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。

摘要： A die button flush mounted in the cavity surface of a lower one of two hydroforming dies has a backup plunger received therein that forms a part of this surface when the plunger is in a hydroforming position. A slug ejector received in the lower die also forms a part of this surface and with a tubular part enclosed in the cavity formed by the dies, hydroforming fluid under pressure is supplied to the interior of the part and also to separately act on the plunger. The fluid pressure moves and holds the plunger in its hydroforming position while forming the part to the die cavity surface. The fluid pressure on the plunger is then exhausted allowing the fluid pressure in the part to stretch a portion of the part into the die button while also forcing the plunger to a position that limits this stretching to prevent piercing. The fluid pressure in the part is then reduced to a pressure just sufficient to pierce the stretched portion and the plunger is then allowed to further retract to a position allowing the reduced pressure to pierce a slug onto the plunger. The part is then removed from the die cavity and the plunger is returned to its initial position with the slug thereon where the slug is then ejected from the lower die through an opening in the lower die cavity surface.

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： 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.
摘要翻译：液压成形设备设置有可伸缩部件定位器，当可伸缩部件定位器被延伸以接收和保持待加压成形的管状部件的端部部分时，并且因此当模具打开时支撑并保持液压成形模具之间的部件。安装在单独的电梯上的密封单元具有可缩回的密封载体，并且当密封单元升高并且当部件被保持时，初始接合相应的管状部件端部时，适合密封载体。部件定位器适于释放部件的端部并且缩回到密封载体的方式之外，以便使密封载体然后在部件的相应末端部分上进一步前进到紧邻该部件的端面的位置同时在模具闭合之前使部件纵向对准模具。密封单元电梯适合于将具有管状部件的密封单元降低到当模具关闭时将部件的端部与模腔的开口端对准的位置。并且可伸缩部件定位器在部件的液压成形和密封单元电梯的密封单元的高度成形之后，适于在将密封件离开之前再次将现在的液压成型部件伸出并夹紧到零件定位器那个部分。
