Problems solved by technology

[0002] The temperature of the castings that have just been cast is very high. When exposed to the air, it is easy to react with oxygen in the air and be oxidized, forming a thicker oxide layer, which may even lead to serious decarburization on the surface of the casting, which will seriously deteriorate the surface quality and serviceability of the casting. life

Embodiment Construction

[0013] Such as figure 1 As shown, a casting anti-oxidation device includes a sand tank 100 located at the bottom and filled with sand 110. Above the sand tank 100, there are a plurality of covers 200 that are buckled on the sand and can be lifted up. Lift up the cover, put the cast casting on the sand directly under the cover, then put a burning wax block on the casting, use the temperature of the casting to ignite the burning wax block, then cover the cover, use the burning wax block The combustion exhausts the oxygen in the cover, so that the castings are cooled in an oxygen-free environment, avoiding the oxidation of the casting surface, the anti-oxidation effect is good, the surface quality of the castings is improved, and the service life of the castings is increased.

[0014] In this embodiment, all the covers 200 are arranged in a line along the length direction of the sand tank 100. There are brackets 300 erected at both ends of the sand tank 100, and a first crossbeam...

Abstract

The invention relates to a casting anti-oxidation device and method. The casting anti-oxidation device comprises a sand tank located on the lower portion and filled with sand, a plurality of cover bodies covering the sand and capable of being lifted upwards are arranged above the sand tank, the cover bodies are arranged linearly in the length direction of the sand tank, supports are erected at thetwo ends of the sand tank, and a first cross beam is transversely arranged between the upper ends of the two supports; and air cylinders corresponding to the cover bodies one to one are arranged on the first cross beam, and the driving ends of telescopic rods of the air cylinders are connected with the cover bodies. According to the casting anti-oxidation device, operation is easy, using is convenient, it can be ensured that a casting is cooled in an oxygen-free environment, the surface of the casting is prevented from being oxidized, the anti-oxidation effect is good, the casting surface quality is improved, and the service life of the casting is prolonged.

Description

technical field [0001] The invention relates to a casting anti-oxidation device and a method thereof. Background technique [0002] The temperature of the castings that have just been cast is very high, and they are easily oxidized by reacting with oxygen in the air when exposed to the air, forming a thicker oxide layer, and even leading to serious decarburization on the surface of the castings, which will seriously deteriorate the surface quality and serviceability of the castings. life. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide an anti-oxidation device and method for castings which are easy to use and have good anti-oxidation effect. [0004] The present invention adopts the following schemes: a casting anti-oxidation device, which includes a sand tank filled with sand at the lower part, and a plurality of covers that are buckled on the sand and can be lifted upwards are arranged above the sand tank. [0005]...
