Product Details
1. Structure, Performance, Features
The testing machine mainly consists of a horizontal main machine, hydraulic station, electrical control console, and computer control system.
1. Horizontal Main Machine:
The main body of the testing machine adopts a frame horizontal structure:
The hydraulic servo cylinder is installed on the right side of the frame's cylinder seat, and the piston end is directly connected to the moving crossbeam through a universal ball joint and a force sensor. The moving crossbeam is connected to the front fixture seat through two lead screws for tensile loading.
The movable rear fixture seat can be adjusted left and right along the frame with manual assistance. When it reaches the specified point, the manual assistance pin mechanism uses a pin to fix the rear fixture seat on the left and right frames, thus achieving the adjustment of the distance of the rear fixture seat, with a longitudinal pin spacing of 0.5 meters. The front and rear pulling heads are connected to the sample using a U-shaped manual pin method. Under the action of hydraulic power, the cylinder piston extends to push the crossbeam and the fixture seat, thus conducting loading tests on cable and other long rope samples.
A displacement measurement device is installed on the side of the hydraulic cylinder to measure the stroke of the cylinder, which can approximate the deformation of the sample. A movable protective net is installed on top of the main machine to provide protection during the breaking test.
2. Hydraulic Station
This part is the loading power source of the testing machine, mainly consisting of hydraulic pump unit, proportional valve, electromagnetic reversing valve, pressure adjustment valve, hydraulic oil tank, and hydraulic accessories. The working principle is as follows:
At the start of the test, the lead screw motor starts, pre-tensioning the sample through the lead screw, quickly tightening the sample, and then entering the automatic control loading state. The microcomputer controls the electro-hydraulic servo valve, driving the servo cylinder to complete the entire test process according to the program.
3. Functions and Features of the Computer and Electrical Control System:
3.1 Using a branded microcomputer, the dedicated testing machine software can automatically control the test force and displacement in various modes according to national standards, completing the setting of test parameters, control of the test process, data collection, processing, analysis, and display, accurately achieving constant speed displacement control and constant speed test force control.
3.2 The screen display function for test force, peak value, sample deformation, piston displacement, and test curve, with full keyboard input operation and intelligent setting of control modes, achieves smooth switching between various control methods, providing maximum flexibility to the system.
3.3 Comprehensive test curve graphic processing function: The curve can automatically track and adjust during the test process, can print and save curves, can be zoomed in locally or full screen, and can track curves for browsing and observing data.
3.4 Powerful report processing function: Reports can be printed, saved, and previewed, with data automatically filled into reports. Users can customize report formats according to requirements, which is convenient and intuitive, a feature not available in general testing machine software.
3.5 Comprehensive protection measures: The hydraulic and electrical parts have protection measures against overpressure, overcurrent, etc., and the software has overload protection for test force, displacement, deformation, etc., to prevent damage to the equipment.
