Description
Technical field
The present invention relates to wood processing field and Furniture manufacture field, particularly a kind of manufacture method of bending of solid wood furniture part and assembly.
Background technology
That solid wood furniture has is natural, the characteristic of environmental protection, and its naturally original wood grain, fine and smooth feel and gentle color and luster are applied in various furniture, office facility and adornment it. But along with improving constantly of people's level of consumption and aesthetic conceptions, more and more higher to use function and the modeling requirement of solid wood furniture. The appearance of bending-wood has met use and the moulding needs of solid wood furniture, and therefore curved member has more and more replaced linear pattern member, and corresponding production technology is also arisen at the historic moment. Traditional bending-wood production method is mechanical processing method and chemical process method, but it exists waste of raw materials and problem of environmental pollution. And now conventional hydro-thermal method is softening and though kiln drying method has solved above technological problems, but hydro-thermal method easily increases the moisture content of timber, increase drying time, production cycle is longer, large to bending mould demand, be unfavorable for lowering production cost, and in BENDING PROCESS, easily cause wood failure, produce waste product.
Chinese patent literature CN104802247A discloses a kind of mahogany furniture curved member bending of solid wood process, and its special character is: comprise poach or gas steaming processing, mold bending shaping, dryness finalization etc. Poach is softening, and water temperature is controlled at 70-80 DEG C, and the softening time is that the every thick 20mm of timber is 20-30min; Gas steams softening, and vapor (steam) temperature is controlled at 105-115 DEG C, and the softening time is that the every thick 20mm of timber is 30-40min. Mold bending is shaped, adopt manual fixture or the Qu Muji mould pressurizing of being fitted to bend to the shape of requirement, when shaping, in timber length direction, adopt metal steel band and facing stop and add timber wedge to make square bar location, prevent from outside square bar that Extrude Face is broken to lose with inboard compression face to crumple damage. Dryness finalization, adopts steam seasoning, and baking temperature is 40-60 DEG C, and the time is 48-72h, and after dryness finalization, moisture content is 10% left and right. Such scheme can substitute the tradition line saw processing method processed generally adopting at present, promotes the production technology level of mahogany furniture curve part, simplifies production craft step, improves timber utilization rate, strengthens the intensity of parts. The shortcomings such as but its processing method has long processing time, mould demand is large, bool rebound degree height; In addition, after being carried out that poach is softening and processed, timber can produce sewage, because redwood moisture content is high, and cycle length and easily produce waste product in the time be dried and shape.
Summary of the invention
The invention provides a kind of wood-bending processing with short production cycle, yield rate is high, more energy-conserving and environment-protectiveThe manufacture method of the bending parts of solid wood furniture, and solved that the product rebound degree of currently available technology technique is high, the shortcoming such as need to dispose of sewage.
Technical solution of the present invention: the bending method of the bending parts of solid wood furniture, comprises the steps:
(1) assortment is selected and woollen processing: select seeds according to the radius of curvature of the thickness of bending parts and requirement, require the texture of timber perfectly straight, gradient is less than 10 °. Moisture content is 18% ~ 35%, lumber thickness 15mm ~ 40mm;
(2) microwave heating method is softening processes: the solid wood square bar after preferred is placed in to microwave heating equipment and softens processing, microwave frequency is 960MHz ~ 2450MHz, and the processing time is 1min ~ 5min, controls 100 DEG C ~ 120 DEG C of timber core temperature;
(3) bending forming: the timber after softening is positioned in 100 DEG C ~ 120 DEG C hot presses with bending mould fixing, wood-bending is become to desired shape;
(4) microwave drying sizing: the timber after bending and shaper are inserted to microwave heating system and carry out dryness finalization. Microwave frequency is 960MHz ~ 2450MHz, and the processing time is 8min ~ 12min, and moisture content is dried to 8% ~ 12%;
(5) cooling: the timber of dryness finalization to be cooled to temperature under field conditions (factors) lower than after 50 DEG C, to remove mould, make bentwood furniture parts.
Effect of the present invention is:
(1) owing to adopting, microwave heating method is softening to be processed, produce without waste liquid in process of production, so it is many to produce sewage while having solved existing hydrothermal treatment consists, softening long technical problem of cycle, thereby make the more energy-conserving and environment-protective of method of bending solid wood, be conducive to increase economic efficiency.
(2) owing to adopting, microwave heating method is softening to be processed, and moisture content is 18% ~ 35%, compared with prior art, can significantly shorten drying time, enhances productivity; Because moisture content is low, overcome conventional art high technical problem of percent defective in the time carrying out dryness finalization in addition, thereby improved the bending quality of goods.
(3) owing to adopting microwave heating system to carry out dryness finalization, overcome the existing conventional drying sizing production cycle long, the technical problem of the easy resilience of bending part, makes the furniture bending part rebound degree that obtains low, and yield rate is high.
