapped on the surface of the titanium alloy wire to reduce the friction between the titanium alloy wire and the die, reduce the direct contact between the titanium alloy wire and the die, thereby reducing the energy consumption during the wire drawing process. In the existing process, the titanium alloy wire is only passed through a box filled with lubricating powder, and the adhesion effect of the titanium alloy wire cannot be guaranteed.

[0036] Embodiment 1: A wire drawing device for titanium alloy wire, as Figures 1-5As shown in the figure, it includes a workbench 1. On the left side of the workbench 1, an installation box 11 is fixedly connected. Inside the installation box 11, a storage shell 12 is fixedly connected. A vibration module is arranged on the storage shell 12, and the vibration module is used to vibrate the storage shell 12. On the right side of the installation box 11, a wire drawing die 121 is detachably connected. When the titanium alloy wire passes through the wire drawing die 121, the wire drawing die 121 stretches the titanium alloy wire. In the middle of the workbench 1, a drawing wheel 122 is arranged. The drawing wheel 122 is an existing mechanism, and the drawing wheel 122 drives the alloy wire to move to the right through its own rotation. A powder feeding shell 13 is fixedly connected between the installation box 11 and the storage shell 12. Initially, the storage shell 12 is filled with lubricating powder. On the rear side of the powder feeding shell 13, there is an inclined plane. On the left side of the installation box 11, a rotating column 14 is rotatably connected. On the left side of the installation box 11, a power component is arranged for driving the rotating column 14 to rotate. On the right side of the rotating column 14, an auger 15 is fixedly connected. The auger 15 is located inside the installation box 11. On the right side of the storage shell 12, a fixed pipe 16 is fixedly connected and communicated. The right side of the auger 15 is rotatably connected to the fixed pipe 16. During the rotation of the auger 15, the lubricating powder in the powder feeding shell 13 is driven to move to the right. On the upper right side of the storage shell 12, there is a hole, and a sealing cover 17 which is slidably connected with the hole on the storage shell 12 is provided for sealing cooperation.

[0037] As Figures 3-5 shown, the storage shell 12 is fixedly connected with a first fixing frame 18. On the lower side of the first fixing frame 18, two symmetrically distributed limiting columns 19 are fixedly connected. The two symmetrically distributed limiting columns 19 are both slidably connected with the sealing cover 17. The limiting columns 19 are used to limit the sliding of the sealing cover 17, so that the sealing cover 17 can only slide up and down. Between the sealing cover 17 and the first fixing frame 18, two symmetrically distributed springs 110 are fixedly connected. The springs 110 are used to reset the sealing cover 17. On the left side of the installation box 11, a first sealing sleeve 111 is fixedly connected and communicated. The first sealing sleeve 111 is a hollow frustum made of rubber material.

[0038] As Figure 3 and Figure 6 shown, the power component includes a second fixing frame 2. The second fixing frame 2 is fixedly connected to the left side of the installation box 11. The second fixing frame 2 is rotatably connected with a fixed roller 21. On the left side of the installation box 11, a first rotating shaft 22 is rotatably connected. The fixed roller 21 and the first rotating shaft 22 are driven by a belt and pulley. The first rotating shaft 22 and the rotating column 14 are driven by a bevel gear set. On the rear side of the second fixing frame 2, two symmetrically distributed sliding plates 24 are slidably connected. Between the two symmetrically distributed sliding plates 24, a sliding roller 23 is rotatably connected. Between the sliding plate 24 and the second fixing frame 2, a first elastic member 25 is fixedly connected. The first elastic member 25 is an elastic drawstring, which is used to drive the sliding plate 24 to move forward. Inside the installation box 11, a pre-extrusion component is arranged, and the pre-extrusion component is used to extrude the titanium alloy wire.

