What reading level is Cold Heading book?
To quickly assess the difficulty of the text, read a short excerpt:
It con- sists of a mechanism that allows the knockout pin, against which the blank is forced during the heading operation to draw back after the blow is struck. This allows the metal to flow into the dies more freely on the second blow, and is especially desirable on such work as requires squares or shoulders underneath the head. By a proper knowledge of the use of this relief motion, a great many difficult jobs of heading can be accomplished with facility.
E. J. Manville Double-stroke Open-die... Cold-header Double-stroke cold-headers of the open-die type are the most compli- cated ot the ordinary run of heading machines, for in addition to the rise-and-fall motion for operating the punch block, provision must be made for opening and closing the dies. In Fig. 22 is shown the E. J. Manville double-stroke open-die header. This machine is made in four sizes; the one illustrated is the No. 4 machine which handles wire up to one-half inch diameter. This header is of the crank-operated type, and the wire enters through feed-rolls of the usual type and thence to its cut-off position between the square dies.
