Definitions

the present invention relates to a pressing tool having two pressing jaw halves extending in the longitudinal direction from a rear end to a front end, which are hinged together and can be brought from an open position to a closed position, wherein the pressing jaw halves each have an inlet contour at the rear end, wherein the inlet contours cooperate with a movable part of a pressing contour such that the movable part of the pressing contour, as it is displaced in the longitudinal direction towards the front end of the pressing jaw halves, moves along the inlet contours and pushes them apart to the pressing jaw halves from the open position to the closed position bring.
the press tools serve to enclose a specific area of the fitting with a press jaw after the pipe end has been inserted into the fitting. Subsequently, to create the cold connection, the enclosed areas, for example a bead and the parts adjacent to the bead, of the fitting are pressed together by closing the press jaw so that the fitting and the pipe deform in the area of the press jaw.
a press jaw with press contour with two extending in the longitudinal direction from a rear end to a front end die jaw halves is for example from the EP 1 095 739 B1 known.
the two die jaw halves are hingedly connected to each other, as a rule over transverse to the longitudinal direction extending bridge parts, at one end of which a die jaw half is rotatably mounted and at the other end the other die jaw half is rotatably mounted.
the two pressing jaw halves form a pressing jaw which can be brought from an open position into a closed position in order to non-detachably connect the fitting to the pipe end by cold deformation.
each an inlet contour is provided, wherein the two inlet contours in the open position of the pressing jaw touch.
the inlet contours interact with the pressing contour, the movable part of which generally has rollers, in such a way that the moving part of the pressing contour, when displaced longitudinally towards the front end of the pressing jaw halves, moves along the inlet contours and pushes them apart.
a non-moving part of the pressing contour is firmly connected to the bridge parts. The farther the rollers press the inlet contours of the two pressing jaw halves apart, the more the press jaw closes up to the closed position of the pressing jaw.
the DE 42 40 427 C1 also known for large diameters pressing tools in which the press jaw is formed from a ring of hingedly interconnected chain links.
the individual members of such a press chain can be unfolded to accommodate the fitting.
the chain links for example by means of a separate electro-hydraulic locking device, closed again or moved together to close the press jaw. Due to the elaborate technology is a such press tool but relatively expensive.
the folding of the press chain around the section of the fitting to be pressed is relatively time-consuming.
each pressing jaw half has at least one recess and at least one projection in the region of its inlet contour, the projection of one pressing jaw half lying opposite the depression of the other pressing jaw half.
the two pressing jaw halves are identical parts, ie components of the same shape and dimensions.
a pressing tool can be used, which has almost the same structure as the pressing tools, which are used for nominal widths up to 54 mm, so a relatively simple design press tool.
a possibility is created to increase the opening angle of the press jaw by the rear ends of the pressing jaw halves, where the inlet contours are provided, in the open position of the pressing tool even further to each other can be moved.
the profile of the inlet contours, along which the movable part of the pressing contour moves along in order to bring about closure of the pressing jaw does not change with respect to the known pressing tool.
the same pressing contours can still be used for the pressing tool according to the invention, despite an altered rear end of the pressing jaw halves and an associated larger opening angle, in order to actuate the pressing jaw.
the inlet contours so the outer surface of the rear pressing jaw end, remain unchanged from the prior art and at the same time allows the two rear ends of the pressing jaw halves dive into each other or intermesh. The deeper the depressions are provided at the rear end of the pressing jaw halves, the larger becomes the opening angle of the pressing jaw at the same inlet contour.
the recess and / or the projection is in each case elongated and extends in particular in the longitudinal direction of the pressing jaw halves.
the width, height and / or length of the recess corresponds to the width, height or length of the respectively opposite projection.
the dimensions of the projection should be chosen so that the projection on the one hand easily fits into the opposite depression, without requiring, for example, a greater effort would be necessary, and on the other hand, the projection is so wide and so stable that the pressing contour can slide along it and transmit a large force.
the pressing tool engage in the open position of the pressing jaw halves of the projection and the recess, each opposite, completely into each other. In this way, at the same time an optimal lateral guidance of the pressing jaw halves is achieved at the rear end of the pressing jaw halves in the open position with the press jaw open.
each pressing jaw half preferably has the same number of depressions and / or projections. It has proved to be advantageous if each pressing jaw half each has a recess and a projection or two recesses and two projections.
the first variant is particularly easy to manufacture and the latter variant enables optimized power transmission from the pressing contour to the inlet contours.
the movable part of the pressing contour is formed such that it comes into contact only with the projections of the pressing jaw halves. But there are also more complex pressing contours conceivable, immerse the moving part in the wells and thus the Force can transmit not only on the projections, but also on the depressions on the die halves.
the movable part of the pressing contour rollers which can roll along the projections.
