摘要:
A die (613) is supported in a die holder (18, 381, 581) such as a frame or an adapter supported in a frame such that it is operational use in a material deforming operation. One or both of the die (613) and the die holder (18, 381, 581) have at least one gas passage (683, 30, 31) which is substantially closed by at least part of the die. Gas such as pressurised air is directed into an end of the gas passage opposite the die via a hose connected to a gas source. If the die is broken or loose leak paths are available for the escape of gas past the die to or from atmosphere. A pressure sensor (40) connected to the hose detects the change in pressure of the gas and the magnitude of that pressure is used to determine the die condition. Alternatively a flow rate sensor (40) is used to detect a change in the flow rate of the gas in order to determine the condition of the die.

摘要:
A transfer device for a very high speed adiabatic face milling machine whose configuration and operation provide a highly efficient machining process suitable for production manufacturing conditions. The milling machine preferably operates at speeds of approximately 15,000 sfm and at efficiencies of approximately 7 cubic inches per minute per horsepower. The preferred milling operation is conducted without the use of cooling liquids, instead employing a chip removal system which enables the milling machine to operate truly adiabatically such that no heat is transferred to the workpiece or the cutter. The efficiency of the chip removal system is such that chip recutting is nearly eliminated and tool life is improved. The transfer device, by use of a transfer arm and associated grasping arms, locates the workpiece within a corresponding nesting slot defined by the grasping arms in order to accurately and securely move the workpiece between workpiece support structures so as to position opposing sides of the workpiece in the fixture for subsequent machining.

Le dispositif selon l'invention est destiné à manipuler les outils d'une machine à brocher verticale lors de leur échange. Il comprend essentiellement un bâti (1) pourvu en partie supérieure d'un coulisseau (11) mobile verticalement portant un chariot (14) mobile horizontalement, une table tournante (5) avec des moyens (6,7) pour recevoir les broches manipulées par l'ensemble chariot coulisseau. En plus, il comprend un châssis basculeur (18) qui permet de décharger ou recharger le dispositif en faisant passer les broches d'une position horizontale à une position verticale et inversement.
摘要:
A die (13) is supported in a die holder such as a frame or an adapter (18, 518) supported in a frame such that it is operational use in a material deforming operation. A washer (50) is disposed between the die head (20) and the die adapter holder (18, 518). One or both of the die and the die holder have at least one gas passage which is substantially closed by at least part of the die. Gas such as pressurised air is directed into an end of the gas passage opposite the die via a hose connected to a gas source. If the die is broken or loose, leak paths are available for the escape of gas past the die to or from atmosphere and the change in pressure of the gas and the magnitude of that pressure, or the flow rate of the gas are sensed.
