Abstract

The invention discloses a metal liquid filling type flow regime viewer which can be used for directly observing the cast metal liquid filling type state. The viewer is composed of an endoscope 1, a steel tube 2, a limiting clamp 3, a signal transmission line 4, a computer 5 and a die 6. The endoscope 1 is arranged in the steel tube 2, the steel tube 2 is pre-buried in the die 6, the limiting clamp 3 is clamped at one end of the steel tube 2, one end of the signal transmission line 4 penetrates through the limiting clamp 3 to be connected with the endoscope 1, and the other end of the signal transmission line 4 is connected with the computer 5. By means of the viewer, the filling type flow state when metal liquid leaves an ingate can be directly observed, reasonability of the design of a pouring system is determined, and the pouring system is optimized by adjusting parameters and the structure of the pouring system so as to enable the metal liquid filling process to reach an ideal state and overcome casting defects generated by unreasonable design of the pouring system; the viewer can be used for direct observation, is more reliable than computer simulation, safer and more convenient to use than an X-ray observation filling process, and the viewer is simple in structure and low in use cost.

Description

[0001] Technical field [0002] The invention is a casting technology field, which is specifically involved in a metal liquid charging darkee. This observer can directly observe the device of the metal liquid charging state during the pouring process. Background technique [0003] Casting is one of the basic craftsmanship of the modern machinery manufacturing industry, and its development marks the production strength of a country.The design of the pouring system is an important part of the production of high -quality castings. The rationality of the pouring system is directly related to the quality of the casting.The role of the pouring system is to deliver metal fluid smoothly to make it full of cavity within the specified time. At the same time, it can prevent the slag and other residues from entering the cavity, and minimize the secondary oxidation of the metal solution as much as possible to obtain high -quality castingsEssenceInappropriate pouring systems will cause flaws s...
