Abstract
The utility model discloses a working roll door locking plate of a horizontal rolling mill. The working roll door locking plate is fixed to an archway boss through bolts, and comprises a door locking plate body and stainless steel lining plates with the hardness larger than that of the door locking plate body and lower than that of the bolts. The lining plates are fixedly arranged on the front surface of the door locking plate body through screws, and identical kidney-shaped holes used for the bolts to penetrate are formed in the lining plates and in the door locking plate body. Due to the fact that the door locking plate body and the lining plates are independent, the lining plates serving as door locking plate working faces are low in cost, simple in installation mode, low in weight and convenient to maintain, after the working faces are crushed, what is needed is to replace the lining plates on the rolling mill, overall replacement is needless, and maintenance cost and time are saved. Besides, due to hardfacing and rust protection on the rear surface of the door locking plate body, service life of the door locking plate body is prolonged.
Description
Technical field
The utility model relates to operation roll of mill, more particularly, relates to a kind of horizontal mill working roll plate of locking a door.
Background technology
At present, the plate of locking a door of the anti-roll axial displacement of the horizontal mill working roll in the zone of hot rolling mill roughing both at home and abroad is all the iron block that adopts an integral body, is fixed by bolts on the memorial archway boss, realizes opening the action of closing by oil cylinder.
In the time will changing working roll, oil cylinder retracts opens the plate of locking a door; When normal steel rolling, oil cylinder is stretched and is closed the latching door plate.In order to realize action, the bolt that the plate of fixedly locking a door is used must and be locked a door between plate and is had gap, and when normal steel rolling, working roll has axial displacement by bolt and gap between the plate elimination of locking a door.While as abnormal, causing the roll axial force excessive, the protectiveness fracture can occur in bolt.Therefore, the plate of locking a door is subject to the impact of roll axial force for a long time, can make whole bolt contact-making surface run-off the straight conquassation, causes when axial force is normal, because contact-making surface inclination king-bolt discontinuity often ruptures.The impact of various pipes (refer to oil pipe and control spool etc.) can't be multiple in machine maintenance on every side because be subject to for the plate of locking a door of conquassation, can only integral body be changed, and wastes time and energy.
The utility model content
The purpose of this utility model aims to provide a kind of horizontal mill working roll plate of locking a door, and can realize multiple in machine maintenance rapidly.
This horizontal mill working roll plate of locking a door, be bolted on the memorial archway boss, comprise that the plate body of locking a door, hardness are higher than locking a door plate body and lower than the stainless steel liner plate of bolt, liner plate is fixedly arranged on the front surface of the plate body of locking a door by screw, and has the mounting hole that the described bolt of identical confession passes on liner plate and the plate body of locking a door.
Described front surface of locking a door the plate body is provided with the installation groove, and described liner plate is inlayed and is located in corresponding installation groove, and the liner plate front surface is higher than the front surface of the plate body of locking a door.
Be coated with glue layer on the contact-making surface of described liner plate and installation groove.
On the rear surface of the described plate body of locking a door, built-up welding has a stainless steel antirust coat.
The horizontal mill working roll of the present utility model plate of locking a door is bolted on the memorial archway boss, comprise that the plate body of locking a door, hardness are higher than locking a door plate body and lower than the stainless steel liner plate of bolt, liner plate is fixedly arranged on the front surface of the plate body of locking a door by screw, and has the mounting hole that the described bolt of identical confession passes on liner plate and the plate body of locking a door.Because lock a door plate body and liner plate are two independently parts, liner plate as the plate working face of locking a door is cheap, and installation form is simple, weight is lighter, easy to maintenance, after the working face conquassation, as long as changing liner plate at machine can recover normally, without integral replacing, to have saved maintenance cost and time, and by the plate body of locking a door is carried out to the antirust processing of built-up welding, to improve its service life.
The accompanying drawing explanation
In the utility model, identical Reference numeral means identical feature all the time, wherein:
Fig. 1 is the scheme of installation of the plate of locking a door of the present utility model;
Fig. 2 is the structural representation of the plate of locking a door of the present utility model.
The specific embodiment
Further illustrate the technical solution of the utility model below in conjunction with drawings and Examples.
Refer to shown in Fig. 1～Fig. 2, horizontal mill working roll of the present utility model lock a door plate same as the prior art be, equally also by bolt 1, be fixed on memorial archway boss 2, differently with it be, this plate of locking a door comprises the plate body 3 of locking a door, hardness is higher than locking a door plate body 3 and lower than stainless steel liner plate 4 these two parts independently of bolt 1, wherein, liner plate 4 is fixedly arranged on the front surface of the plate body 3 of locking a door by a plurality of screws 5, and have the mounting hole 6 that the described bolt 1 of identical confession passes on liner plate 4 and the plate body 3 of locking a door, when the oil cylinder 7 that is connected in plate body 3 one ends of locking a door moves, can drive the whole plate of locking a door does to move around by mounting hole 6.
As an embodiment, comprise two of upper and lower setting at the liner plate 4 shown in Fig. 1～Fig. 2, and described front surface of locking a door plate body 3 is provided with upper and lower two groove 8 is installed, two blocks of liner plates 4 are inlayed respectively and are located in corresponding installation groove 8, and liner plate 4 front surfaces are higher than the front surface of the plate body 3 of locking a door.
Also be coated with the glue layer (not shown) on the contact-making surface of described liner plate 4 and installation groove 8, by before liner plate 4 is installed, smearing appropriate glue, can prevent that the contact-making surface of liner plate 4 from occurring rot and cause the bottom surface injustice, finally make liner plate 4 ftracture.And, when changing liner plate 4 next time, again smear after must clearing up glue.
Certainly, also can heat-treat liner plate 4, suitably to improve its hardness.
In addition, on the rear surface of the described plate body 3 of locking a door, built-up welding has a stainless steel antirust coat 9, can avoid its back that corrosion occurs, and guarantees its service life.
In sum, adopt the horizontal mill working roll of the present utility model plate of locking a door to there is following advantage:
1, lock a door plate body 3 is two independently parts with liner plate 4, and liner plate 4 is cheap, after the plate working face conquassation of locking a door, only need change liner plate 4 at machine and just can recover normally, and not need the integral replacing plate of locking a door, and higher economic worth is arranged;
2, liner plate 4 installation forms are simple, and weight is lighter, maintains easily;
3, suitably improve the material hardness of liner plate 4, greatly extended the service life of the plate of locking a door;
4, universal performance is good, conformability is high, and extreme high reliability is arranged, and is applicable to the similar milling train of the various plate structures of locking a door.
Those of ordinary skill in the art will be appreciated that, above specification is only one or more embodiments in the numerous embodiment of the utility model, and not uses restriction of the present utility model.Any variation of the equalization for the above embodiment, modification and be equal to the technical schemes such as alternative, as long as meet connotation scope of the present utility model, all will drop in the scope that claims of the present utility model protect.
