Description

Technical Field

[0001] The invention relates to the technical field of titanium alloy wire processing, in particular to a titanium alloy wire drawing device. Background Art

[0002] Titanium alloy wire is a slender titanium alloy wire made of titanium alloy material through a drawing process. Titanium alloy wire has excellent properties such as high strength and corrosion resistance, and is widely used in various fields. In the process of drawing titanium alloy wire, the titanium alloy wire needs to pass through lubricating powder before passing through the drawing mold. 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 mold, reduce the direct contact between the titanium alloy wire and the mold, and thus reduce the energy consumption in the drawing process. In the existing production process, the titanium alloy wire is only passed through a box filled with lubricating powder, and the adhesion effect of the lubricating powder on the titanium alloy wire cannot be guaranteed. In addition, during use, the position of the titanium alloy wire in the lubricating powder is relatively stable, but the lubricating powder at the position of the titanium alloy wire is continuously consumed, and the lubricating powder does not circulate. If the lubricating powder agglomerates or becomes 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.

[0020] The titanium alloy wire needs to pass through lubricating powder before passing through the drawing mold.

In the existing production process, the titanium alloy wire is simply passed through a box filled with lubricating powder, which cannot guarantee the adhesion effect of the titanium alloy wire.

The drawing wheel 122 drives the alloy wire to move to the right through its own rotation, and a powder inlet shell 13 is fixedly connected between the mounting box 11 and the storage shell 12.

[0022] like Figure 3-Figure 5 As shown, the storage shell 12 is fixedly connected to a first fixing frame 18, and two limit columns 19 symmetrically distributed on the left and right are fixedly connected to the lower side of the first fixing frame 18. The two limit columns 19 symmetrically distributed on the left and right are both slidably connected to the sealing cover 17. The limit 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. Two symmetrically distributed springs 110 are fixedly connected between the sealing cover 17 and the first fixing frame 18, and the springs 110 are used to reset the sealing cover 17. The left side of the installation box 11 is fixedly connected and connected to a first sealing sleeve 111, and the first sealing sleeve 111 is a hollow cone made of rubber material.

[0023] like Figure 3 and Figure 6 As shown, the power assembly includes a second fixed frame 2, the second fixed frame 2 is fixedly connected to the left side of the installation box 11, the second fixed frame 2 is rotatably connected to a fixed roller 21, the left side of the installation box 11 is rotatably connected to a first rotating shaft 22, the fixed roller 21 and the first rotating shaft 22 are driven by a pulley belt, the first rotating shaft 22 and the rotating column 14 are driven by a bevel gear set, the rear side of the second fixed frame 2 is slidably connected to two sliding plates 24 symmetrically distributed up and down, a sliding roller 23 is rotatably connected between the two sliding plates 24 symmetrically distributed up and down, a first elastic member 25 is fixed between the sliding plate 24 and the second fixed frame 2, the first elastic member 25 is an elastic pull rope, which is used to drive the sliding plate 24 to move forward, and a pre-extrusion assembly is arranged in the installation box 11, and the pre-extrusion assembly is used to extrude titanium alloy wire.

[0024] like Figure 3 and Figure 7-Figure 9 As shown, the pre-extrusion assembly includes a fixed shell 3, which is fixedly connected to the installation box 11. The fixed shell 3 is located on the right side of the storage shell 12. The fixed shell 3 is cylindrical. Three groups of hydraulic telescopic rods 31 are arranged in the fixed shell 3. Each group of hydraulic telescopic rods 31 has two symmetrically distributed ones. The telescopic ends of the three groups of hydraulic telescopic rods 31 are all facing the inside of the fixed shell 3. The two adjacent groups of hydraulic telescopic rods 31 are staggered. The telescopic ends of the hydraulic telescopic rods 31 are fixedly connected to the third fixed frame 32. The third fixed frame 32 is rotatably connected to the extrusion wheel 33. The left side of the fixed shell 3 is fixedly connected and connected to the second sealing sleeve 34. The second sealing sleeve 34 is a hollow frustum of rubber material. The fixed shell 3 is fixedly connected to a connecting piece 35. The connecting piece 35 is connected by three annular tubes. The connecting piece 35 is connected to the three groups of hydraulic telescopic rods 31. The connecting piece 35 is fixedly connected and connected to a conduit 36. The conduit 36 ​​is connected to an external hydraulic system for providing hydraulic oil to the hydraulic telescopic rod 31 and controlling the telescopic end of the hydraulic telescopic rod 31 to retract.

