Dual Space Electro-hydraulic Servo Universal Testing Machine

DHDC series computer control servo-hydraulic testing machine is suitable for testing tension, compression, bending and shearing strength of various metallic & non- metallic materials. Equipped with the electronics, computer &software packages, the servo-hydraulic tester of dual space is capable of controlling the test procedures by the predetermined programs. The computer control servo-hydraulic testing machine can also display, record, process and print the test results. The test curves can be drawn automatically in real time. The servo-hydraulic testing machine is easy to operate and is versatile in the applications of metallurgy industries such as steel mills & alloy, reinforced bar, aircraft manufacturer, research institutes, laboratories, calibration institutes etc.

Applied Standard

1. Load meets or exceeds the following standards: ASTM E4. IS07500-1, EN 10002-2, BS1610, DIN 51221.

2. Strain measurement meets or exceeds the following standards: ASTM E83, ISO 9513, BS 3846 and EN 10002-4.

3. Safety: The computer control servo-hydraulic universal testing machine shall conform to all relevant European CE Health and Safety Directives EN 50081-1, 580081-1, 73/23/EEC, EN 61010-1

4. Tensile test at room temperature: DIN EN 10002-1, ISO 6892, ASTM A370, ASTM E 8

Load Frame Structure
Featuring a dual test space with high stiffness to meet extensive test applications, test loads are available from 600kN to 3000kN.
1. Compact design with rigid four-column & two-lead screw construction.
2. Dual work-space design. The upper one is for tension test (expandable for peel & tear test etc) while the lower one is for compression, bending and shearing tests, which is quite convenient for different kinds of tests.
3. The frames have considered all of the human factor into the design to ensure safety, improve testing efficiency, and reduce operators’ weariness.
4. Cylinder mounted at the bottom of the machine guarantees the working gravity.
5. Test space can be extended according to the length & elongation of specimen and other related test requirements.

Crosshead
The design of front open hydraulic wedge grips makes the exchange of inserts and specimen loading easier. Tensile grips are embedded into upper fixed and lower movable crosshead to keep maximum strength. Lower movable crosshead motor-driven by roller chain make the operation much easier.

Hydraulic power pack of servo-hydraulic Testing Machine
1. Variable pressure hydraulic power supply provides pressure on demand, reducing heat, extending oil life and eliminating the need for water cooling.
2. Double control mode, manual control & PC servo control model. For manual control model, hydraulic pack is for manually loading and clamping specimen hydraulically for high efficiency of test. While test data & curves can displayed on PC, manual control mode is especially suitable for the batch broken load tests on the large scale of specimens. For PC servo control mode, all can be controlled & processed by PC automatically. Closed-loop servo control of position, load, stress & strain increases the test efficiency and meets the data consistency between collection and analysis.
3. The pumping units are designed to be located in the lab with lower noise level within 65dBa.

Jaws, Fixtures, Locks, Chin Adapter Surfaces, Couplings and Adapters
Jaws, Fixtures, Locks, Chin Adapter Surfaces, Couplings and Adapters are in compliance with the standards and the design and production belong to our firm.
All capacities are manufactured in accordance with the requirements.
During the design phase, the production is made to provide the user with the most comfortable testing facilities.

Wedge Grips
The pendant jaws provide a high clamping force advantage during application. The clamping force is transmitted to the sample through the shaft or jaws with a shaft. The main clamping force is first formed by the wedge effect during the pulling operation. This jaw type has two advantages: The sliding features are firmly attached at the beginning of the application;

Test Apparatus for Bending Tests
Tilt Tests are one of the most common applications. Bearing radius, condition and sample thickness are important factors in these tests. The parameters of the Bending Tests are generally determined by 3 Point or 4 Point Bending Tests.
• Testform offers the customer a specially configured bending apparatus or complex bending test systems that meet different test norms.
• We offer special tilt test systems for your industry and test applications.
• Thanks to the easy use of bending test systems, very different samples can be tested quickly and accurately.
• The freely adjustable bearing case allows testing of samples of different lengths and makes your testing system versatile.

Testing Apparatus for Compression Tests
In compression tests, the specimen is repressed until it breaks, cracks or crushes to a certain degree. In order to perform an efficient test, the sample must be placed properly on the platen. Determinant factors; The size, shape, surface, material and surface roughness of the stamping plates.
• Testform, as well as different stamping plates; The customer also offers special plates.
• In addition to our product program, complex printing test systems; The customer also offers special combinations or products in perfect compatibility with different samples, materials and parts tests.
• Central gravure option facilitates sample positioning.
• In cases where the sample is requested to conform during the test, the stamping plates can be rigidly or arbitrarily connected with a circular element.
