Pivatic double punching technology was a product of developing the mechanical structure of the tool cassette technology and cycle time of the punching line. The 625 mm reach of a tool cassette jaw was suitable for narrow blanks or coils, but if the coil width exceeded the reach, one tool cassette would not be enough. As a solution, a second tool cassette with its own tool selector was added to the other side of the blank or coil. The selectors of both tool cassettes use the same punch plate, so symmetrical holes in the product can be double punched, i.e. punched at the same time – something that is not possible using traditional turret punch press technology. Our customers get the best benefit from Pivatic’s double punching technology when it comes to families of products, and production batches ranging from a few pieces to several thousand pieces.
There are different types of tool cassettes, and the cassette type and tools are selected according to the customer’s needs. “Thick Turret, Amada-Style” tool sizes A, B, C, D, E and F are suitable for tool cassettes. With standard settings, 16 – 26 tools can fit in one cassette, but with multitool adapters the number of tools can be increased to more than 50 tools per cassette, i.e. more than 100 tools per punching station with two cassettes. In addition to piercing tools, tool positions can also use form pressing tools or cluster tools that pierce an entire hole pattern at once.
Ultimately, the double punching technology allows you to increase your production efficiency to up to double the speed, while maintaining the highest quality.
