Definitions
- the invention describes a dent device and a support element, as described in claims 1, 12 and 22.
- EP 0 992 313 A1 discloses a manually operable dent removal device for processing sheet metal damage, which consists of a base body, a support element fastened to it, an electrode holder and an electrode which can be connected to the electrode holder.
- Actuation of the dent removal device for the vertical movement of the electrode is arranged in a tong-like lever device, which consists of two levers, one lever being rotatably mounted on the base body and the further lever being rigidly attached to the base body.
- the electrode holder is movably connected to the electrode via a slide device with the rotatably mounted lever, the electrode being arranged below the base body between the latter and the disk-shaped support element.
- the electrode protrudes through a hole in the disk-shaped support element.
- the electrode is attached to the sheet by means of a spot welding process.
- the lever device If the lever device is then actuated, the rotatably mounted lower lever moves in the direction of the upper lever, the electrode being moved along with the slide device. As a result of this height movement, the electrode is now moved through the support element into the free space between the base body and the support element, so that the sheet metal damage is extracted.
- the disadvantage here is that, despite the specially designed support element, it is not possible to position the electrode correctly on the sheet metal, since the electrode is covered by the base body.
- the invention has for its object to provide a dent device for processing sheet metal damage, and a support element for a dent device, with which easy handling and good positioning is made possible.
- a lever is U-shaped and has two legs, one leg of this U-shaped lever being mounted on an axis in the base body and the second lever being arranged between the two legs of the U-shaped lever and is rotatably connected to the base body, and that the electrode holder, in particular with the electrode, is arranged in the lower leg of the U-shaped lever.
- the advantage here is that the special design and composition of the individual elements or individual parts creates a very compact and easy-to-use device.
- the dent removal device is formed from a few parts and thus the manufacturing or assembly effort for assembling the parts is very low, since the dent removal device consists of a few basic elements, namely the base body, the support elements, the electrode holder, the Lever device consisting of two levers and the connecting element, which is formed via axles or axle bolts and
- the special design of the individual parts means that they can be produced by machine, and thus the manufacturing costs are very low.
- Another advantage is that the one-piece design of the U-shaped lever allows for very good positioning and handling of the electrode on the sheet to be machined, since the connection of the electrode to the U-shaped lever is free of play, and thus every movement of the Dent removal device directly affects the electrode.
- the lower leg of the U-shaped lever is connected to the base body via the axis, as a result of which is achieved that the center of gravity of the denting device is very low and thus the tilting behavior of the denting device is improved when actuated.
- the lower leg of the U-shaped lever is longer than the upper leg, which advantageously means that it protrudes beyond all parts of the denting device and thus a free field of vision is achieved on the end region of the leg. It is also achieved that the rotary movement of the electrode is improved and thus assumes an almost straight course.
- a connecting bolt is arranged between the U-shaped lever, in particular the lower lever, and the further lever of the lever device, whereby an advantageous effect is that a force transmission between the two levers is achieved.
- the connecting bolt is movably connected to the two levers and transmits the movement of a lever to the further lever, which advantageously has the effect that a relative movement of the two levers to one another arises and thus easy handling of the dent removal device is achieved.
- an adjusting device in particular a screw, is arranged on a lever, by means of which the adjustment path between the two levers can be adjusted relative to one another.
- the advantage here is that the adjustment path or the relative movement of the two levers can be limited to one another and thus an adjustment of the height movement for the electrode can be carried out at the same time.
- a groove or bore is arranged in the upper leg of the U-shaped lever, via which a control cable for a switching element for activating a current flow from a welding device or a current source can be inserted for a spot welding process.
- a connection device for a power supply is arranged on the U-shaped lever, in particular on the cross leg.
- the axis for the mounting of the U-shaped lever on the base body is electrically insulated, which advantageously ensures that no current is transmitted to the other parts, so that these parts come into contact with another object, in particular the one to be processed Sheet metal, no short circuit can occur and thus welding of the parts is prevented.
- the support element is designed in accordance with claims 12 to 21, as a result of which a large contact surface can be achieved and thus a tilting of the denting device is prevented when the lever device is subjected to a corresponding force.
- the object of the invention is achieved in that the support element has a base body, on each of which a rotatably mounted leg element is arranged, and that the base body is connected to the dent removal device.
- the advantage here is that the rotatable mounting of the leg elements during positioning the electrode can be moved laterally, which improves the field of view of the electrode. The leg elements can then be positioned such that they form a secure support.
