Definitions
- the invention relates to a machine for machining workpieces, with a machining tool and with a lifting drive, by means of which a workpiece can be acted upon by the machining tool and having a spindle drive with at least one drive unit and with a Kraftein effets- element, wherein the drive unit spindle drive elements in For ⁇ n a drive spindle and a spindle nut mounted thereon, which are supported by a threaded engagement with each other, one of which as close to the workpiece Spindle drive element and the other is provided as remote workpiece spindle drive element and are under application of the workpiece by the drive tool by a drive motor about a spindle drive shaft rotatable relative to each other, wherein the workpiece near the spindle drive element acted upon by a force acting on the workpiece by the processing tool force and the force is supported on the associated workpiece remote spindle drive element via the threaded engagement under the action of this force.
- Such a machine is disclosed in JP 04172133 A.
- the prior art relates to a punching machine with a motorized lifting drive for a punching tool.
- the linear actuator comprises a spindle drive with a single drive spindle and a seated thereon and motor-driven spindle nut.
- a rotary drive is provided on the previously known punching machine, by means of which the punching tool can be adjusted in rotation about the lifting axis of the lifting drive.
- a lifting drive is provided with a spindle drive comprising two coaxial drive units with mutually associated spindle drive elements.
- the introduction of machining forces or reaction forces resulting therefrom into the spindle drive takes place in the direction of the common spindle drive axis between the threaded engagements of the workpiece-near and workpiece-remote spindle drive elements of the two drive units.
- the forces to be absorbed by the spindle drive during workpiece machining are evenly distributed both drive units. This is particularly advantageous for workpiece machining with high machining forces.
- the common force introduction element for distributing forces acting in the direction of the spindle drive axis and / or in the transverse direction of the spindle drive axis forces on the drive units of the machine according to the invention.
- the common force introduction element of the two drive units of the spindle drive in the interest of a constructive simplification of the linear actuator unitary, in particular integrally formed with a power transmission element, which in turn initiated by the common force application element in the drive units force in the joint force Conduit transmits.
- the Erfindungsbauart according to claim 5 is characterized by a particularly compact design.
- inventive concept of "central" force introduction for inventive machines of the type described in claim 6.
- the mutual bias of the spindle drive elements provided on such machines drive units is on the one hand for the functioning of the respective drive units of great importance.
- the resulting from the mutual bias of the spindle drive elements backlash of the threaded engagement between the spindle drive elements allows a very precise stroke control of the drive units and a direction of rotation of the relatively rotated spindle drive elements without associated vibrations.
- such drive units are particularly sensitive to the introduction of oversized loads, since there is no possibility of receiving deformations occurring at the spindle drive elements by a play between these components.
- each of the drive units is as a rule assigned its own drive motor.
- the operation of the drive units but also with a single, correspondingly powerful drive motor is possible. .
- Claim 8 relates to a particularly significant for operational practice opportunity to implement the inventive concept. For example, punching machines of the type required in the art often have to apply high machining forces or to remove corresponding reaction forces.
- an effective in the direction of the spindle drive axis axial biasing device is provided on punching machines according to the invention for the workpiece-near spindle drive elements.
- Such pretensioning devices increase the service life and the functional safety of the lifting drive of punching machines according to the invention.
- the biasing device counteracts a sudden load change on the lifting drive. With appropriate selection of the bias results in a less wear causing swelling stress of the spindle drive instead of changing stress.
