The Computerized Sofa Comprehensive Testing Machine is a specialized equipment designed to evaluate the mechanical properties of sofas, with a primary focus on testing the durability of critical components such as seats, backs, and armrests. By simulating real-world usage scenarios, this machine applies repeated loads to these areas using loading modules of specific shapes and masses, following set load forms and frequencies. This process effectively assesses the sofa’s ability to withstand long-term repetitive use, ensuring it meets quality standards and user expectations.
One of the key advantages of this testing machine is its ability to automate various measurements, including seat height, compression values (a, b, and c), and the offset of the backrest and armrests. This eliminates the high errors associated with manual measurements and significantly saves working time, streamlining the quality control process for manufacturers.
In terms of compliance, the machine adheres to the standard QB/T1952.1-2012, ensuring that the testing procedures and results are aligned with industry regulations, providing reliable data for product certification and improvement.
The product is equipped with a range of notable features:
Advanced Control Mode: It is computer-controlled, enabling automatic force control. When a specimen is damaged, the machine automatically releases pressure, returns the cylinder to its original position, and displays the force value and sub-values. It also stops and returns automatically once the set number of tests is reached, with a high-precision displacement meter for automatic ranging.
Fully Automatic Operation: With one-key automatic operation, once the specimen is placed, pressing the “execute” key initiates the test process, which runs automatically according to the set procedure, reducing manual intervention.
Comprehensive Safety Devices: These include settings for maximum capacity and displacement, automatic detection of circuit switches with leakage protection, breakpoint stop functionality, and upper and lower limit fretting devices, ensuring safe operation.
Versatile Control Module: Allows users to set load, test times, duration, failure tests, test dates, and intermittent periods, catering to various testing requirements.
Technical parameters of the machine further highlight its capabilities:
The force sensor has a measuring range of 2000N and a resolution of 1/10000, with a system force measurement accuracy of ±1% for static forces and 0-5% for dynamic forces.
The figure 8 model, used in testing, weighs 50±0.5kg.
Specific loading forces are set for different parts: 250N for armrests and 300N for backrests.
Test speed can be adjusted from 5 to 30 times per minute.
It can accommodate specimens with a maximum size of 220x130x60cm (LxWxH), with the maximum width of the handrail adjustable between 500-900mm.
Displacement measurement covers 300mm.
The control system features a 19-inch LCD display, and data is automatically stored in a main computer, which is equipped with the display and a printer.
Reports can be automatically generated in Word, Excel, or PDF formats as required by customers.
Driven by an imported motor, it allows for arbitrary setting of force values and displacement, and operates on an independently developed system.
In conclusion, the Computerized Sofa Comprehensive Testing Machine plays a vital role in the sofa manufacturing industry. By combining precise control, automation, and compliance with industry standards, it ensures that sofas are durable, reliable, and able to withstand the rigors of daily use. For manufacturers aiming to deliver high-quality products, this machine is an essential tool for quality assurance and continuous improvement.
