Abstract
The utility model relates to an improvement of a roll system connecting structure of a cold rolling mill and provides a cold rolling mill which not only ensures the roll change quality and efficiency, but also reduces roll change cost and equipment investment. The cold rolling mill comprises an upper support roll, a lower support roll, an upper work roll, a lower work roll, and bearing seats used for connecting the upper work roll and the lower work roll with a machine body of the cold rolling mill, wherein an elastic floating support mechanism is disposed between the bearing seats of the upper work roll and the lower work roll, and the elastic floating support mechanism comprises axle pins, bolts, springs and support rods. Due to the fact that the cold rolling mill is innovatively provided with the elastic floating support mechanism disposed between the upper work roll and the lower work roll, the contact between the surfaces of the upper work roll and the lower work roll can be effectively avoided when the upper work roll and the lower work roll break away from the machine body. Furthermore, when the novel elastic floating support mechanism is in use, not only trace amount of movement between the upper work roll and the lower work roll is guaranteed, but also effective mutual position accuracy of the upper work roll and the lower work roll after breaking away from the machine body is ensured.
Description
Technical field
It is the improvement of syndeton that the utility model relates to the roller of cold-rolling mill.
Background technology
General cold rolling mill work roller roller replacing mode has two kinds: a kind of is to utilize special-purpose roll changing carriage to change working roll, another kind be between the upper working rolls and lower working rolls and between bottom working roll and lower support roller artificial place cushion block then by the backup roll change cart pull out backing roll simultaneously working roll also be drawn out of.Wherein first kind of mode need utilize special-purpose roll changing carriage to change working roll, not only increases production cost and makes the corresponding work roll roll-changing equipment, also wasted the production time; The second way has increased production time at the artificial cushion block of placing between the upper working rolls and lower working rolls, between bottom working roll and the lower support roller.
The utility model content
The utility model provides a kind of and when guaranteeing to guarantee roll change quality and efficient, can reduce the roll change cost to above problem, the cold-rolling mill that minimizing equipment drops into.
The technical scheme of the utility model is: said cold-rolling mill comprises upper and lower backing roll, upper and lower working roll, and be used for upper and lower working roll is connected the bearing block on the said cold-rolling mill body;
Be provided with the elastic floating supporting mechanism between the bearing block of said upper and lower working roll; Said elastic floating supporting mechanism comprises pivot pin, screw, spring and support bar;
The both sides of said top working roll bearing block bottom surface offer the blind hole perpendicular to horizontal plane respectively;
The both sides of said bottom working roll bearing block end face offer the through hole perpendicular to horizontal plane respectively, and the middle part of said through hole is provided with step;
The said blind hole of homonymy and said through hole concentric;
The center of said pivot pin is provided with stepped hole, and said stepped hole comprises bottom macropore and top connecting hole;
Said support bar shaft top is provided with small stair circle portion, bottom and is provided with big step circle portion, and the shaft end face is provided with screwed hole;
The cylindrical of said pivot pin is connected with the interior slyness of the said through hole of the interior circle of the said blind hole of top and below respectively movingly;
The big step circle portion of said support bar and said through hole sliding connection;
Said spring housing is located at the small stair circle portion of said support bar and is in the bottom macropore of said pivot pin; Make spring constraint between the end face of the end face of said through hole middle bench and said bottom macropore;
Said screw gets into the screwed hole that connects said shaft end face from said pivot pin end face connecting hole.
End face at said through hole middle bench also is provided with a back-up ring, is used to contact the bottom surface of said spring.
Also comprise sealing ring, said sealing ring is located at the place, aperture of said bottom working roll bearing block end face through hole.
The utility model novelty ground proposes (on perpendicular to the horizontal plane direction, to be the strong point with the lower roll promptly, to utilize elastic force that top roll " floating holder " is lived, cause the roll surface damage to prevent the contact of upper and lower roll face in that the elastic floating supporting mechanism is set between the upper and lower roll; Be equivalent to bear the gravity of roller arrangement) through four springs; Can, upper and lower roll effectively avoid the contact between the upper and lower roll roll surface when breaking away from body respectively; And the elastic floating supporting mechanism of the utility model can guarantee to have trace movement between the upper and lower roll when work, can guarantee that again upper and lower roll is breaking away from the mutual alignment precision of still remaining valid behind the body.The utility model need not to increase special-purpose roll-changing equipment and reduces production costs and economize labor time.
