自動噴砂房的核心原理及主要用途
自動噴砂房是工業表面處理的高效設備，通過機械自動化控制完成工件表面噴砂，保證處理質量一致，廣泛應用于金屬加工、機械制造等領域，為后續工序提供優質表面基礎。
Automatic sandblasting room is an efficient equipment for industrial surface treatment, which completes sandblasting of workpiece surfaces through mechanical automation control, ensuring consistent treatment quality. It is widely used in metal processing, mechanical manufacturing and other fields, providing high-quality surface foundation for subsequent processes.
其核心原理是利用壓縮空氣驅動磨料高速噴射，對工件表面產生沖擊與切削作用。壓縮空氣系統將空氣壓縮至 0.4-0.8MPa，輸送至噴砂槍，儲砂罐內的磨料進入噴砂槍與高速氣流混合，形成 50-100 米 / 秒的高速噴射束，剝離工件表面雜質，形成均勻粗糙面。不同磨料適用不同場景：鋼丸適合去厚銹或強化表面，石英砂適用于精密工件清理，玻璃珠可處理鋁合金等易損材料。
The core principle is to use compressed air to drive high-speed abrasive spraying, which produces impact and cutting effects on the surface of the workpiece. The compressed air system compresses the air to 0.4-0.8 MPa and delivers it to the sandblasting gun. The abrasive in the sand storage tank enters the sandblasting gun and mixes with the high-speed airflow to form a high-speed jet beam of 50-100 meters per second, which peels off impurities on the surface of the workpiece and forms a uniform rough surface. Different abrasives are suitable for different scenarios: steel balls are suitable for removing thick rust or strengthening surfaces, quartz sand is suitable for precision workpiece cleaning, and glass beads can handle vulnerable materials such as aluminum alloys.
自動控制系統通過程序設定與傳感器協同控制噴砂過程。工件經輸送裝置進入噴砂房，光電傳感器檢測后啟動系統，多軸機械臂帶動噴砂槍根據工件形狀做三維運動，確保均勻噴射；批量相同工件可預錄程序自動完成噴砂。噴砂時間依要求控制，輕薄工件 30-60 秒，厚重工件 2-5 分鐘，系統通過計時器與傳送帶速度聯動保證處理時間一致。作業時粉塵回收系統同步啟動，負壓吸塵裝置將粉塵吸入過濾系統，凈化后空氣循環使用或達標排放，避免污染。
The automatic control system cooperates with sensors to control the sandblasting process through program settings. The workpiece enters the sandblasting room through the conveying device, and the photoelectric sensor detects and starts the system. The multi axis robotic arm drives the sandblasting gun to perform three-dimensional motion according to the shape of the workpiece, ensuring uniform spraying; Batch of identical workpieces can be pre recorded with a program to automatically complete sandblasting. The sandblasting time is controlled according to requirements, with light and thin workpieces taking 30-60 seconds and heavy workpieces taking 2-5 minutes. The system ensures consistent processing time through timer and conveyor belt speed linkage. The dust recovery system starts synchronously during homework, and the negative pressure suction device sucks the dust into the filtration system. After purification, the air is circulated or discharged in compliance with standards to avoid pollution.
金屬表面清理是其基礎應用。機械制造中，能快速去除鑄件、鍛件表面的氧化皮和型砂，為噴漆、電鍍等工序創造良好附著條件，處理后表面粗糙度 Ra 值 1.6-6.3μm。大型鋼結構除銹時，多槍協同作業 2-3 分鐘可完成 1 平方米除銹，達 Sa2.5 級標準，效率和質量穩定性遠超人工。舊件翻新時，可清除舊漆層、油污，無需化學脫漆劑，既環保又避免損傷工件。
Metal surface cleaning is its fundamental application. In mechanical manufacturing, it can quickly remove the oxide scale and molding sand on the surface of castings and forgings, creating good adhesion conditions for painting, electroplating and other processes. The surface roughness Ra value after treatment is 1.6-6.3 μ m. When removing rust from large steel structures, multiple guns working together can complete 1 square meter of rust removal in 2-3 minutes, reaching the Sa2.5 standard, with efficiency and quality stability far exceeding manual labor. When renovating old parts, the old paint layer and oil stains can be removed without the need for chemical paint removers, which is both environmentally friendly and avoids damaging the workpiece.
表面強化與改性可提升工件使用壽命。金屬表面噴丸強化將高強度鋼丸高速噴射到彈簧、齒輪等表面，使表層產生塑性變形形成殘余壓應力，提升疲勞強度，如汽車板簧經處理后壽命可提升 2-3 倍。能為離合器片、制動蹄等工件增加表面摩擦力，形成均勻麻面確保性能穩定。航空航天精密部件經噴砂可去除表面微觀裂紋，形成應力層，提升高溫高壓環境下的可靠性。
Surface strengthening and modification can improve the service life of workpieces. Shot peening on metal surfaces involves high-speed injection of high-strength steel shot onto the surfaces of springs, gears, etc., causing plastic deformation and residual compressive stress on the surface, thereby improving fatigue strength. For example, the service life of automotive leaf springs can be increased by 2-3 times after treatment. It can increase the surface friction of workpieces such as clutch plates and brake shoes, forming a uniform rough surface to ensure stable performance. Aerospace precision components can be sandblasted to remove surface micro cracks, form stress layers, and improve reliability in high temperature and high pressure environments.
特殊材料處理拓展了應用范圍。玻璃加工中，細粒度玻璃珠噴砂形成磨砂效果，用于建筑、家具玻璃裝飾，比化學蝕刻更環保靈活。陶瓷制品噴砂可去釉面缺陷或形成啞光質感，提升外觀。復合材料成型后，用軟質磨料可精準去除表面樹脂殘渣，不損傷纖維結構，保證力學性能。
Special material processing has expanded its application scope. In glass processing, fine-grained glass beads are sandblasted to form a frosted effect, which is used for building and furniture glass decoration and is more environmentally friendly and flexible than chemical etching. Sandblasting ceramic products can remove glaze defects or create a matte texture, enhancing their appearance. After the formation of composite materials, soft abrasives can accurately remove surface resin residues without damaging the fiber structure, ensuring mechanical properties.

The automatic sandblasting room has achieved high efficiency, standardization, and environmental protection in surface treatment, covering multiple industrial fields, improving efficiency and quality stability, and reducing manual labor intensity and dust pollution. With the increasing demand for surface quality in industry, its upgrading in refinement and intelligence will further expand its application scenarios and provide support for the development of manufacturing industry.
