Description

Technical Field

[0001] The present application relates to the technical field of heat treatment equipment, and in particular to heat treatment equipment for stainless steel and heat-resistant steel forgings. Background Art

[0002] Heat treatment refers to a metal thermal processing process in which the material is heated, kept warm and cooled in a solid state to obtain the expected structure and properties. As a heat-resistant material, the heating conditions during heat treatment of stainless steel heat-resistant steel forgings are crucial to the performance of the forgings.

[0003] When traditional heat treatment equipment heats stainless steel and heat-resistant steel forgings, the metal forgings to be heat treated are usually placed in a heating furnace for heating. However, in actual production, in order to save time and improve processing efficiency to the maximum extent, workers often fill the heating furnace with forgings so that the number of forgings processed at one time is close to the maximum capacity of the heating furnace.

[0004] Regarding the related technologies mentioned above, when a large number of forgings are piled up in a heating furnace, there is a problem of large differences in the heating of the forgings. The forgings close to the heating elements heat up faster, while the forgings far away from the heating elements heat up slower, resulting in inconsistent structure and performance of the forgings after heat treatment. Utility Model Content

[0005] In order to ensure that stainless steel and heat-resistant steel forgings are heated evenly during heat treatment, thereby ensuring that the structure and performance of the forgings after heat treatment are consistent, the present application provides a heat treatment device for stainless steel and heat-resistant steel forgings.

[0006] This application provides a heat treatment equipment for stainless steel heat-resistant steel forgings, which adopts the following technical solutions:

[0007] A heat treatment equipment for stainless steel and heat-resistant steel forgings, comprising:

[0008] A furnace body, wherein one side of the furnace body is an open structure;

[0009] A furnace door, the furnace door being slidably disposed at the furnace body opening;

[0010] Layered plates, the number of which is not less than two, are arranged in the furnace body and are used to lay stainless steel and heat-resistant steel forgings in layers;

[0011] The heating wire is arranged in the furnace body and is used to heat the stainless steel and heat-resistant steel forgings.

[0012] By adopting the above technical solution, the layered plates divide the interior of the furnace into multiple spaces. The heating wires are distributed not only on the inner wall of the furnace body, but also on the layered plates, heating the forgings from multiple directions. The stainless steel and heat-resistant steel forgings are laid flat on the layered plates, avoiding the problem of uneven heat transfer caused by the accumulation of forgings in traditional equipment, so that the stainless steel and heat-resistant steel forgings are heated evenly during heat treatment, thereby improving the quality of the forgings.

[0013] Optionally, a transport assembly is installed on a side of the furnace body close to the furnace door, and the transport assembly includes:

[0014] Mounting rack;

[0015] Conveying rollers, the number of which is no less than two, the conveying rollers being arranged in parallel, and the conveying rollers being rotatably mounted on the mounting frame;

[0016] A motor, wherein a fixed end of the motor is fixedly mounted on the mounting frame;

[0017] Sprockets, the number of the sprockets corresponding to the number of the conveying rollers is one-to-one, the sprockets are fixedly mounted on one end of the conveying roller, and one of the sprockets is coaxially fixedly connected to the output end of the motor;

[0018] A chain is wound around the sprocket.

[0019] By adopting the above technical solution, the motor drives the conveyor roller to rotate through the sprocket and chain, thereby automatically transporting the stainless steel and heat-resistant steel forgings produced in the previous process into the furnace body. Operators do not need to manually carry the forgings, which greatly reduces labor intensity and improves work efficiency.

[0020] Optionally, a slide groove is provided on the mounting frame, and a lifting assembly is installed on the transport assembly, and the lifting assembly includes:

[0021] A support frame, wherein the bottom of the support frame is fixedly mounted on the ground, and the top of the support frame is hinged to the mounting frame;

[0022] A slider, the slider being slidably mounted in the slide groove;

[0023] A lifting cylinder, wherein the movable end of the lifting cylinder is hinged on the slider, and the fixed end of the lifting cylinder is fixedly installed on the ground.

[0024] By adopting this technical solution, the lifting cylinder can adjust the height of the transport assembly. When stainless steel and heat-resistant steel forgings need to be fed into the heat treatment furnace, the lifting cylinder can be adjusted to drive the slider to slide within the chute, so that the transport assembly matches the height of the different layer plates in the furnace, facilitating the smooth placement of forgings from the conveyor rollers onto the layer plates. During discharge, the lifting cylinder can also be used to adjust the mounting frame to the appropriate height, facilitating the removal and transfer of forgings.

