Problems solved by technology

Ordinary grinding wheel products often use fine-grained, high-hardness formulas to resist spring deformation when processing ordinary springs. However, there are obvious defects when using ordinary grinding wheels to roughly grind automobile internal combustion engine springs: low grinding output, and grinding wheel dressing frequency High, low quality of spring surface processing, high rate of defective products

Embodiment Construction

[0008] The present invention will be further described below in conjunction with embodiment.

[0009] A special grinding wheel formula for rough grinding automobile internal combustion engine springs. Our formula design mainly considers the composition of abrasives and the ratio of binders. The following is the composition of abrasives and the ratio of binders:

[0010] Abrasive composition table (calculated based on the sum of all abrasive volume compositions being 100%)

[0011] Abrasive name Abrasive size % of total abrasive volume 45A F16 20 SSA F16 60 31C F24 20

[0012] Binder ratio table (calculated according to the weight percentage of the weight of each component in the weight of the abrasive)

[0013]

[0014] The grinding wheel manufactured according to the above grinding wheel formula can be heated and hardened according to the normal 24-hour grinding wheel hardening curve, and the surface product quality meets the relevant n...

Abstract

The invention discloses a formula of a grinding wheel special for roughly grinding an automobile internal combustion engine spring. The sum of the compositions of all the grinding materials is 100% byvolume, wherein the grinding material is composed of, by volume, 20% of 45A grinding material with the F16 granularity, 60% of SSA grinding material with the F16 granularity and 20% of 31C grinding material with the F24 granularity. According to further improvement, a binding agent is composed of, by weight, 12.5% of Y1 type resin powder, 4% of S6 type resin liquid, 0.5% of M accelerant, 2% of Benhancer, 3% of cryolite, 6% of gypsum powder and 15% of a pore-forming material. The formula of the grinding wheel special for roughly grinding the automobile internal combustion engine spring is high in grinding yield, low in grinding wheel dressing frequency, high in spring surface machining quality and low in reject rate.

Description

technical field [0001] The invention relates to the technical field of grinding wheels, in particular to a grinding wheel formula. Background technique [0002] The special spring for automobile internal combustion engine is a spring material with high temperature resistance and impact resistance. During the surface grinding process of the spring, the grinding wheel becomes a necessary processing tool. Due to the characteristics of the spring itself and its good tensile strength, it is easy to be deformed by force during processing, which puts forward higher requirements on the characteristics of the grinding wheel for processing it. Ordinary grinding wheel products often use fine-grained, high-hardness formulas to resist spring deformation when processing ordinary springs. However, there are obvious defects when using ordinary grinding wheels to roughly grind automobile internal combustion engine springs: low grinding output, and grinding wheel dressing frequency High, the...
