Description

Turn to turn-ups mechanism

Technical Field

The application relates to the technical field of vehicle part manufacturing, in particular to a steering flanging mechanism.

Background

With the continuous development of the automobile industry, parts on the automobile body are more and more complex. To accommodate complex exterior styling parts, some long-stroke flanging or shaping styling has to be applied to the inner plate parts. For example, a supporting model is designed on the inner plate to support the outer plate of the luggage case, and the supporting model needs to be realized by flanging and shaping with long stroke, so that the stroke of a movable part in the mold is increased, the mold structure is difficult to realize, the stability of the mold is reduced, and the quality of a product is reduced.

FIG. 1 is a schematic illustration of a prior art interior trunk panel. As shown in fig. 1, a support plate structure 1 is provided on the trunk inner panel. If the supporting modeling of the inner plate of the luggage case is desired, two molding schemes can be adopted in the prior art. The first scheme is as follows: drawing in the first procedure, trimming in the second procedure and the third procedure, and realizing Z-direction straight-upward shaping by using a shaping insert in the fourth procedure. The second scheme is as follows: drawing in the first process, trimming in the second process and the third process, and utilizing a flanging insert to realize the flanging of the support direction wedge in the fourth process. The difference between the two schemes is the fourth procedure, and the Z negative direction straight upward shaping of the fourth procedure in the first scheme can cause the stroke of the lower pressure feeder to be very large and needs a large-stroke nitrogen spring. The long stroke of the material pressing device can cause the instability of the material pressing device, the storage height of the die is ultrahigh, and the price of the large-stroke nitrogen spring is high. Moreover, the shaping height is large, and the shaping insert is in contact with a product before shaping, namely interference is generated, so that shaping cannot be performed. In the second scheme, the fourth process is side flanging in the supporting direction, the distance from the product before flanging to the product after flanging is the same and is very large, the occupied space of the transmission wedge is large, the strength of the lower punch is reduced, and the structure of the transmission wedge cannot meet the requirement.
