摘要： A method for hydraulic control of a toggle lever press in which the velocity of a driving piston rod is increased at least once in the working region of a press ram. The velocity of the press ram is thus kept relatively constant up to bottom dead center (or upper dead center) of the press ram. A toggle lever press has a control adapted for carrying out this method.

摘要： In a method of operating a press machine having a servomotor (20) and a servo controller therefor, the tool stay substantially still immediately after the completion of working a workpiece for a period of from 0.05 to 2 seconds and also the speed of the tool applying an impact to the workpiece for working is decelerated immediately before the tool strikes against the workpiece in order to reduce the noise generated when the impact is applied. The speed and positional locus of the ram (36) are set for each step using respective setting switches provided on a panel. The servomotor (20) is program-controlled according to the data input through the respective setting switches.

摘要： A spacing adjustment and overload releasing mechanism in a stamping press having a base and a crown spaced from one another and a ram operating therebetween, in which posts interconnect the base and crown and the spacing between the ram and base is adjustable by a nut and collar disposed on opposite sides of the crown, and a fluid operated means such as a hydraulic cylinder for each of the posts disposed in the base applies pressure urging the crown and base toward one another at substantially equal pressures, greater than the normal pressure applied by the ram, but at a pressure sufficiently low that it is within the load capacity of the press frame. The nut and collar provide the initial adjustment between tool sections operated by the ram and base while the fluid operated means provides an overload release in the event excessive pressure is applied by the ram.

摘要： A drive for operating a punching tool comprises a toggle-joint lever to one of whose lever members the punching tool is operatively connected. The second lever member of the toggle-joint forms part of a quadrilateral linkage. This linkage consists of the second lever member, a first transverse lever member linked at one end to the second lever member and at the other end to another lever element, and a second transverse lever member linked at one end to the other lever element. The first transverse lever member is a two-armed lever supported on a fixed pivot near its linkage to the second lever member for pivoting the two-armed lever about the fixed pivot. The second transverse lever member and the other lever element are linked to a crank drive.

摘要： A press having both upper and lower punch operations with controlled action stroke for both upper and lower punches slidable in opposed directions with relationship to a multiple cavity die plate. The upper ram and punches are operated in the downward stroke by a toggle and rocker arm mechanism which incorporates a readily adjustable eccentric means for controlling the length of upper ram stroke. The mechanism further includes a combination of first and second class levers which are cam driven in a cyclical press operation.
