Compressive strength and deformation quantitative measurement equipment of foundry sand

摘要

(57) Abstract Objective Tamping the foundry sand with sample cylindrical internal, the sand sampleWhen it creates, regardless of the characteristics of the sand, always height of the sand sampleTo become identical, the compressive strength and the deformation tonnage the rightTry to be able to measure definite. Constitution Top aperture of sample cylindrical body 24 closed possible baseAnd making specified interval the said top aperture, the base which opposesThe test bench the piste of 35 which it has and the electromotive servo type cylinder 3Being installed in the Tip of nrotsudo 7, the above-mentioned sample cylindrical body 24Inside forming the device with the compressed head 19 which makes ascent and descent possibleTo do, the said sample cylindrical body 24 furthermore upper sample cylindrical body 24c, inIt consists with between section sample cylindrical body 24b and lower part sample cylindrical body 24aAs it does, the said intermediate section sample cylindrical body 24b is made swaggering unrestrictedru.
