An embodiment of the present invention provides a method for evaluating the lubricating effect of a lubricant in a stamping process, comprising: coating a variety of lubricants on the sheet to be punched, wherein each lubricant coated sheet to be punched have the same properties; use stamping dies to stamp each sheet to be stamped separately to form multiple target parts; measure the height of multiple target parts to obtain the minimum height value, and the lubricant corresponding to the minimum height value is used as the target lubrication According to the stamping die and the sheet to be stamped, establish a simulation model; set the stamping process parameters of the simulation model; according to the minimum height value, use the simulation model to perform stamping simulation to obtain the friction coefficient of the target lubricant. The invention can quantify the value of the friction coefficient, and the quantified friction coefficient is closer to the real friction coefficient of the lubricant, thereby improving applicability and scientificity, and improving the efficiency and quality of stamping processing.
Description
technical field [0001] The invention relates to the technical field of stamping and forming, in particular to a method for evaluating the lubricating effect of a lubricant in a stamping process. Background technique [0002] In the stamping production process of automobile sheets, many lubricants are used for lubrication, which is beneficial to the forming of parts. At present, there are many kinds of lubricants produced in the market, and different lubricants will have different lubricating effects. The quality of the lubricant's lubricating effect directly affects the production efficiency and production quality. [0003] At present, the way to determine the lubricating effect of lubricants is usually to directly use the friction tester to determine the friction coefficient, but the friction tester is a single pull state, which is very different from the actual production, and the determination result is not accurate. Contents of the invention [0004] In view of this, ...
