Multi-deflection bending shaping device and bending shaping method for furniture wood processing

Abstract

The invention discloses a multi-deflection bending shaping device for furniture wood processing. The device is composed of a material inlet platform, a soaking tank, a fumigation box, a heat-preservation levelling platform, a bending shaping box and a material outlet platform, the material inlet platform is provided with a first conveyer belt, a second conveyer belt is obliquely arranged in the soaking tank, a third conveyor belt and a steam spray pipe are arranged in the fumigation box, and the heat-preservation levelling platform is composed of a base seat, lifting rods and a lifting platform; the interior of the bending shaping box is connected with each first hot pressing roller through one corresponding first hydraulic rod and is connected with each second hot pressing roller through one corresponding second hydraulic rod, driven gears of the second hot pressing rollers are connected with a driving gear chain of a driving shaft, and the bending shaping box communicates with a hot air fan; and a slide groove of a bottom plate in the material outlet platform is in clamp connection with a T-shaped supporting foot of a motor, and the motor is connected with a horizontal push rod. The device provided by the invention realizes a bending shaping method of soaking, steam fumigation, low-pressure levelling, repeated hot roll bending and repeated hot roll shaping, is suitable for wood with different deflection, and has high bending and shaping efficiency, and high accuracy, and the shaped wood is not easy to deform.

Description

technical field [0001] The invention relates to the technical field of furniture and processing equipment thereof, in particular to a multi-deflection bending and shaping device and a bending and shaping method for furniture wood processing. Background technique [0002] With the progress of the times and the substantial improvement of the economic level, people pay more and more attention to the shape of furniture. In furniture design, curved panels and special-shaped panels determine the level of the design, but the existing curved panels mainly use The way of gluing or mortise and tenon jointing is very inconvenient to process, and only a few parts use wood bending process. [0003] The bending of wood generally needs to go through the process of softening, bending, shaping, and drying. Softening improves the plasticity of wood and increases the moisture content of wood. Drying is to remove excess water on the surface and inside of wood to make wood anti-corrosion and dur...

Problems solved by technology

[0005] Obviously, the existing wood bending and shaping methods require cutting and planing during the processing process, and the pressure is not easy to control during the processing process, and it is easy to waste materials, so it has not been widely promoted; at the same time, different radians of the board need different Mold, and the setting effect is poor. After the board comes out of the mold, it is easy to recover the deflection phenomenon. Therefore, this method is only limited to a few woods such as pine and fir. In the process of woodworking furniture, it is generally necessary to increase the supporting structure to stabilize the curvature of the wood. , far below the market demand