[0025] like Figure 8 and Fig. 9 As shown, the hydraulic telescopic rod 31 on the upper side of the rightmost group of hydraulic telescopic rods 31 is sealed and slidably connected with a first limit member 4, and the first limit 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 limit member 4 moves synchronously, and the fixed shell 3 is fixedly connected to the limit plate 41. The limit plate 41 is provided with a pressure sensor, and the pressure sensor is electrically connected to the external hydraulic system. The first limit member 4 is squeezed and matched with the pressure sensor on the limit plate 41. When the telescopic end of the hydraulic telescopic rod 31 on the upper right side moves downward, the first limit member The pressure sensor on the extrusion limit plate 41 transmits an electrical signal to the hydraulic system to control the hydraulic system to be closed. The hydraulic telescopic rod 31 on the lower right side is sealed and slidably connected with a second limiter 42. The second limiter 42 is fixedly connected to the telescopic portion of the adjacent hydraulic telescopic rod 31. The second limiter 42 is limitedly matched with the adjacent hydraulic telescopic rod 31. When in use, the second limiter 42 limits the movement of the hydraulic telescopic rod 31. A detection mechanism is provided on one side of the installation box 11 close to the wire drawing die 121. The detection mechanism is used to detect the state of the wire drawing die 121.

[0026] like Fig.10 and Fig.11As shown, the detection mechanism includes two fixed plates 5 symmetrically distributed up and down, the two fixed plates 5 symmetrically distributed up and down are both fixed to the right side of the installation box 11, the fixed plate 5 is rotatably connected with a rotating plate 51, a second elastic member 52 is fixed between the fixed plate 5 and the installation box 11, the second elastic member 52 is an elastic pull rope, the installation box 11 is fixed with a limit block 53 that contacts and cooperates with the two symmetrically distributed rotating plates 51, notches are opened between the symmetrically distributed rotating plates 51, a position sensor is arranged on the rotating plate 51, the position sensor is used to detect the distance between itself and the installation box 11, a symmetrically distributed fourth fixed frame 54 is fixed to the side of the installation box 11 away from the second fixed frame 2, and the fourth fixed frame 54 is rotatably connected with a limiting roller 55.

[0027] In the process of using the present device to draw the titanium alloy wire, the titanium alloy wire is first passed 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 the titanium alloy wire is wound onto the drawing wheel 122, and the titanium alloy wire is pulled by rotating the drawing wheel 122 to pass through the wire drawing die 121. The titanium alloy wire is extruded by the wire drawing die 121 to make the titanium alloy wire thinner.

[0028] In the process of the titanium alloy wire passing through the fixed roller 21 and the sliding roller 23, the titanium alloy wire squeezes the sliding roller 23 and moves backward. In the process of moving backward, the sliding roller 23 drives the upper and lower sliding plates 24 to slide backward. The sliding plate 24 pulls the first elastic member 25 to extend, and squeezes the titanium alloy wire through the sliding roller 23, so that the titanium alloy wire fits with the fixed roller 21 and the sliding roller 23. In the process of the titanium alloy wire moving to the right, the titanium alloy wire drives the fixed roller 21 to rotate clockwise (looking from top to bottom), and the fixed roller 21 drives the first elastic member 25 to extend. The rotating shaft 22 rotates, and the first rotating shaft 22 drives the rotating column 14 to rotate clockwise (viewed from left to right) through the bevel gear set, and 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, and the lubricating powder enters the storage shell 12 through the fixed tube 16, squeezing the lubricating powder in the storage shell 12, so that the titanium alloy wire is fully in contact with the lubricating powder, and the lubricating powder in the storage shell 12 is kept at a certain pressure.

