Description
Technical Field
[0001] This application relates to the field of heat treatment technology for metallic materials, and in particular to a heat treatment apparatus and process for round plate products. Background Technology
[0002] Currently, steel is widely used, mainly in the processing of fasteners in the automotive and wind power industries, the processing of high-performance machine tool guideways and other components, and the processing of high-performance tunneling machine tools. Therefore, steel needs to be heat-treated before leaving the factory to improve its performance. Round plate steel is prone to deformation during heat treatment due to thermal stress and structural stress, resulting in dimensional deviations and affecting subsequent processing accuracy and performance. As the high-end equipment manufacturing industry places increasingly higher demands on the precision of parts, how to achieve near-net-shape forming during the heat treatment process has become a key technical challenge for the industry.
[0003] In existing technologies, heat treatment of steel is mainly divided into three methods: bottom-contact placement method: the workpiece is placed upright on the bottom of the furnace. The operation is simple, but stress concentration is prone to occur in the bottom contact area, resulting in an ellipticity deviation rate of more than 15% (flatness deviation rate of 90%); hanging and clamping method: the workpiece is suspended by special fixtures. Although it can avoid contact deformation, it requires pre-processing of lifting holes (increasing process costs), and single-point suspension is prone to causing circumferential asymmetric deformation; counterweight shaping method: a counterweight is applied to the top of the workpiece. Although it can suppress warping, it exacerbates the risk of grain boundary slip, leading to deterioration of the microstructure.
[0004] Regarding the aforementioned technologies, existing methods cannot simultaneously solve the problems of contact stress concentration, uneven gravity distribution, and thermal stress coordination, especially for precision parts without lifting holes, resulting in low quality of finished steel products. Summary of the Invention
[0005] In order to improve the quality of finished steel products, this application provides a heat treatment apparatus and process for round plate products.
[0006] In a first aspect, this application provides a heat treatment apparatus for circular plate products, employing the following technical solution: A heat treatment apparatus for round plate products includes a quenching component, a heating chamber, and a slide rail component. The slide rail component passes through the heating chamber and the slide rail component sequentially along one side of its length. Several heaters are fixed inside the heating chamber. A movable basket is provided at the upper end of the slide rail component. The slide rail component drives the movable basket to slide along the length of the slide rail component. Several partition columns are fixed at the upper end of the movable basket. The partition columns are arranged along the length of the movable basket, and a storage space is formed between two adjacent partition columns. Several guide columns are fixed vertically at the upper end of the movable basket. The same support plate is fixed at the upper end of the guide columns. A movable plate is provided at the lower end of the support plate. The guide columns pass through the movable plate, and the movable plate is slidably connected to the guide columns vertically. A hydraulic cylinder is fixed vertically at the upper end of the support plate. The hydraulic cylinder drives the movable plate to move vertically. A rotating component is provided inside the movable basket to rotate the steel. Several moving openings are opened at the upper end of the movable plate, which are directly opposite the storage space. Clamping components are provided in the moving openings to clamp and fix the steel.
[0007] By adopting the above technical solution, the lower end of the steel is located in the movable basket. The movable basket and the partition columns work together to separate and limit the steel. The slide rail assembly drives the movable basket into the heating chamber. The heater heats the steel, and the quenching assembly quenches the heated steel. The rotating assembly rotates all the steel. After heating, the slide rail assembly moves the movable basket out of the quenching assembly. The guide column and the support plate work together to support the hydraulic cylinder. The hydraulic cylinder drives the movable plate to descend. When the movable plate contacts the steel, the clamping assembly clamps the steel. The hydraulic cylinder and the movable plate work together to lift the clamping assembly and the steel. The operator moves the steel so that the clamping assembly slides within the movable opening, separating the steel from the movable basket. The operator then removes the steel. During the heating process, the steel is in a rotating state, ensuring uniform heating. The multiple partition columns help reduce the probability of the steel bending and improve the quality of the finished steel product.
[0008] Optionally, the rotating assembly includes a first driving member and several rollers. The several rollers are rotatably connected inside the movable basket and are arranged along the length of the movable basket. The several rollers are arranged in an arc shape. The first driving member is located inside the movable basket and below the rollers. The first driving member is used to drive the rollers to rotate.
[0009] By adopting the above technical solution, the moving basket and rollers work together to support the steel. During the heating process of the steel, the first driving component drives all the rollers to rotate, thereby causing the steel to rotate and improving the uniformity of the steel's heating.
[0010] Optionally, a sealing plate is vertically slidably connected to the side of the heating box near the moving basket. The sealing plate seals the heating box. A lifting component is provided at the upper end of the heating box. The lifting component is connected to the sealing plate and drives the sealing plate to move up and down vertically.
