GL-JBDW-300Y -temperature impact testing machine, used to resist the impact of the performance of metal materials under dynamic load inspection, metallurgical machinery manufacturing units necessary testing equipment , but also research institutes new materials research indispensable test instrument .
According to ex -hung ball joint was informed , GL-JBDW-300Y is a computer screen automatic impact testing machine, using PC computer control , electric Yang pendulum , impact, computer measurement , computing , display and print the results , such as high efficiency high precision. After the impact of the sample can use the remaining energy automatic Yang put , do the next test preparation, easy operation, high work efficiency. In the continuous impact test laboratory and a lot to do impact testing metallurgy, machinery manufacturing and other industries to better reflect its superiority. PC can display material impact energy , toughness , Yang angle and pendulum test averages , and the average value when the second test print data and tests. GL-JBDW-300Y -type low-temperature impact testing machine cascade refrigeration compressor technology , the use of thermal equilibrium theory and loop mixing method to achieve uniform cooling of the sample to the automatic thermostat , temperature regulation are electrical automatic control, with dedicated send samples automatic feeding device , automatic face orientation sample , sample baked to ensure the impact of time of not more than two seconds , meet the requirements of low-temperature metal Charpy impact test method. the testing machine meets the national standard GB/T3808-2002 " pendulum impact testing machine test ", according to GB GB/T229-2007" metallic materials - Charpy pendulum impact test " impact test on metallic materials , and meet JJG145-82" pendulum impact testing machine test procedures .

Main features:
Low-temperature impact testing machine from the host machine , low temperature devices , sending and automatic feed mechanism consisting of positioning mechanism .
Cryogenic device: the low-temperature device is a company based GB/T229-2007 " metal Charpy pendulum impact test" required for cryogenic devices and the latest developed compressor refrigeration equipment. Using cascade refrigeration compressor technology , the use of thermal equilibrium theory and loop mixing method to achieve uniform cooling of the sample to the automatic thermostat , temperature indicators fully meet the national standards required . Cryogenic tank technology using single-chip microcomputer control , digital temperature, automatic temperature control, automatic timer , alarm , easy to operate security , cooling speed, large volume, high precision, low temperature impact testing of metallic materials is ideal sample cooling , insulation equipment .
Feeding mechanism : the sample was cooled to cryogenic device set temperature, the feeding mechanism can be quickly and reliably supporting surface of the sample to the jaw . Feed mechanism mainly consists of two parts feeding device , damping devices. Sports feed mechanism is composed of the motor pulley by size , friction plates , rack gear shaft spread , feeding the motor rotating rod , the rod quickly converted into feed forward feeding and backward linear motion reset . Feed gear fitted around the yoke , the movement of the rack , hit fork damping cylinder rod by means of a damping cylinder , and the rack gear is rotated by the forward resistance of the friction wheel by means of friction slip, reduced feed rate, into the sample to ensure a reliable feed lever jaw face and the right back position. Slip friction plate , to protect the device from damage , the longitudinal position of the adjusting nut , the spring pressure also change, change with the size of the frictional force , the feed can change the size of the thrust rod , the throttle valve adjusts the damping cylinder , change the discharge of oil , change the size of the damping force will change the feeding speed of the front and rear ends , the resistance cylinder compressor oil used in # 13 (or the same oil viscosities ) , plus the amount of oil should not be too small. The feed lever forward, reverse , stop, etc. are feeding rod hit piece compression stroke switch sends electrical signals to control the rotation of the motor to achieve. Adjust the position of the switch hit piece , you can fine-tune the position of the feed rod and stroke length .
Positioning mechanism : the sample must be close to the jaw side , so that the sample gap correctly located the center axis of the pendulum . Sample close to the side of the jaw , is guaranteed by the positioning mechanism . When the feed lever before samples sent by the holder , due to the action of the spring is fixed , the sample close to the side of the jaw forward movement , when the sample from the back end has not fixed spring , when the front end into the jaw surface feeding mechanism in the compression stroke the striker piece switch signals the solenoid action , then positioning mechanism in operation , the positioning mechanism of the positioning lever to the operating position , the positioning mechanism is pressed against the side of the elastic top column sample until the sample close to the distal end positioning mechanism positioning surface finish sample positioning work . When the feed lever spring compression (22mm ~ 3mm), solenoid signal is reset after re- positioning mechanism away from the sample , the positioning surface for impact . A positioning mechanism mounted integrally with the holder , and a spring pull solenoid driven positioning block reset , the next move , under the push of the spring screw , the screw is always positioned close to the surface , while the movable sleeve by a pin positioning mechanism driven by the side of the elastic top column rotation. Eccentric positioning mechanism to reduce the impact of inertia of the sample, so the sample can improve the positioning accuracy. |
