Description

Technical Field

[0001] This invention relates to the field of wire drawing machine technology, and in particular to a highly stable drawing device based on nickel-titanium wire production and processing. Background Technology

[0002] Nickel-titanium wire typically requires diameter reduction during production using a drawing device. A drum-type drawing device can continuously pull the nickel-titanium wire through a drum traction wheel, allowing the wire to achieve the target diameter after passing through the drawing die.

[0003] Existing drawing devices mostly use lubricating fluid tanks, spray pipes, or ordinary immersion methods to lubricate the drawing area. The stability of the lubricating fluid entering the drawing die entrance area is insufficient. Especially when the nickel-titanium wire is in a high-tension continuous drawing state, problems such as insufficient lubricating fluid renewal, lubricating fluid retention due to heat, and abrasive debris accumulation with the liquid are prone to occur at the die entrance, which in turn affect the surface quality and drawing stability of the nickel-titanium wire.

[0004] Therefore, it is necessary to invent a highly stable drawing device based on nickel-titanium wire production and processing to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a highly stable drawing device based on nickel-titanium wire production and processing, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a highly stable drawing device based on nickel-titanium wire production and processing, comprising a drum traction wheel, a lubricating fluid tank, an inlet guide roller group, a die base mounting plate, and a drawing die head. The lubricating fluid tank is located on the inlet side of the drum traction wheel, the die base mounting plate is fixed to the outlet end of the lubricating fluid tank, the drawing die head is fixed to the die base mounting plate, and a fluid supply assembly is installed in the lubricating fluid tank and located between the inlet guide roller group and the drawing die head. The liquid supply assembly includes a support base, a swirling sleeve, two liquid supply covers, a spiral guide vane, a liquid guide plate, a liquid outlet nozzle, and an arc-shaped baffle. The support base is fixed inside the lubricating fluid tank. The swirling sleeve is rotatably mounted on the support base and coaxial with the drawing die. The two liquid supply covers are located outside the swirling sleeve and form a liquid supply cavity with the swirling sleeve. The swirling sleeve has an axial liquid passage groove connecting the liquid supply cavity and the inside of the swirling sleeve. The spiral guide vane is fixed inside the swirling sleeve and guides the liquid away from the drawing die. The liquid guide plate is fixed at one end of the swirling sleeve near the drawing die. The liquid outlet nozzle is mounted on the liquid guide plate and faces the drawing die.

[0008] Preferably, it also includes an inlet guide, which is installed at the end of the lubricant tank away from the drum traction wheel; It also includes a cable outlet, which is located at one end of the lubricant tank near the drum traction wheel; and a die head support, which is fixed to the cable outlet and abuts against the drawing die head.

[0009] Preferably, the system further includes a bearing, which is installed inside the support base, the swirling sleeve passes through the inner ring of the bearing, and the outer ring of the bearing is fixed to the support base.

[0010] Preferably, the liquid supply assembly further includes an inlet end limiting sleeve, which is sleeved on the end of the swirl sleeve away from the drawing die. The liquid supply assembly further includes an inlet locking member, which is sleeved on the inlet limiting sleeve; the liquid supply assembly also includes two end rotating support seats, one end rotating support seat is sleeved on one end of the vortex sleeve, and the other end rotating support seat is sleeved on one end of the inlet locking member, the vortex sleeve and the inlet locking member respectively rotate relative to the corresponding end rotating support seat.

[0011] Preferably, the end rotating support seat is recessed on one side facing the liquid supply cover to form a limiting groove, the two liquid supply covers are radially aligned with the swirl sleeve, and the axial end of the liquid supply cover extends into the limiting groove.

[0012] Preferably, the axial liquid passage extends along the axial direction of the swirl sleeve, and the spiral guide vane extends spirally along the inner wall of the swirl sleeve. The spiral direction of the spiral guide vane matches the rotation direction of the swirl sleeve and guides the flow away from the drawing die.

[0013] Preferably, the liquid guide plate has an annular liquid guide cavity, and the end face of the liquid guide plate near the drawing die head has a nozzle mounting groove. The liquid outlet nozzle is fixed to the nozzle mounting groove and communicates with the annular liquid guide cavity.

[0014] Preferably, it further includes an annular sealing plate, which is installed on the liquid guide plate and rotates relative to the liquid guide plate; It also includes a fixed liquid supply pipe, which is fixed to the annular sealing plate and communicates with the annular liquid guiding cavity. The angle between the spray axis of the liquid outlet nozzle and the die hole axis of the drawing die is 10° to 45°, and the projection of the spray axis in the direction of the die hole axis points to the drawing die.

