Description

Grinding disc for producing steel balls

Technical Field

The utility model belongs to the technical field of steel ball production and application, and particularly relates to a grinding disc for steel ball production.

Background

The steel ball is divided into grinding, forging and casting according to the production and processing technology. The steel is classified into bearing steel balls, stainless steel balls, carbon steel balls, copper bearing steel balls, alloy balls, and the like according to the material to be processed. The bearing steel ball is an important industrial basic part, and the alloy steel ball is a spherical iron alloy wear-resistant body which is generated by taking carbon, chromium, manganese, molybdenum and the like as main added metal elements and adopting forging, spinning, rolling, casting and other modes, and is the most important component part for crushing industrial mining balls, cement balls and the like at present.

The existing processing technology of the grinding steel ball mainly comprises cold heading forming, smooth grinding, heat treatment, hard grinding, primary grinding, passivation, fine grinding, cleaning and spin-drying, demagnetizing, alcohol cleaning and finished product forming. Wherein, in the process of primary grinding and lapping, mainly grind through the abrasive disc of two symmetry settings, the main semicircular in shape setting of grinding groove on the current abrasive disc, this kind of grinding groove though can reach the purpose of grinding, but its easy production gnaws, and then leads to the qualification rate to reduce.

SUMMERY OF THE UTILITY MODEL

Aiming at the technical problems of the grinding disc, the utility model provides the grinding disc for producing the steel balls, which has the advantages of reasonable design, simple structure, convenient processing and good grinding effect.

In order to achieve the purpose, the utility model adopts the technical scheme that the grinding disc for producing the steel balls comprises a grinding disc and a grinding ring arranged on the grinding disc, wherein a material port is arranged on the grinding disc, the grinding ring is cut by the material port to form a feeding end and a discharging end, and the grinding ring gradually changes from a 90-degree right-angled deviation groove to a 90-degree right-angled square groove from the feeding end to the discharging end.

Preferably, the grinding ring gradually changes from a 90-degree right-angle eccentric groove to a 90-degree right-angle square groove from the feeding end to the discharging end through a semicircular groove.

Compared with the prior art, the utility model has the advantages and positive effects that,

1. the utility model provides a grinding disc for producing steel balls, which improves the grinding efficiency and the grinding precision of the steel balls by utilizing 90-degree right-angle offset grooves, forms final plasticity on the shape of the steel balls by utilizing semicircular grooves, increases the wrapping surface of the steel balls by utilizing 90-degree right-angle square grooves, ensures that the steel balls are not easy to gnaw and finally improves the qualified rate of products.

Detailed Description

In order that the above objects, features and advantages of the present invention can be more clearly understood, the present invention will be further described with reference to the accompanying drawings and examples. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced otherwise than as specifically described herein and, therefore, the present invention is not limited to the specific embodiments disclosed in the following description.

Embodiment 1, as shown in fig. 1 to 4, this embodiment provides a grinding pan 1 for steel ball production, aim at improving grinding efficiency of grinding pan 1 and the rational rate of product, for this reason, what this embodiment provided includes grinding pan 1 and the grinding ring 2 of setting on grinding pan 1, grinding pan 1 is overall discoid to be set up, be provided with the grinding ring 2 of a plurality of intervals setting on grinding pan 1, set up the material mouth on grinding pan 1, the material mouth is for opening the square groove on the circumference of grinding pan 1, and like this, the material mouth cuts off grinding ring 2, and like this, the one end of grinding ring 2 forms feed end 21, and the other end forms discharge end 22, and it passes in and out the material at the material mouth promptly.

Above structure is the common structure of current abrasive disc 1, so in this embodiment, does not add the detailed description, and the key place of improving of this embodiment is to improve the unanimous slot of whole annular cross-section of tradition, makes it change according to the grinding state, and specifically speaking, grinding ring 2 is from feed end 21 to discharge end 22 direction by 90 off-normal cannelures to 90 square cannelures at right angle gradually. Change it into 90 degrees right angle partial groove, mainly consider that current abrasive disc 1 is two abrasive disc 1 about when the grinding, wherein, the cope match-plate pattern is the horizontal plate, like this, it changes 90 degrees right angle partial groove, and its initial stage grinding volume can increase to can improve grinding efficiency, through experimental discovery, for the grinding groove of half slot, its grinding efficiency has improved 35%.

The 90-degree right-angle square groove increases the wrapping surface of the steel ball, so that the steel ball is not easy to bite. Therefore, the yield of the steel balls coming out of the discharge end 22 is greatly improved, and the yield is improved by 5 to 8 percent through experiments.

In order to further improve the grinding effect, in the present embodiment, the grinding ring 2 gradually changes from the 90 ° right-angled eccentric groove to the 90 ° right-angled square groove through the semicircular groove from the feeding end 21 to the discharging end 22. The semicircular groove is a traditional groove-shaped structure, and the regularity of the shape of the steel ball can be effectively ensured, so that the change of the grinding ring 2 is gradually changed from a 90-degree right-angle eccentric groove to the semicircular groove, and finally the change is a 90-degree right-angle square groove.

Through the arrangement, the grinding efficiency and the finished product qualification rate of the steel balls are effectively improved, and the steel ball grinding device is suitable for large-scale popularization and use.

The above description is only a preferred embodiment of the present invention, and not intended to limit the present invention in other forms, and any person skilled in the art may apply the above modifications or changes to the equivalent embodiments with equivalent changes, without departing from the technical spirit of the present invention, and any simple modification, equivalent change and change made to the above embodiments according to the technical spirit of the present invention still belong to the protection scope of the technical spirit of the present invention.
