Shear strength and deformation quantitative measurement equipment of foundry sand

摘要

(57) Abstract Objective Shear strength and deformation tonnage of foundry sand easy andThe device which can be measured accurately is offered. Constitution Upper sample cylindrical body 6c and intermediate section sample cylindrical body 6bAs and lower part sample cylindrical body 6a is superposed, the intermediate sectionTo make sample cylindrical body 6b swaggering unrestricted, the electromotive servo type cylinderTo try to push the edge strip of intermediate section sample cylindrical body 6b with 11, electricityIn piston rod 15 Tip of dynamic servo type cylinder 11 addingThrough pressure head 27, to install the load electrolysis cell 28, said rodoseru sa in 28 and the electromotive servo type cylinder 11The encoder 31 which detects the rotary tonnage of bomota 13You joint to XY plotter 46.
