Book Description
Excerpt from Machine Forging The upsetting and forging machine might be considered to a certain extent as a further development of the bolt and rivet making machine, which was originated almost a century ago; but forging machines are built much heavier than bolt and rivet machines and are designed especially to meet the demands in the production of difficult-shaped and heavy forgings. For the heavier types of machines, the base or main frame, as a rule, is made from one solid steel casting. A typical upsetting and forging machine designed for heavy service is shown in Fig. 1. The bed of this machine is made from one solid casting of semi-steel. In order to provide against breakage caused by accidentally placing work between the dies, upsetting and forging ma chines are usually furnished with various safety devices to prevent serious damage to the machine. The safety device in this machine consists of a toggle-joint mechanism for operating the movable grip ping-die slide. The gripping die slide A, Fig. 1, is operated by two cams B and C' on the main crankshaft D. Cam B serves to close the dies which grip the work; cam C operates the opening mechanism for the dies. These cams are in contact with chilled cast-iron rolls E and F carried in the toggle slide G. The automatic grip relief is controlled by the by-pass toggle H and heavy coil spring I. This toggle does not come into play until the strain is such that it would cause damage to the working mechanism of the machine, or in other words until the maximum power required to hold the movable die from springing away, ' is attained. The relief resets automatically on the back stroke of the machine, thus making a second blow possible without delay.

Book Description
Excerpt from Machine Forging Possibly the greatest advance made of late years in forging is the application of machine methods to the production of engine and machine parts. It is now possible to forge many parts from steel and wrought iron, which a few years ago could only be made from castings. This means a great saving of time and expense, as not only are machine forged parts much more rapidly made than those made from cast iron or steel castings, but they also cost considerably less to manufacture in large quantities. In the following, interesting examples of different types of upsets, bending and forming operations, etc., will be illustrated and described, together with a general description of the dies and tools used. This will give an idea of the remarkable possibilities of the upsetting and forging machine in its present-day development. The Upsetting and Forging Machine The upsetting and forging machine might be considered to a certain extent as a further development of the bolt and rivet making machine, which was originated almost a century ago; but forging machines are built much heavier than bolt and rivet machines and are designed especially to meet the demands in the production of difficult-shaped and heavy forgings. For the heavier types of machines, the base or main frame, as a rule, is made from one solid steel casting. A typical upsetting and forging machine designed for heavy service is shown in Fig. 1. The bed of this machine is made from one solid casting of semi-steel. In order to provide against breakage caused by accidentally placing work between the dies, upsetting and forging machines are usually furnished with various safety devices to prevent serious damage to the machine. The safety device in this machine consists of a toggle-joint mechanism for operating the movable gripping-die slide. The gripping die slide A, Fig. 1, is operated by two cams B and C on the main crankshaft D. Cam B serves to close the dies which grip the work; cam C operates the opening mechanism for the dies. These cams are in contact with chilled cast-iron rolls E and F carried in the toggle slide G. The automatic grip relief is controlled by the by-pass toggle Hand heavy coil spring I. This toggle does not come into play until the strain is such that it would cause damage to the working mechanism of the machine, or in other words until the maximum power required to hold the movable die from springing away, is attained. The relief resets automatically on the back stroke of the machine, thus making a second blow possible without delay.
