Let’s talk about the classification of sheet metal bending process first. sheet metal parts choose different cutting methods according to different requirements, including Laser Cutting, CNC plasma cutting, sheet metal cutting and other different methods. Generally, in order to consider the cost of large-scale sheet metal processing, shears and machine cutting are often used. However, CNC Laser Cutting machines are generally used to ensure some precision requirements and processing capabilities.
sheet metal processing is simply a machining technology, that is, the process of using the plasticity of materials to process them into various parts. So there is the term Sheet metal processing and manufacturing technology. So, do we all know its type? I think the answer is no, then, in response to this question, let's discuss it in detail and let us know some of its main types, so that we can better understand and further process this product with sheet metal. Sheet metal processing and manufacturing technology, its main types are:
(1) Plastic forming technology can be divided into three types: fine-grain plasticity, phase transformation plasticity and other plasticity. Among them, it is widely used, but there are certain requirements, mainly that the equiaxed fine-grained structure should have good thermal stability, the deformation temperature should be higher than the melting point of the material, and the strain rate should be low.
(2) Laser shock technology, that is, the laser beam impacts the metal surface in the form of pulses, thereby forming a plane wave, which can cause plastic deformation of the material.
(3) Hydroforming technology, that is, a hydraulic bag is used as an elastic female or male mold, and oil is used as a pressure transmission medium, thereby performing forming operations and processes.
