Standard tooling options are available for both manual and automatic PEMSERTER® presses. The typical punch and anvil components for manual presses are used to install a variety of self-clinch fasteners in a workpiece. Turret anvils for nuts and studs allow quick change of fastener sizes to allow rapid installation of different size fasteners in the workpiece. When a workpiece flange and fastener location prohibits the use of standard tooling, the use of top or bottom mount, reverse flange anvil holders will often solve the installation problem.
Standard automatic tooling for the Series 2000 press is available for commonly used stud, nut, and standoff fasteners. Injector style for FH and HFH studs (limited to 1" length), and vacuum style top feed for dash length to 30 are used to increase productivity and lower installation costs. Nut installation tooling is available in both top and bottom feed configurations. The choice is often dependent on the workpiece configuration and layout. Top feed automatically presents the fastener to a punch that "spears" the fastener and carries it down to the workpiece for installation. Bottom feed presents the nut to an anvil module where the workpiece is placed over the fastener and the punch applies the installation force.Sometimes the workpiece configuration provides a challenge for fastener installation and standard tooling requires modification or an entirely new design to be effective. Several custom designs are profiled below.
This bottom feed tooling was designed for large S nuts installed on the inside of a flange as well as the flat of a workpiece.
Bottom Feed Injector
Sometimes there are applications where the fastener has to be installed "from the inside out" of the workpiece and top feed technology is not doable. However, utilizing the current top feed injector technology, modified to work installed up side down in the anvil position the installation is accomplished. The fastener is processed from the bowl to the injector. The workpiece is placed over the stud and while maintaining fastener alignment with the spotting light, the punch travels over the fastener to the workpiece to complete fastener installation.
The patented QX turret tool system includes four anvil tools that can be manually rotated quickly into position. One is dedicated to the automated feed tooling for the highest-volume fastener installation, while the others can be used to install up to three different products manually. Color coded parts trays and anvils make it easy for a single operator to install up to four different fasteners while handling the workpiece only once.
Simplified setup and verification of installation is achieved by the system utilizing the standard touch-screen feature in Series 2000 presses. The system further detects which station is in the "install" position and prevents operators from proceeding unless the correct station is locked in position. This serves to maintain and confirm proper sequence for fastener installation as programmed. Multiple jobs can be saved for future quick setups.
