  • Patent number: 7918630
    Abstract: A material cutting machine has a tool mount support mounted for reciprocal movement and a tool mount supported by the tool mount support. A driver, such as a pneumatic cylinder, selectively advances and retracts the tool mount support. A control system is operatively coupled to the driver for setting the advancement force of the tool mount support when a tool supported by said tool mount contacts a workpiece, such as the edge or surface of a moving strip. In this way, the depth of cut of the tool is controlled by tool advancement force rather than by accurate positioning of the tool. In one embodiment, the tool mount support may have a head and a base and a resilient member resiliently coupling the head to the base to provide a damped resilience. With this embodiment, a transient spike in the reaction force which may result, for example, from a hard spot in the material, causes the tool to momentarily deflect.

  • Patent number: 5368218
    Abstract: A weld bead cutter mechanism continuously planes weld beads projecting from the seam weld zone of an electric seamed steel pipe. The weld bead cutter mechanism fits into an assembly line for manufacturing electric seamed steel pipe right after equipment which continuously molds sheet metal and welds the seam. The weld bead is planed off from the steel pipe by a planing blade, bent by a guide shoe fixed to the planing blade holder, and automatically guided through a groove in a bead guide to a rotary bead chopper. The weld bead is then chopped into small pieces as the rotary bead chopper chops it against a stationary blade. The distance between the planing blade and the rotary bead chopper is minimized by the use of the guide shoe and bead guide, which ensures a stable weld bead movement. The weld bead cutter mechanism operates without requiring manual guidance of the weld bead, which greatly reduces the risk of a labor accident.
