Technical Field

[0001] The invention belongs to the technical field of nickel-based alloy wires, and in particular relates to an online annealing and straightening device for nickel-based alloy wires. Background Art

Different nickel-based alloys have different functions, and in some scenarios, nickel-based alloy wires are needed, which are in the shape of wires as a whole. After processing, nickel-based alloy wires need to be annealed online, usually by slowly heating them and then slowly cooling them, which can reduce residual stress, stabilize dimensions, and reduce deformation and cracking tendencies. During the processing of nickel-based alloy wires, some bending may occur and they need to be straightened after heating.

[0027] Preferably, a shift block is installed on the top of the adjusting block.

[0028] Preferably, the heating box is provided with side openings opposite to each other for the nickel-based alloy wire to pass through.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. The present invention provides an online annealing and straightening device for nickel-based alloy wires. The nickel-based alloy wires are sequentially moved on the correction block assembly, the tension adjustment assembly, the heating box and the winding roller assembly. After the correction block assembly pre-presses the nickel-based alloy wires, the nickel-based alloy wires are preliminarily straightened. When the nickel-based alloy wires have a large curvature, when the correction block assembly pre-presses the nickel-based alloy wires, the correction block assembly drives the tension adjustment assembly to work through the transmission assembly arranged in the action chamber. The tension adjustment assembly adjusts the tension of the nickel-based alloy wires after the preliminary straightening, so that the nickel-based alloy wires always maintain tension. After the preliminary straightening, the nickel-based alloy wires pass through the heating box and are wound on the winding roller assembly. The winding roller assembly performs secondary straightening on the nickel-based alloy wires. In this way, the correction block assembly performs preliminary straightening on the nickel-based alloy wires, and the winding roller assembly performs secondary straightening on the nickel-based alloy wires, thereby improving the straightening effect, and the tension adjustment assembly automatically completes the tension adjustment of the nickel-based alloy wires.

[0031] 2. The present invention provides an online annealing and straightening device for nickel-based alloy wires. The adjusting block is manually pushed to move in the direction of approaching the central fixed cylinder in the limit vertical groove. The adjusting block drives the rotating rod to rotate in the central fixed cylinder through the adjusting rod. The steel ropes connected to the two ends of the rotating rod through the mounting column release the pulling on the flip frame. In this way, under the reset action of the reset spring, the flip shaft drives the flip frame, the adjusting rod connected to the flip frame, and the adjusting correction block connected to the adjusting rod to move along the limit horizontal groove toward the direction of approaching the fixed correction block. Because gear 2 is installed on the flip shaft through a one-way ratchet transmission member, gear 2 does not rotate with the flip shaft, and the spline sleeve connected to the adjusting block through the adjusting horizontal frame slides on the spline shaft toward the direction of the transmission screw, and gear 1 installed on the spline sleeve gradually achieves meshing with gear 2. Because gear 2 does not rotate with the flip shaft and does not move, gear 1 will not drive the spline sleeve, the spline shaft connected to the spline sleeve, and the transmission screw connected to the spline shaft to rotate, and the transmission roller does not move. When the nickel-based alloy wire has a large curvature, when the large curvature part of the nickel-based alloy wire passes through the straightening channel, the fixed correction block and the adjusting correction block complete the pre-stressing on it. Because the fixed correction block is not moving, the adjusting correction block moves slightly in the direction away from the fixed correction block, and the adjusting correction block drives the flip shaft on the lower adjustment frame to rotate in the opposite direction through the flip frame. The steel rope loses tension, and the gear 2 connected to the flip shaft through the one-way ratchet transmission member rotates in the opposite direction. Gear 2 drives gear 1 installed on the spline sleeve to rotate, and gear 1 drives the spline sleeve, the spline shaft connected to the spline sleeve, and the drive screw connected to the spline shaft to rotate. The drive screw sleeve on the drive screw and the flip rod installed on the drive screw sleeve push the flip frame and the drive roller installed on the flip frame to lift. In this case, because the large curvature part of the nickel-based alloy wire is pre-stressed and initially straightened, the length of the nickel-based alloy wire increases when passing through the moving roller. At this time, if the drive roller is lifted, the tension of the nickel-based alloy wire is restored. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] The present invention will be further described below in conjunction with the accompanying drawings.

