Abstract：

Automobile brake block is easy to be damaged,whose general service life is about 3×104～5×104 km.It is an important problem to improve the service life and cut down the costs in manufacturing brake block.The improvement of structure and manufacturing process was done in the aspect of low service life of blanking dies of brake block steel-back.The pre-stressing ferrule was used to improve the structure stressed state.One time wire electrode cutting process was changed into two times manufacturing process.At the same time,the heat treatment hardness was reduced to improve the shock resistance.So the die service life can be increased from several thousands up to 2×105.Good results can be achieved.
