Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
In the prior art, the edge of the top area of the side wall structure of the vehicle body is wrinkled in the forming process of the side wall structure of the vehicle body due to drawing, flanging and shaping, and the forming of the side wall structure of the vehicle body is seriously affected.
The invention provides a forming method of a side wall structure of a vehicle body, which comprises the steps of drawing and trimming a plate to form a drawing surface; a plurality of gaps are formed in the edge of the drawing surface, corresponding to the top area of the side wall structure of the vehicle body; carrying out flanging and shaping on the drawing surface with the notch to form a shaping surface; and trimming the trimming surface to form the body side surrounding structure, so that at least one part of the notch is reserved at the edge of the top area of the body side surrounding structure.
The following describes the forming method of the vehicle body side surrounding structure in detail with reference to the accompanying drawings.
For convenience of description, the molding process at a-a of the side body structure roof region is described as an example, and fig. 4, 5 and 7 show the shape change of the edge of the a-a cross section in the molding process.
As shown in fig. 4, the forming method of the body side surrounding structure includes drawing a plate material and performing trimming T to trim off an excess plate material to form a drawing surface 1.
As shown in FIG. 5, in the invention, in order to reduce the wrinkling phenomenon of the edge F of the top area of the side body of the vehicle body, a notch G (shown in FIG. 3) is formed on the edge F of the drawing surface 1 corresponding to the top area of the side body structure of the vehicle body, and then the flanging shaping is carried out to form a shaping surface 2. Therefore, in the flanging and shaping process, the gap G can release the internal stress of the material generated in the flanging and shaping process, so that the surface wrinkling phenomenon is effectively improved. Preferably, the number of the notches is multiple, and the notches should be opened as many as possible and larger to avoid the functional surface of the product, so as to release the stress to the maximum extent and maximize the wrinkle absorbing effect.
To further reduce wrinkling of the edge surface during the forming process and improve surface quality, a technical complementary surface 3 is added at the edge F of the roof area of the body side wrap as shown in fig. 5-7. The process supplement surface 3 can create a good stamping condition for the side wall structure of the car body. In the present invention, the complementary surface 3 may be prepared during trimming T after drawing and trimmed off in the final step of forming, for example, in the present invention, the complementary surface 3 may be trimmed off during trimming of the finished surface 2.
A plurality of ribs may be provided on the technical complementary surface 3 to further absorb wrinkles generated during the flanging and shaping processes. Preferably, the process replenishment surface 3 may be provided at a position close to the notch G so that the rib is located in the vicinity of the notch G. The ribs may be implemented in the form of blisters, beads, dimples, etc. as is commonly used in the art. The ribs may include round ribs and square ribs. The ribs can effectively control the feeding resistance, change the internal stress state of the material, adjust the flowing direction of the material and effectively improve the wrinkling defect.
in the forming process of the side wall structure of the automobile body, the edge surface of the side wall structure can rebound under the released stress, and the rebound can influence the size precision of the windshield. Therefore, in the burring process, the step 4 may be formed on the process replenishment face 3 as shown in fig. 6. The height of the step 4 is determined according to the shape and formability of the product. Preferably, the step height is as high as possible to allow the product to stretch more fully, thereby increasing product stiffness to reduce spring back.
preferably, the process complementary face 3 is trimmed off during trimming of the finished face 2 to form the body side enclosure structure, while leaving at least part of the gap G at the edge F of the top area of the body side enclosure structure.
According to the invention, the plurality of notches are formed at the edge of the top area of the side body structure of the automobile body to release the internal stress released in the material forming process, the process supplementing surface is arranged, and the plurality of ribs are arranged on the process supplementing surface and near the notches to control the feeding resistance of the material and adjust the flowing direction of the material, so that the wrinkling defect generated in the forming process can be absorbed to the maximum extent. A step is provided on the process complementary surface to reduce the spring back of the edge surface, further increasing the dimensional accuracy of the windshield.
The invention also provides a body side wall structure which is formed by the forming method and has a notch at the edge of the top area of the body side wall structure, as shown in figure 3.
The invention further provides a vehicle, which is provided with the vehicle body side surrounding structure.
In summary, according to the forming method of the vehicle body side-wall structure, the vehicle body side-wall structure and the vehicle provided by the invention, the forming method of the vehicle body side-wall structure comprises the steps of drawing and trimming a plate to form a drawing surface; a plurality of gaps are formed in the edge of the drawing surface, corresponding to the top area of the side wall structure of the vehicle body; carrying out flanging and shaping on the drawing surface with the notch to form a shaping surface; and trimming the trimming surface to form the body side surrounding structure, so that at least one part of the notch is reserved at the edge of the top area of the body side surrounding structure. The wrinkling that has improved among the prior art automobile body side wall structure because stress is inhomogeneous produces on the edge surface of its top region in stamping forming process from this, prevents that the material is folded and the fracture of edge surface, effectively improves the surface quality of automobile body side wall, reduces the material disability rate in the production to reduction in production cost can prevent simultaneously that the side wall structure from matching the welding spot distortion of welding process and arousing the problem of solder joint fracture, thereby improves the intensity of automobile body.
finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
