Jinan Limei Electromechanical Technology Co., Ltd. specializes in the production and sales of vibration aging equipment, stress relief equipment, stress detection equipment, ultrasonic impact equipment, ultrasonic flaw detection equipment, etc. The product technology is independently developed by our company's technical personnel, and through extensive experimentation and innovation, we have gradually built products with independent intellectual property rights, which have received high praise from customers in the industry. At present, our company has been regarded as a recommended brand by a large number of application manufacturers in professional fields such as civil air defense engineering, explosion-proof electrical appliances, mining equipment, and machine tool manufacturing.

During welding, casting, and mechanical processing, uneven local heating of the workpiece can cause significant residual stress. The presence of stress can affect the accuracy stability of the workpiece or cause local cracking. If the local stress of the casting is too high, it will change with the machining process during rough machining. Even if the processing is completed, there may still be unstable accuracy after a few days of storage.

Methods for eliminating stress: Currently, the most commonly used methods on the market are heating stress relief and vibration aging devices Stress relief, as well as ultrasonic impact stress relief, although natural placement stress relief is effective, the cycle is too long, as short as six months, which no manufacturer can afford. Time is money. Heating in a tempering furnace results in a stress relief rate of80%Left and right, but will be affected by the following aspects.

1Transporting workpieces that are too large is a problem

2Large workpieces generally have higher stress relief costs, which increase production costs and reduce the cost-effectiveness of the product.

3I don't have a tempering furnace myself, so I need to take it to a specialized heat treatment plant. In order to improve efficiency, the processing plant does not really keep the insulation for such a long time (usually24This may cause secondary stress or have no effect at all.

4Some stainless steel and other materials do not allow heating to relieve stress

Vibration aging instrument Stress relief is achieved by using a specially designed vibration machine to induce resonance in the entire workpiece. During the resonance process, the workpiece emits a buzzing sound and feels a certain amount of vibration when touched. Maintaining this resonance state for a period of time will relax the residual stress inside the workpiece and gradually restore the balance of the distorted lattice. The stress relief rate is30%-60%There are several advantages to using vibration to relieve stress:

1Not limited by the size, dimension, or shape of the workpiece.

2The devices are all mobile and can be moved to different locations for use

3The period of stress relief is short, generally10A workpiece weighing around one ton can be vibrated for one hour

4The cost of stress relief is low, and the power consumption of vibration aging machines is very small. The motor power of the exciter configured on the market is mostly highThe numbers are in1200W左右。

5It can be repeatedly vibrated to relieve stress. For example, many precision machine tools first remove the lower stress when processing raw parts, and then perform rough machining on the machine tool. During the rough machining process, cutting stress is generated, and a vibration aging instrument is used Remove it before precision machining, which can better ensure the accuracy and stability of the workpiece

Vibration stress relief equipment is widely used in aerospace, oil drilling, mining machinery, papermaking machinery, packaging machinery, printing machinery, textile machinery, shearing and bending machines, CNC machine tools, casting processing, and more. Due to its good stress relief effect, it has gained recognition from a large number of users.
