Further, above-mentioned modified epoxy is nitrile rubber or polyacrylate.

Further, above-mentioned transparent epoxy resin is polyester resin.

Further, when above-mentioned punch forming is plane curved surface, slot segmentation is along perpendicular to arcwall face on stone material surface layer Continuously cut parallel groove in the direction of expansion.

Further, when above-mentioned punch forming is abnormal curved surface, slot segmentation is the grid groove on stone material surface layer.

Further, above-mentioned plastic material basic unit is aluminium sheet, copper coin or acrylic board.

It is specifically described below in conjunction with the accompanying drawings, the invention reside in using lithotome flat board as surface layer, to have malleable change Property epoxy resin is tack coat, with mechanical plastic material(Such as iron, copper, aluminium or other alloy materials), or thermoplasticity material Material(Such as acrylic, TPV, PE)Flat board is basic unit.It is bonded the plane composite material of three-decker.And in this composite Stone material surface layer cutting certain depth groove, make stone material surface layer keep pattern unity and coherence in writing it is continuous, but stress segmentation flat board.Make modeling Property is processed into possibility.Three steps of preparation process point:

The first step, the preparation of composite:

As shown in Figure 1:It is prepared by the bonding of the plane composite material of three-decker:This modified epoxy is different from current market Brittle epoxy resin after the upper solidification for bonding stone material, but it is flexible and drawability, such as nitrile rubber or polypropylene Acid esters etc., making composite, the resin for playing adhesive effect is drawn with basic unit phase-contact surface with the plastic deformation of basic unit in deformation Stretch, compress, but remain in that with stone material contact surface indeformable.And after the compression of ordinary epoxy resin Tensile, it is broken such as stone material Split so that stone material layer and base material depart from.

Second step:Composite pre-processes:

In the stone material surface layer of the synthetic material prepared, certain thickness internal cutting slot segmentation, surface layer is set to form overall texture continuity, But the entirety that stress is locally isolated.Product according to final molding is that plane curved surface or abnormal curved surface are divided into two kinds of cutting sides Formula:If plane curved surface, then a parallel, fixed width is continuously cut along perpendicular to the direction of arcwall face expansion on stone material surface layer The groove of degree;If abnormal curved surface, then the grid groove of one fixed width is cut on stone material surface layer, and mesh segmentation groove can be any Pattern, however it is not limited to co-ordination.Make composite plate in punching course, and the stress after shaping is for caused by local stone material surface layer Tensile strength and bending strength are less than the yield limit of stone material, so as to embrittlement or crushing during avoiding.And make in corresponding area The peel strength of stone material-resin is less than its bonding force, avoids stone material and basic unit from departing from.

The spacing of slot segmentation and the Computing Principle of width:To make the texture globality of the stone material surface layer after punching press reach most It is good, the width of slot segmentation should be reduced as far as possible in the case where meeting above-mentioned stress condition, and increase the spacing of slot segmentation.

1st, the minimum widith of slot segmentation calculates:While slot segmentation in separating large region is small area region stress, The surface area of seam also acts as the effect for allowing redundancy to deform, and as shown in Figure 2, i.e., in stretching, the surface area of composite increases Add(Such as extrados);During compression, surface area reduces(Such as intrados).Although the modified epoxy as adhesive is with basic unit The stretchable compression of plastic material changes area, but the stone material on top layer does not have plastoelastic feature, and surface area is immutable.By The difference of product-forming, the design of the stretching die influence different with Sheet Metal Forming Technology, and each position on continuous curve surface, on direction Radius of curvature change, surface area stretching/compressing is than different.Enough slot segmentations are reserved in corresponding site according to process characteristic Width, resin in the position groove is set to extend(Compression)Total surface area afterwards is equal to Pressing Deformation plus stone material total surface area sum The total surface area of basic unit afterwards.

2nd, the maximum distance computation of slot segmentation(The density of slot segmentation in designated area):For any selected stone material surface Raw material used by layer, the yield limit value of its bending strength and tensile strength is understood through actual sample test.To one into The complete continuous curve surface of type does region segmentation according to local radius of curvature, and stretching suffered by the stone material surface layer in region is made by calculating Intensity and bending strength are less than its yield limit.And the density for reducing slot segmentation as far as possible is imitated with obtaining optimal texture continuity Fruit.

