EP EPA1 en The utility model has a Charpy pendulum whose main characteristic is the support plate which actuators pendulum support. Is screwed anglo the mass notch: Kind code of ref document: The advanced control system that controls a pneumatic brake has a button to release and angle transducer 12 to reactivate when it detects the exceeding of a certain level or angle change of the mass 7.

xe If the angle exceeds the impact so that the bulk of the mass 7 can hit the specimen the brake is applied before this happens. En este caso se trata de resolver la necesidad de ampliar el rango y el tipo de In this case it comes to solving the need anguloo expand the range and type of.

Figures 3 and 4 show examples of system junction impacts on a test bench. With the data of surface inclination and the angle of impact energy that has to rise the device is calculated.

The angle transducer 12 to the shaft 3 is also connected on the outside thereof and measures the angle that rotates the pendulum. Device pendulum impact test low energy according to the first claim, characterized by having a pushbutton to release the air brake and control system to activate when the angle transducer 12 detects that exceeds a certain level or a change of angle of the mass 7 occurs.

Pêndulo Charpy

The present invention is encompassed within the field of tests using a pendulum impact on a specimen. Consists of a bed 1 anhulo wings 2 on both the axis of rotation 3 as the pliers 4 of the brake, cbarpy arm 6 having through holes 10 and a mass supported 7 sliding through the arm 6 and fixed on it, and finally an interchangeable impactor 11 is screwed into charrpy mass 7.


Se detecta cuando el giro del dispositivo cambia de sentido tras el impacto. Country of ref document: In Figures 3 a practical charp of the invention is shown wherein the device anchor in one of the columns of a portico. It is detected when the rotation of the device changes direction after impact. The assembly of the wings 2 takes up very little surface of the bed 1being free most of the surface. It also has a security system to prevent damage to the specimen if the aangulo energy is too large.

Other similar systems studied to date are designed for impact on specimens or specimens of small size that are placed on the pendulum device itself. The tip of the impactor 11 is an interchangeable tip that binds to the mass 7 by a threaded connection. Sobre la masa va atornillada la entalla: By a push arm is released and impact run.

In relation to the arm and the mass, the mass is displaced and fixed along the arm as the impact energy needed. The flexibility in use, angupo easy adaptation to different places set, to be a portable device. Patent ES in which a pendulum for testing having a modular configuration, an arm operated anuglo a reducer and characterized motor described because its operation is carried out by operation of an electromagnet that releases the mass disposed at the end of the arm.

Figure 1 shows a perspective view of the embodiment of the invention. Figure 2 shows another view of the invention to provide a complete view of it, showing the elements that are not clearly seen in Figure 1.

El control del sistema frena el dispositivo una vez ejecutado el impacto. It is another object of the invention that the pendulum is provided on a base that is adaptable to any arrangement, either horizontal, vertical, inclined or even on the same specimen. The joint system of the bed is set based on the specimen to impact.

In the state of the art impact devices pendulum they are mainly used for destructive testing. At the ends of said bed 1 the wings of the ed 2 where the axis of rotation 3 and the brake calipers 4 is mounted are arranged. Device pendulum impact test low energy according to the first claim, characterized in that the various means for fixing the bed 1 outside the wings 2magnetic media, based clamps or screw connectionsallow. The pneumatic system is lower agnulo and a smaller electric braking system.


Binding arm 6 with the axis 3 is consolidated with oblique supports 8 and the corresponding part of agulo shaft 3 at its junction with the arm 6 and two oblique supports 8 changes its cylindrical design for angullo rectangular design where the connecting points 9 are established. Impact pendulum-type testing machine for testing samples of materials with repeated impacts.

The bank has a design that allows installation anywhere: The impact energy to be performed on the specimen.

This plate is required due to the large dimensions of the pendulum. Pendulum device for testing low energy impacts the type used for characterization of materials by the Charpy method, characterized by having a control system which prevents recoil or rebound further damage on the desired material.

The software associated with the device automatically brakes the pendulum when it has reached the desired angle. Brake disks 5 are supported on the shaft 3 and arranged with wings 2 of the bed. The grippers 4 are supported only in the wings 2 without resting on the bed 1 leaving the maximum area with free access. The test set angjlo parameters depending on the type of material angul the use of different masses which can be se in different positions, allowing in a simple change of the inertia of the pendulum.

From airplane wings, boats etc. The advantages of the device of the invention are: The dough is firmly joined to the arm via a connecting bolt passing through both. Also on the axis of rotation 3 the arm 6 ending in a mass 7 constituting all the pendulum is fixed.
