摘要： Hydroforming apparatus is provided with retractable part locators that are adapted when extended to receive and hold end portions of a tubular part to be hydroformed and thereby support and hold the part between the hydroforming dies when the dies are open. Seal units mounted on separate elevators have a retractable seal carrier and the seal carriers are adapted when the seal units are elevated to advance and initially engage the respective tubular part end portions while the part is being so held. The part locators are adapted to release the end portions of the part and retract out of the way of the seal carriers to permit the seal carriers to then further advance on the respective end potions of the part to a position closely adjacent the end faces of the dies while also centering the part lengthwise with respective to the dies prior to die closure. The seal unit elevators are adapted to lower the seal units with the tubular part to a position aligning the end portions of the part with open ends of the die cavity when the dies close. And the retractable part locators, following the hydroforming of the part and elevation of the part with the seal units by the seal unit elevators, are adapted to again extend and clamp the now hydroformed part to the part locators prior to disengagement of the seal carriers from the part.

摘要： The seal units that form part of a hydroforming apparatus that further includes dies for hydroforming parts are each provided with a tubular part locator for locating and clamping a tubular part in alignment with the seal unit. The part locator basically comprises a locator member, a pair of pivot arms and a backup member wherein the locator member and the pivot arms together with the seal unit are supported by an elevator that aligns the seal unit and the locator member with the hydroforming dies when the latter close on the tubular part. The locator member has a concave surface and guide surfaces wherein the concave surface has a shape conforming to the outer surface of the part and the guide surfaces are adapted to guide an end portion of the tubular part onto the concave surface of the locator member and thereby into alignment with the seal unit. The pivot arms each have a concave surface also conforming to the outer surface of the part and are adapted on pivoting to clamping positions to clamp the end portion of the part on the concave surface of the locator member. The backup member is adapted to hold the pivot arms in their clamping position during hydroforming of the part and may also include a concave surface that is adapted to clamp the end portion of the tubular part on the concave surface of the locator member in cooperation with the concave surface of the pivot arms.
摘要翻译：形成液压成型装置的一部分的密封单元还包括用于液压成型部件的模具，每个设置有用于定位和夹紧与密封单元对准的管状部件的管状部件定位器。部件定位器基本上包括定位器构件，一对枢转臂和支撑构件，其中定位构件和枢转臂与密封单元一起由电梯支撑，电梯使密封单元和定位构件与液压成形模对齐，后者靠近管状部分。定位器构件具有凹面和导向表面，其中凹面具有与部件的外表面一致的形状，并且引导表面适于将管状部件的端部引导到定位构件的凹面上，从而与密封单元对齐。枢转臂各自具有也与部件的外表面一致的凹面，并且适于枢转到夹紧位置，以将部件的端部夹紧在定位构件的凹面上。支撑构件适于在部件的液压成形期间将枢转臂保持在其夹紧位置，并且还可以包括凹形表面，该凹面适于将管状部件的端部部分与定位器构件的凹形表面枢转臂的凹面。

摘要： A method for cutting an "O" ring retention groove around the cutting edge of a hydropiercing die button. A groove machining tool is given a convex curved end surface the radius of which is slightly less than or, at most, substantially equal to the tightest concave radius that the end surface will have to sweep through as the groove is cut. Consequently, an accurate, slightly curved groove bottom surface is created for the "O" ring, while the machining tool will not bind as it moves through the tightest concave portion of the cutting path.
摘要翻译：一种用于在加氢模具按钮的切割边缘周围切割“O”形环保持槽的方法。凹槽加工工具具有凸起的弯曲端面，其半径略小于或至多基本上等于当凹槽被切割时端表面必须扫掠的最紧的凹入半径。因此，为“O”形环产生精确的略微弯曲的凹槽底面，而当加工工具移动通过切割路径的最紧的凹入部分时，加工工具将不会结合。
