Problems solved by technology

[0002] Irregular round wood refers to the wood that is curved in length (that is, arched), or the cross-section is far from round. These woods have the disadvantages of low board yield and serious waste in the process of being processed into boards. Some It cannot even be used as a raw material for processing boards; in order to improve the utilization rate and reduce waste, the technical solution that can be adopted is to apply pressure on the bowed side to make the wood straight, which can improve the utilization rate of the wood, but such The method has the disadvantage that the wood is easy to recover and bounce back to its original shape, and the use effect is affected. This method can not solve the problem that the round wood with a large difference in cross-section and circular shape is used as a raw material for the board and further improves the utilization rate.
[0003] In order to achieve a better wood correction effect, there are other wood finishing methods that heat the wood and perform the above correction after heating. If the temperature is too high or low, the desired effect cannot be achieved.

Embodiment 1

[0027] a. Take a 2.5-meter-long, irregular cypress, place it in a heating room and heat it to 105 degrees for a period of time. The temperature inside the cypress is 85 degrees.

[0028] During the heating process of cypress wood, the internal temperature rises slowly. If the internal temperature is brought closer to 105 degrees, it will take a long time. The internal temperature can reach 85 degrees to meet the requirements of the present invention.

[0029] A log with a diameter of 20 cm can meet the requirements in 60 minutes when the surrounding environment is 300 degrees, and a log with a diameter of 25 cm can meet the requirements in 65 minutes when the surrounding environment is 300 degrees. Those in the field can easily rely on it. Master of experience, the same below.

[0030] b. Use a press to flatten the cypress in the above a, and slowly lower the temperature to room temperature, the cooling process is 60 minutes.

[0031] The pressing and flattening is pressing the arched...

Embodiment 2

[0034] a. Take a 2.5-meter long, irregular cypress, place it in the heating room and heat it to 95 degrees for a period of time. The temperature inside the cypress is 80 degrees.

[0035] b. Use a press to flatten the cypress in the above a, and slowly lower the temperature to room temperature for 70 minutes.

[0036] The cypress prepared in this embodiment can improve the utilization rate and the product has the advantages of not being easily deformed. Compared with Example 1, the recovery deformation is slight. It can be considered that the heating temperature in this embodiment is lower, but this still meets the requirements.

Embodiment 3

[0038] a. Take a 2.5-meter-long, irregular cypress, place it in a heating room and heat it to 100 degrees for a period of time. The internal temperature of the wood is 92 degrees.

[0039] b. Use a press to flatten the wood in a, and slowly lower the temperature to room temperature. The cooling process is 80 minutes.

[0040] The wood finished in this embodiment can improve the utilization rate, and the product has the advantages of not being easily deformed. In general, among Examples 1, 2, and 3, Example 3 is the best, because it can ensure the effect, and can also reduce the temperature. , To achieve the lowest cost.

Abstract

The invention relates to the technical field of wood finishing, and discloses a finishing method of wood. The finishing method comprises the following steps: a, heating the wood till the external temperature reaches 95-105 DEG C, and maintaining for a period of time, so that the temperature difference between inside and outside of the wood is not more than 20 DEG C; b, pressing and flattening the wood in step a by using a pressing machine, slowly cooling to room temperature for more than 60 min, and putting the wood in the step a in a dedicated mold, wherein the dedicated mold comprises two mold split bodies, each mold split body is of a long-strip-shaped structure with a V-shaped opening, mounting components mounted on the pressing machine are arranged at the back of the mold split bodies respectively, and the mounting components are arranged on the pressing machine when being used. The finishing method has the advantages that the log utilization rate is improved, a correction bending effect is good, the wood is unlikely to be deformed after correction, the wood does not need to be heated to an extra-high temperature and the waste is reduced.

Description

Technical field [0001] The invention relates to the technical field of wood finishing, in particular to a wood finishing method. Background technique [0002] Irregular round wood refers to wood that is curved in length (that is, arched), or that has a large difference in cross section and round shape. These woods have the disadvantages of low board yield and serious waste in the process of processing into boards. It can’t even be used as a raw material for processing boards; in order to improve the utilization rate and reduce waste, the technical solution that can be adopted is to press on the arched side to make the wood straight, which can increase the utilization rate of the wood. The method has the disadvantage that the wood is easy to recover and rebound to its original shape, and the use effect is affected. This method cannot solve the problem of using round wood with a large difference in cross section and circular shape as the raw material of the board and further improv...
