Abstract

A four-high rolling mill guide device with a replaceable guide buckle hand belongs to the technical field of rolling mill equipment and aims to enable a guide buckle hand to be rapidly replaced and guide functions to be recovered if the guide buckle hand is damaged. The technical scheme is that a guide buckle hand and a guide framework of the device are separate structures; a groove along the length is disposed onto a contact surface between the guide buckle hand and the guide framework; the guide framework is equipped with a projection which is embedded into the groove of the guide buckle hand and is in tight cooperation with the groove; and the guide buckle hand and the guide framework are connected via multiple connecting bolts. The guide buckle hand and the guide framework can be separated, the groove and the projection are disposed between the guide buckle hand and the guide framework for tight cooperation and positioning, and firm connection is formed through multiple high-strength connecting bolts, such that only the guide buckle hand needs to be replaced once being damaged, and thus the time and cost of maintenance can be substantially reduced. The four-high rolling mill guide device is simple in structure and convenient for replacement of the guide buckle hand, helps to ensure normal guide work, and has substantial economic benefits.

Description

A kind of replaceable guide and guard attacker's four-high mill guide and guards

Technical field

The utility model relates to a kind of guide and guards of four-high mill, belongs to milling equipment technical field.

Background technology

In steel plate rolling is produced, four-high mill is mainly that steel billet is formed to rolling and broadening rolling.Guide and guards is the important component part of four-high mill, and its major function is for guiding stocking to enter roll gap.The cooling manifold etc. that guide and guards is mainly wiped roller device, top working roll and backing roll by descaling header, guide and guard attacker, upper working rolls and lower working rolls forms.Guide and guards is arranged on the column slideway of roll line top discrepancy memorial archway, by guide and guard lifting hydraulic cylinder, is suspended in top backing up roll balance sysmte, can move with top backing up roll, also can be by guide and guard lift cylinder and upper backup roll relative motion.Guide and guard attacker and guide and guard main frame are the structures of one, through using for a long time, guide and guard attacker place is by steel plate collision deformation or damage, can not combine with working roll backplate, after guide and guard attacker and working roll backplate produce and relatively move, there is stuck state in guide and guards, causes guide and guards normally not use, and affected the use function of milling train.Owing to leading attacker's damage, just need to change guide and guard, increase spare part expense and maintenance time, therefore be necessary existing equipment to improve.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of replaceable guide and guard attacker's four-high mill guide and guards, this guide and guards can carry out quick-replaceable guide and guard attacker to guide and guard attacker by steel plate collision deformation or while damaging, thereby guarantees the use function of guide and guards.

The technical scheme solving the problems of the technologies described above is:

A kind of replaceable guide and guard attacker's four-high mill guide and guards, it is by descaling header, guide and guard attacker, upper working rolls and lower working rolls is wiped roller device, the compositions such as cooling manifold of top working roll and backing roll, its improvements are, its guide and guard attacker and guiding frame are Split type structure, guide and guard attacker is arranged on the front end of guiding frame, fluted on the contact-making surface of guide and guard attacker and guiding frame, groove is along guide and guard attacker's length direction, on guiding frame and guide and guard attacker's contact-making surface, there is projection, the projection of guiding frame embeds in guide and guard attacker's groove, the projection of guiding frame and guide and guard attacker's groove closely cooperates, a plurality of connecting bolts are vertically connected guide and guard attacker through the projection of guiding frame and guide and guard attacker's groove along guide and guard attacker's length direction with guiding frame.

Above-mentioned replaceable guide and guard attacker's four-high mill guide and guards, described guide and guard attacker is equally divided into two sections in the longitudinal direction, and two sections are fixedly connected with by connecting bolt with guiding frame respectively, and connecting bolt is interior six square bolts.

The beneficial effects of the utility model are:

The utility model changes guide and guard attacker and the guiding frame of guide and guards as Split type structure into by integrative-structure, fluted and the projection location that closely cooperates between guide and guard attacker and guiding frame, adopt a plurality of high strength connecting bolts to connect, realizing guide and guard attacker is connected with the firm of guiding frame, after guide and guard attacker is damaged, only need to change guide and guard attacker, need not change and keep in repair guide and guard, greatly save repair time and expense.The utility model is simple in structure, making is easy, replacing is convenient, can guarantee that guide and guard normally work, and has significant economic benefit.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Number in the figure is as follows: guide and guard attacker 1, connecting bolt 2, guiding frame 3, groove 4, projection 5.

The specific embodiment

The utility model is comprised of guide and guard attacker 1, connecting bolt 2, guiding frame 3.

In figure, show, guide and guard attacker 1 is Split type structure with guiding frame 3, and guide and guard attacker 1 is arranged on the front end of guiding frame 3.On the contact-making surface of guide and guard attacker 1 and guiding frame 3 fluted 4, groove 4 is along guide and guard attacker 1 length direction, on guiding frame 3 and guide and guard attacker's 1 contact-making surface, there is projection 5, the projection 5 of guiding frame 3 embeds in guide and guard attacker 1 groove 4, the projection 5 of guiding frame 3 closely cooperates with guide and guard attacker 1 groove 4, and guide and guard attacker 1 is located by connecting with guiding frame 3.

In figure, show, guide and guard attacker 1 is connected by bolt with guiding frame 3, a plurality of connecting bolts 2 are along guide and guard attacker 1 the uniform arrangement of length direction, and connecting bolt 2 is vertical to be fastenedly connected guide and guard attacker 1 to be integrated with guiding frame 3 through the projection 5 of guiding frame 3 and guide and guard attacker 1 groove 4.

In figure, show, guide and guard attacker 1 is equally divided into two sections in the longitudinal direction, and two sections are fixedly connected with by connecting bolt 2 with guiding frame 3 respectively, and connecting bolt 2 is interior six square bolts.

The connecting bolt of an embodiment of the present utility model is interior six square bolts of M30 * 190, and quantity is 20, and is high-strength bolt, can meet requirement of strength.

After improving, if guide and guard attacker 1 position is damaged, just can carry out quick-replaceable to guide and guard attacker 1 parts, thereby guarantee the use function of guide and guard, can also greatly reduce repair time and spare part expense.