To use diel BxD rectangular regions to be made outer spherical cambered surface of the radius of curvature as R(Abnormal curved surface) Exemplified by(Accompanying drawing 5):When composite plate does Pressing Deformation, mould outer layer(Cavity plate 5)Pressed F for stone material surface layer, so as to On the point of mould and face layer contacts, the power F1 for being tangential to spherical radius R is produced by frictional force, this contact point is rectangular in BxD Four angle point JKLM in shape region(J, M in profile).And mould internal layer(Punch-pin 6)For basic unit the strong point in BxD regions Central point C(Point of contact of the basic unit with mould internal layer-radius for r sphere).This power F1 is through resolution of vectors, equivalent to stone material surface Layer generates horizontal direction pulling force;Vertically to generation pressure, And an equivalence is produced in F reverse stripping pulling force F ' to resin and stone material binding site.When this pulling forceJ-M is acted on to cut Face exceedes the ultimate tensile strength of stone material(Generally 15Mpa), stone material is pulled off;OrPressure exceedes stone for C points torque The bend yield strength noted of material(According to U.S.'s ASTM-C880 standards, 400-1600psi, i.e. 2.8-10.3Mpa are typically in the range of)When, Stone material surface layer can fracture in C points and produce comminuted damage;Or concentrate on the stripping pulling force F ' of C points, intensity be more than resin with The bonding force of stone material, then surface layer and basic unit are separated.

Above-mentioned solution method is that shown local bXd blockages are divided into stone material surface layer BxD regions.(This is vertical vertical Crosscutting secant simply to illustrate that embody a kind of scheme, in fact, slot segmentation can be arbitrary graphic pattern, however it is not limited to co-ordination.) Accompanying drawing 3,4.By such cutting, the contact point of cavity plate and surface layer is on the angle point of each bXd blockages, so that pressure F Uniformly it is distributed on the angle point of each bXd blockages, and punch-pin is equally taken a walk for the strong point of basic unit in each bXd The central point of blockage.When pressure F is constant, the stress of composite has obtained very because being dispensed on each blockage Big improvement.Force analysis is as shown in Figure 6:

In theory, in a given BxD region, b, d value are smaller, i.e. cutting groove density is bigger, and stress condition is better.But It is that density is bigger, the texture continuity destruction of lithotome is bigger.Meet that the stretching of stone material and bending are bent when b, d value calculate stress It when taking the limit, should maximize b, d value.

After the pretreatment of the composite of second step, this material is stamped/hot bending machine-shaping and obtain curved surface and stand The finished product of body.

3rd step:The repairing of finished product:

Using transparent(Conventionally used for repairing stone material hole, hole, split after the solidification of line etc. in brittle)Epoxy resin(It is referred to as in industry Polyester resin)Joint filling, cutting groove is filled and led up again concordant with stone material surface layer, and polish to form complete table through normal polishing program Face decorative layer.Because each fritter bxd regions keep constant in BxD relative position, the continuity of stone texture is able to Keep.Influenceed by eye-observation angle, the surface after filling and leading up is seemed still to be complete overall, and the aesthetic feeling of lithotome is kept It is constant.Certainly, in order to obtain special decorative effect, cutting groove can not do joint filling processing.What is obtained is exactly special post Shape arranges(Abnormal curved surface)It is or arranged in parallel(Plane curved surface)Both local, and continuous curved surface and texture.

The present invention is using modified epoxy bonding lithotome surface layer thin plate and plastic material basic unit, by pre-segmentation groove Working process, plane composite material plate is used stretching die stamping and plastic working, plane curved surface is realized with planar materials With the product of abnormal curved surface.Than two kinds of curved surface processing modes of aforementioned conventional, the use of material is saved, reduces material cost, It is particularly evident in the luxurious level stone material of high value;The pollution in material loss and process is also reduced, and makes product can be with Large-scale batch production, greatly improve labor productivity.And because lightweight manufactures, improve the applicable model of product Enclose, and greatly reduce logistics cost and product breakage rate.

The foregoing is only presently preferred embodiments of the present invention, all equivalent changes done according to scope of the present invention patent with Modification, it should all belong to the covering scope of the present invention.
