The wearable steel ball for grinding, disclosed by the invention, has excellent grinding efficiency and long service life.
Description
Technical field
The present invention relates to grinding machinery technical field, relate in particular to a kind of grinding abrasion-proof steel ball.
Background technology
Ball mill is one of widely used Super-fine grinder machinery in industrial production.Ball mill steel ball is ball mill equipment grinding material medium, by the collision friction between ball mill steel ball, between steel ball and material, produces ablation, is important base parts and components, and especially accurate industrial ball plays great function in the national economic development.The usage quantity of abrasion-proof steel ball on market is very huge, the abrasion-proof steel ball using in prior art is generally spherical steel ball, in motion process, can only clash into and grind in the mode of a contact, efficiency is lower, simultaneously, in process of lapping, the violent friction producing due to collision makes abrasion-proof steel ball top layer be easy to damage, shortens the service life of abrasion-proof steel ball.
Summary of the invention
In order to solve the technical problem existing in background technology, the present invention proposes a kind of grinding abrasion-proof steel ball, realized the abrasive dust operation in ball mill, it has good grinding efficiency, long service life.
A kind of grinding abrasion-proof steel ball that the present invention proposes, comprise steel ball body, described steel ball body is that spheroid and its ellipticity are less than 0.05, the top layer of described steel ball body is provided with a plurality of projections and convexes to form two interrupted banded structures, wherein, article one, interrupted banded structure is parallel to the major axis of described steel ball body and the minor axis that another interrupted banded structure is parallel to described steel ball body, is provided with to run through its chamber and the lower surface of this chamber is waveform in projection; Described steel ball body comprises wear-resistant coating and steel matrix, wear-resistant coating and steel matrix form layer structure from outside to inside, described wear-resistant coating is that hydrocarbon layer and the employing material vapour deposition mode of noncrystalline shape forms, and described wear-resistant coating has the hole that runs through its thickness direction.
In technique scheme, steel ball body is designed to spheroid, simultaneously, at this surface layer of steel ball, be provided with projection, make in steel ball working process, by the mode of a contact, change micro-contact into and contact with line, increased grinding area, therefore, increased the shock surface of steel ball, thereby increased the stress surface of material, simultaneously, bossing has larger pressure when broken material, has further promoted grinding efficiency; By chamber is set in projection, and the lower surface of chamber is designed to waveform, can, so that projection is worn to chamber place, relies on the lower surface of chamber to continue the frictional force that keeps larger, thereby maintain high grinding efficiency; The existence of wear-resistant coating can improve the anti-wear performance of steel ball, meanwhile, the hole that runs through wear-resistant coating thickness direction is set in wear-resistant coating, can keep the grinding capacity of wear-resistant coating, promotes the grinding efficiency of steel ball.
Preferably, the upper surface of described protruding middle chamber is the curved surface towards described protruding top bending.
Preferably, the thickness of described wear-resistant coating is 30-40 μ m.
Preferably, the quantity of described projection is 12-16.
Preferably, the ellipticity of described steel ball body is 0.02-0.04.
In the present invention, by the shape of steel ball and structure are optimized, improve the grinding efficiency of steel ball, and made steel ball there is longer service life.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation grinding with abrasion-proof steel ball that the present invention proposes;
Fig. 2 is the schematic cross-section of Fig. 1 middle chamber;
Fig. 3 is the schematic cross-section of Fig. 1.
The specific embodiment
As shown in Figure 1, Fig. 1 is a kind of structural representation grinding with abrasion-proof steel ball that the present invention proposes; Fig. 2 is the schematic cross-section of Fig. 1 middle chamber; Fig. 3 is the schematic cross-section of Fig. 1.
With reference to Fig. 1-3, in a kind of specific embodiment that the present invention proposes, a kind of grinding abrasion-proof steel ball, comprise steel ball body 1, steel ball body 1 is that spheroid and its ellipticity are 0.03, and the top layer of steel ball body 1 is provided with 14 projections 2 and projection 2 forms two interrupted banded structures, wherein, article one, interrupted banded structure is parallel to the major axis of steel ball body 1 and the minor axis that another interrupted banded structure is parallel to steel ball body 1, and projection is provided with in 2 and runs through its chamber 3 and the lower surface of this chamber 3 is waveform; Steel ball body 1 comprises wear-resistant coating 4 and steel matrix 5, wear-resistant coating 4 forms layer structure from outside to inside with steel matrix 5, wear-resistant coating 4 is for the hydrocarbon layer of noncrystalline shape and adopt material vapour deposition mode to form, the thickness of wear-resistant coating 4 is 35 μ m, and wear-resistant coating 4 has the hole that runs through its thickness direction.
In the present embodiment, steel ball body 1 is designed to spheroid, simultaneously, on steel ball body 1 top layer, be provided with projection 2, make in steel ball working process, by the mode of a contact, change micro-contact into and contact with line, increased grinding area, therefore, increased the shock surface of steel ball, thereby increased the stress surface of material, simultaneously, projection 2 parts have larger pressure when broken material, have further promoted grinding efficiency; By in projection 2, chamber 3 being set, and the lower surface of chamber 3 is designed to waveform, can, so that projection 2 is worn to chamber 3 places, relies on the lower surface of chamber 3 to continue the frictional force that keeps larger, thereby maintain high grinding efficiency; The existence of wear-resistant coating 4 can improve the anti-wear performance of steel ball, meanwhile, the hole that runs through wear-resistant coating 4 thickness directions is set in wear-resistant coating 4, can keep the grinding capacity of wear-resistant coating 4, promotes the grinding efficiency of steel ball.
