2. When loading and unloading the workpiece, the rocker arm should turn sideways, and the safety spreader should be selected according to the weight and shape of the workpiece. Do not bump the equipment when lifting and lowering it lightly.
3. When installing the reducer sleeve and drill handle, the taper must meet the standard, and the conical surface must be clean and free of scars.
4, the height of the rocker arm in the work should be properly adjusted, should not be too high.
Before drilling, the rocker arm column and spindle box must be locked.
5. Workpieces and tools must be clamped firmly and reliably, small pieces must be drilled with fixtures, and workpiece drilling must be rigorous.
6, thin plate, large or long workpiece vertical drilling, must be pressed firmly, it is forbidden to process by hand.
7. When drilling through holes, the bottom surface must be padded with pads, and the equipment workbench shall not be injured by drilling. When drilling a through hole, the workpiece should be decompressed slowly to prevent the platform from being damaged.
8, drilling operations must be slow feed, to prevent drilling bit and machine tool damage caused by sticking, resulting in drilling is not vertical and concentric.
9. Drill through holes with automatic feed. When drilling through, the automatic feed should be changed to manual feed.
10. When adjusting the drilling depth for automatic feed, the drill bit should be contacted with the workpiece first, and then the feed lug should be adjusted to the required depth value and locked.
1 1. When unloading the drilling fixture (cutter), the spindle should retreat to the end face of the headstock, and then gently tap it with a standard oblique iron and hammer. Do not touch the drill pipe.
12, always pay attention to remove iron filings when drilling. When there are long chips on the drill bit, we should stop to remove them. Don't pull them with your hands in the wind. We should clean them with a brush or iron hook. Don't use off-center drilling tools when reaming.
13, pay attention to the overload phenomenon in the work, stop the automatic feeding immediately if there is abnormal noise, and eliminate the overload reason.
14. When tapping, control the spindle to rotate forward and backward, but pay attention to put the handle in the fixed groove.
15, it is forbidden to shift gears when driving. If the handle of the change gear is not in place, it should be moved slowly before changing, but it is not allowed to pull the handle hard.
16. When drilling, the drill bit shall not stop before leaving the workpiece.
It is forbidden to stop the rotating drill by hand. When reversing, you must wait for the spindle to stop before starting.
17, it is forbidden to weld or straighten the workpiece on the equipment.
18. Pay attention to the sharpness of the drill bit and cutter when processing, and the drill bit and cutter that are not sharp can no longer be used.
19. When drilling, use machine tool coolant for cooling, and don't use clean water for cooling.
20, when the equipment abnormal phenomenon, such as oil impassability, abnormal sound, local temperature rise, etc. Do not use it forcibly, and notify the maintenance personnel immediately if it cannot be ruled out.
2 1 When the machine tool fails or is in a dangerous situation, press the emergency stop button first, and then cut off the main power switch; Power transmission operation is prohibited before troubleshooting.
22, open the door of the machine tool electrical appliances, must cut off the main power switch.
23, when the equipment accident, should keep the scene and immediately report to the department head.
24. When the equipment is started, it is forbidden for operators to leave their posts or entrust escrow.
25. After the work, the drill bit must be removed and the handles placed in the non-working position. The front of the car should stop near the column, lower the rocker arm properly and brake, and then cut off the power supply to prevent accidents.
Extended data daily maintenance
65438+ Clean the surface of the guide rail and remove burrs on the workbench. Check the screw, handball and hand board, and check the flexibility and reliability of each handle.
2. Maintenance of spindle feed box of radial drilling machine: check the oil quality, keep it in good condition and the oil quantity meets the requirements. Remove burr from spindle taper hole. Clean the hydraulic transmission system and oil filter, and adjust the oil pressure.
3. Inspection of the rocker arm and lifting clamping mechanism of the radial drilling machine: Check and adjust the lifting mechanism and clamping mechanism to make them sensitive and reliable.
4. Inspection of the lubrication system of the radial drilling machine: To clean the linoleum, it is required that the oil cup is complete, the oil circuit is smooth and the oil window is bright.
5. Inspection of cooling system of radial drilling machine: clean cooling pump, filter and coolant tank. Check the coolant pipe to make sure there is no water leakage.
6. Inspection of the electrical system of the radial drilling machine: clean the dust inside and outside the motor and electrical box. Turn off the power supply, open the electrical door cover, and check whether the electrical connectors and electrical components are loose and aging. Check whether the limit switch works normally. Whether opening the door and cutting off power will work. Check whether the hydraulic system is normal and whether there is oil leakage. Whether the control switches of all electrical appliances are normal.
7, check the oil quality, keep good, oil quantity meets the requirements.
8, remove the spindle taper hole burr.
9. Clean the hydraulic transmission system and oil filter and adjust the oil pressure.
10, remove impurities on the spindle, oil the spindle, and ensure the spindle lubrication.
Institutional inspection
Check and adjust the lifting mechanism and clamping mechanism to make them sensitive and reliable.
Lubrication system inspection
Cleaning linoleum requires complete oil cups, smooth oil passages and bright oil windows.
Electrical inspection
1, clean the dust inside and outside the motor and electric box.
2. Turn off the power supply, open the door cover of electrical appliances, and check whether the electrical connectors and electrical components are loose and aging.
3. Check whether the limit switch works normally. (Power-on inspection is required, so pay attention to safety)
4. Whether opening the door and cutting off power will play a role.
5. Check whether the hydraulic system is normal and whether there is oil leakage.
6. The electrical control switch is normal.
