Embodiment 1

[0047] Example 1: Taking Fraxinus mandshurica as an example, the bent and deformed foot of a chair was made, and the manufacturing method was as follows:

[0048] Such as figure 1 , figure 2 As shown, the size of the ash square timber is 950mm×47mm×32mm through the material production. Take the above-mentioned square material into a cooking tank, steam it with 100℃ steam for 140min, and set the pressure to 0.4Mpa; After softening the ash square material wool, immediately pressurize the ash with mold, steel belt, stopper, etc. Bend and deform as attached image 3 The curve shape shown; put the bent and deformed manchurian ash wool together with molds, steel strips, etc. into the integrated drying and ultra-high temperature heat treatment kiln for drying and ultra-high temperature heat treatment. The drying stage is when the dry bulb temperature is about 55 Begin at ℃, and then gradually increase the temperature to about 125℃. The temperature difference between the dry and wet bul...

Embodiment 2

[0052] Example 2: Taking Chinese fir as an example, the bent and deformed back foot of a chair is made, and the manufacturing method is as follows:

[0053] Through timber making, the size of Chinese fir square timber is 950mm×47mm×32mm. Take the above-mentioned square material into a cooking pot and boil it in hot water at 80°C for 130 minutes; after the fir wool is softened, immediately use a mold, steel belt, stopper, etc. to press and bend the ash to form a curved shape; The bent and deformed fir wool, together with molds, steel strips, etc., are put into the integrated drying and ultra-high temperature heat treatment kiln for drying and ultra-high temperature heat treatment. The drying stage is that the dry bulb temperature starts from about 45°C, and then the temperature is raised to about 115℃, the temperature difference between the dry and wet bulbs gradually expanded to 25℃, reducing the moisture content of the wood to 4%~5%, and then the dry bulb was quickly heated to 1...

Embodiment 3

[0055] Example 3: Taking yellow rattan as an example, the bent and deformed back foot of a chair is made, and the manufacturing method is as follows:

[0056] Through lumber making, the specifications of yellow rattan square lumber are 8000mm long and 70mm in diameter. Take the above round wood into a cooking tank, steam it with 100℃ steam for 20 minutes, and set the pressure to 0.5Mpa; After the yellow vine round wood wool is softened, immediately press the yellow vine with mold, steel belt, stopper, etc. Bending and deforming into a curved shape; Put the bent and deformed yellow rattan wool together with molds, steel strips, etc. into the integrated drying and ultra-high temperature heat treatment kiln for drying and ultra-high temperature heat treatment. The drying stage is when the dry bulb temperature is about 55°C At the beginning, the temperature was raised to about 125°C in stages, and the temperature difference between the dry and wet bulbs was gradually expanded to 25°C...

Abstract

The invention relates to the technique field of wood processing treatment, in particular to a method for blending and setting wood. The method for blending and setting wood comprises steps of sorting treatment, softening process, blending and deforming, setting, temperature reduction and humidifying, and cooling and health preserving. The method solves the problems existing in the existing traditional wood blending and distortion technique that wood utilization ratio is low, obtained products have poor size stability and high recovery rate of radius of curvature and is easy to crack, deform, decay and go moldy, etc.

Description

Technical field [0001] The invention relates to the technical field of wood processing and treatment, in particular to a method for bending and shaping wood. Background technique [0002] Bending and deformed wooden products are loved by people for their elegant and concise styles, graceful curves, fine manufacturing techniques, and better mechanical properties. However, traditionally used to make bending deformation wood products, one is the use of sawing method, this method because after the wood is sawed, a large number of fibers will be cut, so that its strength is reduced, especially in the production of large bending angles The strength of the product is particularly reduced, and the yield is low, the wood waste is serious, and the types of wood resources that can be processed and utilized are few. The other is to use the dry setting method. Although this method can save a lot of wood, the resulting wood products have poor dimensional stability, high curvature radius recov...
