The structure of many metal sheet processing machines, including press brakes and shears, is one press brake manufacturers in USA of the aspects one must consider in order to make it work at its best, and to get a high-quality final product.
The structure of these machines must be solid and steady, otherwise they would not bear the stress of sheet processing.
The question that rises is: how do you make the structure of a machine steady and strong? It’s not a simple process, it needs attention and accuracy in every part of the production.
These machines are made starting from the sheets: they are shaped, assembled and then put in a furnace. The direction of the sheet metal is something to carefully consider during this process: the direction of the sheet must be the same in every part of the structure, in order to assure the steadiness required to these machines. As a result, all the components are uniform and have all the same direction. All this is, tough, not enough: the structure is put in a furnace, the heat helps the stability of the parts and lightens the tensions inside the material, making is more stable.
These tactics are the basis that make possible to have a solid and steady structure, but to have a top-of-range product one must not stop here. There are some other tactics that make the structure more durable and functional: machines need to be well anchored to the ground and need to be leveled with great precision. These procedures assure that the machine will keep steady and will bear the stress of the processing.
Something interesting to notice is that nowadays the structures of the machines are lighter, and use less materials, without affecting on quality and functioning. All this is made possible by technology, an important feature of modern machines: electronic controls notice every minimum imprecision and activate devices that regulate the uniformity of the folding process, assuring perfect results.
Namely, there is one particular device that does this job: the crowning system. A set of hydraulic cylinders compensates the natural warping of the ram by lifting the table in its middle section, ensuring continuity and uniformity of folding.
This crowning system is an integral feature of the table: the basis of the table forms a sort of “sandwich”, with the cylinders in the middle. The electronic controller regulates the pressure given to the cylinders, and controls this system with extreme precision.
In order to process sheet metal it’s necessary to know how it reacts and how to handle at best, so that to obtain machinery with the highest standards. We are experts of the field, and this is why our machines are built and designed with particular care and attention.
The raw material processed by our machines is what we work for and what we dedicate ourselves to. Knowing the materials that are going to be processed and that have been processed to produce our machines, knowing how to handle sheet metals, and knowing its characteristics is what enables us to give our customers high quality products.
