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.

为了提高精密五金加工中工件的质量，我们必须首先了解：精密加工的误差以及在精密加工中容易引起工件变形的主要因素。同时，我们还必须了解提高精密加工精度的三个原则。

1.提高切割水平

在精密加工中，切割工件时，工件表面会形成与工具形状几乎相同的压痕，并留下大量的鳞屑，这很容易增加工件表面的粗糙度并降低工件的表面质量；一般来说，在这种情况下，在切削过程中应适当增加刀具的顶弧半径，并适当减小刀具的进给量，以尽可能减小刀具在工件上的剩余区域的高度，确保将工件的表面粗糙度控制在适当的范围内，这样可以有效减少工件表面的堆积边缘和结垢，从而提高工件表面的质量并延长工件的使用寿命。

2.提高切割速度

当切削工件时，如果切削速度高，则切削过程中工件表面的塑性变形可以大大减少。切削速度越高，塑性变形程度越小，可以有效降低工件的表面粗糙度。如果切削速度不够快，则在切削过程中工件会积聚边缘，这会影响工件的表面质量。

3.提高精密加工设备的精度

工件的精密加工主要由机床完成。机床的误差将直接影响工件的精度。这就要求机床本身具有高精度，以有效减少加工过程中产生的误差。工具和夹具的误差也会影响工件的精度，可以采取相应的措施来减少工具的磨损。这样可以提高加工工件的精度和质量。

精密五金加工中工件的质量是企业发展的关键。因此，对于每个精密加工工厂来说，提高精密加工工件的质量和提高工件的质量都是当务之急。
