仿威图机柜作为工业控制设备的核心载体，其标准化生产流程是保障产品质量与交付效率的关键。从原材料选型到成品出库，整个过程通过精细化分工与严格品控，实现规模化生产与定制化需求的平衡。

　　As the core carrier of industrial control equipment, the standardized production process of the imitation Weitu cabinet is the key to ensuring product quality and delivery efficiency. From raw material selection to finished product delivery, the entire process achieves a balance between large-scale production and customized needs through refined division of labor and strict quality control.

　　原材料选用与检验

　　Raw material selection and inspection

　　生产始于冷轧钢板的选用，材质需符合GB/T 708-2019标准，厚度公差控制在±0.05mm以内。钢板入库前需通过三道检验：，光谱分析仪检测元素成分，确保碳、锰含量符合耐腐蚀要求；第二，拉伸试验机测试抗拉强度与屈服强度，数据需达到345MPa以上；第三，盐雾试验箱模拟48小时腐蚀环境，表面锈蚀面积不得超过0.5%。

　　Production begins with the selection of high-quality cold-rolled steel plates, which must comply with the GB/T 708-2019 standard and have a thickness tolerance controlled within ± 0.05mm. Before the steel plate is stored, it needs to undergo three inspections: firstly, the elemental composition is detected by a spectrometer to ensure that the carbon and manganese content meets the corrosion resistance requirements; Secondly, the tensile testing machine is used to test the tensile strength and yield strength, and the data must be above 345MPa; Thirdly, the salt spray test chamber simulates a 48 hour corrosive environment, and the surface rust area shall not exceed 0.5%.

　　数控加工与折弯成型

　　Numerical Control Machining and Bending Forming

　　采用全自动数控冲床进行板材切割，模具间隙精确0.1mm，孔位误差控制在±0.02mm范围内。对于异形开孔，引入激光切割机实现动态焦距补偿，确保切割面垂直度≤1°。折弯工序由数控折弯机完成，通过角度补偿算法控制回弹变形，单次折弯角度误差不超过0.5°，多道折弯累计误差控制在1°以内。

　　Using fully automatic CNC punching machines for sheet cutting, the mold clearance is precise to 0.1mm, and the hole position error is controlled within ± 0.02mm. For irregular openings, a laser cutting machine is introduced to achieve dynamic focal length compensation, ensuring that the perpendicularity of the cutting surface is ≤ 1 °. The bending process is completed by a CNC bending machine, and the rebound deformation is controlled by an angle compensation algorithm. The single bending angle error does not exceed 0.5 °, and the cumulative error of multiple bending is controlled within 1 °.

　　焊接与表面处理

　　Welding and surface treatment

　　焊接环节采用机器人自动化焊接工作站，焊缝轨迹规划基于三维模型离线编程，焊接速度稳定在800mm/min，熔深控制在3-5mm区间。关键承重部位实施双面焊接，破坏性试验显示焊缝抗拉强度达母材85%以上。表面处理采用型前处理工艺，脱脂、表调、磷化三道工序后，磷化膜重达到2-3g/m²。静电喷塑选用聚酯粉末涂料，膜厚控制在60-80μm，经百格试验附着力达0级标准。

　　The welding process adopts a robot automated welding workstation, and the weld trajectory planning is based on offline programming of 3D models. The welding speed is stable at 800mm/min, and the penetration depth is controlled within the range of 3-5mm. Double sided welding is implemented in key load-bearing areas, and destructive tests show that the tensile strength of the weld seam reaches over 85% of the base metal. The surface treatment adopts an environmentally friendly pre-treatment process, which includes three steps of degreasing, surface adjustment, and phosphating. After that, the weight of the phosphating film reaches 2-3g/m². Polyester powder coating is selected for electrostatic spraying, with a film thickness controlled at 60-80 μ m, and the adhesion strength reaches the 0 level standard after the hundred grid test.

　　装配与调试

　　Assembly and Debugging

　　标准化装配流程包含七个工位：进行门板铰链预装配，通过扭矩扳手控制预紧力在12-15N·m；接着安装承重导轨，水平度偏差≤0.2mm/m；然后进行密封条贴合，采用进口双面胶带确保IP55防护等级；随后进行模块化安装，强电/弱电区域分隔间距符合IEC 60529标准；再进行线缆管理，使用尼龙扎带固定，弯曲半径不小于线径6倍；接着进行接地连续性测试，电阻值≤0.1Ω；进行功能调试，模拟满载工况运行24小时，温控范围需保持在-10℃60℃之间。

　　The standardized assembly process includes seven workstations: firstly, the door panel hinges are pre assembled, and the pre tightening force is controlled at 12-15N · m through a torque wrench; Next, install the load-bearing guide rail with a horizontal deviation of ≤ 0.2mm/m; Then, the sealing strip is attached and imported double-sided tape is used to ensure an IP55 protection level; Subsequently, modular installation will be carried out, and the separation distance between strong and weak electrical areas will comply with the IEC 60529 standard; Perform cable management again, fix with nylon zip ties, and the bending radius should not be less than 6 times the wire diameter; Next, conduct a grounding continuity test with a resistance value of ≤ 0.1 Ω; Finally, perform functional debugging and simulate full load operation for 24 hours. The temperature control range should be maintained between -10 ℃ and 60 ℃.

　　成品检验与包装

　　Finished product inspection and packaging

　　成品检验包含23项检测项目，包括：门板开启耐久性试验达10000次无变形，锁具防盗等级通过EN 1300 B级认证，抗震性能满足IEC 60068-2-27标准。包装环节采用蜂窝纸板，内部使用EPE缓冲材料，包装箱跌落试验从1.2米高度自由落体后，机柜变形量不超过2mm。

　　The finished product inspection includes 23 testing items, with a focus on the durability test of the door panel reaching 10000 times without deformation, the anti-theft level of the lock passing the EN 1300 B-level certification, and the seismic performance meeting the IEC 60068-2-27 standard. Environmentally friendly honeycomb cardboard is used in the packaging process, with EPE cushioning material used internally. After the packaging box falls freely from a height of 1.2 meters, the deformation of the cabinet does not exceed 2mm.
