Abstract
一种型钢轧矫机，包括一对水平辊和一对立辊，其特征在于：还包括一对矫直辊且设置在轧制方向的出口侧，所述矫直辊与所述立辊相对于轧制线对称布置且转动轴线平行。本实用新型通过设置矫直辊可以一次完成轧件的轧制和矫直，克服了现有技术容易出现型材镰刀弯及内并外扩现象，提高了产品质量，降低了设备数量和设备投资，不仅降低了运行成本，节约了能源消耗，而且提高了生产效率，并具有结构简单，操作方便的特点。
A profile steel rolling and leveling machine, comprising a pair of horizontal rolls and a pair of vertical rolls, characterized in that it also includes a pair of straightening rolls and is arranged on the exit side of the rolling direction, and the straightening rolls are opposite to the vertical rolls The rolling lines are arranged symmetrically and the axes of rotation are parallel. The utility model can complete the rolling and straightening of the rolled piece at one time by setting the straightening rollers, which overcomes the phenomenon of sickle bending and internal and external expansion of the profile in the prior art, improves the product quality, reduces the number of equipment and equipment investment, It not only reduces the operating cost and saves energy consumption, but also improves the production efficiency, and has the characteristics of simple structure and convenient operation.
Description
Technical field
The utility model relates to a kind of milling train, is specifically related to a kind of shaped steel and rolls strong machine.
Background technology
Various shaped steel such as H shaped steel, I-steel and rail use the universal mill roll forming usually.Existing universal mill (referring to Fig. 1) is made up of an a pair of horizontal roller 1 and an opposite roller 2, and wherein horizontal roller is a drive roll, and edger roll is a driven roll.Because the temperature when rolling of sectional iron very high (generally about 900 degree), the drafts of universal mill is bigger, and several kinds of defectives below the section bar that rolls out occurs easily: the bending on (1) vertical direction deserves to be called down curved or warpage again; (2) bending on the horizontal direction is commonly called as camber; (3) in and extend out phenomenon.Warpage is usually through being able to aligning on straightener after the supercooling; But for camber, the straightener that is using does not at present have special arrangement to align, as wants to improve the quality of products; Need other increase equipment; And through cooled shaped steel temperature lower (generally below 80 ℃), the required straightening force of aligning camber is greater than the required straightening force of aligning warpage, and weight of equipment is big; In addition, for interior and extend out phenomenon, even, also be difficult to reach ideal effect through aligning.
The utility model content
The purpose of the utility model be to provide a kind of can prevent section bar occur camber and in and the shaped steel that extends out phenomenon roll strong machine.
The purpose of the utility model is to realize like this; A kind of shaped steel rolls strong machine; Comprise an a pair of horizontal roller and an opposite roller, it is characterized in that: also comprise a pair of smoothing roll and be arranged on the outlet side of rolling direction, said smoothing roll is parallel with respect to roll line symmetric arrangement and pivot center with said edger roll.
Above-mentioned smoothing roll and edger roll and rolled piece contact point to the distance of roll line equate and the roller footpath of said smoothing roll less than the roller footpath of said edger roll.
In order to prevent to depart from roll line in the operation of rolling, be provided with guide plate between the edger roll of rolled piece homonymy and the smoothing roll.
During rolled section steel, horizontal roller drives rolled piece and moves forward, and the effect of frictionally drives edger roll and smoothing roll rotates, and realizes rolling straightening function.
The utlity model has following beneficial effect, the utility model can once be accomplished the rolling of rolled piece and aligning through smoothing roll is set, overcome prior art occur easily the section bar camber and in and extend out phenomenon; Improve product quality, reduced number of devices and equipment investment, not only reduced operating cost; Practiced thrift energy resource consumption; And improved production efficiency, and have simple in structure, convenience operation.

Fig. 4 is Fig. 3 schematic perspective view.
The specific embodiment
Embodiment, a kind of shaped steel rolls strong machine, comprises a pair of horizontal roller 1, an opposite roller 2 and a pair of smoothing roll 3, and smoothing roll 3 is arranged on the outlet side of rolling direction, and smoothing roll 3 is parallel with respect to roll line symmetric arrangement and pivot center with edger roll 2.Smoothing roll 3 equates with the distance of rolled piece contact point to roll line that with edger roll 2 the roller footpath of smoothing roll 3 is less than the roller footpath of edger roll 2.Be provided with guide plate 4 between the edger roll 2 of rolled piece homonymy and the smoothing roll 3.
During rolled section steel, horizontal roller 1 drives rolled piece and moves forward, and the effect of frictionally drives edger roll 2 and rotates with smoothing roll 3, once accomplishes the rolling of rolled piece and aligning.
Claims (3)
1. a shaped steel rolls strong machine; Comprise an a pair of horizontal roller (1) and an opposite roller (2); It is characterized in that: also comprise a pair of smoothing roll (3) and be arranged on the outlet side of rolling direction, said smoothing roll (3) is parallel with respect to roll line symmetric arrangement and pivot center with said edger roll (2).
2. shaped steel as claimed in claim 1 rolls strong machine, it is characterized in that: said smoothing roll (3) and edger roll (2) and rolled piece contact point to the distance of roll line equate and the roller footpath of said smoothing roll (3) less than the roller footpath of said edger roll (2).
3. shaped steel as claimed in claim 1 rolls strong machine, it is characterized in that: be provided with guide plate (4) between edger roll of rolled piece homonymy (2) and the smoothing roll (3).