Fig. 1 shows a section through a conventional pressing tool 1 with a pressing jaw, which is suitable for press connections, in which the nominal diameter of the pipe end, which is guided into the fitting, can be up to 54 mm.
the pressing tool has two longitudinally extending from a rear end to a front end pressing jaw halves 2, which are hinged together, in such a way that each of the pressing jaw halves 2 is rotatably mounted on bridge parts 3 via bolts 4, wherein the bridge parts 3, from in which only the rear is shown in Fig. 1, represent the connection of the pressing jaw halves 2.
the conventional pressing tool 1 or the pressing jaw halves 2 can be moved from an open position in which the pressing jaw is maximally open into a closed position in which the pressing jaw is closed and a pressing force can be exerted on a fitting.
At the rear end of the two pressing jaw halves 2 each have an inlet contour 5 is provided, which cooperate with a movable part of a pressing contour 6, in particular with the rollers 7 of the pressing contour 6, as follows.
the inlet contours 5 of the respective pressing jaw halves 2 touch each other in a section and thereby limit the maximum opening angle of the press jaw.
the movable part of the pressing contour 6 is now displaced in the longitudinal direction towards the front end of the pressing jaw halves 2, the non-movable part of the pressing contour 6 being fixedly connected to the bridge parts 3, then the rollers 7 move along the Inlet contours 5 and push them apart. Since the pressing jaw halves 2 are connected to one another in an articulated manner via the bridge parts 3 and the bolts 4, the pressing jaw is correspondingly closed until finally the closed position is reached.
a fitting 8 is shown schematically, are inserted into the tubes of a nominal diameter greater than 54 mm. It becomes clear that despite maximum opening of the press jaw, the fitting 8 can not be inserted between the press jaw halves 2 because its diameter is too large.
Fig. 2 now shows a sectional view of a first embodiment of a pressing tool 1 according to the present invention.
the pressing tool is constructed similar to the pressing tool 1 described above with reference to FIG.
two pressing jaw halves 2 are articulated to one another via bridge parts 3 and bolts 4 and have at their front end a pressing jaw and at their rear end inlet contours 5 which interact with a movable part of a pressing contour 6 via rollers 7.
FIG. 2 It can be clearly seen from FIG. 2 that a fitting 8 of the same size, as shown in FIG. 1, can be introduced without difficulty into the press jaw of the press tool according to the invention, since in the open position, compared to the prior art, a larger maximum opening angle is reached.
each pressing jaw half 2 in the region of its inlet contour. 5 Recesses 9 and projections 10, wherein the projections 10 of a pressing jaw half opposite the recesses 9 of the other die jaw half.
Fig. 3 a three-dimensional view of the pressing jaw of the embodiment of Fig. 2 is shown.
the opposite recesses 9 and projections 10 can be clearly seen in the region of the inlet contours 5.
two depressions 9 and two projections 10 are provided in the region of each inlet contour 5.
the recesses 9 and the projections 10 are each elongated and extend in the longitudinal direction of the pressing jaw halves 2.
the width, height and length of the recesses 9 correspond exactly to the width, the height and the length of the respective opposite projections 10. In this way In the open position of the pressing jaw halves 2, which is shown in FIG. 3, the recesses 9 and the projections 10, which lie opposite one another, can completely engage one another.
the closed position in which the maximum pressing action is achieved, is now shown in FIG. 4 for the above-described embodiment according to the invention.
the closed position is achieved in that the rollers 7 (not shown) are moved along the inlet contours 5 in the direction of the front end of the pressing jaw halves 2, whereby the pressing jaw halves 2 pressed apart in the region of its rear end and in the region of its front end, where in the present case the press jaw is provided to be compressed.
the rollers 7 of the pressing contour 6 on the outer surface of the rear end of the pressing jaw halves 2, which here forms a portion of the inlet contour 5, are moved along.
the inlet contour 5 is formed by different sections, namely first by a flat portion 11a, in which no depressions are provided, followed by a portion formed by the projections 10 11b, to which finally an end portion 11c adjacent, which also no depressions having. In the region of the portion 11 b formed by the projections 10 grooves are milled, which form the recesses 9.
the pressing force is thus on the rollers 7 of the pressing contour 6 in the sections 11 a and 11 c of the inlet contours 5 on the Whole width of the pressing jaw halves 2 transferred to this, whereas in the section 11 b, the power transmission takes place only on the projections 10.
FIG. Fig. 5 shows the pressing jaw, so the two articulated pressing jaw halves 2, in the same view as Fig. 4, that is in three-dimensional view in the closed position.
