    摘要： A method of operating a mechanical press (1) having a servo motor (20) and its servo controller, and aims at decelerating the speed of a ram (36) immediately before a tool impinges against a workpiece in order to reduce noise at the time of impingement of the tool. Its servo controller program controls the servo motor (20) on the basis of the speed of the ram (36) and its locus of positions inputted for each step through each setting switch disposed on a panel. This invention enables optimizing the speed of the ram (36) through program control and can reduce the noise during the operation.

    摘要： A method of efficiently bending a lead of an electric part by use of a bender (1) including an upper die (10) and a lower die (30) without denting or scratching the lead and hence causing no peeling of the plating therefrom. The method comprises the steps of: clamping the root portion of the lead between a moving stripper (17) of the upper die (10) and a fixed die member (3) of the lower die (30); effecting a first motion in which the distal end portion of the lead that is clamped between a moving punch (18) of the upper die and a moving die member (31) of the lower die is pressed downwardly; and effecting a second motion simultaneously with the first motion, in which the moving punch and the moving die member, which clamp the distal end portion of the lead, are moved in a direction perpendicular to the direction of the first motion, thereby bending the lead along an approximately circular locus about the root portion of the lead by a resultant motion from the first and second motions of the moving punch and the moving die member.
