摘要
合金工具钢CrWMn冲料模模具整体耐冲击韧性较差,易损坏无法修复。基体采用45号钢,在刃口处堆焊307焊条的冲料模,使冲料模的下料件数从143件提高到587件,下料件单件的成本从14.69元降至5.62元。
shock resistance of blanking die of alloy tool steel CrWMn is poor. It is easily broken and hard to repair. Matrices of alloy tool steel would adapt the steel grade 45 and the blanking die would be overlay welded with 307 welding rod at the cutting edge, thus increasing the amount of blanking pieces of blanking die from 143 to 587, and decreasing the cost of each blanking piece from 14.69 yuan to 5.62 yuan.
