Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
It should be noted that, in the description of the present invention, the terms "first", "second", and the like are used for descriptive purposes only and for distinguishing similar objects, and no order is shown between the two, and no indication or suggestion of relative importance is understood. In addition, in the description of the present invention, "a plurality" means two or more unless otherwise specified.
Referring to fig. 1, the present embodiment discloses a forming positioning mechanism for a sheet material piece, which includes a first profiling supporting unit 3 and a second profiling supporting unit 4 capable of moving towards the sheet material piece along a first direction, wherein the first profiling supporting unit 3 and the second profiling supporting unit 4 are located at two opposite sides of the sheet material piece and can be abutted against the sheet material piece. Wherein, the sheet material spare includes three horizontal part 1 and two vertical parts 2, horizontal part 1 and vertical part 2 end to end in proper order. In the above manner, the first direction may be defined as a top-down direction. Through the setting of above-mentioned first profile modeling supporting unit 3 and second profile modeling supporting unit 4, it is effective right when the panel spare supports, on raising the basis of stress surface, to the required face of panel spare outside injects the metal flow direction simultaneously, can effectively avoid the production of fracture and puckering phenomenon.
In the present embodiment, the first profile support means 3 has a first profile surface 5 provided corresponding to the outer horizontal portion 1, and a second profile surface 6 located at the outer end of the outer horizontal portion 1. The first profiling supporting unit further comprises a third profiling surface 7 which is arranged corresponding to the middle horizontal part 1 and the outer vertical part 2. Wherein preferably said first profile surface 5 and said third profile surface 7 are transitionally connected by an arc. In one of these ways, the first profile support unit 3 comprises a first profile body on which the first profile face 5 is provided and a second profile body on which the second profile face 6 is provided.
In the present embodiment, the second profile-supporting unit 4 can support the sheet material, wherein it is noted that the second profile-supporting unit 4 can abut against the middle horizontal portion 1 before abutting against the outer horizontal portion 1.
With the above arrangement, before stretching, the sheet member has its inside horizontal part 1 and inside vertical part 2 restricted in metal fluidity by the cooperation between the outside contour blocks and the second contour support unit 4; the outer horizontal part 1 is positioned above the inner horizontal part 1; during the stretching process, the first profiling surface 5 can abut against the outer horizontal part 1 and make the outer horizontal part 1 pass over the inner horizontal part 1 and then abut against the second profiling supporting unit 4 along the first direction.
Through the setting mode that above-mentioned outside horizontal part 1 is located the top of inboard horizontal part 1, can be so that tensile in-process, the atress of inboard vertical portion 2 is far less than the outside atress, consequently can effectively reduce the fracture probability of 2 circular arc transitional coupling departments of inboard vertical portion. In a preferred embodiment, the ratio of the distance between the first horizontal part 1 located at the outer side and the middle horizontal part 1 before forming to the distance between the first horizontal part 1 located at the middle horizontal part 1 after forming is between 0.2 and 0.25.
It is noted that there is a gap between the second profiling surface 6 and the outer horizontal portion 1 to enable guiding of the metal flow during the forming of the outer horizontal portion 1 in the first direction. The arrangement mode can effectively avoid wrinkling of the surface of the horizontal part 1 and ensure the forming effectiveness of the outer side horizontal part 1 by extending and limiting the flowing of metal in the stretching process of the outer side horizontal part 1, particularly the horizontal part 1 with a slight radian on the surface.
In the present embodiment, the surfaces of the first profile supporting means 3 and the second profile supporting means 4 are mirror-finished. In the process of abutting the plate piece, by reducing the friction coefficient of the joint surface, the damage to the surface of the plate piece can be effectively reduced, and the service life of the first profiling supporting unit 3 and the second profiling supporting unit 4 can be prolonged.