[0039] As Figure 3 andFigures 7-9 As shown, the pre-extrusion assembly includes a fixed housing 3. The fixed housing 3 is fixedly connected inside the mounting box 11. The fixed housing 3 is located on the right side of the storage housing 12. The fixed housing 3 is cylindrical. Three sets of hydraulic telescopic rods 31 are arranged inside the fixed housing 3. Each set of hydraulic telescopic rods 31 has two symmetrically distributed ones. The telescopic ends of the three sets of hydraulic telescopic rods 31 all face the inside of the fixed housing 3. The adjacent two sets of hydraulic telescopic rods 31 are staggered. The telescopic end of the hydraulic telescopic rod 31 is fixedly connected with a third fixing frame 32. The third fixing frame 32 is rotatably connected with an extrusion wheel 33. The left side of the fixed housing 3 is fixedly connected and communicated with a second sealing sleeve 34. The second sealing sleeve 34 is a hollow frustum made of rubber. The fixed housing 3 is fixedly connected with a connecting member 35. The connecting member 35 is composed of three annular pipes connected. The connecting member 35 is communicated with all three sets of hydraulic telescopic rods 31. The connecting member 35 is fixedly connected and communicated with a conduit 36. The conduit 36 is communicated with an external hydraulic system, used to provide hydraulic oil for the hydraulic telescopic rod 31 and control the telescopic movement of the telescopic end of the hydraulic telescopic rod 31.

[0040] As Figure 8 and Figure 9 shown, a first limiting member 4 is sealingly and slidably connected to the upper hydraulic telescopic rod 31 of the rightmost set of hydraulic telescopic rods 31. The first limiting member 4 is fixedly connected to the telescopic part of the adjacent hydraulic telescopic rod 31. When the telescopic end of the hydraulic telescopic rod 31 moves, the first limiting member 4 moves synchronously. The fixed housing 3 is fixedly connected with a limiting plate 41. A pressure sensor is arranged on the limiting plate 41. The pressure sensor is electrically connected to an external hydraulic system. The first limiting member 4 is in extrusion fit with the pressure sensor on the limiting plate 41. When the telescopic end of the upper right hydraulic telescopic rod 31 moves downward, the first limiting member 4 presses the pressure sensor on the limiting plate 41. The pressure sensor transmits an electrical signal to the hydraulic system to control the hydraulic system to close. A second limiting member 42 is sealingly and slidably connected to the lower right hydraulic telescopic rod 31. The second limiting member 42 is fixedly connected to the telescopic part of the adjacent hydraulic telescopic rod 31. The second limiting member 42 is in limiting cooperation with the adjacent hydraulic telescopic rod 31. During use, the second limiting member 42 restricts the movement of the hydraulic telescopic rod 31. A detection mechanism is arranged on one side of the mounting box 11 close to the wire drawing die 121. The detection mechanism is used to detect the state of the wire drawing die 121.

[0041] As Figure 10 and Figure 11As shown in the figure, the detection mechanism includes two fixing plates 5 symmetrically distributed up and down. The two fixing plates 5 symmetrically distributed up and down are fixedly connected to the right side of the installation box 11. The fixing plate 5 is rotatably connected to a rotating plate 51. A second elastic member 52 is fixedly connected between the fixing plate 5 and the installation box 11. The second elastic member 52 is an elastic drawstring. The installation box 11 is fixedly connected with a limiting block 53 that is in contact and cooperation with the two symmetrically distributed rotating plates 51. Notches are provided between the symmetrically distributed rotating plates 51. A position sensor is provided on the rotating plate 51, and this position sensor is used to detect the distance between itself and the installation box 11. On the side of the installation box 11 away from the second fixing frame 2, symmetrically distributed fourth fixing frames 54 are fixedly connected. The fourth fixing frame 54 is rotatably connected with a limiting roller 55.

