Roller bases of section mill

Abstract

The invention relates to roller bases of a section mill, which comprise a sliding chute, a slide block, a two-way screw rod, a centering thread sleeve and a roller on each roller base. The roller bases of the section mill are characterized in that the sides of the sliding chutes at the extending-out ends of the two-way screw rods are provided with transverse beams, the outer sides of the transverse beams are connected with a box body, and the centering thread sleeves are sleeved on the sections of the two-way screw rods in the box body; a centering adjustment mechanism of a worm gear and a worm is connected on the outer side faces of the centering thread sleeves by screw threads; a stop sleeve and a width adjustment mechanism of the worm gear and the worm are sequentially arranged on the sections of the two-way screw rods behind the centering adjustment mechanism of the worm gear and the worm; a rolling center digital display is arranged on the worm exposed end of the centering adjustment mechanism of the worm gear and the worm; and a width digital display is arranged on the worm exposed end of the width adjustment mechanism of the worm gear and the worm. The invention has the advantages of reasonable design, compact structure, easy enhancement of the adjustment accuracy, good self-locking capability, convenient installation of the digital display, easy operation, labor saving, very convenient use and the like.

Description

technology field, [0001] The invention belongs to profile rolling mill equipment, in particular to a roll stand of a profile rolling mill. Background technique [0002] At present, on the profile rolling mill for rolling various profiles, several roll stands are distributed and installed on the stand according to the needs, wherein each roll stand includes a chute on the stand, two slides sliding in the chute Two rollers are symmetrically installed on the top surfaces of the two sliders, and the left-handed section of the two-way screw rod is meshed and connected in one slider, and the right-handed section is connected in the other slider, and connected to the beam outside the chute. The centering wire sleeve is threaded, so that the end of the two-way screw rod outside the chute passes through the centering wire sleeve and protrudes out of the centering wire sleeve, and the centering wire sleeve is driven by the centering handle to move axially to realize the alignment of t...

AI Technical Summary

Problems solved by technology

[0003]1. The adjustment accuracy is poor, because when the centering thread sleeve is threaded on the beam, it is usually connected with a thread with a pitch greater than 1mm, such as M30×1 or M30×1.5 , resulting in poor adjustment accuracy;

[0004]2. Poor self-locking ability;

[0005]3. It is not convenient to install digital displays;

[0006]4. It is very laborious to directly drive the two-way screw by hand;

[0007]5. Not easy to maneuver
