Description

Technical Field

[0001] This utility model relates to the field of quenching equipment technology, specifically a quenching furnace with adjustable function. Background Technology

[0002] In the field of metal processing, quenching is an important heat treatment process for improving the properties of metallic materials. By heating a metal workpiece to a specific temperature and then rapidly cooling it, the microstructure of the metal can be effectively altered, significantly improving its hardness, strength, and wear resistance. It is widely used in industries such as machinery manufacturing, automobile manufacturing, and aerospace. The quenching furnace, as a key piece of equipment in the quenching process, plays a decisive role in the quenching quality due to its heating effect.

[0003] Traditional quenching furnaces typically have a fixed distance between the heating element and the workpiece, making it difficult to adapt to the heating requirements of workpieces with different shapes, sizes, and materials. This results in uneven heating and affects the quenching effect. Therefore, a quenching furnace with adjustable function is proposed to solve the above-mentioned problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a quenching furnace with an adjustable function, which addresses the shortcomings of the prior art.

[0005] To solve the above technical problems, the technical solution adopted by this utility model is: a quenching furnace with an adjustable function, including a furnace body, a rotating column rotatably connected to the bottom inner wall of the furnace body through a bearing, a placement plate fixedly connected to the top of the rotating column, and a heating adjustment mechanism provided on the furnace body;

[0006] The heating adjustment mechanism includes a frame and a rotating shaft. The frame is fixedly connected to the inner wall of the furnace body. Two sliding plates are slidably connected to the inner cavity of the frame. Mounting plates are fixedly connected to the bottom of the two sliding plates. Electric heating plates are connected to the opposite sides of the two mounting plates. A sliding rod is fixedly connected to the top of each sliding plate. The rotating shaft is rotatably connected to the top inner wall of the furnace body through bearings. A turntable is fixedly connected to the bottom of the rotating shaft. Two sliding holes are opened at the bottom of the turntable.

[0007] Preferably, both sliding holes are arc-shaped and symmetrically arranged, and the two sliding rods are slidably connected to the inner walls of the two sliding holes respectively.

[0008] Preferably, the inner wall of the frame is provided with a groove, and the two slide plates are slidably connected to the inner wall of the groove.

[0009] Preferably, a first motor is connected to the top of the furnace body, and the top end of the rotating shaft passes through the furnace body and is fixedly connected to the output end of the first motor through a coupling.

[0010] Preferably, a second motor is connected to the bottom of the furnace body, and the bottom end of the rotating column passes through the furnace body and is fixedly connected to the output end of the second motor through a coupling.

[0011] Preferably, a pressure relief valve is connected to the top of the furnace body, and support legs are fixedly connected to the four corners of the bottom of the furnace body.

[0012] Preferably, the front of the furnace body is hinged to the furnace door, and the front of the furnace door has a transparent viewing window.

[0013] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0014] 1. This quenching furnace with adjustable function drives a rotating shaft to rotate by starting a first motor. The rotating shaft drives a turntable to rotate, which in turn causes a sliding rod to slide in a sliding hole on the turntable. This causes the sliding rod to drive a sliding plate to slide within the frame. The sliding of the sliding plate causes the mounting plate and the connected electric heating plate to move closer to or further away from the workpiece placed on the shelf. This allows for precise adjustment of the distance between the electric heating plate and the workpiece according to different shapes and sizes of workpieces, ensuring that all parts of the workpiece are heated more evenly. This effectively avoids the problem of uneven heating caused by the fixed heating distance in traditional quenching furnaces and improves the quenching quality.

[0015] 2. This quenching furnace with adjustable function drives the rotating column to rotate by starting the second motor. The rotating column drives the placement plate to rotate, so that the workpiece placed on the placement plate rotates and changes position continuously during the quenching process. This ensures that all parts of the workpiece can receive heat fully and evenly, ensuring that the microstructure of the workpiece is uniform after quenching, thereby significantly improving the hardness, strength and wear resistance of the workpiece.

