Abstract

The utility model relates to an anti-piling up steel guide and guard device for H-shaped steel. The guide and guard device comprises upper guide plates, lower guard plates and blocks, wherein the upper guide plates are matched with the lower guide plates to form a set of guide and guard; and the blocks are connected to end parts of the upper guide plates and the lower guard plates. Due to the blocks, a problem of steel piling up due to warping and buckling of a rolled piece is prevented, so rolling stability is improved, thereby providing the anti-piling up steel guide and guard device for H-shaped steel with obvious economic and social benefits.

Description

The anti-heap steel of H shaped steel guide and guards

Technical field

The utility model relates to field of metallurgy, particularly the anti-heap steel of a kind of H shaped steel guide and guards.

Background technology

H shaped steel guide and guards is the important accessory in milling train, and it is for guiding rolled piece correctly to pass in and out the device of pass.As shown in Figure 1, this device is generally comprised of following parts: guide plate 1, is positioned at pass 3(referring to Fig. 4) before and after both sides, guide plate before pass 31 induction rolled piece enters pass, the guide plate 1 after pass 3 can prevent that rolled piece from forming bending at horizontal plane; Defend plate 2, be positioned at the upper and lower after pass 3, can prevent that rolled piece from producing collaring.

In the production line of H shaped steel, include many milling trains, between different milling trains, rely on described guide and guards transition, the transverse shifting owing to rolling off the production line on milling train and the roll of each rolling pass are adjusted up and down, must guarantee that spacing distance between the guide and guards of adjacent milling train is in 50 millimeter.But blank is subject to the impact of the factors such as technique adjustment, blank section, temperature difference change in the operation of rolling, easily occurs nose, discount, partially first-class phenomenon, therefore, if guide and guards excesssive gap, easily cause blank to get out guide and guard gap, cause heap steel, thereby cause the accident.

Utility model content

The purpose of this utility model is to overcome the defect of existing guide and guards excesssive gap, thereby a kind of guide and guards that can stop because of rolled piece end bending and the caused heap steel of discount phenomenon is provided.

To achieve these goals, the utility model provides the anti-heap steel of a kind of H shaped steel guide and guards, comprise upper guide plate 1, under defend plate 2 and block 3; Wherein,

Described upper guide plate 1 with under defend plate 2 and be used in conjunction with, forms one group of guide and guard, described block 3 be connected to described upper guide plate 1 and under defend the end of plate 2.

In technique scheme, described block 3 for afterbody become described in circular-arc strip block the width of block 3 be less than upper guide plate 1 or under defend 1/2nd of plate 2 width.

In technique scheme, when mounted, the block 3 of adjacent guide and guards is staggered to adjacent guide and guards.

The utility model has the advantage of:

Anti-heap steel guide and guards of the present utility model, due to the existence of block, can be stopped because of rolled piece end bending and the caused heap steel of discount phenomenon, and then improves rolling stability, has significant economic benefit and social benefit.

The specific embodiment

Now the utility model will be further described by reference to the accompanying drawings.

With reference to figure 2(a) and Fig. 2 (b), H shaped steel guide and guards of the present utility model comprise upper guide plate 1, under defend plate 2 and block 3; Wherein, described upper guide plate 1 with under defend plate 2 and be used in conjunction with, forms one group of guide and guard, described block 3 be connected to described upper guide plate 1 and under defend the end of plate 2.

Below the associated components in this device is described further.

With reference to figure 3, described block 3 becomes circular-arc strip block for afterbody; In the present embodiment, as shown in Figure 2, the width of described block 3 (part shown in B in Fig. 3) is less than 1/2nd of upper guide plate 1 width, and its length (part shown in L in Fig. 3) is 300mm.

Below the installation process of H shaped steel guide and guards of the present utility model is described.

With reference to figure 4, H shaped steel guide and guards is arranged on the both sides of milling train (part as shown in semicircle in Fig. 4), as shown in Figure 5, between adjacent bundle machine by described guide and guards transition.When mounted, the block 3 of adjacent guide and guards is adjacent guide and guards staggered (as shown in the numeral 70 in numeral 60 and Fig. 6 in Fig. 5), and adjacent two blocks overlap in rolling direction.Fig. 6 is the enlarged drawing of adjacent guide and guards alternating share, Fig. 7 is the top view of adjacent guide and guards alternating share, from these two figure, can find out, existence due to block 3, can stop because of rolled piece end bending and the caused heap steel of discount phenomenon, and then raising rolling stability, there is significant economic benefit and social benefit.

It should be noted last that, above embodiment is only unrestricted in order to the technical solution of the utility model to be described.Although the utility model is had been described in detail with reference to embodiment, those of ordinary skill in the art is to be understood that, the technical solution of the utility model is modified or is equal to replacement, do not depart from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
