Lubricating grease spit out oil volume and pressure detection function test and adjustment. The functions such as the filter of the air system, the adjustment valve of the oil feeder, and the water impurity test check and necessary adjustment. Air pressure switch setting value check and pressure detection function test and adjustment. Check and adjust the setting value and actual measured value of the mode high indicator switch. Check and adjust the sprocket, chain, transmission shaft, worm gear and other parts of the mold height adjustment device for looseness, abnormality and chain tension. The upper cover of the gear transmission box is removed, the internal parts are worn and the key position is loosened, and the oil tank is cleaned, the lubricating oil is replaced and the running status, noise, and vibration are checked. Test and adjust the oil quantity and pressure of the oil injection point of each part of the transmission system. Piston action of the brake mechanism, brake angle, brake clearance and test point inspection and necessary adjustments to the wear of the blade.

The gap measurement and friction surface inspection of the sliding guide rail and the guide path are adjusted and corrected if necessary. Add manual lubricating grease, pipelines, joints and other inspections for flywheel bearings. Test and check the operation status of the balance cylinder and the oil circuit and joints of the oil lubrication system. Test and check the insulation resistance of motor circuit and electrical operation circuit. Test the accuracy of the whole machine (verticality, parallelism, comprehensive gap, etc.), adjust and correct if necessary. The appearance of the punch and the cleanliness of the accessories, the check points and the mechanical feet (foundation) tighten the screws, the locking of the nuts and the level check if necessary. Clean, maintain and inspect the pumps and pipeline valves of the lubrication system. Pneumatic components and pipelines of the air system are cleaned, maintained, and tested for operation.

Use 3000-4000 hours to maintain and test the performance of the photoelectric safety device and adjust the projection angle and area. The appearance of the other parts of the electrical system, contact wear and loose connection and other point inspections, testing and testing and adjustment of the second-degree rotary cam switch box and emergency stop circuit function. The oil circuit of the overload protection device is cleaned, the oil chamber is cleaned, the oil is replaced, and the pressure action and function test are adjusted. Check and adjust the main motor V-belt wear and tension. Disassembly and disassembly of the components of the brake mechanism (not included in the flywheel) for cleaning and maintenance, clearance inspection and adjustment, and assembly and commissioning. The other parts of the balancer are disassembled and disassembled, cleaned and inspected, and reinstalled and debugged.

Use 6000-8000 hours to maintain the disassembly and disassembly of the sawtooth connecting rod, clean and maintain, check the bite and abrasion of the sawtooth and connecting rod threads, and polish, grind the occlusal surface and apply grease. Slider assembly (ball seat, cap, overload hydraulic cylinder, worm gear, worm, etc.) is disassembled and disassembled, cleaned and maintained, clearance adjustment and wear surface, oil seal inspection and re-applied with grease. After disassembling and disassembling the mold pad, clean and inspect the wear surfaces and reapply grease to assemble the test car.