[0015] Preferably, it also includes a driven gear ring, which is fixedly sleeved on the outer side of one end of the swirling sleeve near the liquid guide plate; It also includes a driving gear, which meshes with the driven gear ring; It also includes a drive motor, which is fixed to the mold base mounting plate, and the drive gear is fixedly sleeved on the output end of the drive motor.

[0016] The technical effects and advantages of this invention are as follows: 1. This invention provides a liquid supply assembly between the infeed guide roller group and the drawing die, so that the swirling sleeve, the liquid supply cover, the axial liquid passage groove and the spiral guide vane together form a full liquid coverage and reverse flow structure. When the nickel-titanium wire passes through the swirling sleeve, it can be continuously covered by the lubricating liquid. At the same time, the heated lubricating liquid near the entrance of the drawing die can be carried away in a direction away from the drawing die, thereby reducing the retention of hot liquid and abrasive debris at the die entrance and improving the lubrication stability during the continuous drawing process of nickel-titanium wire. 2. The present invention provides a liquid guide plate, a liquid outlet nozzle and an arc-shaped baffle at one end of the swirl sleeve near the drawing die head, so that the liquid outlet nozzle replenishes the lubricating fluid to the inlet area of ​​the drawing die head, and the arc-shaped baffle constrains and guides the sprayed lubricating fluid, thereby forming a continuously renewed lubricating fluid area near the inlet of the drawing die head, and further reducing the possibility of local dry friction and surface scratches when the nickel-titanium wire enters the die hole; 3. By setting up an annular sealing plate, a fixed liquid supply pipe, an end rotating support, a bearing, a driven gear ring, a driving gear, and a drive motor, the present invention enables the swirling sleeve and the liquid guide plate to rotate under drive, while the liquid supply pipe, the liquid supply cover, and the end rotating support can remain relatively stable, avoiding the liquid supply pipe from getting tangled with the rotating parts, and ensuring that there is no hard interference between the rotating liquid supply, the end face spraying, and the drum traction action.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] In this embodiment, the direction in which the nickel-titanium wire moves from the infeed guide roller group 3 to the drum traction wheel 11 is taken as the direction of travel of the nickel-titanium wire. The side closer to the infeed guide roller group 3 is the infeed side, and the side closer to the drum traction wheel 11 is the outfeed side.

[0031] like Figures 1 to 11 As shown, a high-stability drawing device based on nickel-titanium wire production and processing according to the present invention includes a drum traction wheel 11, a lubricating fluid tank 2, an inlet guide roller group 3, a die holder mounting plate 4, a drawing die head 41, and a fluid supply assembly 5. The drum traction wheel 11 is rotatably mounted on the drawing machine housing 1. The lubricating fluid tank 2 is located on the inlet side of the drum traction wheel 11. The inlet guide roller group 3 is disposed at the inlet end of the lubricating fluid tank 2. The die holder mounting plate 4 is fixed at the outlet end of the lubricating fluid tank 2. The drawing die head 41 is fixed on the die holder mounting plate 4. The fluid supply assembly 5 is installed in the lubricating fluid tank 2 and located between the inlet guide roller group 3 and the drawing die head 41.

[0032] A wire inlet guide 21 is installed at the end of the lubricating fluid tank 2 away from the drum traction wheel 11. A wire outlet 22 is opened at the end of the lubricating fluid tank 2 near the drum traction wheel 11. A die head support 221 is fixed at the wire outlet 22. The die head support 221 abuts against the side of the drawing die head 41 away from the liquid supply component 5, so that in addition to being fixed by the die base mounting plate 4, the drawing die head 41 can also be supported by the die head support 221 on the wire outlet side.

[0033] The liquid supply assembly 5 includes a support base 502, a swirling sleeve 51, two liquid supply covers 53, a spiral guide vane 512, a liquid guide plate 54, a liquid outlet nozzle 542, and an arc-shaped baffle 546. The support base 502 is fixed in the lubricating liquid tank 2. A bearing 501 is installed in the support base 502. The outer ring of the bearing 501 is fixed on the support base 502. The swirling sleeve 51 passes through the inner ring of the bearing 501, so that the swirling sleeve 51 can rotate relative to the support base 502. The swirling sleeve 51 is coaxially arranged with the die hole of the drawing die head 41.

[0034] Two liquid supply covers 53 are installed on the outside of the vortex sleeve 51. A liquid supply cavity is formed between the inner wall of the liquid supply cover 53 and the outer wall of the vortex sleeve 51. A rotation gap is maintained between the liquid supply cover 53 and the vortex sleeve 51 so that the liquid supply cover 53 does not generate hard friction with the vortex sleeve 51 when it is relatively stationary. The liquid supply cavity is continuously injected with lubricating fluid through the external liquid supply structure. The vortex sleeve 51 is provided with an axial liquid passage groove 511. The axial liquid passage groove 511 connects the liquid supply cavity and the inside of the vortex sleeve 51, so that the lubricating fluid can enter the inside of the vortex sleeve 51 and keep the nickel-titanium wire in a lubricating fluid-coated state.

