Description

A kind of four sides surrounds box body Bending Mould
Technical field
The utility model belongs to Bending Mould field, specifically, is related to a kind of four sides to surround box body Bending Mould.
Background technology
Bending Mould is a kind of mould for making plate workpiece be bent into preset shape on bender.Bending Mould is various It is various, with the product suitable for various curved shapes, even if the product of same curved shape, its Bending Mould also phase not to the utmost Together, also constantly improved for the mould to many considerations such as bending efficiency, bending quality, same curved shape product It is central.
It is as shown in Figure 1 a kind of semi worked pieces of four sides encirclement box body, Fig. 2 is its upward view, can from Fig. 2 Go out, the right and left of the semi worked pieces is passed through and is bent into semi-surrounding shape, next step need to do is to upper and lower two Edge Bend into the right and left identical structure, with formed four sides surround structure;The folding of the step is carried out using common die The forming accuracy of its corner can not be controlled during curved processing, thus causes product structure to deform big, quality is low;Have in the prior art A kind of following mould, it can solve the above mentioned problem produced by common die.Chinese Patent Application No. 201020153709.2, The publication date patent document on November 10 in 2010, discloses a kind of Double-ear telescopic type bending upper die, on Double-ear telescopic type bending Mould is made up of upper mould body, left and right connector, left and right ears and screw etc., before bending, left and right ears under gravity from By sagging.When upper mould is moved down, because blade outward flange and the upper mould body outward flange of left and right ears maintain an equal level, therefore work can be avoided The obstruction of part left and right sides groove.After the blade of left and right ears contacts workpiece surface, because upper mould body inclined-plane is double to left and right Ear applies the power in oblique 45 ° of directions, and under the component effect of its horizontal direction, left and right ears distinguish outside side shifting, return to Fig. 3 State, the blade for protruding left and right ears is moved in the side grooves of workpiece;After bending process is completed, with upper mould master The upper shifting of body, left and right ears free-falling under gravity, its outward flange returns to fair shape with upper mould body outward flange State, makes bending upper die avoid the obstruction of workpiece groove, is moved back into state before bending.But come from technical scheme disclosed in the patent See, with moving downward for mold, left and right ears gradually broaden, this also implies that the semi worked pieces shown in Fig. 1 are necessary It is put into when mold is in higher position in the ears of left and right, then by semi worked pieces decline synchronous with mold, until contact Lower mould completes bending;The defect of this scheme is obvious, and workpiece is easily given a shock influence positioning accurate in dropping process Spend, workman needs act support workpiece labour intensity big etc..
