Description

Technical Field

[0001] This utility model relates to the field of electromagnetic induction heating technology, and in particular to a medium-frequency induction heating device for metal heat treatment. Background Technology

[0002] Metal heat treatment is a process that alters the physical and mechanical properties of metal materials by heating and cooling them. This treatment can improve the hardness, strength, toughness, and wear resistance of metals to meet the needs of various industrial applications. Medium-frequency induction heating equipment can generate eddy currents inside the metal through the principle of electromagnetic induction, causing the metal to heat up itself. This method has advantages such as fast heating speed, high efficiency, and precise temperature control, making it particularly suitable for the modern industrial demand for efficient and precise heating. Using medium-frequency induction heating equipment for heat treatment can achieve localized heating, reduce the heat-affected zone, and avoid overall metal deformation. In addition, the cleanliness and environmental friendliness of induction heating also make it more advantageous in heat treatment, as it does not produce open flames or exhaust gases, reducing environmental pollution.

[0003] This invention relates to a utility model patent with publication number CN214799947U, which discloses a medium-frequency induction heating device for metal heat treatment. The device includes a base, with two fixed plates fixedly mounted on the top of the base near the left side. Two rollers are movably mounted between the two fixed plates near the top. A conveyor belt is movably mounted on the outer side of the rollers. A first motor is fixedly mounted on the right side of the rear fixed plate, with one end of the first motor fixedly connected to the right-side roller. This medium-frequency induction heating device for metal heat treatment utilizes two fixed plates fixed to the top of the base, two movably mounted rollers between the two fixed plates, a first motor fixed to one end of the right-side roller, and a conveyor belt movably mounted on the outer side of the roller. When a workpiece is placed on the conveyor belt, activating the first motor causes the conveyor belt to rotate, thereby moving the workpiece to the right into the heating chamber, achieving automatic feeding.

[0004] However, this patent uses a conveyor belt for feeding, which requires placing the workpiece between two limiting plates. The width between the two limiting plates is limited, which has certain limitations in practical use. Utility Model Content

[0021] To make the technical means, creative features, objectives and effects of the embodiments of this application easier to understand, the embodiments of this application are further described below in conjunction with the figures and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the embodiments of this application and are not intended to limit the embodiments of this application.

[0022] Figure 1This schematically illustrates a medium-frequency induction heating device for metal heat treatment according to the present invention, comprising a base plate 1, a fixing plate 12 integrally formed with the bottom end of the base plate 1, a sliding groove 13 formed on the top of the base plate 1, a push plate 14 slidably mounted in the sliding groove 13, a driving device 2 below the push plate 14 capable of pushing the push plate 14 to slide in the sliding groove 13, a heating chamber 15 fixedly connected to one end of the base plate 1, a fixing device 3 provided in the heating chamber 15, an electromagnetic induction heating cylinder 16 below the fixing device 3, the electromagnetic induction heating cylinder 16 being rotatably mounted in the heating chamber 15, a first motor 17 fixedly connected to one end of the electromagnetic induction heating cylinder 16 passing through the heating chamber 15, and the bottom end of the first motor 17 being fixedly connected to... A placement plate 18 is attached, with one end of the placement plate 18 fixedly connected to the outer wall of the heating chamber 15. A reinforcing rod 4 is provided below the placement plate 18, with one end of the reinforcing rod 4 fixedly connected to the bottom of the placement plate 18 and the other end fixedly connected to the heating chamber 15. The reinforcing rod 4 can form a triangle between the placement plate 18 and the heating chamber 15, thereby improving the strength of the placement plate 18. Both ends of the fixing plate 12 are provided with mounting blocks 5 integrally formed with the fixing plate 12. Mounting holes 51 are opened in the middle of the mounting blocks 5. The equipment can be fixedly installed by setting bolts or other fixing tools in the mounting holes 51. The sharp parts of the bottom plate 1 are all provided with rounded corners 6. The rounded corners 6 can effectively reduce the damage caused by bumps and collisions and can also prevent scratches during use.

[0023] like Figure 2 and Figure 3 The drive device 2 shown includes a second motor 21, which is fixedly installed inside the base plate 1. The output end of the second motor 21 passes through the base plate 1 and is fixedly connected to a turntable 22. The surface of the turntable 22 has an irregularly shaped column 23. The bottom end of the irregularly shaped column 23 is rotatably connected to a fixed column 24. One end of the fixed column 24 is fixedly connected to the base plate 1. An irregularly shaped groove 25 is opened in the irregularly shaped column 23. A drive column 26 is slidably connected in the irregularly shaped groove 25. One end of the drive column 26 is fixedly connected to the turntable 22. A transmission block 27 is rotatably connected to the top of the irregularly shaped column 23. A connecting block 28 is rotatably connected to the other end of the transmission block 27. A push plate 14 is fixedly connected to the top of the connecting block 28.

[0024] In practice, the workpiece to be heated is simply placed on the push plate 14, and then the second motor 21 is started. The rotation of the second motor 21 will drive the turntable 22 to rotate, and the rotation of the turntable 22 will drive the drive column 26 to move. The drive column 26 will slide in the irregular groove 25, thereby pushing the irregular column 23 to rotate around the fixed column 24. The rotation of the irregular column 23 around the fixed column 24 will drive the transmission block 27 to move, and the movement of the transmission block 27 will drive the connecting block 28 to move. The movement of the connecting block 28 will drive the push plate 14 to move, thereby sending the workpiece on the push plate 14 into the heating chamber 15.

[0025] like Figure 2 and Figure 4The fixing device 3 shown includes a storage slot 31, which is opened on the inner wall of the heating chamber 15. A pair of storage slots 31 are provided and are symmetrically arranged. A push block 32 is slidably installed in the pair of storage slots 31. A connecting post 33 is fixedly connected to one end of the push block 32. The connecting post 33 passes through the heating chamber 15. A protective sleeve 7 is provided on the end of the connecting post 33 away from the push block 32. The protective sleeve 7 can be made of a material with poor thermal conductivity, such as wood, so that the user can easily hold the connecting post 33.

[0026] In practice, when the pusher plate 14 sends the workpiece into the heating chamber 15, the workpiece will slide into the receiving groove 31 and be limited thereto. At this time, the first motor 17 is started. The rotation of the first motor 17 will drive the electromagnetic induction heating cylinder 16 to rotate. The rotation of the electromagnetic induction heating cylinder 16 will heat the workpiece in the receiving groove 31. After the workpiece is heated, the user can hold the connecting column 33 and push it. Then the pusher block 32 can push the workpiece in the receiving groove 31 to move, thereby pushing the workpiece out of the heating chamber 15 and completing the unloading.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
