Description
技术领域 technical field
本发明涉及一种天然实木木材弯曲前处理预压缩设备及其压缩方法。 The invention relates to a pre-treatment pre-compression device for natural solid wood and a compression method thereof.
背景技术 Background technique
实木弯曲是高附加值木材加工工艺之一，方法有汽蒸弯曲、微波加热弯曲、化学处理(如氨处理)弯曲等等。木材是多孔性材料，例如单位体积水曲柳中，大约40%是实体木料，而其余的60%则是充满空气的孔道。湿木材加热至100度即变得柔软可弯，弯曲面外缘可伸长2%左右纤维不断裂，而内缘可压缩35%左右纤维不压溃。 Solid wood bending is one of the high value-added wood processing techniques, including steam bending, microwave heating bending, chemical treatment (such as ammonia treatment) bending and so on. Wood is a porous material. For example, about 40% of the unit volume of Mandshurica mandshurica is solid wood, while the remaining 60% are pores filled with air. When wet wood is heated to 100 degrees, it becomes soft and bendable. The outer edge of the curved surface can be stretched by about 2% without breaking the fibers, while the inner edge can be compressed by about 35% without crushing the fibers.
众所周知传统的汽蒸法弯曲家具零件，需在弯曲面外缘置一钢带以将中性面外移防止外层纤维断裂，并必须抓紧时间趁热弯曲。因此构想一种新的压缩弯曲方法，将湿的天然实木木材或刨光材加热软化，再顺纤维方向压缩至原有长度的80%左右，然后卸载弯曲、热弯冷弯均可，对于多数树种的木材无需用钢带，有足够的时间弯成各种式样的形状，单面弯曲、多面弯曲、弯成“S”形、弯成螺线形等等均可。 As we all know, the traditional steaming method of bending furniture parts needs to place a steel belt on the outer edge of the bending surface to move the neutral plane outward to prevent the outer fiber from breaking, and it must be bent while it is hot. Therefore, a new compression bending method is conceived, heating and softening the wet natural solid wood or planed wood, and then compressing it along the fiber direction to about 80% of the original length, and then unloading bending, hot bending and cold bending can be used, for most There is no need to use steel strips for the wood of tree species, and there is enough time to bend into various shapes, such as single-sided bending, multi-sided bending, "S" shape, spiral shape, etc.

The side pressure cylinder group 3 and the main top cylinder 7, the top pressure cylinder 1 is connected with the top pressure plate 10, the side pressure cylinder group 3 is connected with the side pressure plate 9, wherein the top pressure plate 10 and the side pressure plate 9 are steel plates with good strength, the top pressure cylinder The strokes of the pressure cylinder 1 and the side pressure cylinder are controlled by two up and down stroke switches 2 and 4, the descending and rising of the top pressure plate 10, the side pressure cylinder group 3 and the side pressure plate 9 are completed by the top pressure cylinder 1, and the main top cylinder 7 It is connected with one end of the spring, and the other end of the spring is connected with the spring seat 8. The purpose is to prevent the main top oil cylinder 7 from directly contacting the wood and causing damage to the wood. The power of the hydraulic control system is provided by the hydraulic pumps 5,6.
其中，顶压油缸1与顶压板10相连，侧压油缸组3与侧压板9相连，其中连接方式为螺纹连接并且有不同尺寸压板组合以适应不同尺寸的木材压缩。 Wherein, the top pressure cylinder 1 is connected with the top pressure plate 10, and the side pressure cylinder group 3 is connected with the side pressure plate 9, wherein the connection mode is threaded connection and there are different sizes of pressure plate combinations to adapt to the compression of wood of different sizes.
其中，顶压油缸1与侧压油缸组3是相对固定的，而顶压板10与侧压板9之间是可以相对滑动的。 Wherein, the top pressure cylinder 1 and the side pressure cylinder group 3 are relatively fixed, while the top pressure plate 10 and the side pressure plate 9 can slide relatively.
如图2所示，本发明使用过程中，将天然实木木材平放入由工作台11，顶压板10，侧压板9形成的压缩腔中，下行程开关4与木材上表面相平，顶压油缸1控制顶压板10、侧压板9与侧压油缸组3下降，当压力达到预定值时，溢流阀溢流，保持压力，随后侧压油缸组3加压，侧压板9将木材固定，接着主顶油缸7开始对木材进行加压压缩，当主顶油缸压力7达到规定值时，保持一定时间后主顶油缸7泄压，随即顶压油缸1与侧压油缸组3泄压，顶压油缸1将顶压板10与侧压油缸组3提起，取出压缩好的木材，进行下一步冷弯曲或热弯曲处理。 As shown in Figure 2, during the use of the present invention, the natural solid wood is put into the compression cavity formed by the workbench 11, the top pressure plate 10, and the side pressure plate 9, and the lower travel switch 4 is flat with the upper surface of the wood, and the top pressure Cylinder 1 controls the top pressure plate 10, side pressure plate 9 and side pressure cylinder group 3 to descend. When the pressure reaches a predetermined value, the overflow valve overflows to maintain the pressure. Then the side pressure cylinder group 3 is pressurized, and the side pressure plate 9 fixes the wood. Then the main top cylinder 7 starts to pressurize and compress the wood.

在油路设计上，如图2所示，三组液压缸采用两个液压泵的形式，其中液压泵I 5单独为侧压油缸组3提供动力，液压泵II 6为顶压油缸与主顶油缸提供动力。 In terms of oil circuit design, as shown in Figure 2, the three groups of hydraulic cylinders adopt the form of two hydraulic pumps, of which hydraulic pump I 5 provides power for the side pressure cylinder group 3 alone, and hydraulic pump II 6 is the top pressure cylinder and the main top pressure cylinder. Cylinders provide power.
各油缸均达到一定的压力后失效。失效装置是液压装置。这是实现失效装置的相当简单的方式，这是因为在液压系统中，可以使用液压装置，而不需要显著地增加结构或保养成本。 Each oil cylinder fails after reaching a certain pressure. The failure device is a hydraulic device. This is a rather simple way of implementing a deactivation device, since in a hydraulic system hydraulic means can be used without significantly increasing construction or maintenance costs.
