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.

随着科学技术的发展和时代的变化，金属制品加工冲压行业逐渐渗透到人们的生活中。冲压件在生活中随处可见，从日用品到航空航天等大件，都需要金属冲压件。可见金属制品加工冲压件的质量也很重要。金属制品加工冲压技术有什么优势？

一、金属制品加工冲压的技术优势

1.金属冲压件是在数据消耗低的前提下，通过冲压来制造的。这些零件重量轻，刚性好。板料塑性变形后，金属内部的排列结构得到改善，从而使冲压件变得坚固。

2.金属冲压件尺寸精度高，尺寸与模块统一通用，互换性好。无需进一步加工即可满足一般器件和应用要求。

3.在冲压过程中，由于材料外观不受损，具有良好的外观质量和润滑性，为表面喷涂、电镀、磷化等表面处理提供了便利条件。

二、金属制品加工冲压材料的选择

冲压工艺主要有三种：冲压、弯曲和拉伸。不同的工艺对板材有不同的要求，板材的选择要根据产品的一般形状和加工工艺来考虑。

三、金属制品加工冲压用油品的选择

冲压油在冲压过程中起着关键作用。良好的冷却性能和极压抗磨性能使模具的使用寿命和工件精度的提高有了质的飞跃。根据工件材料的不同，选择冲压油时的性能侧重点也不同。

1.硅钢片是比较容易冲压的材料。一般为了清洗工件，会在防止冲孔毛刺的前提下选用低粘度的冲压油。

2.选择冲压油时，应根据工艺难度、拉丝油方法和脱脂情况，确定较好的碳钢板粘度。

3.镀锌钢板会与氯基添加剂发生反应，所以在选择镀锌钢板的冲压油时，要注意氯基冲压油可能出现的白锈问题。
