Metal cold rolling mill is composed of working mechanism and transmission mechanism. in:
① The working mechanism consists of frame, roll, roll bearing, roll adjustment mechanism, guide device, rolling seat and other parts.
② The transmission mechanism is composed of a gear frame, a reducer, a roll, a coupling shaft, a coupling and other parts.
Working principle:
The metal cold rolling mill uses an electric motor to drag the steel bar, and the load-bearing roll and the work roll of the metal cold rolling mill jointly apply force to the two sides of the steel bar. The purpose of rolling out cold-rolled ribbed steel bars with different diameters is achieved by changing the size of the gap between the two rolls.
① Bearing roller: The bearing roller of the metal cold rolling mill is the one that is close to the stand. When producing ribbed steel bars, this roller plays the role of holding up the steel bars, and evenly distributes the weight of the steel bars and the work rolls. disperse on the load-bearing roller, so that the lower surface of the steel bar is ribbed.
② Work roll: The work roll of the metal cold rolling mill is on the top of the load-bearing roll, which is far from the stand, so the roll is mainly used to roll the steel bar supported by the load-bearing roll when producing ribbed steel bars. effect, so that the upper surface of the steel bar is ribbed.
Maintenance:
① Check whether the electrical system of the metal cold rolling mill is normal before starting each shift;
② And check whether the oil level of each fuel tank is normal;
③ Whether the oil filling parts are filled with oil;
④ Whether the parent material feed is reasonable;
⑤ After checking the above matters;
⑥ The electrical parts of the metal cold rolling mill should always be cleaned of dust and debris.
