高压去毛刺清洗机凭借高压水流的冲击力,能快速清除工件表面及内腔的毛刺、碎屑等杂质,其高效除渣的关键在于对设备参数、清洗介质及操作方式的精准把控,这些窍门直接影响着清洗效果与工件洁净度。
The high-pressure deburring cleaning machine, relying on the impact force of high-pressure water flow, can quickly remove burrs, debris and other impurities on the surface and inner cavity of the workpiece. The key to its efficient slag removal lies in the precise control of equipment parameters, cleaning media and operation methods, which directly affect the cleaning effect and workpiece cleanliness.
压力与流量的动态匹配是高效除渣的基础。不同材质、结构的工件需要适配不同的压力参数:对于铝合金、塑料等较软材质的工件,过高的压力可能导致表面损伤,通常将压力控制在 5-15MPa;而钢铁等硬质材料工件,可提升至 20-30MPa 以增强冲击力,确保毛刺剥离。同时,流量需与压力协同调节,例如在清洗带有深孔、盲孔的复杂工件时,需在保证压力的前提下提高流量,使水流能充分进入孔道深处,将碎屑带出。实际操作中,可通过逐步微调压力旋钮,观察工件表面的渣屑剥离状态,找到既能除净杂质又不损伤工件的最佳参数组合。
The dynamic matching of pressure and flow rate is the foundation for efficient slag removal. Workpieces of different materials and structures need to be adapted to different pressure parameters: for softer materials such as aluminum alloy and plastic, excessive pressure may cause surface damage, and the pressure is usually controlled within 5-15MPa; For hard materials such as steel workpieces, the pressure can be increased to 20-30 MPa to enhance the impact force and ensure burr removal. At the same time, the flow rate needs to be adjusted in conjunction with the pressure. For example, when cleaning complex workpieces with deep or blind holes, the flow rate needs to be increased while ensuring the pressure, so that the water flow can fully enter the deep hole and carry out the debris. In practical operation, the optimal parameter combination that can remove impurities without damaging the workpiece can be found by gradually adjusting the pressure knob and observing the slag peeling state on the surface of the workpiece.
清洗液的科学选择与配比能强化除渣效果。清水虽可用于基础清洗,但添加适量助剂能显著提升效率:针对油性切削液残留的工件,可加入中性乳化剂,增强水流对油污的乳化能力,使附着的碎屑随油污一同脱离;对于易氧化的金属工件,添加防锈剂的清洗液不仅能除渣,还能在工件表面形成保护膜,避免二次锈蚀。清洗液的浓度需根据杂质污染程度调整,浓度过高可能导致残留物附着,过低则难以发挥助剂作用,通常以 3%-5% 的浓度为宜,且需定期更换以保持活性。
The scientific selection and ratio of cleaning solution can enhance the slag removal effect. Although clean water can be used for basic cleaning, adding an appropriate amount of additives can significantly improve efficiency. For workpieces with residual oily cutting fluid, neutral emulsifiers can be added to enhance the emulsification ability of water flow on oil stains, allowing attached debris to detach with the oil stains; For metal workpieces that are prone to oxidation, cleaning solutions with rust inhibitors can not only remove slag, but also form a protective film on the surface of the workpiece to avoid secondary rusting. The concentration of the cleaning solution needs to be adjusted according to the degree of impurity contamination. If the concentration is too high, it may cause residue to adhere, while if it is too low, it may be difficult to exert the effect of an auxiliary agent. Generally, a concentration of 3% -5% is recommended, and it needs to be replaced regularly to maintain activity.
喷嘴类型与角度的精准适配决定着水流的靶向性。扁平喷嘴适合清除平面工件的表面毛刺,其扇形水流能覆盖较大面积,提升清洗速度;旋转喷嘴通过高速旋转产生螺旋状水流,适合深孔、交叉孔等复杂结构,水流在孔内形成涡流,可将藏匿的碎屑冲刷出来;锥形喷嘴则适用于精密零件的局部强化清洗,集中的水流能精准冲击微小毛刺。安装时需根据工件外形调整喷嘴角度,例如清洗齿轮齿面时,将喷嘴倾斜 30°-45°,使水流方向与齿面形成剪切力,更易剥离齿根处的碎屑,避免直射导致的水流反弹带走杂质不彻底。
The precise adaptation of nozzle type and angle determines the targeting of water flow. Flat nozzles are suitable for removing surface burrs on flat workpieces, and their fan-shaped water flow can cover a large area, improving cleaning speed; The rotating nozzle generates a spiral water flow through high-speed rotation, which is suitable for complex structures such as deep holes and cross holes. The water flow forms eddies inside the holes, which can flush out hidden debris; The conical nozzle is suitable for local reinforcement cleaning of precision parts, and the concentrated water flow can accurately impact small burrs. During installation, the nozzle angle should be adjusted according to the shape of the workpiece. For example, when cleaning the gear tooth surface, tilt the nozzle at an angle of 30 ° -45 ° to create a shear force between the water flow direction and the tooth surface, making it easier to peel off debris at the tooth root and avoiding incomplete removal of impurities caused by direct water flow rebound.
工件固定与清洗路径的优化可减少清洗盲区。不规则工件需通过定制工装夹具固定,确保在清洗过程中不晃动,同时使毛刺、渣屑聚集的部位完全暴露在水流覆盖范围内。对于批量清洗的工件,可采用分层摆放或旋转工作台,让每个工件都能均匀接受水流冲击。清洗路径的规划同样重要,例如清洗阀体类工件时,应遵循 “先内腔后表面、先孔道后平面” 的顺序,先利用高压水流疏通内部通道,再处理外部残留,避免内部冲出的碎屑二次附着在已清洗的表面。
The optimization of workpiece fixation and cleaning path can reduce cleaning blind spots. Irregular workpieces need to be fixed with customized fixtures to ensure that they do not shake during the cleaning process, while fully exposing the areas where burrs and debris accumulate within the water flow coverage range. For batch cleaned workpieces, layered placement or rotating workbenches can be used to ensure that each workpiece can uniformly receive water flow impact. The planning of the cleaning path is equally important. For example, when cleaning valve body workpieces, the order of "inner cavity first, surface second, hole first, plane second" should be followed. First, high-pressure water flow should be used to clear the internal channels, and then external residues should be treated to avoid the secondary attachment of debris washed out from the interior to the cleaned surface.
清洗后的废液处理与设备维护能保障持续高效。设备配备的过滤系统需定期清理,例如更换滤芯、清洗滤网,防止截留的碎屑堵塞管路,影响水流压力;对于含有大量金属碎屑的废液,可通过沉淀、磁选等方式分离杂质,既减少环境污染,又能回收可利用的金属颗粒。此外,每周需检查高压泵的运行状态,确保其输出压力稳定,同时对喷嘴进行磨损检查,发现孔径变大或变形时及时更换,避免因设备损耗导致的除渣效率下降。
The treatment of waste liquid after cleaning and equipment maintenance can ensure sustained efficiency. The filtering system equipped with the equipment needs to be regularly cleaned, such as replacing the filter element and cleaning the filter screen, to prevent trapped debris from blocking the pipeline and affecting the water flow pressure; For waste liquids containing a large amount of metal debris, impurities can be separated through precipitation, magnetic separation, and other methods to reduce environmental pollution and recover usable metal particles. In addition, the operation status of the high-pressure pump should be checked weekly to ensure stable output pressure. At the same time, the nozzle should be inspected for wear and tear. If the aperture becomes larger or deformed, it should be replaced in a timely manner to avoid a decrease in slag removal efficiency caused by equipment wear and tear.
