Abstract
The invention discloses a magnesium alloy plate rolling device, which comprises a roller pair consisting of an upper roller and a lower roller, and a front tension roller and a rear tension roller distributed at two sides of the roller pair; through the front tension roller, the tension part of a plate higher than or lower than a roller gap between the upper roller and the lower roller forms a structure that the plate is obliquely nipped into the roller gap; and because the plate blank is obliquely nipped into the roller gap, the rolling time of the upper and lower rollers is different, the grain orientation of the rolled magnesium alloy plate is oblique, the forming performance of the plate is improved, and the defects of cracks produced at the bent position during forming and the like are avoided.
Description
Technical field
The present invention relates to a kind of rolling equipment, particularly a kind of magnesium alloy rolling equipment.
Background technology
Magnesium alloy is the lightest metal material in the present commercial Application; It has light weight, intensity height, good rigidly, good processability, dimensional stability height, shock resistance, wear-resisting, fade performance good and be easy to advantages such as recovery; Can substituted for plastic, material such as steel; Satisfy the requirement such as light, thin and integrated of product, in a lot of fields application in recent years increases rapidly.
Because the fusing point of magnesium alloy is lower, normal temperature compacted under poor-performing, die casting performance is good, thereby the processing of magnesium alloy to be being die cast as the master, but the mechanical property of magnesium alloy die casting is undesirable, and surface quality is relatively poor, and can't produce big and thin part.Be the better utilization magnesium alloy, improve its comprehensive mechanical property, need research to use to forge, rolling, extrude etc. it carried out the technology of secondary operations.Existing rolling equipment generally be by roll to be distributed in roll the preceding idler roller of both sides and back idler roller constituted; Preceding idler roller, roll gap and back idler roller along continuous straight runs linearly distribute; Using the grain orientation of the magnesium alloy plate that this equipment produces is the vertical direction along the plate face, causes the punching performance of magnesium alloy plate lower, only limits to the less distortion of bending radius; If deflection is bigger, will cause the knee defectives such as crackle to occur.
To above-mentioned deficiency, need to explore a kind of device that is used for magnesium alloy rolling, make it can produce the magnesium alloy plate that grain orientation helps improving punching performance.
Summary of the invention
In view of this; The present invention provides a kind of magnesium alloy plate rolling device; Through preceding idler roller is departed from the horizontal direction certain distance, magnesium alloy plate is tilted nip roll, cause its when rolling deformation up and down pressurized produce a time difference; Thereby make its grain orientation for favouring the plate face, reach the purpose of the punching performance that improves magnesium alloy plate.
Magnesium alloy plate rolling device of the present invention; Comprise the roll that constitutes by top roll and lower roll to, be distributed in forward pull roller and the backward pull roller of roll to both sides, said forward pull roller is higher or lower than roll gap between top roll and the lower roll to the tensioning position of sheet material and forms sheet material tilt the to nip structure of roll gap.
Further, the tensioning position of the tensioning position of said forward pull roller, roll gap and backward pull roller linearly distributes;
Further, nip direction and the angle between the horizontal direction of roll gap of said sheet material is 5～15 degree.
The beneficial effect of the invention: magnesium alloy plate rolling device of the present invention; Comprise the roll that constitutes by top roll and lower roll to, be distributed in forward pull roller and the backward pull roller of roll to both sides; Said forward pull roller is higher or lower than roll gap between top roll and the lower roll to the tensioning position of sheet material and forms sheet material tilt the to nip structure of roll gap; The slab roll gap that tilts to nip makes up-down rollers produce on the rolling time slab and has a time difference, and the grain orientation of the magnesium alloy plate that rolls out is tilted; Help improving the processability of sheet material, defectives such as crackle appear in the knee when avoiding moulding.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the structural representation of rolling device in the prior art.
The specific embodiment
Below will combine accompanying drawing that the present invention is described in detail; As shown in the figure: the magnesium alloy plate rolling device of present embodiment; Comprise the roll that constitutes by top roll 1 and lower roll 2 to, be distributed in forward pull roller 3 and the backward pull roller 4 of roll to both sides, the tensioning position of 3 pairs of sheet materials of said forward pull roller is higher than roll gap 5 between top roll 1 and the lower roll 2 and forms sheet materials tilt the to nip structure of roll gap 5, the roll gap because the slab inclination is nipped; Up-down rollers is produced on the rolling time slab have a time difference; The grain orientation of the magnesium alloy plate that rolls out is tilted, help improving the processability of sheet material, defectives such as crackle appear in the knee when avoiding moulding.Certainly, the tensioning position of 3 pairs of sheet materials of forward pull roller is lower than the roll gap 5 between top roll 1 and the lower roll 2, as long as sheet material is tilted nip roll gap, all can realize the object of the invention.
Further improvement as technique scheme; The roll gap 5 between the tensioning position of said forward pull roller 3, top roll 1 and the lower roll 2 and the tensioning position of backward pull roller 4 linearly distribute; Reduce the bending of sheet material in rolling course of conveying, help reducing transporting resistance.
Further improvement as technique scheme; The nip direction of roll gap 5 and the angle a between the horizontal direction of said sheet material is 5～15 degree; The angle of nipping that choose reasonable is best; Also be unlikely to excessive when making the sheet material grain orientation be tilted in the processability of improving sheet material, roll out and both possess the magnesium alloy plate that good processability also possesses the favorable mechanical performance performance impacts such as timber intensities.
Explanation is at last; Above embodiment is only unrestricted in order to technical scheme of the present invention to be described; Although with reference to preferred embodiment the present invention is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement technical scheme of the present invention; And not breaking away from the aim and the scope of technical scheme of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
