The embodiment of the invention provides a retractor frame, a manufacturing process, a safety belt retractor and an assembling method.The retractor frame comprises a bottom plate, a top plate and two supporting plates, the two supporting plates are spaced and arranged in parallel, and the bottom plate and the top plate are located between the two supporting plates; the two supporting plates are respectively provided with a through hole for installing a braid roller, and the frame is integrally formed by aluminum alloy sections in a punching mode. The retractor frame is formed by the aluminum alloy sections through integral punch forming, the production procedures of an existing retractor frame can be reduced, the quality risk of connection strength when the U-shaped frame and the side plates are connected together through riveting, welding or screws is eliminated, meanwhile, the aluminum alloy materials are adopted, the weight of the frame can be reduced, and light weight of the frame is achieved.
本说明书实施例提供一种卷收器框架、制造工艺、安全带卷收器和装配方法,卷收器框架包括底板、顶板和两个支撑板,两个所述支撑板间隔开且彼此平行设置,所述底板和所述顶板处于两个所述支撑板之间,两个所述支撑板上分别设有安装织带滚筒的通孔,所述框架由铝合金型材一体冲压成型。通过铝合金型材一体冲压成型形成卷收器框架,能够减少现有卷收器框架的生产工序,消除U型框架和侧板之间通过铆接、焊接或螺钉连接在一起时的连接强度的质量风险,同时通过采用铝合金材料,能够降低框架的重量,实现框架的轻量化。
