Definitions
- the invention relates to a device for cutting flexible, flat workpieces with a workpiece support, one to the workpiece support adjustable, at least one knife having cutter head and with a knife head associated, laterally next to the knife provided and this opposite to the workpiece support adjustable Stripper plate.
- a cutter head with at least one Inserting a knife the workpiece receiving on a workpiece support is adjustable and relative to the workpiece support along a predetermined Cutting process is performed.
- the correct position of the workpiece on the workpiece support is assigned by a cutter head Sliding shoe, which not only the workpiece against the workpiece support holds, but also for keeping a predetermined Cutting depth ensures that by moving the shoe against the Knife can be adjusted perpendicular to the workpiece support.
- the invention is therefore based on the object, a device for Cutting bending soft, flat workpieces of the type described in such a way that one of the respective material of the workpiece largely independent, accurate cutting enabling bracket of the workpiece on the workpiece support can be ensured without To fear damage to the workpiece surface.
- the invention solves the problem set by the fact that the hold-down from at least one pressure roller forming a conical rolling surface with a transverse to the cutting direction, inclined relative to the workpiece support Axis exists.
- At least one pressure roller as a hold-down can first a sliding movement between the hold-down and the workpiece be avoided, whereby the due to such a sliding movement at a Sliding occurring difficulties are prevented.
- the due the conical rolling surface different peripheral speeds of Pressure rollers have no practical significance in this context.
- the conical rolling surface conditional inclination of the pressure roller axis is required to hold the hold down in the smallest possible lateral distance to be able to start from the knife to the workpiece. Because of the rolling the conical rolling surface of the pressure roller on the workpiece surface in the immediate Near the knife engagement the workpiece in the area of the knife engagement is kept pressed cut to the workpiece support, is Such workpiece holder for workpieces made of different workpieces equally suitable.
- the pressure roller can be pot-like be formed, wherein the pot wall open towards the knife the Rolling surface forms.
- This cup-like design of the pressure roller allows a partial Recording the cutter head in the pot area of the pressure roller, so that the Pressure roller near the knife can be placed on the workpiece.
- the inventive Pressure rollers are used advantageously. It's just a heater for the pressure roller or the pressure rollers at least in the area of Rolling surface to provide over the rolling surfaces, the heat transfer to the to ensure thermally treated cutting edge area.
- the storage of the pressure roller or pressure roller pair can be different Be solved constructive way.
- a Housing which can be connected from one to the cutter head Support ring and a bearing ring in the support ring against spring force axially displaceable bearing ring for receiving the pressure roller or pressure rollers.
- On the Support ring is the housing for the pressure roller or the pressure rollers coaxial with Knife head attached to this, so that upon rotation of the cutter head for knife guidance along a given cutting process the respective Pressure roller is taken and their required for the workpiece holder spatial assignment to the knife maintains.
- the bearing ring relative to the support ring is the respective pressure load of the workpiece predetermined by the pressure rollers.
- a workpiece support 2 usually a cutting table, provided, opposite to a cutter head 3 along a predetermined cutting process can be moved.
- This knife head 3 is provided with at least one blade 4, which is suitable for cutting Grooves or bevels as a peeling knife or for cutting the workpiece 1 may be formed as a separating knife.
- New compared to conventional Knife heads 3 is the intended hold-down for cutting fair Pressing the workpiece 1 to the workpiece support 2 in the form of two pressure rollers 5, whose axes 6 extend transversely to the cutting direction and are inclined relative to the workpiece support 2.
- the axes 6 of the pressure rollers 5 are held in a bearing ring 7 of a housing 8, in addition to the bearing ring 7 comprises a connectable to the cutter head 3 support ring 9.
- the Housing 8 is thus coaxial with the axis of rotation 10 of the cutter head 3 at this attached, so that the pressure rollers 5 to the knife guide along the predetermined cutting process required rotational movements about the axis of rotation Join in 10
- the bearing ring 7 is guided axially displaceably within the support ring 9, with the help of engaging in axial slots 11 of the bearing ring 7 Guide pin 12.
- the bearing ring 7 is thereby by compression springs 13 held in a stop position from which the bearing ring 7 in the housing. 8 can be inserted.
- the in a receiving bore 14 on the bearing ring. 7 supported compression springs 13 find their other abutment in pressure plates 15, which are inserted in circumferential slots 16 of the support ring 9 and axial bolts 17 to guide the springs 13 wear.
- the pressure rollers 5, which rotate freely in the illustrated embodiment are stored, but also via controlled drives depending on the respective Intersection can be driven, roll under exercise a corresponding pressure force over conical rolling surfaces 18 on the workpiece 1, which is about this pressure load immediately to the side of the Knife 4 is cut down to the correct level on the workpiece support 2.
- the pressure rollers are the fifth cup-shaped, wherein the pot wall 19 of the against the knife 4 out opening pots form the rolling surfaces 18.
- the pressure rollers 5 could at least be heated in the region of the rolling surfaces 18, about the pressure rollers. 5 to suspend the cut edges of a heat treatment.
- the Contact pressure of the pressure rollers 5 to the workpiece 1 via a control device be controlled according to the respective requirements. The mechanical Prerequisites for this are yes by the axial displacement of the bearing ring 7 in the housing 8 given.
