NiorSelf prope
NiorRail-type The lifting foundation of the platform is a large structural component made of alloy steel plates with different thicknesses that are welded together. The welding amount is large, the structural shape is complex, it is necessary to perform stress relief treatment on the completed components.
The design of support points for selecting process parameters is to avoid energy consumption and noise generation due to collision between components and supports during vibration. The supports should be arranged near the nodal line and the layout principle is: when the aspect ratio of the component is greater than 2, two point supports can be used; When the aspect ratio is close to 1 it is advisable to use or 4-point support.
Nior.Regularly check the connection of each part and tighten it if there is any looseness. The tightness of the body connecting bolts should be checked when the body is under pressure (the rotating arm can be used to cause compression)
Thermal aging stress relief is generally suitable for small workpieces, 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. Long term promotion of downgrading manufacturers, 20 year old brand, with price advantages and guaranteed quality!
.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.
However, large welded structural components have the characteristics of complex morphology, 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.

Firstly, it is necessary to start from the source. The current technology is relatively advanced. When manufacturing aluminum alloy lifting platforms, which steel should be chosen for production? Because there are many corrosion-resistant steel materials now, adding chromium, nickel, etc. to ordinary steel to make stainless steel, changing the internal structure of the metal to prevent rust.
The second method is the protective layer method, which covers the metal surface of the aluminum alloy lifting platform with a protective layer to isolate the metal products from the surrounding corrosive medium and prevent corrosion. Apply engine oil, petroleum jelly, paint, or cover the surface of steel parts with corrosion-resistant non-metallic materials such as enamel and plastic; Using electroplating hot plating, spray plating, etc. to coat the surface of steel with a layer that is not easily corroded
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?

Every customer pays attention to the price of elevators, so how does the manufacturer calculate the price of elevators? In general, the manufacturer calculates the price of the elevator for customers based on the actual size, height, as the different materials used, material brands, and production processes result in different prices for elevators Customers can consider the cost-effectiveness of elevators more when purchasing, with the principle of getting what they pay for. Safety hazard elimination plan for lifting cargo elevators: When there is a malfunction or abnormal situation in the lifting cargo elevator, it should be immediately stopped from use. After eliminating the malfunction and accident hazards, it can be put back into use
The vibration frequency should be set to obtain large dynamic stress with low energy consumption, and the resonance frequency should be used to handle time dependent vibration. However, there may be one or more resonance peaks in large components, and using resonance peaks with higher peaks and lower frequencies for aging can achieve optimal results. The resonance frequency needs to be determined by trial vibration, which slowly increases the speed of the excitation motor from 0, and determines the relationship curve between the amplitude of the workpiece and the motor speed to determine the resonance point of the workpiece. According to the scanning curve, a large acceleration was obtained at 5366r/min, so 5366r/min was determined as the aging frequency.
Nior.During aging treatment, the equipment prints the vibration aging curve online. According to the curve, the front end of the a-t curve shows an upward trend, indicating that the damping inside the component decreases after vibration treatment,NiorSingle rail lifting platform, 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, the lifting platform needs to be moved on the site and should be operated by a professional driver. Before daily work, zy12 drivers must carefully check the electrical, hydraulic and mechanical systems of the platform, check the working range of the lifting platform truck, and remove obstacles that hinder the rotation and walking of the lifting platform truck.
