Abstract: A system is provided for forming shapes and contours in a metal workpiece, comprising: a laser system that is capable of producing a series of laser pulses, wherein each laser pulse of said series of laser pulses has an energy within a range of 10 J to 100 J per pulse, wherein said each laser pulse has a pulse duration within a range of 10 ns to 20 ns and a rising edge that is less than 1 ns; a layer of material that absorbs light for fixedly attaching to a metal workpiece and comprising polyvinyl acetate of polyvinyl chloride plastic; means for flowing a thin layer of water over said layer of material; and means for imaging the near field of said each laser pulse to a spot size on said layer of material so that said series of laser pulses will generate compressive stress on the surface of said metal workpiece until a desired shape is formed therein without inducing unwanted tensile stress at the surface of said metal workpiece.

Abstract: PURPOSE: To press a sheet metal parts in one process by setting a sheet metal blank to a forming tool, increasing the pressure step-by-step, and repeating the after-flow of the blank into a recess of the forming tool while cutting the blank. CONSTITUTION: A sheet metal blank 10 is set to a forming tool 1, an edge part indicated by the arrow A of the sheet metal blank 10 is cut in the first stage to form a formed blank 10. The pressure P on the sheet metal blank 10 is increased, and after-flow is achieved into a recess of the forming tool 1. In the next stage, the formed blank is semi-cut at a deeper position indicated by the arrow B of the forming tool 1. The forming blank 10 is further after- flowed in the recess and an undercut part, and the pressure P is increased to the final stage. A work is finally formed, drilled and seamed.

Abstract: PURPOSE:To increase the efficiency of takeout and insertion of a work and to make titled device simple and cheap, by providing a frame separated into plural parts in a holder fitted to a forming die the inside of which is connected to a high liquid pressure generator by leaving a space and allowing free sliding. CONSTITUTION:In forming, a frame 6 and an upper frame 14 are pulled upward by a cylinder rod, and a work is enclosed in a forming die 2. When the frame 6 and frame 14 are lowered after surrounding the die 2 with a holder 5, the frame 6 comes into contact with the holder 5 successively from upper part and downward movement is checked. The holder 5 is fixed at each fitting position, that is, at an interval in the vertical direction. When the frame 6 goes up and down, an interval adjusting piece 10 which was turned outward is inserted between frames 6. When impact liquid pressure of the work by a liquid pressure generator 17 in a liquid pressure working chamber 1 is completed, other frames 6, 14 are superposed on the lowermost frame 6. Fitting with the holder 5 is released by raising, and the product is taken out.
