How Robotics are Helping Shot Blasting in Different Manufacturing Segments

A robotic blaster is a conjunction of a shot blasting system and a multiple-axis robot engineered especially for suiting select applications. The robotic blaster can be used for distinct blast cleaning activities such as deburring, desanding and shot peening. Usually, the automobile makers use this compact, efficient, and noise-protected blaster to deburr and lay surface finishes on the gearbox housings comprising of magnesium alloy in short span, which can be 26 seconds.

The robot having a double-gripper can come in handy for handling the parts from parallel pressure die casting lines of two and then put them into the shot blasting system. The bell and the gearbox housings are shot blasted by up to six high-performance blast wheels in shot blasting which uses a robot for operation. In fact, the robot inserts the magnesium parts onto the wire mesh units, which can assure auto-processing of various parts with intricate geometries in a constant flow-through operation.

Such equipment can be of many different sizes and dimensions and can be tailored in order to accommodate shot blasting needs. For instance, one such customized conveyor belts can have up to 8 blast wheels providing many different angles for attaining common coverage in shot blasting.

The concept of robotics can be duly chosen by the die casters also who produce die cast aluminum components for the automobile segment or other segments. The customized system for shot blasting can give the die casters and the end customer a replicable, documentable, as well as affordable blast cleaning solution. In fact, inserting, transporting and off-loading the die cast aluminum parts through a conveyor could occur on twin tracks leading to a rise in the throughput rates. The procedure may be sensitive to metal shot impingement also.

As for the throughput rates, the time frame to insert the component into the conveyor are usually in between 6 to 12 seconds a track. Once the shot blasting procedure is done, the cup-shaped casting can go through a post-separation in which they are rotated many times over to make sure the residual blast media is completely removed from the casting.

In addition, there is also cell-manufacturing concept in shot blasting using robots. One blasting equipment in cell manufacturing can give more than one casting cells. The blasting equipment for making a casting cell give shot cycle spans, increased component variability, and need little manufacturing space. For instance, various die cast aluminum parts to have been separated, weighing 35 kilos each, can be moved from the casting cells to the shot blasting equipment where a robot puts them into the blast cabinet.
