摘要： According to an implementation a method for manufacturing a pedal for a motor vehicle is provided. The method comprising inserting into a hollow profile a flexible yet substantially incompressible retainer member and subsequently applying one or more forces to an external surface of the hollow profile to induce a change in shape of the hollow profile from a first shape to a second shape. The substantial incompressibility of the retainer member inhibiting deformations in the internal wall surface of the hollow profile as the one or more forces are applied to the external wall surface of the hollow profile so that the internal wall surface is substantially free of deformations upon the hollow profile assuming the second shape, the flexibility of the retainer member allowing it to bend in the direction of the applied one or more forces to accommodate a change in shape of the hollow profile from the first shape to the second shape.

摘要： A first mandrel segment comprised of first and second resinous sheets including proximal end portions vertically spaced from each other is initially inserted into a pipe having a weld seam extending longitudinally thereof. Since the first mandrel segment has a thickness smaller than an inside measurement of the pipe, the first mandrel segment can be inserted into the pipe without being caught by a bulged portion of the weld seam protruding inwardly of the pipe. After the insertion of the first mandrel segment, a second mandrel segment comprised of a third resinous sheet is forced into a spacing between the first and second resinous sheets. By thus forcing the third resinous sheet into the spacing, the first resinous sheet is pushed vertically to come into intimate contact with the bulged portion. The pipe having the first, second, and third resinous sheets thus inserted therewithin is then bent by a bender. After the bending of the pipe, the third resinous sheet is first pulled out of the bent pipe. The first and second resinous sheets are subsequently pulled out of the bend pipe.
摘要翻译：包括第一和第二树脂片的第一芯棒段包括彼此垂直间隔开的近端部分，最初被插入具有纵向延伸的焊缝的管中。由于第一心轴段的厚度小于管的内部测量值，所以第一心轴段可以插入到管中而不被焊管的向内突出的凸出部分所夹持。在插入第一芯棒段之后，由第三树脂片构成的第二心轴段被迫进入第一和第二树脂片之间的间隔。通过如此迫使第三树脂片材成为间隔，第一树脂片材被垂直地推压以与凸起部分紧密接触。然后将具有如此插入其中的第一，第二和第三树脂片的管弯曲成弯曲。管弯曲后，首先将第三树脂片从弯管拉出。随后将第一和第二树脂片从弯管中拉出。

摘要： A method and means for bending pipe and other hollow bodies into arcuate shape while restraining collapsing tendencies of the walls by supporting the pipe internally on a close-fitting, crush-resistant flexible arbor, and expanding the arbor size by applying pressurized fluid within an annular deformable chamber or within flexible tubing wound helically about the periphery of the arbor. When bending thermo-plastic pipe which previously has been heated to above the deformation temperature in the areas to be deformed, circulating pressurized fluid also serves as a heat exchanger, hastening the cooling process.

摘要： A method for bending a thin-walled tube to form a small radius bend on the thin-walled tube includes providing a die, lubricating the thin-walled tube, extruding the thin-walled tube, and thrusting elastomer fillers. A die defining a curved cavity enclosed within is provided. The curved cavity is configured to receive the thin walled tube. The thin-walled tube is lubricated using an antifriction coating material applied on an exterior surface of the thin-walled tube for reducing friction between the exterior surface of the thin-walled tube and the curved cavity of the die. The thin-walled tube is extruded into a curved section from an insertion end of the die. The elastomer fillers are thrusted into an inner surface of the thin walled tube via a mandrel. The mandrel is forced against the thin-walled tube to prevent damage of the inner surface of the thin-walled tube to form the small radius bend.
