WDW-2E

1、 Product Name: Microcomputer Controlled Electronic Universal Testing Machine

2、 Product functions and features:

The WDW-2E machine is a new generation of microcomputer controlled electronic universal testing machine. Mainly used for testing mechanical performance indicators such as tension, compression, bending, shear, peeling, and tearing of various metal, non-metal, and composite materials. The system adopts microcomputer closed-loop control, which has a wide and accurate loading speed and force measurement range, and has high accuracy and sensitivity in measuring and controlling loads and displacements. This equipment is suitable for manufacturing industries such as metals, adhesives, pipes, profiles, aerospace, petrochemicals, waterproofing membranes, wires and cables, textiles, fibers, rubber, ceramics, food, pharmaceutical packaging, geotextiles, films, wood, paper, as well as product quality supervision departments at all levels. It is also suitable for teaching demonstrations in colleges and universities.

The design of the testing machine host has the characteristics of beautiful appearance, easy operation, stable and reliable performance, no pollution, low noise, and high efficiency. The design of auxiliary equipment is matched with the host, and various fixtures are configured according to different testing requirements. Convenient, reliable, and non slip clamping.

3、 Product Structure and Performance:

◆ Host structure:

The host consists of an upper crossbeam, a moving crossbeam, and a worktable connected by columns and ball screws to form a rigid frame structure. The Panasonic AC servo motor and AC servo speed control system are installed under the worktable. The AC servo motor drives the ball screw to rotate through a synchronous toothed belt reduction mechanism, thereby driving the moving crossbeam to move up and down to achieve loading tests such as tensile and compressive testing of the specimen.

◆ System composition:

The measurement and automatic control system consists of high-precision sensors, high-precision electronic extensometers, servo motors, dedicated independent controllers, dedicated measurement and control software, and Lenovo mainstream brand microcomputers.
