Definitions

  • the invention relates to a method for the non-cutting production of a hub of a gear part comprising the hub from a sheet metal plate.
  • Gear parts designed as sprockets or as pulleys, in particular poly-V belt pulleys, are used extensively in motor vehicle construction and are nowadays often produced from a round blank by pressing processes.
  • the formation of the toothing and / or the grooves is also possible in the pressing process, while the installation of the required hub is difficult.
  • the actual hub is a sleeve-shaped in the area of the axis of rotation
  • the hub of a gear part is produced by connecting a prefabricated cylindrical sleeve part to the gear part, four methods being used as the connection, namely one soldering of the two components , welding the two components, the connection of the two components by friction welding and finally it is possible to manufacture the gear part by a forging process.
  • the cost of producing the hub as a turned part is relatively high.
  • Manufacture sheet metal parts these outer lamellar beams are manufactured in two press passes. A total of 27 processing stages are required to produce such an outer arm. They comprise 10 drawing, 7 calibration, 2 ironing and drawing processes, 7 cutting processes and 1 upsetting process. The structure is torn apart by the drawing work, i. H. the material structure is tired. In addition, pulling operations are usually associated with inaccuracies which can have a disadvantageous effect on a transmission part.
  • the object of the invention is to simplify the generic method and to carry it out in one work step without the material structure of the transmission part being influenced undesirably.
  • the hub of the gear part is produced in one work step, but it is also possible that the wall thickness of the hub is greater or greater than the wall thickness of the sheet metal plate of the gear part, so that the required strength is achieved here to transmit the torque is reached.
  • the hub is molded onto the intermediate pulley product in one setting on a spinning machine.
  • the method is used, there is the possibility of producing intermediate pulley products for all known production methods for pulleys, since the thicknesses in the contour area and in the professional area of the intermediate pulley products are determined by the pressing method used. Exemplary embodiments of the methods according to the invention are explained below with reference to the drawings. The drawings show in
  • Fig. 1 a clamped hood in one
  • FIG. 5 shows a sheet metal plate inserted into a pressing device
  • FIG. 6 the deformation of the sheet metal plate to
  • a hood 2 is shown, which is fixed to a tool 3 of a main spindle 4 by a chuck 15 belonging to the tool 3. 35
  • the tool 3 has a zen in the axial direction trisch projecting tool pin 5, which rests on the inside of the clamped hood 2 or comes to rest, with a front 8 is applied to the outside of the hood 2.
  • the double arrow F shown in FIG. 1 clarifies the direction of movement of the main spindle 4 and the step-up 8 for fixing the hood 2.
  • FIG. 2 shows that the cover 2 is deformed in the direction of the cylindrical tool pin 5 by the action of pressure rollers 9 and 10, the deformation then being continued as far as possible by using a form roller 11 shown in FIG. 3 until the hood has wrapped around the tool pin 5.
  • the hood 2 has partially applied as a round 6 to the top of the tool 3, while the remaining part of the hood 2 has waved around the tool pin 5 according to FIG. 3.
  • this undulating region around the tool pin 5 is pressed together by thickening rollers 1 and 12 and 14, the part of the hood 2 then serving as a hub is cylindrical, the wall thickness of this cylindrical part Projection 7 can be greater than the wall thickness of the blank.
  • the delivery 1 direction of the compression rollers 12 and 14 is illustrated by the arrows F in FIG. 4.
  • the cylindrical projection 7 so that it can receive a shaft or a pin.
  • the opening of the cylindrical projection 7 can either be done by cutting off the bead of the cylindrical projection 7 shown in FIG. 4, but it is also possible to cover the end wall of the cylindrical projection 7 with holes or the like. to open so that the hub finally achieved has the bulge which contributes to the strength.
  • the flanges 16 and 17 can then be machined to design the gear part.
  • 21 denotes a sheet metal plate 35 which is connected to a main spindle 22 arranged tool is arranged in that in the illustrated embodiment, the tool 23 carries a tool pin 24 onto which the sheet metal plate 21 can be placed by means of a hole provided centrally in the sheet metal plate.
  • 25 is a front attachment which is movable back and forth and comes into contact with the tool pin 24 in its working position.
  • the presetter 25 has in the area of the sheet metal plate 21 an outer diameter that is larger than the outer diameter of the tool pin 24, so that thereby a stop designated in the drawing with 34 is created, to which the inner part of the sheet metal plate deforms Can create sheet metal.
  • a chuck working together with the tool 23 is designated, which, after a pressure roller 26 has bent the outer edge region of the sheet metal plate, defines this edge area of the sheet metal plate 21, so that migration of the sheet metal plate is prevented.
  • the pressure roller 21 can be moved towards the tool pin 24 in the direction of the arrow shown in FIG. 6 and, as this is particularly clearly shown in FIG. 7, reduces the mean wall thickness of the sheet metal plate 21, this being due to the pressure roller 26 pressed material flows into the space which is present around the tool pin 24 and, as is clearly shown in FIG. 8, bears against the stop 34, so that a cylindrical projection 28 is thereby created which is in the intermediate pulley product the actual hub 27 according to FIG. 9 forms. From the drawing, in particular in comparison to FIGS.
  • edge area of the sheet metal plate 21 defined by the chuck 29 is thicker than the central edge area of the sheet metal plate 21 and that again the cylindrical projection 28 is essential has a greater material thickness than the central edge region of the sheet metal plate 21.
  • the edge area of the sheet metal plate 21 defined by the chuck 29 is thicker than the central edge area of the sheet metal plate 21 and that again the cylindrical projection 28 is essential has a greater material thickness than the central edge region of the sheet metal plate 21.
  • this wall thickness of the cylindrical projection 28 can be determined.
  • the trailing roller 35 15 shown in FIGS. 7 and 8 prevents the material of the sheet metal plate 21 from bending up during the pressing process.
  • the pulley - as under ⁇ . and shown - should have a contour area K. and possibly a perforation 11, this contour area can possibly be made with the perforation on a press from that of the
  • the material structure of the intermediate pulley product is not subject to any negative influences, such as. B. in welding and forging,
  • the inside diameter of the hub can be produced by the pressing process without subsequent rolling
