LAMINATED BOARD AND HAMMER COMBINATION FOR A DROP HAMMER FORGE

摘要

A laminated plywood 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, the edges of each ply 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 edges of each ply.
