Universal Hydraulic Tensile/Bending Test Machine, Touch Screen

Universal Hydraulic Tensile/Bending Test Machine (600/1000 kN capacity) is designed to test the ferrous materials for structural values such as yield strength and tensile strength. Apart from tensile tests, Universal Test Machines can also be used for compression tests up to the capacity of the machine and Bending Tests on 8-40 mm diameter rebars. Bending apparatus and mandrels for Bending tests and Ball Seating Assembly for compression tests should be ordered separately.
 
To Test Core samples up to 100 mm upper platen must be ordered separately.

Maximum security is maintained on 600kN/1000 kN capacity Universal Test Machine by limit switch on the lower grip as well as the safety check valves on the hydraulic system. Hydraulic power unit works silently.

0-40 mm flat and 8-32 mm round samples can be tested on 600 kN capacity frame and 0-40 mm flat and 8-40 mm round samples can be tested on 1000 kN capacity frame with a user-friendly hydraulic jaws that comply with standards.

Load cell is used to measure stress. Strain measurement is done by the electronic displacement transducer built in the machine.

Tests can be done fully automatic by digital control unit or computer. Machine completes the test with the set pace rate and turns to start position automatically.

The distance between the grips can be set by motor driven handset system. The system is controlled by a hand up/down system. With open front hydraulic wedge grips user can load specimen easily.

HYDRAULIC GRIPS

Hydraulically operated grips, completely stop the possibility of sample sliding from the grips enabling for correct and definite strain measurements. Hydraulic grips are very safe and user friendly. The hydraulic grips has an independent hydraulic power unit with a working pressure of 400 bars.

600 kN capacity Machine is supplied with 8-32 mm round samples grip set and 1000 kN capacity Machine is supplied with 8-40 mm round samples grip set.

Jaw faces for flat samples should be ordered separately.

BENDING APPARATUS

Bending Apparatus is used for Bending Tests on 8-40 mm diameter rebars.

Can be chosen HR-B6000 & HR-B1000 Models Tensile-Bending Testing Machine for Ø 8-20 mm rebars.

The test piece is bent over a mandrel.

The angle of bend and the diameter of the mandrel should be selected in accordance with the relevant product standard.

The bend test is performed with a minimum angle of bend of 180° over a mandrel according to TS 708 and TS EN 10080 Standards.

After the test, it is checked whether there are any visible breaks or cracks on the test pieces.

Bending apparatus and mandrels for bend tests should be ordered separately.


HYDRAULIC POWER PACK AND H-TOUCH PRO MAX UNIVERSAL CONTROL UNIT

Hydraulic Power Pack

Automatic Hydraulic Power Pack, controlled by H-Touch Pro Max Universal Control Unit is designed to control the machine and processing of data from load-cells and displacement transducers which are fitted to the machine.

Very silent power pack can load the specimen between 2mm/min - 18mm/min with an accuracy of ±5%.  Safety valve (maximum pressure valve) is used to avoid machine overloading.
 
All the operations of Graphic Display are controlled from the front LCD display and function keys 2 analogue channels are provided for load-cells and displacement transducers.
 
It has easy to use menu options. It displays all menu option listings simultaneously, allowing the operator to access the required option in a seemless manner to activate the option or enter a numeric value to set the test parameters. Digital graphic display is able to draw real-time "Load vs. Time", or "Stress vs. Strain" graphics.
 
Automatic Hydraulic Power Pack has Dual Pumps.


Dual Pumps

The dual pumps are formed by two groups;

  1. Grip pump with dual stage pump
  2. Piston pump to make  tensile and compression tests
HİRA Test HR-B6000 & HR-B1000 tensile testing machine consist of two independent pumps working in one oil tank system.

One pump is controlled with digital readout unit with 3 phase controlled with and inverter to make test, other runs with a pedal to supply pressure to the grips. Grip pump has dual stage pump inside. On the dual stage pump, a high delivery, low pressure gear pump is used for rapid approach, for quick gripping the rebar while a low delivery, high pressure radial piston pump is used for 400 bar grip pressure.    

Two Motors
 
The motor which drives the main pump in an AC motor and it is controlled by motor inverter. The variation in the oil flow is executed with the variation of the rotation speed of the motor.
 
The motor which drives the grip pump in an AC motor and it is controlled by a manual pedal. The maximum pressure of the grips can be monitored by a 0-600 bar manometer fitted to the end of the pipe of upper and lower grip connection.  

Two Distribution Blocks

Two distribution blocks are used to control the oil flow direction supplied by the pumps, the following parts are fitted to the distribution block; Solenoid valve, Safety valve (max. pressure valve), Transducer and High pressure radial piston pump for main pump to make the test and Solenoid valve, Safety valve (max. pressure valve), low pressure gear pump and High pressure radial piston pump for grip pump.

Oil Tank

The tank includes enough oil to fill the mechanism which pushes the piston up during the test. The level and oil temperature can be seen on the indicator fitted to the tank. It has 60 L capacity. Hydraulic motor oil, number 46, must be used.
 

Digital Data Acquisition & Control System

HİRATEST H-Touch Pro Max Universal Control Unit is designed to control the machine and processing of data from the load cells or pressure transducers connected to the device in order to test the structural values of ferrous materials such as yield strength and tensile strength.

Software

HİRATEST H-GUI Software has been designed to test the structural values of ferrous materials such as yield strength and tensile strength with appropriate Hydraulic Universal Testing Machines and also with a computer.

The Hydraulic Universal Testing Machine can be controlled (Start, Stop commands) by a computer with the HİRATEST H-GUI Software free of charge.

This software provides data acquisition and management for compression, tensile and splitting tensile test throughout the test execution. The advanced functions for data base management provide an easy navigation of all saved data. The test results certificate includes all descriptive information. Therefore, test parameters can be set and details about the test carried out such as client details, test type, specimen type, user info and other information required can be entered and printed out as well as test report and graph.

Universal Test Software is developed for testing tensile strength of Reinforcing Rubbed Steel Bars and Welded fabric for the Reinforcement and Prestressing of Concrete. The software includes control of machine, data acquisition, saving them and preparing reports. The software accepts sample's weight, length, diameter and gauge length as input, and then the user can give start test command to the machine. The samples calculated diameter gives user a perspective about the density of rebar prior to the test. The software continuously updates load, stress and elongation percentage till the break point. The software is prepared as making at least 3 samples for each diameter. This gives user a total report about all the batch. The report includes all standard limits and one can easily check whether the sample can be acceptable. These limits are minimum yield, minimum tensile, minimum break elongation value, Tensile per yield ratio etc.
Software can be performed in Turkish and English.

Test results, graphics and properties of specimens can be saved in one folder. Old test folders can be reviewed and be edited easily.

User can highlight all 42 different specimen curves in different colors on the graphics.

Test parameters can be set and details about the test carried out such as Test Type, Sample Type, Report details, Customer details, Sample details and other information required can be entered in the software.

User can access any data of previously completed tests and use in his/ her new report since most of the tests have same structure and properties.

Each report is a group of 42 samples where 14 different diameters had been entered.

This informations and "Load vs. Time" or "Stress vs. Strain" graphics can be seen and printed out on the Test Report.
