摘要： Control systems for indenters used in cold working processes, and in particular, for StressWave cold working of metal workpieces. Load on an indenter is increased by increasing the force applied, such as by pressure in a hydraulic reservoir acting on a piston. When the load reaches a desired limit, as may be calibrated by the pressure in the fluid reservoir responsive to the piston being driven by the indenter, then a pressure relief valve allows the fluid to flow from the cylinder to a hydraulic reservoir, thus allowing the indenter shaft to move away from the workpiece. Then, on recycle of the apparatus, an automatic control system reacts to such movement and pumps fluid back to the reservoir, and thus returns the indenter shaft to a pre-determined position. In one embodiment, the pressure relief valve is integrated into, or attached to, the indenter. Other embodiments are disclosed for control of various compound or simple indenters.

摘要： The quick tool clamping system relates to a cornice brake in which there are rows of punches and dies and modular units consisting of intermediates and clamping jaws for the intermediates and jaws for clamping punches, with the latter being operated by actuators driven by pneumatic cylinders, and is characterized in that: a) in the intermediates and the jaws clamping the intermediates to the cursor of the press there are channels for feeding of the fluid under pressure to the actuator cylinder; b) said channels lead to at least one hole opening onto the opposing surfaces of each pair of intermediates and associated clamping jaw; and c) on at least one of the two opposing surfaces of each pair of intermediates and associated clamping jaw the associated hole opens onto a groove running horizontally in the surface and positioned at the same level as the hole opening onto the opposing surface, and in the circuit for supplying the fluid under pressure to every intermediate a valve is inserted designed to intercept the flow of fluid towards the intermediate. In accordance with a variation the groove running horizontally is missing and the holes opening onto the opposing surfaces of each pair of intermediates and associated clamping jaw are mutually opposed.

The holder has a body with walls defining a downwardly open, tool receiving recess having a top, a downwardly facing force-delivering shoulder adjacent the bottom of said recess, and a shelf within said recess having an upwardly facing surface spaced upwardly from said force-delivering shoulder. The tool comprises a body having a lower work-engaging surface, an upwardly facing force-receiving shoulder engageable with the shoulder of the tool holder, and an upwardly extending tang receivable in said recess, the upper end of the tang being spaced from the top of the recess. A manually operable actuator is spaced below said force-receiving shoulder, and a safety key is coupled to the actuator for movement horizontally into and out of alignment with the shelf between locked and unlocked positions, respectively.

摘要： Press brake tool holders suitable for releasing and securing press brake tools in response to applied fluid pressure. One press brake tool holder includes a horizontally elongated body having a cam shaft bore disposed longitudinally therethrough, and receiving a slidably and sealingly mounted cam shaft therein. The cam shaft can have at least one axial camming surface, having a large outer diameter region axially tapered to a small outer diameter region, and in contact with a cam follower pin slidably disposed in a cam follower pin bore transversely disposed through the body. The cam follower pin can bear against a pivotally mounted clamp disposed about the body. In response to applied fluid pressure, the camming surface can slide axially, thereby increasing the effective outer diameter as seen by the cam follower pin, thereby urging the cam follower pin outward and against the upper portion of the pivotally mounted clamp, and closing the lower clamp portion about a press brake tool. One press brake tool has a pair of opposed cam shaft segments with the pressure-bearing faces disposed near each other in the center. Another press brake tool holder has a single cam shaft with multiple camming surfaces disposed over the length.
