| The invention relates to a method and a press cylinder device for producing a hollow body consisting of a tubular workpiece (10) comprising a step (20). A conical area (12) is embodied on the tubular workpiece. Said area is heated in a specific manner. An axial compressing force (f) is subsequently exerted on the workpiece in such a way that the heated conical area (12) is compressed and shaped to form the step (20). Shaping of the conical area and compressing can be carried out on a press cylinder device. | ||||||

Pressure is applied to a cylindrical material (41) in the axial direction so as to perform squeezing process by extrusion, thereby narrowing the forward end of the material (41) with respect to the direction in which the pressure is applied. Obtained as a result of extrusion is an intermediate molding (46) having a cylindrical portion (43), a slanted portion (44), which is formed as a continuous, integral body with the cylindrical portion (43) and has a gradually reduced diameter, and a small diameter cylindrical portion (45), which is formed coaxially with the cylindrical portion (43) and has a diameter smaller than that of the cylindrical portion (43). The slanted portion (44) is flattened by applying pressure from the end of the cylindrical portion (43) of the intermediate molding (46) in the axial direction in the state where the outer and inner cylindrical surfaces of the cylindrical portion (43) and the outer cylindrical surface of the small diameter cylindrical portion (45) are restrained. A first housing (11) is formed by forming the cylindrical portion (43), the slanted portion (44) and the small diameter cylindrical portion (45) respectively into a body portion (14), bottom portion 17 and a coupling portion 23. Compared with a case where a housing is forged from a material in the shape of a solid column, a first housing according to the present invention can be formed with a substantially reduced pressure and is more convenient to form. As it is formed by forward extrusion, high precision formation is possible without the need of cutting work. |

| The invention relates to a method for producing an inner profile (4) of a sleeve-type metal outer part (1) by rotary kneading. The inner profile (4) corresponds at least essentially to an outer profile (5) of an inner part (2) which can be inserted into the outer part (1) in the longitudinal direction of the same at least in sections, in the area of the inserting sections of the two parts. An outer profile (5) is provided on the inner part (2) and the inner part (2) is inserted into the outer part (1) at least in sections. A rotary kneading tool (3) which acts on the outer part (1) from outside is then used to produce an inner profile (4) on the outer part (1) which corresponds to the outer profile (5) of the inner part (2). Alternatively, the inner profile (4) of the outer part (1) can be used to produce the outer profile (5) of the inner part (2) using a rotary kneading tool (3) which acts upon the outer part (1) from outside. | ||||||

An dünnwandigen Rohren (1) od. dgl. Hohlprofilen sind an besonders beanspruchten Stellen, wie Schweißungen, Gewinden, größeren mechanischen oder chemischen Belastungen, verstärkte Wanddicken (2,3) notwendig. Hierzu ist das Rohr (1) an den gewünschten Abschnitten (2,3) aus seinem Wandwerkstoff heraus verdickt. Diese Wandverdickung (2,3) ist auf der Rohrinnenfläche ausgebildet. Um dieses Rohr : herzustellen, wird ein dünnwandiges Rohr (1) mit größerem Durchmesser durch Verformung an den zu verdickenden Abschnitten (2,3) im Durchmesser reduziert und in der Wanddicke verstärkt. Durch weitere Ziehvorgänge wird dann der endgültige gleichmäßige Außendurchmesser des Rohres gewonnen. |

| The present invention provides a manufacturing method of a joint cap for a concrete pile which is equipped with a plate and has a guide ring formed on the joint cap by comprising: a step for forming a protrusion having a thickness thinner than that of a plate by cutting the lower part of the inner edge of a through hole of the plate; and a step for forming the guide ring which is protruded vertically from the plate by using an upper and a lower forging mold for forging the protrusion. The present invention has effect of manufacturing a joint cap for a concrete pile with high marketability since a guide ring is formed at a right angle to a plate by forming a protrusion on the edge of a through hole of a plate and by using a lower forging mold for pushing and inserting the protrusion into a right-angled groove of an upper forging mold. The present invention provides a method that is capable of simply forming a guide ring on a plate at low costs and which minimizes defect rate by forming a right-angled groove at the inner edge of the lower end of an upper forging mold for supporting and protruding a protrusion and by preventing the tearing-off or crush of the protrusion due to an upper curved protrusion, a middle curved concavo part, and a lower curved protrusion formed on the outer edge of the upper end of a lower forging mold. | ||||||
