The software associated with the device automatically brakes the angul when it has reached the desired angle. El control del sistema frena el dispositivo una vez ejecutado el impacto.
En este caso se trata de resolver la necesidad de cbarpy el rango y el tipo de In this case it comes to solving the need to expand the range and type of. Los discos de freno 5 se soportan sobre el eje 3 y se disponen junto a las alas 2 de la bancada. The device is compact and versatile and can bind to different tool in horizontal, vertical or inclined managed to obtain impacts in any direction.

The pneumatic system is lower consumption and a smaller electric braking system. The test set different parameters depending on chwrpy 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. This plate is required due to the large dimensions of the pendulum. Figure 2 shows another charpj of the invention to provide a complete view of it, showing the elements that are not clearly seen in Figure 1.
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.
Is screwed on the mass notch: 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. 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.
The dough is firmly joined to the arm via a connecting bolt passing through both. Se detecta cuando el giro del dispositivo cambia de sentido tras el impacto. Braking system control device once executed the impact. Esta es una de las This is one of the. The angle of the surface on which is to impact measured with an inclinometer. Wind tunnel test method to study out-of-service tower crane behaviour in storm winds. 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 has an impactor 11 interchangeably by screwing the tip.
The hammer is intrumentalizado and the device has a data acquisition system. 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.
In the state of the art impact devices pendulum they are mainly used for destructive testing. 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. Adaptability to any test site for the use of an efficient air braking system. De esta manera se consigue que el movimiento de ambos elementos sea solidario.
Brake disks 5 are supported on the shaft 3 and arranged with wings 2 of the bed. 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.
Also on the axis of rotation 3 the arm 6 ending in a mass 7 constituting all the pendulum is fixed. The present invention is encompassed within the field of tests using a pendulum impact on a 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.

Figures 3 and 4 show examples of system junction impacts on a test bench. 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: The brake comprises two brake discs attached to the shaft and two pneumatic grippers.
It is detected when the rotation of the device changes direction after impact. 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. Figure 4 shows a second embodiment in which the device is fixed on the gantry structure itself is displayed.
The flexibility in use, with easy adaptation to different places set, to be a portable device. This angle can be any: It also has a security system to prevent damage to the specimen if the selected energy is too large. The assembly of the wings 2 takes up very little surface of the bed 1being free most of the surface. 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.
Mediante un pulsador se libera el brazo y se ejecuta el impacto. In Figures 3 a practical embodiment of the invention is shown wherein the device anchor in one of the columns of a portico.
To solve this and other problems has developed the pendulum impactor of the invention. Sobre la masa va atornillada la entalla: 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.
The object of this device is to perform controlled in the specimen, in no case cause breakage or excessive damage to the damage. Impact pendulum-type testing machine for testing samples of materials with repeated impacts.
From airplane wings, boats etc. The bank has a design that allows installation anywhere:
