Abstract

A mounting device ( 12 ) for mounting a tooling board ( 14 ) in a flat bed die-cutting, stripping or blanking machine comprises at least one first clamping jaw ( 38 ) which is moveable from an unlocked position, in which a tooling board ( 14 ) may be removed from or inserted into the machine, to a locked position, in which a tooling board ( 14 ) may be fixed in the machine, at least one actuator ( 18 ) which comprises a moveable piston ( 54 ) and a piston rod ( 56 ) coupled to the piston ( 54 ), wherein the actuator ( 18 ) is configured to transfer the at least one first clamping jaw ( 38 ) from the locked position to the unlocked position, and wherein the actuator ( 18 ) is coupled to the at least one clamping jaw ( 38 ) via an attachment point ( 60 ) which has a fixed position relative to the first clamping jaw ( 38 ). Furthermore, a mounting assembly ( 10 ) comprising a mounting device ( 12 ) is provided.

First claim

The invention claimed is:

1. A mounting device for mounting a tooling board in a machine, the mounting device comprising:
a first clamping jaw which is moveable from an unlocked position, in which the tooling board may be removed from or inserted into the machine, to a locked position, in which the tooling board may be fixed in the machine; and
an actuator which comprises a moveable piston and a piston rod coupled to the piston,
wherein the actuator is configured to transfer the first clamping jaw from the locked position to the unlocked position, and
wherein the actuator is coupled to the first clamping jaw via an attachment point which has a fixed position relative to the first clamping jaw,
wherein the actuator is coupled to the first clamping jaw via a swivel joint,
wherein the mounting device comprises a closing spring which is arranged to move the first clamping jaw towards the locked position, and
wherein the closing spring is clamped between a first abutment surface of the piston rod and a second abutment surface which has a fixed position in the mounting device.

2. The mounting device according to claim 1 , wherein the closing spring is arranged coaxial with the piston rod.

3. The mounting device according to claim 1 , wherein the mounting device has a linear guide for support and movement of the first clamping jaw.

4. The mounting device according to claim 1 , wherein the first clamping jaw comprises a guiding portion made of sheet metal, wherein the actuator is coupled to the guiding portion.

5. The mounting device according to claim 4 , wherein the guiding portion has a slit which extends in a moving direction of the first clamping jaw, and wherein the mounting device has a protrusion which extends through the slit and thereby guides the first clamping jaw.

6. The mounting device according to claim 1 , wherein the mounting device comprises a clamping profile which is fastened to the first clamping jaw and which is configured to engage the tooling board.

7. The mounting device according to claim 1 , wherein the mounting device comprises a second clamping jaw which constitutes a counter bearing to the first clamping jaw, wherein the first and the second clamping jaws are configured to clamp a tooling board between each other.

8. The mounting device according to claim 7 , wherein the actuator is fixed to the second clamping jaw.

9. The mounting device according to claim 7 , further comprising a bridge having a first end portion and a second end portion opposite to the first end portion, wherein the first clamping jaw is displaceably mounted to the first end portion of the bridge and the second clamping jaw is displaceably mounted to the second end portion of the bridge.

10. A mounting device for mounting a tooling board in a machine, the mounting device comprising:
a first clamping jaw which is moveable from an unlocked position, in which the tooling board may be removed from or inserted into the machine, to a locked position, in which the tooling board may be fixed in the machine;
an actuator which comprises a moveable piston and a piston rod coupled to the piston;
a second clamping jaw which constitutes a counter bearing to the first clamping jaw; and
an adjustment device which is configured to adjust a position of the tooling board in the machine,
wherein the actuator is configured to transfer the first clamping jaw from the locked position to the unlocked position,
wherein the actuator is coupled to the first clamping jaw via an attachment point which has a fixed position relative to the first clamping jaw,
wherein the first and the second clamping jaws are configured to clamp a tooling board between each other,
wherein the actuator is fixed to the second clamping jaw.

11. The mounting device according to claim 10 , wherein the second clamping jaw is displaceable by the adjustment device along a direction of movement of the first clamping jaw.

12. A mounting assembly comprising:
a mounting device for mounting a tooling board in a machine, the mounting device including:
a first clamping jaw which is moveable from an unlocked position, in which the tooling board may be removed from or inserted into the machine, to a locked position, in which the tooling board may be fixed in the machine;
an actuator which comprises a moveable piston and a piston rod coupled to the piston; and
a frame,

wherein the frame and/or the tooling board are removably mounted in the mounting device by the first clamping jaw,
wherein the tooling board is attachable to the frame,
wherein the actuator is configured to transfer the first clamping jaw from the locked position to the unlocked position,
wherein the actuator is coupled to the first clamping jaw via an attachment point which has a fixed position relative to the first clamping jaw, and
wherein the actuator is coupled to the first clamping jaw via a swivel joint.
