    摘要: An improved punching tool (1) has a lower tool (3), which is subdivided into a lower tool base plate (7) and a lower-tool operative part (8). The lower tool base plate (7) has a receiving face, with which uniform base areas of a plurality of lower-tool operative parts (8) are associated. The dividing place between the lower-tool operative part (8) and the lower tool base plate (9) is disposed such that all the workpiece-specific designs are present exclusively on the lower-tool operative part (8), while the lower tool base plate (7) is the same, without change, for all workpieces to be machined.

    摘要: A punching tool for green sheets or similar sheet-like work-pieces having a support plate with punched holes (7), and a holding-down plate disposed above the support plate and containing stripper openings (24). Operative portions (23) of dies (8) extend through the stripper openings (24) and are guided therein. The operative portions (23) are formed in graduated form with a punching portion (26) of reduced diameter. Each punching portion (26) has a length that is less than the length of the stripper opening (24), and is located entirely in the stripper opening (24) when the die (8) is at its top dead center. A part (25) of the operative portion (23) protrudes into the stripper opening (24) to guide the die (8). The punching portion (26) is only approximately as long as required for the punching stroke of the die (8). The slight length of the punching portion (26) makes possible an especially slender punching portion, and thus the creation of especially small punched holes.

    摘要: The punching die of the invention has a head 22 held by positive engagement. The head 22 is held on the shaft 21 of the die 8 in that by means of plastic deformation, for instance by radial application of pressure, material is positively displaced radially inward, so that a protrusion 28 is embodied which rests over a large area on the wall of a recess 23. A more secure, more durable force transition is assured.

    摘要: A single stroke punch apparatus includes positive removal by compressed air of workpiece slugs which adhere to the punch. A die plate has a series of bushing receiving features formed from two concentric diameters. The die plate has provision for introducing a flow of compressed air into each of the bushing receiving features. A support bushing is mounted in each of the bushing receiving features and has a surface for support of the workpiece which is elevated with respect to the die plate. A slug removal bushing is also mounted in the bushing receiving feature and is pressed into the wall of the support bushing opposite the workpiece supporting surface to form a seal. The wall of the bushing receiving feature, the support bushing, and the slug removal bushing define a passage for the compressed air such that the compressed air impinges upon the punch directly adjacent the end wall of the support bushing to positively remove the punch slug which is adhered to the punch. The slug removal bushing has a passage for disposal of the punch slugs to which a vacuum may be applied to enhance slug disposal.
