SERVOHYDRAULIC SINGLE SPACE TENSILE MACHINES, IB-MT4-MD2W SERIES

According to standards: ISO 7500-1, EN 10002-2, ASTM E4, DIN 51221, BS1610

For High load universal testing

These machines are designed for tensile and compression tests on metallic and non-metallic specimens.

Aditionally can be complemented with optional devices for bending, folding, shearing, etc.

Combined with IBERTEST MD Series control system and WINTEST software to assure the best performance in materials testing.

MODELS

GENERAL DESCRIPTION

The frame has a single test space, composed by a base plate, four over dimensioned columns and one upper closing crosshead. Manufactured according to Standards EN 10002-2; ASTM E4, ISO 7500-1; DIN 51221 and BS1610. A double-acting hydraulic actuator is mounted in the higher crosshead in line with the upper tensile gripping head. Over the base plate is mounted the lower tensile gripping head. Hydraulic gripping heads (upper and lower) with wedge closing system and independent opening/closing module for each head. Load measuring system by a full bridge strain gauge load cell, with temperature compensation. In the standard supply are included all the clamping jaws for the hydraulic gripping heads as well as one set of compression plates. Stroke transducer for controlling piston position, automatic return to starting position and stroke control (mm/min). After the test, the tensile gripping head returns to its initial fixed position to be ready for the next test, which is really useful for serial/repetitive tests. This advantage can be activated or not activated using our Win Test32 software. Hydraulic group housed in the metallic frame with closed loop control by manifold with servovalve. Electric cabinet mounted in the hydraulic group frame.

Only for pc controlled IBERTEST materials testing machines

Allows a direct links between the machine (any place with pone connection) and the Technical service of IBERTEST.

With this link the Post sale service of IBERTEST could easily diagnose and, most of times correct, the failures detected in the software without the need of a technical displacement.

Materials Testing Equipment

EUROTEST SERIES

According to standards: UNE-7-474-92, DIN-51221, 51223, 51227, 51228, BS-1610 and EN-10002-2

Third generation of electromechanical universal testing machines manufactured by IBERTEST.

MAIN SPECIFICATIONS
Wide range of models with maximum capacities: 50, 100, 200, 250, 300, 400, 500 and 600 kN.

Class 0.5 according ISO 7500-1.

Auto-scale from 1 to 100 % of maximum capacity.

Micro processed electronic, computer independent with USB 2.0 or Ethernet connection:

• Resolution: ± 180.000 real points per channel
• Maximum sampling frequency: 1 kHz or 5 kHz.
• Synchronous channels.
• Control close loop frequency: 1 milisecond (1 kHz) or 0.2 miliseconds (5 kHz).

Comfortable, high rigidity, over dimensioned testing frame. Allows high or low temperature test devices use, without modifications due to its wide testing frame.

Possibility of mounting additional load cells, with automatic recognition, calibration and cero setting. This performance allows an immediate adaptation of machines control to the load values of the load cell without human intervention. Avoids over loadings due to wrong configurations.

Close loop control over a brushless syncronich servomotor, basing on the displacement (mm/min) or sload (kN/sec) setting value.

Safety end of stroke of the mobile crosshead.

Mobile crosshead auto positioning, via software, to the initial position preset for serial tests.

Wide range of speeds with load or displacement control:

• Load: from 0,01 kN/s to 10% of maximum load/sec.
• Displacement: from 0,01 to 500,00 mm/min.

Displacement readout by means of encoder with 0,001mm resolution

GENERAL DESCRIPTION

EUROTEST TESTING FRAME

Developed for its use in Quality Control and Materials Testing Research Laboratories.

Applications: metals, plastics, composites, ropes, fabrics, paper, etc.

Mainly dened for carrying out tensile tests according with EN 10.002-1 and analogue standards as ASTM and ASME. With additional devices, compression, bending, folding, shear, punch, extrusion, etc tests can be performed according to several standards and over a large amount of materials.

High and low temperature tests can be carried out using thermal chambers, ovens or cooling systems.

TESTING FRAME ELEMENTS

Lower frame: mounted over it the lower testing device and inside it the mechanical transmission system of the screw drivers.

Machines with higher capacity than 200 kN, use two reducers (one per each screw driver), to increase the mechanical gain and assure the needed torque.

Frame covered by epoxy painted panels.

Base with auto leveling system with ball and socket joints. Allows direct placing of the machine over the laboratory floor, only being needed a resistant horizontal surface.

Two or four guiding columns and two high precision ball screw drivers with hard chromium coating, to assure an optimum load share and linear displacement of the mobile crosshead.

The mobile crosshead is displaced by the screw drivers and guided by the columns. The upper testing device,serial mounted with the load cell is placed under the crosshead.

The frame is closed with a superior crosshead to increase the rigidity.

Optional a secondary load cell could be mounted on the top crosshead, converting the machine in a double testing space one.
Mechanical transmission: two reducers (machines over 200kN) directly connected to screw drivers. The engine pulley system is connected to the reducers by means of a high resistance belt or chain.

LOAD MEASURING SYSTEM

Universal strain gauge load cell (tension compression), high precision and repeatability. Same capacity as the maximum load of the testing frame.

The quality of the load cells used, guarantees the 0,5 class according with ISO 7500-1 within the measuring range (1 to 100% of the nominal capacity).

The data obtained in the load cell is used for two applications: test results and to to allow the MD series control system to calculate the kN/sec load speed.

EPROM memory incorporated for safe calibration parameters saving. Even if the machines control fails, these data won’t be lost.

Additional load cells could be installed, to increase the load measuring capacity or for special applications. Anyhow, the 0.5 class is always assured.

DISPLACEMENT MEASURING SYSTEM

By means of a resolver which allows a 0,001 mm displacement resolution. The data obtained in the resolver is used for two applications: test results and to allow the MD series control system to calculate the mm/min crosshead displacement speed.
