Description

Technical Field

[0002] Nickel alloys, with their excellent high-temperature strength, superior corrosion resistance, and good oxidation resistance, have become ideal materials for manufacturing fasteners in high-end industries such as aerospace, shipbuilding, and energy and chemical industries. In these fields, there are extremely stringent requirements for the performance and quality of nickel alloy fasteners. Heat treatment is a key process that determines their final performance. However, existing heat treatment equipment for processing and manufacturing nickel alloy fasteners has many shortcomings.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0023] Example 1: See Figures 1-6 The present invention provides a technical solution: a heat treatment equipment for processing and manufacturing nickel alloy fasteners, comprising a heat treatment chamber 1, a heat treatment equipment body 2 fixedly connected to the outer surface of the heat treatment chamber 1, a limiting mechanism 3 provided on the inner wall of the heat treatment chamber 1, a material placement mechanism 4 threadedly connected inside the limiting mechanism 3, an auxiliary mechanism 5 slidably connected to the outer surface of the limiting mechanism 3, a first fastener 6 and a second fastener 7 inserted inside the material placement mechanism 4, and a first material tray 8 snapped onto the outer surface of the material placement mechanism 4. The limiting mechanism 3 includes: The rough-surfaced column 301 is in contact with the inner wall of the heat treatment chamber 1. The outer surface of the rough-surfaced column 301 is fixedly connected with a lifting lug 302. The inside of the rough-surfaced column 301 is rotatably connected with a limiting shaft 303. The outer surface of the limiting shaft 303 is fixedly connected with an internal threaded sleeve 304. The lifting lug 302 is used to lift the limiting mechanism 3.

[0024] The internal threaded sleeve 304 is internally threaded with a first threaded post 305. The outer surface of the internal threaded sleeve 304 is provided with a bolt face 306. The outer surface of the first threaded post 305 is fixedly connected with a through hole plate 307. The outer surface of the through hole plate 307 is fixedly connected with a bellows 308. The internal threaded sleeve 304 is used to push the first threaded post 305.

[0025] The contact surface between the roughened column 301 and the outer surface of the internal threaded sleeve 304 is a smooth surface. The outer surface of the bellows 308 is fixedly connected to the outer surface of the internal threaded sleeve 304. The outer surface of the internal threaded sleeve 304 is provided with two bolt surfaces 306. The bellows 308 is used to protect the first threaded column 305. When the internal threaded sleeve 304 and the first threaded column 305 are threadedly connected, the bellows 308 protects them. Through the bidirectional pushing of the symmetrically arranged limiting mechanism 3, the through hole plate 307 is kept horizontal with the heat treatment box 1, ensuring that it will not affect the material feeding mechanism 4.

[0026] The material placement mechanism 4 includes a support threaded column 401, which is threadedly connected to the through hole plate 307. The outer surface of the support threaded column 401 is threadedly connected to a bolt sleeve 402. The inside of the support threaded column 401 is engaged with a second limiting shaft 403. The inside of the second limiting shaft 403 is rotatably connected to a material tray frame 404. The inside of the material tray frame 404 is engaged with a first slot 405. The inside of the material tray frame 404 is engaged with a second lifting lug 406, which is used to lift the material placement mechanism 4.

[0027] The material feeding mechanism 4 also includes a first locking block 407, which is engaged with a first locking groove 405. A steel wire rope 408 is fixedly connected to the outer surface of the first locking block 407. The steel wire rope 408 is inserted into a fastener 6. A steel wire rope 409 is inserted into the inside of the fastener 6. A grooved cylinder 410 is fixedly connected to the outer surface of the steel wire rope 409. A protruding cylinder 411 is engaged inside the grooved cylinder 410. The material tray frame 404 and the lifting lug 406 are engaged with a limiting hole 412. The steel wire rope 408 and the steel wire rope 409 suspend the fastener 6 and the fastener 7.

[0028] The first wire rope 408 is inserted into the second fastener 7, the tray frame 404 is snapped into the first tray 8, the outer surface of the protruding cylinder 411 is fixedly connected to the outer surface of the second wire rope 409, the upper surface of the first locking block 407 is flush with the upper surface of the tray frame 404, the bolt sleeve 402 is used to limit the support threaded column 401, the locking of the support threaded column 401 and the limiting rotating shaft 403 can be released, so that the tray frame 404 and the limiting rotating shaft 403 can be moved out and lifted separately by the second lifting lug 406, which facilitates the remaining heat treatment operations.

