Abstract
The invention is directed to a dent removing device for removing of dents in ferromagnetic sheet metals by way of inductive heating, said dent removing device comprising a working head with a housing with at least one working face foreseen to be brought in close contact with a dent in a sheet metal and at least one magnetic field generator for generating a magnetic field. According to the invention, the at least one working face comprises a recess for visual control of the dent removing, recess extending at least partially across the at least one working face.
Claims13
A device for removing dents in sheet metal structures by inductive heating comprising:
- a. a working head including
- a housing with at least one working face to be brought in close contact with a dent in a sheet metal;
- at least one magnetic field generator for generating a magnetic field, wherein the magnetic field generator comprises an electrical coil, wherein the magnetic field generator comprises a substantially U shaped core, said core comprising a first and a second leg and a yoke portion wherein the electrical coil is interconnected to the core;
- and
- b. a power supply and control unit;
- and
- c. a cable suited to connect the power supply and control unit with the working head;
- wherein the power supply and control unit comprises:
- d. a time regulation means to control the duration of supplying the power to the working head;
- and
- e. a power regulation means to control the power supplied to the working head.
