In such a case the toothing is normally applied by fine pressing.

Fine blanking finds various and beneficial applications in the following sectors:

The snap rings with the inside-located spring supports can be made cheaply by means of precision stamping and subsequent hardening.

This is preferably accomplished by fine punching.

This known solution is above all used for forging machines but cannot be applied to fineblanking.

The displacement pressure P 2 acting on the counterforce ram is effectively hydraulically balanced with the pressure generated in the second accumulator 19 and can take on values varying between cushion pressure and the pressure PU necessary for forming or fineblanking.

Given this prior art, the basic object of the invention is to provide a method and a device for controlling the synchronization of cylinder/piston units and at least one main ram and for reducing pressure peaks during forming and/or fineblanking on fineblanking or stamping presses, which discharges any recoil caused by the impact between the punch and the workpiece, independently of quantity, from the controlling of the working pressure of the hydraulic fluid, bringing about a marked improvement in the synchronization properties of the cylinder/piston units and the main ram through a constant pressure characteristic in the hydraulic system including with high cycle times and speeds.

For manufacturing of depressed portions which have teeth and are of one piece with the hinge part itself, the depressions may be formed by fine stamping from a flat sheet blank, and the fine stamping of the depressions is performed simultaneously and together with the annular groove in the region of the teeth feet in the same working step. Thereby the material displaced from the annular grooves forcibly flows to the teeth tips and the stamping indentations which otherwise would take place in the teeth tip region are considerably reduced.

Another special factor in this project involved supervising the entire tool construction process for all required components (plastic injection moulding, precision-stamping the knives and matrices, aluminium die casting, and press-bent parts).

The invention relates to a method for predicting and/or determining the rollover for a part generated by virtual fine blanking, in which a digital image, in particular the cutting contour of the part, is generated, provided as an image file and subjected to image analysis in an image processing device.

The invention relates to a method for controlling the synchronization of cylinder/piston units for counterforce rams and/or vee rings and for reducing pressure peaks during the fineblanking and/or forming of workpieces on a fineblanking or stamping press equipped with at least one tool, in which the cylinder/piston unit is subjected to the control pressure of a hydraulic fluid and the press ram is driven mechanically or hydraulically.

This enables separately removing the occurring during fine blanking or the like slugs and at the same time position oriented removing the fine blanking parts, what contributes to further raise the removing productivity.

For the purpose of feeding the liquid via the inlet into the medium inside the container as well as for discharging the solution toward the outlet, distributing and collecting openings are provided in the supporting element 5; the collecting openings for the prepared solution 9 may be arranged in the supporting element 5 slightly above (upstream of) the actual outlet 8 in the form of slits and can be produced by laser cutting processes or fine blanking, for example.

The lighting unit according to claim 1, wherein the apertures (50) in the diaphragm element are manufactured by blanking or laser cutting.

The post-processing is for example a fine blanking or a different way of shaping the data carrier so that the desired final shape is obtained.

In contrast to direct fine blanking of chain link plates, pre-punching and subsequent profiling enables the punch sections to be punched out comparatively fast with a comparable smooth-cut region.

Accordingly, it is important for such high performance chains that the functional surfaces in the region of the tooth flanks, plates, rear surfaces and pin openings exhibit low surface roughness, which can generally only be achieved by profiling or fine blanking.

Toothed chains are used in automotive drives in addition to simple non-toothed bush or roller chains, where the tooth contour of the toothed plates as a functional surface is also subjected to a profiling process or fine blanking.

Conventional seat adjustment components, for example, fixed and swiveling hinge parts of hinge attachments, are produced by forming, fine blanking or stamping with the necessary high dimensional accuracy for their final use (see, for example, EP 0 694 434 B1, DE 32 44 399 C2, DE 28 34 492 C2, DE 32 27 222 C1).

Conventionally, seat adjustment components, for example, fixed and swivelling hinge parts of hinge attachments, are produced by forming, fine blanking or stamping, with the necessary high dimensional accuracy for their final intended use.

By precision stamping the connector pins, it is advantageously achieved that the connecting pin end faces have the surface quality that is required for wire bonding.

The latter method is used when the parts 1, 2 3 a, 3 b are made with a relatively high degree of accuracy, such as for example by precision blanking, deep drawing or solid forming.
