IIIVibration aging deviceSupport method for square or circular workpieces

1When the length of the workpiece≈wide≈When it is high, it is considered that the workpiece belongs to the square type. Rubber pads can be made of three types Point support method, the exciter is placed at the end of the single support point or in the middle of the workpiece top surface, and the sensor is placed at the other end, as shown in the following figure3.

2When the workpiece is a circular ring, the rubber pad is supported by four or three symmetrical supports at the bottom of the ring, the exciter is sandwiched between two rubber pads, and the sensor is placed between the other two rubber pads, as shown in the figure4.

Time sensitive processing machine, time sensitive processing equipmentprocess

*Step: Time preparation: Use a rubber pad to support the workpiece to be time treated at its joint line attachment, and firmly fix the exciter with a bow shaped fixture at the peak of the workpiece vibration. Use a magnetic seat to firmly attach the sensor for testing the workpiece vibration situation to the workpiece, and connect the exciter, sensor, and controller with a cable.

Step 2: Pre vibration scanning: The welding stress relief equipment detects the natural resonance frequency of the aging treated workpiece and the amount of vibration energy that should be given to the workpiece in an automatic scanning manner, and stores them.

Step 3: Stress relief: The vibration aging equipment automatically (or manually) determines the vibration frequency for vibration treatment of the workpiece based on the parameters measured in the second step, and performs vibration aging treatment on the workpiece. Detect changes in vibration parameters and residual stress of the workpiece at any time during the processing, and stop the processing process promptly when the residual stress is no longer eliminated.

Step 4: Result determination: The vibration aging equipment automatically re checks the parameters of the workpiece being aged, in order to determine the basisJB／T5926—2005Standard for determining the effectiveness of vibration aging.

Stress relief equipmentResult determination

according toJB/T5926—2005When one of the following situations occurs, it can be determined that the vibration aging process effect has been achieved according to the standard (Machinery Industry Standard of the People's Republic of China).

a.Amplitude time（a—t）The curve rises and then flattens;

b.Amplitude time（a—t）The curve rises, then falls, and finally flattens;

c.Amplitude frequency（a—n）The peak acceleration after curve oscillation increases compared to before oscillation;

d.Amplitude frequency（a—n）The resonance frequency of the curve after vibration decreases compared to before vibration;

e.Amplitude frequency（a—n）The bandwidth of the curve after vibration becomes narrower than before vibration;

fAmplitude frequency（a—n）The resonance peak of the curve exhibits fission phenomenon.

LM-ZNfully automaticWelding stress relief equipmentFeatures:

1It has four time sensitive processing control modes: fully automatic, timed fully automatic, semi-automatic, and manual, all of which have fine adjustment functions. The operator can choose according to the on-site situation.

2The fully industrial control chassis is designed with openings, which can effectively block external radiation interference, ensure that the internal components of the computer are not affected by external radiation, and increase the heat dissipation effect

3、 The CPU adopts ARM9 microcontroller, which can run four thread solidified programs simultaneously, increasing the running speed of the entire device by more than three times.

4The entire circuit has undergone quantum vacuum coating treatment, and the equipment has achieved waterproof, moisture-proof, anti-static, and shockproof properties, enhancing the equipment's requirements for the operating environment and greatly improving its service life

5The dual eccentric permanent magnet slotless high-speed DC exciter configured has the characteristics of high speed stability accuracy, low heat generation, and durability. By combining microcomputer and pulse width modulation technology, it has high data processing capability and speed stability, with a speed stability accuracy of ± 0.5r/min. The service life is three times that of similar products in the industry

6Adopting a three-dimensional piezoelectric sensor detection method, where the sensor is placed in a certain position, it can sense any direction of vibration at this position and accurately transmit it to the host.

7Using a thermal micro printer instead of traditional needle printers, it solves the problems of difficult paper and ribbon changes and ink addition, and improves printing speed

8Adopting a dynamic high-definition LED LCD display screen, with a viewing angle of up to 160 °, the data on the screen can be clearly seen at any angle. Having a higher refresh rate, faster and smoother data updates, dynamic display of scan analysis curves a-n and aging processing curves a-t, as well as data comparison, the aging process and curve trends are clear at a glance, and the human-machine dialogue function is more efficient.

9Protection function: automatic voltage overload, current overload, high-frequency runaway warning prompt and other protection functions greatly improve the safety of on-site operations and ensure safe production on site.
