Abstract
The invention discloses a unit arc bamboo splint flattening and shaping method. The method comprises the following steps of: removing internal and external joints after splitting moso bamboo at a fixed length to obtain a unit arc bamboo splint; softening the unit arc bamboo splint, wherein the unit arc bamboo splint is first softened to 90-110 degrees in a softening treatment pool for 20-22 hours; flattening the unit arc bamboo splint in a segmental way; feeding the unit bamboo splint in a treatment box with constant temperature of 20-40 degrees by using upper and lower press rolls; applying a certain pressure to the unit bamboo splint by using the upper and lower press rolls in the feeding process so as to flatten the unit bamboo splint; spraying cold water to the flattened unit bamboo splint so as to carry out cold treatment and shaping so that the overall dimension of the bamboo splint is stable; and finally, thickening and trimming the unit bamboo splint to obtain a bamboo splint with desired size. The unit arc bamboo splint flattening and shaping method disclosed by the invention has the advantages of simplified operation process and high working efficiency; and the machining process from the softened unit bamboo splint to the finished product is one-step molding.
Description
Technical field
The present invention relates to a kind of unit arc bamboo bar and flatten method for shaping.
Background technology
At present, the bamboo board that uses on the market is that the unit bamboo bar after hacking is first through force plane (removing surf green, bamboo spring) basically; Adjustable cast iron planes is made perfectly straight unit bamboo a tree, used in making timber for boats bar, and its work efficiency is low, and volume recovery is low; Volume recovery is basically between 20%-30%; And after using arc bamboo bar modular system, its volume recovery improves about 20% between 40%-50%.
Summary of the invention
The present invention overcomes the low shortcoming of bamboo wood volume recovery in process, provide a kind of unit arc bamboo bar to flatten method for shaping bamboo wood is efficiently utilized, its volume recovery between 40%-50%, one-shot forming, its process is easy and simple to handle.
Technical solution problem of the present invention provides following scheme:
A kind of unit arc bamboo bar flattens method for shaping, it is characterized in that:
(1) at first mao bamboon is carried out fixed length, hacks after, remove interior acromere again, obtain unit arc bamboo bar;
(2) again unit arc bamboo bar is softened processing, said unit arc bamboo bar carries out earlier 20-22 hour 90 spending to the softening processing of 110 degree in softening treatment pond hot water;
(3) carry out segmented again and flatten, unit bamboo bar is spent in the treatment box of 40 degree at constant temperature 20 and is used the lower compression roller feeding, and lower compression roller imposes certain pressure and flattens in the feeding process; Unit bamboo bar after the flattening carries out the cold treatment typing through spraying cold water, makes the overall dimensions of bamboo bar stable;
(4) at last unit bamboo bar is obtained the bamboo bar of required size through thicknesser and deburring.
Said softening method can also for: unit arc bamboo bar is placed in 70 ℃ of-80 ℃ of treatment ponds of water temperature, perhaps carries out the hot mastication that high-temperature steam spray steamed 20-22 hour and handle.
The beneficial effect of equipment of the present invention and process is:
(1) can solve because of unit arc bamboo bar loss in process is big, the problem that volume recovery is low can make bamboo wood efficiently utilized.
(2) operating process is simplified, and bamboo bar softening back in unit is one-shot forming to half-finished process, and work efficiency is high.
(3) can the physicochemical property of bamboo wood not exerted an influence.
The specific embodiment
A kind of unit arc bamboo bar flattens method for shaping, it is characterized in that:
A kind of unit arc bamboo bar flattens method for shaping, it is characterized in that:
(1) at first mao bamboon is carried out fixed length, hacks after, remove interior acromere again, obtain unit arc bamboo bar;
(2) again unit arc bamboo bar is softened processing, said unit arc bamboo bar carries out earlier 20-22 hour 90 spending to the softening processing of 110 degree in softening 70 ℃ of-80 ℃ of hot water of treatment pond;
(3) carry out segmented again and flatten, unit bamboo bar is spent in the treatment box of 40 degree at constant temperature 20 and is used the lower compression roller feeding, and lower compression roller imposes certain pressure and flattens in the feeding process; Unit bamboo bar after the flattening carries out the cold treatment typing through spraying cold water, makes the overall dimensions of bamboo bar stable;
(4) at last unit bamboo bar is obtained the bamboo bar of required size through thicknesser and deburring.
Said softening method can also be handled 20-22 hour for carrying out 20-22 hour hot mastication of high-temperature steam spray steaming.
Claims (2)
1. a unit arc bamboo bar flattens method for shaping, it is characterized in that:
(1) at first mao bamboon is carried out fixed length, hacks after, remove interior acromere again, obtain unit arc bamboo bar;
(2) again unit arc bamboo bar is softened processing, said unit arc bamboo bar carries out earlier 20-22 hour 90 spending to the softening processing of 110 degree in softening treatment pond hot water;
(3) carry out segmented again and flatten, unit bamboo bar is spent in the treatment box of 40 degree at constant temperature 20 and is used the lower compression roller feeding, and lower compression roller imposes certain pressure and flattens in the feeding process; Unit bamboo bar after the flattening carries out the cold treatment typing through spraying cold water, makes the overall dimensions of bamboo bar stable;
(4) at last unit bamboo bar is obtained the bamboo bar of required size through thicknesser and deburring.
2. flatten method for shaping according to the said unit of claim 1 arc bamboo bar; It is characterized in that: said softening method can also for: unit arc bamboo bar is placed in 70 ℃ of-80 ℃ of treatment ponds of water temperature, perhaps carries out the hot mastication that high-temperature steam spray steamed 20-22 hour and handle.
