Electric Hammer Durability Impact Test Apparatus For Electric Tools
IEC 60745-2
Product Information For Electric Hammer Durability Impact Test
Apparatus:
Standard: IEC 60745-2-1: Particular requirements for drills and
impact drills, clause 17; IEC 60745-2-6: Particular requirements
for hammers, clause 17 and figure 103.
Application: This apparatus is applicable to durability test for
hand held motor operated
electric tools power no more than 2.5KW.
Test sample: Electric hammers, Electric drills and impact drills
Feature: The test apparatus in according with IEC 607465-2-6 figure
103 requirements, load hammer or drill, intermittent operate it,
check whether electrical or mechanical hazard appears during the
normal use of the electric hammer or drill.
Equipment components are as follows:
1, electric control cabinet containing PLC, 7 Inch Touch screen,
control panel, load (voltage 0-250V adjustable, voltage and current
display);
2, mechanical device as shown in Figure 103, containing 360
kilograms of steel base, including the impact head, steel plate and
fixture.
Test Functions For Electric Hammer Durability Impact Test
Apparatus:
1. No load test: All hammers, including hammers with drill only mode, are mounted
vertically in a test apparatus as shown in Figure 103 and are
operated at 1.1 times rated voltage for 12h, then operated at 0.9
times rated voltage for 12h. Each cycle comprising a period of
operation of 30s and a rest period of 90s during which the tool
remains switched off. During test, on each test voltage, hammer
placed in three different directions (horizontal, vertical,
vertical), each position of the tool running time of about 4 hours.
2. Load test: All hammers, including hammers with drill only mode, are mounted
vertically in a test apparatus as shown in Figure 103 and are
operated at rated voltage or at the mean value of the rated voltage
range, for four periods of 6h each, the interval between these
periods being at least 30 min.
During these tests, hammers are operated intermittently, each cycle
comprising a period of operation of 30s and a rest period of 90s
during which the tool remains switched off.
During the tests, an axial force to ensure steady operation of the
impact mechanism is applied to the hammer through a resilient
medium.
If the temperature rise of any part of the tool exceeds the
temperature rise determined during the test of 12.1, forced cooling
or rest periods are applied, the rest period being excluded from
the specified operating time.
