摘要： A power molding press is controlled, in which a stepped mold product having a plurality of stepped portions is molded by compressing powder within a mold by relatively moving an upper punch assembly, a lower punch assembly including a plurality of lower punches arranged concentrically with each other and the mold by detecting a speed ratio of moving speeds of the upper and lower punch assemblies moved by the respective driving sources at a time of compressing the respective stepped portions of the mold product during a compressing time from a pressing start time to a pressing completion time, detecting positions of the upper and lower punch assemblies and the mold, detecting a compression ratio of compressed dimensions of the stepped portions of the mold product, and controlling the respective drive sources to control the relative moving speeds of the upper punch assembly, the lower punch assembly and the mold so that the speed ratios substantially accord with the compression ratios of the respective stepped portion of the mold product.

摘要： A powder molding press includes a die plate provided with a die having a die hole, a punch device to be inserted into the die hole and a hydraulic cylinder device attached to the punch device for driving the same, the hydraulic cylinder device being arranged coaxially with the punch device. A movable punch plate may be disposed on one side of the die plate in parallel thereto with a predetermined space and a punch adapter for securing the punch device to the punch plate may be also disposed. The punch device includes a plurality of punches disposed axially in series. In this connection, a plurality of punch plates, hydraulic cylinder assemblies and punch adapters are arranged in a manner that succeeding cylindrical punches disposed axially in series are secured to corresponding punch plates through corresponding punch adapters each being inserted into a directly preceding punch adapter to be axially movable and that succeeding hydraulic cylinder assemblies for actuating corresponding punch plates are disposed axially in series each between a corresponding punch plate and a directly succeeding punch plate and arranged coaxially with corresponding punch adapters so that the succeeding punch adapter is axially movable along an inner peripheral surface of the through hole of a directly preceding hydraulic cylinder assembly.
