Description

Technical Field

[0001] The present application relates to the field of wire processing, and in particular to a device for straightening fine steel wires made of aviation high-temperature alloy materials. Background Art

[0002] In the field of aerospace, the choice of materials is crucial. Among them, high-temperature alloy materials, with their excellent high-temperature strength and corrosion resistance, have become important materials in the industry. In aircraft engines, brush seals are a newly developed new sealing technology. Compared with the traditional comb tooth structure, they are more adaptable to the vibration and expansion of the rotor and have the advantage of low leakage level. The brush seal consists of a front plate, a back plate and fine steel wires. During processing, the fine steel wires are cut into a certain length, and then the fine steel wires are placed in an array between the back plate and the front plate at a fixed angle. It is required that the fine steel wires cannot be staggered and the fine steel wires have no bends. Since the fine steel wires are in the form of coils, they need to be straightened.

[0003] In the prior art, a traction mechanism is used to pass the thin steel wire through a straightening machine to straighten the thin steel wire. The straightening machine squeezes the thin steel wire through two rows of staggered straightening rollers to change its straightness, thereby straightening it. Since the thin steel wire made of high-temperature alloy is relatively thin, the thin steel wire may fall off the straightening roller during the traction process. Moreover, the thin steel wire contacts the straightening roller and can only be straightened in the rolling direction of the straightening roller, and its straightening area is relatively low, which makes the straightening effect of the thin steel wire poor. After cutting is completed, the staff needs to repeat the straightening, resulting in low straightening efficiency. Summary of the invention

[0042] The staff places the thin steel wire coil on the coil rack 11, and then passes the thin steel wire wound on the coil through multiple positioning tubes 41 in turn and moves the thin steel wire along the axis of the positioning tube 41 through the traction mechanism 6, and the coil naturally rotates on the coil rack 11 with the traction of the traction mechanism 6; the two adjacent V-shaped limit plates 43 at the end of each positioning tube 41 cross each other, and the thin steel wire is inserted between the corresponding V-shaped limit plates 43 in turn, so as to limit the thin steel wire and prevent it from falling off during the straightening process of the thin steel wire; at this time, under the action of the traction mechanism 6, the thin steel wire is in a taut state; with the rotation of the positioning tube 41, the two moving bars 42 arranged at the end of the positioning tube 41 can, under the action of the adjustment mechanism 5, synchronously approach or move away along the corresponding first rectangular groove 411, so that the two adjacent ones Each V-shaped limit plate 43 can contact the thin steel wire while rotating with the corresponding positioning tube 41, so that during the movement of the thin steel wire, force is applied to the thin steel wire within the entire circumference, thereby increasing the straightening range of the thin steel wire and ensuring the straightening effect of the thin steel wire; and, when two adjacent V-shaped limit plates 43 contact the thin steel wire, they can play a certain limiting role on the thin steel wire, increase the tension of the thin steel wire in a very short time, and enable the thin steel wire to be better corrected; after the contact is completed, the two adjacent V-shaped limit plates 43 can be separated from each other, so as to facilitate the traction mechanism 6 to continue to pull the thin steel wire and avoid the thin steel wire from breaking; secondly, the V-shaped limit plate 43 is preferably made of nylon material, so that it has excellent mechanical strength, wear resistance and good corrosion resistance, so as to effectively increase the service life of the V-shaped limit plate 43.

[0043] See also Figures 5 to 11 As shown, the straightening mechanism 4 also includes a synchronous cylinder 44 and a tapered ring 45; a positioning hole 441 for the positioning tube 41 to pass through is arranged at the center of the inner wall at the bottom of the synchronous cylinder 44, and the positioning tube 41 is slidably arranged in the corresponding positioning hole 441. The synchronous cylinder 44 is rotatably arranged inside the corresponding mounting tube 3, and a plurality of tightening cylinders 442 are arranged on the inner wall of the synchronous cylinder 44 along the axial direction, and the open end of each tightening cylinder 442 faces the axis of the synchronous cylinder 44 and is provided with a limiting ring 4421; a sliding disk 443 is slidably arranged inside each tightening cylinder 442, and a center of each sliding disk 443 is provided with a position ring facing the synchronous cylinder 4 4 connecting rods 4431 extending along the axis, the connecting rods 4431 are slidably arranged inside the corresponding limiting rings 4421, and each connecting rod 4431 is also sleeved with a separation spring 4433, and the separation spring 4433 is located between the limiting ring 4421 and the sliding disk 443; the conical ring 45 is fixedly arranged outside the positioning tube 41 and inside the synchronous cylinder 44, and a weighted ball 4432 for pushing the conical ring 45 to move is arranged at one end of each connecting rod 4431 away from the sliding disk 443; the conical ring 45 and the inner wall of the bottom of the synchronous cylinder 44 are connected to each other through a plurality of first elastic telescopic rods 451;

