Abstract

The utility model relates to a rolling equipment field, concretely relates to transition backplate before flying shear, its technical scheme is for including welt and base: the lining plate is of a T-shaped upper and lower structure, two ends of the upper plate surface of the lining plate are sharp corners inclined by 60 degrees, and grooves are symmetrically arranged on two sides of the lower end of the lining plate; the base consists of a supporting side plate and a bottom plate and is fixed together by welding; the supporting side plate is inserted into the groove of the lining plate and is fixed by welding; the number of the lining plates is one or three, and when one lining plate is used, the width of the lining plate is the same as that of the supporting side plate; when the number of the lining plates is three, the lining plates are respectively welded at the front end, the rear end and the middle position of the supporting side plate. The utility model increases the welding strength and improves the impact resistance; when the number of the lining plates is three, spare part cost is saved, and the lining plates are repaired after damage.

Description

Transition backplate before flying shear

Technical Field

The utility model relates to a rolling equipment field, concretely relates to transition backplate before flying shear.

Background

The transition guard plate before flying shear is the last transition guard plate before strip steel enters the flying shear, and the working temperature is over 1000 ℃. When a rolling mill rolls a thick steel plate, the steel plate is seriously buckled, and the width of the guard plate is smaller relative to the guard plates at other positions, so that the guard plate is greatly impacted, the original design of the guard plate is that an upper plane lining plate is welded with a lower base, and the whole plate on the upper surface can only be externally welded, so that the impact resistance is weak, the lining plate is frequently welded, the influence on the stability of rolled steel is large, and steel clamping and equipment damage can be caused in serious cases.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides a transition backplate before flying shear.

The technical scheme of the utility model as follows:

the utility model provides a transition backplate before flying shear, includes welt and base:

the lining plate is of a T-shaped upper and lower structure, two ends of the upper plate surface of the lining plate are sharp corners inclined by 60 degrees, and grooves are symmetrically arranged on two sides of the lower end of the lining plate; the base consists of a supporting side plate and a bottom plate and is fixed together by welding; the supporting side plate is inserted into the groove of the lining plate and is fixed by welding;

the transition backplate before foretell flying shear, its preferred scheme does, welt lower extreme recess quantity is 2, and support curb plate quantity is 2.

According to the preferable scheme of the transition guard plate before the flying shear, the number of the lining plates is one or three, and when one lining plate is used, the width of the lining plate is the same as that of the supporting side plate; when the number of the lining plates is three, the lining plates are respectively welded at the front end, the rear end and the middle position of the supporting side plate.

The utility model has the advantages that:

(1) the welding strength is increased, and the impact resistance is improved;

(2) when the number of the lining plates is three, spare part cost is saved, and the lining plates are repaired after damage.

Detailed Description

Example 1:

as shown in figures 1-2, a transition backplate before flying shear includes welt 1 and base 2:

the lining plate 1 is of a T-shaped upper and lower structure, two ends 3 of the upper plate surface of the lining plate are sharp corners inclined by 60 degrees, and grooves 4 are symmetrically arranged on two sides of the lower end of the lining plate 1; the base 2 consists of a supporting side plate 5 and a bottom plate 6 which are fixed together by welding; the supporting side plate 5 is inserted into the groove 4 of the lining plate 1 and fixed by welding; the quantity of the grooves 4 at the lower end of the lining plate 1 is 2, and the quantity of the supporting side plates 5 is 2.

As shown in figure 3, when the number of the lining plates 1 is three, the lining plates 1 are respectively welded at the front end, the rear end and the middle position of the supporting side plate.

Example 2:

In the transition guard plate before flying shear, when the number of the lining plates 1 is one, the width of the lining plates 1 is the same as that of the supporting side plates 5.
