摘要: An apparatus and method for moving a wire along its own axis against a high resistance to its motion causing a substantial uniaxial compression stress in the wire without allowing it to buckle. The apparatus consists of a wire gripping and moving drive wheel and guide rollers for transporting the moving wire away from the drive wheel. Wire is pressed into a peripheral groove in a relatively large diameter, rotating drive wheel by a set of small diameter rollers arranged along part of the periphery causing the wire to be gripped by the groove.

摘要: Die arrangement for use with conventional and hydrostatic extrusion presses consisting of a first die for providing a first extruded section of a billet and a second die cooperating with the first die to further extrude said first extruded section to final shape. Successive dies beyond the second die are contemplated to provide successive step-wise extrusion for greater reductions, especially of large billets. The method of the invention comprises step-wise incremental sequential extrusion of the billet and extruded portions of the billet until the final shape is achieved.

摘要: Disclosed herein is a method to produce a semi-crystalline fluoro-polymer film. A semi-crystalline fluoro-polymer material is used. The material is compressed to produce the film. During compression, the material is maintained at a temperature below the melting point of the material. The compression step can be cycled to allow cooling of the material between compression stages. Alternative methods are provided for compressing the material with a co-extrusion substrate, extruding the material and utilizing mandrel expansion for the material.

摘要: A hydrostatic extrusion apparatus whereby thermoplastic polymers can be hydrostatically extruded in a solid state is described. The apparatus includes:(a) an outer casing or tooling support means,(b) a container assembly concentrically contained within the outer casing and having pressure means attached thereto to provide extrusion pressure to a fluid in the assembly, sealing means to prevent leakage of the fluid, means for holding a polymer billet and including a die portion, and(c) a receiver assembly axially aligned with the container assembly concentrically within the outer casing having pressure means to clamp the container and receiver assemblies together, a mandrel for holding and aligning a mandrel-head in spaced relationship with the die, and means for receiving, lubricating and cooling the extrudate.Optionally, means for preheating and loading the polymers into the container assembly are provided whereby the press may be operated on a semi-continuous or continuous basis.

摘要: A resettable apparatus including a deformable restraining element adapted to contact and restrain active elements for producing a time-delayed force or displacement response. The apparatus functions by the release of the force and/or displacement active element by the creep deformation action of the restraining element at a time interval after actuation of the active element.
