Definitions
- the invention relates accordingly to a turret cutting press the preamble of claim 1.
- Turret cutting presses are known tool systems for cutting Processing of large-area or sheet-like workpieces. she are generally with a workpiece positioning device, for example a coordinate table, by means of which the machining workpiece positioned relative to a work station in which is loaded according to a CNC control Programs that actually process workpiece machining automatically.
- a workpiece positioning device for example a coordinate table
- Essential features of turret cutting presses are upper and lower order a common axis rotatably mounted motor and in discrete Lockable turret plates that can be locked in the peripheral area are equipped with a variety of tool sets, the In general, at least the upper tool loaded in the upper turret plate from a stamp and a scraper and that in the lower
- the turret plate loaded lower tool consists of at least one die.
- the upper and lower tools are always coordinated and they are individual complete tool sets consisting of one Upper and one lower tool by rotating the turret plate together transferable to the workstation. Because upper and lower tools Always used together is a synchronized drive the upper and lower turret plates required.
- a press ram works in the work station by means of a mechanical one or hydraulic drive on the upper tool, which according to the mentioned work program by previous rotation the turret plate has been transferred to the work station.
- An advantage of such machine systems is that according to the requirements of the tool reservoir loaded in the turret plates into the Machining workpiece openings of any shape and on any Positions can be introduced so that the operation of such machines extremely flexible and efficient in use.
- a practical technical limitation is that the Number of turrets in the turret for a machining in Readiness to keep tool sets is limited.
- the turret plates can be deficient with regard to the The space requirement of the machine cannot be increased arbitrarily. That stands also the related machine weight as well as that, with increasing Diameter of increasing mass moment of inertia of the turret plate counter, which is for an exchange of in the workstation located tool set the use of with increasing Diameter of the turret plate with regard to their installed capacity disproportionately increased drives required to those required for a tool change in the work station Change times within limits despite increasing the turret plate diameter to keep.
- a turret punch press is known from DE 22 64 851 B2, the Tool sets depending on their absolute dimensions on different to each other and to the common axis of the one above the other arranged turret plate arranged concentric circles are.
