Cold Rolling Steel Bar Machine

 

A cold rolling steel bar machine can process hot-rolled wire rods and hot-rolled coils with a diameter between 6.5 mm and 12 mm into finished cold-rolled ribbed steel bars with a diameter between 5 mm and 12 mm. The cold-rolled ribbed steel bars produced can be used in prestressed concrete components and cast-in-place concrete structures, replacing cold-drawn low-carbon steel wires and grade I steel bars, respectively, to save steel.

 

I Description

1. This device adopts PLC touch screen numerical control system to make the operation easier.

2. The production line adopts the most advanced international frequency conversion and servo technology or independent frequency conversion control technology, and it effectively protects the power transmission system and equipment from damage. It maximizes the service life of the machine. It can save electricity 30-40%, the maximum line speed can reach 190 meters, increase production efficiency by more than 40%.

3. We adopt self-developed reducer as the national patented product, which is the fastest speed in China, simplifies the structure of the production line, and makes the equipment more reasonable and compact. (The speed reducer between the main reducer and the main rolling mill is omitted and the deceleration is reduced. Due to the long transmission distance of the machine and many problems connecting the flanges, it effectively improves the transmission efficiency by more than 30%, and improves the stability of the equipment by more than 60%. It effectively improves the production efficiency of the equipment.

4. Straightening machine adopts multiple rounds of synchronous control technology. Straightening effect is good. Less damage to steel bars.

5. Cutting off adopts independent research and development of variable frequency or servo flying shear control system, easy to operate. High degree of CNC, low failure rate, cut off error low.

 

II Working Principle

The cold rolling steel bar machine uses a motor to drag the steel bar, and the load-bearing rolls and working rolls jointly apply force to the two surfaces of the steel bar. By changing the size of the gap between the two rolls, cold-rolled ribbed steel bars of different diameters can be rolled. The load-bearing rolls support the steel bar and evenly distribute the gravity of the steel bar and the working rolls, while the working rolls roll the steel bar to form ribs on the surface of the steel bar.
