Operation theory of cold rolling mill with more than 2 rollers
As shown: Drive by the main motor, Via the reducer, Brace connecting Rod structure to drive rocker system (OABCD) to do swing movement, thus, the upper and lower connecting rods drive the nose sleeve and the roller Frame to make regular reciprocating straight movement along the rolling line. The difference between their reciprocating straight travel is the rolling travel, a period of reciprocating movement, roller No 3 rolls on slide NO 4 and the pass formed by the three roller is regulated by the slide curve to complete a change of “Big-small-big”. When the taper Die is maximum, the roller does not contact with the Shell 2. At this time, the shell rotates at a specified angle and pushes forward a specified Length by the feeding Structure. After that, the pass gradually becomes smaller, to the taper DIE is the smallest, complete the finished Size of wall thickness, Inner and Outer diameter. The continuous completion of such a cycle, to achieve the tube shell Rolling.
