Definitions

  • the invention relates to a method for processing a between a counterhold and a guide of one Clamping force held by the workpiece in a surface of the Workpiece a profile e.g. a precision toothing, is molded by a shaped element, as well as a Device for this.
  • Deformations, for example embossing, in workpieces usually take place in punching or fineblanking presses.
  • the workpiece to be machined is between a Brackets and a guide clamped and a stamp guided against the workpiece, this stamp the Embossing in the workpiece.
  • the leadership of the Stamp is usually done in a vertical orientation towards the workpiece, i.e. in an orientation perpendicular to the Surface of the workpiece.
  • several embossing steps are carried out. For example when forming a precision toothing there are three Steps necessary.
  • a stamp on the surface of which is geometrically specific Embossing organs are located slots are embossed.
  • the flanks of the slots correspondingly be reshaped. Especially with sawtooth-like Gears leave the quality of this precision gearing much to be desired.
  • a manufacturing method is known from US Pat. No. 4,318,292 known for a pair of pliers. Both pliers legs grip interlocking, the teeth being oblique Should have side flanks.
  • a molding space is formed by cranking the leg of the pliers, so that the tooth flank, which will later be inclined, in is arranged in the vertical direction to the clamping force.
  • Another step is the cranking of the Pliers legs removed, so that as a result the Tooth flank is at an angle.
  • the present invention is based on the object Method and device of the above Kind of develop with which even more difficult profiles can be exactly in one workpiece can be molded.
  • This procedure has the advantage of being in a single Step in the production of the desired profile in the workpiece.
  • the shaped element itself guided at an angle i.e. the guidance takes place with a vertical and an obliquely offset component.
  • the guidance takes place with a vertical and an obliquely offset component.
  • An inventive device for performing this The method has at least one guide and one Counterholder on, between which the to be machined Workpiece is clamped.
  • Guide or counterholders can plate-like, wall-like or any other design his. It is essential that the leadership Form element is located at an acute angle the workpiece is fed. This can be done once happen that the shaped element in a corresponding Recess is guided at an angle.
  • Form element assigned an additional wedge drive the one Has wedge surface with an inclined surface on the Form element interacts.
  • the introduction of the force does not necessarily have to be via the tool directly, but can also be used with a Hydraulic component are applied.
  • the best power distribution between the wedge drive and Form element should be guaranteed when the first Sloping surface of the molded element on the riser with the second inclined surface, which with the Wedge surface on the wedge drive cooperates, an angle of 80 ° to 100 ° depending on the length and depth of the embossing includes.
  • a profile is molded into the workpiece a rotating / pushing movement of a corresponding one Form element that on its face the pattern for has the profile.
  • a profile for example a precision toothing 3, molded.
  • This workpiece 1 is between one Bracket 4 and a guide 5 clamped.
  • a recess 6 is provided in the guide 5 by a rising surface 7 an inclined support train for a shaped element 8.
  • This shaped element 8 has in an end face that towards the workpiece 1 is aligned, a pattern 9 of a profile, which the Profile 3 corresponds to that by this pattern 9 in the Workpiece 1 is to be molded.
  • the shaped element 8 has a first inclined surface 10, which on the rising surface 7 slides. At an angle of about 90 ° to this first Inclined surface 10 runs a second inclined surface 11, the in turn cooperates with a wedge drive 12. For this the wedge drive 12 engages the second with a wedge surface 13 Inclined surface 11.
  • the workpiece 1 is between the counter holder 4 and the guide 5 eingklemmt.
  • One of the arrows 14.1 acts as the clamping force and 14.2 labeled vertical force.
  • a thrust 15 is applied to the wedge drive 12, the wedge drive 12 vertically upwards against the workpiece 1 is pushing.
  • the wedge surface 13 presses it Guide element 8 to the right, this on the Rising surface 7 slides so that the pattern 9 in the Can impress workpiece 1 and create profile 3 there. This is done at an acute angle w to the surface 2 of the workpiece 1 down.
  • a profile 3.1 is to be molded into the workpiece 1 by a rotary / pushing movement.
  • a shaped element 8.2 is guided in a corresponding recess 6.1 in the guide 5.2, a corresponding rotary / thrust drive being identified only schematically by 21.
