摘要： PURPOSE:To manufacture easily a metallic torsion bar in a short time and in high material yield, by reducing radially a desired part of a metallic bar-shaped blank material by heating and stretching it, and providing a desired end-part work to the material after heat-treating the reduced part by quenching. CONSTITUTION:One end 1d of a part to be formed into a torsion bar of a blank material 1 such as a round bar of spring steel is heated by a heating coil 6 connected to a source 8 of high-frequency induction heating, and then is heat- treated by jetting cold air from a cooling nozzle 7. Next, the material 1 is heated to a prescribed temperature and stretched in the direction of an arrow F2 to reduce it radially by a stretching device 5a, 5b, and the radially reduced part is quenched to form a small diametral part 1b, while moving the heating coil 6 and the cooling nozzle 7 in the direction of an arrow F1 by driving a moving device 14. Next, after heat-treating the other end part 1e in the same manner as that of the part 1d, an end-part work such as a serration work is provided to the non-reducing parts of both end parts 1a, 1c to obtain a torsion bar.

摘要： PURPOSE:To facilitate forging operation and reduce the cost of dies and facilities by a method wherein rod end members made of solid metal material are connected to both ends of a main body of rod made of metal pipe. CONSTITUTION:A relay rod 1 is constructed such that a pair of rod end members 1b, 1b composed of solid metal member are connected to both ends of the main body 1a of rod made of metal pipe, and joints 10, 10 are attached to extremity ends of each of the rod end members 1b, 1b. Inner surfaces at the end parts 1c, 1c of the main body of the rod invade the rugged part 11 in form of plastic flow and also invade grooves 12, 12, resulting in that the main body of rod 1a and rod end members 1b, 1b are rigidly connected to each other in both circumferential direction and axial direction. Since each of rod members 1b, 1b can be machined under a condition in wich they are separated from the main body 1a of the rod, it is possible to make a small-sized forging facilities.
摘要翻译：目的：为了便于锻造操作，并且通过将由固体金属材料制成的杆端构件连接到由金属管制成的杆的主体的两端的方法来降低模具和设备的成本。构成：继电器杆1构造成使得由金属构件构成的一对杆端构件1b，1b连接到由金属管制成的杆的主体1a的两端，并且接头10,10附接到末端每个杆端部件1b，1b的端部。棒的主体的端部1c，1c的内表面以塑性流动的形式侵入粗糙部分11，并且还侵入槽12,12，导致杆1a和杆端构件1b，1b的主体在圆周方向和轴向方向上彼此刚性地连接。由于杆构件1b，1b中的每一个可以在与杆的主体1a分离的条件下加工，所以可以制造小型的锻造设备。

摘要： PURPOSE:To carry out the effective surface hardening of a spring with a simple apparatus even when the spring has a complex shape by connecting a high frequency power source to the spring before or after forming and, directly supplying high frequency current to carry out hardening. CONSTITUTION:For example, in the hardening of a spring before forming, roll electrodes 2, 3 are rolled while in electrical contact with a spring material 1a. The electrodes 2, 3 are connected to a high frequency power source 4, and high frequency current is supplied to the electrodes. The material 1a, chiefly the surface part generates heat quickly and attains to a high temp. The material 1a is then coiled to obtain a coil spring 1, and the surface is quenched by spraying cooling water on the surface or by other method. The surface part of the spring 1 can be heated up to a uniform depth, so hardening up to the uniform depth is carried out.

摘要： PURPOSE:To produce a superelastic spring having a shape memory effect of desired shapes by forming a shape memory alloy to a prescribed shape in a temp. region below the Ms point and heating the same to temp. above the Md point while holding the alloy restrained in this shape, then cooling the same to temp. below the Md point. CONSTITUTION:In the case of producing a coil spring, a blank material (a) of a shape memory alloy is wound along the spiral grooves 2 formed on the outside circumferential part of a core metal 1 in a temp. region below the Ms point of the shape memory alloy, and both end parts thereof are fixed by means of fixing fittings 3. While the coil spring (b) formed in this way is held restrained by the metal 1 and the fittings 3, it is held for 15-30min at temp. above the Md point. Thence, it is cooled as quickly as possible to temp. below the Md point.

摘要： PURPOSE:To produce a superelastic spring having a shape memory effect of desired shapes by forming a shape memory alloy to a prescribed shape in a temp. region above the Md point, and cooling the same to a temp. region below the Md point. CONSTITUTION:Electricity is conducted from an electric power source part 1 through electrodes 2, 2 to a blank material (a) of a shape memory alloy to heat the material up to a temp. region above the Md point of the shape memory alloy, thence the material is formed to a coil spring (b). The heating temp. is 200-1,000 deg.C if the shape memory alloy is of Ti-Ni type and 450-900 deg.C if it is of Cu-Zn type. After this coil spring (b) is cut to respective single pieces, the springs are dipped in cooling liquid 3, and are cooled to a temp. region below the Md point.

摘要： PURPOSE:To improve dimensional accuracy of slope and roundness by moving a bar material in longitudinal direction, rolling it to a tapered polygon by plural rolles, and rolling it to a tapered circular section by rotating plural rolls around the passage. CONSTITUTION:A bar material (a) is moved in longitudinal direction through a chuck 3 in rough forming process. Then, it is rolled by rolls 4 by pressing down rolls 4, 5 according to the amount of movement to make the sectional form near a square, and rolled by rolls 5 to make the sectional form an octagon. Thus, a tapered intermediate material (b) that has a round basal part and octagonal tip is formed. Next, in finishing process, a roll housing 7 provided with three drum- shaped rolls 9 is rotated around the moving passage of the intermediate material (b). The intermediate material (b) is rolled to tapered form having round section controlling the rolling reduction of rolls 9 according to the amount of movement.
