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 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 and 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 moveable between a first position and a second position, wherein in the first position the travelling part is in direct contact with the impinging part which causes the travelling part to act in a force-transmitting manner on the impinging part by the motor, wherein in the second position the travelling part is not in direct contact with the impinging part.

2. The pressing tool of claim 1 , wherein in a plan view of the pressing tool, an axially fixed threaded spindle extends until it overlaps with the impingement region perpendicular to a longitudinal axis of the threaded spindle.

3. The pressing tool of claim 1 , wherein the impinging part is connected to a lever part which is movable relative to the pressing jaw, wherein the impinging part can be acted upon for movement by the lever part, wherein the lever part through the application of manual force causes at least in part a pressing operation in the impingement region.

4. The pressing tool of claim 3 , wherein the lever part is mounted on the support part in a mounting area.

5. The pressing tool of claim 4 , wherein the lever part can be moved out of a first mounting location by a threshold value of the manual force acting on the lever part being exceeded.

6. The pressing tool of claim 5 , wherein a movement of the lever part in the mounting area is configured to trigger the switching on of the motor.

7. The pressing tool of claim 1 , wherein the impinging part acts on the pressing jaw via a control arm.

8. The pressing tool of claim 1 , wherein the impinging part acts on the pressing jaw via one or more rollers.

9. The pressing tool of claim 1 , wherein the impinging part and the travelling part are coaxially movable.

10. The pressing tool of claim 1 , wherein the impinging part is connected to a reset spring that acts in opposition to the direction of the pressing operation and is configured to move the impinging part.

11. The pressing tool of claim 10 , wherein the reset spring assigned at an advanced stage of the pivoting from a rest position into a pressing position of a pressing jaw has a steeper spring characteristic than that assigned to the start of the pivoting, wherein, the reset spring is constructed of multiple parts.

12. The pressing tool of claim 1 , wherein before a complete execution of a pressing operation, a switch activated release of the impinging part can be carried out for a return movement in order to enable the pressing jaw to pivot into an opening position.

13. The pressing tool of claim 12 , wherein the release of the impinging part can be carried out by a movement of the lever part under the exertion of manual force differently than a movement of the lever part in a pressing operation.

14. The pressing tool of claim 4 , wherein that the lever part acts upon a pivotable switch part by a control arm.

15. The pressing tool of claim 4 , wherein the lever part is rotationally mounted on the spindle.

16. The pressing tool of claim 1 , wherein two or more switches are provided.

17. The pressing tool of claim 16 , wherein all switches are provided on a common circuit board.

18. The pressing tool of claim 1 , wherein a light radiating in a direction of motion of the impinging part is provided.

19. The pressing tool of claim 2 , wherein a lubricant supply assigned to the spindle is provided.

20. The pressing tool of claim 2 , wherein the lever part acts upon the impinging part via an intermediate lever, said lever part moves the intermediate lever by a toothing system.

21. The pressing tool of claim 2 , wherein as a result of storing a value relating to the spindle position corresponding for example to the start of a pressing, a partial withdrawal of the impinging part and/or the travelling part is preset.

22. A pressing tool comprising:
a fixed support part;
a pressing jaw pivotably mounted about a pivot axis on the support part, 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 and extending in a longitudinal direction of the pressing jaw;
a motor;
a spindle drivable by the 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;
a travelling part movable on the spindle from a position distant to the impinging part to a position which acts in a force-transmitting manner on the impinging part by the motor; and
a lever part mounted on the support part in a mounting area, the impinging part is connected to the lever part, wherein the lever part through the application of manual force causes at least in part a pressing operation in the impingement region, the lever part can be moved out of a first mounting location by a threshold value of the manual force acting on the lever part being exceeded, and
wherein a movement of the lever part in the mounting area is configured to trigger the switching on of the motor.
