Structure and composition for rectangle wire rolling mill machine
cold precision rolling mill
cold wire rolling mill
The wire cold rolling mill consists of a working mechanism and a transmission mechanism, among which:
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.
Rolling group introduction:
The gantry horizontal double-active rolling mill consists of two active rolling mills. The installation method and structure of the two rolling mills are the same. The main transmission part adopts the structural form of “motor → reducer → universal shaft →half round wire rolling mill”. Both wire rolling mills are horizontal strip rolling mills, the rolls are installed horizontally, the rolling mill adopts a gantry arch, the roll ring is sleeved on the roll spindle, the nut is fixed, the two ends of the roll spindle are equipped with bearing seats, which are installed in the middle of the gantry, and the bearing seat and the gantry arch The frame is installed together, and the rolls are fixed horizontally in the middle of the gantry, and the upper and lower rolls are installed in the same way. The first-stage reducing mill is to flatten the raw materials, extrude the two-sided ribbed steel bar with crescents through the second-stage forming mill, and twist the guide to adjust the rolling piece to realize the elliptical rolling piece after the first-pass rolling. Finished steel bars are produced.
