Symmetric and asymmetric clamping

Hydraulic fixture originally used in more than 50 kN or test load, need to combine high clamping force (Fmax 10 kN to 2500 kN).-

  • Clamping pressure can be adjusted and high precision accuracy of repeat the pressure.
  • The rules applied to ensure the test force for sensitive material of the best effect.
  • ZwickRoell "constant clamping force to maintain" stable system reliably protect sample, avoid the closed because of the material flow in the process of fixture and clamping fixture deformation or the tensile or compressive force by don't want to influence.
  • Clamping force and the ratio of tensile force can adjust alone, make sure sample is holding it safely (at the time of maximum tensile force, about twice the holding force).

  • Hydraulic fixture is equipped with a set of eccentric piston, at the same time for long stroke, the piston can probe into the sample surface position and large opening size.
  • Clip on the below, sample clamp and the piston can also be holding a short sample.
  • Determine the test force of ensuring the applied for the sensitive material of the best effect.
  • Can accurately represent the contact pressure
  • Sample clamp can be in different frontal Angle (0 °, 45 ° and 90 °) assembled in the test system.
  • Located in the lower part of machine T - shaped groove in the service of T - shaped groove system installation, ensure that suitable for smaller force sensor, fixture and the installation of the test fixtures and bending tooling sample (in addition to the hydraulic clamp, model 8392, 10 kN Fmax).
  • Pyramid gripper (gripper with V - shaped groove) can be used by upper and lower exchange so as to achieve double service life.Used for round bar and flat specimen or is suitable for the different diameter of round bar (sandwiched face cross shape, V groove is suitable for the different diameter of the sample)
  • By remote control or PC, upper and lower fixture can be open or closed, or open and closed at the same time.
  • Clamping force and the ratio of tensile force can be individually adjusted, ensure the safety of the sample by holding it.(at the maximum tensile force, about twice the holding force).
  • The design of the hydraulic clamp provides the sample on the optimization of sample.
  • For manual on special sample, a set of adjustable, scale vertical clamping positioning for accurate sample.
  • In order to easier to sample, can use a center positioning block.
  • For safety reasons, the sample sample clamp can be used in.

The working principle of

According to the need of sample clamp closure pressure, oil pressure in the hydraulic unit setting, upper and lower control unit control sample clamp the respective closing and opening process,

Furthermore, when using a general-purpose hydraulic source unit, a closed process divided into stages of closing and clamping.In the closing stages, for safety reasons, the original keep sample in the upper clamp, in the process of clamping, will exert all holding force, the clamping force is based on the tensile force of hope.

Double-sided horizontal pushing actuating cylinder

All hydraulic fixture on both sides are equipped with actuating cylinder, which means that the sample clamp using hydraulic open, rather than use spring reset.Can adjust the closing and opening pressure.

Compared with single horizontal pushing actuating cylinder, single flat push by mechanical spring return, double-sided horizontal pushing actuator cylinder to ensure the safety of the sample clamp open.If the sample is curved or difficult to clamping, also can use double horizontal sliding clamping.In addition, in does not need to fully open the actuator cylinder stroke, can press the stop button will clamp open break to the position of the desired.According to the specimen thickness, adjust the opening stroke, for special thin specimen, reduce the testing time, and reduce the risk of the tester was sandwiched.

One horizontal pushing and double horizontal pushing sample clamp

Was a moving cylinder hydraulic fixture can be used for symmetric and asymmetric sample clamping (shear test, for example).Threaded unit set up the clamping and need the opening width of the specimen thickness.

Was a moving cylinder of the hydraulic clamp series cylinder can also be evenly applied test force to the sample (especially suitable for fabrics, textiles and geotextiles test).

Double actuator cylinder hydraulic fixture always symmetric closed, its center and the tensile axis coincidence, this means that the sample in the axis position accurately clamping, therefore does not need to adjust the thickness.

T-slot system

T - shaped groove system enables fast small force value of force sensor installation, fixture, test fixtures and fixed tooling sample, without the need for frequent disassembly sample clamp.

T - shaped groove is processed in the region of the sample fixture clamping, these accessories can be installed in the T - shaped groove T - shaped groove here locked tight relative to the installation of other tools and fixtures, T - shaped groove can be installed and other test equipment to save time.
