Definitions
- the invention relates to a press tool for connecting workpieces, with a press ring made of press jaw elements which are connected to one another in an articulated manner, the press tool being open at at least one closing point between two press jaw elements and having engagement points there for a closing device with which the press jaw elements can be brought together to form a closed ring.
- sleeve-shaped press fittings which are plastically deformable and consist of metal, preferably of steel. Their inner diameter is so much larger than the outer diameter of the pipe ends to be connected that they are permanently deformed when they are pressed radially against the outer surface of the pipe ends.
- Such pipe connections and the associated press fittings can be found, for example, in DE-C1 187 870 ⁇ and DE-C-40 ⁇ 12 50 ⁇ 4.
- These pressing tools have a pressing ring which is open at a closing point and which is composed of pressing jaw elements which are connected to one another in an articulated manner and which in turn consist of a pressing jaw carrier and pressing jaws which are movably guided in the circumferential direction.
- a press ring can be placed around the point to be pressed in a cuff-like manner and then pulled together with the aid of a closing device.
- the locking device can be permanently connected to the press ring.
- the compression ring is intended and dimensioned for the compression of larger pipe diameters, it is more advantageous for weight and handling reasons to design the locking device as a separate unit from the compression ring, which can be attached to the compression ring placed over the compression fitting in the area of the locking point, and in fact at points of attack provided for this purpose and adapted to the locking device on both pressing jaw elements adjacent to the locking point.
- the area of application of such pressing tools is to be expanded to even larger pipe diameters.
- the press ring then becomes so heavy that handling and safety problems arise when it is folded around the pipe end or around the press fitting.
- the invention is therefore based on the object of designing a press tool of the type mentioned in such a way that the handling of the press tool is facilitated in particular when it is dimensioned for larger pipe diameters.
- At least one coupling member is provided, with which the pressing jaw elements adjacent to the closing point (s) can be provisionally connected, the coupling member being designed to be flexible in the closing direction in the coupled state.
- the press ring after it has been placed around the pipe end or the press fitting, can be provisionally secured by bridging the open closing point with the aid of a coupling member and thus closing the press ring.
- the press ring can then no longer slip, and it is no longer necessary to hold the press ring in place for the closing device to be attached.
- the coupling member is designed to be flexible in the closing direction according to the invention, while it limits the mobility of the pressing jaw elements in the opening direction.
- the coupling member can be dimensioned such that the press ring can still be rotated around the workpiece.
- the coupling member is dimensioned such that a circumferential force is applied to the pressing ring when it is placed around the workpiece and when the coupling member is closed, so that the pressing ring is pretensioned on the workpiece to be pressed , in particular the press fitting, is present, so that the press ring can at least no longer rotate automatically.
- the coupling member can have a first coupling lug articulated to the one pressing jaw element and a second one to the other Compression jaw element connected coupling plate, wherein both coupling plates are articulated to each other, for example, via a coupling bolt encompassing both coupling plates.
- a coupling member limits the mobility of the pressing jaw elements in the opening direction, but can articulate outwards during the pressing process with the aid of the closing device, without opposing the closing device in this case with any significant resistance.
- the coupling bolt has a first bolt section which surrounds the first coupling plate and a second, in the second coupling tab has a graspable bolt section, the axes of the bolt sections being offset from one another.
- the second bolt section thus forms an eccentric.
- the length of the coupling tabs and the size of the offset of the axes of the bolt sections of the coupling bolt in relation to the circumferential extent of the locking point should be coordinated accordingly.
- it is expediently connected to a lever.
- the coupling pin should be captively guided in one of the coupling lugs.
- the coupling straps are connected to the associated press jaw elements via hinge bolts and that recesses are provided in the region of the hinge bolts, can reach behind the locking elements of the locking device.
- hinge pins simultaneously form the points of attack for the locking device.
- At least one clamping device for contact with the inserted workpiece is attached to one side of the press ring, the clamping device (s) being able to have, for example, spring elements under spring tension.
- the clamping devices are then in contact with the inserted workpiece, so that the workpiece that has been pushed over cannot slip off. This facilitates assembly, particularly in the case of vertical or inclined pipelines, and at the same time serves to axially secure the two workpieces which are plugged into one another.
- the press tool according to the invention is not limited to the formation of the press ring with only one open closed position.
- the pressing tool is intended for the pressing of large pipe diameters and is dimensioned accordingly in order to adapt it, it can be advantageous if the pressing ring has more than one closing point and a coupling member designed according to the invention is provided for each closing point.
