technical field

The utility model relates to the technical field of auto parts processing, in particular to a symmetrical flanging shaping mechanism.

Background technique

There are many types of auto parts, especially for auto parts with thin material and high flanging, generally need to adopt rigid extrusion shaping process for processing and production. For example, the high-flange auto parts in Figure 7 are made of cold-rolled steel plates with both sides turned up and formed, and there are multiple arc-welded parts at the final flange position. The requirements for the size and shape of the flange are relatively high. It is necessary to ensure that the surface is smooth and free from bad wrinkling and scratches, and the surface profile tolerance is within ±0.3. The complete strip process diagram can be found in Figure 8.

For the processing and production of the above-mentioned high-flange parts, the traditional rigid extrusion shaping process is adopted. Generally, one side is formed separately, and the other flange is formed after one side is formed. The whole process is not only inefficient, but also Moreover, multiple rigid extrusions are likely to form scratches on the surface of the workpiece, resulting in the production of parts that do not meet the production standards.

The principles and features of the present utility model are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the utility model, and are not used to limit the scope of the utility model.

It should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrated structure. Those of ordinary skill in the art can understand the specific meanings of such terms in this patent according to specific situations.

As shown in Figure 1-Figure 5, the shaping mechanism of the symmetrical flanging of the practical design includes the lower mold base 1 and the upper mold base 2:

The lower mold base 1 is located directly below the upper mold base 2; the lower mold base 1 is equipped with a shaping block 3; 4. A flange forming cavity is formed between the slider seat 4 and the shaping block 3 .

The bottom of the upper mold base 2 is provided with two top pillars 5 respectively located above the two flanging molding cavities, and the bottom end of the top pillar 5 is equipped with a slider 6; when the material belt is loaded on the shaping block 3, The pressing down of the upper mold base 2 can drive the slider 6 to move along the slider base 4 to the flanging forming cavity, so that the material strip is flanged to the shaping block 3 for flanging and shaping.

The symmetrical flanging shaping mechanism designed by the utility model carries the material belt to be processed through the shaping block 3. When the upper mold base 2 is pressed down, it will drive the two sliders 6 to move down synchronously, thereby realizing the material belt Simultaneous flanging operation on both sides, one-time flanging shaping ensures high symmetry of parts flanging, reduces the steps of secondary positioning and forming, and improves processing efficiency.
