Precautions for deep processing of aluminum sheets Mingtai Aluminum

Edit:admin001 Date: 2019-05-26 15:27
Aluminum plate refers to an aluminum material with a thickness of 0.2mm or more and 500mm or less, a width of 200mm or more, and a length of 16m or less. It is called aluminum plate or aluminum sheet, aluminum material of 0.2mm or less, and material or strip of 200mm width. With the advancement of large equipment, the maximum width of 600mm can be achieved. The following matters to be noted in the deep processing of aluminum plates are as follows:
1. Plate selection: Due to the high hardness of the alloy aluminum plate, the bending is easy to break, so the raw materials must choose good aluminum, mainly look at the aluminum grade and state; select the aluminum grade according to the drawing requirements, generally 1 series, 3 series, 5 series More commonly used.
2, the protection of transportation and processing: according to the customer's requirements, the raw material is single-sided (glossy) or double-sided protective film to avoid damage to the surface of the parts during transportation or processing. At the same time, the parts are strictly required to be placed in the specified position during the processing. Take it lightly.
3. Punching of the surface of the part: the cutting and punching of the part, the gap between the upper and lower molds of the tool should be adjusted before the material is opened and punched. The gap between the upper and lower molds of the ordinary cold-rolled plate should be reduced accordingly, so that the punch can be avoided. The incision burr is too large.
4. Bending: Under the conditions of product use, try to increase the inner angle of the bend to reduce the internal knowledge of the damaged sheet; the direction of the bend should be perpendicular to the direction of the aluminum sheet, and it should not be parallel. If one side is not folded, you can choose short. The edge folds are parallel to the sheet grain.
5, welding: According to the thickness of the plate, the material properties select the corresponding wire and welding type, adjust the corresponding voltage range, current range, pressure range.
