Watches and method for their production

Abstract

The invention relates to a bamboo straight nail row. All bamboo nails are longitudinally arranged in parallelism along the fiber direction of the bamboo and are in a row; the head (1) of the nail is in wedge-shape and the section area of the tail (3) of the nail is larger than the section area of the nail body (2); the whole nail is the laminated structure with interval of a glue layer (4) and a thin bamboo piece layer (5), with the density more than 1000kg / m(SUP)3( / SUP). The manufacture of the bamboo straight nail row comprises the steps of production of thin bamboo piece, drying in kiln, glue dipping or glue coating on two surfaces, re-drying, blanking in orientation, hot pressing by press, cutting according to the length requirement of the nail, milling process into the nail row. The invention can replace general metal nail row; in the application of decoration engineering, vine furniture and wood products, the invention has the advantages of low cost, no rust, large density, high strength, self-control to the depth in the wood, nailing the wood with high density, etc. compared with the existing bamboo wood nails.

Description

technical field [0001] The invention relates to a bamboo straight row nail used in decoration engineering, rattan furniture and wood products and a manufacturing method thereof. Background technique [0002] CN2448980 and CN1289898 disclose Mr. Zhao Hongjiu's "a kind of bamboo and wood straight row nail" patent technology respectively. A number of chamfering grooves are evenly and symmetrically opened, and a nail blade with a certain slope is ground up and down on any long side of the bamboo wood chip." The material selection of the bamboo wood straight row nails requires the same bamboo wood as the surface board . The deficiencies of the above-mentioned prior art have four points: the one, the straight row of bamboo nails is made of bamboo veneer, and the strength is not enough, and the success rate of ideal penetration into the wood is not large enough; Bamboo is straight and straight, so it is very difficult to nail into wood. Third, the material selection must be consi...

AI Technical Summary

Problems solved by technology

The deficiencies of the above-mentioned prior art have four points: the one, the straight row of bamboo nails is made of bamboo veneer, and the strength is not enough, and the success rate of ideal penetration into the wood is not large enough; Bamboo is straight and straight, so it is very difficult to nail into wood. Third, the material selection must be consistent with that of the surface board. The cross-section of the nail body is the same, and the penetration depth of the nail cannot be controlled automatically

In short, the existing bamboo and wood straight row nails have the disadvantages of insufficient strength, high-density wood is difficult to nail or poor wood penetration, and the design concept neglects the function of automatic control of the nail depth
