Abstract

The utility model relates to a multifunctional torsion guide wheel, comprising torsion guide wheels and guide components, wherein the guide components are mounted at the outlet sides of an 8-rack rolling machine and a 10-rack rolling machine; the torsion guide wheels are mounted on the guide components; the torsion guide wheels comprise an upper guide wheel and a lower guide wheel; and a certain distance is reserved between the upper guide wheel and the lower guide wheel. The guide wheels are mounted on the guide components at the outlet sides of the 8-rack rolling machine and the 10-rack rolling machine, so that a sectional material is twisted for 90 degrees. The multifunctional torsion guide wheel provided by the utility model is applicable to multiple gates; the fault caused by inaccurate installation can be avoided; the storage amount of the guide wheels can be reduced; the simple structure can be realized; and the multifunctional torsion guide wheel is convenient to mount and use.

Description

A kind of multi-functional guide wheel that reverses

Technical field

The utility model relates to a kind of guide and guards, in particular, relates to a kind of multi-functional guide wheel that reverses, and belongs to the steel rolling process design field.

Background technology

In the rolling of sectional iron, guide and guards is installed in before and after the roll pass, helps rolled piece exactly, stably to enter and derive the device of pass by set direction and state, and its Main Function is: correctly rolled piece is imported roll pass; Guarantee rolled piece stably distortion in pass, and obtain desired geometry and size; Successfully with rolled piece by deriving in the pass, prevent curling round the roll; Control or pressure rolled piece reverse or flexural deformation, by certain direction motion.

In the design of guide and guards, decide the size and dimension of the rational working face of guide and guards according to workpiece measurement and shape, thereby make rolled piece can accurately, stably enter and derive roll pass.The selection of guide and guard material needs to select the guide and guard material according to pass shape and application site, requires to have good strength, rigidity, hardness and high temperature abrasion resistance, resistance to impact, anti-chilling and shock heating, to improve service life.

The guide and guards type is divided into sliding guide, rolling guide and guide twisting, selects according to being: a, selected pass schedule, and rolled piece cross dimensions and dimensional accuracy, steel grade and the surface quality passed through are selected; The outfit of the arrangement of b, milling train, frame form and quantity and auxiliary equipment; C, product situation, such as range of product size, dimensional accuracy and concrete operating condition.

In rod, wire rod production line are thick, roll the horizontally disposed milling train of middle employing, the outlet side of even number frame passage milling train, all need to install and enter next passage after guide twisting reverses 90 ° with red steel, because of the size of the red steel of each passage different, during original design, the guide wheel of 8 and 10 two passages is different, causes the standby two kinds of guide wheels of needs, and these two kinds of guide wheels are obscured easily, and the generation that the wrongly installed guide wheel causes fault easily occurs.

The utility model content

Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, provides a kind of and be applicable to a plurality of passages, avoids wrongly installed to cause the multi-functional guide wheel that reverses of fault.

In order to solve above technical problem, the utility model provides a kind of multi-functional guide wheel that reverses, comprise and reverse guide wheel and guide and guard, described guide and guard are installed in the outlet side of 8 and 10 rolling mills, the described guide wheel that reverses is installed in the described guide and guard, the described guide wheel that reverses comprises upper block and lower tumbler, and certain distance is set between described upper block and the lower tumbler.

Further restriction scheme of the utility model is, between described upper block and the lower tumbler distance corresponding with thickness and the distance between the milling train of section bar.

Further, the angle reversed of described guide twisting device is 90 °.

The beneficial effects of the utility model are: a kind of multi-functional guide wheel that reverses described in the utility model, guide wheel is installed in guide and guard at the outlet side of 8 and 10 rolling mills, section bar is reversed 90 °, be applicable to a plurality of passages, avoid wrongly installed to cause fault, reduce the guide wheel quantity in stock, simple in structure, be convenient to install and use.

Description of drawings

The guide twisting that Fig. 1 milling train outlet side described in the utility model is installed;

Fig. 2 is that the multi-functional guide wheel that reverses described in the utility model uses schematic diagram.

The specific embodiment

Embodiment 1

A kind of multi-functional guide wheel that reverses that present embodiment provides, structure comprise and reverse guide wheel and guide and guard as depicted in figs. 1 and 2.

Described guide and guard are installed in the outlet side of 8 and 10 rolling mills, for described guide and guard provide support.

The described guide wheel that reverses is installed in the described guide and guard, comprise upper block and lower tumbler, certain distance is set between described upper block and the lower tumbler, its distance is corresponding with thickness and the distance between the milling train of section bar, the angle that described guide twisting device reverses is 90 °, its role is to section bar from the milling train slotted eye out after, through the twisting resistance of upper and lower guide wheel, section bar is reversed 90 °.

A kind of multi-functional guide wheel that reverses described in the utility model is installed guide wheel in the guide and guard of the outlet side of 8 and 10 rolling mills, and section bar is reversed 90 °, be applicable to a plurality of passages, avoid wrongly installed to cause fault, reduce the guide wheel quantity in stock, simple in structure, be convenient to install and use.

In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.

Claims

1. multi-functional guide wheel that reverses, it is characterized in that, comprise and reverse guide wheel and guide and guard, described guide and guard are installed in the outlet side of 8 and 10 rolling mills, the described guide wheel that reverses is installed in the described guide and guard, the described guide wheel that reverses comprises upper block and lower tumbler, and certain distance is set between described upper block and the lower tumbler.

2. a kind of multi-functional guide wheel that reverses according to claim 1 is characterized in that, between described upper block and the lower tumbler thickness and the distance between the milling train of distance and section bar corresponding.
