Description

Casting included angle grinding process
Technical Field
The invention relates to the technical field of casting surface treatment, in particular to a casting included angle grinding process.
Background
Casting is a method in which liquid metal is cast into a casting cavity that conforms to the shape of a part, and after it is cooled and solidified, a part or a blank is obtained.
After the blank is cooled and is subjected to subsequent processing means such as grinding and the like, the obtained object with certain shape, size and performance is the casting part required by people. In the process, the grinding process usually adopts a mechanical grinding mode or a shot blasting grinding mode. The cast parts obtained by the grinding modes have high surface roughness, and most importantly, the included angle is not easy to grind if the cast parts have included angles, and the included angle cannot be ground at all if the included angle is small.
Disclosure of Invention
The invention aims to provide a casting included angle grinding process to solve the technical problem.
In order to solve the technical problems, the invention adopts the following technical scheme:
a casting included angle grinding process is characterized by comprising the following steps:
(1) placing the casting in a closed box body for polishing, and suspending the casting in the middle of the box body;
(2) regulating the temperature in the box body to 65 ℃, preserving the temperature for 20min to enable the surface of the casting to be in a high-energy state, and then reducing the temperature in the box body to 45 ℃;
(3) and spraying high-pressure polishing liquid into the box body, wherein the polishing liquid is sprayed to the casting from 6 directions of the casting from the upper, lower, left, right, front and back, and the surface of the casting is polished by using the high-pressure polishing liquid, and the polishing liquid contains quartz sand.
As a further preferable technical scheme, in the grinding process in the step (3), the casting continuously rotates. As a further preferable technical scheme, the high-pressure polishing liquid is sprayed out through a high-pressure spray head, and the spraying angle of the high-pressure spray head is in cyclic reciprocating rotation between 0 and 120 degrees.
As a further preferable technical scheme, the polishing solution is a cutting solution as a carrier, quartz sand particles are blended into the cutting solution, the quartz sand particles are sprayed on the surface of a casting by a high-pressure and high-speed liquid flow, the surface of the casting is polished, and the mass ratio of the quartz sand particles to the cutting solution is 2: 83, the particle size of the quartz sand particles is 5-250 microns.
The invention has the beneficial effects that:
the invention provides a casting included angle polishing process, which can comprehensively polish castings with included angles, has no polishing dead angle, and can polish even included angles with very small angles in time; and the surface of the cast member polished by the method is smooth, and the polishing quality is high.
