Problems solved by technology

However, the use of iron nails increases troubles for the secondary use of timber structures
In addition, long-term use of iron nails will also have problems such as rust and other problems that reduce its performance, and the places where iron nails have been nailed have poor secondary processing performance, etc.
These problems can be completely solved by using bamboo nails that can achieve the performance of iron nails. At present, the main manufacturing method of bamboo nails is to directly make bamboo nails into nail shapes. The durability of bamboo nails produced in this way is not high and cannot be used for a long time.

Abstract

The invention discloses an engineering bamboo nail manufacturing method. The engineering bamboo nail manufacturing method comprises the following steps of: step 01. cutting bamboos into bamboo chip units, and processing the bamboo chip units into round rod-shaped bamboo rods by using a wire drawing machine; step S02. carrying out ultraviolet light treatment and drying treatment on the bamboo rodsobtained in the step S01; step S03. impregnating the dried bamboo rods obtained in the step S02 in resin; step S04. cutting off the bamboo rods impregnated in the step S03 to form bamboo nails; step S05. sharpening the bamboo nails in the step S04; and step S06. roughening the roots of the bamboo nails in step S05. The invention also discloses engineering bamboo nail processing equipment. The engineering bamboo nail manufacturing method and the engineering bamboo nail processing equipment have the advantages that the hardness and toughness of the processed engineering bamboo nails are obviously improved, the processed engineering bamboo nails can be used for a long term, is unlikely to corrode and is long in life cycle, and the durability of the engineering bamboo nail is remarkably improved.

Description

technical field [0001] The invention relates to a method for manufacturing engineering bamboo nails and processing equipment thereof, belonging to the field of wood structures. Background technique [0002] With the rapid development of wood structure profession in recent years, the consumption level of wood structure products is increasing year by year. When connecting wood structure components, engineering nails are usually required. However, the use of iron nails increases troubles for the secondary use of wood structural materials. In addition, long-term use of iron nails will also have problems such as rust and other problems that reduce its performance, and the places where iron nails have been nailed have poor secondary processing performance. These problems can be completely solved by bamboo nails that can achieve the performance of iron nails. The main manufacturing method of bamboo nails is to directly make bamboo into nails. The durability of bamboo nails produce...