[0029] The working principle of this embodiment is as follows: When using this heat treatment equipment for nickel alloy fastener processing and manufacturing, the limiting mechanism 3 and the material placement mechanism 4 are suspended inside the heat treatment chamber 1 by the lifting lug 302. The internal threaded sleeve 304 is rotated by the bolt face 306, which in turn drives the limiting shaft 303 to rotate, thereby pushing the roughened column 301 to move in a limited position. It cooperates with the symmetrically arranged roughened column 301 and internal threaded sleeve 304, and is supported by the first threaded column 305 in a bidirectional spiral manner, so that it is the same length as the heat treatment chamber 1, and provides horizontal support for the limiting mechanism 3. At the same time, the bolt sleeve 402 limits the support threaded column 401, so that the support threaded column 401 contacts the inner wall of the heat treatment chamber 1. At this time, the fastener 6 is wound by the first locking block 407 and the steel wire rope 408, and is suspended by the engagement of the first locking block 407 and the first locking groove 405. The device can be suspended by inserting additional fasteners 6 via steel wire rope 409 and engaging with grooved cylinder 410 and protruding cylinder 411. Multiple sets of first locking blocks 407 can be used in conjunction with steel wire rope 408 to suspend larger fasteners 6 and different fasteners 7. When suspending smaller fasteners is inconvenient, a first tray 8 can be engaged inside the tray frame 404 for placing smaller fasteners. The tray frame 404, containing fasteners 6 and 7, is then suspended by lifting lug 406, engaging with limiting pivot 403 and supporting threaded column 401 to place the fasteners. Heat treatment is then performed through the heat treatment chamber 1 and the heat treatment equipment body 2. After completion, the heat-treated fasteners can be lifted using lifting lug 406 to complete the remaining heat treatment operations.

[0030] Example 2: Please refer to Figures 7-9 Based on Embodiment 1, the present invention provides a technical solution: the auxiliary mechanism 5 includes an arc-shaped plate 501, which is engaged with a limiting hole 412. A lifting lug sleeve 502 is fixedly connected to the lower surface of the arc-shaped plate 501. A second threaded post 503 is threadedly connected to the inside of the lifting lug sleeve 502. A through-hole slider 504 is rotatably connected to the outer surface of the second threaded post 503. A connecting rod 505 is fixedly connected to the outer surface of the through-hole slider 504. A rotating sleeve 506 is threadedly connected to the inside of the lifting lug sleeve 502. An arc-shaped plate 507 is rotatably connected to the outer surface of the rotating sleeve 506. A second slot 508 is engaged inside the arc-shaped plate 507. The arc-shaped plate 501 is used to support the material tray frame 404.

[0031] The second threaded post 503 and the outer surface of the rotating sleeve 506 are provided with bolt surfaces 306. The through-hole slider 504 is slidably connected to the outer surface of the internal threaded sleeve 304. The second slot 508 is engaged with the first locking block 407. The connecting rod 505 is used to limit the auxiliary mechanism 5. The second threaded post 503 and the outer surface of the lifting lug sleeve 502 are provided with bolt surfaces 306, which facilitates the adjustment of the distance between the lifting lug sleeve 502 and the rotating sleeve 506, and between the lifting lug sleeve 502 and the second threaded post 503. When adjusting the position of the arc plate 507, the position difference between the left and right sides can be adjusted to achieve vertical fixation of fasteners at different height positions.

[0032] The working principle of this embodiment is as follows: When using this heat treatment equipment for nickel alloy fastener processing and manufacturing, during the separate hoisting of the second limiting shaft 403 and the material tray frame 404, the through-hole slider 504 slides on the outer surface of the internal threaded sleeve 304, so that the arc plate 501 and the limiting hole 412 are perpendicularly opposite each other. At this time, the second threaded column 503 rotates, pushing the arc plate 501 to move through the lifting lug sleeve 502, making it flush with the limiting hole 412 when the second limiting shaft 403 and the supporting threaded column 401 are engaged. At the same time, the connecting rod 505 is connected to the symmetrically arranged auxiliary mechanisms 5, thereby maintaining the overall stability of the two auxiliary mechanisms 5. At this time, the material tray frame 404 with fasteners, the second limiting shaft 403 and the supporting threaded column 401 are engaged. This allows the limiting hole 412 to engage with the arc-shaped plate 501, thus providing auxiliary support for the tray frame 404 with fasteners. At this time, the first locking block 407 is engaged inside the second locking groove 508, and the fasteners at the bottom are inserted or wrapped by the steel wire rope 408, and engaged with the symmetrically arranged arc-shaped plate 507. At this time, the rotation of the rotating sleeve 506 drives the arc-shaped plate 507 to move downward, thereby vertically limiting the fasteners with the steel wire rope 408 to prevent them from shaking. At this time, heat treatment is performed through the heat treatment box 1 and the heat treatment equipment body 2. After completion, the entire equipment can be hoisted by the lifting lug 302 to ensure that the fasteners do not shake during the movement and to ensure that the remaining heat treatment operations of the fasteners are not affected.
