    • A small-diameter metallic conduit bending machine comprises a stationary frame with a guide surface, a bending member for pressing a metallic conduit against the stationary frame, and an actuator for moving the bending member via a lever. One end of the lever supporting the bending member is pivoted to the stationary frame at a position lying substantially on the axial center line of the metallic conduit within a central portion of a bend section where the metallic conduit is bent so as to lie along the guide surface of the stationary frame. Thus, the metallic conduit can be readily inserted between the guide surface and the bending member, and two successive bending works can be completed through one action.

    • A small-diameter metallic conduit bending machine includes a stationary frame. The stationary frame made of bar stock or pipe stock is shaped so as to substantially conform to a finished metallic conduit. The stationary frame includes a bending section which has in its lengthwise direction a curvature smaller than the bend radius of the metallic conduit and in its widthwise direction a guide surface substantially orthogonal to the bend plane of the metallic conduit. A bending member whose outer peripheral surface faces the guide surface is disposed movably toward the stationary frame so that the metallic conduit can be bent so as to lie along the guide surface. The bending member is moved by an actuator when the actuator is in its pulling stroke.
    • 小直径金属导管弯曲机包括固定框架。 由棒材或管材制成的固定框架成形为基本上符合成品金属导管。 固定框架包括弯曲部分,该弯曲部分在其长度方向上具有小于金属导管的弯曲半径的曲率,并且在其宽度方向上具有基本上垂直于金属导管的弯曲平面的引导表面。 外周面与导向面相对的弯曲构件朝向静止框架移动地设置,使得金属导管能够沿导向面弯曲。 当致动器处于其牵引行程时,弯曲构件由致动器移动。

    • The present invention provides a device for bending thin metallic pipes suitably used as a fuel supply pipe, brake pipe and the like of an automobile, which are bent at a plurality of portions thereof not in the same direction but in three-dimensional directions. The device according to the invention includes a stationary mold form having a first and a second bending section to the shapes of which a metallic pipe is bent and a guide member erected upright on the mold form at the second bending section, a bending member arranged outside the mold form and movable toward the latter for bending the metallic pipe, a rotor for rotating the bending member and an actuator for operating the rotor through a wire. The advantages of the invention are that unlike the conventional device, the bending member located outside the mold form is attached to the rotor which is rotated by the actuator through the wire, the interference of the actuator with the metallic pipe or other parts of the device or with another actuator is prevented and the structure of the device is simplified.

    • A small-diameter metallic conduit bending machine includes a stationary frame which is shaped so as to substantially conform to a finished metallic conduit. A bending member is provided movably toward the stationary frame from thereoutside to bend a metallic conduit. To prevent the bending member from interfering with the metallic conduit which is moving as the result of the bending process of a preceding stage, an actuator is provided to remove the bending member from the moving area of the metallic conduit. That is, the binding member is made movable toward the stationary frame and retractable from the moving area of the metallic conduit.
    • 小直径金属导管弯曲机包括固定框架,该固定框架的形状基本上与成品金属导管相符合。 弯曲构件从外侧朝向固定框架可移动地设置以弯曲金属导管。 为了防止弯曲构件与由于前一级的弯曲处理而移动的金属导管干涉,提供致动器以从金属导管的移动区域移除弯曲构件。 也就是说,装订构件能够朝向静止框架移动并且可从金属导管的移动区域缩回。
