The supporting leg is a square tube, a contraction opening is machined in the lower portion of the square tube and used for being connected with a rotating shaft, the forming device of the supporting leg comprises a first punch forming device and a second punch forming device, the first punch forming device positions the supporting leg through a first inner mold, and the second punch forming device positions the supporting leg through a second inner mold. Four wrap angles of a square tube of the supporting leg are stamped into long grooves and transition fillets through a first inclined stamping die, and the two side faces of the supporting leg are formed through the second stamping forming device through the interaction of a second horizontal stamping die and a second inner die. According to the device, through two-time punch forming, closing-up of the lower portion of the supporting leg is achieved, the forming precision is high, welding is convenient, cost is saved, a quantitative production process is provided for batch production of the supporting leg, and the formed closing-up position is consistent in specification and attractive in appearance.
一种支腿支脚及成型装置,支脚为正方形的方管,在方管的下部加工收缩口用于与转轴连接,一种支腿支脚的成型装置包括第一冲压成型装置和第二冲压成型装置,第一冲压成型装置通过第一内模将支腿定位,利用第一斜冲模将支脚方管的四个包角冲压成长槽及过渡圆角,第二冲压成型装置通过第二水平冲模与第二内模的相互作用,将支脚两侧面成型。该装置通过两次冲压成型,实现支脚下部收口,成型精度高,焊接方便,成本节约,为支脚的批量化生产提供一种量化生产流程,成型后收口处规格一致,外形美观。