[0025] Optionally, a groove is provided on the inner wall of the furnace body away from the furnace door, and the number of the grooves corresponds one-to-one to the number of the layered plates. A lifting cylinder is provided in the groove, and the movable end of the lifting cylinder abuts against the layered plate, and the fixed end of the lifting cylinder is fixedly installed on the furnace body.

[0026] By adopting the above technical solution, the setting of the lifting cylinder allows the angle of the layer plate to be adjusted as needed. When placing stainless steel and heat-resistant steel forgings, the layer plate can be adjusted to a suitable inclination angle so that the forgings can smoothly enter the furnace body and be laid flat on the layer plate. When the forgings are heated and taken out of the furnace body, the inclination angle of the layer plate can also be increased by the lifting cylinder, so that the heated forgings can be quickly moved out of the furnace body, thereby improving the transportation efficiency of the forgings.

[0027] Optionally, a vacuum pump is provided at the top of the furnace body.

[0028] By adopting the above technical solution, the vacuum device can extract the air in the furnace body to create a near-vacuum environment. During the heating process of stainless steel and heat-resistant steel forgings, it can effectively prevent the forgings from coming into contact with oxygen in the air, avoid the occurrence of oxidation reactions, and thus ensure that the forgings maintain a good surface condition during the heat treatment process.

[0029] Optionally, a controller is fixedly mounted on the furnace body, a temperature sensor is fixedly mounted in the furnace body, and the temperature sensor and the heating wire are electrically connected to the controller.

[0030] By adopting the above technical solution, the temperature sensor can monitor the temperature changes in the furnace body in real time and transmit the temperature data to the controller. The controller accurately controls the heating power of the heating wire based on the information fed back by the temperature sensor. For different stainless steel and heat-resistant steel forgings and heat treatment requirements, the controller can adjust process parameters such as heating temperature and time, so that it can adapt to different production needs, thereby improving the versatility and flexibility of heat treatment and the stability of heat treatment quality.

[0031] Optionally, the motor, the lifting cylinder and the lifting cylinder are all electrically connected to the controller.

[0032] By adopting the above technical solution, the controller can centrally control the motor, lifting cylinder and lifting cylinder, and the operator can operate conveniently through the controller. During the feeding process, the controller starts the motor to transport the forgings into the furnace, and at the same time controls the lifting cylinder to adjust the height of the mounting frame so that the forgings enter the furnace body and align with the layer plate, and then controls the lifting cylinder to adjust the inclination angle of the layer plate so that the forgings can be laid flat on the layer plate for heating treatment. The discharging process can also be automatically adjusted by the controller, which improves the convenience and efficiency of feeding and discharging.

[0033] Optionally, a heat preservation plate is fixedly mounted on the outer wall of the furnace body.

[0034] By adopting the above technical solution, the insulation board is fixedly installed on the outer wall of the furnace body, which can effectively prevent the heat in the furnace from being lost to the external environment, reduce the temperature difference between the outer wall of the furnace body and the internal space of the furnace body, and make the heat more evenly distributed in the furnace. The presence of the insulation board greatly reduces the conduction and loss of heat, thereby reducing energy consumption.

[0035] In summary, this application includes at least one of the following beneficial technical effects:

[0036] 1. By setting up layered plates, the interior of the furnace is divided into multiple spaces, allowing the heating wire to heat the forgings from multiple directions, avoiding the problem of uneven heat transfer caused by forging accumulation in traditional equipment;

[0037] 2. By setting up a transport component, the stainless steel and heat-resistant steel forgings produced in the previous process are automatically transported to the furnace body. Operators do not need to manually carry the forgings, which greatly reduces labor intensity and improves work efficiency;

[0038] 3. By setting up the lifting cylinder, the height of the transport assembly can be adjusted to match the height of the different layer plates in the furnace body, making it convenient for forgings to be smoothly laid from the conveyor roller to the layer plate.

[0046] The following is combined with Figure 1-2 This application is described in further detail.

[0047] The embodiment of the present application discloses a heat treatment device for stainless steel and heat-resistant steel forgings.

[0048] Reference Figure 1 and Figure 2 The heat treatment equipment for stainless steel heat-resistant steel forgings includes a furnace body 1, a furnace door 2, a layering plate 3, and an electric heating wire 4. The furnace body 1 has an open structure on one side, and the furnace door 2 is slidably arranged at the opening of the furnace body 1. The number of the layering plates 3 is not less than two, and the layering plates 3 are arranged in the furnace body 1. The layering plates 3 are used to lay the stainless steel heat-resistant steel forgings in layers. The electric heating wire 4 is arranged in the furnace body 1 and is also arranged on the layering plates 3 and the furnace door 2. The electric heating wire 4 is used to heat the stainless steel heat-resistant steel forgings.

