Ram Load Pattern Alignment for Pressurization Accuracy Checks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pressing apparatuses frequently suffer damage or deterioration due to high-pressure operations, leading to inconsistent product quality as operators struggle to ensure correct pressurization, which is not checked against reference values.
Innovation Solution
A pressing apparatus equipped with a storing unit for actual and reference data, an adjusting unit to align data patterns, and a determination unit to evaluate the similarity between actual and reference load data patterns, allowing for precise assessment of pressurization accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If pressing operation is performed in high pressure, then pressing force is improved, but reliability of driving devices deteriorates
Solution Approach 1:
The system implements feedback by measuring actual load data during pressing operations and comparing it against reference data patterns. The determination unit continuously monitors whether the actual load follows the expected pattern, providing feedback on the condition of driving devices. This enables early detection of deterioration before complete failure occurs, allowing maintenance to be performed proactively.
Solution Approach 2:
The patent replaces mechanical inspection methods with an automated data-based determination system. Instead of manually checking driving devices, the system uses load data patterns and automated comparison algorithms to assess device condition. This substitution of mechanical inspection with information-based assessment improves reliability monitoring capability.
2Productivity
If pressing operation is performed without checking against reference values, then productivity is improved, but manufacturing precision deteriorates
Solution Approach 1:
The system performs preliminary action by pre-storing reference data patterns that represent correct pressing operations. Before actual pressing operations, these reference patterns are established and saved in the storing unit. During operations, actual load data is automatically compared against these pre-prepared references, enabling quality verification without slowing down the pressing process.
Solution Approach 2:
The determination system performs self-service quality control by automatically comparing actual load data against reference patterns without requiring external inspection. The system independently determines whether pressing operations meet quality standards, eliminating the need for separate manual verification steps and maintaining high productivity while ensuring precision.

AI summary
A pressing apparatus that can check whether pressurization to products which are pressurization target of said pressing apparatus was performed correctly as the reference value or not is provided. A pressing apparatus 1 includes a storing unit 27 that stores a plurality of actual data which are load data which was actually measured and which are configured of a first information which indicates a position of a ram 9 or an operation time of the ram 9 and a second information which indicates a load of the ram 9 corresponding to the first information, and a plurality of reference data which is a reference for the load data, an adjusting unit 23 that expands and contracts the first information of at least one of an actual data pattern which is based on the plurality of the actual data stored in the storing unit 27 and an reference data pattern based on the plurality of the reference data stored in the storing unit 27 to correspond with each other, and a determination unit 24 that determines appropriateness of a load applied to the ram 9 in a pressing operation based on a similarity of the actual data pattern adjusted by the adjusting unit 23 and the reference data pattern adjusted by the adjusting unit 23.
