What is a stamping die? The stamping die relies on the stamping machine and abrasive tools to release the external force on the plates, strips, pipes and aluminum materials, so as to cause plastic deformation or separation, and then obtain the shape and specifications of steel parts (stamping parts) forming production Processing methods. Stamping die and forging are both plastic deformation production and processing (or working pressure production and processing), collectively called forging. The key to the blank of the stamping die is the thick steel plate and steel chain that are hot-rolled and cold-rolled. Among the steel talents in the world, 60 to 70% are plate talents, and most of them are made into finished products through stamping dies. Car body, car chassis, car fuel tank, radiator fins, steam drums for industrial boilers, housings for utensils, electric motors, transformer iron core ferrite cores for household appliances, etc. are all processed by stamping parts. There are also many stamped parts in instruments, electrical appliances, bicycles, enterprise office machinery and equipment, clothing, food, housing and transportation containers.
Nowadays, in the application of stamping machine tools, rust inhibitors and stamping parts processing oils can be used. If it exceeds more than half a year, customers can apply antioxidant packaging products or antioxidant oils. The type of special antioxidant oils is easier. Cleaning with lubricating fluid is due to the index value shown by the manufacturer. The stamping parts generally have residual air oxidation avoidance time after production and processing, or the stamping die and cleaning oil will be stored on the stamping parts.
During this time, the processing plant will store and repack the stamped parts, and save them. For example, the packaging of automobile stamping parts is box-type packaging, generally anti-rust treatment plastic film and other internal oxidation resistance methods, so it can do By the air oxidation period of about 1 year, considering transportation regulations or storage, saponified oil is generally used to produce processing oil and is not used for a long time.
The precision of production and processing and the interior space of the stamping die are considered to be manageable at the following levels. With the damage of the drilling edge, the tensile stress of the raw material increases, and the stamping parts enhance the development trend of raw material changes. When the raw material rotates, The specifications of the punching machine will be reduced, and the strong working pressure on the raw material will cause the plastic deformation of the raw material, which will result in a larger hole breaking specification. When the strong working pressure is reduced, the hole breaking specification will shrink. The beam end is cut by a slope or arc laser, and the penetration force is unlikely to be caused by the deformation. Therefore, the specifications of the hole will be larger, and the specifications of the punching needle will be relatively small, in special life practices.
Because the appearance, specifications and precision regulations of stamping parts are different, there are various ways of cold die production and processing. According to the deformation characteristics of the raw materials and the habit of the company's current standards, the basic process flow of the cold die can be divided into two types: separated process flow and plastic deformation process flow.
People say that stamping parts generally refer to cold die parts. For example, a stainless steel plate, if you want to turn it into a fast food plate, you have to design a set of abrasive tools first. The digging working surface of the abrasive tools means What the dish looks like, pressing this stainless steel plate with an abrasive tool will become the dish you want. This is called cold stamping, which means immediately using a grinding tool to start stamping molds for hardware materials.
