Description

A inner diameter processing device of timber}

The present invention relates to an inner diameter processing apparatus of wood, and more particularly, to a processing portion of the inner diameter processing apparatus of the wood to configure not only the hole drilling, but also the expansion of the inner diameter and curved surface processing, the inner diameter processing of the wood The present invention relates to an inner diameter processing apparatus for wood that enhances the competitiveness of a product to improve the serviceability of wood by adjusting to a level required by a user.

Recently, in accordance with the trend of eco-friendliness or well-being, facilities made of nature-friendly wood are being deployed in jade and outdoor landscaping spaces.

However, the facilities made of wood are more decayed than steel or stone in preservation and maintenance, resulting in cracking of the surface of the wood.

Therefore, the wood needs to be preserved to obtain proper surface protection and durability, and especially for wood used in contact with soil, the durability of the wood is easily weakened, so the preservation is particularly necessary.

A method for this antiseptic treatment is disclosed as follows.

Conventional antiseptic treatment, ① pre-drying step of natural drying the bar of long wood at a water content of 18% to 23%, ② exhaust gas exhaust step to extract the maximum internal air in the vacuum state of 740mmHg, ③ main medicine tube Filling the preservative liquid in the chemical liquid filling step to immerse the wood in this chemical liquid, ④ Pressurizing step to push the antiseptic liquid into the wood for 4 to 6 hours at a pressure of 5 to 29kg / cm2, ⑤ Preservation under vacuum of 650 to 740mmHg The post-treatment step of recovering chemicals and recovering excess chemicals on the surface of the wood, ⑥ Post-drying step of curing for 3 weeks at room temperature and artificial curing at 60 ℃ for 3 weeks to settle the chemicals invaded by wood, and ⑦ Inspection step have.

However, in the chemical liquid filling step and the pressurizing step, the wood penetration effect of the antiseptic liquid is insufficient, or due to the characteristics of the wood, cracking occurs on the surface of the wood due to the difference in drying speed between the inside and the outside, thereby greatly maintaining and maintaining the installed facilities. It is occurring.

Therefore, it is necessary to form a longitudinal through hole in the rod of the long wood to maximize the wood penetration effect of the antiseptic solution, and to reduce the difference in drying speed.

Although it is usually carried out by a known drill to form a longitudinal through hole in the rod of such a long wood, this known drill is possible to form a short through hole, but not to form a long through hole. .

The reason for this is that as the drill hole becomes deeper than the known drill shape, the cutting chips generated by the drill process cannot be easily pulled out to the outside, resulting in damage to the workpiece or the drill. Because.

1 is a front view of an apparatus for forming a hollow hole in a rod of a conventional wood, referring to this, a wood hole mill for solving the above problems is domestic patent No. 549713 (name: long rod of wood Preservation method of the wood hole of the method and the device for forming a hollow hole in the rod of wood) Base portion 10, the guide rail 20 is fixedly mounted on the base end side of the base portion 10 , A workpiece support 30 fixedly mounted at the front end side of the base portion 10, and a drilling device 40 mounted on the guide rail 20 to be manually movable in a known manner.
