Abstract
The utility model provides a kind of entrance rolling two independent portal frame, relate to metallurgical steel rolling field, comprise roll and two groups of guide assemblies, described two groups of guide assemblies are installed respectively by independently portal frame, portal frame lower end is arranged on base, and described portal frame is connected by longitudinal adjusting mechanism with between guide assembly, and described base is horizontally arranged with worm screw, worm screw and two groups of guide assemblies, by threaded engagement, described base are also provided with horizontal guide groove.Before and after the utility model can carry out guide assembly, the independence of (longitudinal direction), left and right (transverse direction) regulates, before and after guide assembly can be undertaken by longitudinal adjusting mechanism in independently portal frame, (longitudinal direction) regulates, and guide assembly can carry out left and right (transverse direction) adjustment by worm screw on base.
Description
Technical field
The utility model relates to metallurgical steel rolling field, particularly relates to the two independent portal frame of a kind of entrance rolling.
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.
When generally walking two-wire on short stress rolling mill, because the adjustable crossbeam of short stress rolling mill only uses one, we are adopt dual bed in design guide and guard, and dual bed is installed two cover guide and guard, the mounting structure of existing rolling guide (as shown in Figure 1 and Figure 2) is designed with many deficiencies.Such as rolling guide can only carry out lateral adjustments on base, according to the change of roll diameter of roller, can not carry out longitudinal adjustment to guide and guard, when the nose cone of guide and guard is away from roll, can not effectively ensure the guide and guard effect of discharging.
Utility model content
The purpose of this utility model is to provide a kind of entrance rolling two independent portal frame, 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 two independent portal frame of a kind of entrance rolling, it is characterized in that: comprise roll and two groups of guide assemblies, described two groups of guide assemblies are installed respectively by independently portal frame, portal frame lower end is arranged on base, described portal frame is connected by longitudinal adjusting mechanism with between guide assembly, described base is horizontally arranged with worm screw, and worm screw and two groups of guide assemblies, by threaded engagement, described base are also provided with horizontal guide groove.
Described longitudinal adjusting mechanism comprises slide rail and glidepath, and spacing adjustment is carried out respectively by upper slide rail and glidepath in the upper and lower two ends of guide assembly.
Described guide assembly and the nearer side of roll are connected with nose cone, and taper is arranged in nose cone front end, can stretch in the gap between two rolls, better shields and sustain rolled piece and enters roll.
Mainly in process of production, when roll is in most big roller footpath, guide and guard can be moved backward in forward and backward adjustment, and when roll is in most pony roll footpath, guide and guard can be moved forward, cause guide and guard keep from roll all the time close to distance.Left and right adjustment mainly solves guide and guard and installs after crossbeam, when the pass of guide and guard and the pass of roll have a some deviation, is finely tuned by the left and right transverse-moving mechanism of guide and guard, makes the pass of the pass of guide and guard and milling train just in time point-blank.Have certain spacing because of in the middle of deflector roll and roll, we, at a deflector roll and roll medium design nose cone, are shielded and sustain by nose cone after making material shape cross deflector roll and better enter roll.
The beneficial effects of the utility model are:
Before and after the utility model can carry out guide assembly, the independence of (longitudinal direction), left and right (transverse direction) regulates, before and after guide assembly can be undertaken by longitudinal adjusting mechanism in independently portal frame, (longitudinal direction) regulates, and guide assembly can carry out left and right (transverse direction) adjustment by worm screw on base.
