处理非标准硬件零件时如何预防坑?

在非标准硬件零件处理过程中, 防止坑是一个重要的质量控制链接. The following are some key measures and methods to ensure the processing quality of hardware parts:

1. Choose high-quality materials

材料特性: The pitting problem of hardware parts is often related to the hardness, 力量, toughness and other characteristics of the material. 所以, when purchasing materials, high-quality materials with high hardness and good dent resistance should be selected, especially for some parts with large external stress, more attention should be paid to the compressive resistance of the material.

质量检验: Strict quality inspection of materials entering the warehouse to ensure that there are no defects such as cracks and pores on the surface of the material to reduce the generation of pits during processing.

2. Optimize processing technology

Tool selection and wear management: The selection of cutting tools, 切削深度, cutting speed and cutting lubrication will affect the surface quality of hardware. Suitable tools should be selected, and severely worn tools should be checked and replaced regularly to reduce vibration and impact during processing and avoid the generation of pits.

Mold inspection and maintenance: Molds are important tools for hardware parts processing, and their status directly affects the processing quality. Molds should be inspected and maintained regularly to ensure that the mold surface is smooth and undamaged, and severely worn molds should be repaired or replaced in time.

3. Control processing parameters

切割参数: Reasonably set cutting parameters, such as cutting speed, 进给率, 等, to reduce cutting force and vibration during processing, thereby reducing the risk of pits.

Pressing parameters: 在冲压过程中, the parameters such as stamping speed and stamping force should be reasonably set to ensure that the stamping process is carried out smoothly and avoid pits on the surface of the stamped parts.

4. Strengthen process monitoring

Online detection: Use online detection technology in the processing of non-standard hardware parts to monitor the processing status in real time, and promptly discover and deal with problems that may cause pits.

Regular sampling: Regularly sample parts in processing to check whether their surface quality meets the requirements and ensure that the processing process is controlled.

5. Environmental control

Working environment: Keep the processing workshop clean and dry to avoid damage to hardware parts caused by environmental factors such as moisture and corrosion.

Equipment maintenance: Regularly maintain and maintain the processing equipment to ensure that the equipment is in good working condition and reduce processing quality problems caused by equipment failure.

6. Subsequent processing

Deburring and cleaning: After the processing of non-standard hardware parts is completed, the parts should be deburred and cleaned to remove impurities such as cutting fluid and oil residue on the surface to reduce the risk of pits.

表面处理: Sandblasting, anodizing and other surface treatments are performed on the parts as needed to improve the corrosion resistance and aesthetics of the parts.
