Description

Technical Field

[0001] This utility model relates to the field of materials processing engineering technology, specifically to a Stellite alloy heat treatment equipment. Background Technology

[0002] Stellite alloys, as high-performance cobalt-based alloys, are widely used in aerospace, energy, chemical, and medical fields due to their excellent wear resistance, corrosion resistance, and high-temperature strength. Heat treatment is a crucial step in the production process of Stellite alloys. By precisely controlling temperature, time, and cooling rate, the microstructure and mechanical properties of the alloy can be optimized to meet the needs of different application scenarios. With the development of industrial automation and intelligence, the technological level of heat treatment equipment directly affects production efficiency, product quality, and enterprise competitiveness.

[0031] like Figures 1 to 8 As shown, this Stellite alloy heat treatment equipment includes a body 1, heating elements 11, a top cover 2, multiple hook-type material racks 3, and multiple assembly mechanisms 4. The body 1 is the core component of the heat treatment equipment, and its interior forms a heat treatment chamber for accommodating Stellite alloy materials. An opening is provided at the top of the body 1 for connection with the top cover 2, facilitating the insertion and removal of the hook-type material racks 3. The heating elements 11 are fixedly installed on the inner wall of the body 1, employing resistance wire heaters or infrared heating tubes, and are evenly distributed circumferentially along the inner wall of the body 1 to ensure a uniform temperature field inside the heat treatment chamber. The power cord of the heating elements 11 is led out through a sealed wiring hole on the side wall of the body 1 and electrically connected to an external control system for precise control of heating temperature and heating time. The top cover 2 matches the shape of the opening at the top of the body 1. The top cover 2 is fixed to the top of the body 1 through a sealed connection to ensure the airtightness of the heat treatment chamber, preventing heat loss and the entry of external impurities. The bottom of the top cover 2 is used to install the hook-type material racks 3 and the assembly mechanisms 4. The hook-type rack 3 is used to suspend Stellite alloy workpieces, ensuring that the workpieces are stably suspended and heated evenly during heat treatment. The assembly mechanism 4 is fixedly installed at the bottom of the top cover 2 and is used to detachably connect the hook-type rack 3. The assembly mechanism 4 facilitates the installation and replacement of the hook-type rack 3 by the operator.

[0032] In actual use, the operator first hangs the Stellite alloy workpieces one by one on the hooks of the hook-type material rack 3, and then uses the assembly mechanism 4 to fix the hook-type material rack 3. It can be adapted to install hook-type material racks 3 of different specifications and multiple sets of hook-type material racks 3.

[0033] In this embodiment, the mounting assembly mechanism 4 includes a slide rail 41 and mounting components 42. The slide rail 41 is fixedly mounted on the bottom of the top cover 2. A linear guide groove is provided on the slide rail 41 to guide the sliding of the mounting components 42 and ensure stable positioning. Multiple sets of mounting components 42 can be mounted on the slide rail 41, each set used to fix a hook-type material rack 3. The cooperative design of the slide rail 41 and the mounting components 42 allows multiple sets of mounting components 42 to move and be positioned flexibly on the slide rail 41, thereby achieving rapid installation and adjustment of the hook-type material rack 3.

[0034] In actual use, before installing the hook-type material rack 3, the operator places the mounting component 42 on the slide rail 41. The mounting component 42 slides along the length of the slide rail 41, and the track structure of the slide rail 41 guides its movement direction, ensuring a smooth sliding process. According to the arrangement requirements of the hook-type material rack 3, the operator slides the mounting component 42 to the predetermined position. Multiple mounting components 42 can be positioned sequentially on the same slide rail 41 to accommodate Stellite alloy workpieces of different batches or specifications.

