摘要： Four lever units are linked to the arrangement of connecting rods via a common bolt. Each lever unit drives one ram of the punch press. The rams are arranged in configuration of a square. This allows a much higher loading by off-center forces and the punch press can be designed for a given punch press output with considerably smaller dimensions.

摘要： A compact power hammer that can be used to drive post easily and safely by one person as well as for use with other impact tools. The invention is comprised of a cam (26) lifting a hammer (44) and dropping it onto an anvil (30). The impact on the anvil (30) is transferred to the post (56) or impact tool by way of the center tube head (58). The center of gravity of the impact device (10) is below and in the post or impact tool 56.

摘要： A high speed stamping and forming machine (10) is provided having a ram (34) capable of sustained high speed operation. The ram (34) is pivotally attached to a connecting rod (36) which is eccentrically coupled to a drive shaft by means of an eccentric (40) and hydrostatic bearing (50). The drive shaft (30) is journaled in hydrostatic bearings (84, 86) in the frame (12) of the machine. The ram reciprocates toward and away from a bolster plate (20) within a ram bearing (138) having hydrostatic bearings therein. A source of high pressure hydraulic fluid is interconnected to the hydrostatic bearing (50) of the eccentric coupling by means of a fluid coupling (350, 352) consisting of telescoping tubes, one end of which engages a spherically shaped seat (356, 358) in the frame (12) that is in communication with the high pressure fluid source and the other end of which engages a spherical shaped seat (354) in the moving connecting rod (36), which is in communication via a passageway (60) with the hydrostatic bearing (50). A main counterweight (142) is provided on the drive shaft (30) to counterbalance the effects of the reciprocating ram and a two shaft (166), counter-rotating weight system counterbalances lateral loads imposed on the machine (10) by the main counterweight. The bolster plate (20) of the machine is provided with a deep support structure (24) and surrounding concrete (26) to form a stable base (28) to reduce vibrations caused by the impact of the tooling with the strip of material being formed or blanked.

摘要： A laminated veneer hammerboard for a drop forge press comprised of a series of plies of hard, high density wood preferably of the order of a peeled hard maple veneer with the grain of at least most of said veneer plies running along its length, each of said plies of the hammerboard having a thickness in the range of 1/32" to 3/16", and glue deposited between the plies securing the plies together and providing a relatively large number of hard glue surfaces enhancing the wearability of the board, said plies having opposite vertical edges positioned for edgewise engagement with lift rollers on a drop forge press.

Vertical edges of each ply being disposed at opposite ends of the hammerboard rather than along the width thereof, thus enabling each roller to engage an outer side surface of the outermost ply on each side of the hammerboard rather than directly against opposite vertical edges of each ply.
