剪刀刃口成型传统工艺是在其刃口处采用锻工嵌钢,然后进行热压成型。模具材料为3Cr2W8V钢,模具寿命为模压16000件。现在剪刀刃口成型改用堆焊刃口钢,并利用其堆焊余热直接模压成型的先进工艺,使产品的产量与质量得到提高,减少了能耗,生产成本显著降低。然而,剪刀坯在堆焊刃口钢后的余热温 Scissors cutting edge forming the traditional process is used in its cutting edge forging steel, and then hot-forming. Mold material is 3Cr2W8V steel, mold life is molded 16000 pieces. Cutting edge is now used instead of cutting edge welding surfacing edge steel, and the use of welding heat directly surfacing molding advanced technology, the product yield and quality has been improved, reducing energy consumption, significantly reducing production costs. However, the scissors blanks after surfacing the edge of the steel afterheat temperature
