In terms of tension, compression, bending, cutting, peeling, tearing, and other tests, the electronic universal testing machine is primarily suitable for testing metal and non-metallic materials. These materials include rubber, plastic, wires and cables, fiber optic cables, safety belts, belt composite materials, plastic profiles, waterproof rolls, steel pipes, copper profiles, spring steel, bearing steel, stainless steel (including high hardness steel), castings, steel plates, steel strips, and non-ferrous metal wires. Additionally, the machine is able to perform tests such as two-point extension, which requires the use of an extensometer. An electromechanical integrated design is utilized for this machine, which is mostly made up of force sensors, transmitters, microprocessors, load drive mechanisms, computers, and color inkjet printers. It offers a high level of accuracy and sensitivity when it comes to measuring and managing loads and displacements, as well as a wide and accurate range for measuring loading speed and force. Additionally, it is able to carry out tests involving automatic control which involve constant loading and constant displacement. For the floor-standing model, the styling, and the painting, all of the relevant concepts of ergonomics and contemporary industrial design have been taken into consideration.
June 2007 marked the beginning of operations for Dongguan Hongjin Testing Instrument Co., Ltd. Specifically, it is a high-tech manufacturing company that specializes in the design and automatic control of large-scale non-standard testing equipment. Some examples of this equipment include simulated environmental testing, material mechanics testing, optical dimension measurement, vibration impact stress testing, new energy physics testing, product sealing testing, and many more! At the same time as we adhere to the corporate idea of "quality first, honesty first, committed to innovation, and sincere service," we also adhere to the quality principle of "striving for excellence." We serve our clients with the highest devotion.
In tensile testing equipment, fixtures are an essential component that cannot be overlooked. Tensile testing machines make use of fixtures to hold specimens, as well as force application devices, force value display devices, and recording devices, in order to establish whether or not materials are certified and meet preset performance indicators. Because there are no fixtures available, it is impossible to determine these. When the material sample undergoes changes, the fixture, which is a component of the tensile testing equipment, undergoes repeated adjustments to accommodate these changes. This is because different materials call for different fixtures, and the fixture is a significant component in determining whether or not the test can be carried out without any problems and whether or not the results of the test are accurate. The particularity of the fixture structure is established as a result of the fact that the tensile testing machine is able to test the performance of a wide variety of items, as well as the diverse structures and appearances of a wide variety of specimens. As a result, the utilization of the fixture in a manner that is both logical and proper is beneficial to the smooth progression of the test.
1. The correct clamping of the sample is crucial for the test, as it directly affects the success or failure of the test and the accuracy of the test data;
2. For rectangular and brittle specimens, clamping is more important;
3. When clamping, try to install the sample in parallel as much as possible before stretching it;
4. In steel wire winding fixtures, there should be no wire compression, as this can cause local pressure concentration and often lead to breakage at the compression point, resulting in poor breakpoints;
5. For wedge-shaped fixtures, the left and right alignment of the specimen is ensured by the fixture, but it is prone to tilting before and after installation. During the stretching process after tilting, the force on both sides of the specimen is uneven, which may tear the specimen or result in poor breakpoints;
6.For overlapping specimens, the overlapping surface should pass through the force center of the sensor.
1.Before starting the testing machine, it is necessary to check the position of the limit knob to ensure that it meets the requirements of the test stroke and does not cause collisions between the upper and lower fixtures. The limit switch installed on the middle crossbeam moves together with the middle crossbeam.
2.When placing the specimen, it is necessary to place it at least two-thirds of the length of the jaws in order to effectively grip and protect the jaws.
3. When clamping the extensometer, pay attention to placing adjustment shims and handle them gently to protect the extensometer blade. Do not pull the wires.
4.During the experiment, pay attention to immediately remove the extensometer according to the software prompts to prevent it from being damaged by excessive deformation or sample fracture.
