摘要： Method and apparatus are disclosed wherein a required threaded hole is formed in a hydroformed part with a single tool while the part remains in a hydroforming die cavity. In forming the threaded hole, a hole is first pierced in the wall of the part and then an annular region of the part extending about the hole is extruded inwardly to form an integral tubular neck defining a hole of predetermined depth. The hole is then expanded in a sizing operation to a diameter determined by the required thread to be formed therein by material displacement and the required thread is then formed in the wall of the hole in a material displacing manner.

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： A fastener nut for hydroformed parts comprises a nut body for receiving a threaded fastener and a locking ring with depending fingers that is received on the nut body. The nut body is adapted to pierce and then form a collar thereabout in a hydroformed part while the part remains in a die cavity under hydroforming pressure. The nut body and the collar formed thereby have a configuration that prevents turning of the locking ring while permitting turning of the nut body relative to the locking ring on full insertion of the nut in the collar, and a cam surface on the nut body that on partial turning of the nut body then forces the locking ring into locking engagement with the collar to thereby attach the fastener nut to the hydroformed part.

摘要： A hydrotapping power unit is disclosed that is operable to hold a hydrotapping tool in a home position adjacent a part while the latter is being hydroformed in a die cavity, to then advance the tool to pierce a hole in the hydroformed part while the part remains in the die cavity and under pressure and then continue to advance the tool to inwardly extrude the part about the hole, to then further advance while also rotating the tool at a feed rate equal to the thread pitch of the tool to thereby form a thread in the pierced hole, and finally retract while also rotating the tool but in the reverse direction and at the same feed rate to release the tool from the threaded hole. The power unit for performing these operations includes a linearly moveable shaft for holding the tool, a powered device for rotating the shaft, another powered device connected to the shaft by a lead screw connection having a thread pitch equal to that of the tool, and a third powered device that is adapted to intercept and prevent shock loading on the tool from the piercing operation and thereby on the shaft from reaching the lead screw connection.

摘要： Hydroforming apparatus includes in-die hydropiercing apparatus with easy and precise adjustment of the positioning of a backup plunger that is received in a die button and is positioned in a hydroforming position, a prepiercing position, a piercing position, and a slug ejecting position that may be outside the plunger or may be the hydroforming position. Wherein the plunger is required to be precisely positioned and held in the prepiercing position in the die button in order to obtain a desired prepiercing action without prematurely piercing the hydroformed part. The in-die hydropiercing apparatus has a plunger actuating hydraulic cylinder that moves the plunger to the different positions and a cam actuating hydraulic cylinder that positions a cam in determining the prepiercing position of the plunger. The cam actuator includes an adjusting device that provides for easily adjusting positioning of the plunger with the cam in the required prepiercing position and the cam with its hydraulic actuator also acts to hold the plunger in the prepiercing position thereby relieving the plunger actuating hydraulic cylinder of this duty.

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： A punch for piercing and sealing hydroforming parts has a roll forming surface that produces an internal rolled edge portion in a formed part immediately following the punch piercing the part wherein the rolled edge portion acts to effect a tight high pressure seal between the part and the punch as the punch continues to form a required hole in the part. The roll-forming surface extends either partially or completely about the punch in determining the extent of the rolled edge portion in the part that it produces and is located between an end portion that effects the piercing operation and a larger finishing portion that completes the formation of the required hole.
