The invention discloses a wire cutting device for manufacturing a cylindrical joint test piece. The device comprises a lower base, wherein a bracket and a pressure spring component are arranged on the lower base; the bracket comprises a vertical arm connected with the base and a horizontal arm connected with the vertical arm; a reciprocating motor component and a driving gear component are arranged in the horizontal arm of the bracket; the reciprocating motor component is connected with an adjustable emery rope component through a piston, and an adjustor is arranged at the other end of the adjustable emery rope component; the driving gear component is matched with an adjustable-speed motor; a bearing rotary table is arranged at the top of the pressure spring component. According to the device, the requirements of numerous test pieces, low disturbance, low discreteness and the like of a joint test piece mechanical property test can be met, and the basic support is provided for ensuring systematic researches on the mechanical properties of the joint test piece.
Description
technical field [0001] The invention relates to a sample making device, in particular to a wire cutting device for making a cylindrical joint test piece. Background technique [0002] Joints, layers, fissures, schistoses, cleavage planes and other IV and V structural planes in the rock mass will destroy the integrity of the rock mass and affect its physical and mechanical properties, while the occurrence, trace length, roughness, Geometric parameters such as connectivity and filling are important factors affecting the mechanical properties of jointed rock mass, and are also the focus of existing experimental research. The structure of joint specimens is complex, and the preparation of specimens that meet the requirements is an important link in the test process. The preparation of natural joint specimens has problems such as large disturbance, difficult to meet the demand, and low success rate of sample preparation; cutting joint specimens with blades in conventional sample...
