Abstract
The utility model relates to a hole pattern of a vertical rolling mill in the rolling process in the field of metallurgy and discloses a vertical roll hole pattern for improving a natural round edge of ribbon steel for an automobile beam. Two internal chamfers at the bottom of a hole slot of the vertical roll hole pattern intersect so as to form an circular arc. The vertical roll hole pattern disclosed by the utility model is simple in structure; the two internal chamfers at the bottom of the hole slot intersect so as to form an circular arc, so that a rolled piece is rolled through the vertical roll hole pattern to obtain a natural round edge with full roundness, secondary processing is not needed, thereby improving the operating efficiency and reducing the production cost.
Description
Technical field
The utility model relates to the pass of vertical miller in the field of metallurgy operation of rolling, and a kind of vehicle beam that improves is with the vertical roll hole of ribbon steel nature round edge specifically.
Background technology
The vehicle beam ribbon steel is the material of replace imported, and the index that plays a key is exactly the natural round edge of steel band, and hot rolling out steel band will have the full round edge of circularity.In the prior art, the pass of vertical miller is that two interior chamferings of hole slot bottom are not arc transition in the operation of rolling, forms the angle, therefore hot rolling vehicle beam does not out have the full round edge of circularity with ribbon steel, need secondary operations, when operating efficiency reduces, increased production cost.
The utility model content
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, provide a kind of vehicle beam that improves with the vertical roll hole of ribbon steel nature round edge, but hot rolling goes out the steel band of the full round edge of circularity.
The technical scheme that the utility model solves above technical problem is:
A kind of vehicle beam that improves is with the vertical roll hole of ribbon steel nature round edge, and two interior chamferings of the hole slot bottom that vertical roll hole has intersect and form circular arc.
The technical scheme that the utility model further limits is:
The aforesaid vehicle beam that improves is with the vertical roll hole of ribbon steel nature round edge, and circular arc is semicircle.
The aforesaid vehicle beam that improves is with the vertical roll hole of ribbon steel nature round edge, and the hole slot bottom level is supplied materials thickness.
The beneficial effects of the utility model are: the utility model is simple in structure, the formation circular arc is intersected at two interior chamfering angles of hole slot bottom, so that rolled piece process vertical roll hole is rolling, can access the full natural round edge of circularity, need not secondary operations, when operating efficiency improves, reduced production cost.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The present embodiment provides a kind of vehicle beam that improves with the vertical roll hole of ribbon steel nature round edge, structure as shown in Figure 1, two interior chamferings 1 of hole slot that vertical roll hole has bottom and 2 intersect and form circular arcs 3, circular arc 3 is semicircle, and the utility model is determined supplied materials thickness according to front a time milling train outlet material type, determine edger roll hole slot bottom level according to supplied materials thickness, calculate the hole slot opening degree, two interior chamferings with the hole slot bottom intersect simultaneously, form semicircle again.Use the utility model, so that the automobile steel band of 6.15mm is through after rolling, it is semicircle that natural round edge becomes.
The utility model is simple in structure, two interior chamfering angles of hole slot bottom is intersected form circular arc, so that rolled piece process vertical roll hole is rolling, can access the full natural round edge of circularity, need not secondary operations, when operating efficiency improves, has reduced production cost.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
Claims (3)
1. one kind is improved vehicle beam with the vertical roll hole of ribbon steel nature round edge, it is characterized in that: the crossing circular arc that forms of two interior chamferings of the hole slot bottom that described vertical roll hole has.
2. the vehicle beam that improves as claimed in claim 1 is with the vertical roll hole of ribbon steel nature round edge, and it is characterized in that: described circular arc is semicircle.
3. the vehicle beam that improves as claimed in claim 1 or 2 is with the vertical roll hole of ribbon steel nature round edge, and it is characterized in that: described hole slot bottom level is supplied materials thickness.
