Cold pressing shock excitation forming and thermosetting method for wood fiber special-shaped workpiece

Abstract

The invention discloses a cold pressing shock excitation forming and thermosetting method for a wood fiber special-shaped workpiece, and belongs to the technical field of deep processing on wood materials. The cold pressing shock excitation forming and thermosetting method comprises five steps of drying, material stirring and gluing, metering, cold pressing shock excitation and microwave thermosetting, so that wood fiber furniture pieces which are not inferior to solid wood in quality can be manufactured. Compared with the prior art, a cold pressing shock excitation forming technology is adopted, so that a hot pressing procedure is omitted, the production time is shortened, and the production efficiency is increased to a large extent; meanwhile, the requirement on moisture content of wood fiber is increased and broadened, and the wood fiber has certain scalability in a forming die through shock excitation, thus a special-shaped part of a formed product is fully filled, the internal density of the formed product is uniform, and the surface of the formed product is smooth and dense; finally, since the cold pressing shock excitation forming and microwave thermosetting technology adopts a plastic die but not a traditional iron die, dies and the manufacturing cost of the dies are greatly reduced.

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...

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

The disadvantage of the existing hot-press forming process of wood fiber special-shaped parts is that steel molds are used to withstand high temperature and high pressure to manufacture parts, and the processing cycle is long and expensive. The input and depreciation expenses not only exploit the production profit, but also limit the large-scale development of the industry
