| 87 | Method for manufacturing an edge protector and die assemblies therefor | US12155215 | 2008-05-30 | US07650773B2 | 2010-01-26 | Fumihiko Shikano; Keizo Matsumoto; Tsugio Saito |
| In primary press forming process, a piece of blank sheet metal is draw worked so as to form a preformed work piece (Wb) provided with a bent portion (a) substantially conforming to a three dimensional contour of a leading edge of a blade to be protected and extending along a longitudinal direction, and a pair of planar portions (b and c) extending from either side of the bent portion. In a secondary press forming process, the planar portions (b and c) of the preformed work piece are stretch formed into a final shape that conforms to the corresponding profile of the blade while the bent portion (a) of the preformed work piece is clamped and protected from deformation. In other words, the bent portion of an edge protector (100) is already given with the final shape of the edge protector by the primary press forming process while the planar portions (b and c) thereof are given with the final shape by the secondary press forming process so that the two press forming processes can be executed without interfering with each other, and only two relatively simple press forming processes are required for forming the complex three dimensional shape of the edge protector. | ||||||

| In a forming press, a blank is pressed formed into a press-formed workpiece by means of an upper die and a lower die, while a peripheral edge portion of the blank is clamped by means of a die and a blank holder insert of the forming press. Subsequently, a central portion of the press-formed workpiece is partially held by means of the upper die and the lower die so as to draw a peripheral portion of the press-formed workpiece away from the central portion thereof, thereby removing strain from the press-formed workpiece. | ||||||
| 89 | Stretch-forming machine with servo-controlled curving jaws | US177184 | 1998-10-22 | US6018970A | 2000-02-01 | Jesse Carl Ford; Larry Alexander Polen |
| A stretch-forming machine of the type wherein a pair of opposed curving jaws grips opposing ends of a metal sheet to be stretch-formed in a curved configuration. Each of the jaws are formed of an array of adjacent grippers movable relative to each other by respective hydraulic cylinders to define a part of the curve of the jaw. The improvement to the stretch-forming machine which is the subject of this application comprises a closed-loop servo-control means for moving each one of the grippers into a predetermined position relative to each other. Each of the servo-control means comprises a hydraulic cylinder position controller carried by the hydraulic cylinder of the one gripper for controlling hydraulic fluid flow to the hydraulic cylinder responsive to stored data representing the desired predetermined position of one of the grippers. A motor is provided for actuating the position controller in response to the data received by the position controller to move the hydraulic cylinder. Hydraulic cylinder position feedback means is positioned on the hydraulic cylinder for sensing the position of the hydraulic cylinder and communicating a signal representing the position of the hydraulic cylinder to the position controller. | ||||||

| 91 | Machine and process for leveling sheet metal strip | US798815 | 1985-11-18 | US4751838A | 1988-06-21 | Kenneth Voges |
| A machine for leveling sheet metal strip without severing or marring the strip includes two stretcher frames, each having a set of jaws which clamp down on the strip, so that a segment of the strip is isolated between the jaws of the two frames. While the jaws grip the strip with enough compressive force to prevent the strip from slipping in the jaws, and yet not mark it, the frames are forced apart with enough force to stretch the isolated segment beyond its elastic limit for the entire width of the isolated segment, thus leveling the segment. Thereupon the parting force is released, and after the isolated segment has recovered its elastic deformation, the jaws release the strip, and the strip is advanced a distance not exceeding the length of the previously isolated segment. The procedure is then repeated until the entire strip has been leveled. The machine may be utilized in combination with a feeding machine which grips the leveled portion of the strip and advances it a preset distance. | ||||||
| 92 | Method and means for processing metal sheets | US957656 | 1978-11-03 | US4211102A | 1980-07-08 | Arnold Hurvitz |
| Method of processing metal sheets which includes the steps of applying tensile stress to an intermediate region of a sheet of metal by engaging the sheet on opposite sides of the region, deforming the intermediate region of the sheet and removing the tensile stress applied to the sheet. The intermediate region of the sheet may be deformed by embossing and the tensile stress can be applied to the intermediate region of the sheet by forming a bead on opposite sides of the region. The means for processing metal sheets comprises first means including die members for forming beads on opposite sides of a metal sheet, and second means for deforming the intermediate region of the sheet while the stress is applied thereto by the first means. | ||||||
| 93 | Method and apparatus for producing long flat metal strip from a coiled metal strip with uniform straight edges to a high degree of precision | US3795127D | 1972-06-19 | US3795127A | 1974-03-05 | DEMUS A |
| A method and apparatus for producing long flat metal strip from a coiled metal strip so that the flat metal strip has uniform straight edges to a high degree of precision. The uncoiled strip is straightened by traction to a degree slightly beyond its elastic limit, laid flat unclamped on a bench, then immobilized on the bench and the edges trimmed by mobile shears movable on a longitudinal guide member lying parallel to the axis of the bench and the metal strip thereon.

| 94 | Stretcher for stretch forming sheet and plate stock | US3595057D | 1969-04-15 | US3595057A | 1971-07-27 | MACKENZIE ROBERT A |
| The stretcher comprises a frame with two stretch units mounted thereon for adjustment toward and away from each other for accommodating therebetween selected lengths of sheet or plate stock to be stretched or stretch formed. A male die is supported between the units when stretch forming is to be effected. Each unit comprises a linkage rockable by power means about a horizontal pivot extending transversely of the stock and tensioning dimension, and carries a stock gripping head. Rocking of the linkages causes the heads to swing about their pivots in directions away from each other for stretching the stock and toward the frame for laying the stock onto the die. The stretcher is characterized in that the horizontal pivot is adjustable along a path extending generally upwardly and downwardly normal to the plane of the stock, and the units can be latched securely in adjusted positions along the frame. With these adjustments, a preselected exact amount of total stretch can be imparted to the stock.
