Today's cold drawn flat steel is a type of flat steel with high precision, the material used is hardened and tempered, so it can be used directly as a shaft and does not require treatment, thus not only simplifying the process, but also cold drawing flat steel The accuracy of the quality is significantly improved, corresponding to the cold drawn flat steel is actually used to construct ordinary flat steel, the heat treatment conditions of the source are normalized, and the dimensional accuracy, and the material is ordinary, but the cold drawn flat steel The surface is very smooth and the dimensional accuracy is very high.
According to the relevant standards, the standard size of the cold drawn flat steel should be controlled within the corresponding size range, and there are also many materials involved, which have high mechanical properties and can be used directly without processing. Due to their high dimensional accuracy, in order to ensure quality In accordance with the requirements, the same re-cold flat steel and each batch of each steel batch, will be the same diameter inspection, is to put one of each two flat steel.
After the flat steel is cold drawn, there should be no cracks or local pleats on the surface. On the outer surface of the bending test, it is required that the cold drawn flat steel should be free of cracks or cracks after processing, and only use cold drawn flat steel conforming to the standard quality. Can be widely used in hardware tools and automotive standard parts, therefore, in the production of cold drawn flat steel, the choice of materials should be a reasonable requirement, then cold drawn flat steel is formed by advanced processing.
At present, the product can meet the requirements of practical application. If the flat steel edge of the cold drawn flat steel is inwardly rolled, it can be leveled according to the method of leveling the flat steel. If the cold drawn flat steel is twisted to the outside, it should be placed in a triangular shape. Concave tires or flattened when cold, in the curved part, because cold drawn flat steel can adapt to harsh working conditions, but also have their own quality and performance requirements, if these basic conditions are not met, it is likely to have performance problems during use. .
