摘要： High pressure presses, components for high pressure presses and related methods are provided herein. In one embodiment of the invention, a press base may include a piston cavity formed in the press base and a piston cavity sleeve positioned in the piston cavity. The piston cavity sleeve may include a wall having an outer surface and an inner surface opposite the outer surface. The piston cavity sleeve may further include a floor having an upper surface and a lower surface opposite the upper surface. An outer radius may be formed at a juncture of the outer surface of the wall and lower surface of the floor and an inner radius may be formed at a juncture of the inner surface of the wall and upper surface of the floor. The inner radius may exhibit a radius of curvature that is greater than a radius of curvature of the outer radius.

摘要： Remanufacturing a used cylinder liner includes receiving a used cylinder liner having a fillet relieved of residual compressive stress via service in an engine, and compressing a material substrate of the cylinder liner forming a fatigue sensitive fillet, such that a non-uniform profile of the fillet is reshaped via plastic deformation of the material substrate. Residual compressive stress is restored to the fillet at least in part via the plastic deformation. A mask and used cylinder liner assembly for processing the used cylinder liner during remanufacturing is also disclosed.

摘要： A method of remanufacturing a piston includes machining an exterior surface of a body of the piston to define a reference surface. The reference surface is inwardly offset relative to a portion of the exterior surface adjacent the reference surface. The body is made from a body material comprising a metal. A layer of a cold spray powder is applied to the reference surface via cold spraying to define a piston blank surface. The piston blank surface is outwardly offset relative to the portion of the exterior surface adjacent the reference surface. The cold spray powder is made from a powder material comprising the metal. The piston blank surface is machined to define a piston finish surface. The piston finish surface has a dimension which is within a predetermined range.

摘要： A compression tool suited for aiding the installation of gas cylinders, especially for the underside of fold-and-roll tables. The tool comprises a generally C-shaped clamp subassembly having a lower jaw, an upper jaw, and an arm. A spindle is connected through the upper jaw, the spindle having a spindle lower end. An upper channel member, preferably U-shaped, is connected to the spindle lower end, the upper channel member configured to travel axially along the spindle and engage a first eyelet of a gas cylinder. A lower channel member, also preferably U-shaped, is connected to an outer end of the lower jaw in alignment with the upper channel member, the lower channel member configured to engage an opposing, second eyelet of the gas cylinder, wherein the gas cylinder is compressed and secured within the clamp subassembly and immobilized for installation.

摘要： A method for manufacturing an engine block includes removing material from the top deck of the engine block surrounding a first opening to create a first recessed area, placing a first seal within the first recessed area, positioning a first insert within the first recessed area and against the first seal. The method may also include removing material from the top deck of the engine block surrounding a second opening to create a second recessed area that at least partially overlaps the first recessed area, placing a second seal in the second recessed area and positioning a second insert within the second recessed area and against the second seal.

摘要： A method for repairing the cylinder block of an internal combustion engine. The cylinder block engages a standard cylinder head and includes an outer cylinder casting that surrounds an inner cylinder sleeve. The casting has corrosion formed in an end surface that faces the cylinder head. The method includes the steps of providing a repair ring that is separate and distinct from the cylinder sleeve and has a selected thickness. A counterbore is formed in the end surface of the cylinder casting to remove the corrosion therefrom. The counterbore has a depth that is no greater than the thickness of the ring. The ring is installed annularly about and in close tolerance fit with the cylinder sleeve and is introduced into the counterbore. At least one of the cylinder sleeve and the ring are machined for form thereon respective, generally co-planar surfaces that face the cylinder head.
