- a non-conductive material such as, for example, plastic
- the electromagnet 16 is formed from an electrical ring magnet.

- a free space 21 is kept free in the basic body 15, so that the shaft part 18 can move into this free space 21 due to the repulsive force and thus the shaft part 18 can only move in one direction, since the bolt element 5 the opposite side prevents evasion.
- This movement can differ depending on the field of application of the drive device 2, since when used as a denting device 1 a pulling movement and as a striking hammer a striking movement must be carried out.
- the dent removal device 1 If such a dent removal device 1 according to the invention is put into operation, the user must first connect the dent removal device 1 to the sheet 3, i.e. a spot welding process for attaching the electrode element 4 to the sheet 3 must first take place.

- the user has the possibility that he can set the current level at the current source 8 and thus can optimally adapt to the most varied of sheets 3.
- reference values or setpoints for the current level and the time period for the spot welding can be stored in the control device 27, in particular a microprocessor control, arranged in the current source 8, so that by simply selecting a corresponding plate 3, in particular of the material and the sheet thickness, an optimal welding current or an optimal current level is set by the control device 27 via an input and / or output device 31 at the current source 8.

- Adjustment speed is dependent on the magnetic field generated and thus the tensile movement or tensile force can be regulated on the basis of the amplitude height applied.
- the direction of movement of the shaft part 18 corresponds to the pulling movement carried out by the user, corresponding to arrow 32, so that in addition to the pulling movement carried out by the user, a further pulling movement of the bolt element 5 onto the sheet 3 is carried out.
- the lever device 17 or the shaft part 18 is constantly moved back and forth between the rest position and the working position, since a restoring force is generated due to the arrangement of the spring element 19 in the energy pauses and thus a
- Pendulum movement which affects the bolt element 5 as a pulling movement is caused.
- a limiting device 34 which is preferably formed by a bolt in an elongated hole, is arranged in the basic body 15. It is thereby achieved that when the bolt element 5 moves - according to arrow 32 - the movement is stopped by the limiting element 34 and thus only a defined adjustment path can be carried out.
- a further spring element can be arranged in connection with the bolt and the elongated hole, so that a defined starting position for the bolt element 5 is created in the rest position.
- the main advantage for such a dent removal device 1, which is operated with electrical energy, is that a simple control or regulation of different parameters can be carried out.
- Dent removal device 1 is composed of the spot energy for the spot welding process, the pull or impact energy for the pulling movement or striking movement of the bolt element 5 and the number of pulls or strikes for the number of bolt movements. These parameters can be preset by the user via the input and / or output device 31 or can already be setpoints for the individual parameters in the control device

If the shaft part 18 is formed by a permanent magnet or if the shaft part 18 has a core made of a permanent magnet, then it is possible that by pulling the two electromagnets 16 and 35 in opposite or mutual directions, an attractive force and a repulsive force are generated simultaneously and thus an increase in the adjustment speed and tensile force of the shaft part 18 is achieved.
- This type of control can now also be used for the formation of an impact movement or an impact force from the shaft part 18 onto the bolt element 5. To do this, it is only necessary that the current flow through the two electromagnets 16, 35 is reversed, or that the electromagnet 35 is first activated to exert an impact force, so that a movement of the shaft part 18 in the direction of arrow 26 is carried out.
- an adjustment of the shaft part 18 between the two possible Chen working positions is carried out, that is to say that the shaft part 18 is first moved, for example, from its drawn rest position or rest position by activating the electromagnet 16 into the first working position and then by simultaneously deactivating the electromagnet 16 and activating the electromagnet 35 in the second position. position is moved, i.e. an alternating movement is created.

- the control of the individual electromagnets 16, 35 and 45, 46 can be carried out in accordance with the control method as described in FIGS. 1 to 4. It is only necessary to ensure that the shaft part 18 now also has electromagnets 45, 46, so that for a corresponding direction of movement, according to arrow 47, for example in the direction of the connecting device 20, an attractive force of the two electromagnets 35 and 46 is generated, with support a repulsive force can be formed between the two electromagnets 16 and 45. This training the individual

As a result, it is possible that an attractive force or repulsive force can in turn be generated between the two electromagnets 49, 50, as a result of which the movement or the adjusting force of the shaft part 18 can be increased accordingly. This also ensures that a corresponding direction of movement for the shaft part 18 can be determined.

- the current source 8 is formed from a welding current source or a welding device. It is thereby advantageously achieved that a user who already has a welding device can easily remove a sheet metal by simply connecting the welding device to the denting device 1. damage, in particular the deformation 22 can fix.
- the user only has to additionally connect the dent removal device 1 to the public supply network 11, since the control for the pulsed actuation of the electromagnets 16, 35, 45, 46 is integrated directly in the housing and thus a retrofitting of a welding device which is part of the prior art or a welding power source is not necessary.
- the dent device 1 is designed such that the welding device is connected to the sliding contact 29, whereby the spot welding process is started by actuating a switch on the welding device. The user can then release the connection to the welding device or put the denting device 1 into operation by simply actuating the start switch 33, as a result of which the control device 27 carries out a pulsed activation of the electromagnets 16, 35, 45, 46 in accordance with the previously described functional principles.
- the control device 27 carries out a pulsed activation of the electromagnets 16, 35, 45, 46 in accordance with the previously described functional principles.
- the use of an external welding device has proven to be advantageous for weight reasons.
- FIGS. 1, 2, 3; 4; 5; 6 shown embodiments form the subject of independent solutions according to the invention.
- the relevant tasks and solutions according to the invention can be found in the detailed descriptions of these figures.
