During the machining of large castings, residual chips, abrasive particles, metal shavings, and liquids such as cutting fluid and rust-preventive oil remain. If not cleaned and removed, these hard particles and stains can significantly impact the quality of subsequent processes, such as instrument testing, surface coating, and assembly. Furthermore, large components are often core parts of assemblies, and product quality cannot be neglected; the cleanliness of component surfaces is paramount. Cleaning is not only about removing visible iron filings and oil stains, but also about controlling microscopic particulate contamination to ensure mechanical lifespan, reliability, and the feasibility of subsequent processes.
Large castings, regardless of whether they are made of iron, steel, aluminum, or alloys, inevitably contain numerous connecting and fixing holes, guide holes, and shell cavities. Accumulation of dirt and grime after processing is unavoidable, making cleaning and rinsing labor-intensive and difficult. Cleaning large parts is mostly done manually, and due to their size and weight, this work presents significant challenges for operators in harsh working conditions.
Compared to cleaning small parts, cleaning large castings after machining presents the following problems:
1. Large equipment size and large footprint;
2. Immersion cleaning: large cleaning tank, large amount of solution, high energy consumption;
3. High-pressure rinsing: large discharge, low efficiency, high labor intensity, and poor working environment.
Traditional manual cleaning methods are inefficient and struggle to remove hidden dirt from blind holes and cavities, failing to meet cleanliness requirements. The application of large-scale spray cleaning equipment effectively solves these pain points in cleaning large castings. Custom-designed spray cleaning equipment for large castings can adjust the spray angle and pressure according to the workpiece’s size and structure. Through high-pressure, multi-directional spraying, combined with specialized metal cleaning agents, it can quickly wash away residual chips, abrasive particles, and oil stains from the workpiece surface and cavities. This reduces manual labor intensity, improves the working environment, consistently ensures workpiece cleanliness, significantly shortens cleaning time, and improves cleaning efficiency, perfectly matching the quality control requirements after processing large castings.
The entire machine is centrally controlled by a PLC, and all operating parameters are set via a touchscreen. The operator uses lifting tools to place the processed large castings onto the rotating tray. The spray pipes are arranged in multiple directions. After the rotating track door is manually closed, the equipment enters the cleaning state. The rotating tray can rotate 360 degrees, completing the rinsing of the parts within the set time and issuing a completion status indication. The cleaning liquid is recycled through a filtration system.