[0035] A spiral guide vane 512 is fixed inside the swirl sleeve 51. The spiral guide vane 512 extends spirally along the inner wall of the swirl sleeve 51. The spiral direction of the spiral guide vane 512 matches the rotation direction of the swirl sleeve 51, and causes the lubricating fluid inside the swirl sleeve 51 to flow away from the drawing die head 41, thereby carrying away the heated lubricating fluid and the lubricating fluid carrying abrasive debris near the inlet of the drawing die head 41 towards the wire inlet side.

[0036] The end of the swirling sleeve 51 away from the drawing die head 41 is fitted with an inlet end limiting sleeve 52, and an inlet end locking member 521 is fitted on the inlet end limiting sleeve 52. The liquid supply assembly 5 also includes two end rotating support seats 531. One end rotating support seat 531 is fitted on one end of the swirling sleeve 51, and the other end rotating support seat 531 is fitted on one end of the inlet end locking member 521. The swirling sleeve 51 and the inlet end locking member 521 are respectively rotated relative to the corresponding end rotating support seat 531.

[0037] The end rotating support 531 is recessed on the side facing the liquid supply cover 53 to form a limiting groove. The two liquid supply covers 53 are radially aligned along the swirl sleeve 51. The axial end of the liquid supply cover 53 extends into the limiting groove. The end rotating support 531 is used to axially limit the liquid supply cover 53 so that the liquid supply cover 53 can be kept outside the swirl sleeve 51 to form a liquid supply cavity, and does not rotate synchronously with the swirl sleeve 51.

[0038] The liquid guide plate 54 is fixed at one end of the swirl sleeve 51 near the drawing die head 41. The liquid guide plate 54 rotates synchronously with the swirl sleeve 51. An annular liquid guide cavity 543 is provided inside the liquid guide plate 54. A nozzle mounting groove 541 is provided on the end face of the liquid guide plate 54 near the drawing die head 41. The liquid outlet nozzle 542 is fixed in the nozzle mounting groove 541 and communicates with the annular liquid guide cavity 543. The liquid outlet end of the liquid outlet nozzle 542 faces the inlet peripheral area of ​​the drawing die head 41.

[0039] An annular sealing plate 544 is installed on the liquid guide plate 54. The annular sealing plate 544 rotates relative to the liquid guide plate 54. The fixed liquid supply pipe 545 is fixed on the annular sealing plate 544 and communicates with the annular liquid guide cavity 543. The fixed liquid supply pipe 545 can be connected to an external high-pressure liquid supply line. The external high-pressure liquid supply line continuously supplies lubricating fluid to the annular liquid guide cavity 543, so that the lubricating fluid is sprayed at high speed through the liquid outlet nozzle 542 to the inlet area of ​​the drawing die head 41.

[0040] The spray axis of the liquid outlet nozzle 542 forms an angle of 10° to 45° with the die hole axis of the drawing die head 41. The projection of the spray axis in the direction of the die hole axis points towards the drawing die head 41, so that the lubricant sprayed by the liquid outlet nozzle 542 is directed towards the inlet of the drawing die head 41, while avoiding the liquid outlet nozzle 542 directly impacting the center of the nickel-titanium wire.

[0041] The arc-shaped baffle 546 is fixed on the side of the liquid guide plate 54 near the drawing die 41. The arc-shaped baffle 546 extends into the inlet area of ​​the drawing die 41. The arc-shaped baffle 546 maintains a clearance fit with the inner wall of the inlet of the drawing die 41 and the nickel-titanium wire, so that the arc-shaped baffle 546 will not interfere with the drawing die 41 or the nickel-titanium wire when it rotates with the liquid guide plate 54. At the same time, it can constrain the lubricating liquid sprayed from the liquid outlet nozzle 542, so that the lubricating liquid is concentrated in the inlet area of ​​the drawing die 41.

[0042] A driven gear ring 55 is fixedly sleeved on the outer side of one end of the swirling sleeve 51 near the liquid guide plate 54. The driving gear 551 meshes with the driven gear ring 55. The drive motor 552 is fixed on the mold base mounting plate 4. The driving gear 551 is fixedly sleeved on the output end of the drive motor 552. When the drive motor 552 is working, it drives the driving gear 551 to rotate. The driving gear 551 drives the swirling sleeve 51 and the liquid guide plate 54 to rotate through the driven gear ring 55.

