So as to ensure that the steel rope can stably and efficiently transmit power.
Description of the use of the utility model
1. Summary of the invention
The use instruction aims at guiding operators to correctly use the square billet feeding automatic steel tilting device, and ensures that the device can exert the maximum effect in the production process. By following the description, operators can effectively solve the problem of bending of square billets in the furnace feeding process, and the production efficiency and the product quality are improved.
2. Device inspection and preparation
Before starting the operation, please ensure that all parts of the automatic billet feeding and tilting device are intact without obvious mechanical faults.
Checking whether the cylinder and the control system thereof work normally or not, and ensuring the stable air source supply.
And the key components such as the lifting steel rope, the fixed pulley and the power unit are not worn or damaged.
The portal frames on the two sides of the roller way are firmly installed, and the position adjustment is correct.
3. Operating procedure
When the monitoring system detects that the transverse bending square billet in the roller bed affects the charging, an operator should press the control button of the air cylinder immediately.
After the cylinder is started, the traction force is provided to lift the lifting steel rope, so that the square billet bearing frame and the square billets in the square billet bearing frame are lifted to a limited height.
As the square billet is pulled to a defined height, the transversely curved square billet is turned over under the influence of gravity. At this time, the square billet bearing frame rotates in a barrier-free way by taking the bearing as the circle center, and the square billet bending direction is helped to be automatically turned to be longitudinal.
After the square billet is turned to a longitudinal state, the control button of the air cylinder is pressed down again, so that the air cylinder is restored to the original position.
The lifting steel rope is downwards placed, the lifting steel rope and the square billet are returned to the guide groove, and the square billet is ensured to be smoothly fed into the furnace for heating and rolling.
4. Notice matters
