摘要： A gutter outlet punch for punching an outlet in a rain gutter. The gutter outlet punch has a female die and a male cutting die mating with the female die with the rain gutter positioned therebetween. The male cutting die is attached to a rod. A ratchet permits incremental, one way movement of the male cutting die toward the rain gutter. A ratchet handle permits one-handed operation of the ratchet. A ratchet release allows the male cutting die to be moved away from the rain gutter. An alignment mechanism permits alignment of the rain gutter with the male cutting die in two alternate orthogonal orientations. A housing surrounds the female die and encloses the male cutting die to prevent contact with the operator when the apparatus is not in use. An automatic mechanism ejects the punched-out slug from the apparatus.
摘要翻译：用于冲洗雨水沟中出口的沟槽出口冲头。沟槽出口冲头具有阴模和与阴模配合的阳切割模，其间设有雨沟。公切割模附着在杆上。棘轮允许男性切割模块向雨水沟增量单向运动。棘轮手柄允许单手操作棘轮。棘轮释放允许男性切割模具从雨沟移开。对准机构允许雨沟与雄切割模具在两个交替的正交取向中对准。壳体围绕阴模并且包围阳切割模以防止在不使用设备时与操作者接触。自动机构将冲出的塞子从设备中弹出。

摘要： The method of manufacturing a heat exchanging fin is able to restrict forming wrinkles and ring marks in the heat exchanging fin. The method comprises the steps of: forming dome sections having diameters greater than the diameters of collared-through-holes and which are projected from one side face of a thin plate, and a plurality of circular recesses having diameters greater than of the dome sections, each of which encloses one of the dome sections, the circular recesses being depressed toward the opposite face of the thin plate; forming the dome sections and the recesses into truncated cone-shaped sections in a plurality of steps; forming a through-hole in each of the truncated cone-shaped sections; forming edges of the through-holes into collars; and forming a flange at a front end of each of the collars.

摘要： A wheel spindle flange (and the like) has stud holes with soft surface hardness formed therein which permit non-rotational splines, studs and the like to be press-fitted therein with minimal press force at a centered press zone established between intentionally formed and dimensioned counterbores within the flange to minimize flange distortion and lateral run out of the spindle.