[0043] After the drive motor 552 starts, the output end of the drive motor 552 drives the drive gear 551 to rotate. The drive gear 551 drives the swirling sleeve 51 to rotate by meshing with the driven gear ring 55. Since the liquid guide plate 54 is fixed at one end of the swirling sleeve 51 near the drawing die head 41, the liquid guide plate 54 rotates synchronously with the swirling sleeve 51, while the liquid supply cover 53, the end rotating support seat 531, the annular sealing plate 544 and the fixed liquid supply pipe 545 remain relatively stationary, thus forming a separate assembly relationship between the rotating guide component and the fixed liquid supply component.

[0044] After the lubricant enters the supply cavity formed by the two supply shrouds 53 and the swirl sleeve 51, it enters the swirl sleeve 51 through the axial liquid channel 511. The liquid inside the swirl sleeve 51 surrounds the nickel-titanium wire to form a fully liquid-covered state, so that the nickel-titanium wire passes through a coaxial liquid-covered area before entering the drawing die 41, thus avoiding the nickel-titanium wire from entering the drawing die 41 inlet directly in a liquid-deficient state.

[0045] When the swirl sleeve 51 rotates, the spiral guide vane 512 fixed on the inner wall of the swirl sleeve 51 rotates synchronously with the swirl sleeve 51. The spiral direction of the spiral guide vane 512 causes the lubricant inside the swirl sleeve 51 near the drawing die 41 to move away from the drawing die 41, thereby carrying away the heated lubricant and the lubricant carrying the wear debris near the inlet of the drawing die 41 towards the wire inlet side.

[0046] Lubricating fluid is supplied into the annular liquid guiding cavity 543 through the fixed liquid supply pipe 545. After being distributed through the annular liquid guiding cavity 543, the lubricating fluid enters the liquid outlet nozzle 542. The liquid outlet nozzle 542 sprays the lubricating fluid in the direction of the peripheral area of ​​the inlet of the drawing die head 41. The arc-shaped baffle 546 locally constrains the sprayed lubricating fluid, so that the newly added lubricating fluid is concentrated on the inlet area of ​​the drawing die head 41. The reverse liquid carrying effect of the spiral guide plate 512 forms a circulating liquid supply state of new liquid replenishment and old liquid removal.

[0047] A rotational clearance is maintained between the liquid supply hood 53 and the swirling sleeve 51, and a clearance is maintained between the arc-shaped baffle 546 and the inner wall of the drawing die 41 inlet and the nickel-titanium wire. When the swirling sleeve 51, the liquid guide plate 54, and the arc-shaped baffle 546 rotate, they do not make hard contact with the liquid supply hood 53, the drawing die 41, and the nickel-titanium wire, thereby avoiding mechanical interference to the drawing path of the nickel-titanium wire during the rotation of the liquid supply assembly 5.

[0048] During operation, the nickel-titanium wire sequentially passes through the inlet guide 21, the inlet guide roller group 3, the swirl sleeve 51, the drawing die 41, and the outlet 22 before entering the winding drum traction wheel 11. An external liquid supply structure supplies lubricating fluid to the liquid supply cavity between the liquid supply cover 53 and the swirl sleeve 51. The lubricating fluid enters the swirl sleeve 51 through the axial liquid channel 511, ensuring the nickel-titanium wire is fully coated with lubricating fluid before entering the drawing die 41. As the swirl sleeve 51 rotates, the spiral... The guide vane 512 carries the lubricant inside the swirl sleeve 51 away from the drawing die 41 and away from the drawing die 41. The fixed supply pipe 545 supplies the lubricant to the annular liquid guiding cavity 543 in the liquid guiding plate 54. The liquid outlet nozzle 542 sprays the lubricant at high speed into the inlet area of ​​the drawing die 41. The arc-shaped baffle 546 confines the sprayed lubricant near the inlet, so that a circulating lubrication state is formed at the inlet of the drawing die 41 where new liquid is added and old liquid is carried away.

[0049] In summary, the present invention forms a full liquid coverage and reverse liquid carrying structure through the liquid supply cover 53, the swirling sleeve 51, the axial liquid passage groove 511 and the spiral guide plate 512; forms an end face liquid replenishment and inlet constraint structure through the liquid guide plate 54, the annular liquid guide cavity 543, the liquid outlet nozzle 542, the fixed liquid supply pipe 545 and the arc-shaped baffle 546; and coordinates the motion relationship between the rotating part and the fixed liquid supply part through the bearing 501, the end rotating support seat 531, the annular sealing plate 544, the driven gear ring 55, the driving gear 551 and the drive motor 552, thereby improving the lubrication stability of the nickel-titanium wire before entering the single drawing die 41 without adding a second drawing die 41.
