(1) The work table of the Butt Welding Machines for receiving and feeding materials should be kept level with the lower part of the cutter. The length of the work table can be determined according to the length of the processed material. When processing long steel bars, special personnel should be provided to assist and follow the operator’s instructions. Do not push or pull at will.
(2) Before starting the Butt Welding Machines, it must be checked that the cutter has no cracks, the knife holder bolts are tight, and the protective cover is secure. Then turn the pulley by hand, check the gear meshing clearance, and adjust the cutter clearance.
(3) After starting the Butt Welding Machine, it should be run dry first, and check that all transmission parts and bearings are operating normally before operation.
(4) Material shall not be cut when the machine does not reach normal speed. When cutting, you must use the middle and lower parts of the cutter, hold the steel bar tightly align it with the knife edge, and quickly feed it. The operator should stand on the side of the fixed blade and press the steel bar hard to prevent the end of the steel bar from popping out and injuring people. It is strictly forbidden to hold the steel bar with both hands on both sides of the blade and lean over to feed.
(5) Do not cut steel bars whose diameter and strength exceed those specified on the machine nameplate and red-hot steel bars. When cutting multiple steel bars at one time, their total cross-sectional area should be within the specified range.
(6) When cutting low-alloy steel, the high-hardness cutter should be replaced, and the cutting diameter should comply with the requirements on the machine nameplate.
(7) When cutting short materials, the distance between the hand close to the blade and the blade should be kept more than 150mm. If the hand grip is less than 400mm, the short end of the steel bar should be pressed or clamped with a casing or clamp.
(8) During operation, it is strictly forbidden to use hands to directly remove broken ends and debris nearby. Non-operators are not allowed to stay around the steel bar swing and near the knife edge.
(9) When it is found that the machine is not operating normally, making abnormal noises or the cutter is skewed, it should be stopped immediately for maintenance. Maintenance and maintenance must be done after shutting down the machine and cutting off the power supply.
(10) Before operating the hydraulically driven cutting machine, check and confirm that the hydraulic oil level and motor rotation direction meet the requirements. After starting, it should be operated without load, the oil release valve should be loosened, and the air in the hydraulic cylinder should be exhausted before cutting ribs.
(11) Before using the manual hydraulic cutting machine, the oil drain valve should be tightened clockwise. After cutting, it should be loosened counterclockwise immediately. During operation, the cutting machine should be held firmly with hands and insulated gloves should be worn.
(12) After the operation of the Butt Welding Machines, the power supply should be cut off, and debris between the cutters should be removed with a steel brush to clean and lubricate the entire machine.
