汽车ABS防抱死齿圈粉末冶金压制模具设计

Pressing Die Design of Powder Metallurgy for the ABS Ring Gear

ABS齿圈是汽车防抱死制动系统的重要零件,如何生产出高精度、高质量的粉末冶金ABS齿圈是一个非常重要的课题。通过对大直径(φ170mm)、多齿(80齿)的粉末冶金ABS齿圈生产工艺过程的分析,从模具的选材、模具结构(多齿分冲,阶梯结构)、模具间隙、模具尺寸等方面,对ABS齿圈压制模具进行优化设计,使压制模具具有高使用寿命,齿圈齿部密度达到图纸要求,后序的镀锌表面也达到了图纸要求。

ABS ring gear is one of the important parts, automotive anti-lock braking system is how to produce high precision, high quality of the powder metallurgy ABS ring gear is a very important topic. This article through to the large diameter （~blT0mm）, toothy （80 teeth） of powder metallurgy ABS ring gear production process analysis, from the die material selection, die structure （tooth points more blunt, ladder structure）, die clearance, die size, etc., optimize the ABS gear ring pressed die design, make the pressing die with high service life and product tooth density in meeting the requirements of the drawings, after the sequence of galvanized surface also meet the requirements of the drawings.
