Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Real-wood integrated material is colded pressing the process of brake forming, and concrete steps comprise:
1, select the thickness of veneer according to the flexibility of wooden piece, then aberration is selected in classification, determines dash board or central layer, ensures dash board and the precision of central layer on thickness, and ensures roughness and the cleannes of dash board and core plate surface, be conducive to the infiltration of glue; Carry out matching board according to different products, the reconstituted veneer be made into utilizes homemade bender of colding pressing to carry out pressing and forming, utilizes the bending veneer thickness of the method to reach 8 ~ 10mm.
2, dash board and central layer table are coated with woodenware glue, and together, bonding time controling is in 10 minutes in split; Wherein, the woodenware glue used in step 2 is esterification starch and chloroprene rubber breast mixture, and mixed proportion is 6: 4, and this woodenware glue does not contain poisonous volatile substance, health environment-friendly
Through long-time checking, use that the woodenware glue bond intensity of this proportions is large, precompressed is good, resistance to ag(e)ing, resistance to water and Good Heat-resistance.Through and during the long-time bending conservation degree that scribbles isocyanate based adhesive test, the twisted plate scribbling esterification starch and the newborn mixture of chloroprene rubber has the maintenance flexibility of 95%, and to scribble isocyanate based adhesive twisted plate be 87% maintenance flexibility.
3, pressing mold is placed in for shaping surface, in dash board surface cushion, iron plate is as backboard, by colding pressing, iron plate, dash board and central layer are pressed in the forming surface of pressing mold by bender, with fixture, backboard, dash board and central layer are fixed in the forming surface of pressing mold, shape 30 ~ 45 minutes, temperature is 35 ~ 50 DEG C; Wherein Mold Making is particularly important, is namely divided into a pressing mold and multiple fixture.Pressing mold is formed by the wooden model system of turning over, and utilizes product pattern milling wooden model.25% of market die manufacturing cost.
4, taken off from the demoulding pressing mold by product, upper puller, control bending time 24 hours, 72 hours placed by thermostatic chamber, and thermostatic chamber temperature is 25 ~ 45 DEG C, shaping.
The angle of bend of bending part determines the thickness of veneer, and namely angle of bend is larger, and veneer needs thinner, thicker on the contrary, and demoulding standing time is that the angle large time is few, and angle is long for little standing time, is generally 72 hours draw and fixes time.
Cold pressing bender by multiple fixture and pressing mold is supporting completes making, and come by multiple backboard and multiple fixture, recycle, Productive statistics is little, and output is higher than several times of routine.
As shown in Figure 1, it comprises workbench 1, described workbench 1 two ends are longitudinally provided with a hydraulic cylinder 2 respectively, two hydraulic cylinders 2 are oppositely arranged, one of them hydraulic cylinder 2 is connected with a pressing mold 3, another hydraulic cylinder 2 is connected with a push pedal 4, pressing mold 3 is provided with arc-shaped notch 5 on the end face that it is relative with push pedal 4, pressing mold 3 and push pedal 4 are all provided with longitudinal slideway 6 on workbench 1, and can only move along respective slideway 6, workbench 1 is provided with support 7, and support 7 is provided with longitudinal crane runway 8, and crane runway 8 is provided with electric crane 9.
The position of side between pressing mold 3 and push pedal 4 of described workbench 1 is provided with horizontal hydraulic cylinder 2, and this hydraulic cylinder 2 end is connected with push pedal 4.
Described pressing mold 3 is frame structure, and its surface needs to have various fabrication hole according to technique, so that assembling jig and meet various processing technology demand.
Wherein, the shape that press mold can bend as required is changed.The extexine that pressing mold contacts with timber adopts the thick v-cr-mo alloy steel of 5mm to make, Chromium in Alloy steel content 18%, molybdenum content 2%, content of vanadium 4%.V-cr-mo alloy steel has high-wearing feature, high compressive strength have good dimensional accuracy.
During production, adopt wooden model shaping, one end of wooden model and arc-shaped notch 5 shape of pressing mold 3 adapt.During production, wooden model is put well between pressing mold 3 and push pedal 4, the multilayer wood chip and iron plate stacking that brush glue are put into arc-shaped notch 5 place of pressing mold 3 and are against on wooden model, wood chip and iron plate together extrude by the equipment that starts, wood chip and iron plate are expressed in the forming surface of wooden model, with special fixture, the wood chip after distortion is shaped together with iron plate in the forming surface of wooden model again, whole wooden model is taken off enter subsequent processing afterwards.Because the weight of wooden model own is comparatively large, electric crane 9 and horizontal hydraulic cylinder 2 operate in order to indirect labor.
