Stamping is a production technology that uses the power of conventional or special stamping equipment to directly deform the sheet in the mold and deform it to obtain a certain shape, size and performance of product parts. In the stamping process, due to the different materials used, the working speed of the stamping machine used is different, the tensile coefficient of the workpiece is different, the shape of the workpiece is different, and the subsequent process requirements are different, the stamping oil used will be different. Therefore, when selecting stamping oil, consider the corresponding stamping oil according to the following aspects:
1. The material of the workpiece is different, and the stamping oil used is different. For example, Besrun volatile stamping oil is suitable for stamping lubrication of steel materials. Volatile punching and shearing oil is suitable for punching and shearing, stamping, stretching, calendering and bending of thinner non-ferrous metals and their alloys. It is especially suitable for high-speed punching and copper cutting of aluminum fins in air conditioners and refrigerators. Processing of components. Copper wire drawing emulsified oil is used in the process of large, medium and small drawing of copper wire.
2. Stamping process. Stamping processes include punching, deep drawing, bending, and thinning. Besrun DS-306 volatile stamping oil, high-speed die-cutting for aluminum fins, low taste, no-wash, can also be used for air-conditioning copper pipe bends and tube expansion.
3. What is the tensile coefficient? How many times to deepen? Bethrun easy to clean multi-station aluminum shell drawing oil is specially used for thinning and stretching of aluminum shells and other aluminum products, especially suitable for multi-station stamping and drawing. Stretching equipment. BSR-550 easy-to-clean stainless steel stretching paste can be used directly with a stretching height of about 15CM, using 30 ~ 50% of water with a stretching height of about 10CM, and 50 ~ 80% of water with a stretching height of less than 5CM .
4. The size and speed of the punching machine. Beisirun Easy-Cleaning Iron Drawing Oil is suitable for deep drawing of ferrous metal products, stamping of large pieces, and drawing processing of various parts.
5. What is the problem of the shape of the stamped product to be achieved when the product is drawn deep?
The combination of the above considerations can correctly select the stamping oil, determine the amount of oil to be supplied and the location of the oil.
