(1) Danger of transmission device

Mechanical transmission is generally divided into gear drive, chain drive and belt drive. Due to the components do not meet the requirements, such as mechanical design is unreasonable, the transmission part and the protruding part of the rotation exposed, no protection, etc., may be the handle, clothing twisted into the cause of injury. In chain drive and belt drive, the belt pulley is easy to involve the tool or person's limb; When the chain and the belt are broken, it is easy for the joint to grab the body and the belt to fly and hurt people. In the process of transmission friction and high belt speed, it is also easy to make the belt generate static electricity, generate static spark, easy to cause fire and explosion.

(2) Danger of pressure machinery

Pressure machinery is common punch, scissors, bending machine, crusher, roller press, press and die press. All pressure machines have certain pressure parts, and the pressure parts are dangerous. Because this kind of equipment is mostly operated by hand, the operator is prone to fatigue and boredom, and human error occurs, such as inaccurate feeding results in material pressure flying, mold shifting, hand entering the danger zone, etc., and personal injury accidents are very easy to occur.

(3) The danger of machine tools

The machine tool is a high speed rotating cutting machine, which is very dangerous.

1, its rotating parts, such as drill, lathe workpiece chuck, etc., once intertwined with people's clothes, cuffs, long hair, around the neck towel, hand gloves, etc., personal injury and death accidents will occur;

2. If the operator colliders with the machine tool due to improper operation method, excessive force and improper tool specification, it may cause the operator to collide with the machine tool;

3, the operator station position is not appropriate, may be impacted by the mechanical moving parts, for example, standing in the motion range of the surface grinder or shaper moving parts, may be hit by the surface grinder table or shaper sliding pillow.

4, cutting tool injury, such as high speed milling cutter to cut off fingers and even the arm.

5. Splash hot steel chips, knife chips cut and scalded human body, splash abrasive and broken chips hurt human eyes.

6. Poor working environment, such as insufficient lighting, slippery and dirty ground, unreasonable machine tool layout, narrow passageway and unreasonable stacking of parts and semi-finished products, may cause the operator to slip or fall.
