    摘要: A die stamping system includes opposed die members (10, 11) which clamp a metal workpiece (W) to be shaped, cut or pierced after which the die members are moved away from one another and a part is subsequently ejected, wherein the ejector is controlled for a selected delay time by a plurality of cylinder assemblies (16) mounted in a manifold (17) so that they are connected to a fluid source of high pressure (53) and to a source of hydraulic pressure (53). Each cylinder assembly (16) includes a piston (26) associated with, and exposed to the fluid pressure in the manifold. The cylinder assemblies (16) are connected to a single hydraulic valve (50) which has associated therewith an accumulator (53) and which is operated simultaneously to actuate the cylinders. The hydraulic lines to the cylinders (16) are provided in the manifold (17).

    摘要: The device for invalidating plane objects, in particular defective products in the securities sector, such as banknotes, notes of value, etc., by perforating means, has a horizontal base plate (9) onto which the objects (14) to be invalidated are placed, and die plates (13, 17, 18) which are vertically movable and parallel to said base plate, as well as a drive mechanism by which the die plates can be displaced up and down. The perforating means comprise at least one cutting bushing (23) with a hollow paper drill (19) interacting with the cutting bushing in order to displace the paper scrap in the paper drill.

    摘要: An improvement to a stamping press having a blanking punch and die combination comprising a blanking die (52) defining an opening, a cooperating blanking punch (50), dimensioned closely to mate with the opening wherein the die edge defining the opening is radiused to cause metal flow, a stock engaging shedder (74) displaceable within the die opening to engage and clamp stock (122) and a stripper (86) encircling the blanking punch (50) and displaceable therealong to remove surplus stock after a blanking operation. The improvement comprises the stripper (86) being disposed to engage and clamp stock (122) being punched by the blanking punch and die. Additionally, there is a variable pressure source (104, 108, 110, 120) connected to cause the stripper (86) to engage and clamp the stock (122) during punching of the stock under a pressure low enough to permit the stock to flow away from the blanking punch (50) and high enough to prevent the stock from bending and to cause the stripper to (86) exert sufficient force on the stock (122) following punching of the stock to strip the stock from the blanking punch (50). The preferred variable pressure source comprises a piston (104) connected between the stripper (86) and a fixed point (94) and a variable pressure source (110) operably connected to the piston. The variable pressure can be set for different types and thicknesses of material.

    摘要: A heated aluminium log which is to be sheared is inserted through a stationary die 11 and a movable die 12. A clamp (25) of the stationary die is then moved towards an axis of that die to clamp the log against a diametrically opposite portion of the internal surface of the die. Opposite members (15,16) of the stationary die are then moved towards each other in a direction perpendicular to the direction of movement of the clamp, to limit expansion of the sheared log.
