Publication number: 20020014102Abstract: A rivet setting machine is provided that includes a movable die supporting member that operates to increase working space when inserting and removing workpieces during non-fastening operations. In a first position, the die supporting member positions a die in an opposed relationship to a punch. In a second position, the die supporting member positions the die at a position apart from the punch, which increases the distance between the die and the punch during non-fastening operations.Type: ApplicationFiled: June 7, 2001Publication date: February 7, 2002Inventors: Yoshiteru Kondo, Yoshiaki Suzuki

Patent number: 6267050Abstract: An hydraulic piston-cylinder assembly configured within a press machine enables adjustments to be made to the shutheight parameter through changes in the positioning of the bed in accordance with hydraulic pressure variations in the piston-cylinder assembly. The cylinder device, which is arranged to be reversibly movable with respect to the piston device under the influence of the pressure variations, is coupled to the bed such that movements of the cylinder device induce a corresponding displacement of the bed, thereby changing the shutheight. The piston device is characterized by a property of tensile elasticity in at least one dimension thereof substantially coincident with the shutheight dimension. Accordingly, in one operating mode, there may be effectuated a reversible displacement of the cylinder device beyond its established range-of-motion by changing the hydraulic pressurization of the piston-cylinder assembly in a manner sufficient to induce an elastic tensile effect in the piston device.Type: GrantFiled: November 25, 1998Date of Patent: July 31, 2001Assignee: The Minster Machine CompanyInventor: Craig Brewer

Patent number: 6182492Abstract: A hemming machine of the type having a base, a nest for supporting a sheet metal part to be hemmed, and at least one die is disclosed in which the nest supporting the part to be hemmed is vertically displaced against the dies in order to form the hem. The improvement includes at least three elongated and external shafts wherein each shaft has one end rotatably mounted to the base so that the shafts are spaced apart and parallel with each other. A nut threadably engages each shaft, and these nuts are swivelly secured to the nest which permits a small amount of angular and radial deflection of the nut and shafts during movement of the nest from its lower to its upper position.Type: GrantFiled: November 1, 1999Date of Patent: February 6, 2001Assignee: E.R. ST. Denis Inc.Inventors: Louis Raffin, Dominique R. M. Baulier

Patent number: 6055904Abstract: A thermoforming press in which the shut height of upper and lower platens is adjustable by a keyed connection between a press frame top assembly and each of four posts of the frame established by pieces which are movable and which also act as cams to raise or lower the frame top assembly, moving the upper platen therewith to vary the shut height. The movable pieces are moved in unison by a drive motor to insure uniform movement of the frame top assembly. The platens are driven by rotary crank plates, which are in turn driven by rotary output shafts of right angle drives. Pairs of rollers engage the perimeter of each crank plate on one side to resist bending loads on each shaft.Type: GrantFiled: December 28, 1998Date of Patent: May 2, 2000Assignee: Brown Machine, LLCInventors: Victor L. Chun, Albert W. Arends

Patent number: 6000271Abstract: A metal forming apparatus utilizes the combination of a wedge shaped die half and a complementary shaped cavity in a frame to shape metal blanks. The cavity includes a metal forming mechanism located adjacent a surface adapted to receive a blank to be shaped. The die half is moveable between an inoperative position outside the cavity and an operative position within the cavity. With the die half in the cavity, the metal forming mechanism can apply the necessary force to shape the metal blank in accordance with the die shape. Forming can be attained through the use of pressurized fluid applied against the blank, mechanical or hydraulic ram forces or the like. After shaping is finished, the die half is withdrawn from the cavity, the die half carrying with it the shaped metal part for part recovery and initiation of another forming cycle.Type: GrantFiled: January 11, 1999Date of Patent: December 14, 1999Assignee: Ap Parts International, Inc.Inventors: Conny Olsson, Bertil Ovg.ang.rd, Lars Eriksson
