Description

Door leaf buckle limit stamping forming mould of preapring for an unfavorable turn of events shape

Technical Field

The utility model relates to the field of door leaf punch forming processing, in particular to an anti-deformation door leaf buckle edge punch forming die.

Background

The buckling edge of the door leaf is formed by stamping and molding the buckling edge area of the door leaf by a stamping die. Because the buckle limit of door leaf need be parallel with door leaf edge, the terrace die and the die of current stamping die all set up to the straight type structure of and the buckle limit adaptation of door leaf. However, in the actual processing process, after the door leaf is stamped, because the internal stress of the door leaf plate is released unevenly, the deformation of the part of the plate close to the center of the door leaf is large, and the deformation of the part far away from the center of the door leaf is small, so that the original straight door leaf buckling edge is bent towards one side of the center of the door leaf and is no longer in a straight state, see fig. 4, wherein a is the buckling edge area of the door leaf, B is the embossing area of the door leaf, and C is the area where the buckling edge is deformed. The buckled edge after bending deformation can not meet the production requirement and needs secondary shaping, so that a mold for preventing the buckled edge of the door leaf from deforming is urgently needed to solve the problem.

Detailed Description

The technical solutions of the present invention are further described in detail below with reference to the accompanying drawings, but the scope of the present invention is not limited to the following.

Referring to fig. 1 to 2, an embodiment of the present invention provides an anti-deformation door leaf buckling edge punch forming mold, where the door leaf includes an embossing area and a buckling edge area, and an area of the buckling edge area of the door leaf is smaller than an area of the embossing area. The stamping forming die is suitable for stamping and molding the edge buckling area of the door leaf and comprises an upper die, a lower die, a positioning device for positioning the door leaf and a driving device for driving the stamping die to complete stamping. The positioning device and the driving device both adopt the prior art, and are not described herein.

The upper die is provided with a male die 1, the lower die is provided with a female die 2, the female die 2 is provided with an arc-shaped groove, and the upper end face of the female die 2 is used for placing a door leaf to be processed; the male die 1 is provided with an arc-shaped convex block matched with the female die 2 in size; the arc-shaped direction is opposite to the deformation direction of the door leaf caused by the internal stress after the punching is finished, referring to fig. 3, and the radius R of the inner side surface of the arc-shaped groove is 15626 mm.

Taking an area within 30mm from the side edge of the door leaf as a buckling area; the door leaf is a cold-rolled sheet door leaf, and the thickness of the door leaf is 0.5 mm-0.6 mm.

Referring to fig. 1, during stamping, the door leaf is horizontally placed on the upper end surface of the female die 2 after being fed from the right end of the stamping die, the buckling edge area of the door leaf is located on the left side at the moment, and the embossing area is located on the right side. Positioning the door leaf by using a positioning device of a stamping die so that the edge buckling area of the door leaf is aligned with the male die 1 and the female die 2; and starting the driving device to punch.

Referring to fig. 2, the position D in the figure is a door leaf buckle edge formed by stamping, and the cross section of the buckle edge is in a shape of a Chinese character ji.

After the punching is finished, after the male die 1 is separated from the female die 2, because the internal stress of the cold-rolled sheet is released unevenly, the deformation amount of the part of the sheet close to the center of the door leaf is larger, and the deformation amount of the part far away from the center of the door leaf is smaller, if a traditional straight die is adopted, the buckled edge after the punching is bent towards one side of the center of the door leaf due to the uneven deformation of the door leaf and finally appears in an arc shape, referring to fig. 4, wherein the part A is the buckled edge area of the door leaf, the part B is the embossing area of the door leaf, and the part C is the area where the buckled edge of the door leaf deforms; and this embodiment has adopted reverse circular arc mould, can compensate the bending deformation that takes place to door leaf center one side to the knot limit for the knot limit finally presents the straight state.

The working principle of the utility model is as follows: the stamping die is set to be arc-shaped, the bending direction of the buckling edge of the door leaf is opposite to that of the door leaf, deformation generated by the buckling edge after stamping is finished can be offset, the buckling edge is finally in a straight state, secondary shaping is not needed, and production efficiency is improved.

The foregoing is illustrative of the preferred embodiments of this invention, and it is to be understood that the utility model is not limited to the precise form disclosed herein and that various other combinations, modifications, and environments may be resorted to, falling within the scope of the concept as disclosed herein, either as described above or as apparent to those skilled in the relevant art. And that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the utility model as defined by the appended claims.
