Abstract
The utility model discloses a modular wear resistant steel section, including the steel section body and the wear -resisting body of a plurality of ring form, steel section body has cylindric matrix part and two hemisphere portions that are located the matrix part both ends respectively, hemisphere portion and the coaxial setting of matrix part, and the radius of hemisphere portion is less than the matrix part radius, wear -resisting internal footpath equals the matrix part external diameter, and the matrix part periphery is provided with the external screw thread, and each wear -resisting internal zhou jun is provided with the internal thread with matrix part matching the external screw, each wear -resisting body all closes the mode suit soon through the screw thread and is (0.9 -1.1) in matrix part periphery, the width sum and the comparing of matrix part length of each wear -resisting body: 1, from the matrix part middle section to the both ends direction, the width of the wear -resisting body is the grow gradually. The utility model discloses a modular wear resistant steel section, its material yield rate is high, and resources conservation nature is good.
Description
Technical field
This utility model relates to grinding machinery technical field, particularly relates to a kind of Combined type wear-resisting steel section.
Background technology
Ball mill is one of widely used Super-fine grinder machinery in commercial production.Ball mill steel section is ball mill equipment grinding material medium, produces ablation by the collision friction between ball mill steel section, between steel section and material, is important base parts and components, and especially accurate industrial ball plays great function in the national economic development.According to data and practice have shown that, in mill Jie's steel section fatigue loss, the damage (such as small spot corrosion, the damage of burn into surface fatigue and plastic deformation etc.) on its top layer of steel section is in the great majority.And, steel segment table layer may wear to after to a certain degree, it may occur that metallic object is deposited in ball mill.These metallic objects do not play ore grinding effect substantially.Accumulation over time, these metallic objects occupy effective ore grinding space gradually, make the pack completeness of effective milling medium decline, it is necessary to be swapped out by metallic object, cause the waste of resource.
Utility model content
In order to solve the technical problem existed in background technology, the utility model proposes a kind of Combined type wear-resisting steel section, it is achieved that the abrasive dust operation in ball mill, its material yield rate is high, and resources conservation is good.
A kind of Combined type wear-resisting steel section that the utility model proposes, including steel section body and some circular wear body, steel section body has columned matrix part and two semi-spherical portion laying respectively at matrix part two ends；Semi-spherical portion and matrix part are coaxially disposed, and the radius of semi-spherical portion is less than matrix part radius；Wear body internal diameter is equal to matrix part external diameter, and matrix part periphery is provided with external screw thread, and each wear body inner circumferential is provided with the female thread coordinated with matrix part external screw thread；Each wear body is sleeved on matrix part periphery each through threaded engagement mode, and the width sum of each wear body and matrix part length ratio are (0.9-1.1): 1；From matrix part stage casing to direction of both ends, the width of wear body becomes larger.
In technique scheme, steel section is designed as the combining form of steel section body and wear body, by parts based on steel section body, using wear body as wearing terrain；Wear body is designed as circular, and wear body is set in the way of threaded engagement on steel section body, such that it is able to carry out the replacing of wear body and the recovery of steel section body, and facilitate views with high abrasion resisting material making wear body, thus promoting service life and the economy of steel section；According to combinations thereof construction features, by the version that steel section body design is cylindric matrix part and semi-spherical portion, matrix part is as the region installing wear body, by the radius of design semi-spherical portion less than matrix part radius, the abrasion that in steel section use procedure, matrix part is subject to can be reduced, thus promoting the response rate of steel section body；The width of wear body is designed, in conjunction with the abrasion condition of steel section in use different parts, the wear body of different in width is arranged on diverse location, advantageously reduce the percentage of damage of wear body, promote the service life of steel section.
Preferably, the quantity of wear body is 4-8.
Preferably, the width sum of each wear body and matrix part length ratio are 1.05:1.
Preferably, the radius of semi-spherical portion is (0.8-0.95) with the ratio of matrix part radius: 1.
In this utility model, by the shape of steel section and structure are optimized, improve the parts recuperability of steel section, such that it is able to effectively save resource.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of Combined type wear-resisting steel section that the utility model proposes.
Detailed description of the invention
As it is shown in figure 1, the structural representation that Fig. 1 is a kind of Combined type wear-resisting steel section that the utility model proposes.
With reference to Fig. 1, in a kind of specific embodiment that the utility model proposes, a kind of Combined type wear-resisting steel section, circular wear body 2 including steel section body 1 and three groups of different in width, often organizing circular wear body 2 and include two identical circular wear body 2, steel section body 1 has columned matrix part and two semi-spherical portion laying respectively at matrix part two ends；Semi-spherical portion and matrix part are coaxially disposed, and the radius of semi-spherical portion is 0.9:1 with matrix part radius ratio；Wear body 2 internal diameter is equal to matrix part external diameter, and matrix part periphery is provided with external screw thread, and six wear body 2 inner circumferentials are provided with the female thread coordinated with matrix part external screw thread；Six wear body 2 are sleeved on matrix part periphery each through threaded engagement mode, and the width sum of six wear body 2 and matrix part length ratio are 1.05:1；From matrix part stage casing to direction of both ends, the width of wear body 2 becomes larger.
The above; it is only this utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; any those familiar with the art is in the technical scope that this utility model discloses; conceive according to the technical solution of the utility model and utility model thereof and be equal to replacement or change, all should be encompassed within protection domain of the present utility model.
