Manufacture of Lattice Truss Structures from Monolithic Materials

Methods and systems to manufacture lattice-based sandwich structures from monolithic material eliminate the bonding process which is conventionally used to join lattice-based truss cores to facesheets to form sandwich structures. The bonded interface is a key mode of failure for sandwich structures which are subjected to shear or bending loads because the nodes transfer forces from the facesheets to the core members while the topology for a given core relative density dictates the load carrying capacity (assuming adequate node-bond strength exists). In one aspect, a core and related structures provide very low density, good crush resistance and high in-plane shear resistance. Another aspect of the truss structures may include sandwich panel cores and lattice truss topology that may be designed to efficiently support panel bending loads while maintaining an open topology that facilitates multifunctional applications.

The operating temperature of the Induction Heated Extrusion Melter is in excess of two thousand degrees Fahrenheit. Therefore, it can melt many types thermoplastics and metals. The Induction Heated Extrusion Melter could melt metals such as, but not limited to, aluminum, brass or lead and plastics of various shapes and sizes. It could be used in additive manufacturing machines, where shapes are made by adding layers of molten material. It could also be used as part of an extrusion apparatus that extrude long continuous shapes. 1. The Induction Heated Extrusion Melter is an invention that is used to extrude melted plastics or metals. It uses an external regulated electric current to induce an electromagnetic field in a conductive coil to inductively heat a ferrous metal chamber that is partially encased in insulation. The temperature of the chamber has the potential to reach in excess of two thousand degrees Fahrenheit. Which is hot enough melt all know plastics and some metals. Plastic or metal is fed into one end and is melted in the heated ferrous metal chamber. The feeding action from the incoming plastic or metal will force the melted plastic or metal to extrude out the opposite end. Additive Manufacturing Three Dimensional (3D) printers has become a popular technology to bring ideas into reality in a rapid manner. The 3D printer produces shapes by extruding melted plastic in a continuous layer and applying those layers on top of the other. A limitation of 3D printers is that can only extrude plastic, thus it can only produce plastic shapes. The maximum extruder temperature is around six hundred degrees Fahrenheit. This limitation is the main motivation for the development a higher temperature extruder that can melt both plastic and metal. Induction Heated Extrusion Melter was development to ...

Thixo-extrusing apparatus

PURPOSE: A thixo extruding device is provided to prevent temperature difference from occurring and to enable extrusion molding to be performed even at low extrusion pressure since a temperature maintaining unit is formed on a container, a stem and a die. CONSTITUTION: A thixo extruding device consists of a container(10), a stem(30), a die(20) and a cooling unit(40). The container comprises a temperature measuring unit(11) and a first temperature maintaining unit(12). The temperature measuring unit measures the temperature of each part of billet, which is an extrusion material. The stem pressurizes the billet in the container in an extruding direction. The stem comprises a second temperature maintaining unit(31). The die comprises a third temperature maintaining unit(21). The third temperature maintaining unit heats so that the extruded part of the billet is maintained at the same temperature. The cooling unit cools an extruded material, which has been extruded from the die, outside the die.

INSTALLATION FOR PRESS SPINNING, IN PARTICULAR OF ALUMINUM BILLETS

Axial alignment apparatus and method for maintaining concentricity between a slotted tubular and a seamer head

An apparatus for keeping a slotted tubular liner in axial alignment with a seamer head through which it is passing adjusts the spatial position of the seamer head in response to inputs from liner centerline sensors. The seamer head is mounted on a seamer head carrier that is vertically movable relative to a seamer head frame, which in turn is horizontally movable relative to a base structure. A programmable logic controller is programmed to continually poll the liner centerline sensors to determine the position of the seamer head relative to the liner, and to instruct vertical and horizontal axis positioners to move the seamer head as necessary to make the seamer head's rotational axis substantially coincident with the centerline of the liner as the liner passes through the seamer head.
