This was a custom order for a small shop who specialize in manufacturing and refurbishing trailer covers. The device wasn't made to become a mass produced product and therefore was designed to be manufactured as a one-off piece. It's a pneumatic replacement to the manual "hammer &\u00a0hole-punch" work that had to be done rigorously.\u00a0The goals were to ease the harsh task on the workers, to save time and reduce the processes cost by eliminating hand tools degradation.\u00a0\u00a0The design exceeded the expectations, and achieved all goals while retaining very low build costs, remarkable simplicity\u00a0\u00a0of handling and operation and a versatile ability\u00a0to repeatedly make clean cut holes in a wide range of positions and diameters.<\/p>\n<\/div>\n

The Challange:<\/p>\n<\/div>\n

Replacing a hammer's strike with a pneumatic actuator is not as straight-forward is one might think. and doing so to perforate 2 layers of thick cargo straps and PVC sheets, is that much harder. I met allot of skeptic opinions along this\u00a0road. a hammer strike concentrates allot of kinetic energy on a very small surface to create incredible amount of pressure at the shearing edge. but the difficult thing to imitate was the speed in which it all happens. Theoretically you could create any pressure you want with the corresponding piston and air pressure.\u00a0but pneumatic\u00a0actuators (even the fastest ones) tends to build-up the pressure rather than giving it all up instantaneously. That tiny interval of time allowed the flexible materials to bend and energy was wasted on forming elastic deformations. The first test involved 410 Kg of force (using an 80 mm piston with\u00a08 Bar)<\/p>\n

and it was not nearly enough to make the double 6 mm holes job. designing or buying an expansive "Impact system" to better mimic the hammer's work was way to costly, I've solved it with creative thinking instead.<\/p>\n\n\t\t
