Se detecta cuando el giro del dispositivo cambia de sentido tras el impacto. De esta manera se consigue que el movimiento de ambos elementos sea solidario. It also has a security system to prevent damage to the specimen if the selected energy is too large. With the data of surface inclination and the angle of impact energy chafpy has to rise the device is calculated.

Country of ref document: Device pendulum impact test low energy according to the first claim, characterized in that the arm 6 and mass 7 are joined by a pin and the mass se has an impactor 11 interchangeably by screwing the tip.

The method of using the aforementioned pendulum device solves the problems that may arise in the execution of all types of impacts with this device. The advantages of the device of the invention are: The present invention is encompassed within the field of tests using a pendulum impact on a specimen.

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.

Thus it is achieved that the movement of both elements is integral. El brazo 6 tiene agujeros 10 en su superficie marcando las diferentes posiciones en las The arm anggulo has holes 10 on its surface marking the different positions in the. The angle of the surface on which is to impact measured with an inclinometer.

Specifically, the impact device consists of a pendulum with a system of variable weights are placed in different positions of the arm to provide greater flexibility to the system as to the impact energies that can be set.

Braking system control angupo once executed the impact. This angle can be any: Charph then goes on to describe very briefly a series of drawings which aid in better understanding the invention and which are expressly related to an embodiment of said invention presented as a non-limiting example thereof. Figure 1 shows a perspective view of the embodiment of the invention.

EP EPA1 en The pneumatic system is charpg consumption and a smaller electric braking system. Adaptability to any test site for the use of an efficient air braking system. 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. The method followed for use is as follows: En este caso se trata de resolver la necesidad de ampliar el rango y el ahgulo de In this case it comes to solving the need to expand the range and type of.

The object of this device is to perform controlled in the specimen, in no case cause breakage or excessive damage to the damage. The assembly of the wings 2 takes up very little surface of the bed 1being free most of the surface. Brake disks 5 are supported on the shaft 3 and arranged with wings 2 of the bed. The different positions can take the mass 7 increase system flexibility because different impact energies are achieved by moving the mass 7. To solve this and other problems has developed the pendulum impactor of the invention.


Pendulums are characterizations of materials for the Charpy method where the resistance is measured at break of a specimen when impacted using a pendulum with a hammer on the end. The software associated with the device automatically brakes the pendulum when it has reached the desired angle.

The brake comprises two brake discs attached to the shaft and two pneumatic grippers. ES Kind code of ref document: El control del sistema frena el dispositivo una vez ejecutado el impacto. Binding arm 6 with the axis 3 is consolidated with oblique supports 8 and the corresponding part of the shaft 3 at its junction with the arm 6 and two oblique supports 8 changes its cylindrical design for a rectangular design where the connecting points 9 are established.

Said device is provided with a braking system which controls the height of the impact once defined the energy ed with which will impact and similarly this braking system avoids rebound after impact. The hammer is intrumentalizado and the device has a data acquisition system. The joint system of the bed is set based on the specimen to impact.

The utility model has a Charpy pendulum anulo main characteristic is the support plate which actuators pendulum support. By a push arm is released and impact run. 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.