[0044] The U-shaped mounting frame 2 is provided with a driving mechanism 7 for driving a plurality of synchronous cylinders 44 to rotate.

[0045] In order to ensure that the thin steel wire remains taut during the straightening process, thereby ensuring the straightening effect; the multiple synchronous cylinders 44 are rotated in sequence by the driving mechanism 7, so that the V-shaped limit plates 43 arranged in the positioning tube 41 can straighten the thin steel wire in sequence; when the counterweight ball 4432 moves to the top of the positioning tube 41, due to gravity, the counterweight ball 4432 can overcome the elastic force of the separation spring 4433 and contact the conical ring 45, so that the conical ring 45 overcomes the elastic force of the first elastic telescopic rod 451 and slides along the positioning hole 441 synchronously with the positioning tube 41, so that the thin steel wire between every two positioning tubes 41 can receive corresponding tension, so that the thin steel wire can be subjected to a certain tension at different positions to keep it taut. As the synchronous cylinder 44 rotates, when the counterweight ball 4432 moves to the side of the positioning tube 41, under the elastic force of the separation spring 4433, The counterweight ball 4432 can be quickly reset. At this time, the conical ring 45 can also be quickly reset under the elastic force of the first elastic telescopic rod 451, so that tension can be intermittently applied to the thin steel wire segments, which not only makes it easier to pull out the thin steel wire on the coil, but also can further ensure the straightening effect of the V-shaped limit plate 43 on the thin steel wire.

[0046] See also Figures 2 to 6 As shown, the driving mechanism 7 includes a differential gear set 71, a rotating shaft 72 and a driving motor 73; a plurality of strip-shaped notches 21 for accommodating the differential gear set 71 are equidistantly arranged on the U-shaped mounting frame 2, and there are a plurality of differential gear sets 71, and the differential gear set 71 is rotatably arranged in the strip-shaped notch 21, and an arc-shaped notch 31 for avoiding the differential gear set 71 is arranged at one end of each mounting tube 3 close to the strip-shaped notch 21, and each synchronous cylinder 44 has a plurality of tooth grooves 444 arranged on the outer wall along the axial direction, and the differential gear set 71 meshes with the corresponding tooth grooves 444, and the rotating shaft 72 is rotatably arranged inside the U-shaped mounting frame 2, and a plurality of rotating gears 721 meshing with the differential gear set 71 are arranged on the rotating shaft 72 along the length direction, and the rotating gears 721 are located in the corresponding strip-shaped notches 21, and the driving motor 73 is arranged at one end of the U-shaped mounting frame 2 and is used to drive the rotating shaft 72 to rotate.

[0047] The rotating shaft 72 is driven to rotate by the driving motor 73, and the rotating shaft 72 drives the multiple differential gear sets 71 to rotate through the rotating gear 721. The differential gear set 71 engages with the tooth groove 444 on the outer wall of the corresponding synchronous cylinder 44 through the arc-shaped notch 31, so that the rotation speeds of the multiple synchronous cylinders 44 are different, and then the sliding time of the multiple synchronous tubes is different, which can make the thin steel wire tightened in sections along the length direction in sequence, not only can it avoid the thin steel wire from bending under the action of gravity due to the long distance; it can also make the thin steel wire always keep the straightened state when being straightened by the V-shaped limit plate 43, thereby improving the straightening effect of the V-shaped limit plate 43.

[0048] See also Figures 5 to 8 As shown, a plurality of second elastic telescopic rods 412 are circumferentially arranged on the inner wall of each positioning tube 41 along the axial direction, and a positioning roller 413 is arranged at one end of each second elastic telescopic rod 412 away from the inner wall of the positioning tube 41, and each positioning roller 413 is arranged at an acute angle to the axis of the positioning tube 41 in the length direction.

