Description
Technical field
The present invention relates to metallic plate punching field, in particular in a kind of adjustment drawn component shape and plate fiber orientation it
Between relative bearing method.
Background technique
It is logical with sheet metals such as steel plate, aluminium alloy plate, magnesium alloy plates in fields such as automobile, rail vehicle and household electrical appliances manufactures
It crosses inner support plate that punching press produces and outer covering piece occupies very big specific gravity.Removing is directly punched shapable plate material parts
Outside, the step for remaining almost all requires draw forming carries out the processes such as deburring, flange, shaping again later.
The product for needing drawing operation for these and shaping occurs stretching insufficient, corrugation class defect in order to prevent, need
In binder surface, bead is set；But for inner support plate, relative to outer plate covering, general shape is complex, needs
Drawing goes out the support construction of certain depth, this has been resulted in, and interior shape drawing depth is big, and complex-shaped stream expects violent position, due to
The setting of bead more easily drawing crack.
These are easy to the workpiece of drawing crack, needing to find Optimized Measures prevents drawing crack, if effect is not so good as people's will, needs
Designer is submitted to change shape in product, this is invisible to increase the production cycle, increases human cost.
Summary of the invention
The purpose of the present invention is to provide a kind of sides for adjusting relative bearing between shape and plate fiber orientation in drawn component
Method solves the above problem of the existing technology.Present invention angle of shape out of plate fiber and product is started with, this optimization
Measure can simply be operated very much by plate shearing machine for blanking, and the cracking that drawing product is effectively reduced may.
Above-mentioned purpose of the invention is achieved through the following technical solutions:
The method for adjusting relative bearing between shape and plate fiber orientation in drawn component, is suitable for vehicle inner panel part die face,
Include the following steps:
Firstly the need of the condition of production before basis, the maximum position of product cracking risk is determined, and its particle is turned to
A bit, referred to herein as breakdown point A；
Determine that stream expects two the most violent directions rewinding line C1, C2, the two general rewinding lines again for breakdown point A
C1, C2 are the two rewinding sidelines nearest apart from breakdown point A；
It is perpendicular relationship by two straight lines B1, B2 of breakdown point A and tangent line D1, D2 of rewinding sideline C1, C2；
Relative to shape in product, the machine direction straight line E to be determined should with two angle θ 1, θ 2 formed by straight line B1, B2
It is roughly equal.
The vehicle inner panel part die face is: main body 1 is connect by fillet 2 with binder surface 3, is arranged outside binder surface 3 and is drawn
Prolong muscle 4, face A5 is located in main body 1 and in the state of being thinned, forming face B6 after the A5 drawing of face, the fillet connected between face A5 and face B6
Region 7 is the maximum position of reduction.
The beneficial effects of the present invention are: the rupture possibility of drawing product cracking risk maximum is reduced, is similar to
" wooden pail effect ", the rupture for being equivalent to cracking point each to product on the whole can be carried out balanced adjustment, improve product
Production stability.It can be effectively reduced the product rejection rate generated by drawing crack, make it that the inner and outer plates such as automobile, household electrical appliances be widely applied
Production field.It is practical.
Detailed description of the invention
The drawings described herein are used to provide a further understanding of the present invention, constitutes part of this application, this hair
Bright illustrative example and its explanation is used to explain the present invention, and is not constituted improper limitations of the present invention.
Fig. 1 is the sectional perspective axis surveys view of drawing inner panel die face of the invention；
Fig. 2 is the partial front topology view of drawing inner panel die face of the invention.
In figure: 1, main body；2, fillet；3, binder surface；4, bead；5, face A；6, face B；7, radius area.
Specific embodiment
Detailed content and its specific embodiment of the invention are further illustrated with reference to the accompanying drawing.
Referring to shown in Fig. 1 and Fig. 2, in adjustment drawn component of the invention between shape and plate fiber orientation relative bearing side
Method will find out shape in the machine direction and product of optimization to solve the problems, such as the generally existing drawing crack of sheet metal drawn component
Match.Its programme element: according to the practical drawing condition of production, the maximum position of risk of rupture is determined, and particle turns to one
Breakdown point A；Two straight line B1, B2 are respectively from breakdown point A, keep it perpendicular with tangent line D1, D2 of rewinding line C1, C2 respectively；It is logical
It crosses the breakdown point and is a straight line E, two angle, θs 1 formed by the straight line and two tangent line D, θ 2 will guarantee identical；Straight line E is just
It is the machine direction that shape matches in product, which comes by adjusting blanking cutter relative to the blanking angle of plate real
It is existing.Main application is: can be effectively reduced the product rejection rate generated by drawing crack, makes it that automobile, household electrical appliances etc. be widely applied
Inner and outer plates production field.
Shown in Figure 1, vehicle inner panel part die face of the invention is made of main body 1 and binder surface 3, main body 1 and binder surface 3
It is connected by fillet 2.The drawn component is to belong to have the case where product on flange, and process complementary surface directly along product sideline, prolong by extrapolation
Stretching can be obtained, and flanged product face and process complementary surface together form binder surface 3, lack to prevent from stretching insufficient and corrugation
It falls into, is provided with bead 4 in certain distance outside the product sideline on binder surface 3.It is suitable for flange surface is without product
The case where, for this workpiece, process complementary surface is fully belonged to from fillet to flange, binder surface after product extension side wall surface, under
Face returns to product piece of the invention.
Face A5 is located in main body 1, has certain drawing depth relative to binder surface 3, in the state of being thinned；Face B6 is in drawing
Preceding belongs to face A5, but drawing process makes it have certain drawing depth relative to face A5, since face A5 has been presented for subtracting
Thin situation, so the radius area connected between face B6 and face A5 7 is caused to become the maximum position of part reduction.
It is shown in Figure 2, according to the practical drawing condition of production, determine the maximum position of risk of rupture, and particle turns to
One breakdown point A；Determine that stream expects that two the most violent rewinding line directions, the two general rewinding sidelines are again for the breakdown point
Two sidelines nearest apart from breakdown point, are determined as C1, C2 here；Two straight line B1, B2 are respectively from breakdown point A, make its difference
It is perpendicular with tangent line D1, D2 of rewinding line C1, C2；Be a straight line E by the breakdown point, the straight line and two tangent line D institutes at
Two angle, θs 1, θ 2 to guarantee it is identical；Straight line E is exactly the machine direction that shape matches in product, which passes through tune
Whole blanking cutter is realized relative to the blanking angle of plate.
The foregoing is merely preferred embodiments of the invention, are not intended to restrict the invention, for the technology of this field
For personnel, the invention may be variously modified and varied.All any modification, equivalent substitution, improvement and etc. made for the present invention,
It should all be included in the protection scope of the present invention.
