Patent number: 4506433Abstract: The bending and shearing machine according to the invention comprises a framework, a table which can be vertically displaced and on which sheet metal, such as steel sheets, may slide as well as a rocker head which can be pivoted 180.degree.. The displacement of the table is carried out by means of a system including levers and pistons. One of the horizontal edges of the rocker head carries a knife while the other holds a wedge or a bending roller. The table includes a cutting matrix which carries a knife mounted at the end of the table and a bending matrix shaped to rest on the cutting matrix. The rocker head pivots according to an eccentric axis so that its knife and its wedge or bending roller are offset with respect to one another when they are in operation.Type: GrantFiled: June 10, 1983Date of Patent: March 26, 1985Inventor: Roger Gingras

Patent number: 4457160Abstract: In an automatic punching and bending machine the interspace between the bending device and the punching device is adjustable in order to make the interspace as small as possible and to adjust that interspace in dependence on the length of the working piece of a band material, thereby gaining the advantages that series of different work pieces of high precision can be produced in the same machine. The bending device is removable and can easily be replaced by another one which has been reset in a preceding working process. Therefore standstill periods of the machine are reduced.Type: GrantFiled: January 27, 1982Date of Patent: July 3, 1984Inventor: Adolf Wunsch

Patent number: 4404835Abstract: A tool for being hammered against a piece of sheet metal or the like to form a pair of locking tabs in the sheet metal. The tool includes a body member having an anvil portion at one end for being struck with a hammer, and includes a pair of finger members attached to the other end of the body member for causing the piece of sheet metal to be bent into locking tabs when the anvil portion is struck with a hammer.Type: GrantFiled: September 21, 1981Date of Patent: September 20, 1983Inventor: Marvin E. Frith

Patent number: 4392263Abstract: This rescue tool includes a body, providing a cylinder and a piston extending outwardly of the cylinder, and a pair of jaw members pivotally connected to the body by link members and the piston. The jaw members include cooperating outer prying portions, inner cutting portions and intermediate shearing portions. The cutting and shearing portions include arcuate edges defining overlapping points and the prying portions are thickened to facilitate wedge action. The tool can be powered by a bi-directional motor, reservoir and battery system or can be powered directly from a wrecker motor vehicle system.Type: GrantFiled: February 2, 1981Date of Patent: July 12, 1983Inventor: Michael J. Amoroso

Patent number: 4391123Abstract: The punching machine of this invention comprises a punching head provided with a plurality of punch/die pairs for effecting punching operations of a metal sheet. In the punching head there are defined a plurality of operative positions in each of which there is positioned and actuated a punch/die pair of the said plurality of punch/die pairs. Each punch/die pair is operated independently from the others. The punching machine further includes a numerically controlled programmable manipulator equipped with pincers for gripping a metal sheet and displacing it between the punchs and dies of said plurality of punch/die pairs.Type: GrantFiled: August 15, 1980Date of Patent: July 5, 1983Assignee: Salvagnini Transferica S.p.A.Inventor: Guido Salvagnini

Patent number: 4341264Abstract: A wellhead shearing apparatus suitable for use on oil and gas wells having hydrogen sulfide. The apparatus includes a body with a vertical bore and opposed guideways extending from the bore. A ram assembly with two rams, means for moving each ram in the guideways together with the bore for shearing pipe in the bore and apart for other well operations. One ram has an upper cutting blade and the other ram has a lower cutting blade, which has a hard metal insert providing its cutting edge and the upper cutting blade has a hard cutting edge. The rams are of steel having a maximum hardness of 24 to 26 Rockwell C and the insert has substantially greater hardness. The hard cutting edges of both blades are isolated from the sour gas when the blades are under stress as a result of sealing across the vertical bore.Type: GrantFiled: October 15, 1980Date of Patent: July 27, 1982Assignee: Cameron Iron Works, Inc.Inventors: Fern H. Cox, Irwin Rosenhauch
