Abstract
A stamping machine composed of a frame supporting a movable carriage having thereon a reciprocal operative punch and die for punching holes in material controllably fed to the die. The carriage movement is controlled by an eccentric mechanism within the confines of two barrier walls which limit the traverse of the carriage. The material is held firm by a clamp during the punching process and released for movement to permit the punch to pull the material a distance equal to the pitch of the stamping cycle, to await the next cycle of stamping.
Claims9
A material stamping machine comprising
- (a) a support frame,
- (b) a reciprocally movable carriage supported by said frame,
- (c) barrier walls having interfaces and restricting the reciprocal movements of said carriage,
- (d) one or more punch and die apparatus carried by said carriage,
- (e) power driving means including an eccentric for reciprocally actuating said carriage against the interface of the barrier walls in a pre-determined time sequence,
- (f) restraining means connected to said power means and disposed to engage the carriage after wall contact to restrict the movements thereof,
- (g) stamping means responsive to said eccentric power means for actuating said punch according to said predetermined time sequence, and
- (h) material clamping means responsive to the actuations of said stamping means for clamping and releasing material in the timed sequence.
