Abstract
A device by which thin-walled materials, such as labels and flat lids for containers, can be punched in micro or small quantities. The device includes a band steel cutting edge (11) that is elastically mounted in the punching direction. The matrix is likewise elastically held on the matrix plate perpendicular to the punching direction by virtue of a matrix seat (33) fastened to the region in the matrix plate (27) that is adjacent to the opening (29). On the matrix seat, an elastically deformable intermediate plate (47) is placed, and the matrix (55) is placed on the intermediate plate.
Claims18
A device for punching thin-walled materials, comprising labels and flat lids for containers in small quantities, comprising a punching plate (1) for receiving a blade (11, 61);
- a matrix (55) on a matrix plate (27);
- wherein the blade (11, 61) and the matrix (55) are supported in a punching machine in a fixable and mutually displaceable fashion, in order to punch labels and lids comprising paper, plastic, metal, or a laminate from a material tape guided between the blade and the matrix;
- the matrix plate (27) comprising a recess (29) for guiding the punched out work pieces therethrough;
- a matrix seat (33) is fastened on an edge section of the matrix plate (27) abutting the recess (29);
- an elastically deformable intermediate plate (47) rests on the matrix seat (33);
- and
- the matrix (55) rests on the intermediate plate (47).
