Definitions
- the invention relates to a method for forming a sheet metal blank with a central hole which rests on a rotating tool about an axis and has a thickness al and a diameter dl which is smaller than the diameter of the tool.
- the invention has the object to go new ways in the transformation of sheet metal blanks by means of spinning rollers.
- one or more spinning roller preferably first immersed axially in the material of the sheet metal blank and then moved radially outward (this is to be understood that the way pressure roller at least one component of movement in the radial direction), whereby the surface of the circular sheet metal plate radially is increased in all directions, so that from the sheet metal blank with the initial diameter dl and the thickness al a rotationally symmetric part, in particular a sheet metal blank with a larger diameter d2 and at least partially or continuously reduced thickness a2 is produced.
- the invention it is possible to produce a sheet metal blank or directly a rotationally symmetric part, in particular a gear part, with a larger diameter d2 and an at least partially or continuously reduced thickness a2 from a sheet metal blank having an initial diameter d1 and a thickness al. It is even possible to increase the diameter by more than 10%, in particular more than 20%.
- the term of the sheet metal blank is not too narrow in view of the part produced by the forming. It is on the one hand possible to produce a flat sheet metal blank. However, this can also be contoured if the tool is contoured accordingly.
- the sheet metal blank can be processed or further processed directly into a gear part or the like.
- the method can be used in a wide variety of fields.
- a preferred application is the enlargement of "small" circular blanks, as they occur, for example, in the production of wheel discs for lorries, which would otherwise have to be scrapped.
- the invention is a use for a different purpose, eg for the production of Radschdorfln for Smaller commercial vehicles still possible. The resulting cost advantage is not to be underestimated.
- FIG. 1 shows a metal blank as the starting workpiece
- Fig. 2 shows the metal blank of Fig. 1 in dashed lines on a tool and with solid lines after the forming.
- Fig. 1 shows a sheet metal blank 1, preferably with a central hole 2, which rests in Fig. 2 on a rotatable about an axis 3 tool 4 (on a spindle not shown here a spinning machine) and has a thickness al and a diameter dl.
- the sheet metal blank 1 is preferably held on the central hole 2.
- the axial length of the pin 5 may be smaller, the same size or larger than the thickness dl of the circular sheet metal dl.
- the sheet metal blank 1 is preferably made of a cast iron or other formable by pressing other metal.
- the tool 4 extends radially in all directions beyond the outer circumference of the sheet metal blank 1 with a preferably circular shape. It preferably has a flat surface, but may also be formed contoured.
- one or more freely rotatable press rollers 7 are arranged, which can be delivered at least axially in the direction x of the workpiece and radially in the direction r, also in superimposed movements.
- the spinning roller 7 is delivered axially in the direction x at a distance from the outer circumference, preferably close to the centric hole or even at the edge of the centric hole, whereby it is immersed in the workpiece , Then or while it is radially moved in the direction r outward so that it presses material of the sheet metal blank 1 in front of it radially outward.
- the surface of the blank 1 is radially enlarged in all directions, and surprisingly without crack formation in the outer circumferential region.
- a freely rotatable hold-down roller 8 in the outer peripheral region can additionally prevent the blank material from bulging out of the plane of the sheet metal blank 1.
