摘要： At least three sets of upper and lower dies are mounted on the upper movable plate and base plate. A work pick-and-place device is mounted on the lower movable plate provided to be reciprocated in the horizontal direction and reciprocated in the vertical direction so as to progressively transfer parts on the lower dies. At least three part pick-and-place devices are radially mounted on the base plate. Each of the part pick-and-place devices is provided to be reciprocated in the horizontal direction and reciprocated in the vertical direction so as to feed parts one by one to a corresponding lower die.

摘要： An electromagnetically-driven punch press has an electromagnetic drive thrust motor comprising a fan-cooled solenoid winding and movable armature mounted in elevated location for isolating the magnetic circuit from the tooling to avoid tool magnetization and isolating winding heat from tooling for stabilizing tool dimensions. Stroke length, "open" height and "shut" height are conveniently adjustable; and tool performance is optimized by adjusting armature-thrust versus travel. Four-way access to tooling enables convenient material feeding and handling, including multi-direction or multi-layer feed. Scrap pieces are freely downwardly ejected. Multiple electromagnetic drives are mountable side-by-side at the same elevation, or they are stackable at multiple levels for increased power or for tailoring force-versus-distance relative to materials being worked. Materials-handling and/or tool-handling robots or pneumatic actuators can be installed on an elevated platform. The electromagnetic drive is removable and interchangeable among multiple die sets for easy tooling change-over among various production runs. Thus, "tooling set-up" by skilled machinist need be performed only once for each die set until worn dies require sharpening. A resilient upwardly biased shuttle pole-piece boosts available energy by extending upwardly into the winding opening. Ball-bearing bushings carry the movable tool and anti-skid supports prevent ball bearings and their cages from skidding downwardly when the moving tool impacts against the work material. Adjustable resilient cushioning arrests tool travel for minimizing "tool whip" and tool wear at the end of the work stroke.

摘要： Una máquina formadora de cuerpos (15), que transforma copas metálicas de poca profundidad (16) en cuerpos de lata alargados, donde incluye un ariete recíprocamente (20) el cual, durante su carrera de avance, empuja las copas a través de un conjunto de estampas circulares graduadas (22). Limpiadores con forma de anillo (83, 84, 85) se acoplan con la superficie cilíndrica externa (70) del ariete y están ubicados o dispuestos de modo que el primero de los limpiadores raspa el refrigerante de la herramienta del ariete, conforme esteultimo se mueve hacia atrás, y el segundo de los limpiadores raspa el fluido de cojinete hidráulico del ariete, conforme este ultimo se mueve hacia adelante. Los limpiadores están provistos con aletas flexibles (89) que están en acoplamiento por friccion con el ariete, a una presion relativamente baja, lo que resulta solamente en aumento de temperatura muy bajo que incrementa la vida util de los limpiadores, a velocidades de produccion de aproximadamente 400 latas de 2.50 pulgadas (63.5 mm) de diámetro por minuto.

摘要： A press machine for operating a press die set has a receiver for supporting a bolster 77 on which a part of the press die set is mounted. Both the bolster and the receiver 72A have central opening through which pressings, pressed from a workpiece, may fall. The opening in the receiver has the minimum shape and area required for the free passage of the pressings. This enables the thickness and the rigidity of the receiver to be increased as compared to a conventional press.

摘要： The guide columns of the punch press are releasably mounted to the base plate. Guide sleeves project from the ram and the guide columns are guided inside of the these guide sleeves. The sealing between the guide columns and the guide sleeves is made by piston rings. Leakage oil is collected at the oil collecting ring and discharged through a transfer channel (11) located in the ram (2) towards an inner space of the guide sleeve. A horizontally mounted check valve is located in this oil transfer channel. The guide column includes a leakage oil channel which extends to the oil collecting space in the base plate. In operation oil present in the oil collecting ring is pumped into the oil collecting space due to the continously changing of the volume of the inner chamber such that no leakage oil can enter the punching work space. The check valve opens during the upwards movement of the ram and closes during the downwards movement thereof. Those sections of the guide columns which incorporate a sealing and guide function are surrounded by the respective guide sleeve at all operational positions of the ram and are accordingly protected against injury. By means of the above design a penetrating of lubricating oil into the punching works space is impossible and no large loss of lubricating oil is possible.

摘要： A bodymaker that transforms shallow metal cups into elongated can bodies includes a reciprocated ram which, during its forward stroke, drives the cups through a set of graduated circular dies. Ring shaped wipers engage the outer cylindrical surface of the ram and are arranged so that a first of the wipers scrapes tool coolant from the ram as the latter moves rearward and a second of the wipers scrapes hydraulic bearing fluid from the ram as the latter moves forward. The wipers are provided with flexible flaps that are in relatively low pressure frictional engagement with the ram resulting in only a very low temperature rise for the wipers to increase operating life thereof at production rates of approximately 400 per minute for cans of 2+E,fra 1/2+EE inch diameter.

摘要： The die assembly (2,36) comprises a die plate (7,46) having one or more die inserts (14,64,66,68,70,72) therein. The die plate (2,36) has a recess (10,58) within which the insert is positioned. The die opening (20,124,126,128,130) in the insert extends normally of the oppositely directed major surfaces (16,18) of the insert (14) so that the insert can be reversed. The original obverse surface (16) of the insert thus becomes the reverse surface and the original reverse surface (18) becomes the obverse surface. The necessity of sharpening the die insert in the conventional manner is thus eliminated. Also disclosed is an improved system for mounting die inserts in a die assembly.
