自動式拋丸機作為工業表面處理領域的關鍵設備，通過機械自動化方式實現對工件表面的清理、強化等加工，廣泛應用于制造業的多個環節。其高效的作業能力與穩定的性能，使其成為替代人工除銹、打磨的重要選擇，在提升生產效率的同時，保證了處理質量的一致性。

　　As a key equipment in the field of industrial surface treatment, automatic shot blasting machines achieve cleaning, strengthening and other processing of workpiece surfaces through mechanical automation, and are widely used in multiple aspects of manufacturing. Its efficient operational capability and stable performance make it an important alternative to manual rust removal and polishing, ensuring consistency in processing quality while improving production efficiency.

　　在工業生產中，自動式拋丸機的核心作用體現在表面清理與預處理上。對于金屬工件（如鋼板、鑄件、鋼結構件），它能通過高速噴射的彈丸（鋼丸、鐵丸等）沖擊表面，去除氧化皮、鐵銹、油污及鑄造殘留物，為后續的涂裝、電鍍等工藝奠定基礎。例如，汽車制造中，車身框架在焊接后需經拋丸處理，清除焊縫處的焊渣與氧化層，確保油漆涂層能緊密附著，延長車身使用壽命；在船舶制造領域，船體鋼板預處理時，拋丸機可一次性完成除銹與粗化處理，使防腐涂層的附著力提升 30% 以上。對于非金屬材料（如玻璃、石材），拋丸機通過調整彈丸材質與噴射強度，能實現表面毛化處理，增強材料的防滑性或美觀度，如建筑裝飾用的石材表面，經拋丸處理后形成均勻的粗糙紋理，兼具實用與裝飾效果。

　　In industrial production, the core role of automatic shot blasting machines is reflected in surface cleaning and pretreatment. For metal workpieces (such as steel plates, castings, and steel structural components), they can be impacted by high-speed projectiles (steel balls, iron balls, etc.) to remove oxide scales, rust, oil stains, and casting residues, laying the foundation for subsequent painting, electroplating, and other processes. For example, in automobile manufacturing, the body frame needs to undergo shot blasting treatment after welding to remove welding slag and oxide layer at the weld seam, ensuring that the paint coating can adhere tightly and extending the service life of the body; In the field of shipbuilding, during the pre-treatment of ship hull steel plates, shot blasting machines can complete rust removal and roughening treatment in one go, increasing the adhesion of anti-corrosion coatings by more than 30%. For non-metallic materials such as glass and stone, shot blasting machines can achieve surface roughening treatment by adjusting the material and spray intensity of the shot, enhancing the material's anti slip or aesthetic properties. For example, the surface of stone used for architectural decoration can form a uniform rough texture after shot blasting treatment, which has both practical and decorative effects.

　　表面強化是自動式拋丸機的另一重要作用。通過彈丸的高速撞擊，工件表面會產生塑性變形，形成一定厚度的硬化層，提高材料的疲勞強度與耐磨性。在機械制造中，齒輪、彈簧等承受交變載荷的零件，經拋丸強化后，使用壽命可延長 2-3 倍；高鐵軌道扣件通過拋丸處理，能有效抵抗列車運行時的振動磨損，保障軌道系統的穩定性。這種強化方式無需改變工件的整體性能，僅通過表面改性即可提升關鍵部位的力學性能，尤其適合對重量、精度有嚴格要求的零部件。

　　Surface strengthening is another important function of automatic shot blasting machines. Through the high-speed impact of the projectile, the surface of the workpiece will undergo plastic deformation, forming a certain thickness of hardened layer, which improves the fatigue strength and wear resistance of the material. In mechanical manufacturing, parts such as gears and springs that withstand alternating loads can have their service life extended by 2-3 times after shot blasting strengthening; The high-speed rail track fasteners can effectively resist vibration and wear during train operation through shot blasting treatment, ensuring the stability of the track system. This strengthening method does not require changing the overall performance of the workpiece, and only surface modification can improve the mechanical properties of key parts, especially suitable for components with strict requirements for weight and accuracy.

