A punch press tool for stamping successive multicharacter impressions into a workpiece such as a piece of steel, sheet metal, or other workpiece, includes a guide body in which a stamp driver is slidably mounted for being driven downwardly toward the workpiece by a punch press ram which is a standard part of a high speed commercial punch press. A multicharacter marking stamp is supported at the lower end of the stamp driver for reciprocal movement therewith. The marking stamp includes multicharacter wheels that are rotated automatically during operation for advancing characters in sequence responsive to the movement of a character advancing arm. At least one character stamp operating lever is operatively associated with the punch press tool for articulation responsive to motion imparted to the tool by the ram. The lever has an operating element that is operatively associated with the character advancing arm of the multicharacter stamp for indexing the arm to enable successive characters thereof to be placed in an operating position responsive to a stroke of the punch press ram.

Punch press tool for stamping successive multicharacter impressions into a workpiece

A tapping tool having a guide body, a driver for longitudinal movement of a tap within the guide body, and a pump for lubricating the tap. A keyway in the outer body of guide body mates with an indexing key in a rotatable indexing holder of a turret press, which causes the guide body to rotate in sync with the turret press. A driver cylinder is centrally disposed in the guide body. The driver is adapted for sliding, mating engagement within the driver cylinder. A chamber in the lubrication pump holds the lubrication which is ejected by the pump onto the tap. Lubrication is ejected onto the tap through a normally closed ejector inlet that is opened by downward movement of a plunge pin against the lubrication in the chamber. The ejector is sized to restrict the flow of lubrication from the ejector outlet, which creates back pressure in the lubrication chamber. The back pressure forces a ball to close the lubrication conduit when the plunge pin moves downward.
