我厂生产的板式液压千斤顶系列产品,其特点是板金件较多,因而生产中使用的落料、压延和复合模具也较多。板金件中又以厚度为6～8mm的碳素钢板占多数,故在大批量生产中,模具的消耗量很大。所以提高模具质量,延长使用寿命,是摆在我们面前一个紧迫的课题。为此,我们以其中较复杂的三角臂零件整体落料模为攻关对象,从冷热加工等多方面对制造工艺加以改进,并严格按改进后的工艺制造模具,从而杜绝了在模具制造过程中产生废品,并成倍延长了使用寿命。至今已冲压零件7万多件,模具仍完好无损,获得了良好的综合经济效益。
I plant plate hydraulic jack products, which are characterized by more pieces of sheet metal, which used in the production of blanking, rolling and composite molds are more. Sheet metal in order to the thickness of 6 ~ 8mm carbon steel accounted for the majority, so in high volume production, mold consumption is large. Therefore, improving the quality of the mold and prolonging the service life is an urgent issue before us. To this end, we have more complex parts of the Triangle arm blanking the overall target for the object, from hot and cold processing and other aspects of the manufacturing process to be improved, and strictly in accordance with the improved process of manufacturing molds, thereby eliminating the mold manufacturing process In the waste generated, and doubled the service life. So far stamping parts more than 70,000 pieces, the mold is still intact, access to a good comprehensive economic benefits.
