Description
Technical Field
The utility model relates to a rough rolling device specifically indicates a rough rolling device is used in band steel production.
Background
The flat steel is steel with a width of 12-300mm, a thickness of 3-60mm, a rectangular section and a slightly truncated edge. The flat steel can be finished steel products, and can also be used as a blank of a welded pipe and a thin slab for a pack-rolled thin plate. Roughing is a basic processing procedure in the production process of flat steel, and a two-roller rolling mill is generally adopted in a roughing device for flat steel production at present. The prior two-roller rolling mill has the following defects when the flat steel is roughly rolled: 1) in order to adapt to the rolling of flat steel with different thicknesses, the conventional two-roller rolling mill is generally provided with a roller fixing device, and the other roller is movably installed, so that although the rolling thickness can be timely adjusted according to different types of the flat steel, the movably installed rolling roller is easily influenced by an installation mechanism when rolling the steel, and the rolling effect is easy to be unstable and even damaged; 2) the two-roll mill is characterized in that the two rolling rolls are driven by a meshing gear set arranged at the outer end parts of the two rolling rolls generally, and a driving stress point is positioned at the outer end parts of the two rolling rolls, so that the stability of relative motion between the two rolling rolls is insufficient, and the rolling quality of the flat steel is easy to shift.
Consequently, design a section and can realize the band steel rolling of multiple model on the basis of fixed point installation to effectively improve the rolling effect of band steel, and can effectively ensure the stability of rolling roller at the operation in-process, thereby further effectively improve the band steel production of the rolling effect of band steel and use rough rolling device to be the utility model discloses a research purpose.
Disclosure of Invention
To the technical problem that above-mentioned prior art exists, the utility model provides a band steel production is with rough rolling device, this band steel production is with rough rolling device can effectively solve the technical problem that above-mentioned prior art exists.
The technical scheme of the utility model is that:
a roughing device for flat steel production comprises a rack, a two-roller rolling mechanism and a driving mechanism, wherein the two-roller rolling mechanism comprises an upper pressing roller and a lower pressing roller which are installed on the rack in a fixed-point rotating mode, corresponding convex edges are correspondingly arranged on two sides of the upper pressing roller and the lower pressing roller in an integrated mode respectively, and the outer end faces of the convex edges arranged on the two sides of the upper pressing roller and the lower pressing roller are respectively arranged in a mutually meshed tooth shape; the upper compression roller is provided with at least two corresponding rolling sections in a step shape, and the lower compression roller is arranged in a regular cylindrical shape.
The driving mechanism comprises a driving motor and a speed reducer connected to the output end of the driving motor in a transmission mode, and one end of the lower pressing roller is connected to the output shaft end of the speed reducer in a transmission mode through a corresponding driving connecting shaft.
The driving motor is supported and installed on the corresponding supporting platform.
The upper compression roller is provided with three corresponding rolling sections in a step shape.
The utility model has the advantages that:
1) the utility model discloses an it is provided with two at least corresponding rolling sections that the step form is gone up the compression roller, and regular cylindrical shape is set to the lower compression roller. Through setting to the lower compression roller of regular form and the last compression roller cooperation that is provided with the rolling section of multistage, be equivalent to the last compression roller cooperation of lower compression roller and a plurality of different models, only need effectively adjust the rolling of the band steel of feed position alright realization different models according to the model of band steel, it is very convenient. The flat steel rolling device has the advantages that the flat steel rolling of various models can be realized on the basis of fixed-point installation, the convenience degree of rough rolling of the flat steel is improved, and the rolling effect of the flat steel is effectively improved.
2) The utility model discloses go up the both sides of compression roller and lower compression roller and become the corresponding protruding edge that is provided with of integration respectively, go up the outer terminal surface on the protruding edge that compression roller and lower compression roller both sides were equipped with and set the flute profile of intermeshing respectively. Through the setting on the protruding edge of integration, effectively will drive stress point evenly distributed in the both sides of last compression roller and lower compression roller, most importantly protruding edge itself and last compression roller and have sufficient wholeness and connection stability down between the compression roller, can effectively ensure the stability of rolling roller at the operation in-process to further effectively improve the rolling effect of band steel.