　　自動式拋丸機的自動化特性是其區別于手動設備的核心優勢。設備配備的輸送系統（如輥道、鏈條、吊鉤）能自動完成工件的上料、定位、輸送與下料，無需人工干預，可實現連續化生產。例如，批量處理螺栓、螺母等小型零件時，振動輸送裝置將工件均勻送入拋丸室，處理完成后自動排出，每小時可處理數千件，效率遠超人工打磨。控制系統通過 PLC 編程實現參數設定與調節，操作人員可根據工件材質、尺寸預設彈丸流量、噴射角度、處理時間等參數，確保不同批次工件的處理效果一致，避免人工操作導致的質量波動。部分高端設備還配備傳感器與視覺系統，能實時監測工件表面狀態，自動調整作業參數，進一步提升處理精度。

　　The automation feature of an automatic shot blasting machine is its core advantage that distinguishes it from manual equipment. The conveying system equipped with the equipment (such as roller conveyors, chains, and hooks) can automatically complete the loading, positioning, conveying, and unloading of workpieces without manual intervention, achieving continuous production. For example, when batch processing small parts such as bolts and nuts, the vibration conveying device evenly sends the workpieces into the shot blasting chamber, and automatically discharges them after processing. It can process thousands of pieces per hour, with efficiency far exceeding manual polishing. The control system achieves parameter setting and adjustment through PLC programming. Operators can preset parameters such as projectile flow rate, spray angle, and processing time based on the material and size of the workpiece, ensuring consistent processing effects for different batches of workpieces and avoiding quality fluctuations caused by manual operations. Some high-end equipment is also equipped with sensors and vision systems, which can monitor the surface condition of workpieces in real time, automatically adjust operating parameters, and further improve processing accuracy.

　　高效節能是自動式拋丸機的顯著特性。與傳統的酸洗、噴砂工藝相比，拋丸處理無需使用化學藥劑，減少了廢水、廢氣排放，符合環保要求；彈丸可循環利用（回收率達 95% 以上），降低了耗材成本。設備的拋丸器采用高效電機驅動，彈丸噴射速度可達 60-80 米 / 秒，單臺拋丸器每小時可處理 10-50 平方米的工件表面，能耗僅為人工處理的 1/3。此外，封閉式的拋丸室設計能有效控制粉塵與噪音，粉塵排放濃度可控制在 10mg/m 以下，噪音低于 85 分貝，改善了作業環境，減少了對操作人員的健康影響。

　　High efficiency and energy saving are significant characteristics of automatic shot blasting machines. Compared with traditional pickling and sandblasting processes, shot blasting treatment does not require the use of chemical agents, reduces wastewater and exhaust emissions, and meets environmental protection requirements; The pellets can be recycled (with a recovery rate of over 95%), reducing the cost of consumables. The shot blasting machine of the equipment is driven by an efficient motor, and the projectile spraying speed can reach 60-80 meters per second. A single shot blasting machine can process 10-50 square meters of workpiece surface per hour, with energy consumption only one-third of manual processing. In addition, the enclosed shot blasting room design can effectively control dust and noise, with dust emission concentration controlled below 10mg/m and noise below 85 decibels, improving the working environment and reducing the impact on the health of operators.

　　適應性強是自動式拋丸機的另一突出特性。通過更換不同規格的彈丸（直徑 0.2-3 毫米）與調整拋丸器布局，可處理多種形狀與尺寸的工件，從細小的五金件到大型的鋼結構構件均可適配。例如，履帶式拋丸機適合處理不怕碰撞的中小型工件（如鑄件），吊鉤式拋丸機則用于大型工件（如機床床身）的全方位處理，滾筒式拋丸機則適用于批量小件的翻滾清理。設備還可根據工件材質選擇彈丸類型：清理鑄鐵件時選用鑄鐵丸，強化高強度鋼件時選用高碳鋼丸，處理鋁合金件時則選用鋁丸或玻璃丸，避免損傷工件表面。

　　Strong adaptability is another prominent feature of automatic shot blasting machines. By replacing pellets of different specifications (diameter 0.2-3 millimeters) and adjusting the layout of the shot blasting device, it can handle workpieces of various shapes and sizes, from small hardware components to large steel structural components that can be adapted. For example, track type shot blasting machines are suitable for handling small and medium-sized workpieces (such as castings) that are not afraid of collisions, hook type shot blasting machines are used for comprehensive processing of large workpieces (such as machine bed frames), and drum type shot blasting machines are suitable for rolling cleaning of small batch workpieces. The equipment can also choose the type of projectile based on the material of the workpiece: cast iron pellets are used for cleaning cast iron parts, high carbon steel pellets are used for strengthening high-strength steel parts, and aluminum or glass pellets are used for processing aluminum alloy parts to avoid damaging the surface of the workpiece.
