Nowadays, in the use of stamping equipment, anti-rust oil and stamping processing oil can be used. If more than half a year, users can use anti-oxidation packaging materials or anti-oxidation oil. The type of specific anti-oxidation oil is easier to clean with lubricants, depending on According to the specifications provided by the manufacturer, stamping parts usually have residual oxidation prevention time after processing, or stamping and cleaning oil will remain on the stamping parts. During this period, the factory will store and repack stamped parts while retaining them. For example, the packaging of automobile stamped parts is box-type packaging, general anti-rust film and other internal anti-oxidation methods, so it can reach an oxidation period of about 1 year , Satisfying transportation requirements or storage, saponified oil is usually used as processing oil and is not used for a long time.
If the user wants to use antioxidant oil, it is recommended to use antioxidant oil. The general characteristics are low viscosity, good compatibility with oil seals, no reaction and certain volatility. The user believes that it is still based on quality, unreasonable blockage or Irregular space is also the cause of stamping materials and deformations, which must be overcome. In daily production, there are cases where the punch size is too large or too small and the punch size varies greatly, except for the convex matrix and the design size.
The machining accuracy and punching space are considered to be solvable. As the cutting edge wears, the tensile stress of the material increases, and the stamping part increases the tendency of material conversion. When the material rotates, the size of the punching hole will decrease , The strong pressure on the material causes plastic deformation of the material, which leads to a larger hole size, when the strong pressure is reduced, the size of the hole will become smaller, the shape of the edge of the punch, if the end is cut by a chamfer or arc, then The piercing force is unlikely to be deformed due to deformation, so the size of the perforation will be larger and the size of the punch will be relatively small, in a specific production practice.