[0041] like Figures 1 to 5 As shown, the present embodiment provides an online annealing and straightening device for nickel-based alloy wire, comprising a base 10, and also comprising: a correction block assembly 11, a tension adjustment assembly 12, a heating box 13 and a winding roller assembly 14 which are sequentially installed on the base 10, an action chamber 15 is provided in the base 10, and a transmission assembly 16 which is linked to the correction block assembly 11 and the tension adjustment assembly 12 is installed in the action chamber 15.

[0042] The working principle and beneficial effects of the above technical solution are:

[0043] The present invention discloses an online annealing and straightening device for nickel-based alloy wires. The nickel-based alloy wires are sequentially moved on a correction block assembly 11, a tension adjustment assembly 12, a heating box 13, and a winding roller assembly 14. The correction block assembly 11 pre-presses the nickel-based alloy wires, thereby preliminarily straightening the nickel-based alloy wires. When the nickel-based alloy wires have a large curvature, when the correction block assembly 11 pre-presses the nickel-based alloy wires, the correction block assembly 11 drives the tension adjustment assembly 12 to work through a transmission assembly 16 disposed in an action chamber 15. The tension adjustment assembly 12 adjusts the tension of the nickel-based alloy wires after the preliminary straightening, so that the nickel-based alloy wires always maintain tension. After the nickel-based alloy wires after the preliminary straightening pass through the heating box 13, they are wound on the winding roller assembly 14, and the winding roller assembly 14 performs secondary straightening on the nickel-based alloy wires. The present invention provides an online annealing and straightening device for nickel-based alloy wires. The straightening block assembly 11 performs preliminary straightening on the nickel-based alloy wires, and the winding roller assembly 14 performs secondary straightening on the nickel-based alloy wires, thereby improving the straightening effect, and the tension adjustment assembly 12 automatically completes the tension adjustment of the nickel-based alloy wires.

[0044] In one embodiment, the correction block assembly 11 includes:

[0045] A fixed correction block 17 and an adjustable correction block 18, wherein the two fixed correction blocks 17 are fixedly mounted on the top of the base 10 through support rods respectively, and the two adjustable correction blocks 18 are located between the two fixed correction blocks 17, and a straightening channel for the nickel-based alloy wire to travel is formed between each fixed correction block 17 and the adjustable correction block 18;

[0046] The lower adjustment frame 19 is fixedly installed at the bottom of the action chamber 15;

[0047] The flip frame 20 is mounted on the lower adjustment frame 19 through a flip shaft 21. The flip frame 20 is telescopically mounted on the adjustment rod away from the flip shaft 21. A return spring 22 is sleeved on the flip shaft 21.

[0048] The limiting transverse groove is arranged at the top of the base 10 and is connected to the action chamber 15. The adjusting rod is slidably connected in the limiting transverse groove, and the adjusting and correcting block 18 is installed on the adjusting rod.

[0049] The working principle and beneficial effects of the above technical solution are:

[0050] The two adjusting and correcting blocks 18 move towards each other, so that the two nickel-based alloy wires pass through each straightening channel one by one. Then, after the two adjusting and correcting blocks 18 are released, under the reset action of the reset spring 22, the flip shaft 21 drives the flip frame 20, the adjusting rod connected to the flip frame 20, and the adjusting and correcting block 18 connected to the adjusting rod to move along the limiting transverse groove towards the direction of the fixed correction block 17, and the flip frame 20 extends away from the flip shaft 21 end, so that the fixed correction block 17 and the adjusting correction block 18 are pre-pressed on the nickel-based alloy wire located in the straightening channel, thereby performing preliminary straightening on the nickel-based alloy wire.

