Abstract
The invention provides a production method for curly stacking artificial boards in a bidirectional die-pressing manner, relating to the production technology of the artificial boards. The production method comprises the following steps of rotatably cutting a log, drying, gumming, laying in a die, and hot-pressing. The production method is characterized in that: a die is divided into a lateral pressing die and a vertical pressing die for vertically pressing up and down; the lateral pressing die is a combined die and consists of a lower L-shaped board and an upper cover board; rotary cutting single boards are laminated in the lateral pressing die, or the single boards are transversely and adjacently arranged and paved after being curled, and then an air cylinder drives an upper pressing plate to press and adhere on the upper surfaces of the paved rotary cutting single boards; a back side drives a side die pressing board towards a hydraulic cylinder of a hot-pressing machine to laterally press, so as to form a plurality of intermediate products in the combined die; the intermediate products are transversely arranged in the vertical pressing die side by side; a hydraulic cylinder of a vertical hot-pressing machine drives an upper die pressing board to press into the vertical pressing die; and a product formed by heating is taken out. The production method has the advantages in that: the board is formed by laterally pressing and then vertically pressing up and down; a curling sub unit in a sheet material has a larger module when being compared with the single-sheet-shaped mechanical section, and the section module of the same combined manner after the combination is large, so that the mechanical strength is improved.
Description
Technical field:
The present invention relates to the wood artificial board production technology, particularly a kind of two-way mold pressing is curled and is piled up the production method of wood-based plate.
Background technology:
Wood artificial board divides several kinds, and a kind of is glued board, and after elder generation was peeled into veneer with round log, through dry, gluing, hot-forming by the crisscross range upon range of laying of wood grain back, common was the full wafer plate vertically, laterally is some small pieces plates splicings.Second kind is LVL plate (laminated veneer lumber laminated wood), is that the superimposed back of full wafer plate is hot-forming in the same way by wood grain with the veneer after the rotary-cut.The third is PSL plate (a parallel strand laminated wood), is the rectangular arrow gauge that earlier the full wafer veneer after the rotary-cut longitudinally is cut into the about 20mm of width, parallel with the slash grain then range upon range of sheet material that is hot pressed into.The 4th kind is that PSL plate (laminated strand lumber) is to use special production technology with log cut growth batten, after oven dry, applying glue, batten is stacked together by parallel texture, finally is pressed into stock board.The 5th kind is the wood reconstituted material plate, is small-bore timber after rolling or beating into the fibre bundle strip, splices laminating hot pressing more in the same way and becomes sheet material.
Hot press have the side direction hot press and vertically hot press.The employed side pressure mould of side direction hot press is opening " door " word shape towards avris, and material is spread in the mould, and hydraulic cylinder drives moulded board and is pressed into mould from right to a left side.The employed end compression mould of hot press is " door " word shape that opening makes progress vertically, and material is spread in the mould, and hydraulic cylinder drives upper molded plate and is pressed into mould from top to bottom.Above-mentioned five kinds of plates generally only use hot press compacting vertically.
Glued board, LVL plate upper and lower surfaces are full natural wood veins, and lines is attractive in appearance.The glued board transverse strength is weaker than the LVL plate greater than LVL plate, longitudinal strength respectively has pluses and minuses, and these two kinds of plates all require big round log rotary-cut could satisfy vertical plate and want complete sheet plate, and material cost is high.Simultaneously, there is tangible layer structure the side of glued board, does not have the natural lines of original wood plank.The PSL plate does not require the complete slice plate, and cost is low but intensity is not so good as preceding two kinds of plates, owing to need big veneer is cut into fillet, production technology is comparatively complicated simultaneously, and plate face wood grain is mixed and disorderly.LSL can realize mechanization serialization production, but the superficial makings of sheet material is mixed and disorderly, and the vestige of obvious small strip splicing is arranged.The wood reconstituted material plate can make full use of rod and roll the slivering bundle, but consumption glue amount is big, and complex manufacturing does not still have Industry Promotion at present.，
Summary of the invention:
The objective of the invention is to overcome above-mentioned defective, comprehensive five kinds of plate advantages provide a kind of two-way mold pressing to curl and pile up the production method of wood-based plate.
Scheme of the present invention is: comprise laying, hot pressing in round log rotary-cut, drying, impregnation, the mould, it is characterized in that: mould is divided into the side pressure mould, suppresses the end compression mould vertically, and the side pressure mould is an assembling die, by L shaped plate, upper cover plate are formed down; The mould middle berth is made as at the following L shaped plate laminated rotary cut venner of side pressure mould or with the laterally next-door neighbour's arrangement laying of the curling back of veneer; Rotary cut venner is laid the back upper cover plate and is overlayed the rotary cut venner upper surface after laying by the drive of the cylinder on hot press upper cover plate; Upper cover plate is combined into " door " glyph group mould of opening to avris with following L shaped plate; Then side direction hot press hydraulic cylinder drives side form pressing plate side direction outward by assembling die avris opening and is pressed in the assembling die, makes veneer compacting after the laying form the intermediate products of square shape; After the intermediate products moulding of square shape square shape intermediate products are taken out in the assembling die back that separately resets; Again laterally and drain in the end compression mould of hot press vertically with several square shape intermediate products; And make the two side of several square shape intermediate products two side-flank surfaces next-door neighbour end compression mould side by side; Then the hot press hydraulic cylinder drives upper molded plate and is pressed into the end compression mould from top to bottom vertically, takes out product after the hot briquetting.
The invention has the advantages that: first side pressure makes rotary cut venner be the curling shape of non-rule; Intermediate products are hot pressed into plate side by side more vertically; Sheet material crimped subelement is bigger than single sheet mechanics section modulus with regard to veneer, and same compound section, combination back modulus is big, thereby mechanical strength improves.The surface of sheet material and cross section are owing to the shape unit parallel longitudinal cupping transverse curl that curls after the hot pressing, and the compacting back shows the annual ring texture, the convergence natural timber, and aesthetics is good.
