Description

Background technique

As the most promising surface strengthening process for cold working of metal materials, ultrasonic strengthening has a wide range of applications in the process of mechanical manufacturing. Orthopedics of deformed components caused by machining such as casting, welding, stamping, etc.

The ultrasonic strengthening process mainly uses injection parts such as pellets or strikers. Under the action of ultrasonic waves, the surface of the structural parts is impacted at high speed, so that a strengthening layer is formed on the surface of the structural parts, so as to improve the fatigue life and stress corrosion resistance of the structural parts.

The ultrasonic strengthening equipment in the prior art mainly relies on the gravity of the injection part itself or with the help of negative pressure suction to make the injection part hit the workpiece and start up again, so that the injection part continuously collides with the ultrasonic vibration horn, so that the injection part It is continuously excited and sprayed out to strengthen the surface of the workpiece.

Therefore, the processing direction of the workpiece is limited, and the workpiece needs to be constantly turned over to make the different surfaces of the workpiece. Towards the ultrasonic strengthening device.

When the ejector is activated with the help of negative pressure suction, on the one hand, due to the effect of negative pressure suction, it is very easy to cause impurities such as metal chips or dust to be sucked into the inside of the ultrasonic strengthening equipment, causing the risk of electrical equipment to be disconnected, causing equipment failure, or It affects the smoothness of the movement of the injection parts and affects the craftsmanship of the surface treatment of the workpiece. On the other hand, since the maximum pressure of negative pressure is one atmospheric pressure, the adsorption pressure has an upper limit. Therefore, this method is only suitable for a very small number of or light-weight injection parts, for example, using a single striker or a very small number of strikers for Strengthening treatment of single point or line, such as stress relief of welds, etc. For larger size and heavier gravitational ejection parts, the negative pressure usually cannot adsorb the ejection parts to the surface of the ultrasonic vibration horn, so that the ejection parts are ejected, or the impact force of the ejection parts is small, resulting in the workpiece The strength after surface strengthening treatment is relatively low.

It can be understood that, since the pressure-bearing surface 21 is an inclined surface, and according to the force of the inclined surface, it can be known that the pressure-bearing surface 21 is connected from the end connected with the second cylindrical portion 23 to the end connected with the first cylindrical portion 22 . , the radial dimension of the pressure bearing surface 21 is gradually reduced, that is, the radial dimension of the second columnar portion 23 is larger than the radial dimension of the first columnar portion 22 .

Since the minimum radial dimension of the pressure bearing surface 21 is greater than or equal to the diameter of the first injection hole, that is, the pressure bearing surface 21 cannot pass through the first injection hole, when the part with the smallest radial dimension of the pressure bearing surface 21 moves to the first injection hole When injecting the hole, the pressure-bearing surface 21 collides with the hole wall of the first injection hole, and the injection body 2 cannot continue to run in the direction close to the first injection hole, that is, at this time, it is the position of the maximum stroke of the injection body 2, At this time, one end of the ejection body 2 protruding from the first ejection hole is in contact with the surface of the workpiece, and impacts the surface of the workpiece.

Obviously, at this time, the positive pressure gas in the airflow channel 31 can act on the entire inclined surface. After the ejector 2 collides with the workpiece, the ejector 2 collides with the vibrating body 13 in the opposite direction under the action of the positive pressure gas.

Considering the convenience of installation, to avoid the ejection body 2 falling from the second ejection hole during installation, on the basis of the above-mentioned embodiment, the end cover 3 further includes a partition 34, and the partition 34 is arranged on the cover body 32 away from the top. At one end of the cover 33, the partition plate 34 is provided with a third injection hole, and the third injection hole and the second injection hole are arranged in a one-to-one correspondence; A limiting portion 25 is provided between the two columnar portions 23 and the third columnar portion 24 , and the minimum radial dimension of the limiting portion 25 is greater than or equal to the diameter of the third injection hole.

It should be noted that, the cover body 32 and the partition plate 34 can be fixed by welding or by bolts.

It should be further noted that, in the above embodiments, the present invention does not limit the specific shape of the impact end 221 of the injection body 2 for contacting the workpiece surface. As shown in FIG. 3 and FIG. 2 is suitable for workpiece surfaces of different shapes. On the basis of the above-mentioned embodiments, the shape of the impact end 221 of the ejector 2 for contacting the workpiece surface is a plane, an arc surface, a spherical surface or a sharp angle, etc. Personnel can be selected according to actual needs.

It can be understood that the impact strength of the ejector 2 is related to the positive pressure exerted on it by the positive pressure gas and the vibration energy of the vibrating body 13. Therefore, in this embodiment, the controller 5 controls the output power and the positive pressure of the ultrasonic power supply 11 respectively. The air flow of the air source 4 is used to make the positive pressure generated by the positive pressure gas on the ejector 2 and the vibration energy of the vibrating body 13 work together, so that the ejector 2 has a suitable impact strength.
