Description

The equipment of rolling metal rod wire

Technical field

The invention belongs to the metal rod wire rolling technical field, be specifically related to equipment used in a kind of tandem rolling production line for rolling metallic rod wire.

Background technology

At present, rolling metal rod wire has dual mode, and a kind of is that three roller cross-arranging types are rolling, and as shown in Figure 1, employed equipment is common three-high mill.The rolling mode rolled piece earlier by in first three-high mill, roll between the lower roll in the past, come by last, middle rolling again, change over to then second three-high mill coexist the same back and forth rolling on first three-high mill, up to rolling out finished product.This rolling mode is to drive one group of milling train by cover power and transmission device to be rolled, and shortcoming is: (1) mill speed is low, and temperature drop is big, can not realize automated production.(2) dimensional accuracy of rolled products, performance are difficult to reach the high-quality requirement.Another kind is many duo mills that in-line is arranged, as shown in Figure 2, that roll adopts is flat, grade separation carries out continuous rolling for arranging, its weak point is that transmission device is many, production line length, equipment and capital expenditure are big.

Summary of the invention

The purpose of this invention is to provide a kind of new metal rod wire continuous rolling production line device therefor, can satisfy the production requirement of low, the many kind of cost, high accuracy, high-test metal rod wire rod effectively.

The present invention is achieved in that

Roughing unit, middle milling train group and mm finishing mill unit are respectively that the motor reduction box by separately and gear-box drives some duo mills and three-roller Y shaped milling train is formed respectively is installed on a support; Guide and guards is equipped with in porch and exit at every rolling mill roll pass; The frame of described duo mill involutes left frame and right frame, and the shape of this frame is to be seen as rectangle along rolling direction, on the side of frame with on the corresponding position of roll bearing the housing screw that is used to adjust the roll shop building distance is being installed; Described transmission distribution mechanism is installed in roll both sides in the frame; Described pass schedule is the mixing pass schedule that duo mill pass and three-roller Y shaped design of section of rolling mill are formed, and the pass of described duo mill is a circular hole, and the pass of three-roller Y shaped milling train is positive and negative triangle pass.

Advantage of the present invention and good effect are:

(1) adopted on the support by motor respectively the reduction box by separately and gear-box drives some duo mills and three-roller Y shaped milling train is rolled, cancelled two roller vertical mills, the set structure compactness saved floor space and equipment investment.

(2) the mixing pass schedule that adopts duo mill pass and three-roller Y shaped design of section of rolling mill to form.The rolling rolled piece that makes of two roll pass obtains bigger distortion, and the rolling rolled piece stress that makes of three roll pass is good, and the precision height has reduced the workload that pass is adjusted.

(3) duo mill adopts the opposite opened frame of rectangle, and equipment volume is little, and the mill stiffness height reduces the spring amount of roll gap, thereby has guaranteed the precision of rolled piece, also is convenient to processing, dismounting and the replacing of frame.