[0029] During the rotation of the rotating column 14, the lubricating powder on the powder inlet shell 13 gradually enters the storage shell 12, and the vibration module on the storage shell 12 is started to make the lubricating powder vibrate. During the movement, the amount of lubricating powder adhered to the titanium alloy wire is less than the amount of lubricating powder entering the storage shell 12. The lubricating powder in the storage shell 12 squeezes the sealing cover 17. When the pressure of the lubricating powder can overcome the two springs 110, the lubricating powder squeezes the sealing cover 17 to move upward, and the sealing cover 17 squeezes 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, so that the lubricating powder in the storage shell 12 and the powder inlet shell 13 continues to circulate, thereby improving the fluidity of the lubricating powder and preventing part of the lubricating powder from agglomerating under long-term extrusion. When the lubricating powder in the powder inlet shell 13 is reduced, the staff replenishes the lubricating powder in the powder inlet shell 13.

[0030] When the titanium alloy wire just starts to move to the right, the staff starts the external hydraulic system, and the hydraulic system introduces hydraulic oil into the conduit 36. The hydraulic oil enters three groups of six hydraulic telescopic rods 31 through the connecting piece 35. The telescopic end of the hydraulic telescopic rod 31 drives the adjacent third fixed frame 32 to move toward the middle of the fixed shell 3, and the third fixed frame 32 drives the extrusion wheel 33 to extrude the titanium alloy wire. In the process of introducing hydraulic oil, the six extrusion wheels 33 synchronously extrude the titanium alloy wire, and the telescopic ends of the two hydraulic telescopic rods 31 on the right side continue to move. In the process of the telescopic end of the upper right hydraulic telescopic rod 31 moving downward, it drives the limit plate 41 to move downward. In the process of the telescopic end of the lower right hydraulic telescopic rod 31 moving downward, it drives the second limit member 42 to move upward. In the process of the second limit member 42 moving upward, The second limit piece 42 gradually contacts the bottom end of the lower right hydraulic telescopic rod 31, and the second limit piece 42 no longer moves, thereby causing the telescopic end of the lower right hydraulic telescopic rod 31 to no longer move. The first limit piece 4 gradually contacts the limit plate 41 during the downward movement, squeezing the pressure sensor on the limit plate 41. The pressure sensor transmits a signal to the hydraulic system to stop delivering hydraulic oil to the conduit 36. At this time, the second limit piece 42 contacts the bottom end of the lower right hydraulic telescopic rod 31, and the two extrusion wheels 33 on the right squeeze the titanium alloy wire to a set width. The titanium alloy wire is thinned by the gradual extrusion of the three groups of extrusion wheels 33. The pressure of the three groups of extrusion wheels 33 is the same, and the titanium alloy wire is evenly extruded, so that the titanium alloy wire is evenly stressed to prevent the titanium alloy wire from being damaged. The final width of the titanium alloy wire is controlled by the first limit piece 4.

[0031] During the process of extruding the titanium alloy wire by the extrusion wheel 33, the extrusion wheel 33 makes the lubricating powder and the titanium alloy wire fit tightly together, and then the titanium alloy wire passes through the two rotating plates 51, and finally passes through the wire drawing die 121. The titanium alloy wire that meets the specifications is obtained by 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. The lubricating powder and the titanium alloy wire are fit together during the extrusion process, which improves the lubrication effect of the titanium alloy wire, thereby improving the drawing quality of the titanium alloy wire.

[0032] During the drawing process using the wire drawing die 121, if the wire drawing die 121 is damaged and has a gap, 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, peel off part of the skin of the titanium alloy wire from the titanium alloy wire, and accumulate 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 squeezes 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 use status of the wire drawing die 121 is detected by the position sensor. When the position sensor is detected to be close 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 component is turned off.

[0033] In the process of winding the titanium alloy wire, since the rotation speed of the winding roller remains unchanged, when more and more titanium alloy wires are on the winding roller, the wound titanium alloy wire becomes longer when the winding roller rotates one circle, and the tension on the titanium alloy wire becomes greater. When the tension of the wound titanium alloy wire is too great, the titanium alloy wire is easily broken, affecting the integrity of the titanium alloy wire.

