Problems solved by technology

The quality of PDC has been greatly improved at present. Testing a sample may require hundreds of impacts to destroy the sample. It will be very cumbersome to manually control the impact of the hammer and record the number of impacts, the test efficiency is low, and the operator’s work is increased. Work intensity

Abstract

The invention discloses a PDC anti-impact toughness automatic detection device and relates to the field of testing the strength characteristic of solid materials through mechanical stress. The device comprises a machine frame, a lifting device and an impact device. The machine frame is provided with a rotary impact plate. The impact device comprises an energy base plate capable of vertically ascending and descending, and a lifting device used for lifting the energy base plate. The lower end face of the energy base plate is provided with a fixing element used for fixing a PDC. The device also comprises a left limiting device and a right limiting device which are identical in structure. The left limiting device comprises a two-dimensional sliding mechanism and a left limiting plate used for supporting the energy base plate, and the left limiting plate can vertically ascend and descend and move left and right through the two-dimensional sliding mechanism and is arranged on the machine frame. The automatic detection device has the advantages that point-to-point impact of the impact plate and the PDC can be guaranteed during testing, impact energy can be precisely adjusted, secondary impact can be prevented, the automation degree is high, and testing results are precise and reliable.

Description

technical field [0001] The invention relates to the field of testing the strength properties of solid materials with mechanical stress, and more specifically relates to an automatic testing device for PDC impact toughness. Background technique [0002] Polycrystalline Diamond Compact (hereinafter referred to as PDC) is a new type of functional material, which is sintered with diamond micropowder and cemented carbide substrate under ultra-high pressure and high temperature conditions. It has both the high hardness and high wear resistance of diamond. It has the strength and impact toughness of cemented carbide, and is an ideal material for manufacturing cutting tools, drilling bits and other wear-resistant tools. The evaluation of PDC performance mainly includes wear resistance, impact toughness, and heat resistance, of which impact toughness is an important indicator to measure the quality of PDC. At present, the impact toughness testing of PDC mostly adopts impact testing ...
