Description

Technical Field

[0001] This utility model relates to the field of high-frequency furnace equipment technology, specifically a high-frequency furnace for heat treatment of shaft components. Background Technology

[0002] A high-frequency furnace is an industrial device that uses the principle of electromagnetic induction to convert electrical energy into heat energy to heat metal workpieces. It is named for its high-frequency operating frequency, which is usually between 10kHz and 400kHz (some can be higher). It is widely used in industrial applications such as metal heat treatment, smelting, and welding.

[0003] When a metal workpiece is placed inside an induction coil, the alternating magnetic field passes through the workpiece, inducing countless closed eddy currents inside the workpiece (similar to the circular current formed by current in a conductor). When the eddy currents flow inside the workpiece, they are hindered by the metal's own resistance. According to Joule's law, the resistance will convert electrical energy into heat energy, causing the workpiece to heat up rapidly. Electrical energy is directly converted into the workpiece's own heat energy, resulting in minimal heat loss.

[0004] In the existing process of heat treatment of shaft components using a high-frequency furnace, if the metal workpiece is not cleaned before heating, or if there are residual oil stains, rust-preventive oil, release agents, paint coatings, packaging films, and other organic substances on the surface, these substances will decompose and volatilize under the high temperature of high-frequency heating, thereby producing fumes, volatile organic compounds (VOCs), and other volatile substances. These volatile substances will directly lead to a decline in the air quality in the workshop, accompanied by obvious odors. This not only damages the cleanliness of the working environment, but may also affect the working comfort of the operators, and have an adverse impact on the overall environment of the workshop.

This allows the device to be used with workpiece bodies 13 of different lengths within a certain range, improving the utilization rate and practicality of the device.

[0031] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-3 The adsorption component 12 and the limiting rod 9 are connected by bolts, and a purification device is provided at the end of the limiting rod 9 away from the workpiece body 13 to further treat the odor and reduce the harm of the odor to the workers.

[0032] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-3 The adsorption component 12 is L-shaped and is positioned opposite to the workpiece body 13. The adsorption component 12 specifically adsorbs the surrounding area of ​​the workpiece body 13, thereby improving the working efficiency of the adsorption component 12.

[0033] For details regarding the above embodiments, please refer to [link / reference].
