JB-W series Microcomputer controlled impact testing machine
Product name：JB-W series Microcomputer controlled impact testing machine
Product introduction
JB-W type impact testing machine for determination of metal materials under dynamic load, impact resistant performance, in order to determine whether the materials in dynamic load properties. The testing machine according to the national standard GB/T3808-2002< swing hammer impact testing machine test > development and production, according to the national standard GB/T229-2007< metallic materials Charpy pendulum impact hammer test method > impact test of metallic materials, the cross-section of the sample has a larger impact energy for 10 x 10 mm; testing machine, so mainly for impact toughness test larger black metal, such as steel and alloy
Product details
Mean value and Yang automatic test JB-W this type of machine for microcomputer control pendulum impact testing machine, using PC microcomputer and high reliability of the PLC controller to control the test process, electric Yang pendulum impact, the microcomputer measurement, calculation, display and print, work efficiency is high, the precision is high. The impact specimen by residual energy Yang pendulum, ready to do the next impact tests. In the continuous impact test test room and do a lot of impact test of metallurgy, machinery manufacturing and other departments to reflect its superiority. It can display material impact absorbing energy, impact toughness and pendulum angle test, print test reports. According to user requirements also can realize remote data transmission.
Main feature
◆Significant advantages of software and operating systems
1. the microcomputer and the dial at the same time display, data synchronization, equipped with a dual operating system, both through the computer mouse operation, but also can be used to operate the controller button box, do not interfere with each other, flexible operation, high efficiency.
2. can be continuous hundreds of specimens of continuous testing, manual operation just as by placing the specimen and press the action button, all the rest of the work is testing machine automatic completion, reduce labor intensity, the complete elimination of artificial data recording error probability, is particularly suitable to be used in a large number of samples of metallurgical mining industry.
3. select special functions abundant swing hammer impact testing software can automatically record the test results to the database for storing and searching operations. Software is running in the Win7, consistent user interface with windows style Chinese Windows system. Arranging and the fetching, return pin, shock, put test operation are can be completed on the computer screen to input or mouse click.
◆Significant advantages of electrical control section
1. to import the PLC controller as the core of the electrical control system, using high precision photoelectric encoder as the angle acquisition sensor.
2. integrated circuit board, maintenance is more simple.
3. using the brush clutch to replace the old clutch, the test, the pendulum automatic take place, the clutch is effectively protected, reduce the system to the clutch tooth damage, prolong the system life.
◆ Significant advantages of security
Use of high toughness materials semi closed door cover contains the pendulum the orbit, and also prevent being washed off the sample spatter wounding, maximize avoid misoperation brought to the operating personnel injury, ensure safety.
