Abstract

A motorized manually operated pressing tool, in particular a crimping tool, with a fixed holding part, in which at least one pressing jaw is pivotably mounted about a pivot axis. The pressing jaw forms a working area and an impingement region extending in the longitudinal direction of the pressing jaw. In order to carry out a pressing operation the impingement region can be acted upon with an impinging part that is movable relative to the impingement region. The impinging part is movable in the longitudinal direction of the impingement region by exertion of manual force and by a motor.

First claim

The invention claimed is:

1. A pressing tool comprising:
a fixed support part;
a pressing jaw pivotably mounted on the fixed support part about a pivot axis, the pressing jaw forming a working area on a first side of the pivot axis and an impingement region on a second, opposite side of the pivot axis, the impingement region extending in a longitudinal direction of the pressing jaw;
a motor;
an impinging part that is movable relative to the impingement region in the longitudinal direction of the impingement region, wherein in order to carry out a pressing operation the impingement region can be acted upon with the impinging part by exertion of manual force and by force from the motor; and
a travelling part movable relative to the impinging part;
wherein the impinging part is movable between a first position and a second position, wherein in the first position the impinging part is at a first distance relative to the travelling part or is in contact with the travelling part, wherein in the second position the impinging part is at a second distance relative to the travelling part, the second distance being greater than the first distance, wherein the impinging part is moved by hand into the second position, and wherein the travelling part is further movable through the second distance by motor force so as to contact the impinging part and move the impinging part.

2. A pressing tool having a longitudinal direction, comprising:
a fixed support part;
a first pressing jaw pivotably mounted on the support part about a first pivot axis, the first pressing jaw forming a first working area on a first side of the first pivot axis and a first impingement region on a second, opposite side of the first pivot axis, the first impingement region extending in the longitudinal direction of the tool;
a second pressing jaw pivotably mounted on the support part about a second pivot axis, the second pressing jaw forming a second working area on a second side of the second pivot axis and a second impingement region on a second, opposite side of the second pivot axis, the second impingement region extending in the longitudinal direction of the tool;
an electric motor;
a transmission;
an axially fixed threaded spindle having a longitudinal axis extending in the longitudinal direction of the tool, the spindle extending between the first and second impingement regions of the first and second pressing jaws, the spindle overlapping the first and second impingement regions perpendicular to the longitudinal axis thereof, wherein the electric motor, the spindle and the transmission are arranged one behind the other in the longitudinal direction of the tool; and
an impinging part longitudinally movable relative to the first and second impingement regions, wherein in order to carry out a pressing operation the first and second impingement regions can be acted upon with the impinging part by exertion of manual force on the impinging part and by force from the motor on the impinging part, the impinging part being pulled for completion of a pressing by the electric motor in a direction toward the electric motor.