[0042] During the process of using this device to draw titanium alloy wire, first pass the titanium alloy wire through the gap between the fixed roller 21 and the sliding roller 23, the first sealing sleeve 111, the storage shell 12, the second sealing sleeve 34, the fixed shell 3, between the two rotating plates 51, the wire drawing die 121 and the two limiting rollers 55, and then wind the titanium alloy wire around the drawing wheel 122. Rotate the drawing wheel 122 to pull the titanium alloy wire, so that the titanium alloy wire passes through the wire drawing die 121. Extrude the titanium alloy wire through the wire drawing die 121 to make the titanium alloy wire thinner.

[0043] During the process of the titanium alloy wire passing through the gap between the fixed roller 21 and the sliding roller 23, the titanium alloy wire extrudes the sliding roller 23 to move backward. During the backward movement of the sliding roller 23, the upper and lower sliding plates 24 are driven to slide backward. The sliding plate 24 pulls the first elastic member 25 to elongate. By extruding the titanium alloy wire with the sliding roller 23, the titanium alloy wire is brought into contact with the fixed roller 21 and the sliding roller 23. During the process of the titanium alloy wire moving to the right, the titanium alloy wire drives the fixed roller 21 to rotate clockwise (viewed from top to bottom). The fixed roller 21 drives the first rotating shaft 22 to rotate. The first rotating shaft 22 drives the rotating column 14 to rotate clockwise (viewed from left to right) through the bevel gear set. The rotating column 14 drives the auger 15 to rotate. Initially, the storage shell 12 and the powder inlet shell 13 are filled with lubricating powder. During the rotation of the auger 15, the auger 15 drives the lubricating powder on the powder inlet shell 13 to move to the right. The lubricating powder enters the storage shell 12 through the fixed pipe 16, extrudes the lubricating powder in the storage shell 12, so that the titanium alloy wire is in full contact with the lubricating powder and keeps a certain pressure on the lubricating powder in the storage shell 12.

[0044] During the rotation of the rotating column 14, the lubricating powder on the powder inlet shell 13 gradually enters the storage shell 12. The vibration module on the storage shell 12 is activated to vibrate the lubricating powder. The amount of lubricating powder adhered to the titanium alloy wire during its movement is less than the amount of lubricating powder entering the storage shell 12. The lubricating powder in the storage shell 12 presses against the sealing cover 17. When the pressure of the lubricating powder can overcome the two springs 110, the lubricating powder presses the sealing cover 17 to move upward. The sealing cover 17 presses the two springs 110 upward. The sealing cover 17 moves upward under the limitation of the limiting column 19 and opens the hole on the upper side of the storage shell 12, so that part of the lubricating powder is discharged from the hole on the upper side of the storage shell 12 and then slides into the powder inlet shell 13, enabling the continuous circulation of the lubricating powder in the storage shell 12 and the powder inlet shell 13, improving the fluidity of the lubricating powder, and preventing some of the lubricating powder from caking under long-term extrusion. When the lubricating powder in the powder inlet shell 13 decreases, the staff replenishes the lubricating powder in the powder inlet shell 13.

[0045] During the initial rightward movement of the titanium alloy wire, the staff activates the external hydraulic system. The hydraulic system injects hydraulic oil into the conduit 36. The hydraulic oil enters the six hydraulic expansion rods 31 in three groups through the connecting member 35. The telescopic ends of the hydraulic expansion rods 31 drive the adjacent third fixing frames 32 to move towards the middle of the fixed shell 3. The third fixing frames 32 drive the extrusion wheels 33 to extrude the titanium alloy wire. During the injection of hydraulic oil, the six extrusion wheels 33 simultaneously extrude the titanium alloy wire. The telescopic ends of the two hydraulic expansion rods 31 on the right continuously move. When the telescopic end of the upper right hydraulic expansion rod 31 moves downward, it drives the limiting plate 41 to move downward. When the telescopic end of the lower right hydraulic expansion rod 31 moves downward, it drives the second limiting member 42 to move upward. During the upward movement of the second limiting member 42, the second limiting member 42 gradually contacts the bottom end of the lower right hydraulic expansion rod 31, and the second limiting member 42 stops moving. Consequently, the telescopic end of the lower right hydraulic expansion rod 31 stops moving. During the downward movement of the first limiting member 4, it gradually contacts the limiting plate 41 and presses the pressure sensor on the limiting plate 41. The pressure sensor transmits a signal to the hydraulic system to stop injecting hydraulic oil into the conduit 36. At this time, the second limiting member 42 contacts the bottom end of the lower right hydraulic expansion rod 31, and the two extrusion wheels 33 on the right extrude the titanium alloy wire to the set width. Through the gradual extrusion of the three groups of extrusion wheels 33, the titanium alloy wire becomes thinner. The pressures of the three groups of extrusion wheels 33 are the same, uniformly extruding the titanium alloy wire, enabling the titanium alloy wire to be uniformly stressed and preventing the titanium alloy wire from being damaged. The final width of the titanium alloy wire is controlled by the first limiting member 4.

