Patent number: 4676090Abstract: A press machine is disclosed which is provided with a plurality of press dies fixedly secured on a bolster. The machine has a vertically reciprocable frame member with a predetermined constant stroke, which carries a plurality of pressure plates cooperating with the die, respectively. Each pressure plate is axially movable with respect to the frame member and threadedly connected with a spacer plate arranged between the frame member and the pressure plate. The shut height of the machine can be individually adjusted for each pressure plate, by rotating the spacer plate relative to the pressure plate. The shut height can be optimized very easily and in short a time so that the productivity can considerably be improved.Type: GrantFiled: October 29, 1984Date of Patent: June 30, 1987Assignees: Hashimoto Forming Industry Co., Ltd., Kabushiki Kaisha Shibakawa SeisakushoInventors: Tatsuo Nishimura, Tatsuya Tamura

Patent number: 4660451Abstract: The invention relates to a scrap shearer comprising a displaceable frame (1) and a pair of blade units (2, 3) shearing in a scissor-like manner, whereby the blade units are fastened on the frame (1) so that at least one of the blade units (2, 3) is pivotable. The object of the invention is to provide a scrap shearer which is displaceable to such large scrap objects as e.g. ships and which is capable of advancing within the scrap object, by means of which shearer the requirements of different kinds of scrap objects can be taken into account in the best possible way. This is achieved according to the invention in such a manner that fastening means (7, 8, 11) of the pivotable blade unit (2) are adjustable for the adjustment of the shearing gap and/or angle between the blade units (2, 3).Type: GrantFiled: September 19, 1985Date of Patent: April 28, 1987Inventor: Pekka Bjorkheim

Patent number: 4604930Abstract: A light-weight press for punching, forming, etc., in which the guide pins are bored in order that pull rods may be passed therethrough from actuating cylinders to an adjustment mechanism that interrelates the upper ends of the guide pins with the platen of the press. The adjustment mechanism are connected to each other so as to operate simultaneously and ensure that the forces in the press do not become unbalanced. Downward movement of the platen is limited by striking of the upper ends of the guide pins by stop elements associated with the pull rods.Type: GrantFiled: April 30, 1984Date of Patent: August 12, 1986Inventors: Robert M. Avila, Glenn A. Hoffman, Jr.

Patent number: 4499806Abstract: A multiple gob glass shearing mechanism in which the sets of opposed shear blades are supported for movement toward and away from each other in a straight line or with parallel motion. One set of shears is mounted on a shear guide that can be adjusted up or down relative to the holder of the opposed set of shears. This adjustment is for the purpose of adjusting the tension on all the sets of blades simultaneously and can be affected when the shears are in operation. The drive for the shears may be unlatched for safety purposes when out of position and when put back into operation the shear blades will not close unless the latch is refastened.Type: GrantFiled: October 13, 1983Date of Patent: February 19, 1985Assignee: Owens-Illinois, Inc.Inventor: Eustace H.
