Abstract
The utility model discloses a guide plate for rolling round steel, which comprises a guide plate body and an abrasion-resistant alloy plate, wherein the middle part of the guide plate body is longitudinally provided with an abrasion-resistant alloy plate mounting slot; the abrasion-resistant alloy plate is detachably arranged in the abrasion-resistant alloy plate mounting slot; and the surface of the abrasion-resistant alloy plate and the surface of the guide plate body are parallel with each other. When the guide plate takes the guide effect, the abrasion-resistant alloy plate directly contacts with a hot rolling square billet; the abrasion-resistant alloy plate has high hardness and good abrasion resistance, and therefore, the service life of the guide plate is greatly prolonged. Moreover, after the abrasion-resistant alloy plate is abraded, the abrasion-resistant alloy plate is directly replaced on the guide plate body without detaching the guide plate body from a lower beam, which is not only convenient but also is quick, greatly shortens maintenance time and maintenance cost and simultaneously improves production efficiency.
Description
Technical field
The utility model relates to a kind of steel rolling equipment parts, relates in particular to a kind of guide plate that is used for milling round steel.
Background technology
Important ring in the milling round steel is that the square billet of hot rolling is carried fast by conveying roller, introduce between topping roll and the bottom roll by the guide plate guiding and with blank, press bundle by topping roll and bottom roll, square billet is rolled into the round steel of required form, its centering guide plays important guiding function, is the critical component of round steel forming quality.
Guide plate is an ironcasting, after guide plate is installed on the sill, two guide plates are one group, and it is laterally mobile to drive guide plate by sill, and the square billet that conveying roller is carried is introduced between the top and bottom rolls, but because of the square billet transporting velocity of hot rolling fast, and the friction between the guide plate is serious, and often the middle part with guide plate vertically grinds a groove, and the square billet position that causes being introduced between the top and bottom rolls is inaccurate, the round steel cylindrical that shuts out is not round, and product quality descends.Therefore, often need the guide surface of guide plate is repaired.In the prior art, the guide plate after will wearing and tearing usually from sill dismounting down, built-up welding one deck wear resistant alloy material in the groove of wearing and tearing then, and the guide plate after the built-up welding carried out Surface Machining is utilized its guide plate that is worn once more.But adopt the structure of built-up welding one deck wear-resistant alloy layer on the guide plate of wearing and tearing to have following deficiency: one, guide plate needs to pull down from sill, through built-up welding, metalworking, and then installs, and the maintenance of equipment time is long, seriously affects production; Two, maintenance cost of labor and rehabilitation cost height are uneconomical.
The utility model content
At the prior art above shortcomings, the utility model provides a kind of realization short maintenance time, and cost is low, the guide plate that is used for milling round steel that production efficiency is high.
The guide plate that is used for milling round steel that the utility model provides comprises guide plate body and antifriction alloy plate, the middle part of described guide plate body vertically is provided with antifriction alloy plate mounting groove, described antifriction alloy plate is dismountable to be installed in the antifriction alloy plate mounting groove, and the plate face of antifriction alloy plate is equal with the plate face of guide plate body.
Further, the front end of described antifriction alloy plate mounting groove fixedly installs inserted block, the buckling groove that the front end setting of described antifriction alloy plate matches with inserted block, and fixedly connected with the guide plate body by clamping screw in the rear end of antifriction alloy plate.
The beneficial effects of the utility model: guide plate of the present utility model adopts guide plate body and the combination of antifriction alloy plate, what the antifriction alloy plate was detachable is installed in the vertical antifriction alloy plate mounting groove that is provided with in guide plate body middle part, guide plate is when playing guiding function, the antifriction alloy plate directly contacts with the hot rolling square billet, the hardness of antifriction alloy plate is big, anti-wear performance is good, has prolonged the service life of guide plate greatly; And after the wearing and tearing of antifriction alloy plate, need not the guide plate body is pulled down from sill, directly on the guide plate body, the antifriction alloy plate is more changed, both convenient, quick again, shortened maintenance time and maintenance cost greatly, improved production efficiency simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the guide plate structural representation in use that is used for milling round steel of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.
Fig. 1 is a structural representation of the present utility model, and as shown in the figure: the guide plate that is used for milling round steel comprises guide plate body 1 and antifriction alloy plate 2.The middle part of guide plate body 1 vertically is provided with antifriction alloy plate mounting groove 3, antifriction alloy plate 2 dismountable being installed in the antifriction alloy plate mounting groove 3, and the plate face of antifriction alloy plate 2 is equal with the plate face of guide plate body 1.
In the present embodiment, the front end of antifriction alloy plate mounting groove 3 fixedly installs inserted block 4, the buckling groove 5 that the front end setting of antifriction alloy plate 2 matches with inserted block 4, and fixedly connected with guide plate body 1 by clamping screw 6 in the rear end of antifriction alloy plate 2.When on guide plate body 1, antifriction alloy plate 2 being installed, the rear end of antifriction alloy plate 2 from antifriction alloy plate mounting groove 3 slided into forward, the buckling groove 5 of antifriction alloy plate 2 is fastened on the inserted block 4, and is fixed on the guide plate body 1 with the rear end of clamping screw 6 with antifriction alloy plate 2.
When using this guide plate that is used for milling round steel, as shown in Figure 2, the bottom of guide plate body 1 is installed on the sill 7, and the arcwall face up and down of guide plate body 1 front end is corresponding with topping roll 8 and bottom roll 9 respectively.When conveying roller is delivered to the guide plate place with the square billet 10 of hot rolling, two guide plates are introduced between topping roll 8 and the bottom roll 9, and 10 of the square billets of hot rolling contact with antifriction alloy plate 2 on the guide plate body 1, and the hardness of antifriction alloy plate 2 is big, anti-wear performance is good, has prolonged the service life of guide plate greatly.After antifriction alloy plate 2 wearing and tearing, screw out clamping screw 6, antifriction alloy plate 2 is withdrawed from from guide plate body 1, can continue again to use after installing new antifriction alloy plate 2.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
