Description
Technical field
The utility model relates to woodwork plate field, is specifically related to a kind of rotary-cut board core material woodwork plate of internal stress free.
Background technology
Core-board is commonly called as lumber core, is to be formed by glue laminated Wood block floor in the middle of two panels veneer.Middle plank be by the natural plank side of high-quality after heat treatment (i.e. drying chamber oven dry), be processed into the batten of certain specification, be spliced by plate joggling apparatus.Spliced plank two sides respectively covers two-layer high-quality veneer, then makes after hot and cold press glue laminated.Central layer due to woodwork plate is that many battens are spliced, and in order to make, woodwork plate integral surface is smooth, even density, thus to the machining accuracy of each batten and processing request relatively high, otherwise the plate face of woodwork plate there will be the defects such as depression or bulge; In addition by wood sawing Cheng Duogen batten, its timber loss is relatively large.In order to overcome above-mentioned defect, occur that the similar patent No. is: the woodwork plate structure of 01133469.X on the market, splicing batten has been replaced with the rotary-cut plate after processing, because rotary-cut plate is an entire plate, so the smooth problem of the space of a whole page overcoming woodwork plate; In addition with the rotary-cut plate of timber rotary-cut as central layer and splice plate bar as compared with central layer, cutting times is few, and wood losses is few, has saved timber.
But the woodwork plate of this structure, because rotary-cut plate is as plate core, and rotary-cut plate is in the process of rotary-cut, because the diameter of its both sides end face is not identical, so the rotary-cut plate after rotary-cut is curved slab, although rotary-cut plate can be made to become dull and stereotyped by technological means, but its inside then can produce internal stress, make its both sides end face form tight face and loose side, and the thickness of rotary-cut plate is thicker, its internal stress be processed into after flat board is larger.The number of plies of above-mentioned its rotary-cut plate of rotary-cut plate plate core is odd number, then its internal stress cannot be offset, and causes the woodwork plate produced to have bending hidden danger, reduces the qualification rate of product.
Summary of the invention
The purpose of this utility model is: overcome the deficiencies in the prior art, a kind of rotary-cut board core material woodwork plate of internal stress free is provided, the number of plies of rotary-cut plate is even number, and the tight face of rotary-cut plate and tight face are fixed, or loose side and the loose side of rotary-cut plate are fixed, the internal stress of rotary-cut plate is cancelled out each other, prevents woodwork plate from occurring buckling phenomenon, ensure the quality of woodwork plate; Vertical with the lines of rotary-cut plate B by rotary-cut plate A, the intensity of woodwork plate entirety can be improved, improve the serviceability of woodwork plate.
Technical solution adopted in the utility model is:
The rotary-cut board core material woodwork plate of internal stress free, comprise central layer and the panel of multilayer rotary-cut plate, described rotary-cut plate comprises rotary-cut plate A and rotary-cut plate B, described rotary-cut plate A is fixed between two pieces of rotary-cut plate B, the number of plies of rotary-cut plate A is even number, when fixing between adjacent rotary-cut plate, tight face and the tight face of rotary-cut plate are fixed, or the loose side of rotary-cut plate and loose side are fixed.
The further improvement project of the utility model is, the lines of described polylith rotary-cut plate A is identical, and the lines of rotary-cut plate B is vertical with the lines of rotary-cut plate A.
The utility model further improvement project is, described rotary-cut plate B fixes away from the end face of rotary-cut plate A side and panel, and described panel is rotary-cut skin or slicing skin.
The utility model further improvement project is, the thickness of described panel is more than 0.02 millimeter.
The utility model further improvement project is, described panel is provided with decorative layer away from the end face of rotary-cut plate A side, and described decorative layer is skin of paint or facing paper.
The utility model further improvement project is, the number of plies of described rotary-cut plate A is 2 layers or 4 layers.
The utility model further improvement project is, the thickness of described rotary-cut plate A is more than or equal to 4 millimeters.
The utility model further improvement project is, the thickness of described rotary-cut plate B is in the scope of 0.2 ~ 10 millimeter.
The utility model further improvement project is, the thickness of described woodwork plate is in the scope of 10 ~ 50 millimeters.
The beneficial effect of utility model is:
The first, the rotary-cut board core material woodwork plate of internal stress free of the present utility model, the number of plies of rotary-cut plate is even number, and the tight face of rotary-cut plate and tight face are fixed, or loose side and the loose side of rotary-cut plate are fixed, the internal stress of rotary-cut plate is cancelled out each other, prevent woodwork plate from occurring buckling phenomenon, ensure the quality of woodwork plate.
The second, the rotary-cut board core material woodwork plate of internal stress free of the present utility model, vertical with the lines of rotary-cut plate B by rotary-cut plate A, can improve the intensity of woodwork plate entirety, improve the serviceability of woodwork plate.
