    Abstract: A high-tolerance molding device that uses a pulling technique to quickly form a desired elongated hole in a workpiece such as a pipe or a sheet with little material loss, due to the use of single-piece molding, while preventing material degradation. The workpiece is provided with a pilot hole that is smaller than but roughly concentric with the desired elongated hole. This molding device includes a power-coupling arm that can be inserted into the pilot hole; a control unit that controls the movement of the power-coupling arm; and a molding plug that is prepositioned on the opposite side, with respect to the power-coupling arm, of the surface of the workpiece in which the pilot hole is provided.

    Abstract: A punch tool is disclosed for puncturing the walls of heat exchanger tubes when they become worn in order that the tubes may be repaired. Said tool comprises a hardened, longitudinally drilled, steel rod that is able to fit within the heat exchanger tube. A piston with a cutting bit is fit within a milled slot that communicates with the longitudinally drilled hole of the hardened rod. Once the tool is inserted into a tube to be repaired hydraulic pressure is applied and the piston is forced outward thereby puncturing the tube.

    Abstract: The muffler has an outer shell filled with fiberglass wool around a central core tube which conveys the exhaust gases. The core tube is punched from the inside to form a spiral pattern of holes having gas deflecting tongues which project outward in circumferential directions opposed to the direction of the spiral. When the muffler is to be used on an engine producing a stream of exhaust gas having clockwise rotation in the core tube, the spiral pattern of holes is clockwise and the gas is discharged from the holes in counterclockwise directions. For a counterclockwise rotating gas stream the spiral pattern of holes is formed in counterclockwise direction and the tongues deflect the gas from the holes in clockwise directions. The holes are punched and the deflecting tongues are formed by a radial punch which reciprocates through a guide hole in a support tube. The punch is mounted on a crankshaft which rocks the punch back and forth as it is projected and retracted. When a core tube is placed on the support tube the rocking motion of the punch rotates the core tube to properly space the holes circumferentially. By slowly moving the core tube axially, the desired spiral pattern of holes is produced. The direction of the spiral, as a right-hand or left-hand thread, is determined by the direction of rotation of the crankshaft.

    Abstract: The purpose of the present invention is to provide a high-tolerance molding device that uses a pulling technique to quickly form a desired elongated hole in a workpiece such as a pipe or a sheet with little material loss, due to the use of single-piece molding, while preventing material degradation. The workpiece is provided with a pilot hole that is smaller than but roughly concentric with the desired elongated hole. This molding device is characterized by the provision of: a power-coupling arm that moves in a direction roughly perpendicular to the surface in which the aforementioned pilot hole is provided and can be inserted into the pilot hole; a control unit that controls the movement of the power-coupling arm; and a plug that is prepositioned on the opposite side, with respect to the power-coupling arm, of the surface of the workpiece in which the pilot hole is provided. The plug can engage with and move together with the arm.