[0049] When in use, the furnace door 2 is slid open to one side to expose the internal space of the furnace body 1, and the stainless steel heat-resistant steel forgings to be heated are layered and laid flat on the layering plate 3 in the furnace body 1. After the forgings are placed, the furnace door 2 is slid closed and the heating wires 4 are started. The heating wires 4 set in various places in the furnace body 1 begin to release heat, heating the stainless steel heat-resistant steel forgings in the furnace body 1 from multiple directions, so that the forgings are heated evenly during heat treatment, thereby improving the quality of the forgings.

[0050] Reference Figure 1 and Figure 2 A transport assembly 5 is mounted on the side of the furnace body 1 near the furnace door 2. The transport assembly 5 includes a mounting frame 51, a conveyor roller 52, a motor 53, a sprocket 54, and a chain 55. The conveyor rollers 52 are cylindrical and horizontally arranged, with the axes of the multiple conveyor rollers 52 arranged parallel to each other. The conveyor rollers 52 are all rotatably mounted on the mounting frame 51. The fixed end of the motor 53 is fixedly mounted on the mounting frame 51. The number of sprockets 54 corresponds to the number of conveyor rollers 52. The sprockets 54 are fixedly mounted on one end of the conveyor rollers 52. One of the sprockets 54 is coaxially fixedly connected to the output end of the motor 53. The chain 55 is wound around the sprockets 54. The conveying direction of the transport assembly 5 is perpendicular to the axis of the conveyor rollers 52.

[0051] When in use, the motor 53 is started, and the motor 53 drives the sprocket 54 fixed to it to rotate, and the sprocket 54 drives the chain 55 to move, and the chain 55 drives other sprockets 54 wound around it to rotate synchronously, thereby driving all the conveyor rollers 52 to start rotating, and the stainless steel heat-resistant steel forgings produced in the previous process are placed on the conveyor rollers 52. The rotation of the conveyor rollers 52 makes the forgings move on the surface of the conveyor rollers 52, and the forgings are smoothly transported from the outside of the furnace body 1 to the opening of the furnace body 1 and into the inside of the furnace body 1. If the motor 53 is reversed, the forgings that have completed the heat treatment and are removed from the furnace body 1 can be transported from the furnace body 1 to the next production process. The operator does not need to manually carry the forgings, which improves work efficiency.

[0052] Reference Figure 1 and Figure 2 The mounting frame 51 is provided with a chute 511, the length of which is consistent with the transport direction of the transport assembly 5. The transport assembly 5 is provided with a lifting assembly 6, which includes a support frame 61, a slider 62, and a lifting cylinder 63. The support frame 61 is a rectangular column and is vertically arranged. The bottom of the support frame 61 is fixedly mounted on the ground, and the top of the support frame 61 is hinged to the mounting frame 51. The slider 62 is slidably mounted in the chute 511, and the sliding direction is consistent with the transport direction of the transport assembly 5. The lifting cylinder 63 is vertically arranged, and the movable end of the lifting cylinder 63 is hinged to the slider 62, and the fixed end of the lifting cylinder 63 is fixedly mounted on the ground.

[0053] When in use, the lifting cylinder 63 is connected to the air source. When the transport component 5 needs to transport forgings to the upper layer plate 3, air is inflated into the lifting cylinder 63 to extend the movable end of the lifting cylinder 63, pushing the slider 62 to slide in the slide groove 511, and at the same time driving the mounting frame 51 to rise. When the transport component 5 needs to transport forgings to the lower layer plate 3, the air source is controlled to discharge the gas in the lifting cylinder 63, the movable end of the lifting cylinder 63 is retracted, and the height of the conveying roller 52 is lowered to adapt to the transportation requirements of different heights. When discharging, the conveying roller 52 can also be adjusted to a suitable height through the lifting cylinder 63, so that the forgings can be smoothly laid from the conveying roller 52 to the layer plate 3.

[0054] Reference Figure 1 and Figure 2 A groove 7 is provided on the inner wall of the furnace body 1 away from the furnace door 2. The number of grooves 7 corresponds to the number of layer plates 3. A lifting cylinder 8 is provided in the groove 7. The lifting cylinder 8 is vertically arranged. The movable end of the lifting cylinder 8 abuts against the layer plate 3, and the fixed end of the lifting cylinder 8 is fixedly installed on the furnace body 1.

