Abstract
The invention discloses a kind of online stress eliminating devices of steel bar cold rolling, it includes rack, vertical idler wheel, transverse-roller, rolling wheel support, idler wheel is mounted on machine frame inside by rolling wheel support, every group of transverse-roller and the angled cross arrangement of vertical idler wheel, rack-mounted rolling wheel support can be adjusted relative to rack along holder axis.In use, the device is installed in rolling mill production line, first adjusts idler wheel rotation angle and adapt it to the stress after reinforcing bar direction changes, then make roller compression reinforcing bar by inwardly adjusting rolling wheel support and reaches required deflection.Adjustment finishes in cold rolling process, and reinforcing bar, which is acted on by transverse-roller with vertical idler wheel, generates being bent for different direction, and internal stress can adequately be discharged, and making cold rolled reinforcing bar, there are one better extension effects.
Description
Technical field
The invention belongs to the stress eliminations in a kind of auxiliary device of steel bar meter more particularly to steel bar cold rolling production process
Device.
Background technology
By cold rolling, its intensity improves general wire rod plain bar, and same diameter can bear the rupture pull force of bigger,
But what is brought therefrom is the decline of elongation percentage, this is also the disadvantage of cold rolled reinforcing bar.In order to make the extension of the reinforcing bar by rolling
Restored, stress eliminating device generally is set at milling train rear portion, elongation is improved by eliminating stress, currently, stress elimination
Device is generally alternating bending by the way of, and the form of realization is that the staggered garden roller of a row is in one plane arranged,
When reinforcing bar is by garden roller, since being staggered for garden roller changes the running orbit realization alternating bending of reinforcing bar, but such mode
Leading to the deformation of reinforcing bar, the effect of stress elimination is not thorough only in one direction.
Invention content
Problem to be solved by this invention is to provide a kind of online stress eliminating device of steel bar cold rolling, it is in the operation of rolling
In, to needing the reinforcing bar of stress elimination to realize the bending of multidirectional through rolling, the stress inside reinforcing bar is discharged to greatest extent, with
Improve the elongation of reinforcing bar.
A kind of online stress eliminating device of steel bar cold rolling of the present invention, it includes rack, vertical idler wheel, transverse-roller, idler wheel
Holder and guide sleeve, transverse-roller and equal two one group of vertical idler wheel are mounted on machine frame inside, roller axis by rolling wheel support
It is vertical with holder axis, every group of transverse-roller and the angled cross arrangement of vertical idler wheel, rack-mounted idler wheel branch
Frame can be adjusted relative to rack along holder axis.
Transverse-roller can rotate with vertical idler wheel relative to the axis of rolling wheel support.
The surface of transverse-roller and vertical idler wheel can be the curved surface of indent.
Guide sleeve is installed, guide sleeve uses wear-resistant material at the both ends wire inlet-outlet of rack.
The cross section of rack can be used it is rectangular circle can also be used, when using rectangular, transverse-roller and vertical idler wheel hang down
Directly, when using round, the relative position of transverse-roller and vertical idler wheel can according to circumstances adjust.
In use, replacing former stress eliminating device to be fixedly installed in rolling mill production line the stress eliminating device, at this time
Transverse-roller is adjusted by rolling wheel support to rack outer wall with vertical idler wheel, and front end of the reinforcing bar after cold rolling through device is facilitated to lead
It is penetrated to set, first adjusts idler wheel rotation angle and adapt it to stress after reinforcing bar direction changes, then by inwardly adjusting idler wheel branch
Frame makes roller compression reinforcing bar and reaches required deflection.Adjustment finish in cold rolling process, reinforcing bar by transverse-roller with
The effect of vertical idler wheel generates the bending of different direction, and amount of bow can be adjusted according to circumstances at any time, and internal stress can obtain
To sufficient release, making cold rolled reinforcing bar, there are one better extension effects.
