Forging machine
Abstract
Abstract A FIVE STATION PROGRESSIVE COLD FORMER IS DISCLOSED WHICH IS ARRANGED TO PERMIT RELATIVELY QUICK TOOL CHANGEOVER. THE DIE BREAST, THE BOLSTER PLATE AND THE SHEAR ELEMENTS ARE REMOVABLY CLAMPED IN THE MACHINE BY HYDRAULICALLY-OPERATED CLAMP ACTUATORS. A KNOCKOUT MECHANISM IS PROVIDED WITH A CAM DRIVE WHICH INCLUDES CAM SECTORS THAT CAN BE REMOVED AND REPLACED WITHOUT MATERIAL DISASSEMBLY OF THE CAM DRIVE. AN ADJUSTABLE TUBE NUT IS THREADED INTO THE MACHINE TO ADJUSTABLY DETERMINE THE REARWARD POSITION OF THE KNOCKOUT MECHANISM. POWER MEANS ARE PROVIDED FOR THE ADJUSTMENT OF THE TUBE NUTS. THE SEPARATE FIXTURES ARE PROVIDED TO PERMIT INSTALLATION OF TOOLING AND ROUGH ADJUSTMENT THEREOF ON A DIE BREAST AND BOLSTER ASSEMBLY SEPARATE FROM THE MACHINE. THE MACHINE IS ARRANGED SO THAT A TOOLING CHANGE CAN BE ACCOMPLISHED BEFORE THE MACHINE COOLS TO ENVIRONMENTAL TEMPERATURE SO THAT WARM-UP ADJUSTMENT REQUIREMENTS ARE MINIMIZED.
