TWS91 Weld Shaving System by PushCorp | Automated Weld Removal

TWS91

Tracked, Weld-Shaving System

The PushCorp TWS91 is an automated solution for the rapid removal of weld beads above a panel surface. The TWS91 System is composed of five major components: the Track (either Flex or High-Flex), the Drive Carriage, the Weld Shaver, the Control Umbilical, and the Control Console. A Weld Shaver (SWS100-3.7-XXmm) is moved along the Track by the Drive Carriage. The customer controls everything through the Control Console.

The Track is attached to a steel panel via eight rare earth magnets. Both types of track (either Flex or High-Flex) are designed to conform to the curvature of the panel. The 35 in. (0.9 m) High-Flex Track will conform to a 80 in. (2 m) bend radius. The 70 in. (1.8 m) Flex Track will conform to a 400 in. (10 m) bend radius, allowing fewer track sections to be utilized.

The Drive Carriage travels along the Track and moves the Weld Shaver over the weld seam. It also provides the compliant force to keep the Weld Shaver in contact with the panel. The Drive Carriage is motivated by a gear-reduced servo motor with closed-loop feedback. This allows the user to easily control and monitor the desired feed rate.

One of three different configurations of the Weld Shaver (SWS100-3.7-20mm, SWS100-3.7-39mm, or SWS100-3.7-59mm) is installed on the Drive Carriage, dependent on the width of the weld seam to be removed.

All configurations of the Weld Shaver share the same design features, differentiated only by the cutting width. A high-torque servo motor drives a series of slotting cutters through a belt reduction. The slotting cutters utilize standard carbide inserts. Utilizing a servo motor allows the cutting speed to be accurately set and monitored and the cutting effort to be monitored.

The Control Console allows the user to completely control and monitor the weld-removal process from a safe distance. The Control Console has displays for cutter speed, cutter effort, carriage speed (feed rate), carriage effort, applied pressure, and retract pressure. It has controls for enabling the Drive Carriage and the Weld Shaver, as well as setting the cutter speed, carriage speed, and orientation.

The Control Umbilical connects the Control Console to the Drive Carriage. All of the electrical power cables, control signal cables, and pneumatic air supply lines to the Drive Carriage are protected inside the Control Umbilical’s fire-retardant, crush-resistant outer tube.

The TWS91 System offers vastly reduced production times while improving quality and safety over manual grinding.
