Pneumatic tool safety operation procedures
1.Before starting, first check that the tool and its protective device are in good condition, clamp normally, no looseness, good air seal, no aging, corrosion of the air pipe, safety device at the pressure source is intact, duct connection is firm, tool part is not Cracks, burrs.
2, when starting, the first trial run. After the start should be stable without severe vibration, dynamic inspection is correct, and then work.
3, pneumatic grinding wheel use requirements:
(1) Dust masks must be worn;
(2) When grinding the workpiece, the grinding wheel must not be allowed to stand on both sides in order to prevent the fire sand from splashing into the person.
(3) When grinding workpieces with a grinding wheel, first start to idle and normal, and then light and heavy to get secure, uniform force. But the pressure can not be too large or violently bumped, so as not to break the wheel hurt.
(4) After the work is completed, close the valves and place the grinder in a dry and safe place. The wheel should be protected from moisture and be broken and hurt when used.
(5) It is forbidden to start the grinding wheel or use it to strike the grinding wheel. When changing the grinding wheel, it is necessary to check the grinding wheel for cracks. It should be firmly clamped and not allowed to use the unqualified grinding wheel. When cleaning, it is necessary to stop using a brush to clean.
4, pneumatic tools should maintain the automatic shut-off valve intact, to ensure that in operation, only start the operation by force to work.
5, Pneumatic tools should be specially responsible for inspection, custody, and regular maintenance.
(4) Safety Operation Procedure for Common Grinder
1. The public grindstone machine should be in charge of it and inspect it regularly to ensure normal operation.
2. The operator must wear protective glasses and start the dust removal device to work.
3, people who are not familiar with the performance of the grinder can not use the grinder.
4. Before starting the grinder, it is necessary to carefully inspect whether there is any debris between the grinder and the shield. When it is confirmed that there is no problem, start the grinder again.
5. When the grinder is seriously damaged due to long-term use, the radial runout and vibration are too large to be used.
6, grinding wheel failure due to poor maintenance, or shaking the shaft axis, there is no support tool holder, the installation does not meet the safety requirements, are not allowed to start.
7. The new grinding wheel should comply with the general safety operation rules of the grinding mill. It must be seriously selected. For grinding wheels with cracks and damage, or grinding wheels with poor grinding wheel shaft and grinding wheel holes, no use is allowed. Wheel diameter Should be larger than 1/30 of the nominal diameter of the grinding wheel, and a soft gasket should be installed between the grinding wheel and the chuck. When changing the screw on the grinding wheel, the force should be evenly distributed. Do not go too loose or too tight. When installing the grinding wheel, add padding. Balanced, trimmed, balanced, and calibrated before use.
8, the protective cover of the grinder and the transparent protective plate and the vacuum cleaner must be checked and completed.
9. The distance between the tool holder and the grinding wheel working surface can not exceed 3mm. Before grinding, it should be adjusted to meet the total requirements and the device is firm.
10, After the grinder starts, it should idle for 2-3 minutes. It can be used only when the grinding wheel turns to normal. When grinding, it should be operated sideways. It is forbidden to grind the surface of the grinding wheel.
11, when grinding the workpiece or tool, you can not use too much force, not allowed to hit the grinding wheel.
12. On the same wheel, it is forbidden for two people to use at the same time, and it is forbidden to wear on the side of the grinding wheel. When grinding the workpiece, the operator should stand on the side of the grinder. Do not stand on the front of the grinder to prevent the wheel from cracking. ,have an accident.
13, special grinding wheel for grinding tools is not allowed to grind any other workpieces and materials.
14. For small, large and unsuitable workpieces, do not grind on the grinder. In particular, small pieces should be held firmly in the fixture to prevent them from being squeezed into the grinder or between the grinding wheel and the pallet. Grinding wheel crushed.
15, the grinding wheel is not allowed to touch water, it should always be kept dry to prevent the loss of balance after wet water, found that the grinding wheel surface groove, when the radial run-out is too large, should be polished.
17. Shut down the turbine before shutting down the grinder, and finally stop the dust removal device.
