A kind of lamination thermal curing method of wood fiber special-shaped parts

Abstract

A wood fiber special shaped workpiece laminated thermal fixation method belongs to the technical field of wood material deep processing. The method comprises the steps of drying, layering measuring, front surface layer cold pressing, inverse surface cold pressing, bonding for the front surface layer and the inverse surface layer, and hot-pressing and the like. The method can manufacture wood fiber furniture pieces with property not worse than that of solid wood. The method enables surface layer pattern and inverse layer body of wood fiber pre-pressing piece to be laid independently, and cold-pressing molded separately and then hot-pressing molded again, so that the cold pressing thickness and the used wood fiber quantity of the surface layer patterns are reduced, the pressing difficulty is lowered, the cold pressing quality of the surface layer patterns is improved, the density and hardness of the surface layer patterns pressed meet the requirement, and the surface layer patterns are distinct and have layering.

Description

technical field [0001] The invention belongs to the technical field of deep processing of wood materials, and in particular relates to a method for manufacturing wood fiber special-shaped parts. Background technique [0002] With the progress of society and the continuous improvement of people's living standards, the consumer demand for high-end wooden furniture is also increasing. With its beautiful vision and comfortable touch, traditional solid wood furniture has an absolute advantage in high-end home consumption. However, solid wood furniture has the following problems: (1) Lack of wood resources, traditional solid wood furniture needs to consume a lot of raw wood materials, my country is currently facing a shortage of wood resources; (2) The utilization rate of logs is low, and the utilization rate of logs in solid wood furniture is only about 35%. , which further exacerbated the massive consumption and waste of wood resources; (3) The production efficiency is low, the ...

Problems solved by technology

However, solid wood furniture has the following problems: (1) Lack of wood resources, traditional solid wood furniture needs to consume a lot of raw wood materials, my country is currently facing a shortage of wood resources; (2) The utilization rate of logs is low, and the utilization rate of logs in solid wood furniture is only about 35%. , which further exacerbated the massive consumption and waste of wood resources; (3) The production efficiency is low, the production process of traditional solid wood furniture is relatively complicated, and the current production equipment cannot meet the needs of high-efficiency production, especially the high-end European-style furniture. carving to complete

Because wood fibers do not have flow filling properties, low free bulk density, and high molding compression ratio (about 50:1), the molding density of the pattern undulations is low, and the hardness and surface quality cannot meet the requirements.
