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.
