Embodiment example 1

[0017] Beech timber bending parts manufacturing method:

[0018] (1) Material selection and wool processing: Beech wood is selected as the processing material. Its wood is compact and heavy, its wood grain is fine and straight, and its air-dry density is 0.79g / cm3. Choose beech boards without defects such as decay, wheel cracks, twill grains, sandwiches, and large knots, and process them into vertical straight-grain squares with a specification (length×width×thickness) of 300mm*30mm*40mm. Plan the surface of the square to eliminate the saw marks on the surface, and control the moisture content of the wool to 30%.

[0019] (2) Microwave heating method softening treatment: place the square material in a microwave heating device, the microwave frequency is 2450MHz, the treatment time is 5min, and the core temperature is controlled at 120°C.

[0020] (3) Bending forming: The square material softened by microwave heating is placed in a hot press with a bending mold at 120°C and fi...

Embodiment 1

[0023] The beech curved parts made by the method described in Example 1 have high structural strength and good shape and dimensional stability. Compared with conventional bending methods, the optimized bending process has a greatly reduced rebound rate, generally lower than 1%, and the bending The processing performance of the parts is good, and the yield of finished products is obviously improved. Compared with the existing bending process, the process cycle is shortened by more than 99%, the demand for molds is greatly saved, and the production cost is greatly reduced.

Embodiment example 2

[0025] Manufacturing method of curved parts of Mandshurica Fraxinus square material:

[0026] (1) Material selection and wool processing: Mandshurica mandshurica is selected as the processing material, the material is slightly hard, the wood grain is clear and beautiful, and the air-dry density is 0.67g / cm3. Select plates free of defects such as decay, wheel cracks, twill lines, sandwiches, and large knots, and process them into vertical straight-grain squares with a specification (length×width×thickness) of 200mm*20mm*15mm. The surface planing of the square material eliminates the saw marks on the surface, and the moisture content of the wool is controlled at 25%.

[0027] (2) Microwave heating method softening treatment: place the square material in a microwave heating device, the microwave frequency is 960MHz, the treatment time is 1min, and the core temperature is controlled at 110°C.

[0028] (3) Bending forming: The square material softened by microwave heating is place...

Abstract

The invention provides a manufacturing method of solid wood furniture bent parts. The method includes the following steps that firstly, material varieties are selected, and raw materials are machined; secondly, microwave heating softening treatment is performed; thirdly, bending and forming are performed; fourthly, drying and shaping are performed; fifthly, cooling is performed. The manufacturing method can replace a common cooking softening technology and a kiln drying shaping technology, production technology time is shortened, and production efficiency is improved; the springback rate of bend wood is reduced through a microwave heating softening method, and the bending quality of manufactured products is improved; no waste liquid is generated in the production process, and environmental friendliness is facilitated in the production process; the production period is short, production cost is low, and economic benefits can be increased easily.

Description

technical field [0001] The invention relates to the fields of wood processing and furniture manufacturing, in particular to a method for manufacturing solid wood curved furniture parts. Background technique [0002] Solid wood furniture is natural and environmentally friendly. Its natural and original wood grain, delicate feel and mild color make it used in various furniture, office facilities and decorative items. However, with the continuous improvement of people's consumption level and aesthetics, the requirements for the use function and shape of solid wood furniture are getting higher and higher. The emergence of curved wood meets the needs of the use and styling of solid wood furniture, so more and more curved components have replaced linear components, and the corresponding production technology has emerged as the times require. The traditional production methods of bent wood are mechanical processing and chemical processing, but there are problems of waste of raw ma...