[0055] When in use, the lifting cylinder 8 is connected to the gas source. Before loading, the lifting cylinder 8 is in a retracted state and the layer plate 3 is in a slightly tilted state toward the furnace, so that the forgings can roll from the transport assembly 5 into the furnace body 1 and be laid flat on the layer plate 3, so that the forgings are heated evenly. When the heat treatment is completed and the forgings need to be taken out of the furnace body 1, the movable end of the lifting cylinder 8 is extended to lift the layer plate 3, so that the forgings are moved out of the furnace body 1 and moved to the moving assembly, thereby improving the transportation efficiency of the forgings.

[0056] Reference Figure 1 and Figure 2 A controller 11 is fixedly installed on the furnace body 1, and a temperature sensor 10 is fixedly installed inside the furnace body 1. The temperature sensor 10 and the heating wire 4 are electrically connected to the controller 11. At the same time, the motor 53, the lifting cylinder 63 and the lifting cylinder 8 are also electrically connected to the controller 11.

[0057] When in use, the temperature sensor 10 monitors the temperature in the furnace in real time and transmits the temperature data to the controller 11. The controller 11 automatically adjusts the heating power of the heating wire 4 according to the heating temperature required by the forging and the actual temperature feedback from the temperature sensor 10, so as to keep the temperature in the furnace stable within the required temperature range. During the loading and unloading process, the controller 11 can control the operating state of the transport component 5 to start the conveying roller 52. At the same time, the controller 11 controls the lifting cylinder 63 to adjust the height of the mounting frame 51 so that the conveying roller 52 is aligned with the layered plate 3 in the furnace body 1 to achieve smooth loading and unloading. The controller 11 also controls the lifting cylinder 8 so that the forging can be conveyed to the deep part of the furnace body 1 and laid on the layered plate 3, and ensures that the forging is smoothly moved to the transmission component during the unloading process. Automatic adjustment is achieved through the controller 11, which improves the convenience and efficiency of loading and unloading.

[0058] Reference Figure 1 and Figure 2 A vacuum pump 9 is provided at the top of the furnace body 1. After the forgings to be heat treated are placed on the layered plate 3 in the furnace body 1, the furnace door 2 is closed to ensure that the furnace door 2 is well sealed. The vacuum pump 9 is started to extract the air in the furnace body 1 to create a near-vacuum environment to avoid oxidation reactions in the forgings during the heat treatment process, which may affect the heat treatment quality of the forgings.

[0059] Reference Figure 1 An insulation board 12 is fixedly mounted on the outer wall of the furnace body 1, which can effectively prevent the heat in the furnace from being lost to the external environment, thereby reducing energy consumption.

[0060] The implementation principle of the heat treatment equipment for stainless steel heat-resistant steel forgings in an embodiment of the present application is as follows: when performing heat treatment on stainless steel heat-resistant steel forgings, the forging to be treated is first placed on the conveying roller 52 of the transport assembly 5, and the motor 53 drives the conveying roller 52 to rotate through the sprocket 54 and the chain 55 to transport the forging to the vicinity of the furnace body 1, and the height of the mounting frame 51 is adjusted by the lifting cylinder 63 to align the forging with the layering plate 3 inside the furnace body 1, so as to facilitate the forging to enter the furnace body 1.

[0061] The angle of the layered plate 3 can be adjusted by the lifting cylinder 8 so that the forgings can enter the furnace body 1 and be evenly laid out, optimizing the heat distribution during heating. The heating wires 4 are distributed on the inner wall of the furnace body 1, the layered plate 3 and the furnace door 2 to heat the forgings. The temperature sensor 10 monitors the temperature in the furnace in real time and transmits the data to the controller 11. The controller 11 automatically adjusts the heating power of the heating wires 4 according to the required temperature to ensure that the temperature in the furnace is stable within the required range.

[0062] The vacuum pump 9 at the top of the furnace body 1 extracts air from the furnace, creating an oxygen-free environment, preventing oxidation of the forgings and improving the quality of the heat treatment. Simultaneously, the insulation board 12 on the outer wall of the furnace body 1 reduces heat loss, saves energy, stabilizes the furnace temperature, protects the equipment and operators, and improves equipment efficiency.

[0063] During the heating treatment process of the forging, the controller 11 centrally controls the motor 53, the lifting cylinder 63, the lifting cylinder 8 and the vacuum pump 9 to realize automated operation, and the forging is more evenly distributed in the furnace body 1, so that the forging is heated evenly during the heat treatment, thereby making the structure and performance of the forging consistent after heat treatment.

[0064] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
