Embodiment 1

[0033] The stile material adopts a three-layer superimposed glued structure along the grain. The upper and lower surfaces are made of 3mm thick sawn solid wood veneer, the middle layer is made of 34.5mm thick solid wood knuckles, and the two sides are respectively spliced ​​with solid wood edge banding. The surface quality of the solid wood knuckles has no other material requirements except rotten insect holes and holes.

[0034] The door stile surface board is selected and added according to the size of the door stile, and a 20mm machining allowance is reserved in the length direction, and a 5mm machining allowance is reserved in the width direction; use a horizontal band saw or a frame saw to decompose it into 4mm thin plates, and use a fixed Thick sander sands the surface to 3mm.

[0035] The door stile core material is made of inferior quality materials or leftover materials into 36mm thick knuckle boards, which are sawed longitudinally to the design size; the two sides of...

Abstract

The invention discloses a cracking-preventing solid door production process and relates to the field of building materials. The cracking-preventing solid door production process comprises stile manufacturing, door paneling manufacturing, door leaf assembling and door leaf sanding, painting and packaging, wherein a three-layer rift grain overlaying glued structure is adopted to the stile material, a three-layer square crossing overlaying glued structure is adopted to door panelings, and meanwhile the construction process is improved. The process solves the problem that a solid door is prone to cracking and deformation.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a production process for anti-cracking solid wood doors. Background technique [0002] Since the 1950s, China's wooden door industry has developed rapidly. In the 1980s, while learning from different solid wood door styles and advanced production technologies in various countries, people continued to explore traditional skills, combined with their own national conditions and folk customs, and gradually formed a new generation of wooden door styles. The years are like songs, time flies, and the history has developed to this day, and the manufacturing process of wooden doors has become relatively perfect. However, most solid wood doors are meter-gauge wood, and the wood hardness is relatively high. Most of the wood is hardwood, which has a large shrinkage rate and is easy to crack. At the same time, the size of solid wood door parts is relatively large, and the high quality requ...
