1000KN Hydraulic Universal Tensile Testing Machine

Description 

This product is the ideal high-quality testing equipment for scientific research institutions, universities and colleges, metallurgy, machinery manufacturing, boiler vessels and aerospace enterprises and institutions. The series of models use hydraulic loading, easy to operate, stable performance, safe and reliable. The test operation and data processing are in accordance with GB/T228.1-2010 "Room Temperature Tensile Test Methods for Metal Materials", and can be used for experiments according to GB, ASTM, DIN, ISO, JIS, BS and other standards.

Mechanical process structure 

1. The mainframe of the testing machine adopts the cylinder down structure, the tensile space is located above the mainframe, compression, bending, shear and other test space is located below the mainframe between the middle beam and the table, through the movement of the middle beam to adjust the test space, the table and the cylinder using hard contact, medium pressure balance piston, the piston is always in the center of the cylinder, reduce the friction between the cylinder and the piston, so that the experimental accuracy is higher, the force value is more accurate. Overcome the traditional process of spherical contact between table and piston, theoretically oriented. Thus ensure the stability of the mechanical properties of the product.

2. The structural parts of the main machine are made of cast steel parts after heat treatment and precision machining, and the columns and transmission parts are made of high performance alloy structural steel, which are strictly inspected and finely assembled, so that the whole machine is not only strong in overall rigidity but also good in stability. The main and auxiliary oil cylinders are sealed by gapless oil film, no oil leakage, and the center compound oil cylinder is used at the jaws for direct push clamping, which overcomes the shortcomings of easy sliding and easy deformation of the pallet liner clamping block set structure, and the loading and unloading is very convenient and durable.

Control and measurement system

1.the machine uses a full digital closed-loop control system for control and measurement, and through the computer for the test process and test curve dynamic display, and data processing, after the test can be enlarged through the graphics processing module for data re-analysis and editing, to meet the provisions of many countries on the metal tensile test of the various standard tests, but also in accordance with industry standards to achieve the tensile, compression, bending, shear and other types of different materials or products, Compression, bending, shear and other types of tests, control system with force control, deformation control, displacement control three control modes, in the test process, the three control modes can be smoothly switched in accordance with the set program.

2.the software can automatically obtain ReH (upper yield strength), ReL (lower yield strength), Rp0.2 (specified non-proportional extension strength), Rt0.5 (specified total extension strength), Rm (tensile strength), E (modulus of elasticity) and more than 20 required test data. It can also achieve equal-rate force loading, equal-rate deformation, equal-rate displacement and other test requirements;

3.Accurate and perfect data analysis function, using human-computer interaction to analyze and calculate the test

The mechanical performance index of the material can also be manually intervened in the analysis process to improve the accuracy of the analysis;

4.The test data is managed by database, and all test data and curves are automatically saved.

5.realize special closed-loop control of displacement, deformation, force and speed, and during the test, it can flexibly

change the test speed and test curve in order to make the test program more flexible and fast;

6.multi-layer protection: with software and hardware two-level protection function, can realize the overload of the testing machine

Over-current, over-voltage, under-voltage, over-speed, limit and other safety protection methods;

7.test software reserved for a number of open program interface, the user can write their own custom special test methods, the default implementation of GB, ISO and other test standards; reserved for open data interface transmission network port, easy for the user to upload the network data later, as well as software upgrades.
