The cast in rail shoulders body has a basically fixed chuck. A portion of the torsion sample is secured by two flat and clamping bolts. On the base is an electric motor that moves horizontally. Reduction gear. The left end is a rotating chuck that holds the other end of the sample in place. When the electric accelerator is rotating, the movable chuck is driven to rotate, so that one end of the sample is rotated against the other end, so that the sample is distorted.

The torque acting on the specimen is balanced by a weighing mechanism connected to a fixed chuck, while the load pointer is driven to rotate to indicate the magnitude of the torque. It also drives the pen of the plotter from side to side. The moment coordinate of this motion is perpendicular to the length of the paper on the recording paper.

The rotation of the dynamic chuck represents the rotation of one end of the sample with respect to the other end, that is, the torsion Angle. The size of the torsion Angle is indicated by the scale on the movable chuck. At the same time, the rotation Angle signal is input to the plotter through the rotation sensor, the paper tube of the plotter is driven to rotate, and the recording paper is output. The angular coordinates are formed along the length of the recording paper.

In the course of the test, with the increase of the torsion deformation of the specimen, the torque of the specimen also changes. The plotter draws the test curve of torque and torsion Angle.

That's how cast in rail shoulders work. The test principle of different test performance testing machines is also different. Once you understand the fundamentals of cast in rail shoulders, you can test different samples. Horizontal tensile testing machine adopts all-steel welded frame structure, single-rod double-acting piston cylinder to apply test force, hydraulic pressure automatically clamp the sample, weighing sensor to measure the force, the length can be adjusted according to the sample specifications. Expand the space, the computer screen displays the test force and test curve, and the test data can be automatically processed according to the test method requirements. This machine is the ideal test equipment for coal power enterprises, coal mine machinery and equipment, safety production inspection institutions, technical supervision and other industries. It works with wires. The tensile load and failure test of cable, porcelain bottle, double hook, steel strand, safety belt, waist rope, foot buckle and other products require flexible and convenient operation, slow and stable loading, and strong bearing capacity.

Microcomputer controlled multi-closed-loop material testing machine measurement and control system - can achieve displacement, stress, strain and other closed-loop control, smooth conversion between each other, no impact. It can meet the test requirements of different test areas and different test control methods: constant stress, constant strain, load maintenance and other special requirements; In the test process, according to the set program automatically smooth switching.

The cast in rail shoulders is composed of steel plate welded frame structure, the test space beam is dynamically adjusted in sections, the test force is applied to the single rod double acting piston cylinder, the test process is controlled manually or by servo, the load sensor is measured, and the test force and test curve are displayed by the computer.
