Lubricant supply device, molding apparatus having this lubricant supplying device, and molding method using the lubricant

摘要

Problem to be solved: to provide a lubricant coating apparatus capable of forming a bottom vessel shape body having high dimensional accuracy and excellent smoothness by an impact molding method, a forming apparatus having this lubricant supplying apparatus, and a molding method using the same.Solution: the material carrying means 3 for transporting and molding the molded material 13 to the die cavity 2 of the molding die 1 andA lubricant supplying mechanism for dripping the lubricant 16 only to the central portion of the upper surface of a mounted material, and a lubricant supplying means for controlling the amount of lubricant suppliedA lubricant supply device comprising a die cavity cleaning means provided with an air nozzle for cleaning a die cavity after molding, and a press working apparatus of a bottom vessel shape body equipped with a lubricant supplying devicePress working method.The lubricant supply means can control the flowability of the material to be supplied in the direction opposite to the pressing direction of the punch during impact molding.The relationship between the friction coefficient (. Mu. D) of the die and the coefficient of friction (. Mu. P) of the punch is. Mu.d.gtoreq. 2. Times. P P.Diagram
