A nut forming machine of the conventional cold nut forming type employing a frame body mounting a crank shaft; a power source and belt drive means; a ram carrying first, second, third stage punches and a piercing punch; respective cooperating die sets; punch out means; rocking means; stock feeding and blank cutter means; transfer clamp means; and a cut off base mounting a slide block for actuating the blank cutter wherein (1) the ram is connected at its laterally opposed ends by respective crank arms mounted through spherical bearings on the crankshaft which in turn is mounted by spherical bearings in the side walls of the frame body; (2) the cut off base is integrally cast with the frame body and provided with slide surfaces in the form of replaceable slide plates; (3) the lateral spacing of the die holes and cooperating punches of the several forming stages and the lateral spacing of the blank cutter from the first forming stage are equal enabling the employment of a simple drive link connected to the slide block of the cutter and the clamper of the transfer clamp means to effect timed driving of the latter means; and (4) the die holes, conventionally provided in the frame body end wall, are formed in replaceable bushings mounted in bushing holes in the frame body.
CROSS REFERENCE TO RELATED APPLICATION
This is a continuation-in-part of application Ser. No. 401,419, filed Sept. 27, 1973, and entitled NUT FORMER now abandoned.
A forming machine includes a first transmission mechanism connected to a cutting mechanism and a conveying clamp mechanism, a drive mechanism for driving the first transmission mechanism; and a second transmission mechanism driven by the drive mechanism for driving a feeding mechanism. The second transmission mechanism includes a driven wheel driven by the drive mechanism, a first swing member connected to the feeding mechanism and confronting the driven wheel, an eccentric pin projecting axially from the driven wheel and connected slidably to the first swing member. The eccentric pin slides relative to the first swing member while rotating along with the driven wheel so that the first swing member is swung to and fro in a cycle motion and completes one cycle for each revolution of the eccentric pin.