[0011] By adopting the above technical solution, when the steel enters the heating box, the lifting component drives the sealing plate to descend and seal the heating box, which helps to reduce heat loss inside the heating box.
[0012] Optionally, the clamping assembly includes a movable block, two clamping plates, two first guide rods, a movable rod, a first spring, two guide plates, and two second springs. The movable block is located within the movable opening and is slidably connected to the movable plate along the length of the movable opening. A movable groove is vertically formed at the lower end of the movable block. The two clamping plates are slidably connected to the lower end of the movable block and are located on both sides of the movable block along its width. The movable rod is located within the movable groove and is slidably connected to the movable block vertically. The first spring is located between the movable rod and the movable block. In its natural state, the first spring pushes the movable rod downward, and the lower end of the movable rod is lower than the upper surface of the clamping plate. The first guide rods correspond one-to-one with the clamping plates. One end of the first guide rod is hinged to the moving rod, and the other end of the first guide rod is hinged to the clamping plate. When the moving rod moves upward, the two first guide rods cooperate to drive the two clamping plates to move closer to each other. The moving block has two locking slots that are connected to the moving slot. The two locking slots are located on both sides of the moving block along the width direction. The guide plate corresponds to the locking slot one by one. The guide plate is located in the locking slot and is slidably connected to the moving block along the length direction of the locking slot. The second spring corresponds to the guide plate one by one. The second spring is located in the locking slot. In the natural state, the second spring pushes the guide plate closer to the moving rod. The lower end of the guide plate is inclined from bottom to top along the direction of the guide plate pointing to the moving rod.
[0013] By adopting the above technical solution, the moving block supports the clamping plate. When the steel is quenched, the hydraulic cylinder drives the moving plate to descend. During the descent of the moving plate, the moving rod first contacts the steel. The moving rod slides in the moving groove and compresses the first spring. During the movement of the moving rod, the moving rod and the first guide rod cooperate to drive the two clamping plates to move closer to each other and clamp the steel. During the movement of the moving rod, the moving rod contacts the guide plate and pushes the guide plate to slide into the snap-fit groove, compressing the second spring. When the clamping plate is in close contact with the steel, the upper end of the moving rod is above the guide plate. The second spring resets and drives the guide plate to move towards the moving rod. The upper end of the guide plate abuts against the moving rod, and the guide plate restricts the moving rod, improving the convenience of steel clamping.
[0014] Optionally, a sliding block is provided on one side of the upper end of the movable plate along the width direction. The sliding block is fixedly connected to several movable blocks. The sliding block is slidably connected to the movable plate along the width direction. A second driving member is provided on the movable plate. The second driving member drives the sliding block to slide. A reset groove connected to the moving groove is opened on the side of the movable block away from the sliding block. Several push rods are fixedly provided at the lower end of the support plate. The push rods are arranged along the length direction of the support plate. The push rods are located on the side of the movable plate away from the sliding block. The push rods correspond one-to-one with the movable blocks and are directly opposite the moving opening. A reset member is provided in the reset groove. The reset member is connected to two guide plates. When the push rod contacts the reset member, the two guide plates separate from the moving rod. A feeding plate is provided on the side of the slide rail assembly away from the sliding block. The feeding plate is inclined from top to bottom along the direction of the slide rail assembly pointing to the feeding plate. The feeding plate is located at the end of the slide rail assembly near the quenching assembly. Several baffles are fixedly provided at the upper end of the feeding plate. The baffles cooperate to form a feeding space corresponding to the storage space.
[0015] By adopting the above technical solution, after the clamping plate clamps the steel, the hydraulic cylinder drives the moving plate and the steel to move upward, so that the steel is above the moving basket. At this time, the second driving component and the sliding block cooperate to drive all the moving blocks to slide in the moving opening, so that the steel is above the feeding plate. At this time, the steel is between the two baffles. The push rod and the reset component cooperate to make the two guide plates move away from each other, thereby separating the guide plates from the moving rod. The first spring reset drives the moving rod to move downward. The moving rod and the first guide rod cooperate to make the two clamping plates move away from each other, so that the steel slides off the upper surface of the feeding plate. The cooperation of multiple baffles helps to reduce the probability of the steel tipping over and improves the convenience of steel recycling.
[0016] Optionally, the reset component includes two second guide rods and a pressing block. The pressing block is located in the reset groove and is slidably connected to the moving block along the length of the moving block. The second guide rods correspond one-to-one with the guide plates. One end of the second guide rod is hinged to the pressing block, and the other end of the second guide rod is hinged to the guide plate. When the pressing block approaches the moving rod, the second guide rod drives the guide plate to move into the snap-fit groove.