- the base body of the dent removal device according to claims 1 to 11 forms the base body of the support element. This advantageously means that an additional element can be saved for this dent removal device.
- the leg elements are each supported via an axis, which advantageously ensures that the support element is produced economically.
- the base body is connected to the denting device by means of a spacer element, so that adaptation to the different known denting devices is possible in a simple form.
- leg elements it is possible for the leg elements to be adjustable in such a way that they rest in the outer edge region of a sheet metal damage, in particular a dent, so that an optimal support can always be achieved when processing a sheet metal damage.
- leg elements are mirror images and essentially have an L-shaped shape, a projection being arranged in a bearing area in the bearing area Angle of 90 ° to a side surface is deformed, which advantageously ensures that a simple attachment to the base body of the denting device is created.
- leg elements form a longitudinal web in the region of the electrode, which advantageously means that the field of view of the electrode is not restricted.
- the leg elements form an almost continuous surface in the area of the electrode, that is to say each has an extension which extends approximately to the central axis of the electrode, these extensions having a recess through which the electrode passes without contact extends, whereby it is achieved that the sheet damage can be prevented by the extensions.
- leg elements it is possible for the leg elements to have a telescopic extension through an extendable insert element. It is thereby achieved that an increase in the contact surface of the denting device can be achieved in a simple form
- the object of the invention is also achieved in that a torch or welding torch for a welding device or for a power source is connected or pluggable to the lever device via a torch body, the torch forming a lever.
- the advantage here is that a power supply for the denting device can be created without additional connecting lines.
- the denting device can be operated without great effort, since only the torch connected to the welding device has to be connected to the denting device.
- An embodiment is also possible in which the burner forms an upper leg of the U-shaped lever, as a result of which the burner can be easily attached to the lever device.
- Claims 1 to 21 is formed, it is achieved that the same functions can be achieved without major design changes.
- lever device or the denting device is a connecting device, in particular in the region of the
- the connecting device has an extension, via which the burner body can be plugged on, as a result of which a simple connection of the lever device to the burner can be created.
- the connecting device has a bore into which the burner, in particular the burner body, can be inserted, as a result of which a quick and secure connection of the burner to the lever device can be created.

- Fig. 1 1 is a side view of another embodiment of the
- Dent removal device in a simplified, schematic representation.
- a dent device 1 for processing sheet metal damage is shown.
- the design of the individual elements or the individual parts is not limited to the shapes or the design shown.
- not all parts or elements are shown in the diagrams shown in FIGS. 1 to 5 for the sake of clarity, with an overall picture being obtained by compiling all of FIGS. 1 to 8.
- the dent removal device 1 is composed of several elements or individual parts, the dent removal device 1 consisting at least of a base body 2, a support element 3 fastened to it, an electrode holder 4 and an electrode 5 which can be connected to the electrode holder 4. Furthermore, a lever device 6, which consists of two levers 7 and 8, is provided for the actuation of the dent removal device 1 for the vertical movement of the electrode 5. The levers 7 and 8 simultaneously form handles for the lever device 6. It is possible that the levers 7 and 8 can be covered, for example, with handles made of known plastic molds. These plastic molds or handles, not shown, can simply be attached using the levers 7 and 8.
- the lever 7 is U-shaped, the U-shaped lever 7 being composed of an upper leg 9, a lower leg 10 and a transverse leg 11.
- the leg 9 or 10 of the U-shaped lever 7 is on an axis 12 on Base body 2 rotatably mounted.
- the lower leg 10 of the U-shaped lever 7 is preferably connected to the base body 2 via the axis 12.
- the further lever 8, which is preferably elongated, is arranged between the two legs 9 and 10 of the U-shaped lever 7 and is rotatably connected to the base body 2 via a further axis 13.
- the U-shaped lever 7 is not formed in one piece, but is formed from several individual parts which are connected to one another accordingly.
- the electrode holder 4 is connected to the lower leg 10 of the U-shaped lever 7, the electrode 5 being inserted into the electrode holder 4.
- the electrode holder 4 is designed in such a way that the electrode 5 can be inserted, for example, via a conventional plug connection, or that, for fastening the electrode 5, a screw can be screwed in, for example, by means of which the electrode 5 can be inserted into a bore in the
- Electrode holder 4 can be fixed.
