When the actual current value is lower than the set value, adjust the control current of the servo pressure reducing valve in time to increase the pressure of the oil cylinder, thereby increasing the power of the grinding wheel to the billet until the set current. value is reached.

Technical features and benefits

• constant power, variable even grinding action
• Even grinding control at the end of the blank
• Hengshan independently developed the high efficiency gear grinding head
• CCD surface detection system
• hot grinding technology
• High automatic grinding and automatic rounding function can be realized with one button

Constant power, floating even grinding
When the actual current value is lower than the set value, adjust the control current of the servo pressure reducing valve in time to increase the pressure of the oil cylinder, thereby increasing the power of the grinding wheel to the billet until the set current. value is reached.
When the actual current is greater than the set value, adjust the control current of the servo pressure reducing valve in time, reduce the pressure of the oil cylinder, reduce the power of the grinding wheel to the billet, and restore the current to the set value. , to achieve continuous grinding power.
Currently most grinders ensure that the billet curvature is + - 5mm/M and the total length is no more than 50mm
Hengshan electromechanical can meet + - 25mm/m with total length 110mm
Advantages of gear grinding head
Optimize motor transmission power: The transmission power of the original belt grinding head is 75% of the motor power, and the transmission power of the gear grinding head is 98% of the motor power. It can save 20% in power consumption.
Improvement of production capacity and grinding efficiency: The grinding efficiency of the gear grinding head can be increased by 15% compared to the original belt grinding head
Optimization of grinding wheel consumption: Gear grinding head can save 10% in grinding wheel consumption compared to the original belt grinding head (test carried out in Nangang)
Optimize the working speed of the grinding machine: gear grinding head can greatly save maintenance time and replace belts, pulleys and other maintenance time.
Working time of gear grinding head: more than 6000 hours, and the longest working gear grinding head is 14000 hours
Lubrication method: Oil-gas lubrication system of German rebs company is adopted. No need to repair or replace the sealing ring