[0035] In this embodiment, the mounting assembly 42 includes multiple roller frames 421 and multiple pulleys 422. The roller frames 421 are independent frame structures made of high-temperature and corrosion-resistant metal materials such as stainless steel or nickel-based alloys to adapt to the high-temperature environment of the heat treatment chamber. The bottom of the roller frame 421 is connected to the top of a hook-type material rack 3. Two pulleys 422 are installed inside the roller frame 421. The two pulleys 422 are symmetrically distributed inside the roller frame 421 and slide in contact with the slide rail 41. The upper surface or side of the slide rail 41 is provided with guide grooves. The roller frame 421 slides along the same slide rail 41 via its pulleys 422, enabling flexible installation and positioning of multiple sets of hook-type material racks 3. The bottom of the roller frame 421 is fixedly connected to the top of the hook-type material rack 3. The hook-type material rack 3 is adjusted and installed by the sliding of the pulleys 422 of the roller frame 421 on the slide rail 41.

[0036] In actual use, before installing the hook-type material rack 3, the operator aligns the two pulleys 422 of the roller frame 421 with the guide grooves of the slide rail 41 and inserts it into the slide rail 41. The pulleys 422 contact the guide grooves of the slide rail 41 and slide smoothly along the slide rail 41 through rolling motion. The symmetrical arrangement of the two pulleys 422 ensures that the roller frame 421 remains balanced during sliding, reducing the risk of tilting or jamming. After the roller frame 421 slides to the predetermined position on the slide rail 41, the operator fixes the hook-type material rack 3. After fixing, the hook-type material rack 3 is connected to the roller frame 421 and can move on the slide rail 41 with the rolling of the pulleys 422. Depending on the number and size of the heat-treated workpieces, the operator can push the roller frame 421 to make its pulleys 422 slide along the slide rail 41 to the optimal position. After reaching the target position, it is fixed. After heat treatment is completed, the operator releases the roller frame 421 from the slide rail 41. Subsequently, the connection between the hook-type material rack 3 and the bottom of the roller frame 421 is disassembled, and the hook-type material rack 3 is removed. If it is necessary to adjust or replace the roller frame 421, the pulley 422 can be slid along the slide rail 41 to the end of the guide groove and removed. The entire process does not require disassembling the slide rail 41, making the operation highly efficient.

[0037] In this embodiment, the clamping assembly 43 includes multiple first slots 431, multiple supports 432, a base plate 433, a sliding plate 434, and multiple locking blocks 435. Each end of the slide rail 41 has a pair of first slots 431, symmetrically distributed on both sides of the end of the slide rail 41. A support 432 is fixedly mounted at the bottom of each first slot 431. The support 432 is a hollow rectangular structure connected to the bottom of the slide rail 41, and its inner wall has a vertical guide groove for guiding the sliding plate 434 up and down. The base plate 433 is a flat plate structure fixedly connected to the bottom of one of the supports 432. The base plate 433 is sealed to the bottom of the support 432, closing the lower end of the support 432 and forming a limiting structure for the sliding of the sliding plate 434. The sliding plate 434 is disposed inside the support 432 and slidably connected to the guide groove or slide rail on the inner wall of the support 432. Two locking blocks 435 are connected to the top of the slide plate 434. The locking blocks 435 are columnar or block-shaped structures. The locking blocks 435 are fixed to the top of the slide plate 434, and their upper ends pass through the first locking groove 431 and fit against the side wall or inner wall of the guide groove of the slide rail 41. The size of the locking blocks 435 matches the first locking groove 431, and they can slide or be fixed within the first locking groove 431. The contact surface of the locking blocks 435 with the slide rail 41 is smooth and has a certain degree of elasticity to provide a stable clamping force when pressed against the pulley 422.

