HYDRAULICALLY ACTUATABLE PRESSING DEVICE METHOD FOR PERFORMING PRESSING METHOD FOR PRODUCING AN ELECTRICALLY CONDUCTIVE PRESS-FIT CONNECTION ELECTRICALLY CONDUCTIVE PRESSED COMPRESSION SLEEVE METHOD FOR CLAMPING A WORKPIECE AND HYDRAULIC DEVICE

摘要

The present invention is, first of all, movable against the force of the recoil springs (21, 23) in the hydraulic cylinder, and having hydraulic pistons (20, 22) connected to the pressing parts (24, 27) for performing pressurization , Hydraulically operable, in particular in relation to a pressurizing device (1) formed of a handle-held device, in which case the hydraulic pistons (20, 22) are provided with a collision surface to generate a compressive force by the action of hydraulic means under hydraulic pressure. do. The hydraulic pistons 20, 22 are provided with first and second partial collision surfaces so that the pressurizing device can pressurize relatively large and small workpieces, such as a cable shoe, reliably even in a simple structure and without tool change. And second partial pistons 20, 22, wherein the first and second partial impact surfaces can be contacted by hydraulic means having the same hydraulic pressure, and the two partial pistons 20, 22 are made of It is connected to the 1st or 2nd pressurization part. The invention also relates to additional hydraulic pressurization devices and different methods.
