Problems solved by technology

However, due to the backwardness of the testing methods for the impact resistance of diamond composite sheets, the actual state of the diamond composite sheet working in the mine is quite different from the state of the impact toughness test, which seriously restricts the research on the impact performance of the diamond composite sheet

Abstract

The invention discloses an impact resistance test device for a diamond compound sheet. The impact resistance test device comprises a guide pillar, a top plate and a base plate, wherein the top plate and the base plate are fixedly arranged at two ends of the guide pillar; a cylinder is arranged on the top plate; a clamp is arranged on the base plate; a pneumatic chuck is arranged at the front end of a piston rod of the cylinder; a hammer is arranged in the pneumatic chuck; the hammer is corresponding to the clamp; and a punching ball is arranged at the front end of the hammer. The impact resistance test device for the diamond compound sheet is simple in structure and convenient in operation; a percussion drilling wave theory is utilized to simulate the practical stressed state of the diamond compound sheet during the underground working process; the edge part of the diamond compound sheet is punched gradually by the punching ball; an impact value which is obtained when a sample surface is cracked or broken is taken as a quantitative index for measuring the impact resistance of the diamond compound sheet; the degree of automation is high; and the measuring precision is high.

Description

technical field [0001] The invention belongs to the technical field of measuring equipment for impact resistance of superhard materials, and in particular relates to a diamond composite sheet impact resistance test device for measuring the impact toughness of diamond composite sheets used for oil and natural gas drilling. Background technique [0002] At present, diamond compact (PDC) has been widely used in rotary drill bits due to its excellent wear resistance, but its impact toughness is poor. In recent years, people have devoted themselves to improving the impact resistance of diamond compacts, in order to seek to apply them to impact-containing rock-breaking tools (such as pick teeth). However, due to the backwardness of the testing methods for the impact resistance of the diamond composite sheet, the actual state of the diamond composite sheet working in the mine is quite different from the state of the impact toughness test, which seriously restricts the research on t...
