(1) Before working, it is necessary to check in detail whether the tools used are in good condition. The tools used for punching, cracking, nicks, and loosening should be repaired or replaced. Sledgehammers, such as hand hammers, must be equipped with barbed iron wedges with wooden handles. The hammer top must be smooth and clean. Sledgehammer wooden handle should be soaked in water before use.

(4) The quenching of the scorpion should be appropriate, and it is found that the spurs must be polished at any time, and the quenched tools must be quenched at the top. High-carbon steels are not allowed to make impacted tools.
(5) When the two men hit the sledgehammer, they were not allowed to confront each other, and they must pay attention to the ups and downs of the hammer, look forward to the future, prevent injury, and pay attention to the point of falling, so as to prevent any deviation. It is strictly forbidden to wear gloves. No one is allowed to stand near the front and rear.
(6) The palm fitter does not push the forceps straight into the body, and the fingers are forbidden to extend into the two pliers handles, and the feet cannot be near the anvil.
(7) When forging the workpiece, the workpiece should be placed in the center of the anvil and should be flat and stable. Before burning a red workpiece, remove the metal surface of the workpiece.
(8) The heating temperature of the workpiece should be appropriate. The workpiece with too high or too low temperature can not be strong. No air hammer is allowed.
(9) When forging the workpiece, the gripper must master the command, but it is forbidden to use the hammer to indicate by hand, and it is not allowed to move the workpiece on the anvil by hand, and the head is not allowed to penetrate into the falling range of the hammer.
(10) Red fire forgings should not be delivered long distances, and there should be adequate safety protection measures under special circumstances. The red hot workpieces that are forged are prohibited from being piled up. They should be separated from other objects, and the stacking location and logo should be designated to prevent accidental burns.
(11) When the cold-headed workpiece is about to be disconnected, do not use force to beat the hammer. The operator will open one side and pay attention to the surrounding pedestrians.
(12) The highly toxic chemicals (such as cyanide, etc.) used for heat treatment must be kept by special persons and set up a hair delivery system. The use of drugs must be familiar with the nature of the drug. Operators have qualified gas masks and are not operated. All personnel are not allowed to approach.
(13) Before leaving work, the fire must be extinguished, the slag should be poured at the designated place, and the rest of the furnace must be shoveled or extinguished with water.
(14) The motors, electrical appliances and hydraulic devices of the forging machinery shall be operated according to the relevant safety requirements.
(15) The machinery installation and layout shall ensure safety, the site shall be leveled, and the workshop shall have heat prevention, cooling and cold protection equipment. Raw materials, semi-finished products, finished products and surplus materials shall not be piled up near the machinery.
(16) Before operation, check that there is no crack damage on the impacted part of the machine; there is no loosening of the main bolts; the mold has no cracks; the operating mechanism, automatic stop device, clutch and brake are all flexible and reliable; the oil circuit is open.
(17) During the operation, it is not allowed to check the workpiece by hand and check the dimensions with the template. When the mold jams the workpiece, it must not be released by hand. Never put hands and tools into the danger zone.
(18) The workpiece must be clamped with pliers and not thrown.
(19) During the operation, the iron oxide skin, scrap material and excess material under shearing can only be removed with a broom or a wooden stick, and should not be removed directly with hands or feet.
2. Air hammer and plywood hammer safety requirements
(1) Before operation, check that there is no looseness in the vibration part, no cracks in the hammerhead, good lubrication, oil supply to the oil pump and the piping system is working properly.
(2) Before the operation, it should be tested for 1-2min. In winter, it should be turned by hand before starting. If the hammer is deactivated for a long time, the water in the cylinder should be drained before starting.
(3) When the temperature in winter workshop is low, hammerhead, pliers and forging mill should be preheated to above 60°C.
(4) The fingers of the pliers personnel must not be placed between the pliers handles, and the workpiece should be firmly clamped. The pliers handle must not face the chest and abdomen.
(5) Before forging, the surface of the workpiece and the iron oxide scale on the anvil should be removed first.
(6) The hammer personnel must obey the command of the pliers personnel during work and must not open or stop the machine at will.
(7) When the forging does not reach the required temperature, when the position of the forging on the anvil is not desirable, the forging cannot be forged when it is unstable or uneven.
(8) In the operation, hammers and anvils should be inspected frequently. If they are not normal, they should be stopped and checked immediately. Before the inspection, the hammers must be firmly fixed.
(9) The lever for lifting the hammer shall not exceed the prescribed position and should avoid hitting the hammer. Do not cold-forge or hammer the burned workpiece.
(10) When cutting the workpiece, stand on the front of the incision is strictly prohibited.
(11) After the work, the hammer should be lifted and the planks placed on the anvil before the hammer is dropped on the plank.
3. Tablet safety requirements
(1) Before starting, check the lubrication and tightening conditions of each part. Adjust the roll according to the thickness of the steel plate.
(2) When leveling the steel plate, the operator should stand on both sides of the machine tool. It is forbidden to stand before or after the machine, or above the steel plate. The surface should be kept clean and there must be no weld metal.
(3) When flattening small pieces or strips of workpieces, a steel plate conforming to the specifications of the equipment shall be placed in front of the two rollers as a backing plate. The small pieces or long pieces to be leveled shall be placed on the backing plate for leveling, and attention shall be paid. One end of the pad should not be less than 300mm from the roll and must not be inclined.
(4) The workpieces to be leveled on the backing plate shall be staggered with each other, and shall not be placed in a straight line. The distance between the two work pieces shall not be less than 100 mm.
(5) When leveling the workpiece, a small amount of the roll should be lowered. Each time the amount of drop is limited to 1 ~ 2mm, and pay attention to the pointer position.
(6) After the work, the rollers should be relaxed to remove the workpiece and the backing plate.
