刹车盘自动喷漆线

刹车盘自动喷漆线是针对刹车盘（圆盘状制动部件）表面防腐、耐磨涂装设计的自动化生产线，广泛应用于汽车、工程机械等制动系统零部件制造领域。该生产线核心由上料输送单元（适配圆盘件的夹持 / 吸附式输送机构）、前处理单元（除油、除锈、钝化，部分需增加喷砂粗化以提升涂层附着力）、喷漆单元（多采用旋转式静电喷涂，适配刹车盘曲面与通风孔结构）、固化单元（高温固化炉，适配铸铁 / 铝合金基材耐热性）及检测下料单元（含涂层厚度与外观检测模块）组成，可实现刹车盘从毛坯到成品涂装的全流程自动化。

其核心工艺特点为：喷漆单元采用 “圆盘旋转 + 多喷枪环绕” 设计，确保刹车盘正反面及通风孔内壁涂层均匀（厚度误差≤3μm）；前处理阶段针对刹车盘易生锈的铸铁基材，增加磷化钝化处理（膜厚 3-5μm），提升防锈能力；固化单元采用分段控温（120-200℃，根据涂料类型调整），避免刹车盘因温差产生变形。相比人工喷漆，该生产线可将生产效率提升 4-6 倍，涂料利用率提高至 90% 以上（减少浪费），且能稳定满足制动部件的耐高温（≥200℃）、耐盐雾（≥500 小时）等性能标准。

The Brake Disc Automatic Painting Line is an automated production line designed for anti-corrosion and wear-resistant coating on the surface of brake discs (disc-shaped braking components), widely used in the manufacturing of brake system parts for automobiles, construction machinery, etc. This production line mainly consists of a feeding and conveying unit (equipped with a clamping/suction-type conveying mechanism for disc parts), a pre-treatment unit (degreasing, derusting, passivation, and some require additional sandblasting roughening to improve coating adhesion), a painting unit (mostly adopting rotary electrostatic spraying, suitable for the curved surface and ventilation hole structure of brake discs), a curing unit (high-temperature curing oven, compatible with the heat resistance of cast iron/aluminum alloy substrates), and an inspection and unloading unit (equipped with coating thickness and appearance inspection modules). It can realize the full-process automation of brake discs from blank to finished product coating.

Its core process features are as follows: the painting unit adopts a "disc rotation + multi-gun surrounding" design to ensure uniform coating on the front and back sides of the brake disc and the inner wall of the ventilation holes (thickness tolerance ≤3μm); in the pre-treatment stage, aiming at the cast iron substrate of brake discs that is prone to rust, phosphating and passivation treatment (film thickness 3-5μm) is added to improve rust resistance; the curing unit adopts segmented temperature control (120-200℃, adjusted according to the type of coating) to avoid deformation of the brake disc due to temperature difference. Compared with manual painting, this production line can increase production efficiency by 4-6 times, improve coating utilization rate to more than 90% (reducing waste), and stably meet the performance standards of brake components such as high temperature resistance (≥200℃) and salt spray resistance (≥500 hours).
