摘要： A COMBINED MACHINE IS DISCLOSED FOR FORMING THREADED ARTICLES FROM ROD OR WIRE STOCK. THE MACHINE INCLUDES A PROGRESSIVE HEADER OPERABLE TO UPSET BLANKS AND A RECIPROCATING THREAD ROLLER OPERABLE TO THREAD THE BLANKS. THE HEADER INCLUDES A CRANK AND PITMAN DRIVEN RECIPROCATING SLIDE AND THE THREADER INCLUDES A CRANK AND PITMAN DRIVEN THREAD ROLLING SLIDE. A RECIPROCATING BALANCING MASS IS PROVIDED ON THE MACHINE ON THE SIDE OPPOSITE FROM THE THREAD ROLLING SLIDE. THE DRIVES FOR THE FORMING SLIDE, THREAD ROLLING SLIDE, AND RECIPROCATING MASS ARE ARRANGED SO THAT THE THREAD ROLLING SLIDE AND RECIPROCATING MASS COOPERATE TO PROVIDE SUBSTANTIALLY COMPLETE DYNAMIC BALANCE OF THE ACCELERATION FORCES OF THE FORMING SLIDE. THE CRANK SHAFT IS PROVIDED WITH ROTATING ECCENTRIC MASSES ARRANGED SO THAT THE ROTATING MASSES ARE ALSO DYNAMICALLY BALANCED TO A SUBSTANTIAL EXTENT. BECAUSE SUBSTANTIALLY COMPLETE DYNAMIC BALANCING IS PROVIDED, THE MACHINE MAY OPERATE AT HIGHER SPEEDS WITHOUT DAMAGING VIBRATION.

摘要： A FORGED BLANK FOR FORMING HELICAL GEARS IS DISCLOSED THE BLANK IS PROVIDED WITH SHALLOW HELICAL TIMING GROOVES FORMED BY PRESSING THE BANK THROUGH AN EXTRUSION DIE HAVING INWARDLY PROJECTING HELICAL TEETH. THE MATERIAL DISPLACED TO FORM THE GROOVE FLOWS INWARDLY TOWARD AN AXIAL PASSAGE THROUGH THE BLANK. THE APPARATUS FOR FORMING THE BLANK INCLUDES A NON-ROTATING PUNCH FORMED WITH A PLANAR END FACE AND A DIE ASSEMBLY INCLUDING A PORTION FORMED WITH INWARDLY EXTENDING HELICAL TEETH. THE BLANK ROTATES AROUND ITS AXIS AND RELATIVE TO THE PUNCH AS IT MOVES THROUGH THE EXTRUSION DIE. THE PUNCH DOES NOT ENTER THE TOOTHED PORTION OF THE DIE AND A SUBSEQUENT BLANK UTILIZED TO PRESS THE PRECEDING BLANK THROUGH THE DIE. THE BLANK IS RADIALLY CONFINED BEFORE EXTRUSION LOADS ARE APPLIED THERETO AND THE END FACE OF THE BLANK IS FULLY SUPPORTED BY THE PUNCH OR A SUBSEQUENT BLANK.

摘要： A disc brake for heavy machinery such as metal working presses and the like which includes a rotatable disc mounted on a projecting shaft for rotation with the shaft and for axial movement relative to the shaft. A stationary brake ring is mounted on the frame of the machine and has a face adjacent to one side of the disc. The other side of the disc faces an axially movable brake ring which is locked to the stationary brake ring to prevent relative rotation therebetween. A cover plate is fixed to the stationary brake ring. Springs are provided between the cover plate and the axially movable brake ring to bias the brake against the disc to thereby apply braking pressure to the shaft and fluid motor means are provided to overcome the bias of the springs to thereby release the brake. Shims are provided between the cover plate and the stationary brake ring so that, as the braking surfaces wear, the initial spring tension may be reestablished by removing one or more shims.

摘要： A transfer system is disclosed for progressively transferring work pieces between die stations of a progressive forging machine. The transfer includes a pivoted frame on which a reciprocating slide is supported. Work pieces gripping fingers are carried by the slide for movement from a gripping position to a release position. Pivotal movement of the frame moves the fingers out away from the die face to provide clearance for turning of the fingers. Finger turning is in response to reciprocation of the finger supporting slide. A first cam driven linkage controls the oscillating pivotal movement of the frame and a second cam driven linkage controls the gripping and release of the fingers. The two linkages are arranged to be substantially unaffected by the pivotal movement of the frame and the reciprocating movement of the slide. The transfer is arranged to permit easy removal of one slide with work piece gripping fingers thereon and the substitution of a different slide with a different type of work piece gripping fingers. Therefore, the transfer system can be easily modified to accommodate different types of work pieces and to permit different types of forming operations within a single machine.