- the lower leg 10 has an opening 14 for the electrode holder 4, which is preferably circular, the opening 14 being arranged such that the electrode holder 4 or the electrode 5 extends in the direction of a contact surface 15 of the denting device 1.
- the opening 14 is assigned a fastening device 16, which is preferably formed by a screw.
- the fastening device 16 is arranged at right angles and preferably laterally offset to the opening 14, so that the fastening of the electrode holder 4 is achieved by a clamp connection.
- the electrode 5 can be connected directly to the U-shaped lever 7, so that the electrode holder 4 can be omitted.
- the opening 14 is arranged in the end region of the lower leg 10, that is to say on the opposite side of the cross leg 11. So that an improved view of the electrode 5 is achieved, the lower leg 10 of the U-shaped lever 7 longer than the upper leg 9. As a result, the end region in which the opening 14 is arranged protrudes beyond all parts of the denting device 1, so that the electrode 5 is not covered by any parts and thus a user has an unrestricted field of vision on the electrode 5. It is further achieved by the extension of the lower leg 10 that the rotary movement of the electrode ⁇ is reduced by the direct connection of the electrode 5 or the electrode holder 4 with the U-shaped lever 7 and thus an approximately rectilinear movement of the electrode 5 is achieved.
- a connecting element in particular a connecting bolt 17, is arranged between the U-shaped lever 7, in particular the lower leg 10, and the further lever 8 of the lever device 6.
- the connecting bolt 17 is movably connected via a bearing arrangement 18 and 19 to the two levers 7 and 8 and transmits the movement of a lever 7 or 8 to the further lever 7 or 8.
- This connection ensures that the two levers 7 and 8 perform a pliers function, that is to say that the two levers 7 and 8, in particular the upper leg 9 and the lever 8, perform a relative movement to one another, as a result of which the further lower leg 10 is moved accordingly by the integral design of the U-shaped lever 7 and thus the vertical movement of the electrode 5 is created.
- the connecting pin 17 can also be arranged between the upper leg 9 and the lever 8 with a corresponding arrangement in order to achieve the same function.
- a setting device in particular a Screw 20, arranged, via which the adjustment path, that is to say the relative movement between the two levers 7 and 8, can be adjusted is.
- the screw 20 is arranged such that the screw head is arranged outside the space between the upper leg 9 and the lever 8. Of course, it is possible that the screw head itself can form the stop.
- the contact element 3 is attached to the dent removal device 1. It is anticipated that the support element 3 has a base body, which in this case
- Base body 2 of the dent removal device 1 i.e. that when the support element 3 is viewed solely, for example when the support element 3 is used with another dent removal device, this requires a base body for fastening two leg elements 21, 22, this base body subsequently using a spacer element with the
- Dent removal device is connected.
- the design of the base body can be different from the illustrated base body 2 of the dent removal device 1, it only being necessary to ensure that the function of the support element 3 is achieved.
- a rotatably mounted leg element 21, 22 is arranged on the base body 2 on both sides.
- the leg elements 21, 22 are each mounted on the base body 2 via an axle 23, 24 or via insertable or screwable axle bolts, so that a pivoting movement, as shown schematically in FIG. 7, can be carried out with the leg elements 21, 22.
- a pivoting movement as shown schematically in FIG. 7, can be carried out with the leg elements 21, 22.
- the movable design of the leg elements 21, 22 also ensures that the leg elements 21, 22 can be adjusted in such a way that they form a very good support on a sheet metal or an object.
- leg elements 21, 22 can thereby be flexibly adapted to the shape and pressure points on the sheet metal can thus be prevented.
- a major advantage of the rotatably mounted leg elements 21, 22 is that they are the size of the
- Sheet metal damage can be adjusted, i.e. the leg elements 21, 22 are adjusted in such a way that they rest in the outer edge region of a sheet metal damage, so that a very good counterforce can be created for removing the damage to the sheet metal.
- the support element 3 It is essential with the support element 3 that it forms a corresponding base area 25 for the area of the electrode 5, so that a corresponding contact area 15 can be created for the denting device 1.
- the base surface 25 is designed such that a longitudinal web 26 is formed in the region of the electrode 5, which subsequently widens by an enlarged contact surface on the underside of the base body 2 to accomplish.
- the longitudinal webs 26 of the leg elements 21, 22 are designed such that they protrude beyond the electrode 5, whereby tilting of the dent device 1 can be prevented.