[0038] In actual use, before the pulley 422 enters the slide rail 41, the locking block 435 penetrates the first locking groove 431, with its upper end fitting against the side wall or inner wall of the guide groove of the slide rail 41. The slide plate 434 is located at a higher position within the support 432, with a gap between its bottom and the base plate 433. At this time, the locking block 435 partially extends into the sliding path of the slide rail 41, in a ready-to-contact state. The pulley 422 enters and compresses. When the pulley 422 of the roller frame 421 slides into the guide groove of the slide rail 41, the outer edge of the pulley 422 first contacts the extended portion of the locking block 435 and applies a compressive force to it. The compressive force is transmitted to the slide plate 434 through the locking block 435, pushing the slide plate 434 downward along the guide groove of the support 432. The slide plate 434 slides downward, causing the locking block 435 to move downward synchronously, gradually disengaging the locking block 435 from the extended position of the first locking groove 431, making room for the pulley 422 to slide. After pulley 422 fully enters slide rail 41 and passes the position of block 435, the squeezing force disappears.

[0039] In this embodiment, the reset assembly 44 includes multiple movable rods 441 and multiple springs 442. The movable rods 441 are elongated rod-shaped structures. The upper end of the movable rod 441 is connected to the sliding plate 434, and the lower end passes through a pre-drilled hole in the base plate 433 and is slidably connected to the base plate 433. The lower end of the movable rod 441 is provided with a flange or a limiting block to prevent it from completely detaching from the base plate 433, while ensuring stability during sliding. The reset assembly 44 includes springs 442, which are compression springs to ensure stable elastic performance even under high-temperature heat treatment conditions. The springs 442 are sleeved on the outside of the movable rods 441, with one end fixedly connected to the top of the base plate 433 and the other end fixedly connected to the bottom of the sliding plate 434. Spring 442 is in a slightly compressed state in its natural state, providing an upward preload to slide plate 434, ensuring that block 435 fits against slide rail 41 when no external force is applied. By setting the upper guide part of block 435 as an inclined surface, it is convenient to put the hook-type material rack 3 without pulling slide plate 434.

[0040] In actual use, when the assembly mechanism 4 is running, the slide plate 434 drives the movable rod 441 connected to it to move. The movable rod 441 slides on the base plate 433 at the end away from the locking block 435. During this process, the spring 442 is deformed by the compression caused by the movement of the slide plate 434 and accumulates elastic potential energy. When the assembly mechanism 4 completes a specific operation or the external force disappears, the spring 442 releases the elastic potential energy, pushes the slide plate 434 to move in the opposite direction, and the slide plate 434 drives the movable rod 441 to reset, thereby restoring the assembly mechanism 4 to its initial state and completing the reset process.

[0041] In this embodiment, the connecting unit 5 includes multiple mounting plates 51, multiple locking plates 52, multiple second locking slots 53, multiple guide parts 531, multiple buffer parts 532, multiple locking parts 533, and multiple first locking rods 54. The uppermost mounting plate 51 is fixed to the bottom of the top cover 2, and the bottom surfaces of the remaining mounting plates 51 are connected to the top of the slide rail 41, facilitating the stacking of multiple workpieces. Two first locking rods 54 are connected to each side of the mounting plate 51, forming a symmetrical connecting structure. Two locking plates 52 are connected to the top of the slide rail 41. The inner walls of the locking plates 52 are fitted against the outer walls of the mounting plates 51, and their bottoms are fixedly connected to the top of the slide rail 41. Two sets of second locking slots 53 are provided on the locking plates 52, corresponding to the first locking rods 54 on both sides of the mounting plates 51, for realizing a detachable connection between the locking plates 52 and the mounting plates 51. The second slot 53 is a slot structure that penetrates the card plate 52. Each set of second slots 53 includes three sequentially connected areas: a guide portion 531, a buffer portion 532, and a locking portion 533. The guide portion 531 is located at the end of the second slot 53 and extends to the end face of the card plate 52, facilitating the smooth entry of the first locking rod 54 into the second slot 53. The opening design of the guide portion 531 reduces the alignment difficulty when the first locking rod 54 enters, improving installation efficiency. The buffer portion 532 is connected to the guide portion 531 and is the middle section of the second slot 53. It has an arc-shaped structure and serves as a buffer area for the first locking rod 54 to transition from the guide portion 531 to the locking portion 533, allowing the first locking rod 54 to fine-tune its position during sliding and reducing the impact force during locking. The locking portion 533 is located at the end of the second slot 53 and is connected to the buffer portion 532. It is the fixing area of ​​the slot, and the inner wall of the locking portion 533 fits against the first locking rod 54 to form a stable locking fixation. Two first locking rods 54 are fixedly connected to each side of the mounting plate 51. The first locking rods 54 are fixed to the side of the mounting plate 51 and can pass through the guide part 531, the buffer part 532 and the locking part 533 in sequence, and finally fit and fix with the locking part 533.

