High-frequency quenching device for right-angle part of rotary body

Abstract

The invention provides a high-frequency quenching device for a right-angle part of a rotary body. The device comprises an induction coil, a magnetizer, a tray, a stop screw and a connecting column, wherein the tray is used for supporting a rotary body part to be processed, the connecting column is connected with the tray and an external machine tool, and the stop screw is used for fixing the tray and the connecting column; the induction coil is mounted on the external machine tool, can be connected to a high-frequency current and is coaxial with the rotary body part to be processed; the section, close to the right-angle root part of the rotary body part to be processed, of the induction coil is sharp-angle-shaped; the magnetizer is bonded with and wraps the induction coil, and only is the sharp-angle-shaped part of the induction coil exposed out of the magnetizer. According to the device, the circular coil effect of electromagnetic induction can be properly reduced, overhigh heating speed of a vertical cylindrical surface is avoided, the sharp angle effect during the electromagnetic induction can be effectively avoided, and the effect of heating the root part of the part is achieved by virtue of drive current of the magnetizer.

Description

technical field [0001] The invention relates to the technical field of heat treatment, in particular to a high-frequency quenching device for a right-angle part of a revolving body, which can meet the requirement of simultaneous heating of two vertical surfaces and roots of the right-angle part of a revolving body, and has stable processing quality. Background technique [0002] In the design process of some optoelectronic mechanical systems, in order to meet the overall requirements such as the technical indicators of the overall system, a turntable with a non-standard guide rail structure is often designed. The hollow shaft key parts used in these non-standard guide rail structure designs all have high-frequency quenching technical requirements for rotary right-angle guide rails, requiring both vertical surfaces and roots to reach high hardness (HR58~63), and the quenching surface of the guide rail is narrow. The root is a right angle structure, see Figure 6 . When using...

Problems solved by technology

When using the current general-purpose equipment to apply induction heating to heat treatment of such parts, there are problems such as obvious sharp corner effect and difficult heating at the root, and it is difficult to achieve the effect of heating at the same speed on the horizontal and vertical surfaces of the rotating right-angle structure, which makes the quenching of the parts Difficult to meet technical requirements

For a long time, this type of parts has been a bottleneck problem restricting production
