我厂使用株州601厂生产的GT35钢结硬质合金制造电机铁芯片冲裁模具,比原来用Cr12高碳高铬模具钢制造模具提高寿命,降低成本。现把GT35钢结硬质合金制造模具应该注意的加工工艺作如下简介。一、锻造开始阶段由于对GT35钢结硬质合金自由锻造规律没有掌握,锻坏了不少材料,经过实践,认识,再实践,再认识的过程。由不会锻到多火锻成,由多火锻成到少火锻成。
Our factory uses the GT35 steel knot cemented carbide made by Zhuzhou 601 Factory to manufacture the motor iron core blanking die, which increases the life span and reduces the cost compared with the original die made of Cr12 high carbon and high chromium die steel. Now GT35 steel bonded carbide manufacturing mold should pay attention to the processing technology as follows. First, forging the beginning of the stage due to the GT35 cemented carbide free forging rule is not mastered, forging a lot of material, through practice, understanding, re-practice and re-understanding of the process. Will not be forged to a multi-fire forging, forging more fire forging into less fire.
