Variable cross-section rod piece overall superaudio frequency heating equipment

Abstract

The invention discloses variable cross-section rod piece overall superaudio frequency heating equipment which comprises a superaudio frequency heating device used for heating an overall variable cross-section rod, a receiving device and a conveying mechanism. The heating device comprises a heating zone and a discharging opening, the conveying mechanism comprises a conveying belt used for feeding the variable cross-section rod to the heating zone, and the conveying belt is provided with a ceramic piece; and the receiving device is provided with an opening, and the output end of the conveying mechanism is located above the opening. Compared with the prior art, ceramic has the high melting point, the high high-temperature strength, the small high temperature creep property, the good resistance to heat shocks, good resistance to corrosion, good resistance to oxidation and the good structure stability and the like. The ceramic piece is used on the conveying belt, the conveying belt is prevented from being subjected to superaudio frequency induced magnetization, and high temperature deformation of the conveying belt is prevented. Compared with a traditional metal conveying belt, the service life of the conveying belt with the ceramic piece is greatly prolonged. Meanwhile, the conveying belt which is stable in structure and provided with the ceramic piece can guarantee that the deformation is reduced to be minimum after the variable cross-section rod is heated.

Description

technical field

[0001] The invention relates to the technical field of heating, in particular to an integral super-audio frequency heating device for variable-section rods. Background technique

[0002] At present, in the production industry of automobile stabilizer bars, a commonly used process is to first conduct resistance heating on the stabilizer bar blank, and then use a special forming machine to bend it in a hot state, and then quench it. Among them, the device usually used in resistance heating includes two pairs of heating electrodes. Select the electrode clamping point at the middle part of the two ends of the stabilizer bar at a certain distance from the broken end, place the rod body, and the heating electrodes clamp the stabilizer bar. In this way, the two pairs The part of the rod body between the heating electrodes and the electrodes form a loop, and the middle part of the stabilizer rod is equivalent to a resistor. After the power is turned on, the resistanc...
