Utility model content
The technical problem that the utility model solves is to provide a kind of double deflector roll guide and guards for rolling line bend place, can realize rolled piece correctly, smoothly by the bypass bend position of rolling line, prevent from rolled piece and guide groove from producing to slidingly contact, reduce the probability that rolled piece scratches, improve rolled piece product quality.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of double deflector roll guide and guards for rolling line bend place, comprise deflector roll, bearing, space collar, guide roller axis, conduit box body, back-up ring, conduit, shaft end pressure plate, it is characterized in that, described deflector roll is arranged on guide roller axis by bearing, guide roller axis is arranged on conduit box body, back-up ring is arranged on guide roller axis between conduit box body and bearing inner race, and space collar to be arranged on guide roller axis between two bearing inner races; Described shaft end pressure plate is inserted in the groove that guide roller axis is provided with, and is fastened on conduit box body by bolt, spring washer; Described conduit inserts in conduit box body, by clamping screw, fastening nuts.
Described conduit outside be circumferentially provided with circular positioning step, this double deflector roll guide and guards be fixed on guide and guard take by bearing pin and cover, and can 360 degree of rotations; Inside is provided with straight channel Φ d and goes directly conduit box body close to double deflector roll region, and rolled piece entrance is set to horn mouth, horn mouth maximum outside diameter Φ D 10-30mm larger than rolled piece overall diameter.
Described catheter interior straight channel diameter of phi d is more bigger than rolled piece overall diameter.
Distance L between described two deflector rolls is adjustable, and L will be slightly less than the diameter of phi d of catheter interior straight channel.
Described guide roller axis center is provided with oil guide groove, and both ends are provided with gas thread hole.
Described conduit box body is provided with gas thread hole and inner chamber spray orifice.
Described deflector roll adopts high-wearing feature material to make.
Compared with prior art, the beneficial effects of the utility model are:
1) rolled piece can be realized correctly, smoothly by the bypass bend position of rolling line, prevent rolled piece and guide groove from producing and slidingly contact, rolled piece is stable, fluctuate little, reduce the probability that rolled piece scratches, improve rolled piece product quality;
2) structure simple, be convenient to install and adjust, be specially adapted to the deflector roll guide and guards at rolling line bend position.
