A kind of equal pressure forming method of wood fiber molded special-shaped parts

Abstract

The invention discloses an equal-pressure forming method of wood fiber molded special-shaped parts and belongs to the technical field of deep processing of wood materials. The equal-pressure forming method comprises the steps of drying, metering, feeding, pre-pressing by an elastic punch and hot pressing by a rigid punch and can be used for manufacturing wood fiber furniture parts which are not inferior to solid wood furniture parts. Compared with the prior art, the punch generates equal-pressure deformation by the method by using the characteristic that the high-strength elastic material is incompressible in volume but deformable in volume under the pressed state, so that the punch is equal in positive compression force and lateral compression force, thereby enabling wood fibers of compactly filled parts at local corner in a mold to be extruded to uncompacted parts in a filling mold; the wood fiber furniture parts are equal in density; the forming effect of the wood fiber furniture parts is improved.

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, on the one hand greatly increased labor costs, on the other hand lead to extended manufacturing cycle

The molding process of wood fiber special-shaped parts is still in the early stage of research. The existing hot-press molding method of wood fiber special-shaped parts, due to its poor filling and fluidity, the local surface of the product will have quality defects such as softness and corner filling.
