Induction heating device

Abstract

The invention discloses an induction heating device, and belongs to the technical field of curved plate processing. The double-circle gyroscope is arranged to adjust the rotational freedom degree of the induction coil in the x-axis direction and the y-axis direction, the vertical lifting unit is arranged to adjust the movement freedom degree of the induction coil in the z-axis direction, the structure is simple, and the cost is low; the vertical lifting unit is used for controlling the moving freedom degree of the induction coil on the z axis, the vertical lifting unit is used for controlling the moving freedom degree of the induction coil on the z axis, the vertical lifting unit is used for controlling the moving freedom degree of the induction coil on the z axis and is similar to a spring, and it is ensured that universal wheels at the bottom of an inner ring make close contact with a plate all the time through pressing force of the vertical lifting unit; the posture of the coil is adjusted by means of contact force between the universal wheels and the plate, it is guaranteed that the distance between the induction coil and the plate is stable in the heating process, the action effect of the contact force is transient, adjustment of the posture of the coil can be completed instantly theoretically, and therefore the device can adapt to the rapid moving heating process of the large-curvature plate. The shape of the plate does not need to be monitored, and the cost is further reduced.

Description

technical field [0001] The invention belongs to the technical field of curved plate processing, and more particularly, relates to an induction heating device. Background technique [0002] Thermoforming is a common method for machining complex curved sheets. Common types of heat sources used in thermoforming methods include oxyacetylene flames, lasers, and electromagnetic induction heating. Due to its high efficiency, clean energy and easy control, electromagnetic induction heating has gradually become the preferred method of thermoforming. [0003] The complex curved sheet is composed of curved surfaces with various curvatures. Typical complex surfaces include sail surface, saddle surface and torsion surface, and other complex surface shapes can be regarded as the combination of these three typical shapes. Due to the complexity of the shape of the plate, it is difficult to ensure a stable distance between the coil and the plate during the heating process, which leads to ...

Problems solved by technology

However, sensors adapted to magnetocaloric conditions are generally more expensive

And a complex automatic control system such as a robotic arm is required to meet the needs of distance control, which also increases the cost of equipment

In addition, for the fast-moving heating process of large-curvature plates, the heating accuracy may be reduced due to the untimely response of monitoring and active adjustment, or even unusable
