1. Protection of hydraulic system
Regarding the protection of the hydraulic system, when the machine tool is used for a period of time, the performance indicators such as the viscosity of the hydraulic oil will be affected, and the cleanliness of the oil will also decrease. Some more precise hydraulic valves will have a negative effect of significant wear, so it should be It is stipulated that the hydraulic oil should be precipitated and filtered once a month, and replaced every three months, which can improve the service life of the hydraulic components. Together, check the solenoid valves, pressure valves, throttle valves, overflow valves and pressure relays. , Especially when the pressure gauge jitter exceeds ±0.5×105Pa, it must be stopped, and the valve core must be cleaned with clean gasoline to make it work normally.
2. Protection of the electrical system
The electrical system mainly consists of some control components, such as relay output, input interface, electrical box module, and cable line protection against oil immersion. These elements should be checked regularly, and the cables should be routed as high as possible to avoid landing. The signal is aborted.
3. Protection of mechanical organization
The mechanical organization is mainly whether the bearing load accuracy of the bearing meets the requirements, whether the smoothness of each smooth part is in place, try to prevent the gears at the high-speed running gears, and the guide rails are not smooth and the guide rails are damaged.
How to choose and adjust the angle of the grinding wheel of the alloy saw blade grinding machine
The
saw blade grinding machine uses the grinding wheel as an abrasive tool to process cylindrical gears or gear processing machines for processing tooth surfaces of certain gears. It is mainly used to remove the deformation after heat treatment and improve the precision of gears. The precision of the teeth after grinding can reach 6 to 3 (JB179-83) or higher. The choice of grinding wheel depends on the material and heat treatment of the workpiece. Generally, heat-treated parts require softer grinding wheels for higher hardness, and harder grinding wheels for those without heat treatment. The particle size of the grinding wheel depends on the requirements of the grinding surface finish. As for the material of the grinding wheel, brown corundum is mostly used for parts before heating, and white corundum or ceramic corundum is used after heating.
First, adjust the grinding wheel to the lower level, install the saw blade on the saw blade seat, set the pressure plate, turn the hand wheel, the screw drive the saw blade to move up and down, adjust the saw blade to 30 ~ 50 mm over the indenter, and press Head tightly. Adjust the fixed position of the saw tooth at the end of the gear shifting action, and align the grinding wheel with the saw tooth of the saw blade. Then adjust the grinding wheel to a better position to start grinding. Angle adjustment of the grinding wheel of band saw blade gear grinding machine: to adapt to grinding saw blades with different serrated rake angles. The angle of the mounting plate of the grinding wheel can be adjusted. The method is to loosen the two bolts of the mounting plate of the grinding wheel holder (the nut should not be removed) and then rotate the wheel holder in a clockwise direction. Turn to the front end of the grinding wheel. When the saw blade is fed and ground, it can touch the entire plane of the front angle of the saw tooth (from the tooth tip to the tooth root).
