Abstract

Device for preferably simultaneous forming of several workpieces by means of pressure rollers, projection pressure rollers, compression molding or a combination thereof. The production of several workpieces takes place in that at least two mirror-image arranged axes of rotation, consisting of the workpiece receiving mandrel and the pressure roller receiving Vorsetzer. By relative gegenlaeufiges axial displacement of the axes of rotation, the pressure roller of each contacted an axis with the arranged on the Drueckdorn the other axis workpiece and reduces, for example, the wall thickness. By simultaneous axial and radial displacement of the axes of rotation deviating from the cylindrical shape workpieces can be produced. The essential elements of the invention are shown in FIG. Fig. 1

Title of the invention

Vorriohtung for preferably simultaneous forming of several workpieces by means of pressure rollers, Projektjdrückierwalze ^ fformdrüoken or their combination

field of use

The invention relates to a device for more productive shaping of solid or hollow workpieces, for example shafts, bushes, hollow lead bodies and the like.

Characteristic of the known technical

To increase the productivity, in particular during pressure rolling, several forming tools are engaged simultaneously or staggered in order to increase the forming capacity per workpiece overflow of the tool (for example, Drüokxolle). Known tea-high, production-efficient solutions are, for example, multi-drum devices accommodating magnetic drums

relative to the Werkatüokaohse relatively displaceable Drüokuasohlenneneupporten are arranged or because «Umforjrreriahren Kügeldrtlokwalzen, in which known from the bearing industry balls, the duroh Laufrlnge supported» form a relatively rotating around the spinning mandrel closed ball ring, instead of the Drttokrollen to Eineatz ·

Its own is the rotary forming process that is used, that only one workpiece is produced per process cycle. This method requires a relatively high proportion of tooling auxiliary time per workpiece (for example for the tool pre-overflow, tool backfeed into the starting position, workpiece tension u. ), which is often greater than the actual time required for the forming operation, and thus an increase in the productivity.

The currently practiced method of increasing the productivity of, for example, the Drüokv / alena alone by the use of several forming tools of different modification involved in forming, thereby increasing the rate of advance, entails higher material and financial expenditures which do not always correspond to the productivity achieved "Szuwaohs equivalent to one.

The degree of deformation that can be realized per workpiece overflow is determined, independently of the number of tools involved in the forming process, primarily by the material to be formed and the economically acceptable tool life, including the economically acceptable dimensioning and equipment of the machine required to implement the method, so that the forming capacity is not Due to this constraint, the minimization of process-dependent auxiliary times and the knee-twist of devices serving this purpose are of particular importance as means for increasing the productivity.

Object of the invention

The aim of the invention is the Naohteile the known technical solutions, primarily the relatively high tent share for

manufacturing helpful times to taint ml er en by made several Werkstüoke simultaneously ·

Explanation of the essence of the invention

Erfindungagemäß is the target, preferably at the same time a plurality of workpieces by means DrUokwalzen, Projizierdrüoken, fformdrüoken or duroh produce their combination to daduroh to increase productivity, daduroh achieved _r that otherwise auxiliary times necessary for a workpiece per cycle * are minimized This gesohieht by at least two known rotationally received Werkü tüoke relatively axially (and oh if also require radial) against each other. '

In this case, the axial and radial movement can take place superimposed. The tool (s) respectively arranged directly or indirectly on or at one axis of rotation concentrates with the workpiece arranged on the respective other rotary tube, with the tools move relative to each other relative to the movement of the axes of rotation relative. The required, at least two Aoh3en can be arranged in the spinning machine so that the one axis of the known main modules of a spinning machine, spinning mandrel and Vorsetzer additionally arranged on this Drüokwerkzeug (s) and the other axis of the analog, mirror image on the support arranged assembly (including the drive) is formed · The arrangement of at least two mirror-image arranged from the main assembly spinning mandrel, presetter with zuaätz-Iioh arranged on this Druckwerkseug (s) existing rotating Aohsen, which are relatively mutually displaceable, without the use of the known support, It is also possible · The tool / workpiece contact can start at the same time * or with a delay in time, simultaneously or with a time delay, on at least two workpieces. · In order to minimize the path-dependent auxiliary times, the tool / workpiece contact should preferably be simultaneously b ends ·

When the solution according to the invention is used, those which are otherwise required for a work piece are conditioned by the methods of the invention

Wegabeohnltte or · Zeitanteile for two or more workpieces in Anspruoh taken and thus reduces the epezifisohe Zuitaufwand per Werkstilok «

Preferably, the device according to the invention should be used in the shaping of workpieces which are sufficiently high in their dimensioning in the initial and final states.

Auaführunas example

The invention will be explained in detail naohstehend to two embodiments.

FIGS. 1 and 4 tend to show a possible variant of the inventive solution *

Me Sarstellung according to Figures 3 and 4- shows a variant of the arrangement of several Drüökwerkzeugen in a turret, the operation in principle corresponds to the representation according to the figures 1 and 2 *

On the representation of the known main assemblies presetter 1, spinning mandrel 2, pressure roller 3, turret 5, bearing 6 and turret axis 8 existing device in connection mit.einer this receiving machine has been omitted *

The drum roller 3, received by the yoretter 1, is arranged in a relatively rotating manner with respect to the latter, but is locked against the axial displacement by the stops 7. The angle A between the axes I and II is variable for the variability of the end wall thickness S of the workpiece 4 · On the versatility of the clearance α can be verziohtet when the pressure roller (s) 3 radially adjustable, for example by means of an adjustable eccentric on the presetter 1 is (are) ·

With simultaneous (coordinated) relative axial and radial displacement of the axes of rotation I and II, workpieces deviating from the cylinder can be produced ·

In the exemplary embodiment illustrated in FIG. 3, the spinning roller (s) 3 are received in a turret 5, which is rotationally fixed relative to the spinning mandrel 2. The required rotation of the presetter 1, caused by the spinning mandrel 2, is durably zwisohen the presetter 1 and the turret 5 arranged bearing 6 gesiohert. The device elements shown in Figure 3, Axis II alnd analog mirror image on the axis I arranged.
