  • Patent number: 6021562
    Abstract: A new tooling for use in a progressive die machine for the installation of self-clinching fasteners onto a sheet of material is provided. It is a complete tool easily mounted into the die during its construction and easily removed for service. Its compact size provides a minimal space between working stations on the die, and its height and stroke are minimized so as not to interfere with other operations on the die. It may be easily configured to allow for insertion of fasteners from either the top or the bottom, and is capable of correctly providing a fastener for insertion upon every cycle of the press. This is accomplished by use of a special bisected bushing which securely holds and positions each fastener in place prior to and during insertion. A replaceable force-limiting material is incorporated in the tooling above the anvil in order not to disrupt the progressive die press should fasteners or materials of excessive thickness be encountered.
