Abstract: The present invention relates to a transferring device for dies of presses and work pallets of machine tools and the like. A die transfer car is movable on two parallel rails, one side of the car is provided flanged wheels and the other side of which is provided plain wheels. When the car is stopped by a stopper having a stopper pin provided at the plain wheel side, through a stopping control device, the car is frictionally stopped by the flanges of the wheels and the side face of rails due to rotation caused by the inertia force around the stopper pin.

Abstract: The present invention relates to a work-clamp pallet used to clamp workpieces on a table of a machine tool to improve the working efficiency of the machine tool. This is achieved by shortening the time for exchanging workpieces on the table and for positioning workpieces on the table along both X and Y axes. A large number of workpieces are positioned on a work-clamp pallet along the Y-axis by the aid of a standard frame secured to a base block and along the X-axis by the aid of positioning stoppers projecting from the standard frame. The workpieces are clamped against the standard frame by clamping devices disposed at least on one side of the standard frame. The positioning and clamping a large number of workpieces on the base block is done outside the machine and, when the machine has stopped a machining over, a work-clamp pallet is transferred onto the table in exchange for that with finished workpieces which is removed.
