Metal Charpy Impact Testing Machine 300 J Price /Impact Tester/Laboratory Equipment

Product DescriptionJBW-300B Computer Control Automnatic Metal Charpy Impact Testing Machine 300 j

Brief Introduction

JBW-300 computer control impact testing machine is ideal testing equipment , it is used to measure the metal material to resist impact loads under the dynamic properties. It can meet GB/T229-2007 <>, JJG 145-2007<>, ASTME23<> requirements.

This machine can automatically control for taking pendulum, impact and put off pendulum. And dual- display mode. ( dial display mode and computer display mode)

Features

1.This machine is low temperature impact testing machine, Equipped with pneumatic sample feeding device, make sure that the impact test can be carried out within 4 seconds , after the low temperature test of the specimen.So that can improve test precision and efficiency.
2.Sample cooling, constant temperature, temperature regulation, take pendulum, swing, send sample, positioning, impact are automatic control, automatic completion.
3.This machine is equipped with a computer and a printer. Can edit date and generate test report ,;storage and print the test date;average energy of the three test;test time and any other content. Can also realize the data remote transmission, the computer screen displays the cooling and cooling curve in real time, which is convenient for mastering the cooling time of the sample.
4.The main body of the machine is made of cast steel, so that it is rigid and stable in the whole test process, has strong impact resistance, is not easy to deform, the test result is accurate, and the service life is long
Structure introduction
Main component:
Host Frame; low temperature device, feeding mechanism, positioning mechanism, electric control box, computer, etc.
1.Host
Include :The body, the transmission mechanism, indicating mechanism, pendulum, automatic swing signal device
1)Mechanics Parts
Press the "take" button,Pendulum raise and hang up. Press the"automatic feeding" button,The machine will realize:Send sample→positioning→clamp→Sample in place,Then press the "pin" button, finally press"impact" button, that is a complete impact test .After the specimen is broken,Pendulum automatic raise and hang up for the next test.
2)Indicating mechanism
Include :dial scale, Pointer and Hand setting
This machine is controlled by microcomputer, which contains two sets of reading system. The test results are displayed on the computer at the same time
3)Pendulum section
Include :Pendulum,Blade,Swing rod,Joint,Plug,hook etc.
2.Cryogenic device:
It mainly consists of two parts: the refrigeration system and the low temperature tank.
Turn on the power supply and switch,High temperature compressor starts working,When reached the start condition of the low temperature compressor (about 5 minutes),then it will automatic starting,The refrigeration system enters the formal refrigeration working state.When the temperature is close to the set temperature,The heating device in the cooling tank begins to supply heat according to the PID regulation mode,In order to balance the cooling capacity of the cooling system, so that can realize constant temperature.
3.Feeding mechanism
Pneumatic feeding mechanism is mainly composed of two parts: cylinder and feeding device.You can fine tune the position and speed of the feed rod by adjusting the position of the magnetic switch.
4.Positioning mechanism
The specimen must be attached to the side of the anvil so that the specimen notch is correctly positioned at the center of the pendulum axis.This is guaranteed by positioning mechanism.
5.Electric control system
The electric control system of this machine is the SIEMENS PLC microprocessor control system which is developed by our company
