Description

Technical Field

[0001] The utility model belongs to the technical field of forming dies, and in particular relates to a side wall drawing die. Background Art

[0002] The side panel 01 is one of the common body outer covering parts, which has the characteristics of large size and complex shape, especially in Figure 1 and Figure 2 In the angular area of ​​the middle triangular window 013 away from the door opening 1a, the height difference between the A surface 011 and the triangular window structural surface 012 changes dramatically. During stretching, the sheet material will gather from the triangular window area to the A surface area, resulting in wrinkle defects at the convex fillet position of the A surface 011 due to excessive accumulation of sheet material, which greatly affects the surface quality of the side outer panel 01.

[0003] In order to improve the surface quality of the side outer panel 01, some manufacturers will form a boss in the area of ​​the lower die corresponding to the triangular window when designing the drawing die, and repeatedly debug and rectify the shape and height of the boss; because the boss and the lower die are integrally formed, the boss can only be increased by surfacing welding, which not only increases the consumption of welding materials, but also increases the debugging and rectification cycle, and has the defects of being time-consuming and labor-intensive. Utility Model Content

[0004] In view of the above shortcomings of the prior art, the purpose of the utility model is to provide a side panel drawing die which is easy to debug and modify, which replaces the traditional one-piece punch with a split punch composed of a punch body and a raised insert, and uses an adjusting gasket to adjust the height of the raised insert, which has the advantages of fast adjustment speed and low adjustment cost; thereby effectively overcoming the deficiency that the boss shape at the triangular window needs to be repeatedly welded to increase the height during the debugging and modification of the one-piece punch.

[0005] To achieve the above-mentioned purpose and other related purposes, the utility model provides a side outer panel drawing die, including a punch and a die; the punch includes a punch body and a raised insert corresponding to the triangular window on the side outer panel; the raised insert is fixed to the punch body by bolts; the die includes a die body and a groove insert; the groove insert is fixed to the die body by bolts, and the groove insert cooperates with the raised insert to increase the molding line length at the triangular window; an adjustment gasket is selectively arranged between the raised insert and the punch body; so that during the debugging and rectification of the mold, the height of the raised insert can be adjusted by using the adjustment gasket to avoid the defects of traditional surfacing welding, such as large consumption of welding materials, long adjustment time and high labor intensity.

[0006] Preferably, the adjustment gaskets have different thicknesses to improve height adjustment accuracy.

[0007] As described above, a side wall drawing die of the utility model has the following beneficial effects:

[0008] The present application replaces the traditional one-piece punch with a split punch consisting of a punch body and a raised insert, and during the debugging and rectification of the raised insert, uses an adjusting gasket to adjust the height of the raised insert to avoid the shortcomings of traditional surfacing welding, such as high strength, slow speed and large welding material consumption, thereby effectively reducing the debugging and rectification cost and cycle of the raised insert; in addition, since the raised insert and the punch body are detachable, it is convenient for the debugging personnel to remove the raised insert for individual profile adjustment, further improving the convenience of profile adjustment of the raised insert.

[0014] Side outer panel 01, door opening 1a, A surface 011, triangular window structural surface 012, triangular window 013, punch 1, punch body 11, raised insert 12, die 2, die body 21, die insert 22. DETAILED DESCRIPTION

[0015] The following is a description of the implementation of the present invention by means of specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0016] See also Figures 1 to 4 It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings in this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no substantial technical significance. Any modification of the structure, change in the proportion relationship, or adjustment of the size should still fall within the scope of the technical content disclosed by the utility model without affecting the effects and purposes that can be achieved by the utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the utility model. The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the utility model without substantially changing the technical content.

[0017] like Figure 1 and Figure 2 As shown, due to the large size and complex profile of the side panel 01, it needs to be processed through multiple processes such as drawing, trimming, and shaping; among which the drawing process is the first process. Due to the drastic height difference between the A surface 011 far away from the door opening 01a and the triangular window structure surface 012, it is very easy to have surface defects on the A surface 011 close to the triangular window 013 during drawing; in order to ensure the quality of the A surface of the side panel 01, a boss corresponding to the triangular window 013 is usually formed on the punch, but the profile and height of the boss directly affect the surface quality of the triangular window structure surface 012. Therefore, during the mold debugging and rectification process, the boss needs to be repeatedly welded to increase the height and the profile is rectified, which has the problems of large consumption of welding materials and time-consuming and labor-intensive.

[0018] Based on this, the utility model provides a new side outer panel mold, such as Figure 3 to Figure 4 As shown, the side outer panel mold includes a punch 1 and a die 2; wherein the punch 1 includes a punch body 11 and a raised insert 12 corresponding to the triangular window 013 on the side outer panel 01; the raised insert 12 is fixed to the punch body 11 by bolts; the die 2 includes a die body 21 and a groove insert 22 that cooperates with the punch insert 12; the groove insert 22 is fixed to the die body 21 by bolts, and an adjustment gasket is selectively arranged between the raised insert 12 and the punch body 11 to change the profile height position of the raised insert 12; it can be understood that the change in height position can be achieved by adding or reducing adjustment gaskets (i.e., the thickness of the adjustment gaskets is uniform, generally 0.1 mm) or replacing adjustment gaskets of different thicknesses (i.e., adjustment gaskets with multiple thickness specifications).

[0019] When it is necessary to debug and rectify the raised insert 12, the profile of the raised insert 12 can be directly processed and modified, and adjustment gaskets of different thicknesses can be set between the raised insert 12 and the punch body 11, so as to debug in turn to obtain raised inserts 12 of different heights and profiles, thereby facilitating the debugging of the raised insert 12 according to the drawing results after debugging, and determining the raised height and raised profile that meet the requirements according to the drawing results after debugging the raised insert 12; since during the entire debugging process, the height adjustment of the raised insert 12 can be achieved by simply adding or subtracting adjustment gaskets or replacing adjustment gaskets of different thicknesses, the deficiency of the traditional one-piece punch that needs to be increased by surfacing welding is effectively avoided, which not only improves the debugging efficiency of the raised insert 12, but also effectively reduces the debugging workload of the raised insert 12.

[0020] Of course, an adjustment gasket may be selectively provided between the die insert 22 and the die body 21 so as to dock with the adjusted convex die insert 12 .

[0021] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
