The invention relates to an automobile spring plate fixing pressing plate and a manufacturing process thereof, and the manufacturing process comprises the following steps: 1, rolling a continuous casting blank into a flat blank by using a box type hole pattern formed by an upper roller and a lower roller through a rough rolling unit; 2, a vertical rolling unit or a flat rolling unit uses a pair of upper and lower rollers or a pair of left and right rollers to form a vertical box-shaped hole to widen the rough rolling incoming material in the horizontal direction, so as to meet the material type size required by entering the finishing rolling unit; 3, a finish rolling unit is adopted, 5-7 two-roller continuous rolling mills are used for conducting precise rolling forming on supplied materials of the finish rolling unit, and a plate base body, a left clamping plate, a right clamping plate, a left clamping table and a right clamping table are formed; and 4, processing a fixing hole in the plate base body. A one-time rolling forming manufacturing process is creatively adopted, the automobile or trailer spring plate fixing pressing plate which is light in weight, high in strength and high in abrasion resistance is produced, the mechanical property of the pressing plate is improved, breakage in the using process is effectively prevented, and compared with a steel casting and a forged part, the manufacturing cost is greatly reduced.

    本发明涉及一种汽车弹簧板固定压板及其制造工艺,其中制造工艺包括如下步骤:1、粗轧机组,利用上、下轧辊构成的箱型孔型将连铸坯轧制成型为扁平坯料;2、立轧机组或平轧机组,利用上、下或左、右一对轧辊构成立式箱型孔对粗轧来料进行水平方向收宽,满足进入精轧机组所需要的的料型尺寸;3、精轧机组,利用5~7架二辊连轧机,对立轧机组来料进行精确轧制成型,形成板基体、左卡板、右卡板、左卡台和右卡台;4、在板基体上加工固定孔。本发明创造性地采用一次轧制成型制造工艺,生产出轻量化、高强度、高耐磨的汽车或挂车弹簧板固定压板,不仅提升了压板的力学性能,有效防止了在使用过程中断裂,而且与铸钢件、锻造件相比,制造成本大幅降低。
