Thermal aging stress relief is generally suitable for small workpieces, while the lifting foundation structure has a large volume and does not have a large enough annealing furnace. Using natural aging takes one year and the production cycle is too long, so neither of these two methods is feasible. After research and understanding by the manufacturer, it was found that selecting appropriate support points for large welded structural components can perform vibration aging stress relief. Therefore, the manufacturer has decided to use vibration aging for stress relief of the platform lifting foundation.

The 11 folding arm lifting platform product can also use a 50Hz, 380V power motor, and diesel engine dual power.
Vibration aging treatment and effect judgment: According to the aging process plan, after setting the support points and vibration pickup points of the workpiece, use a rigid fixture to fix the exciter on the workpiece and use the manual function of the equipment to test the vibration. It is determined that around 5300 revolutions is the resonance frequency of the component. The amplitude generated by the eccentric gear of the exciter in the fourth gear can meet the vibration processing requirements of the foundation seat, so the excitation force is selected as the fourth gear.
average method.However, large welded structural components have the characteristics of complex morphology, large weight, large differences in residual stress size and distribution, and it is difficult to achieve good results using ordinary vibration aging technology. Therefore, it is crucial to develop a reasonable process. Therefore, they found Nanjing Juhang and our JH-700 vibration aging equipment, and requested us to develop a complete vibration aging process.

Esselstein.Now with the arrival of summer the aluminum alloy lifting platform will certainly suffer from high temperature and rainstorm in summer. It is easy to rust after a long time under this condition, which will seriously shorten the service life of the equipment and cause safety problems. So how should we prevent equipment rust?
During aging treatment, the front end of the a-t curve shows an upward trend, indicating that the damping inside the component decreases after vibration treatment so the amplitude gradually increases; Since then, the amplitude change has been basically stable, indicating that the structure of molecules inside the component tends to be stable, which conforms to the judgment standard of curve observation strip, thus it can be determined that the workpiece has reached the effect. The precautions for using an electric lifting platform are as follows: the user unit should arrange a dedicated person to operate the lifting platform and develop details and safety precautions for the use of the lifting platform based on their own unit's situation, and hang it in a prominent position. When working on an electric lifting platform, professional drivers and operators must be equipped, and they must undergo specialized training and be qualified. They must hold relevant certificates and take on corresponding responsibilities according to the actual situation of the work. After the construction is completed,EsselsteinElectric aluminum alloy lifting platform, the lifting platform needs to be moved on the site and should be operated by a professional driver.
