AI Technical Summary

Problems solved by technology

It can be seen that the current general relief scheme has no quantitative method for the amount of sidewall relief and concave corner relief in the die surface, and it is only inferred from experience. There are problems such as difficulty in material feeding, material breakage and inability to veneer

Abstract

The invention discloses a method and a device for determining the displacement amount of a mold surface, which avoids secondary processing caused by insufficient processing and reduces the workload of a fitter. The technical solution is: scan the mold after processing; compare the scanned data with the corresponding processing data; statistically analyze the relationship between the fillet radius, side wall inclination and machining residue based on the comparison results; according to the fillet radius, side wall The relationship between the inclination angle and the machining residual amount, combined with the mold surface to formulate the relief amount of the side wall and fillet.

Description

technical field [0001] The invention relates to a technology for determining the displacement of a mold surface, in particular to a method and a device for determining the displacement of a mold surface applied to an automobile outer cover. Background technique [0002] With the development of science and technology and the progress of the times, in the mold design and manufacture, the long-term dependence on the fitter and the fitter-centered manufacturing mode in the past are gradually being replaced by the advanced manufacturing mode centered on technology and design. The debugging problem in the mold manufacturing process is advanced to the processing digital model design, and even the stamping process design stage to solve. Before the mold is processed and manufactured, through various technical processing methods, the processing data adjusted by the mold surface can effectively reduce the possibility of stamping defects. It can be said that the higher the accuracy of t...
