1, the instrument to achieve microcomputer automatic control. The special processing system is used to automatically collect dynamic signals, process and output data, and the instrument has the printing function to automatically record and lock the impact force peak.
2, the use of high-precision dynamic force sensor, measuring range 20KN.
3, the use of no magnetic leakage adsorption structure, drop hammer, piercing cone automatically locate the center of the helmet.
4, test head mold: special mold casting No. 1 and No. 2 and metal head mold, after the impact, can be repaired, much better than the old standard wooden head mold.
5, the whole machine adopts European standard aluminum profile, frame structure, stronger stability; The electric circuit adopts built-in type, beautiful structure, with modern science and technology sense and texture.
6, impact height: 1000mm±5mm; Height measurement is simple and intuitive, which greatly improves test efficiency and accuracy.
7, drop hammer and puncture hammer free replacement, simple operation.
8, protection system: the new design around the metal protective net and installation link fixed way, greatly reduce the possibility of accidents in the test, further improve the safety of the test operation.
9. The bottom is equipped with a level test device to ensure that the test is at a level and improve the test accuracy.
10, impact mode: the form of free fall, the real simulation of the actual use of the site, to avoid the guide rail or guided fall for complex speed compensation, to ensure the accuracy of the test.

The equipment has high degree of automation and easy operation, and is used in safety helmet production enterprises, major quality inspection units and construction engineering inspection stations.

1, the head mold: in line with GB/T 2812-2006 "Safety hat test Method" standard Appendix A provisions.
2, bench: can control the suspension and release impact drop hammer, puncture cone.
3, drop hammer: impact drop hammer: the mass is 5.0±0.01kg, the hammer head is hemisphical, the radius is 48mm, the material is 45# steel, the shape is symmetrical and uniform puncture cone: the mass is 3.0±0.01kg, the puncture part: the cone Angle is 60°, the cone tip radius is 0.5mm, the length is 40mm, the maximum diameter is 28mm, the hardness is HRC45.
4, force sensor: measuring range 0-20kN, frequency corresponding minimum 5kHz, dynamic force sensor, accurate to 1N.
5, base: with impact strength, can be firmly installed force sensor.
6, power display device: when the circuit forms a closed loop, it can send a signal to indicate that the puncture cone has contacted the head die.
7, drop hammer height: 1000mm±5mm.
8, 1#, 2# MG-Al alloy test head die each, the weight of the head die is 5.0kg±0.1kg, other dimensions and parameters in accordance with GB/T 2812-2006 Appendix A.
9. Working power supply: AC220V,50Hz.