- the leg elements 21, 22 are mirror images and essentially have an L-shaped shape, with a projection 27 in the bearing area is arranged, which is deformed at an angle of 90 ° to a side surface 28.
- the projection 27 thus forms a parallel surface to the base surface 25.
- This intermediate space now makes it possible for simple attachment to the base body 2, two aligned bores 29, 30 being arranged on the projection 27 and on the base surface 25 for this purpose.
- the axles 23, 24 can be formed by using axle bolts, the base body 2 having corresponding bores.
- a plastic pad is attached to the leg elements 21, 22. It is thereby achieved that a softer support of the leg elements 21, 22 on the sheet metal is achieved and pressure points can thus be avoided even better.
- the leg elements 21, 22 are not limited to the embodiment shown for the attachment to the base body 2, but can be done arbitrarily, but the function of the pivoting out should be possible.
- a connection device 31 for a power supply from one is attached to the u-shaped lever 7, in particular on the cross leg 11 Welding device or a power source, not shown, arranged.
- This can be achieved in a simple form by means of a screw connection 32, as shown schematically in FIG. 6, wherein a welding cable, indicated schematically, can be attached via the screw connection 32. This ensures that the U-shaped lever 7 serves as a connecting line for the electrode 5.
- the operating principle of the dent removal device 1 is already known and will therefore not be discussed any further. It should only be mentioned that the electrode 5 is attached to a sheet, in particular in a dent in the sheet, by means of a spot welding process, which is then actuated by Lever device 6 the electrode 5 is raised and thus the dent can be pulled out. To detach the electrode 5 from the sheet metal, it is only necessary that a rotational movement is carried out with the denting device 1, whereby the point connection of the electrode 5 is released.
- a groove 33 or a bore is arranged, for example, in the upper leg 9 of the U-shaped lever 7, via which a control cable 34, as shown schematically, for a switching element 35 for activating a current flow from a welding machine or a power source can be inserted.
- the switching element 35 is arranged in the upper leg 9 of the U-shaped lever 7, in particular on an end face 36 of the lever 7, so that the welding process can be started by actuating the switching element 35.
- a remote switch or a welding torch must be actuated for the activation of the spot welding process, the positioning of the denting device 1 having to be carried out at the same time.
- the axis 12 for the mounting of the U-shaped lever 7 on the base body 2 is designed to be electrically insulated, for example the axis 12 being arranged in a plastic bearing or in the U-shaped lever 7 is inserted a plastic element through which the axis 12 extends.
- a bearing arrangement 18, 19 is also made of a non-conductive material, in particular of plastic. The remaining parts or elements can thus be touched without danger or these parts can come into contact with the sheet metal to be machined without additional insulating elements, since the sheet metal to be machined contacts the opposite pole is connected and thus a short circuit between the dent device 1 and the sheet is prevented. So that the user of the denting device 1 does not come into contact with any current-carrying part, it is only necessary that the lever 7, in particular the upper leg 9, is insulated, thereby increasing the safety of the denting device 1.
- the movement sequence or the functional sequence of the dent removal device 1 is shown schematically, the connection of the electrode 5 with a plate-shaped object, in particular a body sheet metal 37 of a vehicle, for repairing damage , a so-called dent 38, is attached.
- the basic position of the dent removal device 1 is shown in FIG. 6, from which it can be seen that the electrode 5 projects beyond the contact surface 15 or below the base surface 25 of the leg elements 21, 22.
- the electrode 5 can be inserted into the dent 38 and welded in place using a spot welding method.
- the leg elements 21, 22 are pivoted out to the side, as shown in dash-dot lines in FIG. 7. After the electrode 5 has been welded on, the leg elements 21, 22 are pivoted back into a corresponding position in which a good support can be achieved on the body panel 37.
- the leg elements 21, 22 are preferably positioned in the edge region of the dent 38, so that good resistance can be created for the pulling movement of the electrode 5. In order to prevent the dent 38 from being pulled over, the user can make a corresponding adjustment via the screw 20 before or after welding.
- the user In order to be able to remove the damage or the dent 38 or to take it out, the user must now operate the lever device 6, such as this is shown in Fig. 8, that is, the lever 8 and the upper leg 9 are pressed together, whereby the lower leg 10 and the upper leg 9 are raised by the connecting bolt 17 and the lever 8 a movement to the upper leg 9th performs.
- the electrode 5 executes a slight rotary movement during the height movement, as shown by an arrow 39, the damage or the dent 38 being pulled out at the same time.
