In today's fast - paced industry, manufacturers face greater pressure to ensure their products are durable and safe for consumers. Accurate testing is crucial for assessing the impact resistance of products in sectors such as electronics, automotive, and construction. In this regard, the IK Vertical Hammer Impact Tester has emerged as an essential tool. This article delves into the comprehensive analysis the IK Vertical Hammer Impact Tester, like structure, composition, working principle, level choice, application and operation etc.

1. Overview of IK Vertical Hammer Impact Tester

The IK vertical hammer impact tester, also named as IK vertical hammer impact testing machine, is a device used to test the mechanical strength of lamp, housing of household and similar electrical appliances, etc.. The ik vertical Hammer impact tester is mainly designed based on the vertical impact test requirements of Test Ehc in the IEC60068-2-75 standard. The IK vertical impact hammer tester releases the hammer head through an electromagnet to ensure instantaneous release and vertical drop, and is easy to use.

2. Structure and Composition of the IK Vertical Hammer Impact Tester

2.1 Base

Firstly, the base of the IK vertical hammer impact tester is constructed to be extremely stable. It is typically made of heavy - duty materials such as thick - walled steel to withstand the reaction forces generated during the impact. Secondly, it’s used to place the sample, so the size of the base is not fixable, it can be customized according to the sample dimension.

2.2 Guide rail system

Next, ‌the IK vertical hammer impact tester uses a lifting device combined with a screw guide rail to adjust the drop height. Additionally, the length of the guide rail determines the drop height, which is easy to use‌.

2.3 Release Method

Then, the vertical hammer impact tester uses an electromagnet to release the impact hammer. This allows for instant release and vertical fall, cutting down friction and errors.

2.4 Guide Tube

Subsequently, the guide tube is made of stainless steel. Each impact hammer equips with one guide tube, so there are 5pcs guide tubes together with the impact device. Moreover, the height equals to the length of the impact hammer plus the falling height required by IEC60068-2-75. 

2.5 Features of the Impact Hammer

Finally, IK vertical impact test device is equipped with hammers of various energies. Specially, these energies include 2J, 5J, 10J, 20J and 50J, which are suitable for the mechanical strength testing needs of different products. In addition, the impact hammers are made of chrome-plated iron to ensure stable performance and accuracy after repeated use. And the dimensions and shape of the hammers are strictly designed according to IEC60068-2-75 figure A.2, A.3, A.4, A.5 and A.6.

3. Working Principle

According to the test Ehc Vertical hammer of IEC60068-2-75, the impact hammer falls freely from a certain height through the guide tube and hits the sample in the vertical direction.

4. Choice of Energy Level of IK Vertical Impact Testing Machine

The energy of impacts depends on the mass of the striking object and its speed, which may be generated by its fall. Normally, the ik vertical impact testing machine will be used only on accessible horizontal surfaces. Morever, it’s also used for testing the energy above 2J (Ik07). The energy and the relative height are indicated on the IEC60068-2-75 Table 2.

5. Application

The IK vertical impact hammer test apparatus is widely used to test the mechanical strength of the household appliances and electronic products.

5.1 Household appliances

The IK vertical hammer impact test device plays a crucial role in testing the mechanical strength of the housings of household appliances such as refrigerators, washing machines, and lamps. By subjecting these components to impact tests, it can effectively ensure their durability and safety during daily use. This helps to prevent potential damage or malfunction caused by accidental impacts in the home environment, providing users with reliable and long - lasting products. 

5.2 Electronic products:

For various electronic products like smartphones, tablets, and laptops, this test device is highly suitable for conducting mechanical strength tests on their housings. Through these tests, it can be determined whether the products can withstand the impacts they may encounter during transportation, such as jolts during shipping, and in - use situations, like accidental drops. This ensures that electronic products have sufficient impact resistance, protecting the internal components and maintaining the normal operation of the devices.

6. Simple Operation of the IK Vertical Impact Tester

First, place the sample on the base

Next, select the impact hammers and guide tubes according to the energy required to the test sample

Then, press the “Attract” button on the control box, and install the impact hammers and the guide tube at the bottom of the electromagnet

Subsequently, rotating the hand wheel to adjust the required fall height according to IEC60068-2-75.

Finally, press the “Release” button, the impact hammer will be released to hit the sample.

The IEC60068- 2-75 IK Vertical hammer Impact Tester is of great significance in the field of product quality evaluation and safety assessment. It is specifically designed to test the mechanical shock resistance of various products, especially electrical equipment enclosures. By subjecting products to well - defined vertical impact forces, manufacturers and researchers can accurately assess the durability and integrity of the items under test, ensuring their safe and reliable operation in real - world applications.
