Abstract

601,977. Forging nuts; shearing. NATIONAL MACHINERY CO. March 19, 1945, No. 6870. Convention date, Aug. 3, 1944. [Class 83 (iv)] A method of making nuts and the like includes the step of confining the blank in a die and upsetting it into a dished or concavo-convex form so as to force one end of the side wall of the blank laterally against the side walls of the die. Rod stock S is fed through an opening 11 in the bed frame of the machine into a sleeve 14, Fig. 1, to an extent determined by a plunger 16 abutting a stock gauge 18. The sleeve 14 which is integral with an arm 13 is moved to shear off the projecting portion of the stock and to carry the blank to a position in front of a die of circular cross-section, but with chamfered bottom edges. A punch carried by a reciprocating header engages the outer end of the plunger 16, thus forcing the blank into the die to shape it as shown in Fig. 2a. The blank 25 is then ejected, turned over and forced under comparatively light pressure into a hexagonal die so as to form a partially hexagonal blank. After ejection, the blank is again turned over and is forced into another hexagonal die 33, Fig. 4, by a punch 38. The bottom of the die and the nose of the punch have substantially parallel conical faces 34, 40, respectively, by which the blank is given a dished or concavoconvex form. A nose 37 at the end of a knockout pin 36 enters the other end of the blank and spreads the metal radially outwards to fill the corners of the die. On ejection, the blank is again turned over and is forced by a punch 50 into a die 46, Fig. 5, in which the blank is flattened, thus forcing the other end of the blank into close contact with the corners of the die. This die also has a bottom wall 47 shaped to form a washer face on the blank, while the punch has a portion 51 which flattens the inner portion of the outer surface of the blank, but leaving it slightly convex at the outer edge. For the next operation the blank is supported in a die 61, Fig. 6, and pierced by a punch 69 having a working end portion 76 and a smaller relieved portion 77. On the retraction of the punch the end portion 76 ejects the blank from the die and then withdraws into a sleeve 72 which strips the blank from the punch. Specification 426,845 is referred to.
