摘要： A method and apparatus for piercing a pair of aligned holes through both sides of a tube combined with the process of hydroforming the tube to final shape. After the tube is expanded and internally pressurized between upper and lower dies, a punch is driven forcefully through a cross passage in the die and through both walls of the tube, one after the other. The end of the punch is bored out sufficiently to leave a sharp edge that cuts a first slug, and the first slug is wedged into the end of the punch. The opposed wall of the tube is backed by a female die button with a cylindrical cutting edge concentric to, and equal in diameter to, the end of the punch. The end of the punch enters the die button to cleanly shear out a second hole, pushing a stack of two slugs into the die button. A pressure feed orifice properly located enters the still pressurized tube at this point, feeding positive pressure to the punch bore to blow the slugs off and out of the die button.

摘要： A tubular member is manufactured in a hydroforming and hydroshearing apparatus. A substantially right circular cylindrical workpiece is placed in a die and pressurized to hydroform a substantially rectangular tubular product. The workpiece is presheared during the pressurization period and is fully sheared during the withdrawal of a plurality of plunger members while the internal pressure is maintained. The plunger members are positioned in the die by respective power cylinders which control the withdrawal thereof.

摘要： A method of joining tubular members together includes the steps of providing an internal tubular member, providing an external tubular member, and heating the external tubular member and/or cooling the internal tubular member. The method also includes the steps of joining the internal tubular member and second tubular member together to form an overlap region of a joined tubular member, and positioning the joined tubular member between open die halves mating with one another to define a tubular cavity portion. The method includes the steps of progressively closing the die halves to progressively deform the joined tubular member within the tubular cavity portion. The method includes the steps of applying hydraulic pressure to expand and conform the joined tubular member to the tubular cavity portion. The method also includes the steps of separating the die halves and removing the expanded joined tubular member from the die.

摘要： A multi-section support rail has a first section with an outer circumferential wall, a parallel inner circumferential wall and a transverse web extending longitudinally therealong, a second section hollow tubular section with an outer circumferential wall and a parallel inner circumferential wall. The outer circumferential walls are substantially identical dimensionally. The sections are joined at mating surfaces,. The joined sections are pre-bent at the second section and then hydroformed to a final desired shape. The transverse web retains the extruded dimensions throughout the hydroforming process.

摘要： A method for cutting an "O" ring retention groove around the cutting edge of a hydropiercing die button. A groove machining tool is given a convex curved end surface the radius of which is slightly less than or, at most, substantially equal to the tightest concave radius that the end surface will have to sweep through as the groove is cut. Consequently, an accurate, slightly curved groove bottom surface is created for the "O" ring, while the machining tool will not bind as it moves through the tightest concave portion of the cutting path.
