Embodiment Construction

[0036] The molding method is as follows:

[0037] Technical scheme process step of the present invention is as follows:

[0038] The first step: Blanking

[0039] Computes the expanded length from a linear expansion.

[0040] Step 2: First Forming Bending

[0041] The dimensional relationship of each part of the workpiece after the first molding: such as Figure 2.2 shown

[0042] α = Ф (required diameter of parts) - 1 unit mm

[0043] R1 is α / 4 rounded unit mm,

[0044] H=5 unit mm

[0045] L is greater than 1 / 4 unit mm of the perimeter length of the finished product, and less than or equal to 1 / 2 unit mm of the expanded length of the finished product

[0046] Adjust the shape of the perimeter of the finished product by adjusting the size of H to make it meet the size requirements of the drawing. The above parameters are obtained through many tests and calculations, and have been solidified into standard documents.

[0047] Step 3: The circle is formed as shown in th...

Abstract

The invention discloses a method for forming rolled components of automobiles. The method includes that two punch forming procedures are carried out on a rolled component by the aid of two dies, a primary forming bending procedure is carried out on the rolled component by the aid of the second die, a U-shaped body is formed after the primary forming bending procedure, two vertical plates are arranged on two sides of the U-shaped body, a repeatedly bent cambered surface is arranged at the bottom of the U-shaped body, arcs of outward lower protrusions are arranged at two ends of the bottom of the U-shaped body, and an upward internal protrusion is arranged in the middle of the bottom of the U-shaped body; the rolled component is punched by the second die to form a circle. Compared with the traditional method, the method for machining the rolled components of the automobiles has the advantages that working procedures can be reduced, the machining efficiency can be improved, the machining speed is fast, the dies are simple in structure, and finished products machined by the method are high in precision.

Description

technical field [0001] The invention is applicable to the rolling forming method of metal sheet metal parts in the machinery industry, and particularly relates to a forming method of rolling parts in the automobile industry Background technique [0002] In automotive parts, especially automotive shock absorber parts, many tubular parts are often encountered. Due to the application, the diameter and precision of these parts are non-standard, and there is no corresponding profile on the market. In addition, its shape, dimensional accuracy, and even its material thickness requirements are very strict, which poses a difficult problem for us, how to form a sheet metal mold into a tube-shaped part? [0003] The traditional rolling method mostly adopts the processing method, which has many procedures, low efficiency, cumbersome adjustments, cannot meet the requirements of stricter dimensional tolerances, and the appearance of indentation deformation is obvious. Contents of the i...
