10.The ultra-high cost-effectiveness has become an important factor for many users!

2、 Main components composition

The vibration aging machine, vibration aging machine, and complete set of vibration aging machinery mainly include: vibration aging main controller, exciter, shock absorber rubber pad, vibration aging pickup, five core cable, charge shielding cable, clamp, power cable, and commonly used accessories.

3、 Main working process

1.Pre vibration scanning: After starting up, the workpiece is scanned for vibration within the frequency range of 0-10000 to find the appropriate aging frequency for the workpiece and provide a basis for later data processing judgment

2.Search for sub resonance points in vibration aging: After vibration aging scanning, calculate the effective sub resonance frequency points based on the scanned data and select the appropriate amplitude.

3.Aging in progress: Hengfu vibration aging is carried out according to the data of the sub resonance point of vibration aging, and the strain effectively eliminates residual stress.

4.After vibration scanning: After the aging process is completed, the aging workpiece is re scanned for frequency processing, and in accordance with national standards, the effectiveness of the vibration aging effect is judged

5.Print data: Print the curve and data of the entire aging process and results to effectively save the stress relief data of this workpiece.

Most of the exciters used by domestic vibration aging equipment manufacturers are high-speed DC exciters produced by Baotou Permanent Magnet, generally divided into 5 aging tonnages:

K10-2 tons K2:0-20 tons K3:0-50 tons K4:0-100 tons K5:0-500 tons Customers can choose the appropriate vibration aging equipment according to the workpiece they want to age. For example, if the workpiece is within 15 tons, K2 equipment should be selected, rather than the larger the better. If the workpiece is smaller and a larger exciter is chosen, it will be a big horse pulling a small car, which not only wastes electricity but also shortens the service life of the equipment. At the same time, excessive excitation force may damage the structural performance of the workpiece, causing premature cracking and other phenomena.

The tonnage of the aging process is not the same. For example, K2's equipment can theoretically process workpieces up to 20 tons, but if the volume of the workpiece being aged is relatively large, such as a length of 15 meters or more, even if the workpiece reaches 20 tons or more, or even 30 tons, K2's equipment can still perform aging treatment on it, and the vibration force is still very strong.
