Embodiment Construction

[0038] Referring to the accompanying drawings, a portable fluid power tool for performing operations such as pressing, cutting, extending or pulling is generally indicated by reference numeral 1 .

[0039] The tool 1 comprises a housing 2 of elongate shape with a central part shaped like a handle 3 and a coupling part 4 for connecting, preferably snap-on, a battery 5 to the rear end of the tool 1 . The housing 2 houses, preferably at the handle 3, an electric motor 6 that can be powered by a battery through a supply circuit equipped with a switch (details not shown) on which a manual actuation button 7 arranged adjacent to the handle 3 acts. switch on.

[0040] The conversion mechanism 8 is arranged in the housing 2 on the side of the electric motor 6 opposite to the battery 5 . This conversion mechanism 8 is connected to the drive shaft 9 of the electric motor 6 and is adapted to convert the rotational movement of the drive shaft 9 into an oscillating translational movement ...

Abstract

A fluid power pressing and / or cutting tool (1) comprising: an electric motor (6); a conversion mechanism (8) suitable for converting the rotational motion of the electric motor (6) into an oscillating translational motion; a two-speed hydraulic pump (11), The drive piston (12) is moved by effecting an increase in pressure of the pressurized fluid acting on the drive piston (12) in response to an oscillatory translational movement.

Description

technical field [0001] The object of the present invention is to provide a hydrodynamic tool, in particular for carrying out operations such as pressing, cutting, stretching or pulling. A hydraulic pump and a mechanism for converting a rotary motion into an oscillating translational motion for such a hydrodynamic tool also form the object of the invention. Background technique [0002] To perform certain connecting operations (such as pressing of connectors around cables, pressing of rivets) or cutting operations (such as cutting of cables during installation and maintenance of electrical systems), hydrodynamic pressing and / or driven by motors are often used or cutting tools. [0003] Such tools typically include an electric motor powered by a battery and equipped with a drive shaft connected to a conversion mechanism that converts the rotational motion of the drive shaft into an oscillatory translational motion that is transmitted by a fluid power unit connected to the con...
