Abstract
The invention discloses a primary-sequence forming tool and forming method for omega-shaped elastic strip production. The forming tool comprises an upper die plate and a lower die plate; a left upperdie, a right upper die and a middle upper die are arranged on the upper die plate, upper die rollers are arranged on the left upper die and the right upper die, and a middle upper die roller is arranged on the middle upper die; a left lower die holder, a right lower die holder and a middle lower die are arranged on the lower die plate, a material bearing wheel, a forming roller and a lower die cushion block are arranged on each of the left lower die holder and the right lower die holder, and a middle lower die roller is arranged on the middle lower die. According to the primary-sequence forming tool for an omega-shaped elastic strip, the middle part of the elastic strip is also primarily formed while the two limbs of the elastic strip are formed, and the positioning of the middle part of the elastic strip in the subsequent process is guaranteed; and the operation is simpler, and the positioning is more accurate; and the middle part of the elastic strip is primarily formed in the primary sequence and formed in the subsequent secondary sequence, the purpose of reducing thin-drawing of the middle part and the tail part of the elastic strip can be achieved, and the processing size precision of the omega-shaped elastic strip can be better guaranteed.
