Problems solved by technology

[0003] The current torsion beam can be formed by stamping a pipe. When stamping, the interior of the pipe is a cavity, and there is no support structure. However, the cavity in the middle of the torsion beam is small, and the deformation required to occur in the middle of the pipe is large. The stamping speed is fast and easy. Crack the pipe in the middle, resulting in a reduction in the strength of the torsion beam

Embodiment 1

[0038] Regulates methods of manufacturing stamped and formed high-strength torsion beams, such as Image 6 As shown, the torsion beam is formed by stamping the pipe material 6, and four retaining rods coaxial with the pipe material 6 are inserted into the inner cavity of the pipe material 6 used to manufacture the high-strength torsion beam. The annular elastic sleeve 71 on the 7 and some support rods 72 between the elastic sleeve 71 and the central rod 7, the central rod 7 and the elastic sleeve 71 in this embodiment are all longer than the pipe 6, and the left end of the central rod 7 is a handle The holding end, when the central rod 7 is located in the pipe 6, the holding end is located outside the pipe 6. The elastic sleeve 71 is made of NBR, and the surface of the elastic sleeve 71 is smooth. The two ends of the support rod 72 are respectively hinged on the central rod 7 and the elastic sleeve 71 .

[0039] And when the center rod 7 is manually pushed to the right relati...

Embodiment 2

[0047] like Figure 8 As shown, on the basis of Embodiment 1, the right end of the elastic sleeve 71 in this embodiment is closed to prevent paraffin from entering the elastic sleeve 71 from the right end of the elastic sleeve 71, so when the elastic sleeve 71 slides in from the left end of the pipe material 6 from The right end of the pipe 6 feeds molten paraffin into the pipe 6 to improve work efficiency. In practice, in addition to the paraffin, the pipe 6 can also be filled with molding sand, steel shot with a diameter less than or equal to 1mm, or a combination of molding sand, steel shot and paraffin. Other than that, other operation steps in this embodiment are the same as those in Embodiment 1.

Abstract

The invention relates to the field of automobile accessories, and particularly discloses a high strength torsion beam for pipe punch forming. The high strength torsion beam comprises a main body, themain body is internally provided with a closed cavity, the main body is formed by a pipe through punching, and the pipe is filled with paraffin; the main body sequentially comprises a left end section, a left transition section, a middle section, a right transition section and a right end section in the axial direction, the outer diameter of the middle section is smaller than the outer diameters of the left end section and the right end section, the cross section of the middle section in the vertical direction is in a V shape, the cross sections of the left transition section and the right transition section in the vertical direction are concave, and the cross sections of the left end section and the right end section in the vertical direction are in opening shapes. The torsion beam in thescheme can support the side wall of the pipe when the pipe is punched.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a method for manufacturing a high-strength torsion beam formed by control stamping. Background technique [0002] The torsion beam suspension is a type of rear suspension of the car. The wheels of the car are installed at both ends of the torsion beam. The torsion beam can balance the up and down jump of the left and right wheels to reduce the shaking of the vehicle and keep the vehicle stable. The torsion beam has a simple structure and a large bearing capacity, and is generally used for trucks, ordinary passenger cars and some special vehicles. [0003] The current torsion beam can be formed by stamping a pipe. When stamping, the interior of the pipe is a cavity, and there is no support structure. However, the cavity in the middle of the torsion beam is small, and the deformation required to occur in the middle of the pipe is large. The stamping speed is fast and easy. Cracks occurre...
