At our machining factory Many different processes are carried out, such as the bending and curving of sheet metal, to treat a piece of sheet metal with generatrices and straight edges, exerting an intense force to cause permanent deformation of the sheet, depending on the curvature that you want to give it. . For this type of processes, in our machining workshop we use a press with a die.
In the bending process, the external part of the sheet expands or compresses and this is because the limit of the materials is not the same in tension as in compression. When it is under compression, the materials have a greater elastic limit and a greater plastic deformation occurs on the outside side. This means that the neutral axis is not equidistant from the two surfaces and is located closer to the internal surface than the external surface and the latter gives way sooner because its elastic limit is lower.
What factors intervene?
In a machining factory Various elements intervene in this process, such as the elasticity of the material (which directly influences the recovery of the material and the bending angles must be accentuated), Radius of curvature (It affects the variation in thickness of the decisive shape, as well as in the appearance of cracks or breaks), Direction of the fibers (it depends on the previous laminate to which it has been subjected and the direction in which the fibers are will be very important, to form a greater or lesser quality and durability)
As machining factory What we do is not separate the material we work with, but rather we create a plastic deformation to shape a sheet around a specific angle, to change the shape and achieve the result we are looking for.
Three types of folding:
- Thoroughly folded; It is the option that has greater precision and has a great elastic return of the material.
- Partial bending; It is responsible for compensating the elastic return through the contact of the sheet, with the three tooling points and allows us to correct the depth
- Coined or stamped; To carry out this process, a bender is necessary that can be eight times larger than the previous bender. It allows all springback to be eliminated and precision is the most intense of the three options.
