Abstract

The invention discloses a frame longitudinal beam forming die and process. The frame longitudinal beam forming die comprises a base, a female die, a material supporting plate and a male die, the female die is arranged on the base, a machining area used for containing a frame longitudinal beam material sheet is defined by the upper side face of the female die, and the female die is sunken downwards in the machining area to form a groove; the material supporting plate is movably arranged in the groove in the vertical direction and used for supporting the frame longitudinal beam material sheet upwards; the male die is movably arranged over the groove in the vertical direction so as to have the moving stroke from moving downwards to pressing the frame longitudinal beam material sheet into the groove; and the shape and the size of the upper surface of the material supporting plate and the shape and the size of the lower bottom face of the male die are matched with those of the ventral face of the frame longitudinal beam correspondingly. The frame longitudinal beam material sheet is pressed into the groove through downward movement of the male die, the frame longitudinal beam is directly formed, batch production of the frame longitudinal beam is achieved, the production efficiency is improved, the material supporting plate supports the frame longitudinal beam material sheet, the frame longitudinal beam material sheet slowly descends, the buffering effect is achieved, and the quality problems of springback, warping and the like are solved.

Description

technical field [0001] The invention relates to the technical field of stamping and forming of automobiles, in particular to a forming die and a forming process for a longitudinal beam of a vehicle frame. Background technique [0002] Commercial vehicle frame longitudinal beams are generally made of traditional beam steel 510L. As the market demand for lightweight vehicles continues to grow, commercial vehicle frame longitudinal beams are increasingly made of grades 550L and 550L without reducing the strength of the vehicle frame. QSTE-650 beam steel is a high-strength steel material with a yield strength of 550Mpa, 650Mpa or higher. Due to the large springback problem of high-strength steel, currently high-strength steel frames generally have springback, warping errors, cracking, etc. Quality problems, process control is difficult, resulting in unqualified frame width and leaf spring bracket coaxiality, which have a certain impact on a series of quality problems in the fron...
