Embodiment 1

[0046] Embodiment 1: Taking Mandshurica mandshurica as an example, the bent and deformed rear feet of a chair are made, and the manufacturing method is as follows:

[0047] Such as figure 1 , figure 2 As shown, through lumber making, the size of the mandshurica square material is 950mm×47mm×32mm. Take the above-mentioned square material into the cooking tank, steam it with steam at 100°C for 140min, and set the pressure to 0.4Mpa; after softening the square material of Fraxinus ash, immediately pressurize the ash with mold, steel belt, block, etc. bent and deformed as attached image 3 The curve shape shown; put the bent and deformed ash wool together with the mold and steel belt into the kiln for drying and ultra-high temperature heat treatment for drying and ultra-high temperature heat treatment. The drying stage is that the dry bulb temperature is from about 55 ℃, then increase the temperature to about 125 ℃ in stages, and gradually expand the temperature difference bet...

Embodiment 2

[0051] Embodiment 2: Take Chinese fir as an example to make the bent and deformed rear feet of a chair. The manufacturing method is as follows:

[0052] Through lumber making, the specifications of the Chinese fir square timber are 950mm×47mm×32mm. Take the above-mentioned square materials into the cooking pot and boil them with 80°C hot water for 130 minutes; after the fir wool is softened, immediately use molds, steel strips, stoppers, etc. to pressurize and bend the Mandshurica mandshurica into a curved shape; The bent and deformed Chinese fir wool, together with molds and steel strips, is placed in an integrated kiln for drying and ultra-high temperature heat treatment for drying and ultra-high temperature heat treatment for shaping. 115°C, the temperature difference between dry and wet bulbs is gradually expanded to 25°C, so that the moisture content of the wood is reduced to 4% to 5%, and then the dry bulb is rapidly heated to 180°C at 10°C / 0.5h, and kept for 2h for sett...

Embodiment 3

[0054] Embodiment 3: Taking Huangteng as an example, make the bent and deformed rear feet of a chair. The manufacturing method is as follows:

[0055] Through lumber making, the specifications of the obtained yellow rattan square timber are 8000mm in length and 70mm in diameter. Take the above-mentioned round material into the cooking tank, steam it with steam at 100°C for 20 minutes, and set the pressure to 0.5Mpa; after the softening treatment of the yellow rattan round material, immediately use the mold, steel belt, stopper, etc. to pressurize the yellow rattan Bending and deforming into a curved shape; put the bent and deformed yellow rattan wool together with molds and steel strips into an integrated kiln for drying and ultra-high temperature heat treatment for drying, ultra-high temperature heat treatment and finalizing treatment. In the drying stage, the dry bulb temperature is about 55°C At the beginning, then the temperature is raised to about 125°C in stages, and the...

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, in particular to a method for bending and shaping wood. Background technique [0002] Bent and deformed wooden products are loved by people for their elegant and simple style, graceful curve shape, fine craftsmanship, and better mechanical properties. However, traditionally used to make curved and deformed wooden products, one is the sawing method. In this method, a large number of fibers will be cut off after the wood is sawed, which will reduce its strength, especially in the production of large bending angles. The strength of the finished product is significantly reduced, and the yield rate is low, the waste of wood is serious, and the types of wood resources that can be processed and utilized are few. The other is to adopt the dry setting method. Although this method can save wood in a large amount, the resulting wooden products have poor dimensional stability, high recovery rate of ...
