Embodiment 1

[0038] Embodiment 1, a method for manufacturing a silicon carbide grinding bucket in a grinding device, comprising the following steps:

[0039] 1), ingredients

[0040] Add silicon carbide to the reaction catalyst and additives, add water while stirring, and stir evenly. The weight ratio of the various components is:

[0041] 65 parts of silicon carbide, 5 parts of reaction catalyst, 10 parts of additive; appropriate amount of water;

[0042] Silicon carbide, reaction catalysts and additives are compounded in granular powder, the size of the particles is between 2 microns and 150 microns, the main component of the reaction catalyst is carbon powder, and the main components of the additives are polyvinyl alcohol and dipropylene glycol Alcohol, according to the amount of water added, the material after batching can be made into slurry or powder.

[0043] 2. Blank molding

[0044] Use the mold to produce the blank of the silicon carbide grinding bucket of the corresponding s...

Embodiment 2

[0056]Embodiment 2, in step 1 of above-mentioned embodiment 1, the proportioning of described various component weights can also be: silicon carbide 75 parts, reaction catalyst 15 parts, additive 30 parts; 1 is the same.

Embodiment 3

[0057] Example 3, in the step 1 of the above-mentioned example 1, the weight ratio of the various components is: 70 parts of silicon carbide, 10 parts of reaction catalyst, 20 parts of additives; appropriate amount of water. Other processing steps are identical with embodiment 1.

Abstract

The invention discloses a manufacturing method for a silicon carbide grinding barrel in grinding equipment. The manufacturing method comprises the following steps of firstly, batching: adding a reaction catalyst and an additive into silicon carbide, adding water while stirring and uniformly stirring to form slurry or powdery materials; secondly, molding a biscuit: producing the slurry or powdery materials into the biscuit of the silicon carbide grinding barrel with the corresponding specification and size by adopting a die through molding by slip casting or isostatic pressing molding; thirdly, drying, repairing and sintering the biscuit: drying the biscuit, repairing the dried biscuit, feeding the repaired biscuit into a vacuum furnace and adding a silicon alloy for sintering; fourthly, performing finish machining: mounting the sintered silicon carbide grinding barrel on a numeric control machining center for finish machining. The silicon carbide grinding barrel produced by the manufacturing method disclosed by the invention has the advantages of excellent wear-resistance performance, high hardness, high size precision and long service life.

Description

technical field [0001] The invention relates to a method for manufacturing a silicon carbide grinding barrel in grinding equipment, and belongs to the technical field of silicon carbide products. Background technique [0002] The grinding machine is suitable for deburring, derusting, rounding and bright polishing of various parts of metal, non-ferrous metal and non-metal products. It is especially suitable for surface finishing of deformable workpieces. The parts after finishing by this type of grinding machine not only maintain the original shape and position accuracy, but also improve the surface roughness of the parts by 1-2 grades. [0003] The grinding cylinder is an important component of the grinding machine. The grinding cylinders that appear on the market are usually made of stainless steel surface nitriding, but the service life of this grinding cylinder is short, and various metal ions will pollute the material, powder If the body color turns gray or black, the p...