[0046] During the process of the extrusion wheel 33 extruding the titanium alloy wire, the extrusion wheel 33 makes the lubricating powder and the titanium alloy wire fit tightly. Then the titanium alloy wire passes through two rotating plates 51 and finally through the wire drawing die 121. The titanium alloy wire that meets the specifications is obtained through the wire drawing die 121. The titanium alloy wire is pre-extruded by the extrusion wheel 33 to reduce the wear of the wire drawing die 121. By making the lubricating powder fit with the titanium alloy wire during the extrusion process, the lubrication effect of the titanium alloy wire is improved, and thus the drawing quality of the titanium alloy wire is improved.

[0047] During the process of wire drawing using the wire drawing die 121, if the wire drawing die 121 is damaged and has a notch, when the titanium alloy wire passes through the wire drawing die 121, the wire drawing die 121 will scrape the surface of the titanium alloy wire, peeling off part of the epidermis of the titanium alloy wire from the titanium alloy wire and accumulating it on the left side of the wire drawing die 121, causing damage to the titanium alloy wire. Once the titanium alloy wire accumulates on the left side of the wire drawing die 121, the accumulated titanium alloy wire presses the rotating plate 51, the rotating plate 51 rotates, the rotating plate 51 loses contact with the limit block 53, and the second elastic member 52 is stretched, thereby driving the position sensor thereon to move. The usage state of the wire drawing die 121 is detected by the position sensor. When it is detected that the position sensor moves closer to the right side of the workbench 1, it indicates that the wire drawing die 121 is damaged. Then the staff replaces the wire drawing die 121 and cleans the accumulated titanium alloy wire. At the same time, the rotating plate 51 is pulled back by the adjacent second elastic member 52 and contacts the limit block 53. After use, the electrical components are turned off.

[0048] During the process of winding the titanium alloy wire, since the rotation speed of the winding roller remains unchanged, when there is more and more titanium alloy wire on the winding roller, the length of the titanium alloy wire wound in one rotation of the winding roller becomes longer, and the pulling force on the titanium alloy wire becomes larger. When the pulling force for winding the titanium alloy wire is too large, it is easy to break the titanium alloy wire, affecting the integrity of the titanium alloy wire.

