Choose 3mm aluminum sheet alloy grades, generally 1 series, 3 series, and 5 series are more commonly used, such as 3003 aluminum sheet. After deep processing of 3mm aluminum sheet, its application fields can be broadened. However, there are some things to pay attention to about the deep processing of 3mm aluminum sheet. Share with you.
When it comes to aluminum, everyone is familiar with the definition of aluminum. You can find its definition on many websites. The definition of aluminum sheet includes clear requirements for thickness, width, length and shape, which are between 0.2mm and 500mm in thickness, 200mm in width and 16m in length. The material shape is rectangular. In addition, the definition indicates that aluminum materials with a thickness of 0.2 mm or less usually exist in the form of aluminum foil. One form is aluminum strips, and their width is often less than 200 mm. With the advancement of technology, the width of today's aluminum strip can be increased to 600mm. There are some things to pay attention to about the deep processing of 3mm aluminium sheet. Share with you.
If you choose the alloy 3mm aluminium sheet, due to the high hardness of alloy aluminum, it is easy to break when bending, so you need to pay more attention when bending. In particular, a good raw material aluminum must be selected. In addition, pay attention to aluminum grades and temper. If there are project drawings, you can choose aluminum grades completely according to the drawing requirements. Generally, the 1 series, 3 series, and 5 series are more commonly used.
This problem should be analyzed according to specific customer requirements. Some customers require that a protective film be attached to the material on one side (smooth side) or on both sides. The protective film exists to avoid damage to the surface during transportation or processing. There is also a way to protect the product. During the processing, the parts are strictly required to be placed neatly in the designated position, and handled with care.
The surface of the part is punched. For the blanking and punching of parts, the gap between the upper and lower molds of the tool should be adjusted before the cutting and punching. Compared with the cutting of ordinary cold-rolled sheets, the gap should be reduced accordingly, so as to avoid excessive burrs in the punching cut.
Under the conditions of product use, try to increase the inner angle of the bending to reduce damage to the internal structure of the plate. The bending direction should be perpendicular to the grain direction of the aluminum sheet, not parallel. If one side fold is unavoidable, you can choose the short side fold to be parallel to the aluminum sheet material texture.
When welding, it depends on the thickness of the plate. In the selection of materials, the welding wire and welding type with corresponding performance should be selected. Adjust the corresponding voltage range, current range, and air pressure range.
