Abstract

A wide rolling device for magnesium alloy plate, belongs to sheet metal rolling technical field, and the utility model solves existing magnesium alloy and rolls the technical problem that edges of boards split seriously, lumber recovery is low.Mainly comprise: be fixed on two laterally zygomorphic rolls in frame, one of them roll is symmetrical respectively at two ends is set with two sleeves, and the internal diameter of described sleeve is identical with the external diameter of roll, and is fixed on roll, rotates with roll; Described sleeve can adjust its position along roll axial direction on roll, and namely the width between described two sleeves is the target width rolling plate; Be positioned at rolling supplied materials side, be symmetrical arranged two guiders respectively rolling plate both sides, for the guiding of rolling plate.The utility model is used for the rolling of magnesium alloy, titanium alloy, molybdenum alloy, has and rolls the advantage that plate distortion is even, edge fault is few, lumber recovery is high.

Description

A kind of wide rolling device of magnesium alloy plate

Technical field

The utility model belongs to sheet metal rolling technical field, is specifically related to a kind of wide rolling device of magnesium alloy plate.

Background technology

Magnesium alloy has that density is little, specific strength and specific stiffness is high, electromagnetic wave shielding is good, damping shock absorption is good and be easy to the advantages such as machining, has broad application prospects in fields such as Aero-Space, automobile and electronic products.China is magnesium resource big country, and reserves and former magnesium export volume all occupy first place in the world, but has the magnesium alloy plate of high added value and the production technology comparatively backwardness of section bar, limits the range of application of magnesium alloy.

Wrought magnesium alloy sheet material is more and more extensive in the application in the fields such as the vehicles, electronics, automobile.Rolling is the major way that magnesium alloy plate is produced, but the crystal structure due to magnesium alloy is close-packed hexagonal, slip system is less, under room temperature, plastic deformation ability is poor, in the operation of rolling, processed finished products rate is lower, easily produce limit in process of production to split, cause magnesium alloy plate on the high side, thus limit the expansion application of magnesium alloy plate.

In the operation of rolling, magnesium alloy plate generation limit is split, and usually adopts the way reducing reduction in pass, multi-pass rolling, this reduces rolling efficiency.And in the operation of rolling, sheet material temperature declines very soon, also need to melt down heating to sheet material between passage, while reducing working (machining) efficiency, it is thick that material structure becomes, and also reduces plate property.Also have a kind of way split on limit of alleviating to be between rolling pass, arrange side roll, but problem is split on the very difficult sheet material limit that fundamentally solves.

Summary of the invention

The purpose of this utility model is the shortcoming overcoming prior art, provides a kind of wide rolling device of magnesium alloy plate, solves in prior art and rolls the technical problem that edges of boards split seriously, lumber recovery is low.

The utility model is achieved through the following technical solutions:

A kind of wide rolling device of magnesium alloy plate, comprise: be fixed on two laterally zygomorphic rolls in frame, it is characterized in that: in two described rolls, one of them roll is symmetrical respectively at two ends is set with two sleeves, the internal diameter of described sleeve is identical with the external diameter of roll, and be fixed on roll, rotate with roll; Described sleeve can adjust its position along roll axial direction on roll, and namely the width between described two sleeves is the target width rolling plate; Be positioned at rolling supplied materials side, be symmetrical arranged two guiders respectively rolling plate both sides, for the guiding of rolling plate.

The utility model compared with prior art, has the following advantages and beneficial effect:

The utility model have employed roll sleeve and rolls plate guider, achieve the wide rolling of the difficult deformable metals such as magnesium alloy, have and roll the advantage that plate distortion is even, edge fault is few, lumber recovery is high, solve prior art and roll the technical problem that edges of boards split seriously, lumber recovery is low, be particularly suitable for the Rolling Production of the difficult deformable metals such as magnesium alloy, titanium alloy, molybdenum alloy.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model (stereogram).

Detailed description of the invention

Embody the exemplary embodiments of the utility model feature & benefits, will describe in detail in the following description by reference to the accompanying drawings.Be understood that the utility model can have various changes in different embodiments, it neither departs from protection domain of the present utility model, and explanation wherein and to be shown in be use when explain in essence, and be not used to limit the utility model.

As shown in Figure 1, a kind of wide rolling device of magnesium alloy plate, comprise: be fixed on two laterally zygomorphic rolls in frame, in two described rolls, one of them roll 1 is symmetrical respectively at two ends is set with two sleeves 2, the internal diameter of described sleeve 2 is identical with the external diameter of roll 1, and is fixed on roll 1, rotates with roll 1; Described sleeve 2 can adjust its position along roll 1 axial direction on roll 1, and namely the width between described two sleeves 2 is the target width rolling plate 3; Be positioned at rolling supplied materials side, be symmetrical arranged two guiders 4 respectively rolling plate 3 both sides, for the guiding of rolling plate 3.

The utility model specifically can be implemented in a variety of forms and not depart from spirit of the present utility model or essence, so be to be understood that, above-described embodiment is not limited to aforesaid details, and should explain widely in claim limited range, therefore fall into change in claim or its equivalent scope and remodeling and all should be claim and contained.
