Embodiment

[0054] In the initial state, the pendulum 51 is in a vertically drooping state, the zero-degree mark of the index plate 241 is aligned with the tooth groove of the index plate cover 242, and the clutch 31 is in a disengaged state.

[0055] Clamp the test piece: adjust the predetermined position of the clamping seat 61 on the frame splint 121, fix the clamping seat 61 on the frame splint 121 through the bolt 611; fix the movable wedge 621 through the screw 64 to clamp the metal test piece 7;.

[0056] Swing: Rotate the indexing plate cover 242 to align the tooth grooves with the predetermined angles on the indexing plate 241, tighten the positioning bolts 2421, so that the relative position of the indexing plate 241 and the indexing plate cover 242 is fixed ; Move the operating handle 34 of the clutch 31 to make the clutch 31 in the engaged state; start the motor 41, the main shaft 25 drives the index plate 241, the index plate cover 242, the pendulum and the clutch 31 to rotat...

Abstract

The invention relates to a breaking tester, in particular to a tester for researching a metal breaking mechanism. The tester consists of six parts, namely a rack, a main shaft device, a pendulum device, a clutch device, a power lifting device and a test piece clamping device. The metal breaking tester is mainly used for researching the brittle fracture performance of a metal material damaged under the conditions of different impact power, different hammer head shapes, different clamping modes, different impact positions, different metal test piece thicknesses and the like and further researching the metal breaking mechanism. The metal breaking tester has a simple structure, is safe and reliable, acts flexibly and is convenient to operate.

Description

technical field [0001] The invention relates to a testing machine, in particular to a testing machine for studying the crushing mechanism of light and thin metal materials. Background technique [0002] With the rapid growth of the national economy and the continuous improvement of people's living standards, automobiles and large household appliances have become people's daily necessities. While their renewal speed is accelerating, a large number of scrapped cars and large household appliances have also been produced. Today, when resources are extremely consumed and increasingly scarce, it is of great significance to do a good job in the recycling and recycling of scrapped cars and scrapped large household appliances for environmental protection, energy conservation and sustainable economic development. However, at present, the recycling of scrap metal from scrapped cars is generally done manually in my country, which has problems such as high labor intensity, low operation ...
