Definitions
- the invention relates to a punching device for producing ceramic plates according to the preamble of claim 1.
- a punching device of the type mentioned in which a press plate with a profiled surface is provided, which is designed so that the edges of the plate are chamfered during punching, so the press plate acts as a notching device.
- the disadvantage here is that a distance must remain between the notching tool and the punching knife, which creates a beard on the chamfered and punched plate edge, which becomes larger when the tool is used, and that clay is squeezed between the notching and punching tool, which wedges the tools together, especially when the clay dries.
- the notching tool is expensive.
- the object of the invention is therefore to design a punching device of the type mentioned in such a way that as little clay as possible is squeezed between the punching knife and the press plate, so that there is no beard on the plate edge and the device remains smooth-running.
- the advantages of the invention are, in particular, that the notching tool is inexpensive and can be adjusted when worn, that no sound is squeezed between the notching and punching knives and that the device remains smooth-running.
- the punching tool 1 consists of a knife frame 2 and punching knives 3 with which plates 4 are cut out of a clay strand 5.
- a notch and hold-down device 6 with notch tools 8 which are adjustably movably mounted on the press plate 7 to the punch knives 3 and which consist of horizontally adjustable abutments 9 and sheet-shaped notch knives 10 which are flush with the punch knives 3 at an angle of Chamfer 11.
- the punch 1 is lowered until the notch and hold-down device 6 rests on the plate, the notch 10 being used to chamfer the cut edge, while the punch 3 is pressed further through the strand until the plate is punched out.
