Printer frame structure is simple, not baffle processing complex, but, in mass production. This printer frame screen design, mould, according to the product must be adopted to the structure characteristics of the material, losing materials, bending three working procedure completed. As the product of mass production, need, can be separately from the three sets of working procedure, with three sets of simple mode of production line. Although the process in the processing of between transport increased processing time, but the use of simple mode structure simple, cheap, easy to change applies to, in mass production, and the economic benefit is good. Punching die adopt guide material plate and block material pin positioning, using elastic and unloading plate for unloading, waste can be directly from the concave die down, after a punching parts used in blanking process of processing. Blanking die adopt guide material pin and block material pin positioning, using elastic and unloading plate for unloading, workpiece directly from the concave die a decline. Bending die adopt pins positioning, which can effectively placed the lateral
