Description

Technical Field

[0001] The invention relates to the field of casting processing, and in particular to a rust removal device and method for an investment casting water glass casting. Background Art

[0002] Castings are metal shaped objects obtained by various casting methods, that is, the smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods. After cooling and subsequent processing such as grinding, the resulting object has a certain shape, size and performance. After the preliminary processing is completed, it needs to be placed to eliminate the internal stress before subsequent work can be carried out.

[0044] The implementation principle of the embodiment of the present application is:

[0045] Before producing the finished casting, the two sides of the casting are fixedly connected with clamps and then installed on the clamping ring 16. Through the operation of the electric slide rail 12, the clamps on both sides are brought close to each other to achieve clamping and fixing. The door 03 is closed and opened, and the circulation pump 04 and the shot peening machine 05 are started. The shot peening machine 05 drives the balls with high-pressure gas, and then sprays them through the guide pipe 11, the swing plate 23 and the injection pipe 24 to achieve shot peening and rust removal. The ejected balls hit the casting, and then fall on the separation plate 21 under the action of gravity, contact the acid, and then clean the rust on its surface.

[0047] When rust removal is in progress, the water pump 32 is turned on synchronously, so that the water in the water tank 22 enters the filter box 20 through the suction pipe 33 and the water delivery pipe 34 for filtration and interception, and then further enters the separation plate 21 through the upstream pipe 19 to clean the sphere. After the shot peening is done, liquid remains on the sphere, and then circulates and hits the casting with the shot peening, thereby reducing the dust generated during the impact and reducing internal pollution. The dust and water combine and re-enter the separation plate 21, and then drip for subsequent circulation.

[0048] After use, open the door 03, and move the casting through the electric slide rail 12 to facilitate subsequent retrieval. Then, according to needs, carry out subsequent work or clean the interior.
