Socket Style

Socket Style Torsion Grips

These socket style adapters allow the connection of any 0.5 inch drive socket or accessory directly to the torque cell and/or output shaft on the MT series frames. Smaller drive sockets can be connected through the use of reducing adapters.

English and Metric sockets sets are available in a large range of sizes that allow the testing of fasteners or finished products that have a hex type connection. These adapters are useful for testing the running torque of locking and non-locking fasteners, proof testing of fasteners with torsional loading, or checking the torsional resistance of ratchet, torque wrench, or other type of tool.

Principe de fonctionnement

The Socket Style grip adapters are threaded into or bolted to the output shaft and/or torque cell on the MT series frames. A jam nut is used to fix the threaded adapter in place and maintain it tight for bi-directional testing.

The socket is then pressed onto the adapter and is retained by a spring loaded ball just like any commercial ratchet. Two sockets can be used for testing bolt and nut specimens, or just one socket can be used to tighten or loosen fasteners in parts that must be held in a custom fixture.

Mechanical Wedge Lever Action Grips

Mechanical Wedge Action Grips (Lever Operated)

T-Grip Holders are available in load capacities from 22.2 to 150 kN (5,000 to 33,750 lbf.) These economical and versatile assemblies are designed for simplified specimen insertion and removal, a feature that saves time and reduces operator fatigue, increasing productivity in repetitive testing operations.

Engineered to be adaptable to both hydraulic and electromechanical UTM's, most T-Grip Jaw Holders are available with an open front style that assists with simple insertion and removal of test specimens. 

An assortment of interchangeable jaws will fit in the T-Grip holders, which allows for the acceptance of a range of sizes in both flat and round specimens. To increase the ease of operation, the locking mechanism of the lower holder keeps the grip jaws open so that one-handed specimen insertion is possible. 

The upper and lower grip bodies are structurally the same. Each grip body has a pocket that holds a pair of grip jaws and utilizes a wedge design. This wedge design causes the grips to further tighten as load on the specimen is applied, reducing occurrences of slippage.

Principe de fonctionnement

T-Grip Holders are available with two types of actuation, lever/spring or screw type.

All capacities of T-Grips are offered with lever/spring actuation, which uses a lever to raise and lower the jaws in the grip pocket and a spring to provide the initial clamping force on the specimen. When loading a specimen, the operator locks the bottom jaw open, then opens the upper jaw and places the top half of the specimen inside. Once the specimen is clamped securely within the upper jaw, the operator positions the bottom half of the specimen into the lower grip jaws and unlocks the jaws, providing clamping force and securing the specimen so that the test may be conducted. 

In the screw type actuation (offered in the 20,000 pound capacity model), a mechanical screw actuator, which is operated manually by turning a handle, opens and closes the grip jaws. This screw actuation provides a more secure initial gripping force and is ideal for hard materials testing where occurrences of slippage are prevalent.

Domaine d'application

  • Type of Loading: static tension 
  • Specimen Material: wires, plastics, metals, elastomers 
  • Specimen Types: flat or round specimens

Principe de fonctionnement

The specimen is supported on two precision machined (free to rotate or stationary) anvils of a defined radius. The force is applied either centrally (3 point) or at a defined distance either side of the center (4 point). The support beam is graduated lengthways in metric units for accurate positioning of the anvils, equally spaced to the center line.

This feature also applies to the 4 point loading beam and anvils.

Accessoires d'essai » Application Specific Fixtures » Paper and board » Page 16

Paper and board

Paper and paper board testing is important to the pulp and paper industry because of the demands placed upon it for a wide range of applications. 

In printing, for example, paper is handled from either cut sheets or rolls (webs) and the tensile strength and elongation properties must meet stringent customer requirements. In packaging, testing of corrugated paper is performed to measure the resistance of edgewise compression.

Principe de fonctionnement

TAPPI standards are applied for standard testing practices. Edgewise compression strength is tested per T-472 using special fixturing. Tensile breaking strength per T-404 is performed by using a set of Screw or Pneumatic side action grips with appropriate faces.

Domaine d'application

  • Testing method: Tensile, compression, puncture 
  • Specimen type: Paper (dry and wet), corrugated board (dry and wet)

Axial-Torsion Wedge Grips

Axial-Torsion Wedge Grips

The application of both axial and torsional forces simultaneously under fatigue conditions requires special grip design. These grips utilize a wedge-action gripping technique making them suitable for flat specimens as well as cylindrical.

Principe de fonctionnement

The major grip components are the grip driver, wedge grip head, grip attachment flange and jaw faces.

The grip driver applies the clamping force to the grip head by moving it relative to the jaw faces.This causes the the jaw faces to clamping the specimen. 

The grip drive also incorporates 3 sets of anti-rotation sliders that transfer any applied torque from the actuator to the grip and specimen. The jaw faces are either serrated or V-grooved to accommodate flat or cylindrical specimens.

Domaine d'application

  • Axial/Torsion tests on flat or cylindrical specimens

Hydraulic Wedge Action Grips

Hydraulic Wedge Action Grips

Hydraulic wedge action grips feature an open front design, which facilitates easy loading of large specimens. This series can accommodate round specimens up to 90 mm (3.54 in) in diameter and flat specimens up to 90 mm (3.54 in) thick with capacities ranging from 300kN (67,500 lbf) to 2000kN (450,000 lbf).

Specially suited for industrial environments where dust and metal chips may be present, these grips have protective dust covers that fit easily over the faces to shield the moving surfaces. Optional adapter plates furnish an efficient method for mounting secondary load strings for lower capacity testing or other fixturing without removing the larger grip. 

Principe de fonctionnement

These grips are hydraulically operated via a manually rotated knob on the front of the grip. The grip body does not move during closing or opening. Hydraulic supply is typically from the main machine frame via a grip sub-manifold. Jaws are separable inserts held in a jaw carrier which are easy to install with no need to re-grease when changing jaw faces. Grip bodies have grease fittings to allow easy re-greasing of the carrier when needed. W-5380 and W-5390 feature magnetic seating.
