I. Basic Composition of the Proposal

This technical proposal is based on our company's years of research into online Hardness Testing technology for gas cylinders and the accumulated experience from delivering numerous online hardness Testing devices to domestic and international customers. It is designed in accordance with the basic requirements of gas cylinder production lines, following extensive market research and industry exchanges. Given the differences in your production site, detailed technical discussions are necessary to ensure clear and precise technical specifications, smooth production Testing lines, and consistent workflow rhythms.

The basic components of this technical proposal are:

1、The Online Brinell Hardness Tester is embedded into the existing production line, becoming an integral part of the workflow.

2、The Online Brinell Hardness Tester, Input Roller Conveyor (provided by the buyer), and Output Roller Conveyor (provided by the buyer) are interconnected for synchronized control but can also operate independently.

3、The Online Brinell Hardness Tester is designed in compliance with the Brinell Hardness Test Method, meeting the requirements of GB/T 231.1-2018 and GB/T 231.2-2012.The equipment complies with GB/T 5099-2017, GB/T 11640-2021, ISO 9809, TSG 07-2019 (Special Equipment Production and Filling Licensing Rules), and TSG 23-2021 (Gas Cylinder Safety Technical Regulations). It is suitable for online hardness testing of gas cylinders, specifically for Brinell hardness testing of cylinder bodies after heat treatment.

II. Key Features

This technical proposal adopts a dual-stable direct-drive hardness tester with a loading/unloading unit and an integrated spindle to ensure precise application and removal of test forces. Industrial computers, PLCs, and multiple sensors automate the entire online process, enabling unattended operation and fully automated hardness measurement.

●Robust gantry frame structure: High rigidity, suitable for hardness testing in production environments.

●Precise workpiece positioning: Ensures accurate alignment of test points.

●Automatic clamping: Eliminates the impact of vibrations on hardness testing.

●Dedicated hardness test head: Features fully automated closed-loop force control for stable and reliable test forces.

●CCD indentation auto-capture system: Automatically measures indentations with high precision, eliminating manual measurement.

● Pre-set hardness limits: Automatically judges whether test points are qualified and provides audible/visual alarms.

● Pre-set test conditions: Includes material, workpiece name, model, test date, operator, etc.

● Automatic data storage: Test data is saved to a database for traceability.

● Compliance: Meets the accuracy requirements of GB/T 231.2-2012 and ISO 6506-2, as well as GB/T 5099-2017, ISO 9809, GB/T 11640-2021, TSG 07-2019, and TSG 23-2021.