[0042] In actual use, the uppermost mounting plate 51 is fixed to the bottom of the top cover 2, and the first locking rods 54 on both sides of the mounting plate 51 are in a cantilevered state. The locking plate 52 is fixedly connected to the slide rail 41 through its bottom, and the second locking groove 53 on the locking plate 52 is aligned with the first locking rod 54 of the mounting plate 51, ready for locking. The operator aligns the locking plate 52 together with the slide rail 41 with the mounting plate 51, so that the opening of the guide part 531 of the second locking groove 53 is aligned with the first locking rod 54. The flared shape of the guide part 531 guides the first locking rod 54 smoothly into the second locking groove 53, reducing the difficulty of alignment. The operator pushes the locking plate 52, so that the first locking rod 54 slides along the guide part 531 into the interior of the second locking groove 53. The first locking rod 54 slides from the guide part 531 into the buffer part 532. The smooth transition design of the buffer part 532 ensures that the first locking rod 54 can slide smoothly to the locking part 533. The first locking rod 54 continues to slide to the locking part 533. The locking part 533 is designed to open vertically downward and connect to the buffer part 532. The design can utilize the gravity of the locking plate 52 to enhance the fixing effect and prevent the first locking rod 54 from loosening.

[0043] In this embodiment, the air gap adjustment device 6 includes an inlet pipe 61, a cylinder 62, an outer cylinder 63, and a threaded rod 64. The inlet pipe 61 is a high-temperature resistant and corrosion-resistant metal pipe, such as stainless steel or nickel-based alloy, which penetrates the side wall of the machine body 1. One end of the inlet pipe is connected to an external gas source, such as an inert gas supply device, and the other end is connected to the inside of the cylinder 62. The inlet pipe 61 is fixed to the machine body 1 through a sealing joint, such as a flange or threaded connection, to ensure airtightness and prevent gas leakage. The cylinder 62 is a hollow cylindrical or rectangular cavity made of a high-temperature resistant material, such as high-temperature ceramic or stainless steel, and is fixedly installed on the inner wall of the machine body 1 and connected to the inlet pipe 61. The inner cavity of the cylinder 62 serves as a gas buffer and distribution area, and its surface is evenly distributed with multiple micro-holes or nozzles for releasing gas into the heat treatment chamber to form a uniform air gap environment. The cylinder 62 is firmly connected to the inner wall of the machine body 1, and its outer surface is tightly fitted to the outer cylinder 63. The outer cylinder 63 is a sleeve structure that matches the shape of the cylinder body 62, fitting around the outside of the cylinder body 62 and slidingly adhering to its outer surface. The end of the outer cylinder 63 is fixedly connected to the end of the threaded rod 64, used to transmit the movement of the threaded rod 64. The threaded rod 64 is a long, threaded component that passes through the top cover 2 and the mounting frame 21 sequentially, and is threadedly connected to both the top cover 2 and the mounting frame 21. The external thread of the threaded rod 64 matches the internal threaded holes of the top cover 2 and the mounting frame 21. Rotating the threaded rod 64 enables its axial lifting and lowering movement, thereby driving the outer cylinder 63 to slide along the cylinder body 62. A handle is provided at the top of the threaded rod 64 for easy manual adjustment. The mounting frame 21 is fixed to the bottom of the top cover 2. The mounting frame 21 is connected to the hydraulic cylinder 22 at its bottom, providing auxiliary support for the movement of the top cover 2. The structural strength of the mounting frame 21 is sufficient to withstand the weight of the top cover 2 and the hook-type material rack 3. Hydraulic cylinders 22: Two hydraulic cylinders 22 are respectively located on both sides of the machine body 1. They adopt high-temperature resistant pneumatic components. The hydraulic cylinders 22 are driven by an external air source and can push the mounting frame 21 and the top cover 2 to rise and fall vertically, assisting the opening and closing of the top cover 2 and ensuring its sealed connection with the machine body 1. They also push the top cover 2 to remove the device inside the top cover 2 from the machine body 1. Pressure relief valve 12 is an automatic regulating valve, installed on the side wall or top of the machine body 1. The pressure relief valve 12 is connected to the inside of the heat treatment chamber and regulates the pressure inside the chamber through an electromagnetic control mechanism. When the internal pressure exceeds a set threshold, it automatically opens to release gas and prevent overpressure. The flow rate and response speed of the pressure relief valve 12 are designed to quickly balance the pressure inside the chamber. Temperature sensor 13 is a high-precision thermocouple or infrared temperature measuring element, installed on the inner wall or side wall of the machine body 1, used to monitor the internal temperature of the heat treatment chamber in real time. The temperature sensor 13 is fixed to the machine body 1 through a sealed joint, and its signal line is led out to an external control system to provide temperature data for precise control of the working state of the heating element 11. The measurement range and accuracy of temperature sensor 13 are adapted to the temperature requirements of Stellite alloy heat treatment.