[0017] By adopting the above technical solution, when the moving block moves towards the lower material plate and the steel is above the material plate, the push rod pushes the extrusion block, causing the extrusion block to slide in the reset groove and move closer to the moving rod. The moving rod and the second guide rod cooperate to move the two guide plates away from each other, thus separating the guide plates from the moving rod. The moving rod and the first guide rod move downward to move the two clamping plates away from each other, thereby releasing the clamping plates from the steel and improving the convenience of separating the steel from the clamping plates.
[0018] Optionally, a feeding plate is provided on the side of the slide rail assembly away from the unloading plate. The feeding plate is inclined from bottom to top along the direction of the feeding plate pointing towards the slide rail assembly. The feeding plate is located at the end of the slide rail assembly near the heating box. Several connecting plates are fixedly provided at the upper end of the feeding plate. The connecting plates form a feeding space corresponding to the storage space. Several rollers are rotatably connected to the side of the connecting plates that are close to each other. The rollers are made of rubber material and are arranged along the length of the connecting plates. A controller is provided on the side of the slide rail assembly near the feeding plate. The controller is used to control the rotation of all the rollers.
[0019] By adopting the above technical solution, when steel needs to be placed inside the mobile basket, the operator pushes the steel so that it is positioned between multiple rollers. The connecting plate supports the multiple rollers, and the controller drives all the rollers to rotate, causing the steel to slide and lift on the surface of the loading plate, ultimately placing the steel inside the mobile basket, thus improving the convenience of steel placement and installation.
[0020] Secondly, this application provides a heat treatment process for round plate products, comprising the following steps: S1: The controller controls the rotation of the rollers, and several rollers drive the steel to slide on the surface of the loading plate and be located inside the moving basket. The dividing columns separate the steel. S2: The slide rail assembly moves the moving basket into the heating chamber, where the heater heats the steel. S3: The rotating component drives the steel to rotate, and the partition column restricts the deformation of the steel; S4: After the heat treatment is completed, the slide rail assembly drives the moving basket to move into the quenching assembly, and the steel is quenched inside the quenching assembly. S5: After quenching, the slide rail assembly drives the moving basket to move downward to the material plate; S6: The moving plate descends, the clamping assembly clamps the steel, and the hydraulic cylinder drives the moving plate and the steel to move upward; S7: The second driving component and the sliding block work together to move the moving block, so that the steel is positioned above the feed plate; S8: The reset component releases the clamping assembly from fixing the steel, and the steel moves along the feed plate and is recycled.
[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. The lower end of the steel is located inside the movable basket. The movable basket and the dividing columns work together to separate and limit the steel. The slide rail assembly drives the movable basket into the heating chamber. The heater heats the steel. The quenching assembly quenches the heated steel. The rotating assembly rotates all the steel. After heating, the slide rail assembly moves the movable basket out of the quenching assembly. The guide column and the support plate work together to support the hydraulic cylinder. The hydraulic cylinder drives the moving plate to descend. When the moving plate contacts the steel, the clamping assembly clamps the steel. The hydraulic cylinder and the moving plate work together to lift the clamping assembly and the steel. The operator moves the steel so that the clamping assembly slides in the moving opening to separate the steel from the movable basket. The operator then removes the steel. During the heating process, the steel is in a rotating state, which makes the steel heated evenly. The multiple dividing columns help reduce the probability of the steel bending and improve the quality of the finished steel product. 2. The moving block supports the clamping plate. When the steel is quenched, the hydraulic cylinder drives the moving plate to descend. During the descent, the moving rod first contacts the steel. The moving rod slides in the moving groove and compresses the first spring. During the movement of the moving rod, the moving rod and the first guide rod work together to bring the two clamping plates closer together and clamp the steel. During the movement of the moving rod, the moving rod contacts the guide plate and pushes the guide plate to slide into the snap-fit groove, compressing the second spring. When the clamping plate is in close contact with the steel, the upper end of the moving rod is above the guide plate. The second spring returns to its original position and drives the guide plate to move towards the moving rod. The upper end of the guide plate abuts against the moving rod, and the guide plate restricts the moving rod, improving the convenience of clamping the steel. 3. After the clamping plate clamps the steel, the hydraulic cylinder drives the moving plate and the steel to move upward, so that the steel is above the moving basket. At this time, the second driving component and the sliding block cooperate to drive all the moving blocks to slide in the moving opening, so that the steel is above the feeding plate. At this time, the steel is between the two baffles. The push rod pushes the extrusion block, so that the extrusion block slides in the reset groove and moves closer to the moving rod. The moving rod and the second guide rod cooperate to make the two guide plates move away from each other, so that the guide plates are separated from the moving rod. The moving rod and the first guide rod move downward to make the two clamping plates move away from each other, thereby releasing the clamping plate from the steel and allowing the steel to slide off the upper surface of the feeding plate. The cooperation of multiple baffles helps to reduce the probability of the steel tipping over and improves the convenience of steel recycling. Attached Figure Description
