There are also some shortcomings in comparison between packaging steel strip die and steel die

There are also some shortcomings in comparison between packaging steel strip die and steel die:
　　(1) The production efficiency is lower than that of steel die. During the blanking process, because the parts fall back on the lower die, the parts must be ejected from above, so the production efficiency is not as high as that of the steel punching die. This is due to the poor stability and rigidity of the steel belt, and the belt-carrying die cannot be angled or made into a stepped shape.
　　 (2) Not suitable for punching thin parts. Since the template is made of wood laminate, it will be elastically compressed and deformed under the pressure of the steel belt, thereby increasing the original gap between the convex and concave molds. In order to ensure the quality of the punched parts, parts with a thickness of less than 0.35 mm will not be declared Use conventional and model steel belt die.
　　 (3) It is not suitable for blanking parts that require high precision. As mentioned above, because the elastic compression deformation of the template will change the shape and size of the steel strip, the tolerance of the outer dimension of the part during blanking is about Within 0.4 mm; when blanking and punching, the tolerance of the hole is about 0.12 mm.
