由于钣金机箱的效果非常关键，钣金机箱的加工非常关键且严谨的。只有充分掌握所涉及的各个工序，遵守相关规定，才能更好地保证钣金机箱加工质量达到要求。那么钣金机箱加工会涉及哪些工序呢？

As the effect of sheet metal chassis is very critical, the processing of sheet metal chassis is very critical and rigorous. Only by fully mastering all processes involved and complying with relevant regulations can we better ensure that the processing quality of sheet metal chassis meets the requirements. What processes will be involved in the processing of sheet metal chassis?

1、组装过程。在钣金机箱的加工中，常见的装配方式有地纹装配法、复制装配法、立式、立柱式和倒句装配法。

1. Assembly process. In the processing of sheet metal chassis, the common assembly methods are ground pattern assembly, copy assembly, vertical assembly, column assembly and inverted sentence assembly.

2、切割工艺。钣金底盘加工的下料工序，关键是根据已经完成施工放样的图纸对材料进行下料。通常切割方式有：手工切割、机械设备切割、下料件加工、数控火焰切割、低温等离子氧切割切割等。切割时可根据不同的技术标准进行选择，大规模的规模和成本。下料方式不同，根据图纸对边角料进行切割加工等因素也会有不同的选择。

2. Cutting process. For the blanking process of sheet metal chassis processing, the key is to blanking the materials according to the drawings that have completed the construction setting out. The usual cutting methods are: manual cutting, mechanical equipment cutting, blanking parts processing, CNC flame cutting, low-temperature plasma oxygen cutting, etc. Cutting can be selected according to different technical standards, large-scale scale scale and cost. With different cutting methods, there will be different choices for cutting and processing of leftover materials according to the drawings.

3、成型工艺。山东钣金制造厂家提醒大家，成型工艺是钣金底盘加工中非常核心的阶段。设计方案规范对提高加工效率和产品质量，控制成本具有极其重要的作用。其成型工艺包括：

3. Forming process. Shandong sheet metal manufacturers remind us that the forming process is a very core stage in the processing of sheet metal chassis. Design scheme specification plays an extremely important role in improving processing efficiency, product quality and cost control. The forming process includes:

人体成型、机械设备成型、顶压成型、爆破等。其中，人力是传统钣金工必须掌握的技能；机械设备成型是现在特别普遍的工艺，折弯设备和模具，完成钣金工件的成型。

Human body forming, mechanical equipment forming, top pressing forming, blasting, etc. Among them, manpower is a professional skill that traditional sheet metal workers must master; Mechanical equipment forming is now a particularly common process, bending equipment and molds to complete the forming of sheet metal workpiece.

在钣金机箱加工过程中，要注意以下几个方面：

During the processing of sheet metal chassis, pay attention to the following aspects:

折弯时，钣金底盘的生产加工要按照工程图纸上的规范进行。钣金机箱加工过程中，应在折弯、铆接等工序后进行表面处理。不同的材料有不同的表面处理方法。冷轧钢板生产加工后，一般要进行表面电镀工艺。电镀后不进行喷漆处理。对基体表面进行清洗、脱油、涂漆。不锈钢板在折弯前可以用金属拉丝完成，但没有喷过。如果需要喷涂，则需要打毛；为不同颜色的喷漆选择不同的空气氧化底色。

During bending, the production and processing of the sheet metal chassis shall be carried out in accordance with the specifications on the engineering drawings. During the processing of sheet metal chassis, the surface treatment shall be carried out after bending, riveting and other processes. Different materials have different surface treatment methods. After the production and processing of cold rolled steel plate, the surface electroplating process is generally carried out. Paint spraying is not required after electroplating. Clean, degrease and paint the substrate surface. The stainless steel plate can be finished with metal drawing before bending, but it has not been sprayed. If spraying is required, roughening is required; Choose different air oxidation base colors for different colors of paint.

钣金机箱加工过程中，通常要实现下料后才能进入下一道工序。不同的工件根据生产加工的要求进入相应的工序。有折弯、铆接、反攻、焊接、闪光、高低差等。有时螺栓或螺柱要折弯一两次后压紧，中间有模壳飞边和高低差。必须先考虑生产加工，防止生产后其他工艺流程干扰病害，无法进行所需的生产加工。上盖或下壳有挂钩时，如果折弯后不能对焊，则必须在折弯前生产加工。

During the processing of sheet metal chassis, it is usually necessary to realize blanking before entering the next process. Different workpieces enter the corresponding process according to the requirements of production and processing. There are bending, riveting, counter attack, welding, flashing, height difference, etc. Sometimes the bolts or studs should be bent once or twice and then pressed tightly, with the flash and height difference of the mold shell in the middle. Production and processing must be considered first to prevent other technological processes from interfering with diseases after production, and the required production and processing cannot be carried out. If the upper cover or lower shell has a hook and cannot be butt welded after bending, it must be produced and processed before bending.

总的来说，我们可以看到钣金机箱加工一般涉及到装配、下料、成型三个工序。更多相关内容你可以关注我们的网站m.metferro.com，查看资讯，联系我们满足选购需求！
