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 aceite y no se usa durante mucho tiempo .
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 superar . En la producción diaria, hay casos en los que el tamaño del golpe es demasiado grande o demasiado pequeño y el tamaño del golpe varía mucho, excepto la matriz convexa y el tamaño de diseño .
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, El tamaño del orificio se volverá más pequeño, la forma del borde del golpe, si el extremo se corta por un chaflán o arco, entonces es poco probable que la fuerza perforadora se deforme debido a la deformación, por lo que el tamaño de la perforación será mayor y el tamaño del golpe será relativamente pequeño, en una práctica de producción específica .
