Definitions
- the invention relates to a device for deforming thin-walled material, from a substantially flat piece of material to a sleeve-shaped body, with two form matrices, at least one of which is arranged to be movable relative to the other.
- the flat sheet metal or the like is usually first. rolled and then further shaped into the finished body.
- Such a device is known from DE 197 43 436, for example, which is very well suited for forming large quantities.
- the invention has for its object to design a device of the type mentioned so that the forming can be done in a single operation.
- the inserted sheet metal is bent into the mold that is being formed and, when the two molding dies are completely swung together, reaches the shape defined by these dies.
- An advantageous embodiment of the invention resides in the fact that fingers which interpose between each other are arranged on the end of the two molding dies facing the swivel joint of the molding dies.
- the board can touch these fingers when bending, even though the two form matrices are not yet in contact with each other. This prevents the sheet from escaping into the space below the form die.
- a further advantageous embodiment of the invention is characterized in that a centering sword is arranged at the end of the two shaped dies facing away from the swivel joint.
- each of the two centering swords can be pivoted out of the mold and the two mold dies can be pivoted together into their end position, in which the body obtains its final shape.
- the centering sword is pivotally mounted on a two-armed lever, on the lever arm facing away from the centering sword, a cam disk or the like. attacks.
- a further advantageous embodiment of the invention is characterized in that a removable closure part is preferably provided adjacent to the centering sword.
- the two closure parts are removed from the molding dies, which creates an open gap through which the weld seam can be produced to close the body.
- the closure part is mounted so as to be longitudinally displaceable.
- This longitudinal displacement can be carried out particularly easily.
- Show: 1 shows a schematic sectional illustration of a forming device with two molding dies in the open state
- FIG. 2 shows the forming device according to Fig.l in an almost completely closed state
- FIG. 3 shows a detail of a form die on a larger scale.
- FIG. 1 denotes a device which is used to form a sheet metal blank 2 into a shaped body 20.
- the device 1 contains two molding dies 3 and 4, the hollow shape of which corresponds to the outer shape of the later molded body 20.
- the two form matrices 3, 4 are pivotally mounted about a common pivot point 5, it being entirely possible to pivotally mount only one of the two form matrices and to arrange the other in a fixed manner.
- the two mold dies 3, 4 are each equipped with a plurality of fingers 6 and 7, which engage between the two mold dies when pivoting against one another.
- a centering sword 8 or 9 is arranged, against which the respective end of the sheet metal plate 2 can be supported.
- the two shaped dies 3, 4 are pivoted together, the respective end of the sheet metal blank 2 moves against this centering sword 8 or 9, and the sheet metal blank 2 is bent into the die shape as indicated in FIG. 1.
- the fingers 6 and 7 prevent the middle section of the sheet metal plate 2 from moving downward as long as the lower ends of the two form matrices are not yet in contact with one another.
- the two form matrices are closed to such an extent that the centering swords lie against one another, they are pulled out upwards and the two form matrices are completely laid against one another.
- the two ends of the sheet metal board 2 then lie against one another without a gap.
- a locking part 10 and 11 there is a locking part 10 and 11, respectively, which can also be moved out after removing the centering swords and completely swiveling the two mold dies together.
- a gap 12 is formed in the mold formed by the mold dies, through which the two ends of the molded body 20 can be welded to one another.
- FIG 3 shows the upper section of a form die 4 with the centering sword 9 mounted thereon and the closure part 11 on a larger scale.
- the centering sword 9 is attached to a pivotally mounted lever 30 which is actuated by a cam 31 which is mounted on a rotatable disc 32.
- a piston 33 acts on this cam 31, which generates the rotary movement of the disk 32 and thus the pivoting movement of the lever 30.
- Another piston 34 engages the closure part 11 via a plurality of levers 35 and 36 and moves it from its closed position into its open position and vice versa.
- a spring 37 can also act on the lever 30 of the centering sword, as indicated, which moves the lever into the retracted position of the centering sword.
