A kind of intergranular corrosion test bending method frock

Abstract

The utility model discloses an intergranular corrosion test bending method frock, including testing machine, press bending frock and upper pressure head. Press bending frock contains frock mesa, its upper end is connected two groups of support sliding table, and is equipped with press bending seat on the upper end of support sliding table, and the lower end of side edge is fixed rack piece, and the lower end of mesa is penetrated with driving shaft and driven shaft, and the first gear and second gear are fixed on the shaft respectively, and the end of driving shaft has adjusting handle, and the both sides of mesa are equipped with guide rod support and guide rod. Rotating adjusting handle, driving shaft drives rack piece through gear, makes both sides support sliding table synchronous reverse movement, and guide rod and sliding groove ensure the moving accuracy, realize the accurate alignment of support center and upper pressure head. The semicircular smooth surface of press bending seat avoids sample grinding. This frock solves the problem of big traditional manual adjustment error and low efficiency, and the support spacing adjustment error is less than or equal to 0.1mm, and is convenient to operate, is applicable to different specifications sample, and improves intergranular corrosion test precision and efficiency.
