Description
Technical field:
The utility model relates to the cold-rolling equipment technical field, particularly relates to the centralising device of thin coil sleeve in the production of band steel.
Background technology:
In the prior art, cold rolling mill when the thin material coil of strip of rolling thickness≤0.45mm, for avoiding the thin material inner ring volume that collapses, when take-up will be at steel bushing liner of the inner increase of coil of strip, steel bushing will be sent into earlier and be enclosed within on the coiling machine mandrel.Generally all require the center line of steel bushing length and rolling centerline to be consistent, steel bushing is all sent into the coiling machine mandrel by sleeve transportation lift cart automatically, for this reason, before steel bushing is sent into the coiling machine mandrel, needs on lift cart, to realize earlier centering.Existing steel bushing all is to be delivered to last analog bracket by the step rate stepping basically, on analog bracket, carries out centering one time through synchronous cylinder clamping, by the sleeve shears steel bushing is held up then and freely rolls in the holder of transportation lift cart V-type; In the free rolling process of steel bushing; All unavoidable run-off the straight, thus the steel bushing of front realization centering misaligns once more or centering is inaccurate, therefore; All need manual work to stir steel bushing at every turn and make it centering once more; Increased operating personnel's live load, and also brought great potential safety hazard aborning, production efficiency is low.
Summary of the invention:
Provide a kind of alternative manually-operated the invention order of the utility model, can realize making the steel bushing automatic centering of inclination, get into the thin coil sleeve secondary centralising device that the coiling machine mandrel is convenient, handling safety is reliable, production efficiency is high.
The utility model is realized through following technical scheme: a kind of thin coil sleeve secondary centralising device is provided; Form by idler gear, both sides tooth bar, steel bushing, sleeve transportation lift cart, it is characterized in that: on sleeve transportation lift cart, set up the secondary centralising device; Be provided with guideway, aligning arm, driving cylinder; Idler gear and the engagement of both sides tooth bar; Both sides tooth bar and both sides guideway are slidingly connected; The both sides tooth bar is connected with the two ends aligning arm with bearing pin through bearing; Drive the end that cylinder is fixed on a side tooth bar; Make two ends keep synchronous cylinder through idler gear through the be slidingly connected aligning arm at two ends of guideway; The two ends aligning arm is connected with the tooth bar end with bearing pin by bearing; Two tooth bars that relatively move drive the guideway slide block and slide, and the two ends aligning arm clamps steel bushing neutralization is separated; The opening degree of two ends aligning arm is confirmed with driving cylinder stroke that by the length specification of steel bushing when minimum position, the aligning arm clamping steel bushing that single face adds backstop makes it centering; When maximum position; Unclamp steel bushing, aligning arm falls down under the effect of coiling machine mandrel automatically, and steel bushing gets into the coiling machine mandrel; Its characteristic also is: the both sides tooth bar is slidingly connected through bolt and both sides guideway; Two ends aligning arm employing roly-poly type baffle plate adds single face backstop and is connected with the tooth bar end with bearing pin by bearing.
The beneficial effect of the utility model is: use this thin coil sleeve secondary centralising device can make the steel bushing centering of inclination accurate; It is convenient, reliable to get into the coiling machine mandrel; Reduced the operation of artificial adjustment steel bushing centering; Improve production operational availability effectively, strengthened operating personnel's safety coefficient.
