Product Details

Sheet metal processing is mainly to complete the production of products by cutting, forming, correcting and assembling various metal materials. Therefore, you must have certain knowledge about the quantities, properties and uses of common metal materials in order to use these materials reasonably and master the correct sheet metal processing techniques.

Sheet metal processing and cutting

The cutting method is to use a disc shearing blade to cut the sheet in the opposite rolling direction. According to the disc equipment, it can be divided into linear equipment, oblique linear equipment and oblique equipment. Straight equipment is suitable for cutting sheet metal into strips or cutting square blanks into circular blanks in sheet metal processing. The oblique straight equipment is suitable for cutting circular blanks or circular inner holes, and the oblique equipment is suitable for cutting arbitrary curves. blank.

1. Straight equipment to cut paper. When using the straight line equipment to cut the plate, please align the straight line center line of the upper and lower hob first, the gap between the upper and lower cutting blades is usually 0.05-0.5mm, or adjust the upper and lower hob a little. Sheet metal processing The stacking conditions make the stacking height h generally only 0.2-0.3 times the thickness of the shear plate.

2. Sheet metal processing cutting board with tilting equipment. Beveling equipment is widely used for cutting curved boards. Before cutting the paper, the upper and lower reels are tilted devices, and the angle between the upper and lower reels is set to 25 degrees. Then adjust the speed and gap of the egg cutter according to the thickness of the slices.

3. The cutting dimensional accuracy of beveled sheet metal processing equipment. When a generalized disc rolling and shearing curve is chosen, the radius of curvature of the blank has a certain limit, and its small radius of curvature is related to the diameter of the cutting blade and the thickness of the half-body material, and when in the disc rolling For straight bars, the small width error is also limited.

铝板加工是钣金加工中常见的问题。问题之一是铝板能否用激光切割。答案是肯定的，可以激光切割。

几年前，激光切割机可以切割铝板。记得当时工人在铝板上涂墨水(据说铝板反射系数高，怕反射激光)。此外，激光参数难以调整。当时只能切割1mm厚的铝板。积累经验后，铝板切割非常顺利，没有夹渣。

激光切割机切割铝板还取决于激光发生器的功率。厚度6000W可切16mm，4500W可切12mm。但是加工成本很高，因为是高反射材料。激光切割是用高功率密度的聚焦激光束照射工件，使被照射的材料迅速熔化、汽化、烧蚀或达到燃点。同时，借助同轴激光束，高速气流将熔融材料吹走，从而实现对工件的切割。

激光切割铝板的切割面和其他材料一样光滑吗？

铝板的缺口也很光滑。铝板只是一种高反射材料，需要很大的激光发生器和切割气体。和其他材料一样，用氮气切割，不会造成表面不光滑。

以上是铝激光切割的一些个人经验。我们从专业层面收集其资料来解释一下。

铝板是用激光切割的

1.精切缝:激光切割铝板的切割缝一般为0.1-0.2毫米

2.切割面平整:激光切割铝板的切割面无毛刺和夹渣。

3.热变形小:激光加工的激光切割缝薄且快，能量集中，所以传递给被切割材料的热量小，材料的变形也小。

4.节省材料:激光加工采用计算机编程，激光设备可以为不同形状的铝板加工零件切割材料，提高了铝板的材料利用率，节省了大量的材料成本。

5.切割铝板的厚度取决于激光发生器的功率。一般来说，厚铝板在6000W可以切成16mm，在4500W可以切成16mm。
