Description

Three sections collapsible entrance guide plates of milling train

Technical field

The utility model belongs to milling equipment, particularly three sections collapsible entrance guide plates of a kind of milling train.

Background technology

At present,, milling train is when rolled sheet metal, need to set up the entrance breast roll between roller-way and inlet of rolling mill, need set up entrance guide plate between breast roll and milling train, the version of this entrance guide plate is wanted to coordinate milling train to realize fast roll changing, and the inlet of rolling mill guide plate on existing conventional mill is to shift out milling train by level, namely realize the milling train fast roll changing away from milling train, therefore because milling train is set up the entrance breast roll, entrance guide plate can't move after level.Shortcoming and defect part for above-mentioned technology existence; Researching and developing a kind of new entrance guide plate that can satisfy the rolling requirement of sheet mill, is very necessary.

Summary of the invention

The utility model is intended to the shortcoming and defect that exists in above-mentioned technology; and provide a kind of syllogic collapsible entrance guide plate; the collapsible entrance guide plate of this syllogic is installed between entrance breast roll and operation roll of mill; its structure is not only reasonable in design; simple and practical; move after can making entrance guide plate, be convenient to again fast normal roll change, enhance productivity and operate the characteristics such as very convenient of using.

the purpose of this utility model is to adopt following technical scheme to realize: three sections collapsible entrance guide plates of described milling train, comprise entrance guide plate, operation roll of mill, it is characterized in that: installing entrance breast roll on the mill stand corresponding with the operation roll of mill position, the hydraulically powered three sections collapsible entrance guide plates of installing between described operation roll of mill and entrance breast roll, described hydraulically powered three sections collapsible entrance guide plates are by resting guide, the upset guide plate, folding guide plate and hydraulic cylinder form, its entrance breast roll inside top is sequentially installed resting guide, upset guide plate and folding guide plate, the extension bar top of the bottom of described upset guide plate and hydraulic cylinder is hinged, the bottom of this hydraulic cylinder is hinged on the mill stand free bearing, the outside and the resting guide of described upset guide plate are hinged, the folded inside guide plate of its upset guide plate is hinged, by when the work, pass through Driven by Hydraulic Cylinder, realize the entrance breast roll, the resting guide entrance guide plate, upset guide plate and folding guide plate form the integral planar for supplied materials.

Principle of the present utility model and characteristics are described below:

Installing entrance breast roll on mill stand in the utility model, hydraulically powered three sections collapsible entrance guide plates that installing is comprised of resting guide, upset guide plate, folding guide plate and hydraulic cylinder between its operation roll of mill and entrance breast roll.When milling train was in duty, the tiling of syllogic guide plate was opened, and was in supplied materials and imported state, and when milling train needed fast roll changing, the syllogic entrance guide plate was in folded state under the driving of hydraulic cylinder, was convenient to fast normal roll change, enhanced productivity.

The comprehensive above technical scheme of taking realizes the purpose of this utility model.

Compared with prior art, the utility model is not only reasonable in design, and is simple and practical, moves after can making entrance guide plate, is convenient to again fast normal roll change, enhances productivity and operates the characteristics such as very convenient of using.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

The utility model has three width accompanying drawings.Wherein:

Accompanying drawing 1 is the main TV structure schematic diagram of the duty of the utility model specific embodiment;

Accompanying drawing 2 is roll change view of the utility model specific embodiment.

Accompanying drawing 3 is entrance guide plate schematic diagrames of the conventional mill of prior art.

In figure: 1, resting guide, 2, the upset guide plate, 3, folding guide plate, 4, hydraulic cylinder, 5, the entrance breast roll, 6, operation roll of mill.

be specific embodiment of the utility model shown in Fig. 1,2, it is three sections collapsible entrance guide plates of milling train of installing on milling train, its structure comprises entrance guide plate, operation roll of mill, it is characterized in that: installing entrance breast roll 5 on the mill stand corresponding with operation roll of mill 5 positions, the hydraulically powered three sections collapsible entrance guide plates of installing between described operation roll of mill 6 and entrance breast roll 5, described hydraulically powered three sections collapsible entrance guide plates are by resting guide 1, upset guide plate 2, folding guide plate 3 and hydraulic cylinder 4 form, its entrance breast roll 5 inside top are sequentially installed resting guide 1, upset guide plate 2 and folding guide plate 3, the extension bar top of the bottom of described upset guide plate 2 and hydraulic cylinder 4 is hinged, the bottom of this hydraulic cylinder 4 is hinged on the mill stand free bearing, the outside of described upset guide plate 2 and resting guide 1 are hinged, the folded inside guide plate 3 of its upset guide plate 2 is hinged, by when the work, pass through Driven by Hydraulic Cylinder, realize the entrance breast roll, the resting guide entrance guide plate, upset guide plate and folding guide plate form the integral planar for supplied materials.

As can be seen from Figure 1, the collapsible guide plate of hydraulically powered syllogic that installing is comprised of resting guide 1, upset guide plate 2, folding guide plate 3 and hydraulic cylinder 4 between operation roll of mill 6 and sequence number entrance breast roll 5, its upset guide plate overturns around resting guide under the driving of the hydraulic cylinder 4 of separate unit, upset time upset guide plate also Foldable guide plate together moves, final motion arrival (as shown in Figure 2) roll change state position, this moment, folding guide plate and sequence number 6 operation roll of mill were thrown off fully, folding guide plate is folded together with the upset guide plate, guarantees that milling train changes working roll smoothly.

It is shown in Figure 3 is prior art entrance guide plate schematic diagram.Owing to there is no entrance breast roll 5, its entrance guide plate can not move horizontally.

The above; it is only the better specific embodiment of the present utility model; but protection domain of the present utility model is not limited to this; all are familiar with those skilled in the art in the disclosed technical scope of the utility model, according to the technical solution of the utility model and design of the present utility model thereof be equal to replace or change all should be encompassed in protection domain of the present utility model within.
