Definitions
- the pressing tool comprises a plurality of pressing jaws arranged around a press axi
- Support structure elements associated mating surface arrangements.
- Such radial presses are known in various constructions, for example as yoke presses, in which the two structural elements designed as press yokes are movable relative to one another in a plane perpendicular to the press axis (cf., for example, DE 4135465 A1, which is herewith incorporated by reference in its entirety into the content of the present application is made), or as a hollow piston press or printing plate press, in which the two structural elements are movable parallel to the press axis relative to each other, (see, for example, DE
- the known generic radial presses have proven themselves in practice and generally satisfy the demands placed on them. Nevertheless, the present invention aims to further improve generic radial presses in the sense that the precision of the workpiece produced is further increased, in particular by a further improved reproducibility and dimensional accuracy.
- the above-mentioned object is achieved in that at radial presses of the type specified at least in each case one of the cooperating sliding and mating surface arrangements, the load-bearing support of the pressing jaws on the respective structural element in two spaced-apart areas, between which a in the sliding direction of the respective pressing jaw relative to the associated structural element extending free space without load-bearing function, wherein in the two load-bearing areas of the respective cooperating sliding and mating surface arrangements, the identical sliding plane consists.
- a first preferred development of the present invention is characterized in that the free spaces are each formed by recesses provided on the pressing jaws in the region of the sliding surface arrangements and extending in the sliding direction of the relevant pressing jaw relative to the associated structural element which define at the respective sliding surface arrangement two spatially separated, mutually spaced, co-planar sliding surface sections, between which the associated recess extends.
- said clearances can each be formed by recesses provided on the sliding elements - resting on the relevant structural element - and in the sliding direction extend the respective pressing jaw relative to the associated structural element, wherein on both sides of the recesses load-carrying regions exist, which abut both on the structural element as well as on the respective pressing jaw.
- said recesses may be respectively provided on the side of the sliding plate, with which this rests on the respective structural element, or on the opposite, the pressing jaw opposite side of the sliding plate or else on both sides of the sliding plate.
- the free spaces provided according to the invention can, moreover, in the sense of yet another development of the present invention, also be provided by recesses provided on the structural element in the area of the counter-surface arrangements, extending in the sliding direction of the respective pressing jaw relative to the structural element, which recesses lie against the respective mating surface arrangement define two spatially separated, spaced apart coplanar mating surface portions between which the associated recess extends.
- the recesses delimit and respectively delimit the two coplanar load-bearing regions from each other on the cooperating sliding and counter-surface arrangements, both on the pressing jaws and on the structural elements, are provided both on the pressing jaws and on possible sliding plates or on both the structural elements and on possible sliding plates.
- the transverse to the sliding direction of the respective pressing jaw relative to the associated
- Structural element determined width of the free spaces at least 15% of the sum of the widths of the two load-bearing areas. In typical applications, it is particularly advantageous if the width of the free spaces in this sense corresponds to at least 35% of the sum of the widths of the two load-bearing areas. In certain constellations, it may even prove expedient that the width of the free spaces corresponds to at least 50% of the sum of the widths of the two load-bearing areas.
- FIG. 1 shows a sliding plate of a radial press according to the invention, designed as a hollow piston press with the in
- Fig. 1 in the present only relevant portion radial press corresponds in terms of their structure, apart from the deviations explained below, described in DE 4135465 AI, executed in the form of a yoke press radial press.
- full reference is made to the corresponding publication which, by reference, fully relates to the content of the present application. makes, in particular their Fig. 2 together with related explanation.
- the two relatively movable (double arrow A) structural elements 1 and 2 are formed by the lower press yoke 3 and the upper press yoke 4.
- the pressing tool 5 is received, which has eight about the press axis 6 arranged around pressing jaws , While a press jaw 7 fixed in position in the lower press yoke 4 and a further pressing jaw eighth
- two pressing jaws 9 are slidingly supported on the press yokes 3 and 4 from.
- the two respective pressing jaws 9 each have two sliding surface arrangements 10, which are slidably supported on corresponding counter-surface arrangements 11.
- the counter-surface arrangements 11 are defined by the surface of sliding plates 12, which are received in a fixed position in the lower press yoke 4 and the upper press yoke 3.
- the sliding plates 12 are not the entire surface of the lower press yoke 4 and the upper press yoke 3 at. Rather, they lie on two spatially by a free space F forming recess 13 from each other and spaced apart areas 14 on the lower press yoke 4 and the upper press yoke 3, wherein only in the respective areas in which the sliding plate 13 on the respectively associated Press yoke rests and is supported, a load transfer from the press jaws 9 in which the structural elements 1 and 2 performing press yokes 3 and 4 takes place.
- Fig. 3 illustrates how the present invention can be implemented in such a type of radial press, wherein two different variants are illustrated. So can the at the
- Pressing jaw 15 provided sliding surface arrangement 16 by means of the (a free space F forming) recess 17 are divided into two spaced Gleitdon Schemee 18 in which the pressing jaw 15 is supported on the sliding plate 19, on which the counter-surface arrangement 31 is executed on the relevant structural element of the radial press ,
- the pressing jaw 15 is supported on the sliding plate 19, on which the counter-surface arrangement 31 is executed on the relevant structural element of the radial press
- the support of the pressing jaw 15 on the associated structural element can be realized in two spatially separated, mutually spaced regions, in that the sliding plate 21 has a (again a clearance F forming) recess 22, so that the sliding surface arrangement 20 of the pressing jaw 15 on a two-part, two mating surface portions 30 facing counter surface arrangement 23 of the sliding plate 21 slidably rests.
- the present invention can be realized in a technical-constructive manner in that the sliding plates 24 have a clearance 25 forming a free space F, which comprises the
