METODO E DISPOSITIVO PER METTERE SOTTO PRESSIONE UNA PRESSA PER LA PREPARAZIONE DI ATTREZZI

摘要

A method and device are provided to prepare a cutting tool such as used for die cutting sheet material, by mounting the cutting members in a mounting support with the method and device controlling the operational stages of the preparation. The device includes improvements in the press which are that a plurality of individual pressure elements are arranged on a support surface of a lower bed in rows and columns to form a rectangular configuration with each of the elements being individually controlled so that different groups of elements can be actuated to act on a pressing plate depending on the size of the cutting tool being prepared. To insure an accurate and equal pressure, the elements in each corner are actuated with a low pressure to bring the pressing plate and the tool being acted on into contact with the pressure surface of the upper bed and then high pressure is applied to the selected pressure element to insure the securing of the cuttings blades and members into a support of the cutting tool.
