Technical introduction of double clamping scheme for 30 ton microcomputer-controlled electronic universal testing machine

In the testing of mechanical properties of materials, the 30-ton (300kN) microcomputer-controlled electronic universal testing machine is widely used in scientific research institutes, industrial quality inspection and third-party testing fields. According to different test conditions and use requirements, the same gantry host can adapt to two clamping structures, manual clamping and hydraulic clamping. The two configurations have the same host architecture, and the core difference lies in the clamping mode, use efficiency and applicable scenarios, which can meet the detection needs of different users.
I. Manual clamping configuration
This model adopts the mechanical wedge locking structure of handwheel, and the sample is fixed by manual operation. The equipment structure is simple and there is no hydraulic oil circuit system, which can effectively avoid the oil circuit leakage problem. The equipment operation threshold is low, the later maintenance is simple, and the operation and maintenance cost is controllable.
This configuration is suitable for scientific research laboratories in colleges and universities, regular incoming material quality inspection in enterprises and other scenes, and it is suitable for the inspection work with moderate test frequency and moderate tensile load, and can stably complete the mechanical tests of conventional samples such as metal bars, plates, plastics and composite materials.
Under the condition of mass inspection, repeated manual locking operation will reduce the test efficiency. For ultra-high strength samples, if the clamping operation is not standardized, the sample may slip slightly, which is more suitable for routine and small and medium-sized batch tests.
Second, the hydraulic clamping configuration
The hydraulic clamping machine is equipped with automatic hydraulic clamping system, which has uniform clamping force and stable output, and can realize automatic locking operation, greatly simplify the manual operation process, and the test is labor-saving and convenient. The equipment has excellent clamping stability, which can effectively guarantee the clamping effect for high-strength thick plates and high-tensile metal samples, and is suitable for long-term and continuous batch inspection.
Compared with the manual clamping model, the hydraulic clamping system is more complicated in structure, and the overall configuration cost of the equipment is relatively higher. At the same time, it is necessary to carry out regular oil inspection and routine maintenance to ensure the stable operation of the equipment.
This model is mostly used in third-party testing institutions and quality inspection departments of heavy industry enterprises, and it is suitable for professional testing scenes with large daily average testing volume, high testing frequency and strict requirements on testing stability and data accuracy.
III. General Core Performance of Equipment
The main machine performance of the two clamping devices is consistent, and the core parameters and functions are stable and unified:
The equipment adopts high-rigidity portal frame, which has good anti-eccentric load performance, can ensure the stable output of 30 tons of force and the stable operation accuracy of the equipment;
Equipped with servo drive system, the force value and displacement data are collected accurately, and the complete test curve can be generated in real time, with strong data traceability;
Modular tooling design is adopted, and auxiliary tooling such as bending, compression, shearing and peeling can be selected as required to realize multi-purpose of one machine and adapt to various mechanical testing items;
Supporting professional measurement and control software, it can automatically measure core mechanical indexes such as tensile strength, yield strength and elongation after breaking, support one-click export of test reports, and be compatible with mainstream domestic and foreign test standards such as GB, ISO and ASTM.
The equipment can test the mechanical properties of steel, aluminum alloy, carbon fiber composite and various non-metallic materials, such as tension, compression, bending and tearing, to meet the requirements of material testing in many industries.
Iv. Description of Selection for Working Condition Adaptation
In order to meet the actual use needs of different users, the adaptation scheme is combed according to the equipment characteristics:
Users with conventional test scenarios, universal sample types and low test frequency can choose manual clamping configuration, which makes the equipment practical and cost-effective.
Users with high-strength material testing, large-scale continuous testing and high requirements for testing stability can choose hydraulic clamping configuration to ensure test efficiency and testing accuracy.
