针对现有钢板冲压乙形和笼形保持架的缺点,如结构不理想、加工工艺性差、模具制造困难,材料消耗大和保持架性能低等,本文介绍一新结构─—筒形保持架,基本上克服了乙形和笼形架的缺点,经过几年来的生产考验,筒形架满足了生产的要求。文内介绍了筒形架的设计原理、主要尺寸的确定、原材料板厚的选择、加工工艺性、装配压靠模具等。附图10幅。
In view of the shortcomings of the existing steel stamping B-shaped and cage-shaped cage, such as the structure is not ideal, the processing of poor, mold manufacturing difficulties, material consumption and cage performance is low, this article introduces a new structure ─ ─ cylindrical cage, the basic On the overcome the shortcomings of the B-shaped cage and cage, after several years of production tests, the cartridge to meet the production requirements. The paper introduced the design principle of the cylindrical frame, the main dimensions to determine the choice of raw material thickness, processing technology, assembly and pressing molds.
