Abstract
A header machine for drilling specified hole patterns in pipe and for cutting the pipe to a specified length to form headers for use in heat transfer products. The header machine includes hold clamps for selectively holding the pipe during the processing of the pipe and feed clamps for selectively holding the pipe during the feeding thereof through the header machine. The feed clamps are mounted on a feed carriage which is movably mounted for movement forwardly and rearwardly. The feed carriage is driven by a stepper motor operably coupled to the feed carriage for moving the feed carriage and the pipe endwise to various drilling positions. The header machine also includes a spud drill for drilling spud holes in the pipe, a connection drill for drilling connection holes in the pipe, a circular saw for cutting the pipe to a specified length, and provisions for making double circuit patterns of the spud hole. The various movements of the components of the machine are computer controlled and with data concerning the parameters of the header to be processed being entered by the operator into the keyboard of the computer which automatically writes a program for controlling such movements of the components.
