- Such a link chain comprises tabs which are arranged in a plurality of rows arranged next to one another in a predetermined pattern in succession with respect to the length direction of the link chain.
- Each tab has a recess, which are penetrated by two pairs of rocker we almost as bolts or pins.
- two adjacent tabs are each hinged together by a pair of Wiegedruck Federationcommunpan as a chain-swing joint.
- Each rocker pair has two rocker links.
- the cradles are based in the longitudinal direction of the link chain each with their sides facing away from each other on the inner edge of the recess of the respective tab on contact surfaces.
- a bending of the link chain is made possible by the fact that the cradles of a chain-type cradle pivot each other.
- the rocker pressure plates roll against one another on the rolling surfaces located on mutually facing sides.
- the present invention has for its object to provide a method for producing a rocker pressure piece and an embossing device for producing a rocker pressure piece and a rocker pressure piece itself, with a relief of the tabs of a plate chain is made possible in the torque transmission.
- the profiling, and thus the thickness, of the weighing element or of the subsequent weighing pressure piece according to the invention can be achieved by the bowing or deformation of the profile wire. change pressure piece along a predetermined section.
- a greater elongation, in particular of the edge flap of a plate-link chain, which advantageously contributes to an increase in the strength, can be made possible by the weighing pressure pieces produced according to the invention.
- the method according to the invention thus produces particularly process-reliable and inexpensive rocker pressure pieces for a link chain.
- crowning of the formed as a rocker pressure piece profile wire other deformation possibilities are used, such. B. by strong stretching a predetermined portion of the profile wire could also be deformed, but encounters this type of deformation limits of process capability.
- the tabs of the tab chains can flow and tear.
- the production in such a deformation is relatively complex and labor intensive.
- the crowning of the profile wire is particularly advantageous in every respect.
- each separated profile wire is formed as a rocker pressure piece with at least one cambered rolling surface for rolling on a corresponding rolling surface of a rocker pressure piece.
- each separated profile wire is formed as a rocker pressure piece with at least one cambered contact surface for engagement with an inner edge of a recess of a tab.

- the wire Profile be taken as a continuous wire from a roll and initially the crowning carried out to perform the cure only after knocking off a certain area of the profile wire.
- the bombing or forming according to the invention is such that a very high precision of the degree of deformation is made possible by a force control. This is in contrast to the usual way controls by stops on forming tools.
- residual stresses are generated in the rocker pressure piece or in the profile wire, which further increases the breaking strength of the rocker pressure piece, similar to how the tab strength increases when the warp is stretched.
- the object according to the invention is also achieved by a stamping device for producing a rocker pressure piece of a chain-type rocker joint from a profile wire.
- a stamping device for producing a rocker pressure piece of a chain-type rocker joint from a profile wire.
- an embossing device in particular for carrying out the aforementioned method is proposed, which comprises a housing having a lower housing half as a die and an upper housing half for guiding a stamping die for crowning the profile wire.
- a previously described rocker pressure piece can be embossed or cambered.
- the lower half of the embossing device according to the invention may comprise a channel or the like, in which the profile wire, for. B. as an endless wire, and can be performed.
- the channel of the lower half of the housing has at least one recess for forming at least one contact surface on the profile wire.
- a plurality of recesses may be provided for bearing surfaces with a fit for guiding the profile wire in the channel.
- the channel may include a clearance or the like for receiving the material displaced by the embossment.
- the clearance may preferably be opposite to the rolling surface to be embossed.
- the upper half of the housing embossing device according to the invention z. B. is aligned approximately perpendicular to the channel Having guide or the like for the die.
- optimum guidance of the embossing punch is achieved when it is pressed down onto the rolling surface to be embossed.
- the embossing stamp itself can have a raised stamp surface with an approximately rectangular basic shape. There are also other structural forms of the stamp surface conceivable.
- the raised punch surface may have a predetermined slope to realize a preferred shape of the surface to be embossed or the rolling surface on the rocker pressure piece.
- the slope may in each case have a gradient from the central mirror axis to the respective edge in only one embossing process, in which the central region is approximately 0.05 to 0.01 mm higher than the one respective edge is arranged.
- the central region is approximately 0.05 to 0.01 mm higher than the one respective edge is arranged.
- the embossing device according to the invention in addition to the continuous feeding of an endless wire profile after embossing comprise a separating device with which a predetermined length of the embossed profile wire as a cradle z. B. is knocked off, so that the individual cradles can be collected in a receptacle. These individual cradles can then be cured together in a particularly simple manner.
- the separation of the profile wire is carried out in each case on the embossed sections.
- the separation or knocking off can take place approximately in the middle, so that an embossed section or a rolling surface is provided at one end of each stamped printing piece.
- the present invention also proposes a rocker pressure piece of a chain-type rocker joint for a link chain, in particular for a CVT link chain.
- the weighing pressure piece according to the invention may be provided as a chain-type pivot joint in a recess of a tab of the plate-link chain or penetrate this recess.
- Two cradles form a cradle pair as chain cradles.
- the opposite back sides of the rocker pressure pieces of the rocker pressure piece pair form the bearing surfaces for abutment with the inner edge of the recess, wherein on the mutually facing sides of the rocker pressure pieces of the rocker pressure pair additionally rolling surfaces are provided for mutual rolling.
- At least one of these rolling surfaces of each weighing pressure piece is cambered in order to achieve the advantages described above.
- the relative thickness between the cambered rolling surface and a contact surface of the rocker pressure piece is changed or reduced in the longitudinal direction.
- Figure 1 is a schematic view of a possible embodiment of an embossing device according to the invention for carrying out a method for producing a weighing pressure piece.
- FIG. 2 shows a three-dimensional partial view of the embossing device for producing the weighing-pressure piece
