A kind of preparation technology of half tenon and mortise structure at the joint of wood products

Abstract

The invention discloses a preparation process for a half-mortise and tenon structure at the joint of wood products, which belongs to the technical field of tenon and tenon preparation. It discloses a process for preparing a half-mortise and tenon structure at the joint of wood products. The setting can effectively cut off and polish the wood shavings on the inner wall of the mortise, thereby effectively improving the flatness of the inner wall of the mortise, and can also effectively reduce the difficulty of grinding the inner wall of the mortise, thereby effectively improving the half-mortise. The production efficiency is high. At the same time, the process of pressurized friction ball grinding is also a process of compacting wood shavings, so that the gap between the remaining fine wood shavings and the inner wall of the mortise after grinding is smaller. At the same time, it can be used to help level the glue layer Effectively increase the flatness of the inner wall of the mortise, and at the same time effectively improve the overall hardness and strength of the inner wall of the mortise, thereby effectively improving the connection tightness between the mortise and the mortise, making it difficult for the half mortise to loosen, and effectively extending the service life.

Description

technical field [0001] The invention relates to the technical field of mortise and tenon preparation, and more specifically, relates to a process for preparing a half mortise and tenon structure at the joint of wood products. Background technique [0002] Mortise and tenon (sǔn mǎo) is the main structural method of ancient Chinese buildings, furniture and other appliances. It is a connection method that uses concave and convex parts on two components. The protruding part is called tenon (or tenon); the concave part is called tenon (or tenon, tenon and groove). Wood products are usually connected by tenon and tenon. Its characteristic is that no nails are used on objects, and mortise and tenon are used to reinforce objects, which reflects ancient Chinese culture and wisdom. [0003] Dozens of different "mortise and tenon" are classified according to their structure and can be roughly divided into three types: [0004] One type is mainly used for the joining of surfaces, and...

Problems solved by technology

[0007] The joints on the side of the picture frame mostly adopt the half-tenon connection method. Compared with the through-tenon, the mortise and tenon holes are not pierced, and the straight tenon is not exposed, so the tenon and tongue are generally two-thirds of the through-tenon. Since the mortise is not cut through, a lot of uneven wood shavings will remain on the inner wall during the preparation process, especially the inner wall facing the mouth of the mortise and mortise is more rough, resulting in the gap between the inner walls of the mortise and tenon after the half-mortise connection in the later stage. The connection is not tight enough, and there are gaps, which makes the connection on the side of the picture frame easy to loosen, which affects the service life of the picture frame
