摘要： Systems and methods of forming articles using electromagnetic radiation are disclosed. In some aspects, the system includes a plurality of forming modules movably mounted relative to an infeed mechanism. The infeed mechanism is configured to supply pre-form articles to the plurality of forming modules, and each of the plurality of forming modules includes a multi-segment mold disposed about an electromagnetic coil. The electromagnetic coil is configured to impart an electromagnetic force on the pre-form articles when supplied with electrical energy that urges the pre-form articles into contact with the multi-segment mold to produce the formed containers.

摘要： A hollow preform impact extruded from a metal billet to produce a progressing wall at a transition wall thickness. An axially forward portion of the progressing wall is ironed by extrusion past an extrusion point to form a sidewall portion of a lesser thickness. Extruding is stopped while some of the billet remains to form the closed bottom end. The preform has a bottom portion, a sidewall portion and a transition wall portion extending between the bottom portion and the sidewall portion. The transition wall portion is thicker than the sidewall portion and can be formed into at least part of the rim of an expansion shaped container. An impact extrusion punch has a central axis, an axially forward, impact surface for impacting metal to be extruded, a transition region for directing material displaced by the impact surface and a rear extrusion point for ironing material extruded past the transition region.

摘要： The principles of the present invention further provide both a shaped metal container and its preforms that exhibit a rounded grain structure characteristic created by an annealing process and a method for making a shaped metal container. The process of making said metal container results in a quicker process time and uses less metals (at least 10% metal weight savings), thus allowing for a decrease in the costs of making such shaped metal containers. A shaped metal container may include work hardened rolled sheet-metal defining a sidewall, an opening, and a base, where at least one section along the sidewall has grains with an average aspect ratio less than about 4 to 1.

摘要： A system and method of manufacturing a metal vessel may include providing a preform being formed of work hardened aluminum. The preform may have an open portion, a closed portion, and body portion. A multiple segment mold may be closed around the preform. The multiple segment mold may include at least one projecting portion operative to partially deform the preform while closing the mold. The preform may be blow molded by causing a step-like change in pressure within the preform to cause the preform to take a shape defined by the mold when the mold is in the closed position. The molded preform may be removed from the mold.

摘要： A method of forming a bottle-shaped or other contoured metal container by providing a hollow metal preform having a closed end and a wall thickness that decreases progressively in a direction away from the closed end, and subjecting the preform to internal fluid pressure to cause the preform to expand against the wall of a die cavity defining the desired container shape. The method may be employed in pressure-ram-forming procedures wherein a punch is advanced by means of a backing ram into the die cavity to displace and deform the closed end of the preform.

摘要： In hydroforming of hollow metal articles in a die, such as pressure-ram-forming procedures, a method of decreasing cycle time of the forming process, while ensuring acceptable product properties and avoiding failures, by modeling the process using finite element analysis to establish a pressure-time history that optimizes the forming operation and applies failure limits to selected variables such as minimum wall thickness or maximum strain rate, and transferring this pressure-time history to a computer controlling the forming process. Thermocouple and/or continuity sensors are incorporated into the die wall and connected to the computer so as to provide active feedback from the die to the control of the process.

摘要： An upper die is movable by a ram downwardly against a lower die with the dies enclosing a hollow article such as a knobshell in die cavities thereof. RAM continued downward movement of the closed dies forces a piston connected to the lower die downwardly against hydraulic fluid of a containing cylinder forcing the hydraulic fluid internally of the knobshell through the neck thereof forming the knobshell outwardly against the die cavity surfaces. The piston size compared to the knobshell size automatically creates a reactive force reversely tending to maintain the dies closed greater than the internal knobshell forming force tending to separate the dies. After knobshell forming, reverse ram movement first relieves piston pressure against the hydraulic fluid and ultimately separates the dies with a knockout member being actuated to eject the formed knobshell. During forming, an automatic pressure relief valve maintains maximum hydraulic fluid pressure not exceeding a predetermined maximum pressure and an automatic fluid refill valve refills the cylinder with hydraulic fluid at separation of the dies for formed knobshell removal.

摘要翻译： 上模具可以通过冲头向下移动抵靠下模具，模具在其模腔中包围诸如旋钮的中空制品。 RAM的持续向下运动使密封模具将与下模具连接的活塞向下压靠在容纳圆筒的液压流体上，迫使旋钮壳内部的液压流体通过其颈部向外形成针模腔表面。 与旋钮尺寸相比，活塞尺寸自动产生反作用力，反作用力使得模具闭合大于倾向于分离模具的内部旋钮形成力。 在旋钮形成之后，反向柱塞运动首先将活塞压力抵靠液压流体释放，并且最终将分离模具与正被致动的敲击构件分离以弹出形成的旋钮。 在成形期间，自动减压阀保持最大液压流体压力不超过预定的最大压力，并且自动流体补充阀在分离模具时用液压流体重新填充气缸，用于形成的旋钮拆卸。
