Description
Technical Field
The invention relates to a telescopic electromagnetic induction heating tool for heating a large arc-shaped metal workpiece, and belongs to the technical field of electromagnetic induction heating.
Background
In the traditional manufacturing industry, metal workpieces are often required to be heated, and the traditional heating modes are generally two types:
1. the flame heating mode is adopted, fuel is consumed, waste gas and waste residue are discharged in the heating process, most heat is dissipated to the environment in the heating process, a large amount of energy is wasted, the energy utilization rate is low, the workpiece is always contacted with the fuel and oxides thereof in the heating process, foreign matters are easy to invade, and therefore the quality of the workpiece is influenced;
2. resistance wires are adopted for heating, and the resistance wires are commonly used in the heating mode. However, resistance wire heating has the disadvantages of slow heating speed, large heat loss, low heat efficiency and easy damage.
Electromagnetic induction heating is to generate an alternating magnetic field around an induction coil by passing an alternating current with a certain frequency through the coil. The electromagnetic induction action of the alternating magnetic field generates a closed induction current, namely an eddy current, in the workpiece. The generated vortex causes the metal to directly heat, thereby greatly reducing the heat loss and improving the energy utilization rate. Therefore, electromagnetic induction is a great trend in heating metal workpieces.
An electromagnetic induction heating apparatus is a heating apparatus manufactured by applying the principle of induction heating. Heating tools are important components of induction heating equipment.
The basic fittings of the existing complete set of electromagnetic induction heating equipment comprise: induction heating host computer, power cord, extension cord, induction heating frock. Wherein, the induction heating host computer converts the power frequency electric current of input into high frequency electric current, produces high frequency alternating magnetic field through heating frock, and the work piece that is heated cuts the magnetic line of force, and inside produces powerful vortex to self generates heat.
A common electromagnetic induction heating tool is composed of a metal wire wrapped with an insulating layer and a supporting material. The metal wire is coiled into a spiral shape and then fixed on various types of supporting materials such as high silica cloth and epoxy resin materials.
The electromagnetic induction heating tool is divided into a hard tool and a soft tool. The soft tool can change the appearance, the size and the size of the tool at will, but the preparation work before heating and the ending work after heating are more complicated. The shape of the hard tool cannot be changed, but the preparation work before heating and the ending work after heating are simpler.
At present, an electromagnetic induction heating tool is generally used for heating metal workpieces with corresponding radians, such as pipelines, bearings and the like. The distance between the tool and the heated workpiece is kept within 1-3 cm, when the distance exceeds 3cm, the induction heating host cannot output all power, and when the distance is too large, the host can report errors and stop working; and because the diameter of the heated workpiece reaches 8m, the whole welding line cannot be heated simultaneously by adopting the existing heating tool, so that the mode that the tool is fixed and the heated workpiece is heated in a rolling mode is adopted. However, due to the deviation of the processing precision, the diameter of the large arc-shaped metal workpiece can deviate, the uniform distance between the large arc-shaped metal workpiece and the heating tool cannot be kept, the heating is interrupted when the distance is too large, and the heating tool is crushed when the distance is too small.
