Thermal Deburring Machine With Movable Chamber
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing thermal deburring machines are heavy, bulky, costly, and slow due to the need for a strong press with a long piston stroke to withstand explosions and handle large workpieces, limiting their efficiency and productivity.
Innovation Solution
A thermal deburring machine with a horizontal-axis press and a moveable, cylindrical deburring chamber that can be extracted from the press for loading and unloading, using a chamber holder and hydraulic or mechanical means to apply force efficiently, and incorporating a palletised and robotised system for faster operation cycles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a strong press with vertical axis and fixed deburring chamber is used to withstand the explosion, then the machine can handle the explosion force, but the machine becomes heavy, bulky and costly
Solution Approach 1:
The machine is divided into separate functional components: the press structure provides explosion resistance, while the deburring chamber is made movable and separable. This segmentation allows the heavy press to remain stationary while the lighter chamber is moved in and out, reducing the overall machine footprint and apparent weight requirements.
Solution Approach 2:
The deburring chamber transitions from a fixed position to a movable position, being inserted into and removed from the press. This dynamic configuration allows the system to achieve explosion resistance only when needed (chamber inserted), while maintaining operational flexibility and reduced size when the chamber is removed.
2Force
If a piston with long stroke (150-300 mm) is used to press the closing plate against the deburring chamber, then the press can exert sufficient force (180-350 tons), but the machine becomes slow
Solution Approach 1:
The pressing action is achieved through a different mechanical arrangement that reduces the stroke length requirement. By changing the dimensional approach of the pressing mechanism, the system can generate the same high force (180-350 tons) with a shorter piston stroke, thereby increasing operating speed.
3Device complexity
If the deburring chamber is fixed in the press, then the machine structure is simple, but the loading and unloading process is slow
Solution Approach 1:
The deburring chamber is made movable rather than fixed, allowing it to be inserted into and removed from the press quickly. This dynamic configuration enables fast loading and unloading operations while maintaining a relatively simple overall machine structure through the use of guide rails and positioning mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The machine reduces the length of the piston stroke, increases operating speed, and decreases the machine's size, resulting in improved productivity and efficiency by allowing faster loading/unloading and reducing the overall cycle time.
Implementation Method 1
the piston makes a stroke of 150-300 mm and presses the plate against the deburring chamber with a force of 180-350 tons
Implementation Method 2
the burs are oxidised through the effect of the excess oxygen present in the deburring chamber and vaporise
Implementation Method 3
the burs are oxidised through the effect of the excess oxygen present in the deburring chamber and vaporise
