木工机械设备危险因素分析

       木工机械设备一般属于危险性较大的机械设备，它的刀刃比一般金属切削机床的更加锋利。很可能在使用过程中伤害操作人员的手掌、手指等部位，而且很容易致残。所以对木工机械设备的管理应更加严格，确保不发生事故。

1.设备使用加工过程中的危险因素

（1）由于木工机床上的刀具一般处于高速的旋转，机床上的零件有可能因意外情况破裂而碰撞刀具，高速飞出的小物体一样易对操作人员造成伤害；

（2）木工机械大多采用手工送料，送料过程中难免会出现受阻，手会不自觉的伸进去检查，十分容易与刀具接触造成伤害；

（3）操作者不熟悉木工机械设备的性能，不按操作规程作业，或者操作时没有相应的防护措施，都容易造成伤害事故；

（4）机械设备使用过程中，刀具转速高，惯性很大，不小心接触后也难以短时间制动，这会使操作者受到更严重的伤害；

（5）对木材进行加工过程中，木屑的产生无法避免，需要控制其飞出方向，防止击打操作者造成伤害；

（6）木材是易燃物品，木屑更容易着火，如果木屑与空气充分接触很容易引起爆炸，机械设备要选用无火花的供电方式，并在厂区内严格禁止明火出现；

（7）木工机械设备操作台一般采用金属材料，带动刀具旋转的电机基本上是由三相380v电源供电，一旦设备绝缘出现问题，操作台带电伤害操作人员。

Woodworking machinery equipment generally belongs to the more dangerous mechanical equipment, its blade is sharper than the general metal cutting machine tool. It is likely to hurt the operator's palms, fingers and other parts during use, and it is easy to be disabled. Therefore, the management of woodworking machinery and equipment should be more strict to ensure that no accidents occur.

1. Risk factors in the process of equipment use

(1) Because the tool on the woodworking machine tool is generally in a high-speed rotation, the parts on the machine tool may crash due to accidental rupture, and the small objects flying out of the high speed are as easy to cause injury to the operator;

(2) Woodworking machinery mostly uses manual feeding, feeding process will inevitably be blocked, the hand will not consciously reach into the inspection, it is very easy to contact with the tool to cause damage;

(3) The operator is not familiar with the performance of woodworking machinery and equipment, does not operate according to the operating procedures, or does not have corresponding protective measures during operation, which is easy to cause injury accidents;

(4) During the use of mechanical equipment, the tool speed is high, the inertia is large, and it is difficult to brake for a short time after accidentally contacting, which will cause more serious injury to the operator;

(5) In the process of wood processing, the generation of wood chips is unavoidable, and it is necessary to control the direction of its flight to prevent injury to the operator;

(6) Wood is flammable items, wood chips are more likely to catch fire, if the wood chips are in full contact with the air it is easy to cause explosion, mechanical equipment to choose non-spark power supply, and strictly prohibit open flame in the plant;

(7) Woodworking machinery equipment operating platform is generally made of metal materials, the motor that drives the tool to rotate is basically powered by three-phase 380v power supply, once the equipment insulation problems, the operating platform live damage to the operator.
