Short Stress Steel Rolling Mill Rebar Machine Steel Hot Rolling Mill
The so-called short stress line rolling mill refers to a rolling mill with a shortened stress loop. The stress loop referred to here is a closed loop formed by the rolling mill under the action of the rolling force in the unit of each stressed member such as the stand, referred to as the stress line. The elastic deformation of the stressed member is proportional to its length. Therefore, shortening the length of the stress loop can reduce the elastic deformation of the rolling mill and improve the rigidity of the stand.
Short stress line rolling mill parts Transmission: motor, drive shaft, worm gear, hand wheel, transmission gear Depressing device: screw, depressing nut, balance nut, balance spring, spherical pad Axial adjustment device: gear sleeve, gear ring, thrust bearing, end cover, roll, bearing seat, auxiliary parts, etc.
Advantages of short stress rolling mill
The stress loop is short and the rigidity is high to ensure the high precision of the product, and it is easy to achieve negative deviation.
1. There are positive and negative threads at both ends of the column, which can realize counterweight adjustment, and the rolling center line remains unchanged. It can improve the operation rate, save the time for maintenance and replacement of the guide and guard beams, reduce operation accidents, avoid process accidents such as rolling elbows, impact, and roll winding, and improve the guide and guard life.
2. Convenient axial adjustment and small axial clearance.
3. The balance spring is used, the balance force is unchanged, and the spring is compact in the bearing seat.
4. The rolling mill has good pre-adjustment performance, quick roll change and high yield rate.
6. The bearing seat is automatically adjusted, and the four-row cylindrical bearing is balanced in force, which improves the bearing life.
