不锈钢钣金加工时采用的工艺主要有剪、冲、折弯、成型等多种冷加工工艺方法;而钣金厂也是通过这些工艺来将钣金材料制作成具有某种功能的零件。钣金通常是指将既定厚度的金属薄板，经过剪、冲、折弯、成型等多种冷加工工艺方法，来使其制作成具有某种功用的零件。经过这些冷加工方法，可以使钣金零件的厚度变化较为安稳。常见的钣金材料有多种，可是不同的钣金材料适合的用途和加工方式是有差别的。下面为您介绍不同的不锈钢钣金件加工材料所使用的加工工艺。
1.镀锌板。镀锌板是将钢板外表面进行镀锌的一种钢板，它的锌层厚度适中，且具有避免工件外表面遭到侵蚀等的作用。因而，它常被用于需要轻度防腐的结构件中。
2.铜板材。铜板材主要包括黄、紫、皱铜三种原料，铜原料主要被用于需要导电的料件中，其加工方法主要是在其表面进行镀镍、
镀铬处理，也可进行喷涂处理，但选用这种原料本钱较高。
3.热轧钢板。热轧钢板是以铸板坯或许初轧板为根底，经加热炉加热后，再经除磷后进行粗轧成形的钢板。热轧钢板的厚度等尺度精度稍逊，有时会出现折边等现象。因而，其主要用于桥梁、车辆、船只等结构件的生产。
4.铝板材。铝板材的表面通常要使用铬酸盐进行处理或许进行导电、化学等氧化处理，常被用于各式机箱体的制造。
5.冷轧钢板。冷轧钢板属不锈钢钣金材料的一种，它是在将室温控制到低于再结晶温度时，对钢板进行的进一步轧薄的钢板。冷轧钢板的表面滑润、厚薄匀称且精准、本钱较低、较易成型、且易于电镀和油漆，因而在各大制造业中均有应用。
钣金加工常见的几种表面处理方式为:拉丝、喷砂、烤漆、喷粉、电镀、阳极氧化、丝印。 由于某些钣金材料表面不具备防锈防腐蚀的能力，所以进行有效的表面处理是十分必要的。对钣金件进行表面处理可以提高产品在恶劣环境下的使用寿命，或者为了达到特定的表面效果或功能
1.拉丝
所谓钣金拉丝就是将材料放在拉丝机的上下绲轮之间,绲轮上附着有砂带,通过电机带动,让材料通过上下砂带,在材料表面拉出一道道痕迹,根据砂带的不同,痕迹粗细也不相同,主要作用是美化外观。另外拉丝也叫擦纹
2.喷砂
通过喷砂机的风力将砂粒打到工件表面上,在工件表面形成一层密布的凹坑，主要作用是去除工件表面的脏污、锈蚀，增加工件表面的附着力,为后续表面处理方式做准备。
3.喷漆
一般是指液体喷涂，他的工艺有两种:液体烤漆和自干喷漆，自干就是喷完了在常温下可以自然固化，成本较低，但效果跟烤漆没法比。喷漆的颜色效果会好一些，漆膜厚度比较薄，适合一些精密的产品，成本要高一些。
4.喷塑(也叫喷粉)
是指粉末被极化，在电场力的作用下，均匀附着在极性相反的产品表面。喷塑特点:耐磨，耐腐蚀方面比较好，膜比较厚，适合机柜、设备类的比较粗的产品，成本较低，塑粉还可以回收。

不锈钢钣金加工工艺和表面处理
Stainless steel sheet metal processing process used in the main shear, punching, bending, forming and other cold processing methods;And the sheet metal factory is also through these processes to make sheet metal materials into parts with a certain function.Sheet metal usually refers to the fixed thickness of the metal sheet, through shear, punching, bending, forming and other cold processing methods, so that it can be produced into parts with a certain function.Through these cold working methods, the thickness of sheet metal parts can be changed more stable.There are many common sheet metal materials, but different sheet metal materials suitable for use and processing methods are different.The following for you to introduce different stainless steel sheet metal parts processing materials used in the processing process.
1. Galvanized sheet.Galvanized sheet is a kind of steel plate that is galvanized on the outer surface of the steel plate. Its zinc layer thickness is moderate, and it has the effect of avoiding the erosion of the outer surface of the workpiece.Therefore, it is often used in structural parts that require mild corrosion resistance.
2. Copper sheet.Copper plate mainly includes yellow, purple, wrinkled copper three raw materials, copper raw materials are mainly used in the need for conductive materials, its processing method is mainly on the surface of nickel plating, chromium plating treatment, can also be sprayed treatment, but the choice of this raw material cost is higher.
3. Hot rolled steel plate.Hot rolled steel plate is a kind of steel plate which is formed by casting slab or initial rolled plate after heating in heating furnace and then roughing rolling after dephosphorization.The thickness and other scale accuracy of hot rolled steel plate is less, and sometimes the phenomenon of flanging will appear.Therefore, it is mainly used in the production of structural parts such as Bridges, vehicles and ships.
4. Aluminum sheet.The surface of aluminum plate is usually treated with chromate or conductive, chemical and other oxidation treatment, which is often used in the manufacture of various machine boxes.
5. Cold-rolled steel plates.Cold-rolled steel plate is a kind of stainless steel sheet metal material. It is further rolled steel plate when the room temperature is controlled below the recrystallization temperature.The surface of cold-rolled steel plate is smooth, the thickness is balanced and accurate, the cost is low, it is easy to form, and it is easy to electroplate and paint, so it has been used in various manufacturing industries.
Several common surface treatment methods of sheet metal processing are: wire drawing, sand blasting, paint baking, powder spraying, electroplating, anodic oxidation, screen printing.Because the surface of some sheet metal materials does not have the ability of rust and corrosion prevention, it is very necessary to carry out effective surface treatment.Surface treatment of sheet metal parts can improve the service life of the product in harsh environments, or to achieve a specific surface effect or function
1. The drawing
The so-called sheet metal wire drawing is to put the material in the wire drawing machine between the top and the bottom of the wheel, the sand belt attached to the wheel, driven by the motor, let the material through the upper and lower sand belt, pull out a trace on the surface of the material, according to the different sand belt, trace thickness is not the same, the main role is to beautify the appearance.In addition, drawing is also called wipe grain
2. Sandblasting
Through the wind blasting machine sand particles hit the surface of the workpiece, forming a layer of dense pits on the surface of the workpiece, the main role is to remove the dirt and rust on the surface of the workpiece, increase the adhesion of the surface of the workpiece, prepare for the subsequent surface treatment.
3. The spray paint
Generally refers to liquid spraying, there are two kinds of his process: liquid baking paint and self-drying spray, self-drying is sprayed out at room temperature can be naturally cured, the cost is lower, but the effect can not be compared with the paint.The color effect of spray paint will be better, the film thickness is relatively thin, suitable for some precision products, the cost is higher.
Step
4 Spray plastic (also known as powder)
It means that the powder is polarized, under the action of electric field force, uniformly attached to the surface of the product with opposite polarity.Spray characteristics: wear resistance, corrosion resistance is better, the film is thicker, suitable for cabinets, equipment class of relatively coarse products, low cost, plastic powder can also be recycled.
