horizontal tensile test machine

Model: LDW, Electronic, computer control

Electronic horizontal tensile test machine can be used for tensile testing of various metal materials, steel wires, power fittings, chains, lifting belts, electric wires and cables, and other relatively long specimens. It can perform tests and research on electric wires and cables under increasing tensile stress, breaking tensile force, breaking strength, and elongation, as well as measure rated breaking force (RTS), maximum allowable tension (MAT), 20% RTS, 40% RTS, 60% RTS, and 2%~100% RTS; OPGW tensile performance; stress-strain properties of electric wires and cables; and creep performance of electric wires and cables over 1000 hours. It is widely used in metal products, construction structures, ships, military industry, and other fields. The microcomputer-controlled electronic horizontal tensile testing machine adopts our company's mature universal testing machine technology and incorporates a steel frame structure to convert a vertical test into a horizontal one. This increases the tensile space (which can be extended to over twenty meters, something a vertical test cannot achieve), meeting the requirements for testing large or full-size specimens.

General introduction

This testing machine uses an integrated steel plate welded frame structure. It is driven by an AC servo motor connected to a ball screw, with a load sensor measuring the force. The tensile space can be adjusted in stages according to the specimen's length. The computer screen displays the test force and test curve, and the test data is automatically processed according to the test method requirements. This machine is an ideal inspection device for coal and electricity enterprises, coal mining machinery, safety production inspection institutes, and technical supervision agencies. It is suitable for tensile load and failure tests of products such as electrical wires and cables, porcelain insulators, double hooks, steel strands, safety belts, waist ropes, and foot straps, requiring flexible and convenient operation, slow and stable loading, and strong machine bearing capacity.

The main machine of the testing machine is designed to be aesthetically pleasing, easy to operate, and has stable and reliable performance, with no pollution, low noise, and high efficiency. The auxiliary tools are designed to match the main machine, featuring a wedge-type sliding structure with manual or automatic rotational clamping, so that the specimen is unaffected by additional forces. Clamping is convenient, reliable, and slip-free.

1. Uses an AC servo motor and AC servo speed control system to manage the testing process, greatly improving control accuracy and quality. It operates smoothly, efficiently, and quietly (virtually silent at low speed) with a greatly expanded speed range. This is beneficial for low-speed testing of conventional materials (metals, cement, concrete, etc.) as well as high-speed testing of non-metallic materials (rubber, plastics, etc.). It can also be used for quickly adjusting the test space when idle, saving auxiliary testing time. The test speeds meet the requirements for all conventional metal and non-metal material tests currently in China.
2. The reduction mechanism is composed of a synchronous toothed belt and a precision ball screw pair for a "strong-to-strong" connection, making the structure simpler and more streamlined, significantly improving transmission efficiency.
