Abstract
Disclosed is a turnover device of a tandem mill for transporting for long distance relating to the turnover device in steel bar tandem rolling belonging to steel rolling technique field. The utility model is to resolve the lack of turnover device of a tandem mill for transporting for long distance during the product of steel bar tandem rolling. The utility model is of guiding groove structure, an inlet port of the guiding groove is of pipe socket shape, the outlet port of the guiding groove is of rectangular section shape, the middle portion of the guiding groove whose upper portion is wider than the lower portion is of ladder section shape, the ladder angle decreases gradually from an inlet port to an outlet port. With the utility model the steel material can be turned over gradually for 90 DEG, and the steel material enters into rolling mill arranged horizontally of next process. The utility model has the advantages of simple structure, convenient process and installation and easy regulation or the like, the utility model is applicable to transporting turnover device of entering into round or quadrate rolling hole of oblate steel material such as oval.
Description
Technical field
The utility model relates to the steel rolling production facility, and especially the lifting finger in the bar continuous rolling belongs to technical field of steel rolling.
Background technology
The many employings of pass schedule in the bar continuous rolling are ellipse---the circular hole system, and promptly the rolling groove of preceding a time milling train is oval, the rolling groove of back a time milling train is circular.When the roll of forward and backward milling train was arranged horizontally, oval rolled piece need overturn after 90 ° and to enter in the round pass of back a time milling train rolling with vertical state.Between the forward and backward horizontally disposed milling train during close together, can adopt the outlet torque tube to cooperate the inlet guide and guard to make ellipse roll 90 ° of material upsets, when distance between the forward and backward milling train is far away, if still adopt said apparatus, just the inaccurate situation of flip angle can appear because of fed distance is long, cause top steel (phenomenon of be obstructed in the conveying of steel material back jack-up or disengaging delivery track) thus, get rid of waste material, can cause security incident when serious because of the top steel causes to roll in a large number.Though above-mentioned long distance carries the frequency of occurrences of production technology lower, but can adopt aborning with demand because of various reasons, carry lifting finger so be necessary to develop the long distance that provides in the suitable bar continuous rolling.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of tandem rolling captain and uses lifting finger apart from carrying, to satisfy the production user demand of bar continuous rolling.
The alleged problem of the utility model realizes with following technical solution:
A kind of tandem rolling captain uses lifting finger apart from carrying, its unique distinction is, it is the gathering sill structure, the import position of gathering sill is that the biside plate of horn mouth shape, the port of export is vertical with horizontal direction, the middle part is trapezoidal sectional shape wide at the top and narrow at the bottom, and trapezoidal angle β is dwindled to Way out gradually by import.
For ease of processing, above-mentioned tandem rolling captain uses lifting finger, described gathering sill to be divided into 2～4 sections apart from carrying, the front and rear sections tandem array, and every section import is a bell mouth shape.
Above-mentioned tandem rolling captain uses lifting finger apart from carrying, and described gathering sill is by base plate 1, and side plate 2 is combined into, and the cross sectional shape of side plate 2 is " L " shape, and " L " shape side plate is installed on the base plate by bolt, and the bolt hole 1-1 on the base plate is a Long Circle.
Above-mentioned tandem rolling captain uses lifting finger apart from carrying, and the groove top of described gathering sill is provided with cover plate 3.
Above-mentioned tandem rolling captain uses lifting finger apart from carrying, the square-section width at described outlet position is greater than 3～8 millimeters of rolled piece thickness, the bottom width of described trapezoid cross section equates with the square-section width at outlet position, described trapezoidal angle β is contracted to 8 °～12 ° gradually by 20 °～30 °, and gathering sill groove depth H is 3～5 times of rolled piece height.
The gathering sill structure lifting finger that the utility model provides, rolled piece is overturn in course of conveying 90 ° gradually, enter down with required vertical state in the horizontally disposed milling train of a time, solved the steel problem of turning over of oval steel material in the long distance conveying, and have simple in structure, process easy for installationly, be easy to characteristics such as adjustment, the suitable long distance that enters circle or the rolling hole of square L as band steel material such as ellipses in the bar continuous rolling carries lifting finger to use.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the trapezoid cross section schematic diagram of gathering sill middle part;
Fig. 4 is a syndeton zoomed-in view between " L " shape side plate and the base plate.
The specific embodiment
Consult Fig. 1,2,3, the length at gathering sill import position is L among the figure, and the both sides at import position are outwards expanded, the bottom is expanded downwards, forms the horn mouth shape.Outlet position cross sectional shape is a rectangle, middle part cross sectional shape between the import and export is inverted trapezoidal, near the trapezoidal angle β of import is 25 °, trapezoidal angle β near outlet is contracted to 10 °, the bottom width of trapezoid cross section equates with the width of square-section, the square-section width both had been the groove width of gathering sill, and this width is greater than 4～6 millimeters of the thickness of oval rolled piece; The groove depth H of gathering sill is 3～5 times of oval rolled piece height.
Still consult Fig. 1,2, be convenient processing, gathering sill can be divided into 2～4 sections tandem arrays and form.Be divided into three sections in the illustrated embodiment, the side plate of every section import both sides expands outwardly the formation bell mouth shape.Every section guide groove working portion L among the figure
1, L
2, L
3Length is respectively 150-250mm, 200-300mm, 250-450mm, and the gathering sill total length is 1.6 meters.
Consult Fig. 1,2,3,4, the trough floor of gathering sill and the side plate of both sides can adopt the branch attachment structure, but base plate 1 double as installing plate, side plate 2 can be arranged in order by the section of cutting apart and be fixed on the base plate 1, the cross section of side plate 2 is " L " shape, be fixed on the base plate by bolt 4, adjust groove width during for ease of installation with suitable plurality of specifications product, adopt split can regulate syndeton between side plate and the base plate, promptly the bolt hole 1-1 on the base plate is a Long Circle shown in Figure 2, when unclamping bolt 4, the installation site of adjustable side plate, before making the side plate of the same side, back position correspondence forms continuous side plane, obtains required groove width simultaneously.
