一、最佳套切复合模具的特点保持器使用单模下料时,一般钢材利用率仅15～17％。最佳套切复合模具就是通过轴承的各种规格尺寸经统一计算和排列,用以求得保持器的最佳套切数据,即:使切除余量为最小、或使各毛坯之间切除余量等于零的一种模具。我厂设计了单列向心球轴承型号为305、306双切复合模具和轴承型号为208、207、206多切复合模具,均已用于生产。采用最佳套切复合模具,钢材利用率由原来单切下料时的30％提高到46％。这种模具并附有自行退料机构,使用方便。
First, the characteristics of the best sets of composite die Setter when using single-mode unloading, the general utilization of steel is only 15 to 17%. The best sets of composite die is through the bearing size and size of a unified calculation and arrangement, in order to obtain the best holder sets the data sets, namely: the allowance for the removal of the smallest, or between the rough cut more than A quantity equal to zero a mold. I plant a single row of radial ball bearings designed to 305,306 double-cutting composite molds and bearing models 208,207,206 multi-cutting compound mold, have been used in the production. Using the best die-cutting compound mold, the utilization rate of steel increased from 30% when the original single cut to 46%. This mold with its own back-off agencies, easy to use.
