Vibration stress removal machine aging vibration meter

Equipment Introduction:

Vibration aging equipment, aging vibration meter, and welding stress relief equipment are devices that place a motor system (exciter) with an eccentric weight on a workpiece using fixtures and support the workpiece with elastic objects such as rubber pads. Start the motor through the host control and adjust its speed to make the workpiece in resonance state. Generally, the residual stress of the workpiece can be adjusted by vibration treatment for 15-30 minutes.

Scope of application:

The dynamic aging machine is suitable for stress relief of castings, forgings, welded parts, and machined parts made of carbon structural steel, low-alloy steel, stainless steel, cast iron, non-ferrous metals (copper, aluminum, zinc, and their alloys), and other materials.

Currently used in the marketVibration stress removal machineThey are mainly controlled by microcontrollers, with the model being 89C51. It is a microcomputer that integrates a microprocessor, a certain capacity of RAM and ROM, as well as I/O ports, timers, and other circuits on a single chip. The 89C51 integrates a 4 KB FLASH ROM, with a total of 5 interrupt sources. A two digit hexadecimal number can represent 256 storage units. atVibration aging instrumentThe application on the platform has the advantages of simple use, high reliability, and good real-time performance, but it also has disadvantages such as difficulty in porting and lack of necessary technical support, especially unlike commercial embedded systems that are widely used and continuously researched and updated. Therefore, our company's technical personnel have decided to develop a more technical and reliable control system, using PLC control.

Essentially,Time sensitive vibration instrumentThe use of PLC control is actually a pre made 51 microcontroller system.

But PLC also has its own characteristics: PLC widely uses ladder diagrams instead of computer language, which has certain advantages in programming vibration aging machine programs. You can understand ladder diagrams as being similar to calculator languages such as assembly, but with a different scope of use! And the usual practice is for PLC software to convert your ladder diagram into C or assembly language, and then use assembly or C compilation system to compile it into machine code. PLC only runs machine code. A ladder diagram can makeVibration aging machineUsers are more likely to get started with the operation.
