Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pneumatic tool accessories production, in particular to a tool for polishing the inner wall of a pneumatic tool die-casting sleeve. Background Art
[0002] The main advantages of using die-cast sleeves in positive displacement piston pneumatic tools include: 1) Die-cast sleeves typically have high strength and hardness, capable of withstanding the high pressure and impact forces generated during pneumatic tool operation, thereby improving tool durability and service life. 2) Die-cast sleeves provide a better seal, preventing compressed air leakage and ensuring the stability and efficiency of the pneumatic tool. This is crucial for maintaining the proper functioning of the pneumatic system and reducing energy waste. 3) The die-casting process ensures high-precision manufacturing of the sleeve, resulting in a tighter fit with other pneumatic tool components, reducing wear and failure. 4) The relatively simple production process for die-cast sleeves allows for mass production, reducing production costs. This is a significant competitive advantage for manufacturers and also enables users to provide more cost-effective pneumatic tools. 5) Die-cast sleeves can be customized to suit different pneumatic tool requirements, adapting to various working environments and task demands. This flexibility enables pneumatic tools to be used in a wider range of industries. The relatively simple structure of die-cast sleeves makes them easy to disassemble and replace, reducing the difficulty and cost of pneumatic tool maintenance. This is important to ensure continued operation of your pneumatic tools and minimize downtime.

First, they cannot quickly remove debris generated during the polishing process; second, they cannot spray a wear-resistant coating onto the inner surface of the die-cast sleeve during the polishing process. Therefore, optimization and improvement are needed. Utility Model Content