[0049] By providing a plurality of second elastic telescopic rods 412, the positioning rollers 413 at the ends of the second elastic telescopic rods 412 can contact with the surface of the thin steel wire, which can not only assist the movement of the thin steel wire, but also perform secondary straightening on the thin steel wire; and when two adjacent V-shaped limit plates 43 are separated, the position of the thin steel wire is adjusted so that it can always be located at the center of the positioning tube 41, thereby ensuring the accuracy of subsequent movement of the thin steel wire.

[0051] In order to be able to adapt to thin steel wires of different specifications and avoid excessive extrusion between the V-shaped limiting plate 43 and the thin steel wire during the straightening process, which may cause the thin steel wire to break; by providing an adjusting ring 52, after the staff inserts the thin steel wire between two adjacent V-shaped limiting plates 43, by rotating the adjusting ring 52, the adjusting ring 52 can rotate along the axis direction of the corresponding mounting tube 3, so that the semi-circular pressing block 521 on the adjusting ring 52 can contact the second arc-shaped guiding block 512 at the end of the corresponding sliding bar 51, so that multiple sliding bars 51 can overcome the elastic force of the corresponding second return spring 513 and move synchronously towards the axis direction of the positioning tube 41, so that the triangular guiding blocks 511 on multiple sliding bars 51 can move synchronously, thus forming a "toroidal surface" that cooperates with the first arc-shaped guiding block 421 to limit the maximum distance of movement of the V-shaped limiting plate 43, enabling it to adapt to thin steel wires of different specifications and avoiding "excessive抵触" to the thin steel wire, resulting in the breakage of the thin steel wire; through the setting of the first return spring 422, the moving bar 42 can be quickly reset, enabling the V-shaped limiting plate 43 to straighten the peripheral surface of the thin steel wire along the "toroidal surface"; the setting of the second return spring 513 enables the triangular guiding block 511 on the sliding bar 51 to move towards the inner wall direction of the mounting tube 3, ensuring that the semi-circular pressing block 521 on the adjusting ring 52 can accurately contact the second arc-shaped guiding block 512 on the sliding bar 51, thereby ensuring the consistency of the positions of multiple sliding bars 51.

[0052] See Figure 1 、 Figure 3 and Figure 8 As shown in

[0053] By driving the synchronous shaft 82 to rotate through the synchronous motor 83, the synchronous shaft 82 drives multiple adjusting rings 52 to rotate through multiple synchronous gears 821, so that the positions of the sliding bars 51 on multiple mounting tubes 3 can be synchronously adjusted, enabling the V-shaped limiting plate 43 to adapt to thin steel wires of different specifications. This can not only simplify the operation steps of the staff but also ensure the accuracy of the position of the V-shaped limiting plate 43 during the straightening process of the thin steel wire.

[0054] See Figure 1 and Fig.12 As shown, the traction mechanism 6 includes a traction plate 61 and a sliding block 62; the traction plate 61 is vertically arranged at one end of the top of the workbench 1 away from the coil rack 11, and a guide groove 611 is arranged on the traction plate 61. There are two sliding blocks 62, and the two sliding blocks 62 are both slidably arranged in the guide groove 611. A first bidirectional screw rod 612 is rotatably arranged in each guide groove 611, and both ends of the first bidirectional screw rod 612 are respectively threadedly connected to the corresponding sliding block 62, and a motor compartment 621 is also arranged on each sliding block 62, and a traction motor 622 is arranged in the motor compartment 621, and a traction roller 623 is arranged on the motor shaft of the traction motor 622.

[0056] See also Figure 1 and Fig.12 As shown, a guide rail 12 is provided at one end of the top of the workbench 1 close to the coil rack 11, and the guide rail 12 is arranged in a vertical state. Two clamping blocks 13 are slidably arranged in the guide rail 12, and an auxiliary roller 131 is rotatably arranged on each clamping block 13; a second bidirectional screw rod 121 is rotatably arranged in the guide rail 12, and both ends of the second bidirectional screw rod 121 are threadedly connected with the corresponding clamping blocks 13.

[0057] In order to better straighten the thin steel wire, the second bidirectional screw 121 is adjusted so that the two auxiliary rollers 131 can clamp the thin steel wire. At this time, the thin steel wire between the guide rail 12 and the traction plate 61 is on the same horizontal plane to avoid secondary bending of the thin steel wire after straightening.
