20110277595 | Bunter Technology - The invention provides methods for making bunters used to form headstamp indicia into ammunition cases. The invention also provides bunter blanks that are specially configured to yield high quality bunters. | 11-17-2011 |
20110290078 | Methods Of Fabricating A Honeycomb Extrusion Die From A Die Body - A method for screening abrasive wheels for fabricating a honeycomb extrusion die from a die body, and methods for fabricating a honeycomb extrusion die using an abrasive wheel assembly. One method for fabricating a honeycomb extrusion die includes measuring at least one of runout and thickness of each of a plurality of abrasive blades while rotating the blades, selecting a subset of the plurality of blades that have a measured runout or a measured thickness within a predetermined range, and mounting the subset of blades spaced from one another and concentrically aligned along a rotation axis of the abrasive wheel assembly. | 12-01-2011 |
20140060253 | METHODS OF MANUFACTURING A DIE BODY - A method of making a die body configured to extrude a honeycomb body, the method comprising the step (I) of manufacturing a die body and the step (II) of predetermining an upstream slot width W1 of the die body such that the upstream slot width W1 is optimized while a root of each die pin includes a section modulus within a predetermined section modulus range. The method still further comprises the step (III) of predetermining a slot length L such that a pin stress is within a predetermined pin stress range. | 03-06-2014 |
20140076107 | TWO-PIECE GUIDE PIN AND METHOD - A two-piece guide pin for metal forming dies includes a guide pin body formed from a cut length of an elongate, solid bar of stock having a cylindrical shape and a hard and smooth finished exterior surface with an outside diameter selected for close reception and reciprocal motion in an associated die bore. An alignment member is formed on a first end of the guide pin body. A guide pin head is formed from a cut length of an elongate, solid bar of stock having an outside diameter that is substantially greater than that of the guide pin body, and is rigidly connected with the second end of the guide pin body in a generally concentric relationship to define an enlarged head that positively limits travel between an associated die shoe and die pad. | 03-20-2014 |
20160196361 | METHOD OF FORMING HEMMING TOOL | 07-07-2016 |
076107400 | Drawing die | 1 |
20140102258 | Methods for Extrusion Die Housing and Insert - A method for manufacturing an extrusion die is presented. A die housing having an exterior surface and an inner interface surface is formed. A die insert having an outer interface surface and an extrusion surface is formed. The die housing is configured to removably receive the die insert so that the outer interface surface is adjacent to the inner interface surface. The inner interface surface is configured to substantially enclose the outer interface surface. | 04-17-2014 |
076107800 | Steel rule die | 1 |
20090013830 | Roll Formed Flexible Die Plate For Rotary Cutting Tool - A method of making a rotary cutting tool for cutting a web of material comprises the steps of roll forming a first flexible die plate into a cylindrical shape, mounting the cylindrically shaped die plate onto a cylindrically shaped fixture, and machining cutting elements onto the roll formed die plate. The roll formed die plate may then be removed from the fixture and attached to a cylinder. The first die plate can cooperate with a second die plate attached to a second cylinder to cut the thin web of material. | 01-15-2009 |
