Firmness detection device for machine-made sand molded product

Abstract

The invention relates to the technical field of machine-made sand, and discloses a firmness detection device for a machine-made sand molded product. The firmness detection device comprises a bracket,a support block is fixedly connected to the interior of the bracket, a support rod is movably connected to the interior of the support block, a main electromagnet is fixedly connected to the interiorof the bracket, a guide rod is sleeved with the main electromagnet, a limiting rod is movably connected to the outer portion of the guide rod, a limiting spring is movably connected to the outer portion of the limiting rod, a limiting magnetic block is fixedly connected to the outer portion of the limiting rod, a limiting electromagnet is movably connected to the outer portion of the limiting magnetic block, and the bottom of the guide rod is fixedly connected with a guide block. Through cooperative use of an electrode plate, an adjusting electromagnet, a movable block and an adjusting block,the effect of adjusting the impact force is achieved, the test range is further enlarged, the detection effect is improved, the accuracy of detection data is effectively guaranteed, and thus the quality safety of a machine-made sand molded product is guaranteed.

Description

technical field [0001] The invention relates to the technical field of machine-made sand, in particular to a firmness detection device for machine-made sand molding products. Background technique [0002] Machine-made sand refers to sand processed by sand making machines and other auxiliary equipment. The shape and size of the finished product are more standardized, and the performance is getting better and better. In modern municipal construction, machine-made sand is widely used, and machine-made sand is in use In the process, it is usually divided into direct use, or making finished products of machine-made sand and concrete first, and then using it in municipal construction, and because the firmness of machine-made sand is often worse than that of river sand, and in order to ensure the qualification of building materials In general, it is necessary to test the robustness of the finished product before use. [0003] However, the existing detection devices are not perfect...

AI Technical Summary

Problems solved by technology

[0003] However, the existing detection devices are not perfect, and the strength of the finished machine-made sand is often only detected by throwing or manual knocking. The detection equipment is also complicated in the detection process, the detection effect is single, and multiple multiple detections are required, which is time-consuming and laborious, and the detection cost is too high