[0025] Please see Figure 1-4One embodiment of this utility model is as follows: a quenching furnace with an adjustable function includes a furnace body 1. A rotating column 2 is rotatably connected to the bottom inner wall of the furnace body 1 via a bearing. A placement plate 3 is fixedly connected to the top of the rotating column 2. A heating adjustment mechanism 4 is provided on the furnace body 1. The heating adjustment mechanism 4 includes a frame 41 and a rotating shaft 46. The frame 41 is fixedly connected to the inner wall of the furnace body 1. Two sliding plates 42 are slidably connected to the inner cavity of the frame 41. A sliding groove is opened on the inner wall of the frame 41. The two sliding plates 42 are slidably connected to the inner wall of the sliding groove. Mounting plates 43 are fixedly connected to the bottom of the two sliding plates 42 respectively. Electric heating plates 44 are connected to the opposite surfaces of the two mounting plates 43 respectively. A sliding rod 45 is fixedly connected to the top of each sliding plate 42. The rotating shaft 46 is rotatably connected to the top inner wall of the furnace body 1 via a bearing. A first motor 49 is connected to the top of the furnace body 1. The top of the rotating shaft 46 passes through the furnace body 1 and... The shaft 46 is fixedly connected to the output end of the first motor 49 via a coupling. A turntable 47 is fixedly connected to the bottom end of the shaft 46. Two sliding holes 48 are opened at the bottom of the turntable 47. The two sliding holes 48 are arc-shaped and symmetrically arranged. Two sliding rods 45 are slidably connected to the inner walls of the two sliding holes 48 respectively. By starting the first motor 49, the shaft 46 is driven to rotate. The shaft 46 drives the turntable 47 to rotate, which in turn causes the sliding rods 45 to slide in the sliding holes 48 on the turntable 47. This causes the sliding rods 45 to drive the slide plate 42 to slide within the frame 41. The sliding of the slide plate 42 causes the mounting plate 43 and the connected electric heating plate 44 to move closer to or further away from the workpiece placed on the placement plate 3. This allows for precise adjustment of the distance between the electric heating plate 44 and the workpiece according to different shapes and sizes of workpieces, so that all parts of the workpiece can be heated more evenly. This effectively avoids the problem of uneven heating caused by the fixed heating distance in traditional quenching furnaces and improves the quenching quality.

[0026] Working principle: The workpiece is placed on the placement plate 3, the furnace door 7 is closed, and the workpiece is heated and quenched by starting the electric heating plate 44. The first motor 49 is started to drive the rotating shaft 46 to rotate, and the rotating shaft 46 drives the turntable 47 to rotate, which in turn causes the slide rod 45 to slide in the arc-shaped sliding hole 48 on the turntable 47. This causes the slide rod 45 to drive the sliding plate 42 to slide in the frame 41. The sliding of the sliding plate 42 causes the mounting plate 43 and the connected electric heating plate 44 to move closer to or further away from the workpiece placed on the placement plate 3. This allows for precise adjustment of the distance between the electric heating plate 44 and the workpiece according to different shapes and sizes of workpieces, so that all parts of the workpiece can be heated more evenly.

[0027] Please see Figure 1-4Based on the above embodiments, in another embodiment of this utility model, a second motor 5 is connected to the bottom of the furnace body 1. The bottom end of the rotating column 2 passes through the furnace body 1 and is fixedly connected to the output end of the second motor 5 via a coupling. By starting the second motor 5, the rotating column 2 is driven to rotate, and the rotating column 2 drives the placement plate 3 to rotate, so that the workpiece placed on the placement plate 3 rotates and continuously changes position during the quenching process, so that all parts of the workpiece can receive heat fully and evenly, ensuring that the microstructure of the workpiece is uniform after quenching, thereby significantly improving the hardness, strength and wear resistance of the workpiece. A pressure relief valve 6 is connected to the top of the furnace body 1. 6. When the pressure inside the furnace is too high, it can automatically open to release pressure, avoiding safety accidents such as explosions caused by excessive pressure inside the furnace, ensuring the safe operation of the equipment and the personal safety of the operators. Support legs are fixedly connected to the four corners of the bottom of the furnace body 1. The front of the furnace body 1 is hinged to the furnace door 7. A transparent viewing window 8 is provided on the front of the furnace door 7. Through the transparent viewing window 8, the operator can easily observe the heating status of the workpiece inside the furnace at any time without opening the furnace door 7. The operator can understand the color change of the workpiece, the heating progress, etc. in a timely manner, and adjust the heating parameters according to the actual situation, improving the convenience and accuracy of operation.

[0028] Working principle: By starting the second motor 5, the rotating column 2 is driven to rotate. The rotating column 2 drives the placement plate 3 to rotate, so that the workpiece placed on the placement plate 3 rotates and changes position continuously during the quenching process, so that all parts of the workpiece can receive heat fully and evenly.

[0029] It is worth noting that the electric heating plate 44, the first motor 49, the second motor 5, and the pressure relief valve 6 in the above embodiments are all commonly used devices in the prior art. The models used can be customized according to actual usage requirements. Furthermore, the power supply interface of the electrical equipment in this utility model is connected to the power supply system through a switch (not shown in the figure) and wires (not shown in the figure) to achieve control. The circuit control, specific composition, and principle involved are all prior art and are well known in the current field. They are clear to those skilled in the art, so they will not be described in detail here.
