详解挑选钣金加工匹配原材料的必要知识

现在钣金的加工发展相对快速,其中原材料对于该设备来说是至关重要的,因此对原材料会有比较严格的要求,因为原材料的缺陷会直接影响冲压件的优劣,所以对于原材料的选择要仔细。我们对一些原材料进行了解就会增加我们对钣金加工质量的提高。

Now the process of sheet metal processing is relatively rapid, the raw material is very important for the equipment, so the raw material will have more stringent requirements, because the defects of the raw materials will directly affect the quality of the stamping parts, so the selection of raw materials should be careful. Our understanding of some raw materials will increase our quality of sheet metal processing.

钣金加工原材料的重要性

钣金加工是指包括冲裁加工、切割下料、弯压成形等工艺的总称。钣金加工也就是对金属板材的加工,钣金加工中常见的原材料是钢材、铝材、铁等金属材料。

The importance of raw material for sheet metal processing

Sheet metal processing refers to the general process of punching, cutting and bending. Sheet metal processing is also the processing of sheet metal. The common raw materials in sheet metal processing are steel, aluminum, iron and other metal materials.

原材料的变形缺陷主要在钢材轧制和储运、吊装等过程中工艺不合理或违章操作造成的。例如钢板材料有较严重的不平变形缺陷,在利用龙门剪加工时,变形的钢板无法在剪床工作台上输进剪床剪刀的部位,剪切动作无法实现t给加工造成极大困难。由于产生不平、弯曲、扭曲等局部变形缺陷,直接影响放样、号料和下料的精度和质量,特别是下料工序。
The deformation defects of raw materials are mainly caused by unreasonable process or illegal operation in the process of steel rolling, storage and transportation, hoisting and so on. For example, the steel plate material has more serious uneven deformation defects. In the use of Longmen shearing, the deformation steel plate can not lose the scissors scissors on the scissors worktable. The shearing action can not make the T process a great difficulty.  Due to local deformation defects such as uneven, bending and twisting, it directly affects the accuracy and quality of lofting, marking and blanking, especially the blanking process.

除钢材的外形变形缺陷会影响放样、号料精度和质量,并影响下料的工艺加工难度外,还会因材料内应力大,在下料后内应力会进一步释放,造成变形进一步扩大.变形缺陷产生的危害也相应更大。又例如,钢板原材料在轧制过程中因工艺或设备存在问题,造成钢板产生应力和变形,在气割下料时由于工序加热和原来应力进一步释放,下料后往往会产生更大的应力变形,给以后加工成形或组焊工序造成极大的困难和影响。
In addition to the shape and deformation of steel, the precision and quality of the material will be affected, and the processing difficulty of the material will be affected. The stress in the material will be larger and the stress will be released further after the material, and the deformation will be further expanded. The damage caused by the deformation is also greater. For example, there are problems in the process or equipment during the rolling process of the raw material of steel plate, which causes the stress and deformation of the steel plate. In the process of gas cutting, the process heating and the original stress are further released. The stress and deformation of the raw material will often produce greater stress and deformation, which causes great difficulty and influence to the process forming or the group welding procedure in the future. . 

自动化和数字控制下料机械不但提高生产效率,保证产品质量,而且替代了展开放样和划线工序的工作。例如:数控剪板机、数控冲剪机等功能更健全合理;数控氧一乙炔切割机,激光切割机等的广泛应用已大量取代手工切割技术,取得提高生产效益、保证产品质量的效果。机械下料设备已应用高精尖的技术,例如高压水切割技术(切割水束的压力≥400MPa),可切割厚度100mm以上的钢板和大型棒料。

Automation and digital control cutting machines not only improve production efficiency, ensure product quality, but also replace the work of lofting and scribing. For example: CNC shearing machine, CNC punching machine and other functions are more sound and reasonable; CNC oxyacetylene cutting machine, laser cutting machine and other wide applications have replaced manual cutting technology, to improve the efficiency of production and guarantee the quality of the product. The mechanical laying equipment has applied high and sophisticated technology, such as high pressure water cutting technology (the pressure of cutting water beam is more than 400MPa), and can cut steel plate and large rod with a thickness of more than 100mm.
