Barrel Form and Manufacturing Process for Same

Номер: US20120000565A1
Автор: Bryan Scheuhing, Ken Bolam, M. Shane Price
Принадлежит: Goody Products Inc

A process of making an adjustable diameter barrel form includes the steps of providing a sheet formed of metal and folding the sheet along a widthwise bend. Pressure is applied to the sheet along the bend within a rolling device. The sheet is rolled within the rolling device over its length gradually moving the bend from one lengthwise end to the other lengthwise end while applying the pressure. The pressure is removed to release the sheet so that the sheet can roll up in a lengthwise direction into a coil. The rolling device can include a pair of rollers, an arbor, and a mandrel on the arbor. The rolling device can include a base plate, a press plate, and a mandrel between the plates.

Device And Method For Explosive Forming

Номер: US20120024029A1
Автор: Alexander Zak, Andreas Stranz, Franz Trubert
Принадлежит: COSMA ENGINEERING EUROPE AG

A device for explosive forming of a tubular work piece includes a multipart explosive forming die, which defines a forming area having an inner surface corresponding to a final shape of the tubular work piece and a nozzle arrangement disposed adjacent to the forming area. The device also includes a plug for forming a seal by simultaneously deforming an end of the work piece and clamping the deformed end between the plug and a facing surface of the nozzle arrangement. In this way, the work piece itself contributes to the sealing of an internal explosion space. With insertion of new work piece blanks, and introduction of the plug during each individual forming process, new seals are produced in a convenient manner during subsequent forming processes. The device supports a simplified handling approach and integrates several functions into one working step, resulting in a shorter cycle times and cost-effective industrial production.

A component of a vehicle structure is obtained by a hot forming operation on a hybrid panel having a sheet element of light alloy and a sheet of plastic material. The hybrid panel is hot formed by pressing it against a forming surface of a mould element by a pressurized gas or by a second mould element. Following this operation, the hybrid panel assumes a configuration corresponding to the forming surface, whereas the light alloy sheet element and the plastic material sheet constituting the hybrid panel adhere to each other following softening by heat of the plastic material. Before the hot forming step, a surface of said light alloy sheet element which must contact the plastic material sheet is subjected to a roughening treatment, thereby defining surface asperities between which the plastic material of the plastic material sheet is inserted when it is softened by heat. 1. A method for obtaining a component of a motor-vehicle structure by a hot pressing operation on at least one sheet element of light alloy , said method comprising the steps of:providing a hybrid panel adjacent to a mould element having a forming surface,wherein said hybrid panel comprises at least one sheet of plastic material in contact with said at least one sheet element of light alloy substantially along an entire extension thereof, so that said hybrid panel has at least one layer of light alloy sheet and one layer of plastic material,hot forming said hybrid panel in its entirety by pressing it against said forming surface of said mould element with a predetermined controlled pressure and by simultaneously applying heat, until the hybrid panel assumes a configuration corresponding to that of said forming surface,wherein preliminarily to the hot forming step of the hybrid panel, a surface of said at least one sheet element of light alloy which is to come in contact with the at least one sheet of plastic material is subjected to a roughening treatment, so as to define surface asperities,wherein ...

Rather than using a conventional stamping forming process with steels having high ultimate tensile strength and relatively low initial yield, tubular hydroforming techniques are introduced to synergize with BIW part forming, or forming of other load bearing parts. Such steels can have ultimate tensile strengths of greater than 1000 MPa and initial yields of less than 360 MPa In some embodiments, the steels have elongation of at least 40%. Such steels can include retained austenite. 1. A process for forming steels with high ultimate tensile strength and low initial yields comprising the steps of:a. Forming an initial tube blank by selecting a raw tube diameter sufficient to permit stretching of the steel in a later hydroforming step to reach a pre-determined yield strength while keeping induced material thinning within pre-determined failure limits and pre-determined design tolerance and forming an initial tube blank conforming to said diameter;b. Pre-bending said initial tube blank to generate a smooth curvature in a bent tube;c. Hydroforming the bent tube in a mold by filling the bent tube with a pressurized liquid until walls of the bent tube contact the mold to form a part;d. Trimming the formed part.2. The process of wherein the steel contains retained austenite.3. The process of wherein before hydroforming the steel has an ultimate tensile strength of greater than 1000 MPa and an initial yield strength of less than 360 MPa.4. The process of wherein before hydroforming the steel has an ultimate tensile strength of greater than 1150 MPa.5. The process of wherein the tube blank is subject to at least one of preforming or intermediate hydroforming after pre-bending and before hydroforming. This application claims priority to U.S. Provisional Application Ser.

Provided is a method for quick forming of a hot metal sheet. The method relates to a technology for forming a metal sheet part, and solves the problem that the existing hot metal sheet forming technology cannot ensure that a blank is deformed under reasonable temperature and pressure conditions, thereby failing to realize precise and quick forming of a complex metal sheet part, especially a thin-walled part. The method mainly includes the following steps: step one, placing a metal sheet blank to be formed on a forming mold; step two, introducing high-pressure gases with equal pressures simultaneously into upper and lower enclosed cavities respectively formed by the metal sheet blank and the sealing mold, and the metal sheet blank and the forming mold; step three, heating the metal sheet blank to a preset forming temperature condition; step four, quickly releasing the high-pressure gas from the cavity formed by the metal sheet blank and the forming mold, such that the metal sheet blank bulges; and step five, discharging the gas from the cavity formed by the metal sheet blank and the sealing mold, and opening the mold to obtain a formed metal sheet part. The present invention is used for manufacturing a metal sheet part. 1. A method for quick gas bulging forming of a hot metal sheet , wherein the method is implemented according to the following steps:step one, placing a metal sheet blank to be formed on a forming mold, and closing a sealing mold to form enclosed cavities on upper and lower surfaces of the metal sheet blank;step two, introducing high-pressure gases with equal pressures simultaneously into upper and lower enclosed cavities respectively formed by the metal sheet blank and the sealing mold, and the metal sheet blank and the forming mold;step three, heating the metal sheet blank to a preset forming temperature condition;step four, quickly releasing the high-pressure gas from the enclosed cavity formed by the metal sheet blank and the forming mold, such ...
