Shearing machine operation specification
Shearing machine firmly fixed on the foundation, foundation bolt locking nut shall not be loose. Head up and down smoothly. Hydraulic shearing machine, the tool post (or block) within the prescribed range without crawling, stagnation, vibration and impact phenomenon obvious. Shearing machine pressure of oblique gear material feet no serious wear and tear, cut plate uniform compression. The working process of the mechanical and hydraulic guillotine shears and action sequence is normal. Shearing machine when parking on a rest stop on the specified location. Work surface level off, clean, no welding scar and oil pollution. Retainer flexible copper ball rolling feeding is convenient. Shearing machine tool slide fit closely with the fixed joint bearing surface. Head installed correctly, fixed screw. Blade gap adjusting device locking and reliable work, adjust the bolt without sliding wire, disorderly buckle and prominent phenomenon in working mesa. Rest balance device with self-locking structure of safety and protective measures. Rest rest balance device can guarantee in any position to maintain balance. Gear device keep-off accurate, flexible and convenient feeding and reliable in use, and have the complete material concession institutions. Asked of rolling, such as lifting action is flexible and reliable. In the process of shearing, mutual interlocking clutch and brake, namely the clutch, the brake should be release, after release of the clutch, the brake is closed, the vibration motor. Shearing machine of pneumatic friction clutch and brake correctly and securely mounted on the shaft and the flywheel, and ensure the sequential, interlocked, sensitive and reliable compressed air leakage phenomenon. Pneumatic complete motorcycle rub clutch and brake parts in good condition, flexible adjustment and effect is good. Pneumatic friction clutch and brake friction disc and the disc without wear and fever. Rigid clutch and band brake should be interlocked. Brake band of actual contact area is not less than 75% on the surface of the friction. Emergency brake, clutch can immediately release, brake band will be rotation braking, braking. With the clutch and brake and its control mechanisms action coordination, accurate and reliable. Hydraulic and lubrication system without clogging, leakage phenomenon. No leakage phenomenon in the gas pipeline system. Guide rail lubricating oil with oil return or collecting device. Hydraulic and pneumatic system, with a sudden loss of hydraulic and pneumatic or for liquid and gas supply interruption protection and display. At work, the tank oil temperature is lower than 50 ℃, continuous 24 h after working at full capacity, should be lower than 60 ℃. Plate shears hydraulic system pressure gauge should be clear, sensitive, accurate and reliable. No seal pressure gauge is prohibited to use. The impact of the gear running smoothly and all rules. The noise of the shearing machine idle running below 90 db. The flywheel firmly fixed on the shaft, smooth rotation. Fly wheel shaft should be equipped with overload clutch or other overload protection device, and a sensitive and reliable. Dew in the gear lathe bed. Belt wheel, flywheel, coupling and other rotating parts may endanger personal safety protective device. Of shear head may fly out of danger areas must be equipped with protective shields. Shear head and dangerous parts of the pressure device must be equipped with protective measures. Protective equipment such as baffle plate shears shade type, hood, net width can reach the width of the barrier and scissors or workbench width, and can prevent it from the danger zone in shear, pressure; Convenient for observation and operation, the operator and not easy to be dismantled. No parts in contact with the motion of machine tool. The opening and closing of a removable protective fence shall be the interlocking head movement. Shearing machine fixed protection fence in the tool post or other moving parts is running, may not open them. Electrical equipment comply with the design requirements, the nameplate is clear, installation is firm. Electrical connection is good, the wire connection with locking measures. Have electrical vibration impact to shock measures. The pneumatic control system shall have the emergency stop button. Start "button" is higher than that of the button head protection ring, in a button box, plus a set of the tin boxes, and locked, others the operation. Shearing machine motor wiring should be set to metal protection tube; Electrical box intact, the door is shut tight, compression screw (or lock) is complete, fastening, clean, dry, do not loose all electrical parts and the terminal; Good machine protection grounding line (zero). More than 2 m from the ground height set the ladder, platform, and the fence is in line with gb GB4053.2-83; GB4053.3-83; GB4053.4-83. Shearing machine ladder must have interlocking control and drive shaft, the ladder can disconnect main drive power supply when maintenance. Shearing machine should have labels and instructions lubrication, manipulation and safety signs or marks. Host to cooperate with all sorts of auxiliary equipment, the site of endanger personal safety, fitted with protective device.