[0049] Example 2: On the basis of Example 1, as Figure 1 and Figures 12-15As shown in the figure, it further includes a winding mechanism which is arranged on the right side of the workbench 1. The winding mechanism is used for winding the drawn titanium alloy wire. The winding mechanism includes a motor 6 which is fixedly connected to the right side of the workbench 1. The output shaft of the motor 6 is fixedly connected with a second rotating shaft 61. A first fixing ring 62 is slidably connected to the rear side of the second rotating shaft 61. The front side of the first fixing ring 62 is provided with circumferentially distributed teeth. The second rotating shaft 61 is slidably and rotatably connected with a second fixing ring 63. The rear side of the second fixing ring 63 is provided with circumferentially distributed teeth. The second fixing ring 63 and the first fixing ring 62 are in transmission cooperation through their teeth. A torsion spring 64 is arranged on the front side of the second fixing ring 63. The front side of the torsion spring 64 is fixedly connected with a rotating shell 65. The rotating shell 65 is threadedly connected with the second fixing ring 63. The rotating shell 65 is detachably connected with a winding roller 67. A third fixing ring 7 is fixedly connected to the rear side of the second rotating shaft 61. A third elastic member 71 is fixedly connected between the third fixing ring 7 and the first fixing ring 62. The third elastic member 71 is always in a state of storing energy. The third elastic member 71 is a spring. The first fixing ring 62 is rotatably connected with a rotating ring 72. The rotating ring 72 and the rotating shell 65 are in limit cooperation. The motor 6 is fixedly connected with a fifth fixing bracket 73. A laser rangefinder is arranged on the fifth fixing bracket 73. The laser rangefinder is used for measuring the distance from the rotating ring 72 to the fifth fixing bracket 73. The elastic coefficient of the third elastic member 71 is less than the elastic coefficient of the torsion spring 64.

[0050] During the process of winding the titanium alloy wire after drawing, first fix the titanium alloy wire on the winding roller 67, and then start the motor 6. The output shaft of the motor 6 drives the second rotating shaft 61 to rotate. The second rotating shaft 61 drives the first fixing ring 62 to rotate. The first fixing ring 62 drives the second fixing ring 63 to rotate through the teeth. While the second fixing ring 63 rotates, it drives the torsion spring 64 to rotate. The torsion spring 64 drives the rotating shell 65 to rotate. The rotating shell 65 drives the winding roller 67 to rotate. The winding roller 67 winds the titanium alloy wire. There is a pulling force when the titanium alloy wire is wound. During the rotation of the second fixing ring 63, the second fixing ring 63 moves forward under the drive of its thread. During the forward movement of the second fixing ring 63, the first fixing ring 62 gradually moves forward under the action of the third elastic member 71. The rotating ring 72 moves forward synchronously, and drives the winding roller 67 to rotate through the torsion spring 64 to wind the titanium alloy wire.

[0051] As more and more titanium alloy wires are wound on the winding roller 67, the constant rotational speed of the output shaft of the motor 6 will gradually tighten the titanium alloy wires, and the rotational speed of the winding roller 67 will slow down. The winding roller 67 rotates at the same speed as the rotating housing 65. At this time, a speed difference is formed between the rotating housing 65 and the second rotating shaft 61. The second rotating shaft 61 continues to drive the second fixing ring 63 to rotate, and the second fixing ring 63 moves forward. The second fixing ring 63 gradually disengages from the first fixing ring 62. After the second fixing ring 63 disengages, the whole formed by the second fixing ring 63, the torsion spring 64 and the rotating housing 65 is rotationally connected to the second rotating shaft 61. The motor 6 no longer drives the winding roller 67 to rotate through the transmission, and the titanium alloy wires are released. At the same time, the torsion spring 64 is released, and the torsion spring 64 drives the second fixing ring 63 and the rotating housing 65 to rotate relatively, so that the second fixing ring 63 moves backward under the action of the thread, and the second fixing ring 63 gradually comes into contact with the first fixing ring 62 again, reducing the probability of the titanium alloy wires breaking due to excessive tension.

[0052] When the titanium alloy wires break accidentally, the torsion spring 64 is released. The torsion spring 64 drives the second fixing ring 63 to rotate and moves backward under the limit of the thread. The second fixing ring 63 squeezes the first fixing ring 62 to move backward, and the rotating ring 72 moves synchronously. The third elastic member 71 is stretched. At this time, the distance between the rotating ring 72 and the fifth fixing bracket 73 is shortened. The signal at this time is transmitted outward through the laser rangefinder on the fifth fixing bracket 73, indicating that the titanium alloy wires break at this time. After the winding is completed, the motor 6 is turned off.

[0053] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. The narrative way of this specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
