自动式抛丸机（Automatic Shot Blasting Machine）是一种用于表面处理的机械设备，它主要通过喷射高速金属颗粒或磨料来清理、腐蚀和强化工件表面。其工作原理包括以下几个关键步骤：

　　An automatic shot blasting machine is a mechanical equipment used for surface treatment, which mainly cleans, corrodes, and strengthens the surface of workpieces by spraying high-speed metal particles or abrasives. Its working principle includes the following key steps:　　工件进料：工件被放置在抛丸机的工作室中，可以手动放置或通过输送系统进行自动输送。

　　Workpiece feeding: The workpiece is placed in the studio of the shot blasting machine and can be manually placed or automatically conveyed through the conveying system.

　　准备工作：在开始抛丸之前，需要对工件进行一些准备工作，如清洁表面，遮盖不需要处理的部分等。

　　Preparation work: Before starting shot blasting, some preparation work needs to be done on the workpiece, such as cleaning the surface, covering the parts that do not need to be treated, etc.

　　抛丸喷射：抛丸机内部有一个抛丸喷射系统，通过电动机驱动喷丸轮高速旋转。在喷丸轮上安装有刀片，喷丸材料（例如铸钢弹丸、钢砂等）被刀片甩离，形成高速运动的弹丸流。

　　Shot blasting: The shot blasting machine has an internal shot blasting system that drives the shot blasting wheel to rotate at high speed through an electric motor. A blade is installed on the shot peening wheel, and the shot peening material (such as cast steel pellets, steel sand, etc.) is thrown away by the blade, forming a high-speed projectile flow.

　　弹丸冲击：高速运动的弹丸流被通过喷嘴喷射到工件表面上，弹丸与工件表面碰撞产生冲击力，将表面的污垢、氧化层、油漆等物质剥离或清除。

　　Bullet impact: The high-speed projectile flow is sprayed onto the surface of the workpiece through a nozzle, and the projectile collides with the workpiece surface to generate an impact force, stripping or removing surface dirt, oxide layer, paint and other substances.

　　弹丸收集和循环：抛丸机会在机器底部设置一个弹丸收集系统，将使用过的弹丸通过输送装置收集起来，然后通过清洁分级设备进行筛选和清洁，并再次送回喷丸系统进行循环使用。

　　Bullet collection and circulation: The shot blasting machine sets up a bullet collection system at the bottom of the machine, collects used bullets through a conveying device, and then screens and cleans them through cleaning and grading equipment, and sends them back to the shot blasting system for recycling.

　　除尘处理：为了避免产生大量粉尘污染环境，抛丸机通常还会配备除尘设备，通过吸尘系统将产生的粉尘和废气进行处理和净化。

　　Dust removal treatment: In order to avoid generating a large amount of dust pollution to the environment, shot blasting machines are usually equipped with dust removal equipment, which processes and purifies the generated dust and exhaust gas through a vacuum system.

　　通过以上工作步骤，自动式抛丸机可以高效地清理和处理工件表面，达到提高工件质量、增加附着力和延长工件使用寿命的目的。

　　Through the above work steps, the automatic shot blasting machine can efficiently clean and treat the surface of the workpiece, achieving the goal of improving the quality of the workpiece, increasing adhesion, and extending the service life of the workpiece.
