Description
Technical field
The present invention relates to automobile die field, and in particular to the lower mould of one kind bending.
Background technology
Bending die, bending process be according to part shape the need for, blank is curved by mould and forcing press by certain angle
Degree, the Sheet Metal Forming Technology method of definite shape workpiece.The application of curved super-long structure in the industrial production is quite extensive, on such as automobile
It is many to carry out cover piece and tank bracket component.
The content of the invention
The problem to be solved in the present invention is that providing one kind bends lower mould, improves the efficiency of flat board semi-finished product punching press deformation,
Improve the structural strength of finished product bending part.
To solve the above problems, the present invention provides a kind of bending lower mould, to reach above-mentioned purpose, the present invention solves its technology
The technical scheme that problem is used is：
The lower mould of one kind bending, including：Lower holding pad, possesses the first inclined-plane for being at an angle of connection successively, the second inclined-plane, the 3rd
Inclined-plane, closure of the lower holding pad along the first inclined-plane, the second inclined-plane, the 3rd inclined-plane is in substantially symmetrical about its central axis, central shaft both sides structure
The bending region of bending part is supplied at into two, bending region respectively possesses a long recess and a short groove, long recess connection first
Inclined-plane, the second inclined-plane, the 3rd inclined-plane, short groove are located on the second inclined-plane, and the groove depth of long recess and short groove is constant；Lower cutter block,
By being contacted with lower holding pad and axial symmetry is arranged in the first time cutter block and second time cutter block of both sides and constituted；Positioning tool, is fixed on
Lower holding pad surrounding, possesses the positioning profile matched with the angle of bending part salient angle, fillet.
It is using the beneficial effect of above-mentioned technical proposal：By flat semi-finished product punch forming, main body with the first inclined-plane,
Second inclined-plane, the angle on the 3rd inclined-plane are converted into three sections, while stamp out the muscle identical with long recess, short groove, long recess correspondence
Muscle because being connected to three inclined-planes, improve the angular relationship between three sections of faces after the completion of punching press, short groove is corresponding
Muscle improves the structural strength of the corresponding interlude in the second inclined-plane.
Lower cutter block can stamp out flange, and flange is substantially perpendicular with inclined-plane, and flange is further enhanced after the completion of punching press
Three sections of respective structural strengths of bent plate.Lower cutter block and lower holding pad are non-integral, simplify Making mold difficulty, are easy to split
Combination is repaired.
Positioning tool then plays the precise positioning that bending sheets are treated to tabular, because after bending, finished product is than semi-finished product perpendicular
Reduced during the upward projected outline's size of Nogata.So positioning tool is arranged on the surrounding of lower holding pad, to the half of flat condition
Finished product, which is played, accurately to be positioned, and but the finished product after bending process and bending is not interfered.
As a further improvement on the present invention, dismountable tag block is provided between long recess and adjacent short groove.
It is using the beneficial effect of above-mentioned technical proposal：Tag block is the block of embedded lower holding pad lastblock tape character,
Structure can be stamped out by replacing the tag block with kinds of characters under cutter block under not changing and the structure of lower holding pad
The different finished product of identical but character label, the need for adapting to production marker.
As the further improvement of the present invention, possess middle seam, the central shaft weight of middle seam and lower holding pad on the first inclined-plane
Close.
It is using the beneficial effect of above-mentioned technical proposal：Middle seam plays two pieces of bending parts of prompting and verification, and whether axial symmetry is obtained
Be placed on the effect on lower holding pad, if not axial symmetry, operating personnel by stitched in observation whether between two bending parts gap
Centre just can discover, middle stitch nor affects on the flatness on the first inclined-plane, does not influence bending.
As the further improvement of the present invention, possesses open depression on the 3rd inclined-plane.
It is using the beneficial effect of above-mentioned technical proposal：Due to the non-simple wheel profile of the two pieces of bending parts symmetrically controlled
Shape, it is narrow that the gap between them has width to have, the middle seam in narrow gap on the first inclined-plane of correspondence, and then area is larger in wide gap,
Here provided with open depression on corresponding lower holding pad, opening depression is more recessed than the plane of lower holding pad, and it is not involved in doubling
The bending of comer pieces.Non-working surface on holding pad is depression treatment, while not influenceing operation, essence needed for reducing on holding pad
The area of processing, reduces the manufacturing cost of mould.
As the further improvement of the present invention, positioning profile is in vertically extending, and each bending part is by three positioning tools point
Other three salient angles to bending part are positioned.
It is using the beneficial effect of above-mentioned technical proposal：Positioning tool possesses profile corresponding with bending sheets salient angle is treated, root
The position for treating bending semifinished sheet is limited according to the angle and fillet size for treating bending sheets salient angle, every piece is treated that bending sheets have three
Individual positioning tool is limited, it is sufficient to is limited the free degree for treating bending sheets, is made to treat that bending sheets are in and the lower rational position of holding pad
On.Meanwhile, the vertically extending profile of positioning tool does not influence sheet material to be bent because pressing and bending is moved down.That is positioning tool is limited
The sheet material free degree to be bent, the free degree vertically moving except facing lower holding pad directly.
As the further improvement of the present invention, positioning tool possesses waist-shaped hole, and the length direction of waist-shaped hole points to lower binder
Plate.
It is using the beneficial effect of above-mentioned technical proposal：Waist-shaped hole, can finely tune the position of positioning tool, that is, finely tune relative set
The distance between positioning tool put, optimal orientation distance is gone out to adapt to Field adjustment.
As the further improvement of the present invention, lower holding pad is nested with lower cutter block to be fixed in the intermediate channel of low mold frame,
Intermediate channel is in cross.
It is using the beneficial effect of above-mentioned technical proposal：The intermediate channel of low mold frame is that lower holding pad and lower cutter block provide limit
Position.Criss-cross intermediate channel limit respectively the angular turn peace of lower holding pad and lower cutter block in horizontal plane be moved from by
Degree, accurate positioning.
