Definitions
- the present invention relates to a tool changing device for a numerically controlled machine for bending, forming, bending or bending bars or profiles.
- the main object of the invention is to provide a quick and automated tool change device, which does not exist in the current state of the art for this type of machine.
- the device according to the invention can in particular but not limitatively be applied to machines with digital control with erasable nose described in the patent application FR 00 04317 of the applicant.
- the invention consists of a numerically controlled machine for bending, forming, bending or bending a bar, machine conventionally comprising a frame, a bending tool rotating in order to be able to obtain folds in different planes, machine in which a bar is moved along a running axis and brought through a folding nose carried by the frame then through the folding tool whose axial digital movement, perpendicular to the running axis is transmitted from a motor by means a turner, characterized in that: on the one hand, the bending tool is carried by a standard conical tool support, on the other hand, that the turner is combined with automatic means for loosening the jaws pliers when the spinner
- FIGS. 1 and 2 block diagrams of a mode of production showing the gripper of the tool support respectively in the clamped position and in the loosened position.
- the applicant has chosen to use an assembly already used on other machine tools and for machining applications, namely a standard assembly [conical tool holder (1) and gripper ( 2)].
- the tool holder (1) with its tool (3) can be secured (or disengaged) by pliers (2) to a transmission assembly, called a spinner (4), of the movements of the motor electric (5) of the numerically controlled machine.
- the spinner allows in known manner to move the tool holder (1) in translation to distance or position the tool relative to the folding station.
- the invention consisted in automatically loosening the jaws (6) of the clamp (2) at the end of the translational movement of the spinner (4), for example according to the embodiment of FIGS. 1 and 2.
- a screw-nut system (8) for axial positioning of the spinner (4) drives the spinner axially in the direction of the motor (5) according to arrow F- ,.
- the axis (9) of the screw nut system comes into contact with the end of an axial guide rod (13) of the clamp (2) internally at the spinner, and drives said clamp (2) in an axial movement, relative to the spinner, according to arrow F 2 , in the opposite direction from Fj.
- the clamp approaches the conical stop and the jaws (6), under the effect of a spring located in the clamp and not referenced, move away in the flared part of the conical stop (7) thus automatically releasing the end of the tool holder (1).
- a device commonly used in machine tool machining, and not shown, ensures the exchange of assemblies [tool holder (1)-tool (3)] from an automated store.
- the tightening and loosening means can for example be driven by jacks, hydraulic or pneumatic, possibly external to the spinner.
