Description

Diel

Technical field

The present invention relates to metallic plate punching field shaping technique, and in particular to a kind of diel.

Background technology

Various parts are assembled into target product by being connected with each other in product.In view of the requirement of function and shape, product Part is also very common using the situation of sheet material, and some parts are from sheet material and require possess specific shape, as lath-shaped produces There is appropriate angle, this Product processing is very difficult between each adjacent area of product.It is as shown in fig. 7, to be formed in figure There are tetra- regions of A, B, C, D, the plate face of a-quadrant and the plate face of B area to form angle formula cloth by boundary of ab boundary lines on blank plate 1 Put, there is the similar relation between A and B between B and C, C and D.The plate face in two regions is merely pressed into specific folder Angle is not difficult, it is difficult to when A and B peripheral profile is the irregular edge of not rounded, non-side, how to determine boundary line Position is simultaneously fixed.

The content of the invention

It is an object of the invention to provide a kind of diel, the diel is easy to processing plate material parts to have irregular week There is angle requirement between edge profile and each region portion of part.

To achieve the above object, present invention employs following technical scheme：A kind of diel, including upper die and lower die, The forming surface of upper die and lower die is the angle formula type face to cooperate, the angle of the forming surface and the folder of product bending place to be formed Angle is consistent, and first and second two positioning units is provided with lower mould, the spacing median plane of first and second positioning unit on lower mould with pressing from both sides Bending part Central Symmetry face between first and second forming surface of angle arrangement overlaps, and the spacing between first and second positioning unit is more than The distance between both ends of kink of product to be formed, first and second positioning unit limit the kink center of product to be formed The plane of symmetry moves up and down along spacing median plane.

In such scheme, by the punching press of the angle formula forming surface on upper and lower mould, by the adjacent of sheet material blank to be formed Drape forming is the angle formula bending side shape for meeting design requirement, and main points of the invention are exactly to be that the accurate of bending part is determined Position, and the displacement of bending part is used restraint limitation exactly in punching course.The present invention is for complicated peripheral profile And the Product processing of multiple bending parts provides extremely convenient shaping scheme.

Embodiment

With reference to Fig. 7,8, there is provided the plane setting-out blank plate of product 1 to be formed, have tetra- plate face areas of A, B, C, D on blank plate Domain needs to implement angle formula bending process by design requirement.Operated in order to facilitate punch forming, it is pre- on the edge of blank plate Stopper protrusion 50 has been stayed, stopper protrusion 50 is centrally located on the kink Central Symmetry face of blank plate, in other words, limit convex The line of centres in portion 50 overlaps with the kink Central Symmetry face of blank plate, so-called kink Central Symmetry face it also will be understood that For the equidistant point of two plate faces of A, B.The present invention is exactly to try to determine blank plate in turn by the positioning to stopper protrusion 50 Bending part.

Below in conjunction with the concrete scheme of brief description of the drawings mould.

With reference to Fig. 1,6, diel, including upper mould 10 and lower mould 20, the forming surface of upper mould 10 and lower mould 20 is phase interworking The angle formula type face of conjunction, the angle of the forming surface are consistent with the angle of the bending place of product 1 to be formed, and is provided with lower mould 20 First, 2 two positioning units 30,40, the spacing median plane of first and second positioning unit 30,40 and the of angle arrangement on lower mould 20 First, the bending part Central Symmetry face between two forming surfaces 21,22 overlaps, and the spacing between first and second positioning unit 30,40 is more than The distance between both ends of kink of product to be formed, first and second positioning unit 30,40 limit the kink of product to be formed Central Symmetry face moves up and down along spacing median plane.

As shown in drawings, described lower mould 20 is V-type cavity plate to the preferred scheme of the present invention, and upper mould 10 is V-type punch-pin, first Positioning unit 30 includes first and second two pieces of locating pieces 31,32, on first and second locating piece 31,32 toward each other, arranged adjacent Area of space between first and second facade 311,321 forms limition orientation passage.Stopper protrusion 50 is located at first and second facade 311st, it is subject to spacing between 321 and by it, can be moved up and down in the guide channel between first and second facade 311,321, to The process of lower movement is accompanied by matched moulds process and carried out.After mould separates, by stopper protrusion 50 together with product to be formed Blank plate 1 move up the bending that can carry out next position or formed product process terminates.

It should be noted that by lower mould 20 is designed as V-type punch-pin, upper mould 10 is designed as V-type cavity plate is also feasible.In order to Convenient processing, it is more convenient that the blank plate 1 of product to be formed is traditionally placed on implementation processing on lower mould.

Described lower mould 20 is V-type cavity plate, and upper mould 10 is V-type punch-pin, the second positioning unit 40 and the first positioning unit 30 Part form it is identical with part construction.It can be arranged symmetrically using this scheme, while the processing of convenient lower mould 20 and the First, the processing of two locating pieces 31,32, i.e., first and second same locating piece 31,32 can reduce the processing capacity of part.

The lower half block for forming first and second two pieces of locating pieces 31,32 of the first positioning unit 30 is inserted on lower mould 20 In the mounting hole 23 opened up, the hole wall of mounting hole 23 includes first and second hole wall 231,232 of closing in groove profile, first and second hole wall 231st, 232 and first and second two pieces of locating pieces 31,32 on cylindrical guides 312,322 coordinate.Form the first positioning unit 30 Very simple when first and second two pieces of locating pieces 31,32 assemble with mounting hole 23, i.e., first and second two pieces of locating pieces 31,32 are planted It can be formed in mounting hole 23 and implement constraint positioning to the stopper protrusion 50 on blank plate, while ensure that it is moved freely up and down. Additionally once, after first and second two pieces of locating pieces 31,32 plant mounting hole 23, the height upwardly extended should be with lower mould 20 On first and second forming surface 21, the table top of blank plate 1 of placement product to be formed of 22 edges coincide, before guarantee starts compacting The blank plate 1 for treating shaped article imposes positioning.

With reference to Fig. 5 b, raised line 323 is set in the outer side edges of the second described facade 321.The setting of raised line 323 plays constraint limit The effect of position convex portion 50, prevents it from being moved along ab boundary lines direction.

The core content of the present invention is to reserve lower limit convex portion 50 on the edge of blank plate, set on lower mould 20 Corresponding positioning unit is implemented to constrain to stopper protrusion 50, and the a-quadrant of blank plate and the relative position of B area are closed during mould matched moulds What system was to determine, angle is ensured by mould.Bending between a-quadrant and B area carries out the shaping at other positions again after terminating, Finally remove stopper protrusion 50 and obtain shaped article 1.

Stopper protrusion 50 can also be substituted by the scheme of the forms such as the breach of hole or edge, and perforate should in certain plate face Premised on the basic function for not influenceing product, the positioning units for providing corresponding construction in addition are adapted to it.
