摘要： Disclosed is a cartridge case for various caliber ammunition that consists essentially of a powdered metal and/or powdered metal alloy that is formed into the cartridge case through an injection mold processing. Also disclosed is a method for forming a cartridge case, which may include use of Metal Injection Molding (“MIM”) processes to produce the cartridge case which retains a primer, propellant, and/or a bullet. The method can include metal injection molding an initial part, and also at least one of tapering and trimming the initial part to form the finished cartridge case. Further embodiments can include the use of Finite Element Method (FEM) analysis to develop an optimized MIM design.

摘要： A transport puck vertically aligns a caulking cartridge, nozzle-down. The puck includes (i) a substantially solid lower plug portion, having a lead face and a bottom face and an center passageway that is at least partially inverted frustum-shaped that forms a side contact face that tapers from a wider lead face opening to a narrower bottom face opening; and or to a tubular sleeve from the side contact face to the bottom face opening; (ii) an upper sleeve, shaped to receive the caulking cartridge in a desired vertical alignment to the lower plug portion; and (iii) at least one funnel-shaped bore into the bottom face with an inserted connector comprising a head and stem, the head spaced within the bore to define a spacing that has been determined to identify bottom face wear.

摘要： High strength, high precision thin-walled cartridge cases are manufactured from a metal of interest selected from low alloy and carbon steels utilizing an extrusion and heat treating process. The cartridge blanks are extruded to a length greater than that necessary for the finished cartridge case and are provided with one or more peripheral grooves close to the open end of the extruded cartridge blank to prevent warpage during subsequent heat treatment.

摘要： A method is taught of manufacturing cartridge cases having a substantially cylindrical outer side wall surface and a tapered inner side wall surface. The method comprises the steps of initially forming a cup-shaped article having substantially cylindrical inner and outer side wall surfaces, a substantially flat outer bottom surface with an annular chamfered surface joining the flat outer bottom surface to the outer side wall and an inner bottom wall surface. Thereafter, the cup-shaped article is engaged by a punch element and the punch element forces the cup-shaped article through a series of die members without any intermediate annealing of the article after passage through any of the die members. The punch element has an outer side wall and a bottom wall, the bottom wall being dimensioned so that the diameter of the peripheral edge of the bottom wall is substantially the same as the diameter of the peripheral edge of the inner bottom wall surface of said cup-shaped article whereby at least the peripheral edge of the bottom wall of the punch element will contact the peripheral edge of the inner bottom wall surface of the cup-shaped article when the punch element engages the cup-shaped article to thereby align the punch element and the cup-shaped article with one another for forcing the cup-shaped article through the series of die members. The side wall of the punch element is tapered so as to correspond in configuration and dimension to the configuration and dimension of the tapered side wall surface of the cartridge case to be formed. The die members, the cup-shaped article, and the punch element are dimensioned so that the cup-shaped article is only subjected to ironing during passage through the die members to thereby increase the length of the side wall of the cup-shaped article while reducing the thickness of the side wall thereof.
摘要翻译：制造具有基本上圆柱形的外侧壁表面和锥形内侧壁表面的制造盒壳体的方法。该方法包括以下步骤：最初形成具有基本上圆柱形的内侧和外侧壁表面的杯形制品，基本上平坦的外底表面，其具有将平坦的外底表面连接到外侧壁的环形倒角表面，以及内底壁表面。此后，杯形制品由冲头元件接合，并且冲压元件迫使杯形制品穿过一系列模具构件，而在通过任何模具构件之后，制品没有任何中间退火。冲头元件具有外侧壁和底壁，底壁的尺寸使得底壁的周边边缘的直径与所述杯的内底壁表面的周边边缘的直径基本相同其中当冲头元件接合杯形制品时，至少冲头元件的底壁的周边边缘将接触杯状物品的内底壁表面的周边边缘，从而使冲压元件和杯形制品彼此用于迫使杯形制品穿过一系列模具构件。打孔元件的侧壁是锥形的，以便在待形成的盒壳体的锥形侧壁表面的构造和尺寸上对应于构造和尺寸。模具构件，杯形制品和冲头元件的尺寸被设计成使得杯形制品在通过模具构件期间仅经受熨烫，从而增加杯形制品的侧壁的长度，同时减小其侧壁的厚度。

摘要： Apparatus and a method of employment thereof for forging cylindrical shells of controlled interdimension wherein a single punch die mandrel and cushion cooperate at a single work station to subject a metal blank to high multi-axial stress sufficient to increase the ductility thereof and permit a completed article to be fabricated during a single continuous pass of the material through the die. Precise control of the interdimension of the desired part is maintained by means precisely shaping the material and maintaining engagement between the end face of the mandrel and the bottom of the work blank during the forging process.
