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 wood artificial board production technology, particularly the production method of the curling accumulation wood-based plate of a kind of two-way mold pressing.
background technology:
Wood artificial board divides several, and a kind of is glued board, first round log is peeled into after veneer, and drying, gluing, by hot-forming after the crisscross stacked laying of wood grain, be longitudinally full wafer plate conventionally, is laterally some small pieces plate splicings.The second is LVL plate (laminated veneer lumber laminated wood), is that by wood grain, full wafer plate is superimposed rear hot-forming in the same way by the veneer after rotary-cut.The third is PSL plate (parallel strand laminated wood), is first the full wafer veneer after rotary-cut to be longitudinally cut into the rectangular arrow gauge of the about 20mm of width, then stacked be hot pressed into sheet material parallel with slash grain.The 4th kind is that LSL plate (laminated strand lumber) is to use special production technology by log cut growth batten, after drying, applying glue, batten is stacked together by parallel texture, is finally pressed into stock board.The 5th kind is wood reconstituted material plate, be small-bore timber through rolling or beating into after fibre bundle strip, then splice in the same way laminating hot pressing and become sheet material.
Hot press has side direction hot press and hot press vertically.The side pressure mould that side direction hot press uses is opening " door " word shape towards avris, and material spreads in mould, and hydraulic cylinder drives moulded board from right-to-left press-in die." door " word shape that the end compression mould that hot press uses is vertically opening upwards, material spreads in mould, and hydraulic cylinder drives upper molded plate press-in die from top to bottom.Above-mentioned five kinds of plates are generally only used hot press compacting vertically.
Glued board, LVL plate upper and lower surface are full natural wood veins, and lines is attractive in appearance.Glued board transverse strength is greater than LVL plate, longitudinal strength is weaker than LVL plate respectively pluses and minuses, and these two kinds of plates all require large round log rotary-cut could meet longitudinal plate and want complete sheet plate, and material cost is high.Meanwhile, there is obvious layer structure the side of glued board, there is no the natural lines of original wood plank.PSL plate does not require complete slice plate, and cost is low but intensity is not so good as first two plate, and simultaneously owing to large veneer need to being cut into fillet, production technology is comparatively complicated, and plate face wood grain is mixed and disorderly.LSL can realize mechanization serialization and produce, but the superficial makings of sheet material is mixed and disorderly, has the vestige of obvious small strip splicing.Wood reconstituted material plate can make full use of rod and roll slivering bundle, but consumption glue amount is large, and complex manufacturing, does not still have Industry Promotion at present.
summary of the invention:
The object of the invention is to overcome above-mentioned defect, comprehensive five kinds of plate advantages, provide the production method of the curling accumulation wood-based plate of a kind of two-way mold pressing.
The solution of the present invention is: comprise in round log rotary-cut, dry, impregnation, mould lay, hot pressing, it is characterized in that: mould is divided into side pressure mould, suppresses end compression mould vertically, and side pressure mould is assembling die, lower L shaped plate, upper cover plate, consists of; In mould, be laid in the lower L shaped plate of side pressure mould stacked rotary cut venner or the curling rear horizontal next-door neighbour of veneer is arranged to laying, rotary cut venner is laid rear upper cover plate and is driven and overlayed the rotary cut venner upper surface after laying by the cylinder on hot press, upper cover plate and lower L shaped plate are combined into opening to " door " glyph group mould of avris, then side direction hot press hydraulic cylinder drives side form pressing plate side direction to be pressed in assembling die outward by assembling die avris opening, makes the intermediate products of the veneer compacting formation square shape after laying; After assembling die separately being resetted after the intermediate products moulding of square shape, take out square shape intermediate products, again by several square shape intermediate products laterally and drain in the end compression mould of hot press vertically, and make the two side of several square shape intermediate products two side-flank surfaces next-door neighbour end compression moulds side by side, then hot press hydraulic cylinder drives upper molded plate to be pressed into end compression mould from top to bottom vertically, takes out product after hot briquetting.
The invention has the advantages that: first side pressure makes rotary cut venner be irregular curling shape, intermediate products are hot pressed into plate side by side more vertically, with regard to veneer, the involute song of sheet material unit is larger than single sheet mechanics section modulus, and after combination, same compound section modulus is large, thereby mechanical strength improves.After hot pressing, the surface of sheet material and cross section, due to curling shape unit parallel longitudinal cupping transverse curl, show annual ring texture after compacting, convergence natural timber, and aesthetics is good.
