摘要： A hydroforming apparatus includes upper and lower platens that are connected together by tie rods extending through respective compression tubes. An upper die section is carried on the upper platen by a generally C-shaped suspension arm, while a lower die section is carried on the lower platen. The upper and lower die sections have recessed areas formed therein that define a die cavity. Lift assemblies are provided on the lateral ends of the hydroforming apparatus for selectively elevating the lower die section upwardly into engagement with the upper die section. When the lower die section is elevated by the lift assemblies, a workpiece is enclosed within the die cavity. A bolster is then moved between the hydroforming die and the lower platen. A cylinder array containing a plurality of pistons is next hydraulically actuated so as to securely clamp the hydroforming die between the cylinder array and the lower platen. While the cylinder array is actuated, pressurized fluid is supplied within the workpiece, deforming it into conformance with the die cavity.

The platens are connected together by tie rods extending through respective compression tubes. The upper and lower die sections have recessed areas formed therein that define a die cavity. When the lower die section is moved to a lowered position, a workpiece can be disposed in the recessed area formed therein. Then, the lower die section and the workpiece are elevated by cylinders such that the workpiece is enclosed within the die cavity and mechanically deformed by the cooperated upper and lower die sections. A support block is then moved between the hydroforming die and the lower platen. A cylinder array containing a plurality of pistons is next hydraulically actuated so as to securely clamp the hydroforming die between the cylinder array and the lower platen. While the cylinder array is actuated, pressurized fluid is supplied within the workpiece, deforming it into conformance with the die cavity.

摘要： An apparatus and method of applying a lubricating material to an outer surface of a workpiece. Initially, a workpiece is provided that is preferably formed from a closed channel structural member having a circular or box-shaped cross sectional shape. Lubricating material is applied to an outer surface of the workpiece. In a second step of the method, the workpiece may be heat treated. The workpiece is then heated to elevate the temperature of the workpiece so as to cause the lubricating material to dry substantially immediately on the workpiece, thereby providing a coating of lubricating material having a substantially uniform thickness. In a fourth step of the method, a deforming process is performed on the workpiece during the period of time following the heat treatment process, and after applying the lubricating material, in which the workpiece retains the full or partial softening characteristics.

摘要： A method for hydroforming a closed channel structural member that allows the perimeter to be increased, but which maintains a relatively uniform wall thickness throughout, includes the initial step of disposing a closed channel structural member, such as a tube, within a first hydroforming die defining a first die cavity. The inner surface of the first die cavity corresponds in cross sectional shape to the outer surface of the tube, but the perimeter of the first die cavity is somewhat larger than the perimeter of the tube enclosed therein. A preliminary hydroforming operation is then performed at a relatively high pressure to expand the tube into conformance with the first die cavity. Throughout most of this expansion, the outer surface of the tube does not engage the inner surface of the die cavity. As a result, as the perimeter of the tube is increase, the wall thickness thereof is decreased uniformly. The preliminarily expanded tube is then disposed within a second hydroforming die defining a second die cavity. The inner surface of the second die cavity corresponds in cross sectional shape to the desired final shape for the tube. When the second hydroforming die is closed, a final hydroforming operation is performed at a relatively low pressure to deform the tube into conformance with the second die cavity. Because the perimeter of the tube is approximately equal to the perimeter of the second die cavity, the wall thickness of the tube is unchanged by the final hydroforming operation.

摘要： A laser blanking device for high speed cutting of a rapidly fed strip of coil stock is disclosed and includes a support frame extending along a first longitudinal axis and a conveyor supported by the support frame. A strip of coil stock material is fed onto the conveyor at a pinch roll located near a first end of the frame. Transverse, moveable gantries above the conveyor suspend lasers. A pinch roll located near a second end of the frame assists movement of the material. Multiple laser cutting operations are simultaneously performed on the material as it moves along the device, and a laser head suspended from a gantry situated after the second pinch roll completes a cut that separates a blank from the remainder of the stock material.

摘要： A laser blanking device for high speed cutting of a rapidly fed strip of coil stock includes a pin conveyor traveling a recurring loop along a longitudinal axis. At least two moveable gantries are supported above the pin conveyor. Each gantry is capable of moving at least a limited length along the longitudinal axis. At least one moveable laser head is suspended on each gantry, and the laser heads are capable of moving along the corresponding gantry along multiple axes transverse to or parallel to the longitudinal axis of the device. The device further has an entry pinch roll assembly and a second pinch roll assembly positioned at opposed ends of the conveyor. A pair of pinch rollers cooperates with each pinch roll assembly to apply tension to the strip traveling therebetween. Each pinch roller continually feeds the moving strip along the conveyor while the laser heads situated between the pinch roll assemblies move and progressively cut a perimeter portion of a blank or cut-out from the moving strip.

摘要： A method of manufacturing a sleeve mechanism without the use of machines by using a hydroforming process. The method includes the steps of providing an inner sleeve, an intermediate sleeve, and an outer sleeve concentrically within one another. The concentric sleeves are then expanded by using a hydroforming process such that an external thread is formed on the inner sleeve and an internal thread is formed on the outer sleeve. After the hydroforming process, the intermediate sleeve is removed by using any desired manner, such as melting or chemical dissolution. The relatively small space remaining between the inner and outer sleeves allow them to freely rotate about each other to ensure smooth operation of the screw and sleeve mechanism. Alternatively, the inner and outer sleeves may be hydroformed in separate operations.

摘要： A hydroforming apparatus for simultaneously performing two or more hydroforming operations includes a frame that is sized to support a plurality of hydroforming dies in a stacked relationship. Each of the dies includes a pair of cooperating die sections having respective recesses formed therein that define a die cavity. Initially, the first die section of the first die is positioned in an uppermost spaced apart position relative to the second die section of the second die, while the second die section of the first die and the first die section of the second die are positioned in an intermediate spaced apart position relative to both the first die sect of the first die and the second die section of the second die. Then, hollow tubular blanks are inserted between the spaced apart die sections of the first and second die Next, the ram and the support mechanism are moved downwardly relative to the be such that the pairs of cooperating die sections of the first and second dies engage one another. End feed cylinders are then moved laterally into engagement with the end the tubular blanks to facilitate the filling thereof with a hydroforming fluid. The pressure of the fluid within the tubular blanks is then increased to such a magnitude that the tubular blanks are expanded outwardly into conformance with the respective die cavities. Thus, the hydroforming apparatus is capable of performing two or mo hydroforming operations simultaneously to decrease the overall amount of operational cycle time and, therefore, increase overall productivity.
