Specification for the use and use of lubricating oil in stamping parts processing plants
The stamping parts processing plant needs to apply 20# or 32# oil lubrication evenly on the guiding parts and movable parts of the mold before and after the stamping parts are processed and produced. The stamping parts processing plant needs to apply 20# or 32# oil lubrication evenly on the guiding parts and movable parts of the mold for molds installed under 160 tons of equipment for every 300 pieces. For molds installed on 160 tons of equipment, every production For 100 pieces, it is necessary to apply lubricating oil to the stamping die; when punching 3mm-2mm thin plates, every time 50 pieces are produced, 20# or 32# needs to be evenly applied to the edge of the die or on the sheet. Engine oil; in the process of punching thick plates above 3mm, for every 30 pieces produced, 20# or 32# oil must be evenly applied to the edge of the die or on the plate; the stamping parts processing plant is relatively stable for the process conditions. , Forming and flanging parts. For every 20-30 pieces produced, 20# or 32# oil must be evenly applied to the mold cavity; for the bending, forming, and flanging procedures of thick plates above 3mm, every 20 pieces must be processed. Brush 20# or 32# engine oil evenly on the surface of the die and the surface of the blank; for drawn parts with unstable process conditions and deep-drawn parts, the corners of the die must be rounded for each piece produced , No. 1 special drawing oil is evenly applied to the contact surface between the pressing surface and the sheet, (the specific painting position may be determined by the process state of each part) and the lubrication part should be kept clean. Avoid contact with the surface of the punch or it. Paint on the surface of the blank to prevent the material from sliding along the surface of the punch and becoming thinner. For shallow drawn parts with relatively stable process conditions, the frequency of lubrication should not be less than that of applying No. 1 special drawing oil once every 5 parts; recommended article: What factors are related to the processability of metal stamping products?
