Description
Technical field
The utility model relates to rolling mill guiding accessory field, particularly relates to the guide and guard of a kind of pinch roll import and export.
Background technology
Guide and guard just refer in rolling of sectional iron process, are arranged on before and after roll pass and help rolled piece exactly, stably enter by set direction and state and derive the device of roll pass.
The effect of guide and guard in wire production:
(1) correct rolled piece is imported roll pass;
(2) ensure the distortion that rolled piece is stable in pass, and obtain required geometry and size;
(3) successfully rolled piece is derived by pass, prevent curling round the roll;
(4) control or force rolled piece to reverse or flexural deformation, moving by certain direction;
(5) shaped steel of any section configuration of rolling, almost all will use guide and guards in the import of all rolls with outlet.Its effect makes rolled piece according to required state turnover pass, can ensure that rolled piece is rolled by namely fixed deformation condition.Although hole type design is reasonable, if the design of guide and guards or improper use, qualified product can not be shut out, and may cause to scrape and cut rolled piece, squeeze steel, curling round the roll, even cause roll breakage or serious equipment breakdown and personal injury.
The guide and guard of existing pinch roll import and export, as shown in Figure 1, be sliding friction between its outlet guide and rolled piece, the inner wall abrasion amount of rolled piece outlet guide is very large, and the service life of outlet guide is short, guide and guard weak effect.
Utility model content
The purpose of this utility model is to provide the guide and guard of a kind of pinch roll import and export, to solve the problems of the technologies described above.
Technical problem to be solved in the utility model realizes by the following technical solutions:
The guide and guard of a kind of pinch roll import and export, it is characterized in that: comprise one group of pinch roll, pinch roll side arranges inlet guide, opposite side arranges outlet guide, the curved bend tune of described outlet guide arranges guide roller component and lower guide roll assembly, described upper guide roller component is arranged on the upper stress point of outlet guide inwall, and described lower guide roll assembly is arranged on the lower stress point of outlet guide inwall; Described upper guide roller component comprises the deflector roll bracket be enclosed within outside outlet guide, described deflector roll bracket is provided with guide roller axis, guide roller axis is provided with outlet deflector roll by duplex bearing, described outlet guide has guide roller grooves, the roll surface of described outlet deflector roll inserts in guide roller grooves, and described upper guide roller component has identical structure and mounting means with lower guide roll assembly.
After the roll surface insertion guide roller grooves of outlet deflector roll, roll surface is concordant with the inwall of outlet guide or slightly exceed the inwall of outlet guide, when rolled piece is derived from outlet guide, rolled piece contacts with the roll surface of outlet deflector roll, be rolling friction between rolled piece and outlet deflector roll, the wearing and tearing between rolled piece and outlet guide inwall can be reduced.
Described guide roller axis upper end is provided with grease fitting, and grease fitting lower end connects the internal oil channel arranged in guide roller axis, and described guide roller axis lower end is fastened on deflector roll bracket by locking nut.
Described deflector roll bracket is " C " type bracket, and outlet deflector roll is arranged on the opening part of deflector roll bracket.
Be provided with separator between two bearings of described duplex bearing, separator connects internal oil channel.
Described deflector roll bracket screws in bolt respectively from different directions on the body of outlet guide, is fixed on the outer wall of outlet guide by deflector roll bracket by bolt.
The beneficial effects of the utility model are:
The pinch roll import and export guide and guard that the utility model provides, compared with the pinch roll import and export guide and guard of traditional structure, outlet guide adds adjustable on guide roller component and lower guide roll assembly, make to become rolling friction between rolled piece and outlet guide, go up guide roller component and lower guide roll assembly simultaneously and be separately positioned on main stress point in outlet guide, effectively improve guide and guard effect and reduce the wear extent of guide and guard inwall.
