Abstract

The invention discloses an automatic steel wire shearing force checking device, which belongs to the technical field of steel wire detection, measurement and calibration. The device comprises a cabinet; the top of the cabinet is a working platform; a steel wire shearing mechanism, a steel wire supporting mechanism and a steel wire conveying mechanism are installed on the working platform; the steel wire shearing mechanism comprises a supporting frame body fixed to the working platform; a hydraulic cylinder with a piston rod vertically arranged downwards is installed on the supporting frame body; a movable blade is connected to the tail end of the piston rod through a pressure sensor; the steel wire supporting mechanism is located below the movable blade, a fixed blade matched with the movable blade is installed on the steel wire supporting mechanism, and the steel wire conveying mechanism is located on the steel wire input side of the steel wire supporting mechanism. Through the mutualcooperation of the steel wire shearing mechanism, the steel wire supporting mechanism and the steel wire conveying mechanism, the shearing force checking device of the test steel wire for the pliersshearing force test is realized.

Description

technical field [0001] The invention belongs to the technical field of steel wire detection, measurement and calibration, and in particular relates to an automatic calibration device for steel wire shear force. Background technique [0002] For the test of tongs, cutters and torsion cutters, the country has formulated the standard GB / T 6291-2013 "Test methods for torsos and cutters". In this method, in addition to the surface of the pliers, the In addition to the stipulations for test methods such as mouth gap, mouth top gap, clamping surface hardness and cutting edge hardness, it mainly specifies the test methods for bending strength test, shear performance test and torsion test of pliers. [0003] The patent literature about the pliers test mainly includes: Chinese patent authorization announcement number CN210221672U, which discloses a kind of pliers bending strength and shear performance test device, which belongs to the technical field of product quality detection and m...
