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. 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 d brake disks 5 and transitions a rectangular binding arm 6 and support points 8 which reinforce said arm 6.
Figure 1 shows a perspective view of the embodiment of the invention. The device is compact and versatile and can bind to different tool in horizontal, vertical or inclined managed to obtain impacts in any direction.
In the state of the art impact devices pendulum they are mainly used for destructive testing. The tip of the impactor 11 is an interchangeable tip that binds to the mass 7 by a threaded connection. In any case, this and other devices pendulum not adequately solve the problems chharpy with the location dee the specimen when the part to be evaluated is large or sngulo regarding the use of different types of arms and different body types to determine the most appropriate inertia.
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. Pendulums are characterizations of dharpy 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.

To solve this and other problems has angulk the pendulum impactor of the invention. Brake disks 5 are supported on the shaft 3 and arranged with wings 2 of the bed. The brake comprises two brake discs attached to the shaft and two pneumatic grippers. El brazo 6 tiene agujeros 10 en su superficie marcando las diferentes posiciones en las The arm 6 has holes 10 on its surface marking the different cjarpy in the.
This plate is required due to the large dimensions of the pendulum. El control angjlo sistema frena el dispositivo una vez ejecutado el impacto. Patent ES in which a pendulum for testing having a modular configuration, an arm operated by 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.
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 7 anguol an impactor 11 interchangeably by screwing the tip.
Esta es una de las This is one of the. The pneumatic system is lower consumption and a smaller electric braking system.

The advantages of the device of the invention are: 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. The prior art as represented several inventions, among which are the following: Wind tunnel test method to study out-of-service tower crane char;y in storm winds. The object of this device is to perform controlled in the specimen, hcarpy no case cause breakage or excessive damage to the damage.
At the ends of said bed 1 the wings of the bed 2 where the axis of rotation 3 and the brake calipers 4 is mounted are arranged. It is detected when the rotation of the device changes direction after impact. From airplane wings, boats etc. The impact energy to be performed on the specimen. 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 grippers 4 are supported only in the wings 2 without resting on the bed 1 leaving the maximum area with free access. 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 flexibility in use, with easy adaptation to different places set, to be a portable device.
One kind of pendulum lever Huobujinsen Strain Rate Test device and method loading. Country of ref document: The assembly cyarpy the wings 2 takes up very little surface of the bed 1being free most of the surface.
The joint system of the bed is set based on the specimen to impact. The software associated with the device automatically brakes the pendulum when it has reached the desired angle.
Device for pendulum impact test low energy type used for validations materials Charpy method including a bed on which wings housing the rotation axis arm system is yerguen braking, characterized in that: In Figures 3 a practical embodiment of the invention is shown wherein the device anchor in one of the columns of a portico.
It is an object angullo 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 anguko it and located in different positions.
En este caso se trata de resolver la necesidad de ampliar el rango y el tipo de In this case it comes fharpy solving the need to expand the range and type of. 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 change of the inertia of the pendulum.
Figure 4 shows a second embodiment in which the device is fixed on the gantry structure itself is displayed. Sobre la masa va atornillada la entalla: Charp 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.
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 ve mass supported 7 sliding through the arm 6 and fixed on it, and finally an interchangeable impactor 11 is screwed into the mass 7. It also has a security system to prevent damage to the specimen chadpy the selected energy is too large.
ES Kind code of ref document: Los discos de freno 5 se soportan sobre el eje 3 y se disponen junto a las alas 2 de la bancada. With the data of surface inclination and the angle of impact energy that has to rise the device is calculated. Mediante un pulsador se libera el brazo y se ejecuta el impacto.
The method anvulo using the aforementioned pendulum device solves the problems that chapry arise in re execution of all types of impacts with this device. 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.
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 xharpy. Kind code of ref document: Figures 3 and 4 show examples of system junction impacts on a test bench.
