Lightweight Spot-Welding Gun a Boon for HSS Applications
The Gortite VF door from Dynatect Manufacturing, Inc., New Berlin, WI, is a high-speed, automatic roll-up door intended for safety in machine guarding and automated work environments. It separates harzardous processes from people and equipment. Also, it can contain process-driven hazards such as weld sparks, fluid splatter and debris. By eliminating the extra buffer needed for light curtains to create a safety zone, the barrier created by the Gortite VF Door minimizes the impact on available machine floor space.
Dengensha America, Bedford, OH, has developed a high- force, lightweight, reduction-gear X-Gun that proves extremely effective for resistance-spot welding of high-strength steels. With its new high-torque reduction gear, it can achieve an electrode force ranging of 4.8 to 7 kN. The new, proprietary lightweight design features an aluminum gun arm; total weight ranges from 90 to 97 kg.
Key specs: customer-specfied door-opening height and width of 3 to 16 ft.; 44 in./sec. standard speed; numerous sensor and switch options; continuous operation at as many as two complete cycles per minute; optional traveling photo-eye (bot- tom-edge sensing and reversing).
