What is the use of a spring impact hammer?

Spring impact hammer, also known as spring impactor, is a kind of collision test instrument that releases a certain amount of impact energy through the built-in impactor and makes it act on the surface of the sample.

The spring impact hammer is made according to the international standard IEC60068-2-75 and the domestic standard GB2423.55 in Figure E.1 (spring hammer test device), which is widely used to test the ability of the shell, lever, handle, knob, indicator light and other shells of household and similar electrical products to withstand mechanical impact.

Spring impact hammer follows the IK grade classification, from IK01 to IK07 can be tested by spring impact hammer, different IK grades correspond to different impact energy, IK01 corresponds to 0.14J impact energy, IK02 corresponds to 0.2J impact energy, IK03 corresponds to 0.35J impact energy, IK04 corresponds to 0.5J impact energy, IK05 corresponds to 0.7J impact energy, IK06 corresponds to 1J impact energy, and IK07 corresponds to 2J impact energy.

The hammerhead used in the 2J spring impact hammer needs to use stainless steel, and the hammerhead of the spring impact hammer below 1J and 1J is made of polyximide, so in terms of price, the 2J spring impact hammer is a little more expensive than the spring impact hammer below 1J and 1J, and the weight is also a little heavier.

A spring impact hammer with only one gear is called a single-gear spring impact hammer, because there is also a multi-gear spring impact hammer, the multi-gear spring impact hammer is divided into a five-gear spring impact hammer and a six-gear spring impact hammer, and the five gears of the fifth gear are IK02, IK04, IK04, IK05, IK06; The gears in the six gears are IK01, IK02, IK04, IK04, IK05, IK06. The multi-speed spring impact hammer can be switched according to different levels of energy according to the needs and then released.

In addition, the single-gear spring impact hammer uses a 1mm thick aluminum alloy shell, while the multi-gear spring impact hammer uses a 2mm thick stainless steel shell, and the durability of the latter is much higher than the former.

Finally, let's talk about the use of the spring impact hammer: fix the specimen according to the relevant standards, select the impact energy and test position, pull the operating handle of the impactor until the "click" sound, the impactor is in a ready state, the impactor is vertically facing the surface of the sample and in contact with it, pushing the impactor to release it, and the impact test of the sample.