- this functional sequence can be carried out by a user with only one hand, so that it can also be used in areas which are difficult to access. This is possible because all elements, such as the switching element 35 for activating the welding process, are arranged on the bulge device 1.
- leg elements 21, 22 can be rigidly attached to the base body 2 or for any position to be set in a fixed manner.
- 2 bores 40 with an internal thread are arranged on the base body and extend in the direction of the base surface 25 of the leg elements 21, 22.
- Screws 41 can now be screwed into these bores, as a result of which the screws 41 are screwed onto the surface of the base surface 25 and thus fixation is achieved in any position or resistance is created against an independent adjustment.
- special screws 41 are used, a spring element being arranged in the screw 41, which presses on a final ball and a corresponding resistance can thus be built up.
- a support web 42 is arranged, as can be seen in FIG. 4, on which the lever 8 comes to rest in the rest position.
- 9 and 10 show further exemplary embodiments of the dent removal device 1, with different leg elements 21, 22 being used in each case.
- the leg elements 21, 22 in FIG. 9 are designed such that they form an almost continuous surface in the region of the electrode 5, that is to say they each have an extension 43 which extends approximately to the central axis of the electrode 5, these extensions 43 being a Has recess 44 through which the electrode 5 can extend without contact.
- This continuous surface ensures that when the dent 38 is pulled out, it is impossible to pull it over, i.e. the dent 38 cannot be pulled beyond the height of the contact surface 15, since the extensions 43 of the leg elements 21, 22 form a counter-holder.
- the leg elements 21, 22 are formed such that they have a telescopic extension.
- a longitudinally extending groove is arranged in the base surface 25, into which a corresponding insert element 45 is inserted, which can be pulled out in the longitudinal direction.
- the insert element 45 is designed such that it forms a flat surface with respect to the contact surface 15, that is to the underside of the base surface 25. This configuration ensures that an extension of the longitudinal web 26 of the leg elements 21, 22 is created when the insert element 45 is pulled out, as a result of which an optimal adaptation to the different body panels 37 is possible.
- FIG. 11 shows a further exemplary embodiment, in which the structure is not limited to the exemplary embodiment shown, but can be used with all denting devices, such as the denting device, according to EP 0 992 313 A1.
- a torch 46 or welding torch for a welding device or for a power source is included via a torch body 47 a burner handle 48 connectable or pluggable to the lever device 6, the burner 46 forming a lever 7 or 8, in particular the upper leg 9.
- a connecting device 49 is arranged in the region of the cross leg 11 in the exemplary embodiment shown.
- the connecting device 49 can be of any design, but it must be ensured that a current transmission from the burner 46 to the lever device 6, in particular to the electrode 5, takes place.
- the connection of the dent removal device 1 via a welding cable to the welding device or the power source can be omitted, i.e. the connection device 31 can thereby be omitted.
- the arrangement of the switching element 35 together with the control cable 34 can also be omitted, since the torch 46 has all the elements required, in particular the switching element 35, for starting the welding process.
- the connecting device 49 is designed such that it has an extension 50, over which the burner body 47 is attached. This is possible because the electrode is removed from the burner 46 so that the free space 51 created in the burner body 47 can be used for the connection to the extension 50, ie the extension 50 is designed in such a way that it has exactly the dimensions, in particular the cross section of the free space 51 is adapted, and thus a rigid connection and at the same time a current transfer is created.
- the connecting device 49 has a bore into which the burner 46, in particular the burner body 47, can be inserted. For this purpose, the bore is adapted to the outer diameter of the burner body 47.
- the function of the dent removal device 1, as described above in FIGS. 1 to 10 remains the same, since the burner 46 only has one lever 7, 8, in particular the lever 7, replaced.
- the connecting device 49 is designed to be pluggable, so that an adaptation to the most varied of burners 46 is made possible.
- the connecting device 49 must be adapted accordingly to the functional principle of the respective denting device, since only a lever has to be replaced by the burner 46, the function of the lever device having to be maintained.
- a drive device can be used for automatically operating the dent removal device 1.
- the drive device can, for example, be designed such that it can be constructed by an adjustable cylinder with a corresponding drive, the cylinder performing the movement function of the levers 7, 8.
- the cylinder is arranged, for example, in the free space between the upper leg 9 and the lever 8, so that the relative movement of the levers 7, 8 is carried out by adjusting the cylinder.
