Definitions
- the invention relates to a method for molding from sheets to conical pipe jackets according to the preamble of claim 1 the invention a device according to the preamble of claim 5.
- the invention is therefore based on the object Rounding plates in a simple way.
- Figure 1 shows a rough schematic of the side view a device for the conical shaping of sheets.
- a die 1 is shown, which has an inner one has in the longitudinal direction conical cavity 2, the indicated by the broken line 3 in the figure which is the lowest generatrix of the conical cavity 2 represents part of a truncated cone forms.
- Figures 2a and 2b show the die 1 with their conical cavity 2 in vertical section along the Section lines B-B and C-C of Figure 1.
- the stamp 4 is also tapering in the longitudinal direction as part 12 of a truncated cone shaped and corresponds in shape in the area that can be immersed in the die 1 is determined, the shape of the conical cavity, however reduced by the thickness of the sheet to be deformed.
- the stamp 4 is also in FIGS.
- the drive of the stamp 4 can be represented only schematically by a Crank assembly 10,11 take place, which the Stamp 4 moved into the die cavity 2 and there pressed against the sheet and the stamp 4 along with arrow A symbolized curve again from the matrix away.
- Corresponding crank drives are the expert common and need not be shown here. Instead of using a pivot axis 5 and one
- the crank mechanism can also have any other actuating elements, e.g. hydraulic or pneumatic actuators are used, which according to the stamp the curve shown or another curve shape move according to the description below and into the Insert the matrix and lead out of it.
- Figure 3 shows the same device in one Starting position, with a sheet 6 to be deformed above the Die cavity is located.
- the stamp 4 is now arranged in such a way that he essentially the sheet 6 in the starting position touched along its entire length so that the subsequent deformation of the sheet over the entire Sheet length starts at the same time.
- Figure 4 shows the stamp 4, with its curved movement into the die 1 immerses in a position where it is approximately half immersed in the die, the latter is shown transparently in the drawing, so that the stamp 4 can be seen in its position in the die is.
- FIG. 5 shows the stamp 4 in its end position, the curve movement preferably taking place in such a way that the stamp over its entire length essentially at the same time the sheet to lie in the bottom of the die brings. In this way, the sheet becomes evenly conical deformed like the shape of the stamp and die equivalent.
- the end position shown in Figure 5 can pressing the sheet in a manner known per se to prevent reshaping.
