Problems solved by technology

[0004] The artificial timber resources in the south are mainly eucalyptus eucalyptus. Due to the high growth stress of eucalyptus eucalyptus logs, severe splitting and warping deformation occur during conventional sawing, which greatly reduces the yield and quality of sawn timber. It is the first major difficulty in the processing of Sufeng Eucalyptus solid wood

Embodiment 1

[0021] 1. Chord sawing: the two sides of the log are cut into boards by chord sawing, such as figure 1 .

[0022] 2. Radial sawing: through multi-blade saws, the boards are cut into wood chips by radial sawing at one time, such as figure 2 .

[0023] 3. Thickness and width of wood chips: During the sawing process, after adjustment, the thickness of the sawn wood chips is 1cm, and the width of the wood chips is 3cm, and the thickness of the wood chips cannot exceed 3cm.

Embodiment 2

[0025] 1. Chord sawing: the two sides of the log are cut into boards by chord sawing, such as figure 1 .

Abstract

The invention discloses a sawing method of a man-made intensively-managed eucalypt plantation. The sawing method specifically comprises the steps that wood is firstly subjected to chordwise sawing toform plate square materials, then the plate square materials are subjected to radial sawing to form wood chips, and the width and thickness of the wood chips are controlled within a certain range. Bymeans of the sawing method, the wood is firstly subjected to chordwise sawing to form the plate square materials, then the plate square materials are subjected to radial sawing to form the wood chips,and the width and thickness of the wood chips are controlled; splitting and bending deformation are effectively reduced, and the outturn percentage is increased; in the sawing process, the dimensionscale of the thickness and width of sawn wood chip finished products is controlled within 1:3, and the thickness of the wood chips is controlled within 3 cm; and the expansion and shrinkage stress ofthe wood chips is weakened, and converted timber bending deformation and splitting are greatly reduced.

Description

technical field [0001] The invention belongs to a wood processing method, in particular to a sawing method of plantation Eucalyptus sufeng. technical background [0002] At present, my country has achieved a fundamental change in the structure of timber resources from the use of natural forest timber to the utilization of plantation forest timber. [0003] Currently, the replacement of natural forest wood with plantation wood plays an important role in meeting the demand for solid wood products. [0004] The artificial timber resources in the south are mainly eucalyptus eucalyptus. Due to the high growth stress of eucalyptus eucalyptus logs, severe splitting and warping deformation occur during conventional sawing, which greatly reduces the yield and quality of sawn timber. It is the first major difficulty in the processing of Sufeng Eucalyptus solid wood. Contents of the invention [0005] The purpose of the present invention is to overcome the deficiencies in the prior...