- This training enables the compression ring to be made from individual elements only on site, i.e. in the area of the pipe ends to be connected or even when the compression ring is folded around the pipe end one after the other. It is not excluded to provide a closing point that can be bridged with a coupling member even between all the pressing jaw elements.
- the contraction of the press ring and thus the pressing of the pipe end with the press fitting can be done one after the other in such a way that the closing points are pulled together one by one with the help of the locking device.
- one of the Number of locking points corresponding number of locking devices set and then the locking points are pulled together synchronously.
- the same can also be achieved in that the pressing jaw elements are connected to one another outside the closing point (s) via removable hinge pins, because even then the pressing ring can be gradually assembled on site.
- the pressing elements can also be connected there by means of intermediate pieces, to which the respectively adjacent pressing jaws are articulated by means of pivot pins, at least one of the pivot pins being removable per intermediate piece.
- the pressing jaw elements each consist of a pressing jaw and a pressing jaw carrier, the pressing jaw in each case being displaceably mounted in the circumferential direction in the pressing jaw carrier and the coupling member or members being seated on the pressing jaw carriers and the pressing jaw carriers being connected to one another in an articulated manner.
- the coupling member (s) can also be arranged directly on the press jaws.
- the press ring (5) has essentially identical press jaw elements (6, 7, 8, 9, 10ildete), each press jaw element (6, 7, 8, 9, 10 ⁇ ) consisting of an external press jaw carrier (11, 12, 13, 14, 15) and an inner, arc-shaped press jaw (16, 17, 18, 19, 20 ⁇ ).
- the press jaw supports are connected to one another via intermediate pieces (21, 22, 23, 24), the press jaw supports (11, 12, 13, 14, 15) using articulated bolts (26, 27, 28, 29, 30 ⁇ , 31, 32, 33) are articulated on the intermediate pieces (21, 22, 23, 24).
- At least one hinge pin (26, 27, 28, 29, 30 ⁇ , 31, 32, 33) per intermediate piece (21, 22, 23, 24) is designed to be removable, so that the press ring (5) is divided into individual press jaw elements (6, 7, 8, 9, 10 ⁇ ) can be taken apart or assembled on site.
- the press jaws (16, 17, 18, 19, 20 ⁇ ) are slidably mounted in the circumferential direction in the press jaw carriers (11, 12, 13, 14, 15).
- a clamping device (34, 35, 36, 37, 38) is attached to each press jaw support (11, 12, 13, 14, 15), which has a clamping punch (39, 40 ⁇ , 41, 42, 43).
- the clamping devices (34, 35, 36, 37, 38) also serve to axially guide the press jaws (16, 17, 18, 19, 20 ⁇ ).
- the hinge pins (29, 30 ⁇ ) on the central press jaw support (13) carry a jaw-like jig (44) in the form of a sheet metal part with a semicircular recess (45), the radius of the recess (45) being such that the jig (44 ) fits on the one hand over the pipe end (1), but on the other hand does not fit over the cylindrical part of the press fitting (2) adjoining the annular bead (3).
- This ensures that the press ring (5) can only be placed around the combination of pipe end (1) and press fitting (2) in one position.
- the lower press jaw elements (6, 10 ⁇ ) have between them a closing gap (46) in the positions shown in Figures (1) and (2).
- a closing gap (46) in the positions shown in Figures (1) and (2).
- the free ends of the pressing jaw elements (6, 10 ⁇ ) delimiting the closing gap (46) carry hinge pins (47, 48), a coupling bracket (49, 50 ⁇ ) being suspended from each hinge pin (47, 48).
- the shape of the coupling tabs (49, 50 ⁇ ) and their connection with the hinge pins (47, 48) result in particular from the sectional views according to Figures (3) and (4).
- the free ends of the coupling tabs (49, 50 ⁇ ) have through holes (51, 52).
- a coupling pin (53) is inserted axially. It has a first bolt section (54) with which it passes through the through hole (51).
- One end of the first pin section (54) is with a hand lever (55) connected.
- a second pin section (56) is formed, the axis of which is offset by an eccentricity (57) with respect to the axis of the first pin section (54).
- the second bolt section (56) fits into the through hole (52) of the other coupling bracket (50 ⁇ ).
- the coupling tabs (49, 50 ⁇ ) together with the coupling bolt (53) form a coupling member for the temporary connection of the ends of the press ring (5) before the actual pressing process.
- the press ring (5) is first placed over the pipe end (1) and the press fitting (2), as can be seen from Figure (1).