[0044] In actual use, before heat treatment begins, the operator rotates the threaded rod 64 to raise and lower it along the threaded holes of the top cover 2 and the mounting frame 21. The movement of the threaded rod 64 causes the outer cylinder 63 to slide axially along the cylinder body 62, adjusting the degree of coverage of the outer cylinder 63 over the micro-holes or nozzles on the surface of the cylinder body 62, thereby controlling the amount and distribution of gas release and forming the required air gap environment in the heat treatment chamber. After adjustment, the threaded rod 64 is fixed by threaded self-locking to ensure the stability of the outer cylinder 63. An external gas source inputs inert gas, such as argon or nitrogen, into the cylinder body 62 through the gas inlet pipe 61. After being buffered inside the cylinder body 62, the gas is evenly released into the heat treatment chamber through the surface micro-holes or nozzles. The sliding position of the outer cylinder 63 determines the degree of opening of the micro-holes, thereby precisely adjusting the thickness of the air gap and the gas flow field distribution, optimizing heat transfer and the uniformity of workpiece heating. Before installing the hook-type material rack 3, the hydraulic cylinder 22 is driven by an external air source, and the piston rod pushes the mounting frame 21 and the top cover 2 upward to open the top opening of the machine body 1, facilitating the installation of the hook-type material rack 3. After loading, the hydraulic cylinder 22 reverses its direction, causing the top cover 2 to descend and form a sealed connection with the top of the machine body 1 through a sealing gasket. The mounting frame 21 provides stable support for the threaded rod 64 and the top cover 2, ensuring smooth movement. Temperature and pressure control: During heat treatment, the temperature sensor 13 monitors the temperature of the heat treatment chamber in real time and transmits the data to the external control system to adjust the power of the heating element 11, ensuring uniform temperature and compliance with process requirements. The pressure relief valve 12 monitors the pressure inside the chamber and automatically opens when the pressure exceeds the safety threshold to release excess gas and maintain stable pressure inside the chamber. The air gap adjustment device 6, through the adjustment of the gas input and the outer cylinder 63, works in conjunction with temperature and pressure control to form a stable heat treatment environment. Disassembly and maintenance: After heat treatment, the hydraulic cylinder 22 drives the top cover 2 to open again, and the operator removes the hook-type material rack 3. If maintenance of the air gap adjustment device 6 is required, the position of the outer cylinder 63 can be adjusted by rotating the threaded rod 64, or the air inlet pipe 61 can be disassembled for cleaning. The entire process does not require disassembling the machine body 1, making it easy to operate.
