Description

The production method of ultrafine cabinetwork board

Technical field

The present invention relates to a kind of production method of core-board.

Background technology

The plate core of the solid wood core-board that China produces at present mostly adopts slab, short and small material to make raw material.The technological process of its production is such: with slab, short and small material sawing becomes certain thickness hair plates, after the drying, hair plates is dug into the specification material with thicknesser, then with the cross-section one-tenth of specification material plate different in size, again plate is longitudinally dissectd into the core bar that width does not wait, with glue Pork-pieces core bar is sticked into the plate core base of certain width at last, after applying glue, on the plate core, below each sticking one deck central layer of pressing, be pressed into the first base of core-board through hot press, use the sander sand milling two sides of base just again, again at the sticking pressure surface plate in the outside of central layer, backboard has just obtained the core-board finished product.With the core-board of this explained hereafter, owing to the short material of the cross-section one-tenth of long material the plate of bulk longitudinally will be dissectd into the core bar that width does not wait, thereby wastage of material is will big; Owing to the plate of bulk is cut into the stress that still can't eliminate behind the core bar on the core bar, (the core bar that obtains with the timber sawing of limit portion particularly, because the contract with dry rate difference on its two sides, stress is bigger), thereby the core-board of making is yielding, end product quality is poor, can only be used for doing common buildings with material or exterior decoration material.We know that the core bar width of plate core material is very big to the quality influence of core-board, and core bar width is big more, and the plate face that the easy more stress that causes himself causes curls.The core bar width of plate core is more little, and the quality of core-board is just good more, and for this reason, national Specification: the core bar width of core-board does not allow 2.5 times greater than its thickness.But, obtain the more little core bar of width, plate will be by repeatedly sawing more, and the waste of raw material is also just big more, and production cost of products is also just high more.In fact, the width of the core bar of the core-board of present most manufacturer production all surpass the regulation of national standard, and its stress can't be eliminated also.Even produce the core bar according to national Specification, because the stress of core bar is not eliminated as yet, thickness owing to the central layer that sticks on plate core outside is too thin again, general 1.5-2 millimeter only, the thickness of panel, backboard that sticks on central layer outside is also extremely thin, have only the 0.2-0.3 millimeter, the tension force of central layer and panel and backboard can't be resisted the caused distortion of stress of core bar at all.Therefore, the surface flatness of core-board of making the plate core of wide core bar is relatively poor, and national standard allows the surperficial well-regulated ripple of core-board, and obviously, such core-board can't be used to make high-grade furniture.So people just with in fiberboard do bed material, on middle fiberboard face, stick wooden skin or glued board, make wood-based plate, make high-grade furniture with this wood-based plate.Though solved the problem of flatness like this, but but durability is undesirable: the time is long slightly, and fiberboard will absorb airborne moisture content, grows mould, greatly influence the quality of the furniture made from it, and the production cost of this fiber artificial board is also higher.

Summary of the invention

Task of the present invention is the shortcoming that will overcome in the existing core-board production method, provides a kind of available second growth wood, slab to produce to have core bar, the core bar of big width can not produce the production method of stress and Texturized ultrafine cabinetwork board.

The present invention finishes like this: with slab, short and small material sawing becomes the hair plates of desired thickness, after drying, with the plate of hair plates with thicknesser power blader established practice lattice thickness, plate is removed burr, cross-section two, the side's of formation plate, with square plate by roller press on square plate, vertically extrude along it below and have appropriate intervals, the impression that upper-lower position staggers mutually, with jigsaw machine and glue a piece is had again that the square plate of impression is bonding to become plate core base, again on plate core base, the sticking below central layer of pressing, promptly get the first base of core-board, all the other operations (these operations: on first base of producing again through common core-board, below with the sanding of coarse sand ray machine, again at the sticking pressure surface plate in the outside of first base, backboard, with fine sand ray machine sanding panel, on the backboard, below, it is panel, the outside of backboard, go to surpass the reservation part of core-board full-length and width again with straight flange saw and horizontal edge saw saw, use sand straight flange machine and sand horizontal edge machine sanding edges of boards again), just can obtain the ultrafine cabinetwork board finished product of accurate standard.

The degree of depth of impression can be according to the position of square plate and the stress decision of existence thereof, and in general, the degree of depth of impression can be the 1/3-2/3 of thickness of slab, is preferably 1/2 of thickness of slab.The section configuration of impression can be a rectangle, be right after the wedge shape of del below also can rectangle, it is even a crack that extrudes with blade thin, that have keen edge, preferably (this crack is the wedge shape that is right after del below the aforesaid rectangle, the special case when its transverse width is zero crack that extrudes when rolling across with circular saw bit thin, that have keen edge; Because the thin thickness of blade or circular saw bit, and timber has certain elasticity, and impression will become a crack by the wedge shape that certain width was arranged originally after blade or saw blade withdraw from).Because the impression of square plate above and below is the appropriate intervals that staggers mutually, even thereby the degree of depth of impression be 2/3 of thickness of slab, square plate can not disconnect from impression yet.

