Embodiment Construction

[0009] Taking the curved part of the dining chair as an example, first cut the appearance size of the plate into the part size. The size of the plate is 2cm in length, 0.2cm in width and 0.1cm in thickness compared with the reserved tolerance of the part size. Put the cut plate into the white steel Saturated steam is fed into the water tank for cooking, and the cooking time is related to the initial moisture content of the wood, the tree species and the thickness of the wood. Treat with saturated steam at 100°C for 15-40 minutes, add HB-60 softener (HB-60 softener can be purchased in professional stores) into the aqueous solution, the softener has a solid content of 60, a pH value of 4-5, and a diluted concentration of 5-8%; In order to prevent the blue staining of wood during cooking, 0.1% oxalic acid is also added to the aqueous solution to eliminate the blue staining. The softener can expand the volume of the lignin and cellulose non-crystalline regions of the wood, improve...

Abstract

The invention discloses an autoclaving rapid forming production method of a solid wood arc component. The method is characterized by comprising the following steps: cutting the external dimension of apanel into component dimension in a softening technology, ensuring that the reserved tolerance between the panel dimension and the component dimension is as follows: the length is 2cm, the width is 0.2cm, and the thickness is 0.1cm, putting the cut panel into a stainless steel water tank, leading saturated steam into the water tank to perform boiling, treating the panel for 15 to 40 minutes withthe saturated steam at 100 DEG C, adding an HB-60 softener into a water solution, and ensuring that the solid-containing content of the softener is 60, the PH value is 4 to 5, and the dilute concentration is 5 to 8 percent; adding 0.1 percent of oxalic acid into the water solution to prevent the phenomenon of wood blue stain during boiling. The method has the beneficial effects that the utilization rate of raw materials is high, compared with a sawing method, the utilization rate of raw materials is improved by 40 percent, the rejection rate is reduced by 15 percent, the labor efficiency is improved by 90 percent, the component strength is high, and the appearance is artistic; the boiling time is greatly shortened, the efficacy is improved, and energy is saved; the phenomenon of wood bluestain is avoided.

Description

technical field [0001] The invention relates to a production method for processing wood into arc-shaped parts, in particular to a production method for autoclaving and rapid prototyping of solid wood arc-shaped parts. Background technique [0002] In the past, the curved parts of dining chairs were produced by conventional sawing methods, and their production was curved saw sawing-milling-sanding. This craft wastes a lot of wood. The strength of the parts is low, and the sawing twill is easy to break, so the scrap rate is high, and the color difference of the parts is large and unsightly, the labor intensity is high, the production efficiency is low, and the production cost is high. At present, the curved parts of dining chairs can also be realized by cooking to soften the wood, then pressing and drying, but the cooking time is too long, generally takes 1-3 hours, and sometimes the wood also has blue stains. Contents of the invention [0003] The purpose of the invention...
