Stamping parts quality requirement and control principle
Since stamping toward large-scale and complicated development of stamping parts quality requirements also more and more strict, in order to achieve these goals, stamping parts manufacturers, put forward the related to the quality control principle, embodied in the aspects such as precision, fine and exquisite degrees.
In order to meet the principle of precision stamping parts, deep drawing parts need the number of process calculation to determine through deep drawing technology, because it not only with material nature, deep drawing factors, such as height, number of deep drawing step will involve drawing condition such as diameter, the thickness of the material.
Followed by fine principles about stamping parts, as the number of bending part of the process mainly depends on the shape of the structure complexity, so we need according to the number of the bending Angle and the relative position and bending direction on factors such as comprehensive consideration.
Now that has reached the requirement of precision, fine, nature can not ignore the fine principle, when the section of stamping parts quality and dimensional accuracy is high, can consider to add finishing process after blanking process, or direct the fine blanking process, to obtain the fine stamping parts.
When making simple shape stamping, by a single process of mold can be completed, but in cutting complex shape workpiece, due to the structure of the mould or strength is limited, its inner and outer contour should be divided into several parts blanking, so more metal stamping processing procedures, if necessary you can also choose continuous mode.
In order to ensure the quality of the precision metal stamping parts, improve the stability of the process to increase the number of working procedure is often the case, such as the bending part of the additional orientation process Kong Chong system, increase the deformation in the process of forming reduce Kong Chong lay in deformation zone, can really help to improving the quality of the stampings.
