Abstract

A method for making radially cut wooden material includes sawing log into hexagonal or octagonal material, sawing it into 6-8 triangular materials, removing center to become trapeziums or not, binding them together to obtain square materials, and adhering them together to obtain pure radially cut material with natural grains. Its advantages are high productivity and production in large batches.

Description

A kind of manufacture method of quarter sawing material

The present invention relates to a kind of manufacture method of pure wood based panel: mainly be to combine with quarter sawing by gummed to process the method for pure wooden boards, now in the building material industry, the processing of products such as case goods's plate, wall slab, big specification floor is that log scale is sawn into several laths, and gluing was bonding again after every block of lath was planed one by one forms.Sometimes need just can finish for tens times even tens times, and the specification of lath is more little, the number of times that repeats to process is just many more, and loss is big more, and production efficiency is descended significantly, can not adapt to requirements of large-scale production.

Very low with commonsense method processing log, the volume recovery of becoming a useful person, drying is scraped to become a useful person and is accounted for its log volume below 50%, this is because of being subjected to log saw to cut open the restriction that squarely or rectangle are become a useful person, adopt the actual volume recovery of commonsense method to depend on log diameter or curvature, even but the saw that adopts electronic computer to control, average volume recovery also has only 50% of log volume, the volume recovery of undersized log is lower, common moist sawn timber adopts the thin belt saws saw lumber, volume recovery reaches as high as 69%, (garden saw and gang sawing volume recovery are 51-61%).

Adopt many methods in the past, production of volume recovery veneer and lamination method that attempt increases log are a kind of successful examples, it can improve volume recovery and reach 65%, log is peeled into a volume veneer in veneer production, it can lamination become various woodworks such as glued board, and it is different from the characteristic that the monoblock sawing is become a useful person.

The object of the present invention is achieved like this: utilize the saw lumber saw according to different requirements, log is processed into difform section bar, the cross section of this section bar is hexagon or octagon, also can remove the medulla part of log, after the section bar drying, planing into desired specification with planer puts section bar again by necessarily putting in order, on faying face, be coated with the integrated timber special glue, be pressed into square type laminated wood, by the sideline laminated wood is processed into the required square bar of wanting again, square bar is composed in certain sequence the pure quarter sawing material of natural wood grain.

The present invention has good effect: bonding process is easy, whole process only needs gummed 1-2 time, because section bar has been synthesized big laminated wood and can have avoided repeatedly repeating process, improved production efficiency, thereby be more suitable for the production in enormous quantities of product, the product that processes with this kind processing method belongs to the product of the native texture pattern of pure quarter sawing material, and is indeformable, can be widely used in the construction and decoration furniture.

Describe the present invention in detail below in conjunction with accompanying drawing.

Utilize the saw lumber saw log (seeing Fig. 1-2), be processed into difform section bar by the difference requirement, the horizontal face that connects of this section bar is a hexagon, octagon, hexagon octagon material is resolved into triangle or trapezoidally (sees Fig. 3 with former saw, 4,5,6) after the section bar drying, dig into required specification with planer, again section bar is put in certain sequence, being coated with the integrated timber special glue on faying face is pressed into rectangular gluing wood and (sees Fig. 7,8), utilize multiple blade saw to resolve into square bar, thickness is decided on product, arrange in certain sequence then, the strip square bar is become certain specification and has the quarter sawing sheet material (see figure 9) of multiple quarter sawing native texture with different size with same integrated timber splicing, and whole process overview is seen Figure 10.

Claims (2)

1, a kind of manufacture method of quarter sawing material: it is characterized in that, utilize the saw lumber saw log to be processed into difform section bar according to different requirements, it is 6 square and 8 square that this section bar horizontal connects face, be processed into triangle or trapezoidal with the garden saw again, remove the medulla part of log or the heart part of not emedullating simultaneously, after the section bar drying, plane into desired triangle or trapezoidal with planer again triangle or trapezoidally put in certain sequence, on cemented surface, be coated with the integrated timber special glue and be pressed into rectangular gluing wood, utilize former saw saw to cut open a side of laminated wood, saw cuts rectangular square bar, and saw cuts open thickness to be decided by the thickness of product.

2, the processing method according to the described a kind of quarter sawing material of claim is characterized in that: after section bar gummed and saw cut open and process the strip plank, according to the edger-grain pattern on the elongated plates, in certain sequence the strip plank with the wide one-tenth certain specification of same integrated timber splicing with have the big sheet material of native texture of multiple different size quarter sawing material.
