Abstract

The invention relates to a bending tool ( 3 ) for inserting into a tool mount ( 2 ). The bending tool comprises a tool body ( 4 ), a locking element ( 8 ) which is connected to an activating element ( 7 ) accessible outside of the tool mount ( 2 ) and which has a locking tab ( 9 ) for securing the bending tool ( 3 ) in the tool mount ( 2 ) by engaging in a recess arranged therein, wherein a base position of the activating element ( 12 ) corresponds to a unlocking position of the locking element ( 16 ) and an actuating position of the activating element ( 13 ) corresponds to a locking position of the locking element ( 15 ). Furthermore, there is a tool position securing element ( 17 ) attached displaceably in the tool body ( 4 ), which tool position securing element, in a securing position ( 18 ) that protrudes with respect to the tool body ( 4 ), establishes a connection for fixing the position of the tool body ( 4 ) with respect to a displacement direction ( 5 ) in the tool mount ( 2 ). Both the locking element ( 8 ) and the tool position securing element ( 17 ) are connected to the same activating element ( 7 ).

First claim

The invention claimed is:

1. An assembly comprising a tool mount and a bending tool insertable into the tool mount;
wherein the tool mount comprises a recess;
wherein the bending tool comprises
a tool body;
a tool position securing element attached displaceably in the tool body;
an activating element accessible outside the tool mount; and
a locking element coupled to the activating element and comprising a locking tab for securing the bending tool in the tool mount by engaging in the recess;

wherein the activating element has a basic position corresponding with an unlocking position of the locking element and an activating position corresponding with a locking position of the locking element;
wherein the tool position securing element has a securing position wherein the tool position securing element protrudes relative to the tool body and forms a connection for fixing the tool body in the tool mount in a position relative to a displacement direction; and
wherein both the locking element and the tool position securing element are coupled to the activating element.

2. The assembly as claimed in claim 1 , wherein the tool position securing element is coupled to the activating element via the locking element.

3. The assembly as claimed in claim 1 , wherein both the tool position securing element and the locking element are coupled directly to the activating element.

4. The assembly as claimed in claim 1 , wherein the locking element and the tool position securing element are movably coupled to one another by a mechanical connection.

5. The assembly as claimed in claim 1 , wherein the locking element and the tool position securing element are movably coupled by an essentially incompressible fluid.

6. The assembly as claimed in claim 1 , wherein the tool position securing element has a frictional surface for forming a non-positive connection with the tool mount.

7. The assembly as claimed in claim 1 , further comprising a spring element pretensioning the tool position securing element toward the securing position.

8. The assembly as claimed in claim 7 , wherein the spring element is a leaf spring oriented in an adjusting direction of the tool position securing element and bendable by a force applied transversely to a longitudinal extension of the leaf spring to shorten a distance the leaf spring extends longitudinally.

9. The assembly as claimed in claim 7 , wherein the spring element is formed by a helical spring.

10. The assembly as claimed in claim 7 , wherein the tool position securing element has first and second ends and a surface between the first and second ends, wherein the surface is angled relative to a direction of movement of the tool position securing element and contacted by an activating tab of the locking element or the activating element.

11. The assembly as claimed in claim 1 , wherein the tool position securing element is designed to be circular cylindrical and is guided in a bore in the tool body.