[0034] Embodiment 2: Based on embodiment 1, Figure 1 and Figure 12-Figure 15As shown, it also includes a winding mechanism, which is arranged on the right side of the workbench 1. The winding mechanism is used to wind up the titanium alloy wire that has been drawn. 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 to a second rotating shaft 61. The rear side of the second rotating shaft 61 is slidably connected to a first fixed ring 62. The front side of the first fixed ring 62 is provided with circumferentially distributed teeth. The second rotating shaft 61 is slidably and rotatably connected to a second fixed ring 63. The rear side of the second fixed ring 63 is provided with circumferentially distributed teeth. The second fixed ring 63 and the first fixed ring 62 are matched through their teeth transmission. The front side of the second fixed ring 63 is a torsion spring 64, and the front side of the torsion spring 64 is fixed A rotating shell 65 is connected, and the rotating shell 65 is connected to the second fixed ring 63 by threads. The rotating shell 65 is detachably connected to the winding roller 67. A third fixed 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 fixed ring 7 and the first fixed ring 62. The third elastic member 71 always stores force. The third elastic member 71 is a spring. The first fixed ring 62 is rotatably connected to a rotating ring 72. The rotating ring 72 is limitedly matched with the rotating shell 65. The motor 6 is fixedly connected to a fifth fixed frame 73. A laser rangefinder is provided on the fifth fixed frame 73. The laser rangefinder is used to measure the distance from the rotating ring 72 to the fifth fixed frame 73. The elastic coefficient of the third elastic member 71 is smaller than the elastic coefficient of the torsion spring 64.

[0035] During the process of winding the titanium alloy wire after drawing, the titanium alloy wire is first fixed on the winding roller 67, and then the motor 6 is started. The output shaft of the motor 6 drives the second rotating shaft 61 to rotate, and the second rotating shaft 61 drives the first fixed ring 62 to rotate. The first fixed ring 62 drives the second fixed ring 63 to rotate through the teeth. The second fixed ring 63 drives the torsion spring 64 to rotate while rotating. 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 tension when the titanium alloy wire is wound. During the rotation of the second fixed ring 63, the second fixed ring 63 moves forward driven by the thread thereon. During the forward movement of the second fixed ring 63, the first fixed ring 62 gradually moves forward under the action of the third elastic member 71, and the rotating ring 72 moves forward synchronously. The winding roller 67 is driven to rotate by the torsion spring 64 to wind the titanium alloy wire.

[0036] As more and more titanium alloy wire is on the winding roller 67, the constant speed of the output shaft of the motor 6 will gradually tighten the titanium alloy wire, the rotation speed of the winding roller 67 slows down, and the winding roller 67 rotates at the same speed as the rotating shell 65. At this time, a speed difference is formed between the rotating shell 65 and the second rotating shaft 61, and the second rotating shaft 61 continues to drive the second fixed ring 63 to rotate, and the second fixed ring 63 moves forward, and the second fixed ring 63 gradually disengages from the first fixed ring 62. After the second fixed ring 63 disengages, the second fixed ring 63, the torsion spring 64 and the rotating shell 65 are formed as a whole and are rotationally connected to the second rotating shaft 61, and the motor 6 no longer drives the winding roller 67 to rotate through transmission, and the titanium alloy wire is released. At the same time, the torsion spring 64 is released, and the torsion spring 64 drives the second fixed ring 63 and the rotating shell 65 to rotate relative to each other, so that the second fixed ring 63 moves backward under the action of the thread, and the second fixed ring 63 gradually re-contacts with the first fixed ring 62, reducing the probability of the titanium alloy wire breaking due to excessive tension.

[0037] When the titanium alloy wire breaks accidentally, the torsion spring 64 is released, and the torsion spring 64 drives the second fixed ring 63 to rotate and move backward under the limit of the thread, the second fixed ring 63 squeezes the first fixed ring 62 to move backward, the rotating ring 72 moves synchronously, and the third elastic member 71 is stretched. At this time, the distance between the rotating ring 72 and the fifth fixed frame 73 is shortened, and the signal at this time is transmitted to the outside through the laser rangefinder on the fifth fixed frame 73, indicating that the titanium alloy wire is broken at this time. After the winding is completed, the motor 6 is turned off.

[0038] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
