Embodiment 1

[0022] Embodiment one, such as figure 1 , figure 2 As shown, the present invention provides an overall supersonic heating method for variable-section rods, which is applied to an overall supersonic heating device for variable-section rods. Direction Horizontally set at least two or more positioning parts 3 for placing rods with variable cross-sections, a super-audio heating power supply 4 and a temperature detector 5. The heating coil 1 is inside an insulating casing 2 . The insulating shell 2 is provided with a through hole along the opening axis direction of the heating coil 1 . The through hole is located in the cavity of the heating coil 1 . The positioning piece 3 is located in the through hole and surrounded by the heating coil 1 , and a groove is provided in the middle of the upper end surface of the positioning piece 3 . The axis of the groove is perpendicular to the opening axis of the heating coil 1. The rod body of the variable-section rod 6 is placed in the gr...

Embodiment 2

[0032] Embodiment two, such as image 3 As shown, in actual work, the crawler conveyor belt 8 can also be used instead of the positioning member 3 . Crawler conveyor belt 8 is fixed on the frame 7. During work, the variable section rod 6 is placed between two adjacent track shoes 81, the rod body of the variable section rod 6 is limited by using the gap between the adjacent track shoes 81, and the variable section of the variable section rod 6 is adjusted. The included angle with the opening axis of the heating coil 1 is within the range of 30°-40°. Afterwards, the crawler conveyor belt 8 is started to send the variable-section rod 6 into the supersonic heating equipment, and the heating coil 1 is started to heat the variable-section rod 6 . The probe of the temperature detector 5 detects the temperature of the variable section rod 6 . When the temperature reaches the set value, the temperature detector 5 sends an alarm signal, and the power supply can be disconnected, and ...

Abstract

The invention discloses a supersonic-frequency heating method for uniformly heating an overall variable-section rod part. The supersonic-frequency heating method is applied to supersonic-frequency heating equipment an overall variable-section rod part. The supersonic-frequency heating method for uniformly heating the overall variable-section rod part comprises the following steps of: (1) placing ato-be-heated variable-section rod inside a groove of a positioning part; (2) regulating the included angle of a variable section of the end of the variable-section rod and the axis of an opening of aheating coil to make sure that the included angle is within the range of 30-40 degrees; (3) starting the heating coil to heat the variable-section rod; and (4) taking out the variable-section rod after heating is ended. Compared with the prior art, a forging plane of the end part of the variable-section rod and the axis of the opening of a supersonic-frequency heater are inclined by 30-40 degreesso that the projection area where a vortex magnetic force line passes through the plane of the end part is the most suitable, and thus the aim that the overall heating temperature of the rod body isconsistent is realized. Thus, gold-phase structures of the two ends and the middle parts of the variable-section rod are the same in transformation and the same in hardness. The occurrence of fatiguefailure of the variable-section rod is effectively prevented.

Description

technical field [0001] The invention relates to a heating method, in particular to a supersonic-frequency heating method for uniformly heating the whole variable-section rod. 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 equipment 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 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 resistance ...
