Door panel and machining process thereof

Abstract

The invention relates to a door panel and a machining process thereof, and belongs to the technical field of door panels and manufacturing processes thereof. The door panel comprises a middle transverse line independent-layer or transverse and longitudinal line multi-layer base plate (1); an upper edge-banding plate (3) and a lower edge-banding plate (5) are glued at the upper end and the lower end of the base plate (1) in the length direction respectively; the middle parts of the upper edge-banding plate (3) and the lower edge-banding plate (5) are provided with transverse lines, and both faces of each of the upper edge-banding plate (3) and the lower edge-banding plate (5) are provided longitudinal lines; a longitudinal line left edge-banding plate (2) and a longitudinal line right edge-banding plate (8) are glued on the left side and the right side of the base plate (1) in the width direction respectively; the base plate (1), the upper edge-banding plate (3), the lower edge-bandingplate (5), the left edge-banding plate (2) and the right edge-banding plate (8) are integrated on the same plane; and longitudinal line panels (4) are bonded and pressed on the front face and the rear face of the integrated structure. The door panel is hard to bend, deform, crack, contract in dry weather and expand in wet environment, and has high impact bearing capacity.

Description

technical field [0001] The invention relates to a door core board and a processing technology thereof, and belongs to the technical field of door core boards and the manufacturing technology thereof. Background technique [0002] Wood density is divided into high density (mahogany 1000kg / m 3 above), medium density (800kg / m 3 around), low density (500kg / m 3 Within) three categories, because the density of wood is different, the absorption of moisture in the air is different, the expansion and contraction are different, the degree of cracking is different, and the degree of deformation is also different. This is the nature and characteristics of wood itself. Due to the different wood and different characteristics, coupled with traditional historical craftsmanship, there are generally four major disadvantages in the production of pure solid wood doors and furniture: 1. Easy to deform and bend; 2. Easy to crack; The water content rises; 4. The ability to withstand impact is p...
