【正文】 ould check and confirm the cutter without crack, carriage bolts, protective cover firm. And then hand belt pulley, gear meshing clearance check, adjust the cutting clearance. (3) after the start, should first air operation, check the transmission part and the bearing can be normal operation, operation. (4) machinery does not reach the normal speed, not cutting. When cutting materials, should be used in the next part, cutter, hold the reinforced alignment edge quickly put, the operator should stand in a fixed blade side press bar, should prevent the reinforced end pop. Prohibit the use of both hands in blade on both sides hold reinforced leaned feeding. (5) may not be cutting diameter and strength more than machinery nameplate provisions and a redhot steel reinforced. A cut of a plurality of steel, the total crosssectional area should be within the specified scope. (6) cutting low alloy steel, should be replaced with high hardness cutting knife, cutting diameter shall be in accordance with the provisions of machinery nameplate.(7) cut short when feeding, the distance between the hand and the knife should be maintained above 150mm, such as holding end is less than 400mm, should adopt the casing or fixture to be reinforced short head down or clip. (8) operation, prohibit the use of hand direct clear cutting knife near the end and sundries. Steel swing around and cutter may not stay around, non operators. (9) found that when the machine is not operating properly, abnormal noise or the cutter deflection, should immediately stop machine overhaul. (8) operation, prohibit the use of hand direct clear cutting knife near the end and sundries. Steel swing around and cutter may not stay around, non operators. (9) found that when the machine is not operating properly, abnormal noise or the cutter deflection, should immediately stop machine overhaul. (10) after the operation, the power should be cut off, with the steel brush to clean the sundries cutter machine, cleaning and lubricating.(11) hydraulic transmission type cutting machine operation before, should check and confirm the hydraulic oil and the rotation direction of the motor meets the requirements. After starting, noload operation, loosen oil drain valve, hydraulic cylinder air, can be cut tendons. (12) manual hydraulic cutting machine before use, should the oil drain valve in a clockwise direction, after the cutting, should immediately counterclockwise unscrewing. During the operation, the hand should be steady and cutting machine, and wear insulated gloves. This article introduces a kind of architectural lie type steel cutting machines. Its operating principles are: It use electric motors level triangle belt transmission and secondary gear transmission to slowdown. Then, it drives the crank rotate, The crank connected to slide block and moving blades in the slippery way make the back and forth straight line sport, makes the moving blades and the fixed blade shear and cut steel. According to the working environment choice thetype of electric motors,using horizontal installation, protection of the electrical, squirrelcage threephase asynchronous motor. momentum, and the scope of power, transmission efOption three slowdown,first level belt slowdown, followed by the secondary gear deceleration. firstthe introduction of automated, because it has a buffer, absorb shock and operate smoothly, small noise, and can protect the over loading. Then introduce a secondary gear deceleration slowdown, because gear transmission can be used to transmit arbitrary space between the two axis movement andficient transmission accurately, long using life, such as safe and reliable character. Power output by electric motors through slow down transmission system to import power to the executive body. As the system make rotation movement, The steel cutting machine needs the back and forth straight line sport ,in order to achieve this transformation, we can use c slidercrank institutions or gear and rack. I decided to consider realistic using slidercrank as the executing.35
