Abstract
Description
Technical Field
[0001] The utility model belongs to the field of gear processing equipment, in particular to a rapid quenching device for industrial gear processing with a protective structure. Background Art
[0002] Gears are mechanical components with teeth on the rim that can continuously mesh to transmit motion and power. Gears have been used in transmission for a long time. At the end of the 19th century, the principle of gear cutting and the special machine tools and tools that use this principle to cut gears appeared one after another. With the development of production, the stability of gear operation has been paid attention to. Gear quenching can greatly improve the strength, hardness, wear resistance, fatigue strength and toughness of steel, so as to meet the different use requirements of various mechanical parts and tools.
[0003] During quenching, the gear is placed in an inductor (coil). When an alternating current of a certain frequency is passed through the inductor, an alternating magnetic field is generated around it. The electromagnetic induction of the alternating magnetic field generates a closed induced current - eddy current - in the workpiece. The distribution of the induced current on the cross section of the workpiece is very uneven. The current density on the surface of the workpiece is very high and gradually decreases inward. This phenomenon is called the skin effect. The electrical energy of the high-density current on the surface of the gear is converted into thermal energy, which increases the temperature of the surface, that is, surface heating is achieved. The higher the current frequency, the greater the difference in current density between the surface and the interior of the workpiece, and the thinner the heating layer. After the temperature of the heating layer exceeds the critical point temperature of the steel, it is quickly cooled to achieve surface quenching.
[0004] When the rapid quenching device for industrial gear processing is in use, the surface temperature of the gear is too high, and the operator may be burned when moving the gear, thus affecting the safety of gear quenching. Utility Model Content

A mounting frame 7 is fixed to the surface of the workbench 2 close to the bevel gear 2 601 through bolts, and a cylinder 8 is fixed to the side wall of the mounting frame 7.

When an alternating current of a certain frequency is passed through the induction coil 10, an alternating magnetic field is generated around it to heat the gear. The support plate 604 is in a circular ring shape, and the outer size of the support plate 604 is adapted to the inner size of the induction coil 10, so that the support plate 604 can pass through the induction coil 10 conveniently.
