Abstract
The utility model provides a slewing roller, wherein a chromium coating is arranged at the surface of a slewing roller basal body, and the outer surface of the chromium coasting is provided with a convex-concave layer. According to the utility model, texturing is not carried out on the roller surface basal body which is high in hardness, and the roller surface roughness is realized through the loose hole of the chrome coating of the roller surface. The slewing roller meets the technical requirements of common enterprises, and the problems of the even roller surfaces of the dead angles of a shot blasting surface and the like and the difficulties of high production cost and longer production period are solved.
Description
Technical field
The utility model relates to a kind of slewing rollers.
Background technology
The technology of roll surface texturing utilization at present has bead and laser roughening process etc. techniques, and wherein laser roughening is handled equipment needed thereby costliness and production cost costliness, and the decay of roll surface roughness is very fast, and reality seldom utilizes its technology to realize in producing.Existing slewing rollers matrix 1 roll surface has convex-concave layer, and there is chromium coating 2 on the convex-concave layer surface.In process, what usefulness was prolonged in roll surface texturing (convex-concave layer) processing always is through the roll surface matrix being carried out bead, make to turn to the roll surface matrix to produce greater than R
Z3.2 roughness, on the roll surface matrix, carry out hard chrome plating then, the roughness of utilizing matrix and the uniformity that is deposited on the chromium layer thickness on the matrix guarantee the roughness of roll surface, reach the roughness that roll surface turns to requirement.The working roll that utilizes this process route to produce, very high to the bead requirement, and production cost is high, the production cycle is long; And exist poor repeatability, texturing roughness to be limited in scope, to exist problems such as shot-peening dead angle.From the slewing rollers instructions for use; The roll surface hardness that needs is more than 55 HRC, and concerning the bead operation, it is very uneconomic on the roll surface of this hardness, carrying out shot-peening texturing processing; And can accomplish this hardness the roll surface texturing professional production merchant seldom; This just causes the manufacturer production excessive cycle of this operation of external coordination, and delivery period is produced in influence, and production cost is comparatively expensive.
Summary of the invention
The goal of the invention of the utility model is to overcome the above-mentioned deficiency of prior art and a kind of easy to manufacture, technology is succinct, cost is low slewing rollers is provided.
The technical scheme of the utility model is: there is a chromium coating on the surface of slewing rollers matrix, and the outer surface of chromium coating has convex-concave layer.
Porose hole on the said convex-concave layer.
The utility model need not realized roll surface texturing effect through the bead of costliness.The utility model does not carry out texturing to the roll surface matrix of high rigidity, and realizes the roll surface roughness through roll surface chromium layer porosity.The utility model has been realized the specification requirement that general enterprise can reach, the uneven problems of roll surface such as shot-peening face dead angle that existed when having solved existing slewing rollers texturing treatment process, and production cost high with long difficult problem of production cycle.
Description of drawings
The embodiment that will combine accompanying drawing to provide below further details the utility model.
Fig. 1 is the structural representation of existing slewing rollers.
Fig. 2 is the structural representation of the utility model.
Among the figure, 1, the slewing rollers matrix, 2, chromium coating, 3, Kong Keng.
The specific embodiment
Among Fig. 2, on the surface of slewing rollers matrix 1 chromium coating 2 is arranged, the outer surface of chromium coating 2 has not of uniform size, hole, variform porosity hole 3.The utility model utilizes the roll surface hard chromium layers to carry out porosity and handles; Cause the fine holes hole 3 of roll surface chromium layer; Utilize these holes, hole 3 to realize the roughness that slewing rollers turn to friction to need; Thereby reach the requirement that slewing rollers transmit steering moment, can avoid present cloudburst treatment art to realize the existing problems such as shot-peening dead angle and expensive that leave of roll surface roughness.
Claims (2)
1. slewing rollers, it is characterized in that: on the surface of slewing rollers matrix (1) chromium coating (2) is arranged, the outer surface of chromium coating (2) has convex-concave layer.
2. slewing rollers according to claim 1 is characterized in that: on the said convex-concave layer porose hole (3).
