Abstract

The utility model relates to a bending die for sectional materials used in automobile windows, which comprises a combined wheel die (1) of hollow I-shaped section, a grip die (2) of a sagging structure, an anti-creasing die (3) and a slider die (4). The utility model can solve two problems encountered during the once bending and forming of sectional materials for automobile windows: first, crumpling up of in-folding edge in the bent section caused by compressive force; secondly, the deformation of out-folding edge in the bent section caused by drawing force. When bending sectional materials with the bending die, both the in-folding edge and the out-folding edge are all contained in the die cavity to prevent crumpling up of the in-folding edge caused by compressive force and deformation of out-folding edge caused by drawing force. Therefore sectional materials can be formed at once, with simplified process. Besides, the utility model helps reduce cost and improve the integrity and beauty of sectional materials for automobile windows.

The specific embodiment

Referring to Fig. 7,8, among the figure vehicle window frame of certain automobile and the section bar 5 of this vehicle window frame, described section bar 5 is made of the interior flanging 5-2 and the outer flanging 5-3 of substrate 5-1, substrate, and this mould designs for crooked this section bar.

Referring to Fig. 1, this mould is made up of wheel mould 1, clamping die 2, wrinkle resistant mould 3 and slide plate mould 4;

Referring to Fig. 6, the described mould 1 of taking turns is to be the I-shaped combination die of hollow by the cross section that base mold 1-1 and top cover mould 1-2 constitute, and top cover mould 1-2 is bound up on the base mold 1-1 by helicitic texture, is provided with the half groove 1-12 that can stretch into flanging 5-2 in the section bar on base mold 1-1 and end face that top cover mould 1-2 contacts;

Referring to Fig. 1,2, described clamping die 2 is made up of half indent channel mould 2-1 and outer raised line mould 2-2 of a default concave edge, referring to Fig. 9, described half indent channel mould 2-1 inlays on the base mold 1-1 that is installed in the wheel mould according to its inner concave 2-11 and the tangent line vertical plane 1-11 that takes turns beam barrel in the mould with the position of vertical plane, and be connected with each other by oat tail groove structure 2-12, referring to Fig. 3, the default concave edge of this half indent channel mould 2-1 is facing to the described top cover mould 1-2 that takes turns mould, make the afterbody of this half indent channel mould complete inner cavity 6 that cooperates with outer raised line mould 2-2 of gland formation, on the end face of the default concave edge of this half indent channel mould, also be provided with half a groove 2-12 that can stretch into flanging 5-2 in the section bar because of the top cover mould.The cross section of described outer raised line mould 2-2 is the shape of middle part evagination, after this outer raised line mould and half indent channel mould fasten, forms the die cavity (as shown in Figure 2) of section bar 5 between their concaveconvex structure.

Referring to Fig. 4,5, described wrinkle resistant mould 3 is made of half indent channel mould 3-1 and a cover plate mould 3-2 who covers on the default concave edge of this half indent channel mould 3-1 of a default concave edge, and described half indent channel mould 3-1 is identical with half indent channel mould 2-1 structure of clamping die among Fig. 2.

Referring to Fig. 9, the front end of described half indent channel mould 3-1 and cover plate mould 3-2 is provided with and takes turns the concave arc structure that mould 1 periphery coincide, they dock with wheel mould 1 by this concave arc structure, and be installed on the crooked frame with the position of vertical plane according to its inner concave 3-11 and the tangent line vertical plane 1-11 that takes turns beam barrel in the mould, it is fixed; Described slide plate mould 4 is identical with the outer raised line mould 2-2 structure of clamping among Fig. 2, and behind this slide plate mould 4 and wrinkle resistant mould 3 fastenings, forms the die cavity (as shown in Figure 4) of section bar 5 between their concaveconvex structure.

Referring to Fig. 9, before the bending, the manipulation bending machine will be taken turns mould top cover mould 1-2 and be unscrewed, wrinkle resistant cover plate mould 3-2 pine is pressed from both sides, to clamp outer raised line mould 2-2 and slide plate mould 4 pine folders simultaneously, then section bar 5 is installed in the die cavity, again top cover mould 1-2 is screwed, wrinkle resistant cover plate mould 3-2, the outer raised line mould 2-2 of clamping, slide plate mould 3 are clamped respectively, need before the clamping of its middle slide plate mould to regulate its upper-lower position, its outer male structure can be slided in the cavity of wrinkle resistant mould.

Referring to Figure 10, when crooked, handle bending machine according to direction of arrow moving runner mould 1 among the figure, simultaneously, promote slide plate mould 4 and escort section bar 5 reaches, the angle that wheel mould 1 is rotated promptly is an angle of wanting crooked, sets the bending that the angle of rotating can be finished section bar 5.

By said structure as can be seen, this mould is being carried out when crooked, and the interior flanging of section bar 5 and outer flanging all are limited in the die cavity fully, the caused workpiece deformation thereby the wrinkling and outer flanging that prevents the edge break limit effectively stretches.
