Pole lug tensile tester

Pole lug tensile tester

The pole ear tensile testing machine is mainly used for testing and analyzing the mechanical properties of metal and non-metallic materials (including composite materials) adhesives, adhesive tapes, stickers, medical adhesives, protective films, release papers, composite films, plastic packaging for food bags, plastic packaging for daily cosmetics, artificial leather, woven bags, films, paper sheets, such as tension, compression, bending, puncture, peeling, tearing, etc., with stress, strain Three closed-loop control modes of displacement can be used to calculate parameters such as force, tensile strength, bending strength, compression strength, elastic modulus, elongation at break, yield strength, etc.

CMT2502 pole lug tensile testing machine is mainly used to test and provide test data according to GB, ISO, JIS, ASTM, DIN, EN and other standards. It is an electromechanical integration product, mainly composed of mainframe (including frame, base and transmission system), fixture, deformation measurement system, software system and electrical system.

The CMT2502 host adopts a single-space structure, and the test space is in the lower space, which is mainly composed of a base and a frame.

1.Host frame

The upper crossbeam and worktable are fixed with high-strength light bars to form a high rigidity frame structure; The high-precision ball screw without clearance is adopted to improve the transmission efficiency and displacement accuracy; The coaxiality of the testing machine is good (<8%). The upper, middle and lower beams are made of QT600-3 ductile iron with tensile strength of 60k (600MPa) and yield strength of 40k (400Mpa). The corrosion resistance and oxidation resistance of ductile iron are better than that of cast steel. Due to the microstructure of nodular graphite of ductile iron, it is better than cast steel in reducing vibration energy, so it is more conducive to reducing stress.

2.Fixture

Standard fixtures of various materials are easy to operate and reliable to hold. They can be configured with pneumatic and hydraulic wedge-shaped fixtures and horizontal push hydraulic fixtures to greatly improve the working efficiency. The clamping force can be adjusted to meet the test requirements of different materials of users, and can also be customized according to customer needs；

3.CMT3200 servo control system

Real-time and dynamic display of test process and test curve, data processing through modular software, data re-analysis and editing of curve amplification, output of test reports and curve patterns in different formats, and support networking for data transmission.

4.Deformation measuring system

Various electronic extensometers can be equipped according to different materials and specifications, and digital large deformation measuring system (measuring system with wide deformation measuring range, high accuracy and fast response) can also be equipped to realize height measurement of large deformation materials such as rubber and plastic.

5.Force-measuring sensor

Adopt imported strain gauge load sensor with high stability and precision; The precision measurement system with high stability has the same resolution throughout the whole process, ensuring that the error of the test force indication is not more than ± 0.5%. Multiple load sensors can be used according to different ways to achieve multi-range test force range measurement; Good temperature compensation, high sensitivity, high rigidity and good long-term stability.

7.Control drive system

The fully digital imported AC servo motor and AC servo motor with high control accuracy and high response frequency are adopted. The transmission system has high efficiency, low noise, balanced transmission, and the allowable speed error is not more than ± 0.2%. The test speed range can reach 0.001~1000mm/min stepless speed change. The circular arc tooth synchronous belt drive has the advantages of high transmission accuracy, transmission efficiency of 98%, more stable transmission and low noise.

8.Safe and humanized design

The emergency stop control switch can reliably lock the equipment in case of emergency, and has multiple protection functions such as over-current, over-voltage, under-voltage of the drive system, overload of the whole machine, breaking and stopping, and position limit of the moving beam. When the overload is 10%, the machine will stop automatically, the moving beam displacement speed drive system will stop automatically when the overcurrent occurs, and the upper and lower limit positions of the beam displacement will stop automatically; Manual and automatic return function of beam, multiple protection of software and hardware, and safety of equipment and personnel.
