Description

Technical Field

[0001] The utility model relates to the technical field of high-frequency induction furnaces, in particular to a high-frequency induction furnace for metal surface heat treatment. Background Art

[0002] High-frequency induction furnace uses the principle of electromagnetic induction to heat and melt metal. This method is an ideal heating process and has been widely used in metal smelting, welding, surface quenching and other processing and heat treatment processes. The working principle of high-frequency induction furnace is that a high-frequency high-frequency current flows to the heating coil wound into a ring or other shape, thereby generating a strong magnetic flux with instantaneous polarity changes in the coil. When the heated object such as metal is placed in the coil, the magnetic flux will penetrate the entire heated object, and a corresponding large eddy current will be generated in the opposite direction of the heating current inside the heated object. Due to the existence of resistance in the heated object, a lot of Joule heat will be generated, causing the temperature of the object itself to rise rapidly, thereby achieving the purpose of heating the metal material;

[0003] When a high-frequency induction furnace is used, the metal blank needs to be placed inside the coil. This operation is mostly done by humans to position the metal blank, which is inconvenient during processing. Therefore, it needs to be improved to make it easier to use. Utility Model Content

[0004] The utility model aims to provide a high-frequency induction furnace for metal surface heat treatment, so as to solve the problem in the above background technology that it is inconvenient to place the metal blank inside the furnace body.

[0013] Compared with the prior art, the utility model has the following beneficial effects: by providing the ejector pin and the four-claw chuck, the four-claw chuck can be used alone to clamp the metal blank. If the metal blank is too long, the stability is poor if it is clamped by the four-claw chuck alone. At this time, the ejector pin can be rotated, and the ejector pin cooperates with the adjusting table thread to move toward the four-claw chuck side and push against the tail end of the blank, thereby realizing the convenience of fixing the blank of the high-frequency induction furnace.

[0014] By providing a smoke exhaust hole and a metal hose, the smoke exhaust hole is connected with the tail hole and the front hole, and the metal hose on the top can be connected to the air treatment equipment. The gas generated during the heat treatment inside the induction furnace body can be introduced into the air treatment equipment through the smoke exhaust hole and the metal hose, and discharged after being treated, thereby reducing the pollution caused by the gas to the surroundings and reducing the pollution of the high-frequency induction furnace when in use;

[0015] An electric push rod is provided, and the connecting platform is located at the front end of the electric push rod. The screw hole on the surface of the connecting platform is threadedly connected with a bolt. After the bolt is turned to insert the plug rod on the top into the socket on the bottom side of the workbench, the connection between the electric push rod and the bottom side of the workbench can be completed. As the electric push rod is extended and retracted, the workbench can be driven to move left and right, thereby realizing the convenience of using the high-frequency induction furnace.
