Abstract: A process for manufacturing holes on the circumference of a hollow section situated in an internal high pressure forming tool uses the action of a punch integrated in the forming tool. A desired breaking point is formed on the hollow section, which follows the edge contour of the operating face of the punch; and after the withdrawal of the punch, the hollow section material surrounded by the desired breaking area, acted upon by internal high pressure, is extracted from the hollow section from the inside to the outside, forming a hole. In order to produce holes on the circumference of hollow sections, in which the shape of the outer circumference of the hollow section is maintained, the wall of the hollw section is weakened to form an unstable thin area. The punch penetrates into the wall of the hollow section at an internal high pressure which corresponds to the forming pressure for forming a hollow blank inserted in the forming tool.

Abstract: Method and apparatus for forming unobstructed holes in a hydroformed metal part employs a punch having a peripheral side conforming to the desired hole shape and an end face having a central cutting edge with a high point that contacts on closure of a hydroforming die with an unsupported wall section of the part initiating a stress riser therein. During forming of the part, the hydraulic pressure forces the above wall section outward against this high point increasing the magnitude of the stress riser. The punch is advanced while maintaining the hydraulic pressure causing the above high point to fracture this wall section at the stress riser and the above cutting edge to then split and cut this wall section to form oppositely facing cut edges in this section. Simultaneously, oppositely angled cutting edges at opposite ends of the central cutting edge and at the punch end face periphery then cut this wall section in directions away from the oppositely facing cut edges to form oppositely extending slugs.

Abstract: A pipe punch apparatus which generally comprises a punch housing, a punch means situated within the punch housing, and a collar. The punch housing is connected to a bi-directional hydraulic fluid pump means. Depending on which direction the pump is set, the pump releases fluid into the punch housing which causes the punch means to either extend from the punch housing or retract into the punch housing. The collar is connected to the punch housing by a connecting means so that a notch within the collar receives the punch means when the punch means is in the extended position. The parts are also relatively situated so that positioning the punch housing within a pipe will cause the collar to be located exterior to the pipe. Thus, as the punch means moves from its initial retracted position to its extended position, it will also punch a hole through the pipe.

Abstract: A metal tube is cold formed into a stamped member by filling the tube with a liquid change-of-state material, freezing the change-of-state material, sealing the tube containing the solid change-of-state material, and stamping the tube in a die. The change-of-state material compresses during the stamping step to force the walls of the tube to conform to the die cavity, eliminating the need to pressurize the tube prior or subsequent to stamping. Additionally, the solid within the tube provides support to the wall of the tube during a piercing step to form a hole in the tube having less deformation surrounding the hole than a comparative tube pierced without having the solid fill. After the stamping or piercing steps, the change-of-state material is melted and drained from the tube. Further, a tube is pierced by forming an outwardly bulged area and piercing the tube in the outwardly bulged area while simultaneously depressing the tube to substantially flatten the outwardly bulged area.

Abstract: A process for cutting hollow molded plastic parts uses two knife cuttings in sequence.