Because vertically extruding along it in the above and below of square plate, the present invention has the impression that appropriate intervals, upper-lower position stagger mutually, these impressions can eliminate the stress of square plate upper and lower faces, thereby can be out of shape by the side's of avoiding coiled sheet song, so just dimension saw need not be slit into narrow core bar, so square plate can directly be made the core bar and use.That is to say that square plate is exactly the bigger core bar of width.We can say that perhaps square plate is exactly a bigger core bar of a width that is pressed with many impressions, is not had the less core bar of cut many width to form by every impression separation.The waste of material that so just can avoid big plate sawing become narrow core bar and cause (comprising the waste that waste that saw kerf consumes and side shaping consume at least).Though ultrafine cabinetwork board of the present invention also is to make raw material with slab, short and small material, but the square plate made from this raw material, have impression (or being called wide central layer) can not be out of shape, need not be cut into narrow core bar, can keep its original and due maximum length and Breadth Maximum, thereby the joint of the plate core made from it is few, plate is big, the surface is flat, indeformable, the quality of the ultrafine cabinetwork board made from it will be better than the quality of existing core-board, thereby make it can be used as the sheet material of high gear furniture.Its production cost is low than existing core-board also, thereby can claim that such core-board is a ultrafine cabinetwork board.

The drawing explanation

Fig. 1 is the schematic diagram of ultrafine cabinetwork board of the present invention.Fig. 2 is the schematic diagram of compacting impression among the present invention.Fig. 3 is the longitudinal section schematic diagram that has the square plate of rectangle impression.Fig. 4 is the longitudinal section schematic diagram that has the square plate of wedge shape impression.

The specific embodiment

A collection of China fir slab and short and small material are sawn into thick 12.3 millimeters hair plates, after these hair plates dryings, become the specification material of 12.0 millimeters thick with the thicknesser power blader, the burr of all specification material are amputated formation side's plate, cross-section two obtains growing having and lacks, has the wide narrow square plate 1 that has.As shown in Figure 2, vertically extrude along it in the above and below of these side's plates 1 with roller press 2 and to have the impression 3 that staggers mutually in 12 millimeters intervals, 1 millimeter of width, 6 millimeters of the degree of depth, upper-lower position, form the square plate that has impression.

In general, the plate core thickness of the core-board of 16 millimeters thick is about 12 millimeters, according to national standard, the width of core bar should be not more than 2.5 times of thickness of slab, the width that is the core bar can be 40 millimeters, so, on wide 40 millimeters core bar, can extrude the impression of 12 millimeters of 3 wide 1 millimeter, dark 6 millimeters, space, and followingly can extrude 2 impressions.3 impressions and 2 following impressions above the core bar stagger 6 millimeters mutually, shown in Figure 3 come to this one wide 40 millimeters, be pressed with 3, the square plate (the core bar that promptly has impression) of following 2 rectangle impressions.The plate face of so wide square plate of 40 millimeters is broken down into four narrow core bars, and its central core connects together, like this, the stress of wide plate face just is divided into the stress of narrow core bar, and because the width after its decomposition is little, stress is also just much smaller, therefore, the stress that has the square plate of impression has just all been destroyed, just can not be Texturized.The situation of the square plate of other width by that analogy.Shown in Figure 4ly be one wide 62 millimeters and be pressed with 5, the square plate of following 4 wedge shape impressions.

Applying glue the square plate that is pressed with impression side by side, plate (selects the square plate of two about 2500 millimeters long to be placed on both sides, in the middle of short square plate is emitted on, adjacent two joint will stagger mutually, be discharged to till the required width) always, compress (also can be directly have on the hot press of side pressure compress) with the jigsaw machine, just obtain plate core base 4, its specification is 1240 millimeters * 2500 millimeters.On plate core base 4, be stained with central layer 5 below, be pressed into the first base of core-board through hot press, on first base, below with the sanding of coarse sand ray machine, again at the sticking pressure surface plate 6 in the outside of first base, backboard 7, just obtain the core-board semi-finished product, using fine sand ray machine sanding core-board surface of semi-finished again (is panel, on the backboard, below, panel just, the outside of backboard), go to surpass the reservation part of core-board full-length and width again with straight flange saw and horizontal edge saw saw, use sand straight flange machine and sand horizontal edge machine sanding edges of boards again, just can obtain the ultrafine cabinetwork board finished product (as shown in Figure 1) of 1220 millimeters * 2440 millimeters specifications of standard.