- the two lower press jaw elements (6, 10 ⁇ ) are pivoted towards each other and onto the pipe end (1), so that they correspond to those shown in Figure (2 ) assume the position shown.
- the coupling straps (49, 50 ⁇ ) which then still hang down and are shown in dash-dot lines in this position in FIG.
- the pivoting of the coupling tabs (49, 50 ⁇ ) happens to a position where they overlap and the through holes (51, 52) merge into one another.
- the coupling bolt (53) and thus the hand lever (55) are in such a position that the second bolt section (56) is offset in the direction of the other coupling plate (50 ⁇ ) and therefore easily in its through bore (52) by axial displacement of the coupling pin (53) and so that both coupling plates (49, 50,) can couple.
- the press ring (5) still has a certain amount of slack.
- the hand lever (55) is then pivoted from the position shown in solid lines in Figure (2) to the dash-dotted position in the direction of arrow E by 180 °.
- the second pin section (56) executes an eccentric movement and thereby shortens the distance between the two hinge pins (47, 48) by twice the eccentricity (57).
- Figures (3) and (4) with Figure (4) showing the pivoted position.
- a circumferential force is applied to the press ring (5) via which the press jaws (16, 17, 18, 19, 20 ⁇ ) press onto the press fitting (2) with a certain radial preload.
- the press ring (5) then has a seat that is difficult or difficult to turn. This effect is supported by the clamping rams (39, 40 ⁇ , 41, 42, 43), which then rest against the pipe end (1) with a radially directed prestress and in this way ensure an axial fixation between the pipe end (1) and press fitting (2).
- a locking device belonging to the pressing tool is used, as is known schematically from FIG. (7) of EP-AO 451 80 ⁇ 6.
- This locking device has two pincer-shaped lever arms with which the locking device can be attached to the hinge pins (47, 48). They cover gaps (58, 59) or (60 ⁇ , 61) and then lay on the outside of the hinge pin (47, 48). The pliers-like lever arms are then moved together by means of a hydraulic motor belonging to the locking device, so that the hinge pins (47, 48) approach each other.
- the press ring (5) assumes the position shown in FIG. (4). After axial displacement of the coupling pin (53) in such a way that the second pin section (56) moves out of the through hole (52), the press ring (5) can be removed again and used for further pressing processes.
- FIG. (6) shows a pressing tool (62) which is somewhat modified compared to the previously described embodiment.
- the structure is basically the same as in the pressing tool (4) according to the figures (1) to (5), so that in the figure (6) parts that correspond to those in the pressing tool according to the figures (1) to (5) , are provided with the same reference numbers. For the description thereof, reference is made to the description of the first exemplary embodiment.
- the pressing ring (63) of the pressing tool (62) shown in FIG. (6) has no clamping devices, but only guide plates 64, 65, 66, 67) in the same place.
- the pressing jaw carriers (11, 12, 13, 14, 15) are not connected here by intermediate pieces, but rather each via pairs of coupling plates (68, 69) or (70 ⁇ , 71) or (72, 73) or (74 , 75) which are articulated on the hinge pins (26, 27, 28, 29, 30 ⁇ , 31, 32, 33) and are connected to one another via coupling pins (76, 77, 78, 79).
- the design of the coupling plates (68, 69, 70 ⁇ , 71, 72, 73, 74, 75) and the coupling bolts (76, 77, 78, 79) is identical to that of the coupling plates (49, 50 ⁇ ) and the coupling bolt (53) .
- the press ring (63) is shown in a position in which the end faces of the press jaws (16, 17, 18, 19, 20 ⁇ ) abut one another and which the press ring (63) assumes after a pressing process.
- the press ring (63) can be Disassemble the pairs of coupling tabs (68, 69) or (70 ⁇ , 71) or (72, 73) or (74, 75) into the five press jaw elements (7, 8, 9, 10 ⁇ ).
- the subsequent pressing process can be done in two ways.
- five locking devices can be attached to the pairs of hinge pins (26, 27) or (28, 29) or (30 ⁇ , 31) or (32, 33) or (49, 50 ⁇ ) at the same time, so that the Distances between the press jaws (16, 17, 18, 19, 20 ⁇ ) can be shortened simultaneously when the locking devices are operated synchronously until mutual contact.
- there is the possibility to carry out the pressing process only with a locking device in that the locking device successively on the pairs of hinge pins (26, 27) or (28, 29) or (30 ⁇ , 31) or (32, 33) or . (47, 48) and then pull them together until the position of all press jaw elements (6, 7, 8, 9, 10 ⁇ ) shown in Figure (6) is reached.
