Specification

JB-B  series Semi automatic impact testing machine

Product Description: JB-B 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

JB-B the types of testing machine operation for the electric control box and a half automatic control impact testing machine, the swing hammer impact of potential energy and the impact of the remaining on the dial of the potential difference, to get the specimen of the absorbed energy, simple operation, high work efficiency, thrust the specimen in the profit with residual energy automatic Yang pendulum, ready to do the next impact test, so in for impact testing laboratory and do a lot of impact test of metallurgy, machinery manufacturing plant and other departments can embody its superiority.

Main feature

◆Significant advantages of electrical control section

1.  integrated circuit board, maintenance is more simple.

2.  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 mechanical parts

1.  the advanced host structure technology design, the host base and column using a new design and packaging, beautiful appearance, solid and durable, reasonable structure.

2. the high rigidity of the pendulum rod to prevent the pendulum impact after the shaking of the sample.

3. the use of standard turbine reducer, high efficiency, completely avoid the transmission failure.

4. modular structure, reducing the processing and assembly process, the host accuracy is greatly improved.

5.  using the photoelectric proximity switch instead of the old-fashioned mechanical limit switch, improve the stability of the equipment, the angle of the pre - lift is constant.

◆ Significant advantages of security

With high toughness materials of 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, to ensure safety
