Embodiment Construction

[0034] Inner model of the present invention such as figure 1 Shown: 1 is a U-shaped mold with a 4 mm fillet R at the bottom of the mold, 2 is a pin for clamping the mold, 3 is a steel pressure plate, A layer is a carbonized layer, B layer is a natural color veneer layer, and C layer In order to strengthen the balance layer horizontally, the combination of A, B, C and R rounded corners can achieve better anti-deformation ability, and can form a natural and rich cross-section texture to meet people's visual needs.

[0035] Manufacturing method of the present invention, comprises the steps:

[0036] (1) Material selection, rotary cut eucalyptus and cut it into a veneer with a longitudinal length of 1270 mm, a transverse width of 135 mm, and a thickness of 1.7 mm, and cut the veneer small or residual material into a length of 120 mm along the grain Short strips, dry the veneer strips to a moisture content of 12%;

[0037] (2) Vacuum impregnation method is used to impregnate the ...

Abstract

The invention discloses a method for manufacturing laminated veneer lumber by using wood to solve the problem that the laminated veneer lumber with high strength and simulated rich textures cannot be produced in the conventional methods. The method comprises the following steps of: (1) manufacturing the wood into veneers with the thickness of 0.3-5mm, and performing gum dipping and drying on the veneers, wherein the length and width dimensions of the veneers are the same as those of an internal mold of a mold, or the width dimension of the veneers is consistent with that of the internal mold and the length dimension of the veneers is a fraction of that of the internal mold; (2) superposing the veneers to obtain a blank, putting the blank into the internal mold of the mold, and ensuring that an included angle between a groove bottom and a groove wall is a fillet with the radius of R, wherein the R is more than or equal to 3mm and less than or equal to 20mm, the groove wall is provided with corresponding holes on the same horizontal plane, and the corresponding holes are matched with a pin; (3) pressing the blank in the internal mold of a movable mold of a press, making a pressing plate positioned below the corresponding holes, locking the internal mold by using the pin to penetrate the corresponding holes, and heating and curing the locked internal mold and the blank; and (4) cooling, detaching the pin, demolding the blank, ensuring that the exposed surface of the blank is provided with simulated annual rings, putting the blank in a natural environment, sheeting according to the annual rings of the blank, and ensuring that sheets have the simulated annul rings.

Description

Technical field: [0001] The present invention relates to a method of manufacturing laminated lumber from wood. Background technique: [0002] The existing manufacturing method of wood phenolic resin laminated material is such as the technical scheme disclosed in Chinese patent ZL93105062.6. material. The textures of laminated lumber and its sliced ​​sheets are horizontal parallel textures or laminated textures produced by monotonous laminations. Since the laminates are made of wood rotary cutting or planing, the thickness is 0.5-2.5mm. The veneer itself can hardly see the natural texture of the wood. After the lamination is hot-pressed into laminated lumber, most of them only have the horizontal parallel texture produced by the lamination. Changes, without the rich texture of natural wood grain, and the appearance of texture is not clear. Production costs are high. Invention content: [0003] The purpose of the present invention is to provide a method for manufacturing...
