Solution Overview
Problem
Existing methods for cleaning and surface treatment of metal components, particularly those with complex shapes, are inefficient and non-uniform, and cannot achieve full-surface compaction, leading to time-consuming processes and material property inconsistencies.
Innovation Solution
A method using ceramic blasting particles applied uniformly across the entire surface of metal components through a processing area, facilitated by centrifugal wheels and a transport system that allows for all-around treatment, with optional ultrasonic cleaning for thorough residue removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a directed particle beam is used to clean metal surfaces, then a limited area can be treated, but the treatment is time-consuming and non-uniform when applied to entire surfaces
Solution Approach 1:
Instead of directing the particle beam at the workpiece from a fixed position, the invention inverts the approach by rotating the workpiece itself within the particle beam. The workpiece is mounted on a rotating carrier that spins it through the blasting material flow, ensuring all surfaces are uniformly exposed to the particles simultaneously, thereby achieving both complete coverage and treatment uniformity in a single operation.
Solution Approach 2:
The invention transitions from a one-dimensional directed beam approach to a three-dimensional treatment by introducing rotation of the workpiece. This rotational movement adds temporal and spatial dimensions to the treatment process, allowing particles to attack the surface from multiple angles and orientations, thereby achieving uniform treatment across complex geometries without requiring multiple passes.
2Quantity of substance
If a directed particle beam is used for surface treatment, then a limited area is processed at once, but achieving full-surface treatment requires multiple passes
Solution Approach 1:
The workpiece is rotated within the particle beam rather than moving the beam across the workpiece. This inversion allows the entire surface to be exposed to the blasting material simultaneously through continuous rotation, achieving complete surface coverage in a single continuous operation without requiring multiple passes or systematic coverage movements.
Solution Approach 2:
The rotating workpiece enables continuous exposure of all surfaces to the particle beam without interruption. The rotation ensures that every part of the workpiece passes through the treatment zone continuously, maintaining constant useful action across the entire surface area, thereby eliminating the need for repeated passes and reducing total processing time.
3Adaptability or versatility
If conventional blasting devices are used, then simple flat surfaces can be treated, but complex-shaped components cannot be uniformly treated
Solution Approach 1:
Instead of directing particles at stationary or linearly moved workpieces, the invention rotates complex-shaped components within the particle beam. This rotation ensures that all surfaces, including recesses and complex geometries, are uniformly exposed to the blasting material from multiple angles, achieving consistent treatment across diverse shapes without requiring shape-specific tooling or positioning.
Solution Approach 2:
The invention handles complex three-dimensional shapes by introducing rotational movement in addition to the particle beam direction. This creates a multi-dimensional treatment approach where particles can access and treat all surfaces of complex geometries uniformly, regardless of their orientation or complexity, thereby achieving both adaptability to various shapes and treatment uniformity.
4Manufacturing precision
If ceramic blasting particles are used, then effective cleaning and surface densification are achieved, but device wear increases rapidly
Solution Approach 1:
The invention extracts the workpiece from the particle stream after treatment and separates it from the blasting chamber. The ceramic particles are contained within the blasting chamber and do not come into contact with the workpiece in a way that causes device wear. The workpiece is rotated within the chamber and then removed, leaving the expensive ceramic particles and blasting chamber intact for reuse, thereby achieving surface densification without sacrificing device durability.
Solution Approach 2:
The rotating workpiece acts as an intermediary that receives the full force of the ceramic particles during rotation but is then removed from the blasting chamber. This allows the ceramic particles to perform their function of surface densification and cleaning effectively while preventing them from causing wear to the device components, as the workpiece absorbs the particle impact and is subsequently extracted from the system.