[0051] In one embodiment, the correction block assembly 11 further includes:

[0052] The central fixed cylinder 23 is fixedly installed at the bottom of the action chamber 15;

[0053] A rotating rod 24, both ends of which are rotatably mounted on the inner wall of the central fixed cylinder 23, and a mounting column is mounted on each of the positions of the rotating rod 24 near both ends;

[0054] Steel rope 25, the mounting column is connected with steel rope 25, and the steel rope 25 is connected to the flip frame 20 away from the end of the mounting column;

[0055] A limit vertical groove, which is provided at the top of the base 10 and communicated with the action chamber 15, wherein the adjustment block 26 is slidably connected to the limit vertical groove, and the transmission assembly 16 is connected to the adjustment block 26;

[0056] The adjusting rod 27 has one end rotatably mounted on the bottom end of the adjusting block 26 , and the other end of the adjusting rod 27 is rotatably connected to one of the mounting posts.

[0057] The working principle and beneficial effects of the above technical solution are:

[0058] The adjusting block 26 is manually pushed to move in the limit vertical slot toward the direction close to the central fixed cylinder 23, and the adjusting block 26 drives the rotating rod 24 to rotate in the central fixed cylinder 23 through the adjusting rod 27, and the steel rope 25 connected to both ends of the rotating rod 24 through the mounting column releases the pulling on the turning frame 20. In this way, under the reset action of the reset spring 22, the turning shaft 21 drives the turning frame 20, the adjusting rod connected to the turning frame 20, and the adjusting correction block 18 connected to the adjusting rod to move along the limit horizontal slot toward the direction close to the fixed correction block 17.

[0059] When it is necessary to adjust the adjusting correction block 18 to move along the limiting transverse groove away from the fixed correction block 17, the adjusting block 26 is manually pulled in the opposite direction to move in the limiting vertical groove away from the center fixed cylinder 23, and the adjusting block 26 drives the rotating rod 24 to rotate in the opposite direction in the center fixed cylinder 23 through the adjusting rod 27. The steel rope 25 connected to the two ends of the rotating rod 24 through the mounting column pulls the flip frame 20, and the flip frame 20 shrinks away from the flip axis 21 end. The adjusting rod connected to the flip frame 20 and the adjusting correction block 18 connected to the adjusting rod move along the limiting transverse groove away from the fixed correction block 17, and the nickel-based alloy wire in the straightening channel is untied.

[0060] In one embodiment, an annular groove is formed on the inner wall of the central fixing tube 23 to facilitate the sliding of the two ends of the rotating rod 24 .

[0061] The beneficial effects of the above technical solution are:

[0062] The provision of the annular groove enables the rotation rod 24 to be limited in position within the central fixing cylinder 23 .

[0063] In one example, the tension adjustment assembly 12 includes:

[0064] The transmission roller 28 is rotatably mounted on the top of the base 10 through the turning frame 29, and the nickel-based alloy wire runs on the transmission roller 28;

[0065] The flip rod 30 has one end rotatably mounted on the flip frame 29 , and a connecting vertical slot connected to the action chamber 15 is provided at the top of the base 10 , and the other end of the flip rod 30 extends from the connecting vertical slot into the action chamber 15 and is connected to the transmission assembly 16 .

[0066] The working principle and beneficial effects of the above technical solution are:

[0067] The nickel-based alloy wire runs on the transmission roller 28. When the tension of the nickel-based alloy wire needs to be adjusted, the flip rod 30 drives the flip frame 29 to rotate at the top of the base 10, thereby driving the transmission roller 28 installed on the flip frame 29 to adjust the height, thereby realizing the tension adjustment of the nickel-based alloy wire running on the transmission roller 28.

