A stamping die includes an upper die member, a lower die member, and at least one guidance member operably disposed to guide relative movement between the upper and lower die members. The members are movable relative to one another in reciprocating motion along an axis to generate work-pieces. The guidance member has a guiding surface for guiding relative movement between the die members. The guidance member also has at least one wear indicator cavity recessed from the guiding surface. A depth of the wear indicator cavity corresponds to the extent of acceptable wear of the guiding surface. The cavity allows for visual inspection of the extent of wear of the at least one guidance member and thus obviates the requirement that the guidance member be removed from the stamping die for inspection.

The press device includes a press device body and moving bolsters. The press device body has a slide and a slide servomotor. The slide has upper dies attached thereto. The slide servomotor moves the slide up and down. The moving bolsters are able to move between a pressing position, which is a position on the inside of the press device body, and a die replacement position, which is a position on the outside of the press device body, and have lower dies disposed thereon. The moving bolsters have an electrical storage component, a travel motor, and wheels. The electrical storage component stores regenerative electrical power generated by the slide servomotor in the pressing position. Electrical power is supplied from the electrical storage component to the travel motor. The wheels are driven by the travel motor.

The assembly comprises a coupling for direct or indirect coupling the core rod (15) to the lower punch (12) of a powder press. The coupling is configured as a magnetic coupling and comprising two coupling elements (20, 30), the first (20) of which is actively connected to the core rod (15) and the second (30) of which is actively connected to the lower punch (12). The magnetic coupling comprises several permanent magnets (24a, 24b, 33a, 33b) arranged at each coupling element. These permanent magnets (24a, 24b, 33a, 33b) are arranged and adapted to each other such that when coupling the two coupling elements (20, 30) the first coupling element (20) is automatically rotated by the effect of the field lines of the magnets (24a, 24b, 33a, 33b) into a predetermined angular position relative to the second coupling element (30).

In order to shorten set-up times, a press for producing a molded part from pourable material, having an apparatus for driving a die comprising a cylinder unit having a cylinder housing and having a cylinder piston is proposed, wherein the cylinder housing is the actuator of the cylinder unit and the cylinder piston is the stator of the cylinder unit.

A cutting insert is provided, comprising a top surface, a bottom surface, a plurality of side surfaces spanning therebetween, and a cutting edge formed at an intersection of the side surface and a forwardly-disposed portion of the top the surface. It further comprises a cooling cavity projecting into the insert, a top end thereof being disposed further forwardly than an open bottom end thereof. The cooling cavity defines at least one molding axis such that a solid element having the shape of the cooling cavity and completely inserted therein may be retracted intact therefrom along a linear path parallel to the molding axis. A circumscribing portion is formed on the side surfaces encircling the cutting insert. The circumscribing portion is formed parallel to the molding axis and has a non-zero height along its entire extent. The cutting insert does not extend beyond the circumscribing portion.

Applying padding material around shaped cutting blades includes: receiving a blade shape diagram and a rule of blade; bending the rule of blade according to the blade shape diagram to produce the shaped cutting blades; and applying the padding material around the shaped cutting blades using the blade shape diagram to produce a padded shaped cutting blade, wherein the padding material provides a spring action to quickly detach the shaped cutting blades from a plate matter.

In a powder press, a spacer that is effective between a die plate and an opposite yoke is integrated into the die plate, particularly if the die plate is provided in an adapter, thus increasing the reliability of set-up processes.

An anvil including a hard phase and a metal matrix in which the hard phase is dispersed, a concentration of the metal matrix phase varying according to a concentration gradient, is disclosed. The anvil may be used in a high pressure press. Methods of making an anvil including forming a hard phase dispersed in a metal matrix phase, a concentration of the metal matrix phase varying according to a concentration gradient, are also disclosed.
