Abstract
A press tool for joining workpieces has a wraparound ring consisting of hinged clamping components, in which the press tool is open at at least one closing point between the clamping components and has grips at that position for a closing device by means of which the clamping components can be brought together to form a closed ring. In order to facilitate handling the press tool especially with large pipe diameters, there is at least one coupling member (49, 50) by means of which the adjacent clamping components (6, 10) can be temporarily connected, the coupling member (49, 50) being designed so as to be flexible in the coupled position in the closing direction.

Press tool for coaxially aligning and joining corresponding ends of workpieces, the press tool having a wraparound ring including hinged clamping components, in which the press tool is open at at least one closing point between two clamping components and has at least one member at that position for a closing device, by means of which the clamping components can be brought together to form a closed ring around at least one of the workpieces to be coaxially aligned and joined, characterized in that the press tool contains at least one coupling member (49, 50) by means of which the clamping components (6, 10) adjacent to the closing point(s) (46) can be temporarily connected, with the coupling member (49, 50) being designed so as to be flexible in the coupled position in the closing direction during the coaxial aligning of the ends of the workpieces;
- and
- wherein the coupling member contains a first coupling bracket (49) that is hinged to the clamping component (6), and a second coupling bracket (50) that is connected to the other clamping component (10), whereby the two coupling brackets (49, 59) may be hinged to one another.
Press tool for coaxially aligning and joining corresponding ends of workpieces, the press tool having a wraparound ring including hinged clamping components, in which the press tool is open at at least one closing point between two clamping components and has at least one member at that position for a closing device, by means of which the clamping components can be brought together to form a closed ring around at least one of the workpieces to be coaxially aligned and joined, characterized in that the press tool contains at least one coupling member (49, 50) by means of which the clamping components (6, 10) adjacent to the closing point(s) (46) can be temporarily connected, with the coupling member (49, 50) being designed so as to be flexible in the coupled position in the closing direction during the coaxial aligning of the ends of the workpieces;
- and
- wherein at least one clamping device (34, 35, 36, 37, 38), for the purpose of mounting the wraparound ring (5) on the inserted workpiece (1), is affixed on one side of the ring.
Press tool for coaxially aligning and joining corresponding ends of workpieces, the press tool having a wraparound ring including hinged clamping components, in which the press tool is open at at least one closing point between two clamping components and has at least one member at that position for a closing device, by means of which the clamping components can be brought together to form a closed ring around at least one of the workpieces to be coaxially aligned and joined, characterized in that the press tool contains at least one coupling member (49, 50) by means of which the clamping components (6, 10) adjacent to the closing point(s) (46) can be temporarily connected, with the coupling member (49, 50) being designed so as to be flexible in the coupled position in the closing direction during the coaxial aligning of the ends of the workpieces;
- and
- wherein the clamping components (6, 7, 8, 9, 10) are connected to one another via removable hinge pins (26, 27, 28, 29, 30, 31, 32, 33) outside of the closing point(s) (46).
A press tool for use in the encircling and aligning of pipe ends prior to joining in a manner such that the pipe ends have a common axis after being aligned, the press tool comprising:
- a wraparound ring having a plurality of hinged clamping components for encircling the circumference of at least one of the pipe ends, said wraparound ring being open at at least one closing point between a pair of said clamping components so that the pair of clamping components can be brought together so as to form a closed ring around and encircle said at least one pipe end;
- first and second pivotally mounted coupling members for connecting the pair of clamping components adjacent the closing point, said first coupling member including a first coupling bracket pivotally connected to one of the pair of clamping components, and said second coupling member including a second second coupling bracket pivotally connected to the other clamping component in said pair;
- and
- wherein said first and second coupling brackets include means for being pivotally connected to one another in order to effect said connecting of the pair of clamping components in closing said ring so as to align the pipe ends prior to joining.
A press tool for joining workpieces, having a wraparound ring including a plurality of hinged clamping components, in which the press tool is open at at least one closing point between two clamping components and has at least one member at that position for a closing device, by means of which the clamping components can be brought together to form a closed ring, characterized in that it contains at least one coupling member (49, 50) by means of which the clamping components (6, 10) adjacent to the closing point(s) (46) can be temporarily connected, with the coupling member (49, 50) being designed so as to be flexible in the coupled position in the closing direction;
- and
- wherein said coupling member contains a first coupling bracket (49) that is hinged to the claimping component (6), and a second coupling bracket (50) that is connected to the other clamping component (10), whereby the two coupling brackets (49, 50) may be hinged to one another.
