摘要： A hydroforming system includes a dual conical tube formed from a blank. The dual conical tube has a first end, a second end and a central portion positioned between the first and the second ends. The central portion has a smaller cross sectional area than the first and the second ends. A shaping die is adapted to receive the dual conical tube, and the shaping die is subject to pressurize such that the tube substantially approximates the shape of the shaping die.

摘要： A mold clamping apparatus includes a frame including a holding portion for holding a mold and an open portion allowing the mold to be inserted into/taken out from the holding portion in a direction of the longer side of the mold, a mold moving device for moving the mold to insert/take out the mold into/from the holding portion through the open portion in the frame, and a mold opening/closing device for opening/closing the mold located outside the frame. This mold clamping apparatus is capable of holding the mold securely in a closed state resisting a pressure acting to open the mold and allows reduction of energy consumption, equipment maintenance cost, production cost, and the size thereof.

摘要： A method and an apparatus are provided for internal high-pressure forming of a workpiece in a closed internal high-pressure forming die. The workpiece is expanded owing to the internal high fluid pressure exerted by a pressure generator and coming to rest on the cavity of the forming die. The workpiece and the forming die form friction partners in the areas of contact. In order to improve process reliability during the internal high-pressure forming of workpieces and to expand the scope of the method, vibration is imparted directly to at least one of the friction partners by a vibration generator during forming.

摘要： In the present invention, at least one tubular blank and at least one article such as a metal stamping, to be attached to a hydroformed part, are loaded into a die. The tube is hydroformed using typical methods. The article is positioned in the die such that, when the tube is hydroformed, the final hydroformed tube contacts the article at least at a point. Attachment means, such as a laser welder, are provided with access to the contact point between the article and the hydroformed tube so that a tack weld or other attachment can be made between the article and the hydroformed tube while still in the closed die. The hydroformed tube and attached article are then removed as a joint assembly from the die.

摘要： A frame member of rectangular cross section with rounded corners is formed by expansion of a tubular blank within a die cavity having an inner portion of corresponding cross section and an outer transition portion which is of smoothly continuously curved cross sectional profile elongated substantially parallel to the larger dimension of the rectangular section. An outer portion of the tubular blank is deformed to correspond with the continuously curved cross sectional profile and is sealed by a resiliently compressible sealing element of corresponding profile through which fluid pressure is applied in order to expand the blank. By matching the profile of the transition portion to the rectangular inner portion, the transition portion can be made shorter and considerable savings of materials and resources can be achieved.

摘要： A method and apparatus for hydroforming a metallic tube including the steps of: preliminarily expanding the metallic tube over an axial section longer than the length of the expanded portion of a final product as measured in the axial direction of the metallic tube; and compressing the preliminarily expanded portion in the axial direction of the metallic tube so as to form the shape of the expanded portion of the final product. According to the method and apparatus of the invention, frictional resistance between the metallic tube and processing tools can be reduced, and moreover, the internal pressure within the metallic tube can be reduced during expansion processing. Furthermore, the cost for the manufacture of metallic die is reduced, and in addition, yield is improved
