摘要： PURPOSE: To simply and cheaply form a large size pipe at the under part of a metallic pipe end, by holding the upper end of said pipe with a holding die in order to add a hydraulic pressure in said pipe by simultaneously lowering said holding die.
CONSTITUTION: A sudden hydraulic pressure 2 is added into a metallic pipe 1 of which an under part is fitted loosely into a vertical die 3 and an upper part is fitted closely into a holding hole 4 of a holding die 5. A part of the pipe 1, except the upper end of the pipe 1 held by the holding die 5, expands by the hydraulic pressure 2 causing the increase of its dia. and the decrease of its length. At this time, when the die 5, holding the upper end of the pipe 1, is lowered to press the upper end of the pipe 1 with the top of the holding hole 4 of the die 5, the lower outer peripheral part of the pipe 1 is made to fit closely to the inner peripheral surface of the die 3 so as to form a expanded pipe 6. Simultaneously, a stepped or tapered pipe-part 8 is formed between the expanded pipe 6 and the small dia. pipe 7 at the upper end of the pipe 1 held by the holding die 5.

摘要翻译：目的：为了在金属管端的下部简单且廉价地形成大尺寸管，通过用保持模保持所述管的上端，以通过同时降低所述保持模而在所述管中增加液压。构成：在金属管1中加入突然的液压2，其金属管1的下部松散地装配到垂直模3中，上部紧密地装配到保持模5的保持孔4中。管的一部分如图1所示，除了由保持模具5保持的管1的上端之外，液压2扩大，导致其直径增大。并减小其长度。此时，当保持管1的上端的模具5下降以将管1的上端与模具5的保持孔4的顶部按压时，管的下部外周部使其与模具3的内周面紧密配合，形成扩径管6.同时，在扩管6与小直径面之间形成阶梯状或锥形的管部8。在管1的上端由保持模5保持的管7。

摘要： PURPOSE:To stick surface material firmly on the outer face of a core cylinder by a simple process by expanding the metallic core cylinder covered with a cylinder of surface material at an important position by bulging. CONSTITUTION:The body 1a of a core cylinder 1 is covered with a cylinder 2 of surface material made of properly vulcanized rubber etc. having proper hardness and coefficient of friction. The core cylinder 1 covered with the cylinder 2 of surface material is inserted to forming holes 3a, 4a of a bulging device. When pressure oil is sent into the feeding hole 6a of a plug 6, the body 1a of the core cylinder is expanded and the cylinder 2 of surface material adheres firmly to the body 1a. After completion of bulging, the core cylinder is taken out, and the surface of the cylinder 2 of the surface material is ground to form a feed roller having a necessary diameter.

摘要： PURPOSE:To enable easy manufacture of a cam shaft that has a large ratio of diameter of the shaft to the larger diameter of the cam part by combining bulging and drawing. CONSTITUTION:A metallic tube 1 having diameter equal to shorter diameter of the cam part of desired cam shaft is bulged, and projection 2 of the cam part is formed. Then, the shaft 3 and bearing parts 4, 4 are formed by drawing by roller rolling or press working to obtain a cam shaft 5. In this way, only the projection 2 is bulged by bulging, and accordingly, working is easy and thickness deviation is small. At the same time, the side of the cam part is not slanted. Consequently, a cam shaft having a large ratio of diameter of the shaft 3 to longer diameter of cam part can be manufactured easily.
摘要翻译：目的：通过组合凸出和拉伸，可以方便地制造具有大直径的轴与凸轮部分的较大直径的凸轮轴。构成：具有与期望的凸轮轴的凸轮部分的直径相等的直径的金属管1膨胀，并且形成凸轮部分的突起2。然后，轴3和轴承部分4通过辊轧或压力加工拉伸而形成，以获得凸轮轴5.这样，只有突起2由于凸出而膨胀，因此工作容易并且厚度偏差是小。同时，凸轮部分的侧面并不倾斜。因此，可以容易地制造具有较大的轴3的直径与凸轮部的较长直径的凸轮轴。

摘要： PURPOSE:To obtain a thickness having a sufficient strength even if a groove is worked in the outside periphery of a small diameter part by forming the small diameter part by a diameter reducing so that it becomes a sufficient thickness, and thereafter, executing a thickness changing to a shaft part, when manufacturing a steering shaft of an automobile. CONSTITUTION:A tubular stock is brought to drawing so that a thickness of a correct strength is obtained as a small diameter part 2 for executing a grooving such as a serration, etc. to the outside periphery, and the small diameter part 2 and a screw shaft part 3 are formed. In this case, when a tubular stock having 4mm. thickness is used, a thickness of the small diameter part 2 and the screw shaft part 3 becomes about 5mm. and about 5.5mm., respectively. Subsequently a mandrel 4 is inserted into a shaft part 1, the shaft part 1 is made to pass through a die 5, it is moved relatively in the axial direction, and a thickness of the shaft part 1 is elongated in the axial direction by a thickness changing, and worked to a prescribed thickness. In this way, the small diameter part 2 having a sufficient strength even if a grooving is performed is provided, and the shaft part 1 is thin to the necessary minimum limit, and a durable work-hardened steering shaft is obtained without increasing weight.
