Definitions
- the invention relates to a set of tools for shaping a sheet.
- a set of tools for shaping a sheet comprising a mallet comprising a handle on which is mounted a hollow head, of polymer material, which houses a mass made of a denser material, and at least one pile, the shape of which is chosen according to the work to be carried out on the sheet, and intended to be placed on the other striking side of the sheet.
- the invention relates to a set of tools described above, characterized in that the pile comprises a body of dense material coated with a layer of composite polymer material in order to reduce the rebound phenomena during striking. .
- the head comprises a frustoconical body delimited by a basic transverse face into which opens the cavity which is oriented along the axis of the head, and on which is fixed a tip adapted to the type of striking, which closes the cavity.
- the head comprises a cavity of cylindrical shape, substantially identical to the general external shape of said head, so as to distribute the internal mass through the head.
- the end piece comprises a tail screwed into the cavity and which axially contains the mass in the cavity.
- FIG. 1 is a schematic exploded view, in section through a longitudinal plane, of the mallet according to the invention
- FIG. 2 is a perspective view of a pile of the tool assembly
- FIG. 3 is a diagrammatic view in cross section, along a vertical plane, of a pile illustrated in FIG. 2.
- the mallet 10 of the tool assembly consists of a handle 12 on which is mounted the head 14 of the mallet.
- This head is made of polymer material, such as polyamide 6-6, which is sufficiently resistant to impact impacts and sufficiently neutral so as not to be aggressive towards the aluminum sheet.
- the polymer material has the advantage of being light enough not to harden the aluminum sheet, however it does not sufficiently absorb the vibrations during the impact shock.
- the head 14 of polymer material is hollow and receives, in its cavity 16, a dense material, such as iron or lead shot, or a mass 18 of suitable shape.
- a dense material such as iron or lead shot
- a mass 18 of suitable shape is thus obtained with the same mass properties as steel, to avoid the effects of rebounds during striking.
- the tool comprises a head 14 which comprises a frustoconical body delimited by a basic transverse face 20 into which the cavity 16 which is oriented along the axis of the head 14.
- the conical end 22 offers a sufficient level of striking precision for closing crimps of vehicle doors.
- the head 14 has an edge 24, substantially parallel to the axis of the handle 12, and from which the conical end 22 of the hammer is extended, at an angle of about 20 degrees, relative to this edge 24.
- the other end of the head is closed by a nozzle 26 which can be screwed, clipped or fitted.
- This has the advantage of fixing, on the head 14, the nozzle 26 adapted to the type of shaping necessary for the sheet.
- This endpiece 26 has a tail 28 which holds the mass 18 longitudinally, inserted into the cavity 16 of the head 14 to prevent its movement during the striking action.
- the tool assembly also includes at least one pile 30, illustrated in FIGS. 2 and 3, made of a dense material 32 and coated with a layer 34 of polymeric material, in order to reduce the rebound phenomena during striking.
- This pile 30 makes it possible to perfectly control the reshaping of the straightened sheet and reduces the rebound phenomena created by striking.
- the use of these piles depends on their form.
- the heap illustrated in FIGS. 2 and 3 is a heap of the corner type with a broken angle and rounded surface 36 which can be used for straightening or passing over all the places of the material to be worked.
- the pile 30 is placed on one side of the sheet, and the other face is struck by the mallet 10 in order to straighten it.
- the straightening of the sheet is carried out without work hardening thanks to the polymer material, and this tool offers the advantage of being much quieter than a steel tool when in use.
