Description
Technical field
The present invention relates to metallic plate punching field shaping technique, more particularly to a kind of processing of the part with bending side
Method.
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 figure 4, 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 arrangement, B by boundary of ab boundary lines on face
There is the relation being similar between A and B between C, C and D.The plate face in two regions is merely pressed into specific angle simultaneously
It 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 the position of boundary line
And it is fixed.
The content of the invention
It is an object of the invention to provide a kind of processing method of the part with bending side, is easy to processing plate material parts to have
There is angle requirement between irregular peripheral profile and each region portion of part.
A kind of processing method of the part with bending side, comprises the following steps：
Material plate is provided A,；
B, plane setting-out blanket is prepared, the leftover pieces beyond the shaped article profile on material plate is cut off and obtains plane and put
Sample blanks plate；
C, limiting section is set on the boundary line of the kink of adjacent area A, B on plane setting-out blanket；
D, plane setting-out blanket is positioned on lower mould；
E, move down mould and implement mould assembling action；
F, mould is separated, stamping parts is removed and had both obtained required workpiece.
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.
Brief description of the drawings
Fig. 1 is the schematic diagram that material plate is provided in the present invention, and edge profile is designed on raw material plate；
Fig. 2 is the plane full-size drawing of product to be formed；
Fig. 3 is the punching course dimensional structure diagram of the present invention；
Fig. 4 is the dimensional structure diagram of product to be formed；
Fig. 5 is the partial enlarged drawing in Fig. 2.
Embodiment
With reference to Fig. 1,2, there is the processing method of the part of bending side, comprise the following steps：
Material plate is provided A,；
B, plane setting-out blanket 1 is prepared, the leftover pieces 2 beyond the shaped article profile on material plate is cut off and obtains plane
Setting-out blanket 1；
As shown in figure 1, the contour line of product is set out in plate face, can be in electricity if Product Precision and quality requirement are high
The generation of processing pattern is completed in brain, is completed by numerical control machining center, as specific cutting is completed in wire cutting or laser cutting machine
Task.
Limiting section 10 is set on the boundary line of the kink of adjacent area A, B on plane setting-out blanket 1 C,；Limiting section
Premised on 10 Scheme Choice foundation conveniently positions and do not interfere with the quality of product, subsequent content is described in detail to this.
D, plane setting-out blanket 1 is positioned on lower mould 20, limiting section 10 coordinates spacing with the position-limiting unit on lower mould 20；
E, move down mould and implement mould assembling action；
F, mould is separated, stamping parts is removed and had both obtained required workpiece.
In such scheme, basic technical thought is exactly to be determined the geometric center for treating bending part, in fact right
Sheet material is implemented during Bending Processing two faces can not possibly be allowed to form an intersecting solid line, and in fact the intersection in two faces is with arc
The form transition of shape face, so the boundary line of foregoing adjacent area A, B kink is friendship herein for convenience of explanation
Boundary line refers to the region of arc transiting surface.When being related to the statement below, understood with this implication.
The boundary line end edge of the kink of adjacent area A, B on plane setting-out blanket 1 is pre- along shape is extended laterally
Stay or add limiting section 10.Limiting section 10 can be reserved in the lump when processing edge profile by laser or wire cutting machine.
Preferably, described limiting section 10 stays in advance while leftover pieces 2 are cut off, limiting section 10
Contour shape is convex, and one end part and the setting-out blanket 1 of the web 11 of limiting section 10 keep former integrative-structure, and wing plate 12 is located at
The other end of web 11, as shown in Figure 5.
Position-limiting unit on described lower mould 2 is guide channel 21, and two end edges 121 of the wing plate 12 on limiting section 10 are with leading
Limitation limiting section 10 is coordinated to be moved along mould matched moulds direction to passage 21 is spacing.
Preferably, described lower mould 20 is the cavity plate that forming surface is V-arrangement, and the constraint of guide channel 21 guides limiting section
10 push setting-out blanket 1 with upper mould together moves down.
After treating bending part whole completion of processing, limiting section 10 and deburring processing are removed.
, can if the boundary line position of adjacent area A, B kink does not specially require in such scheme
Breach is opened up to implement opening or the both ends of boundary line, it is so corresponding to be correspondingly arranged locating dowel in lower mould 20 and equally realize
Spacing movement in the positioning of bending part and punching course.
