    Abstract: A method for forging/molding a coarse blank of an oil cylinder, including steps of: placing burn-in softened aluminum material into a preheated mold; using a first punch head to first forge the aluminum material in the mold cavity from outer side of the molding hole so as to form a blank body of the oil cylinder with a first end cap, a second end cap and a shorter cylinder body; moving out the first punch head and connecting an extension mold with the mold; and immediately using a second punch head to secondarily forge the blank body in the mold cavity from outer side of the extension hole and making the end section of the second punch head extend into the mold cavity to a position near the inner end of the mold cavity, whereby the cylinder body of the blank body outward axially extends to the extension mold into a predetermined length so as to form the oil cylinder.

    Abstract: A method for making a valve assembly is disclosed. The method includes providing a first work piece having a longitudinal axis and a first end and providing a second work piece having a surface. The method also includes disposing the first work piece and the second work piece axially between a pair of aligned elements that are relatively movable toward and away from each other along the longitudinal axis of the first work piece. Additionally, the method includes relatively moving the pair of aligned elements toward each other to axially clamp the first work piece and the second work piece and actuating the pair of aligned elements and delivering to the first work piece and the second work piece a controlled clamping force that acts to coin a zone of surface contact between the first end and the surface. Further, the method includes repeating the actuating of the pair of elements a plurality of times. An apparatus used to perform the method is also disclosed.

    Abstract: A fabrication method for an improved structure practical forged one-piece flange-type ball valve that consists of the forging the initial two blanks of the water inlet seat and the ball valve seat for a one-piece flange-type ball valve, based on the blueprints of conventional one-piece flange-type ball valves, with the water inlet seat having a left pipeline connection section already formed inside and the ball valve seat having a ball valve chamber, its contiguous water outlet port, and a right pipeline connection section already formed inside. To facilitate easier finishing, a shallower mating section is formed at the front end of the water inlet seat for contact with the ball valve chamber of the ball valve seat. A left water-tight gasket containment recess is then lathed in the mating section end surface of the water inlet seat and external threads are died along the outer sides of the mating section. Furthermore, internal threads are tapped in the connection hole at the front end of the ball valve chamber of the ball valve seat to enable the screw fastening of the external threads of the water inlet seat into the connection hole. A right water-tight casket containment recess is formed at the adjoining end surfaces between the water outlet port and the ball valve chamber and then a handle mounting hole is drilled. After the left and the right water-tight gaskets are inserted into the left and the right water-tight gasket containment recesses, the ball valve is placed inside the ball valve chamber. Then, the external threads of the water inlet seat mating section are coated with a thread locking agent and screw fastened to the internal threads in the connection hole of the ball valve seat which causes the left and the right water-tight gaskets to rest against the two spherical surfaces of the ball valve. As such, the ball valves fabricated according to the method of invention herein retain forged material strength, while avoiding the occurrence of pitting, reducing defect rates, allowing easier finishing, lessening material wastage, lowering production costs and, furthermore, minimizing component fabrication and shortening the manufacturing time.

    Abstract: A vent valve for a thermostatic valve of a coolant circuit of an internal combustion engine has a ball with a radius and a diameter and serving as a sealing element, and a one-piece metal cage for the ball. The cage has a pot-shaped part with an inside diameter larger than the diameter of the ball, and a bottom having a valve opening surrounded by an outwardly projecting neck. The cage is shaped in one piece from an originally flat metal sheet by stamping, deep-drawing, and pressing, and the pot-shaped part has a height approximately the radius of the ball, and an edge abutted by a plurality of uniformly distributed tabs located on an axial extension of the pot-shaped part, the tabs having inwardly bent ends to retain the ball in the cage with play, the length of the tabs being greater than or equal to the height of the pot-shaped part.

    Abstract: A method of manufacturing metal casings, particularly gate valve casings, comprises, forming two casing shell half portions from a plate by holding the plate and forming a valve port in at least one of the plates with a forming tool, forming wall portions of the plate bounding the port into axially inwardly and axially outwardly extending collars bounding the opening and joining the two casing shell half portions together by a longitudinal weld which is accessible to ultrasonic and radiographic inspection to form a fluid- and pressure-tight casing. A device for carrying out the method comprises forming tools for imparting a shell, shaped to the plates and upper and lower dies which are provided with recesses for holding fast and forming or overforming flange-like collars. The collars may be formed with a forming tool having recesses for receiving displaced material forming the collars or a tool may be provided with upper and lower dies having working faces conformable to the shape of the respective casing part and capable of accommodating or receiving at least one forming tool, such as a roller or upsetting ram.
