摘要： A method for making a direct acting tappet in which an oil groove and interior structure defining a weld interface are formed in a cupshaped body by a rolling process, the body is heat treated, a web and hub structure is positioned against the weld interface and the resulting assembly is subjected to a localized, capacitive discharge welding process in the weld interface area. The weld interface is formed to a specific shape to enhance the integrity of the weld. Further, a baffle member can be assembled to the web and hub structure prior to its positioning within the body member.

摘要： An orthopedic implant and method for forming same includes providing a forging die having a punch and a split die. The split die is movable between an opened state, where first and second die portions are spaced apart to allow for removal of a formed orthopedic implant element from within the cavity portions, and a closed state, where the first and second die portions are secured together and the cavity portions cooperate to define a cavity to form the orthopedic implant element therein. The split die is closed and a billet of biocompatible material is provided in the cavity and the punch is moved to deform the billet in the cavity to forge the orthopedic implant element in the cavity while the first and second die portions are substantially fixedly secured together when the split die is in said closed state.
摘要翻译：矫形植入物及其形成方法包括提供具有冲头和分开模的锻模。分开模具可以在打开状态之间移动，其中第一和第二模具部分间隔开以允许从空腔部分内移除形成的矫形植入元件，以及闭合状态，其中第一和第二模具部分固定在一起并且空腔部分协作以限定空腔以在其中形成整形外科植入元件。分开的模具是封闭的，并且生物相容性材料的坯料设置在空腔中，并且冲头移动以使空腔中的坯料变形，以将矫形植入元件锻造在空腔中，同时当第一和第二模具部分基本上固定地固定在一起时，分裂模具处于所述关闭状态。
