Technical Field

The invention relates to a rolling method for a metal plate.

Background

In the prior art, when a metal plate (including a metal sheet and a metal foil) is rolled by using embossing rollers, the metal plate is generally rolled and formed at one time by a group of embossing rollers so as to obtain a product with the required thickness and pattern, and the product is relatively thin. To make thicker products, the sheet metal is generally rolled by increasing the depth of the pattern. The method easily causes the problems of cracking and the like of the metal plate in the rolling process, and seriously affects the product quality and the production efficiency.

Disclosure of Invention

The invention aims to provide a rolling method of a metal plate, which can roll the metal plate with the same thickness to prepare a thicker product through two rolling steps so as to meet different use requirements.

In order to achieve the purpose, the invention adopts the technical scheme that:

a sheet metal rolling method comprising the steps of:

(1) passing a metal plate through a first embossing roller set along a feeding direction, wherein the first embossing roller set is used for rolling the surface of the metal plate to form wrinkles;

(2) and enabling the metal plate with the wrinkles to pass through a second embossing roller set along the feeding direction, and rolling and forming the metal plate by the second embossing roller set to enable the formed metal plate to be thicker than the metal plate with the wrinkles.

Preferably, in the step (1), the first embossing roll set comprises at least one pair of first embossing rolls, and the metal plate material is sequentially passed through all the pairs of first embossing rolls.

More preferably, in the step (1), the thickness of the metal plate material in which wrinkles are generated is adjusted by adjusting the number of pairs of the first embossing rolls.

Preferably, in the step (2), the second embossing roller group includes at least one pair of second embossing rollers, and the metal plate material with wrinkles is sequentially passed through all the pairs of second embossing rollers.

More preferably, in the step (2), the thickness of the formed metal plate material is adjusted by adjusting the number of pairs of the second embossing rolls.

Preferably, the depth of a first pattern in the first pattern-roller group is smaller than the depth of a second pattern in the second pattern-roller group.

Preferably, in step (1), the first embossing roll set is used for rolling and preforming the metal sheet, and the corrugation of the metal sheet is a preformed pattern.

Due to the application of the technical scheme, compared with the prior art, the invention has the following advantages: according to the rolling method for the metal plate, disclosed by the invention, the metal plate with the same thickness can be rolled to prepare a thicker product through two rolling steps, so that not only is the strength of the product increased, but also the thickness and the application of the product are increased.

Detailed Description

The technical solution of the present invention is further illustrated by the following specific examples.

The rolling method of the metal sheet comprises the following steps:

(1) passing the metal plate through a first embossing roller set along the feeding direction, and rolling the first embossing roller set on the surface of the metal plate to form folds;

in the present application, the metal plate includes a metal skin and a metal foil; in the embodiment, an aluminum foil with the thickness of 30 filaments passes through a first pattern roller set along the feeding direction, and the aluminum foil with the thickness of 4mm and folds on the surface is prepared after rolling;

(2) enabling the metal plate with the wrinkles to pass through a second embossing roller set along the feeding direction, and rolling and forming the metal plate by the second embossing roller set;

in this example, a corrugated aluminum foil having a thickness of 4mm was passed through a second pattern roller group in the feeding direction, and rolled to obtain a molded product having a thickness of 10 mm.

According to the rolling method for the metal plate, disclosed by the invention, the metal plate with the same thickness can be rolled to prepare a thicker product through two rolling steps, so that the strength of the product is increased, and the thickness and the application of the product are increased, such as door plates, furniture and the like.

In the prior art, due to the metal tensile property and the internal stress, an aluminum foil with the thickness of 30 wires cannot be rolled to the thickness of 10mm by a patterned roller at one time, and the surface of the aluminum foil is only torn due to forced rolling. In this embodiment, the aluminum foil is rolled once to have a certain thickness and strength, and then rolled twice to have a desired thickness.

In the step (1), the first embossing roller set comprises at least one pair of first embossing rollers, and the metal plate is sequentially passed through all pairs of first embossing rollers. In this embodiment, the first embossing roll set includes only one pair of first embossing rolls through which the aluminum foil having a thickness of 30 filaments passes in the feeding direction. When the first embossing roll has a plurality of pairs, in the step (1), the thickness of the metal plate material with the wrinkles can be adjusted by adjusting the number of pairs of the first embossing roll. The greater the number of pairs of first embossing rollers, the thicker the sheet metal output.

In the step (2), the second embossing roller group comprises at least one pair of second embossing rollers, and the corrugated metal plate is sequentially passed through all the pairs of second embossing rollers. In this embodiment, the second embossing roller group comprises only one pair of second embossing rollers through which the wrinkled aluminum foil having a thickness of 4mm is passed in the feeding direction. When the second embossing roll has a plurality of pairs, the thickness of the formed metal plate can be adjusted by adjusting the number of pairs of the second embossing rolls in the step (2). The greater the number of pairs of second embossing rollers, the thicker the sheet metal formed.

The depth or the height of the protrusions of the first pattern in the first pattern-roller group is smaller than the depth or the height of the protrusions of the second pattern in the second pattern-roller group.

In step (1), the first embossing roll set can also be used for preforming the metal plate, and the wrinkles of the metal plate are the preformed patterns. The shape of the first pattern in the first pattern roller group is similar to or the same as that of the second pattern in the second pattern roller group, and the depth of the first pattern is smaller than that of the second pattern.

The above-mentioned embodiments are merely illustrative of the technical idea and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered in the scope of the present invention.
