Abstract

The utility model relates to a guide plate. Compared with the traditional planar guide plate, the working face is wave shaped, which can ensure that not the whole working face of guide plate is contacted with the edge of band steel during production, and thus the contact area is reduced; on one hand, the influence of the guide plate to the edge quality of the band steel can be greatly reduced, on the other hand, the structural dimension of a lining plate can be greatly reduced, and thereby the cost of spare parts for the lining plate can be reduced. Simultaneously, the lining plate is inserted into a dovetail slot, without being fastened with bolts, therefore the installation is easy, the connection is firm, and maintenance can be completely avoided; the lining plate is inserted directly, the bolts are cancelled, and thereby a series of problems caused by the loosening of the bolts are eliminated.

Description

Foreplate

Technical field

The utility model relates to the steel rolling equipment technical field, relates in particular to a kind of foreplate.

Background technology

As shown in Figures 1 to 4, steel rolling mill's employed its working face of various foreplates at present all is a flat face, and on the straight working face liner plate is installed, and

liner plate

2,3,4,5 usefulness bolts 6, nut 7, pad 8 connections are fastened on the foreplate body 1.In the course of the work, whole straight working face all can contact with the strip edge portion in producing.Two rollgang 9 two ends that are installed in rolling line about foreplate divides, when the band steel arrives foreplate on rollgang 9, about two foreplates clamp the band steel simultaneously, foreplate to the band steel play guide effect, make the band steel enter milling train, flying shearing machine and coiling machine smoothly.When foreplate clamped the band steel, strip edge portion contacted and strong friction fully with the foreplate liner plate.

Thereby there is following wretched insufficiency at work in the foreplate of this straight structure:

1, the strip edge portion in the production all contacts with the whole straight working face of foreplate, and contact area is big, has increased the influence of foreplate to strip edge portion quality;

2, the whole straight working face of foreplate all is equipped with liner plate, and the lining plate structure size is big, unit price cost height, and it is big to change the scrap cost loss.

3, the physical dimension of four blocks of liner plates on the same foreplate can't be done equally, and four blocks of liner plates do not have general interchangeability, and every block of liner plate all must have independent spare part, causes Inventory of Spare Parts big;

4, liner plate is connected with this body and function of foreplate bolt, and bolt easily becomes flexible and causes faults such as liner plate becomes flexible, comes off, thereby maintenance workload is big in the use;

5, behind the wear liner, bolt head exposes the liner plate face and badly damaged strip edge portion quality.

The utility model content

The purpose of this utility model provides a kind of foreplate, by reducing the contact area of foreplate and strip edge portion, reduces the influence to strip edge portion quality, reduces the liner plate area simultaneously, reduces cost.

In order to solve the problems of the technologies described above, the inner side edge of foreplate body of the present utility model is set to waveform, has so just significantly reduced the contact with the strip area of part of foreplate.Simultaneously, the place is fixed with liner plate at crest, has also significantly reduced the area of liner plate, has saved cost, and the liner spare part consumption costs is reduced greatly.

As a kind of improvement of the present utility model, described liner plate is vertical plug-in mounting with the mode of fixedlying connected of foreplate.Bolt is easily loosening and cause faults such as liner plate becomes flexible, comes off in the time of can reducing the conventional bolt connected mode like this, thereby, reduce use in maintenance workload.After simultaneously can avoiding wear liner, bolt head exposes the liner plate face and badly damaged strip edge portion quality.

As another kind of improvement the of the present utility model, the plug-in mounting syndeton of described liner plate and foreplate is an oat tail groove structure.Do not need to use bolted, simple installation is connected firmly again, and is non-maintaining fully in the use.

The specific embodiment

See also accompanying drawing 5 to accompanying drawing 8, in the preferred embodiment of the present utility model, the working face of foreplate body 1 structure in wave shape, and its waveform is mild, lines are smoothly smooth, like this with respect to more sharp-pointed waveform, in the time of just can preventing to be with steel to arrive foreplate on rollgang 3, band steel and the collision of foreplate wavy surface, the rubstrip steel.The place has dovetail groove at foreplate working face crest; The thickness of the height of liner plate 2 and foreplate body 1 is suitable, liner plate 2 is made the dovetail structure, only liner plate 2 is installed on the waveform working face at the crest place, the physical dimension of liner plate is just the same, can generally exchange, liner plate all is directly to inject in the dovetail groove at waveform working face crest place of foreplate body 1, does not need to use bolted again.

When foreplate was worked, foreplate clamped the band steel, and strip edge portion only contacts with the liner plate at foreplate waveform working face crest place, and other working face does not contact with strip edge portion.

More than be a preferred embodiment of the present utility model, the connected mode of foreplate body and liner plate also can adopt alternate manner, clamps etc. as Embedded, also can easily realize the purpose of this utility model.

Claims

1. foreplate is characterized in that:

The inner side edge of foreplate body is in wave shape, and the place is fixed with liner plate at crest.

2. foreplate as claimed in claim 1 is characterized in that: described liner plate is vertical plug-in mounting with the mode of fixedlying connected of foreplate.

3. foreplate as claimed in claim 2 is characterized in that: the plug-in mounting syndeton of described liner plate and foreplate is an oat tail groove structure.
