A coupling device for joining pipe ends has at least one pressing sleeve which can be slipped on a pipe end and pressed together with the pipe end. The pressing sleeve is elastically designed in the area of its inner surface pressed on the pipe end so that an expansion of the pipe end caused by temperature variations can be absorbed by elastic shear deformation of the elastic area, without causing the pipe end to slide in the pressing sleeve.

A pressing device comprises a press ring having at least three pivotally interconnected compression jaws. The press ring has a first open configuration, and a second closed configuration. A coupling element extends from each of two jaws for operable connection to a closing device. The closing device shifts the press ring between the configurations, and includes two oppositely disposed pivotal levers. A drive device is operably engageable with each of the levers, for pivoting the levers and thereby causing the ring to be shifted between the configurations.

Compression tool for compression molding die

A pressing tool for transforming workpieces includes a first fixed position die for transforming the workpiece. A second die cooperates with the first die in transformation of the workpiece, and the second die is coupled to and movable in response to operation of a forward feed device. The forward feed device comprises a rough feed device for relatively rapidly moving the second die toward the workpiece, and a fine feed gear for relatively slowly moving the second die toward the workpiece. The fine feed gear is coupled to and movable with the rough feed device. The forward feed device causes control over movement of the forward feed device to be shined from the rough feed device to the fine feed gear upon engagement of the second die with the workpiece.

Tool for transforming work pieces

Press tool

A pressing instrument for pressing bushings, cable lugs, or similar items upon a work piece reveals two tools that can be brought together with the help of a drive mechanism, forming a pressing chamber, with each tool revealing two opposite pressing cheeks, whose pressing surfaces are shaped so that a polygonal shape will result during pressing. In order that work pieces of differing diameter can be processed with the pressing tool, that production costs can be kept comparatively low, and that good operational reliability can be achieved, opposite pressing cheeks (10, 11; 36, 37, 54, 55) of at least one tool (4, 34, 35) can be swung on them so that the other tool (5, 34, 35), as the tools are brought together (4, 5, 34, 35), will run against the swingable pressing cheeks (10, 11, 36, 37, 54, 55) and will swing them out of a starting position into a pressing position forming the pressing chamber.

A compression tool includes a housing having adjacently disposed first and second oppositely disposed portions defining therebetween a clearance. First and second pivot levers are provided, and each of the levers is pivotally secured to one of the portions and extends therefrom beyond the housing. At least three compression jaws are operably associated with the housing and disposed about the clearance. One of the jaws is secured to the housing and the other two of the jaws are each connected to one of the levers and are pivotal therewith. The one jaw is separate from the first and second levers. Each of the jaws has an arcuate compression surface. A movement assembly is operably associated with each of the levers and the associated jaw for causing cooperating movement thereof. A drive assembly is operably associated with each of the levers and is disposed exteriorly of the housing for causing pivoting thereof between a first open position and a second closed position. Pivoting of the levers from the first open to the second closed position causes the other two jaws to pivot on each respective lever and relative to the one jaw so that the compression surfaces define a circle for compressing a work piece therebetween.

Compression tool

A compression tool for joining tubular workpieces is provided with two or more arcuate compression jaws displaceable relative to each other in such a manner that the jaws can be opened for placement o a tubular segment of the workpiece. The compression tool (121) comprises compression jaw supports (132, 133) pivotally mounted on pivot bolts (134, 135). Two compression jaws (142-145) of each jaw support are guided along guide surfaces (138-141) which subtend an angle symmetrical to the center of the compression space when the compression jaws are in a closed state. The compression jaws are biased by a spring (146-149) along the guide surfaces (138-141) toward terminal end stops (150-153). Movement of the jaw supports about the pivot bolts (126, 127) permits opening and closing of the compression jaws.

The present invention provides an adjustable and automatically disengaging overload clutch for driving a tool, comprising a first clutch half frictionally engaged with a second clutch half and a coupler bracket for transmitting torque from the second clutch half to the tool. The clutch further comprises a spring connecting the second clutch half to the coupler bracket to transmit torque from the second clutch half to the coupler bracket. The spring is designed so that if a predetermined torque is exceeded, the second clutch half is released from the coupler bracket, thus preventing the transmission of any further torque. Levers associated with the coupler bracket and the second clutch half are also provided for disengaging the second clutch half from the first clutch half.

Overload clutch with automatic disengagement

The present invention provides an adjustable and automatically disengaging overload clutch for driving a tool, comprising a first clutch half frictionally engaged with a second clutch half and a coupler bracket for transmitting torque form the second clutch half to the tool. The clutch further comprises a spring connecting the second clutch half to the coupler bracket to transmit torque from the second clutch half to the coupler bracket. The spring is designed so that if a predetermined torque is exceeded, the second clutch half is released from the coupler bracket, thus preventing the transmission of any further torque. Levers associated with the coupler bracket and the second clutch half are also provided for disengaging the second clutch half from the first clutch half.

A flywheel continuously rotates, A piston within the rotating flywheel presses on a support which in turn presses on a friction clutch to engage the spindle press, whcih causes it to rotate with the flywheel. Upon disengagement, piston pressure is released, the spindle press lags and a part of the support lags with the spindle press, quickly disconnecting pressure on the friction clutch. Thus, the driving connection of the flywheel and spindle press is immediately disengaged from the flywheel without dealy otherwise caused by the slowness of return movement of the piston.

A bending machine comprises a support to which first and second spaced cooperating bending devices are displaceably mounted. Each of the bending devices have first and second spaced cooperating bending components and the components of the first and second bending devices define a first axis extending between the bending devices and further define second and third axes extending generally transverse to the first axis and about which a length to be bent may pivot and each of the second and third axes are disposed between the components of one of the bending devices. A drive mechanism is operably associated with at least one of the components of each of the bending devices for causing displacement thereof. A guide system is operably associated with the support and with each of the bending devices so that displacement of the bending components by the drive system causes the bending components to move relative to the first axis and to engage the length to be bent extending between the devices. The guide system further permits the bending devices to move along the guide system relative to each other so that the length is bent intermediate the bending devices.

A clutch and safety overload for portable, power driven, hand tools is described. The clutch comprises a fixed half and a movable half which are urged into contact with each other more firmly as the load requirements increase. The load torque is fed back to the movable clutch half by a gear driven by the output spindle and which meshes with helical gearing carried by a jackshaft on which the movable clutch half is mounted. In one embodiment the overload safety is part of the clutch itself and involves a rotation of the movable clutch half in response to an overload condition, and against a spring force, which causes it to be displaced axially with respect to the jackshaft and out of engagement with the fixed clutch half. In a second embodiment, the overload safety comprises a mechanical linkage which disengages the clutch halves when the output stroke of the driven tool exceeds a predetermined amount.