[0068] In one example, the transmission assembly 16 includes:

[0069] The transmission screw 31 and the spline shaft are coaxially connected and connected to the inner wall of the action chamber 15 through a mounting frame;

[0070] A transmission screw sleeve 32 is sleeved on the transmission screw rod 31, and the other end of the flip rod 30 is rotatably mounted on the transmission screw sleeve 32;

[0071] A spline sleeve 33, the spline sleeve 33 is sleeved on the spline shaft, the spline sleeve 33 is rotatably mounted on an adjustment cross frame 34, and the adjustment cross frame 34 is connected to the adjustment block 26 at the end away from the spline sleeve 33;

[0072] The gear 1 35 and the gear 2 36 can be meshed, the gear 1 35 is installed on the spline sleeve 33, and the gear 2 36 is installed on one end of the flip shaft 21 through a one-way ratchet transmission member.

[0073] The working principle and beneficial effects of the above technical solution are:

[0074] When the adjusting block 26 is manually pushed in the limiting vertical groove toward the direction approaching the center fixed cylinder 23, so that the adjusting correction block 18 is moved toward the direction approaching the fixed correction block 17, because the gear 2 36 is installed on the flip shaft 21 through the one-way ratchet transmission member, the gear 2 36 does not rotate with the flip shaft 21, and the spline sleeve 33 connected to the adjusting block 26 through the adjusting cross frame 34 slides on the spline shaft toward the direction approaching the transmission screw 31, and the gear 1 35 installed on the spline sleeve 33 gradually achieves meshing with the gear 2 36. Because the gear 2 36 does not rotate with the flip shaft 21 and does not move, the gear 1 35 will not drive the spline sleeve 33, the spline shaft connected to the spline sleeve 33, and the transmission screw 31 connected to the spline shaft to rotate, and the transmission roller 28 does not move.

[0075] When the nickel-based alloy wire has a large curvature, when the large curvature part of the nickel-based alloy wire passes through the straightening channel, the fixed correction block 17 and the adjusting correction block 18 complete the pre-compression thereof. Because the fixed correction block 17 is not moving, the adjusting correction block 18 moves slightly in the direction away from the fixed correction block 17. The adjusting correction block 18 drives the turning shaft 21 on the lower adjusting frame 19 to rotate in the opposite direction through the turning frame 20. The steel rope 25 loses its tension, and the gear 2 36 connected to the turning shaft 21 through the one-way ratchet transmission member rotates in the opposite direction. The gear 2 36 drives the gear 2 installed on the flower The gear 1 35 on the key sleeve 33 rotates, and the gear 1 35 drives the spline sleeve 33, the spline shaft connected to the spline sleeve 33, and the transmission screw 31 connected to the spline shaft to rotate. The transmission screw sleeve 32 on the transmission screw 31 and the flip rod 30 installed on the transmission screw sleeve 32 push the flip frame 29 and the transmission roller 28 installed on the flip frame 29 to lift. In this case, because the large curvature part of the nickel-based alloy wire is pre-stressed and initially straightened, the length of the nickel-based alloy wire increases when passing through the moving roller 28. At this time, if the transmission roller 28 is lifted, the tension of the nickel-based alloy wire is restored.

[0076] After the large curvature portion of the nickel-based alloy wire is pre-stressed and initially straightened, the reset spring 22 is reset, and the adjustment correction block 18 is reset. A reset coil spring is installed on the mounting frame connected to the transmission screw 31. Because gear 2 36 does not rotate in the opposite direction, the transmission screw 31 rotates in the opposite direction under the reset of the reset coil spring, and the transmission roller 28 falls. Because gear 1 35 rotates in the opposite direction, it will drive gear 2 36 to rotate forward. When gear 2 36 rotates forward, due to the existence of the one-way ratchet transmission component, it will not drive the flip shaft 21 to rotate forward synchronously.

[0077] In one example, the thickness of the gear 2 36 is greater than the thickness of the gear 1 35 .

[0078] In one embodiment, a shift block is installed on the top of the adjustment block 26 .

[0079] In one example, the heating box 13 is provided with side openings for the nickel-based alloy wire to pass through.

[0080] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
