Definitions
- the invention relates to a device for cutting of roof slabs consisting in particular of natural slate.
- Roof tiles are used for high-quality roofing made of natural slate, which is used in the usual treatment Have lifespan of over 100 years. Such roof tiles give the roof a good appearance and close the formation of disruptive coverings largely.
- Roof tiles Natural slate is made by companies that use natural slate Dismantle in open or underground mining, split into slabs and delivered in a specified size. Made of natural slate existing roof tiles are exclusively from a roofing specialist company on the roof in predetermined patterns misplaced and nailed. It always happens before that individual roof tiles in their footprint reduced Need to become. This is done using a so-called Slate hammer by hand. Such downsizing from Existing slate roof tiles is proportionate cumbersome and time consuming.
- the invention is based on the object of a device to show with which in particular consists of natural slate Roof tiles in the shortest possible time and at the same time Reduction of breakage can be reduced or cut can.
- the device should also ensure that the cut edge looks like a break edge like it in the case of a roof panel when machining by hand a slate hammer is produced.
- the device according to the invention is used to achieve this object from a driven, lifting and lowering ram for exchangeable mounting of a rectangular cross section and an inclined lower surface in the cutting direction separating stamp and two in the cutting direction, below and at a distance on both sides of the Separating stamp of fixedly arranged separating edges.
- the commercially available roof tiles especially made of natural slate, reduced very quickly and with an extremely low breakage rate or be tailored.
- the cutting edge shows breaking edge-like appearance, which gives the impression as if she worked with a slate hammer as before has been.
- the device according to the invention also offers also the advantage that, for example, a commercially available Roof plate can be divided and both parts, provided they have the size still required, can be used. Thereby the breakage or waste is further reduced.
- a device 1 for cutting of roof slabs 2 made of natural slate in elevation shown which consists of a drive part 3, that the slightly modified part of a known per se electric tin snips.
- the only partially shown Drive part 3 is in a not shown Rack mounted or releasably attached, which is a U-shaped Has shape.
- the drive part 3 is from the top Thigh end of the U-shaped frame added while at the end of the lower leg of the U-shaped frame only one indicated work table 4 is formed.
- the work table 4 has a perpendicular to the plane of the drawing running recess 5, the through on both long sides Cutting plates 6, each with a separating edge 7 is limited. Between the two cutting plates 6 is a perpendicular to Gap 8 running in the plane of the drawing, its width is about 10 mm in the selected embodiment.
- Knife-acting separating stamp 9 which is by means of a screw 10 releasably on an up and down movable plunger 11 of the drive part 3 is attached.
- the separating stamp 9 points in this embodiment, a width of about 5 mm and a Length (Fig. 2) of about 20 mm.
- the lower surface 12 of the Separating stamp 9 is inclined in the cutting direction, the separating stamp 9 in FIGS. 1 and 2 each its occupies lowest position.
- the stroke of the plunger 11 and so that the separating stamp 9 is about 3 mm.
- the separating punch 9 Due to the relatively short length of the separating stamp 9 curves can also be cut with this device.
- the separating punch 9 be trained longer.
- the lower surface 12 of the separating stamp 9 should have an inclination of at least 3 °. Inclinations Avoid over 20 ° as much as possible, because then a relative high feed force exerted by hand for the Moving the roof panel 2 is required.
- the gap 8 and the width of the separating stamp 9 make sure that the gap 8 on each side about 1 to 3 mm wider than the width of the separating punch 9.
- the total width the gap 8 is thus 2 to 6 mm larger than the width of the separating stamp 9. It is possible to drive the part 3 to design differently or the drive part of another Machine tool to use which is a reciprocating Has pestle.
- the device described is of course also Can be used to cut roof slabs from artificial slate.
- the sheet metal shears used in the exemplary embodiment can by another electrical or pneumatic drive unit can be replaced with a reciprocating plunger.
