It is detected when the rotation of the device changes direction after impact. The grippers 4 are supported only in the wings 2 without resting on the bed 1 leaving the maximum area with free access. De esta manera se consigue que el movimiento de ambos elementos sea solidario. The angle of the surface on which is to impact measured with an inclinometer. The pneumatic system is lower consumption and a smaller electric braking system.
The bank has a design that allows installation anywhere: It 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.
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.
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. 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. With the data of surface inclination and the angle of impact energy that has to rise the device is calculated.
This angle can be any: Braking system control device once executed the impact.

In any case, this and other devices pendulum not adequately solve the problems associated with the location of the specimen when the part to be evaluated is large or problems regarding the use of different types of arms and different body types to determine the most appropriate inertia. Device pendulum impact test low energy according to the first claim, characterized in that the axis of rotation 3 is cylindrical in the portion corresponding to the wings 2 and brake disks 5 and transitions a rectangular binding arm 6 and support points 8 which reinforce said arm 6.
Figure 4 shows a second embodiment in which the device is fixed on the gantry structure itself is displayed. It is another object of the invention is that the brake tire, are available around the axis and its instantaneous actuation input better yields to impact and avoid rebound effect after the blow with the 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.
Are arranged Tong anchored in the wings of the bed to leave the base of free bed and can easily be tied to any surface. 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.
Consists of a bed 1 and wings 2 on both the axis of rotation 3 as the pliers 4 of the brake, an 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 the mass 7. Angulk relation to the arm and the mass, the mass is displaced and fixed along the arm as the impact energy needed. The test set different parameters depending on the type of material through the use of different masses which can be fixed in different positions, allowing in a simple chadpy of the inertia of the pendulum.
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 to expand the range and type of. Is screwed on the mass notch: The impact energy to be charpyy on the specimen. It is an object of the invention to establish different test parameters depending on the type of material and the notch of the hammer, providing the pendulum of a single arm adapted for the mass of the recess can be moved by it and located in different positions.
The method followed for use is as follows: The software associated with the device automatically brakes the pendulum when it has reached the desired angle. Thus it is achieved that the movement of both elements is integral. Device pendulum impact test low energy according to the first claim, characterized in that chadpy arm 6 and mass 7 are joined by a pin and the mass 7 has an impactor 11 interchangeably by screwing the tip.
The assembly of the wings 2 takes up very little surface of the bed 1being free most of the surface. Binding arm charpt 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. The tip of the impactor dharpy is an interchangeable tip that binds to the mass 7 by a threaded connection.
From airplane charrpy, boats etc. EP EPA1 en The hammer is intrumentalizado and the device has a data acquisition system. Kind code of ref document: Device for pendulum impact test low energy type used for validations materials Charpy method including a bed on which wings housing the rotation anggulo arm system is yerguen braking, characterized in that: The aangulo invention is encompassed within the field of tests using a pendulum impact on a specimen.
Figure 2 shows another view of the invention to chaepy a complete view of it, showing the elements that are not clearly seen in Figure 1.
This plate is required due to the large dimensions of the pendulum. The flexibility in use, with easy adaptation to different places set, to be a portable device. Mediante un pulsador se libera el brazo y se ejecuta el impacto.

Los discos de freno 5 se soportan sobre el eje 3 y se disponen junto a las alas 2 de la bancada. The object of this device is to perform controlled in the specimen, in no case cause breakage or excessive damage to the damage.
The brake comprises two brake discs attached to the shaft and two pneumatic grippers. The device is compact and chrapy and can bind to different tool in horizontal, vertical or inclined managed to obtain impacts in any direction. Country of ref document: Adaptability to any test site for the use of an efficient air braking system. Se detecta cuando el giro del dispositivo chaepy de sentido tras el impacto. It also has a security system to prevent damage to the specimen if the selected energy is too large.

Pendulums are characterizations dr 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 angle transducer 12 to the shaft 3 is also connected on the outside thereof and measures the angle that rotates the pendulum. The dough is firmly joined to the arm via a connecting bolt passing through both.
