High and low temperature tensile testing machine

1、 WDW-50 typeHigh and low temperature tensile testing machineProduct Overview

1. Main purpose and scope of application

This testing machine is suitable for mechanical property testing and research of metals, rubber, plastics, and other materials, and can be widely used in industries such as machinery, metallurgy, construction, transportation, aviation, aerospace, ships, ceramics, automobiles, pharmaceuticals, and electronics.

2. Performance characteristics

① Loading framework

a. The main frame includes a platform panel, a crossbeam, a moving beam, columns, and ball screws. All parts are made of steel, with a compact structure and firm connections, ensuring the rigidity of the testing machine and the smooth operation of the moving beam.

b. The testing machine is divided into upper and lower testing spaces. The upper space is used for tensile testing, while the lower space is used for compression and bending testing. This reduces the hassle of replacing testing aids for different tests and ensures the accuracy of the testing machine, making it easy to operate.

c. The experimental space is sufficient to meet various testing requirements to the maximum extent possible.

d. The protective cover of the rack ensures the cleanliness of the ball screw, and the limit device of the crossbeam can freely set the limit position of the moving beam up and down, ensuring the safe operation of the testing machine.

② Beam drive

The AC servo drive system controls the AC servo motor and drives the ball screw to rotate through a precision planetary reduction system, thereby moving the crossbeam up and down.

b. Adopting seamless circular arc synchronous belt linked with two lead screws, high efficiency, low noise, ball screw

Transmission loading, force value
