136 THE DISTRIBUTOR’S

136 THE DISTRIBUTOR’S LINK STEVEN SHERMAN RIVETNUTS: PULL AND PRAY GIVES WAY TO A BETTER SOLUTION from page 30 because variables such as air pressure, oil level, hydraulic seal conditions and operator experience can all impact the outcome. ¤ Pneudraulic Spin-Pull Tools - Pneudraulic spinpull tools are available in two basic variations based on the way the tool is stopped in the pull direction. Spin- Pull to Stroke tools are positively stopped by placing a limit on the backward stroke. In this case, the tool is always pulling at full pressure. The tool works best when it is set for a particular rivetnut size and metal thickness, which requires calipers and trained personnel to define and enforce the setup. With a Spin-Pull to Pressure tool, there is no positive stop and the backward stroke is limiting the air pressure via a valve on the tool. Since there is a marginal correlation between the air pressure and the dynamic load, a reduction in air pressure equals a decrease in applied force. That means the tool is essentially starved of air pressure, and hopefully comes to a complete set just before the air pressure is consumed. While this works well with a variety of rivetnuts and metal thicknesses – it’s not precise Taking Spin-Pull Technology to the Next Level The newest method of riveting, the Spin-Pull to Measured Force and Measured Stroke, uses an electric drive motor and 18-volt battery. By removing the pneumatic line, the pull force can be regulated electronically. Sensors powered by the battery measure and control the process precisely. The actual stroke is measured by a linear light sensor and the actual force is measured within 1% of accuracy by a load cell. In addition to this, force and distance limits can be programmed into the tool by the manufacturing engineer and a memory card can be added to store the force and stroke of each rivetnut installed for future use. If a WiFi card is also added, the pass/fail data can be sent to MIS systems warranty tracking. This electronic solution eliminates the uncertainties of pneudraulic methods. The result is a robust, repeatable process that delivers greater accuracy for maximizing efficiency as well as minimizing downtime, rejections and claims.
