Definitions
- the invention relates to a pressing tongs for pressing pipe connections, in particular for pipes made of composite materials, into an embodiment according to the preamble of claim 1.
- Known pressing tongs of this type (DE 27 25 280 A1) have a two-part mold insert, in which the parts of the mold insert extend over a central angle of 180 °.
- the parting line between the two molded parts coincides with the longitudinal center plane of the pressing tongs, to which the two pivot axes for the pressing jaws are arranged in mirror image.
- the invention has for its object to provide a pressing tongs of the type mentioned, in which the molded parts act more uniformly on the parts of the pipe connection to be pressed and provide pressed pipe connections with particularly high dimensional accuracy.
- the invention solves this problem by pressing tongs with the features of claim 1. With regard to further essential configurations, reference is made to claims 2 to 10.
- the pressing tongs according to the invention produce pressed pipe connections, in particular with a circular basic shape are particularly accurate.
- the forces used for pressing through the molded parts are better distributed over the circumference into the parts of the pipe connection, with the result that, while avoiding crushing of the material and the associated damage to the material structure, clean shaping takes place with a largely radial orientation of the forces acting.
- the pressing tongs illustrated in the drawing for the pressing of pipe connections, in particular for pipes made of composite materials, comprise two pressing jaws 1, 2 which are connected to one another by connecting plates 3, 4 arranged on both sides and can be pivoted in opposite directions about the parallel pivot axes 5, 6 on the connecting plates 3 , 4 are supported.
- the pressing tongs also include a mold insert 7, which is formed by three molded parts 8, 9, 10, which together define a molded opening 11 in the closed position.
- One molded part 8, 9 is assigned to a pressing jaw 1, 2, and the third molded part 10 is supported in a stationary manner between the connecting plates 3, 4 of the pressing tongs.
- the stationary third molded part (10) has a symmetrical arrangement with respect to the longitudinal center plane 12 of the pressing tongs and has a central angle which is either the same as the central angle of the two movable molded parts 8, 9 or larger than their central angle, which is particularly the case with pipe connections with larger outer diameters can be advantageous.
- the pivot axes 5, 6 are advantageously above an imaginary extension 13, 14 of the parting plane 15, 16 between two adjacent molded parts 8, 10 and 9, 10, respectively, in order to improve the central alignment of the pressing forces which the molded parts 8, 9 and therefrom derived the molded part 10 when closing the pressing tongs on the parts of the pipe joint.
- the pivot axes 5, 6 have a mirror image orientation to the longitudinal center plane 12 of the pressing tongs, and they are defined by a hinge pin 17 or 18, which, as is illustrated for the hinge pin 17 in FIG. 7, the associated press jaws 1 and 2 and passes through both connecting plates 3, 4 and is secured by retaining screws 19, 20.
- the two press jaws 1, 2 are prestressed in the closing direction by a spring 21, for example a helical compression spring, which is supported between the stationary molded part 10, so that after the pressing tongs have been placed on the parts of the pipe connection to be pressed, the pressing tongs on these parts Self-hold can be obtained and released in order to be able to connect a tong drive device (not shown) by means of an aligned bores 22, 23 in the cross bolt that extends through the connecting plates 3, 4.
- a tong drive device can have a hydraulic or pneumatic or other suitable drive for fork parts, which the reach behind the free ends of the press jaws 1, 2 and swivel in the opposite direction outwards.
- a guide plate 26, 27 is provided for parts of the pipe connection, which is indicated in FIG. 4 in dashed or dash-dotted lines and a support sleeve 28 with centering groove 28 'in a centering area, a compression sleeve 29 and comprises a tube 30 which can be made of plastic, a metallic material or preferably also of composite materials such as aluminum and cross-linked polyethylene.
- Both guide parts 26, 27 have the shape of a fork-shaped plate and, between their fork legs, a shaped recess 31, 32, each adapted to a part of the pipe connection.
- the shaped recesses 31, 32 of both guide parts 26, 27 can be identical to one another, so that the pressing tongs can be brought into engagement with the parts of the pressing connection independently of the side. In the case of the press connection shown in FIG. 4, this presupposes that the diameter of the bottom of the groove 28 and the outer diameter of the tube 30 are identical to one another.
- the shaped recesses 31, 32 can, however, also be designed differently in such a way that the shaped recess 32 is adapted to the groove 28 'of the support sleeve 28 and the shaped recess 31 to the circumference of the tube 30 if these have different dimensions.
- the guide parts 26, 27 are preferably fixed by means of retaining screws 35, 36 (FIG. 6) so that they can be detached and exchanged for spare parts or guide parts with other recesses.
- the interchangeability is also given for the molded parts 8,9,10, which are also releasably fixed by screws.
- the screws 35, 36 fix the fixed molded part 10, and the molded parts 8, 9 are fixed by means of screws on the press jaws 1, 2, of which that is illustrated for the molded part 8 and is designated by 38.
