Abstract
The invention discloses a method for manufacturing a composite shaft sleeve with two tapered ends. The method is divided into two manufacturing technologies according to different forms of raw materials of products and includes a method for manufacturing the composite shaft sleeve from short plates and a method for manufacturing the composite shaft sleeve from coiled strips. The method is characterized in that the method for manufacturing the composite shaft sleeve from the short plates is applicable to manufacturing the products on a small scale and includes sleeving a shaft sleeve to be machined on a taper shaping mandrel and jointly feeding the shaft sleeve and the taper shaping mandrel through a shaping die under the effect of pressure; the method for manufacturing the composite shaft sleeve from the coiled strips is applicable to manufacturing the products on a large scale and includes rolling the strips by the aid of a cylindrical roll and a roll in the simulated shape of an inner hole of the composite shaft sleeve with the two tapered ends so as to obtain certain strips. Each certain strip has a thick middle, two thin edges and a trapezoidal section. The method has the advantages that high forming pressure for squeezing the products in automatic forming dies in later procedures can be omitted, the production efficiency is high, and the products are good in friction and wear properties and stable in size.
Description
Technical field
The present invention relates to a kind of manufacture method of sliding bearing, relate in particular to the manufacture method of a kind of two ends band tapering composite shaft sleeve.
Background technology
Three layers of general composite slide axle sleeve (or claiming three layers of compound oil-free lubrication axle sleeve), the processing method adopting for by " with the plastics of modified Teflon antifriction layer--bronze--steel backing three layers be combined into self-lubricating plate material " by machined or blanking punched one-tenth fritter sheet material, then roll into axle sleeve, pass through again shaping, planar end surface chamfering, clean, the operation such as zinc-plated processes, because axle sleeve is at trimming, what adopt is that axle sleeve integral body is pressed into after annular shaping mould, with one or both ends, with the cylindrical shaping core rod leading, pass through inner hole of shaft sleeve again, then axle sleeve is extruded from annular shaping mould, so made axle sleeve surfaces externally and internally is all the face of cylinder, wall thickness is even.But product in use, particularly in some occasions that endwisely slips, when bearing bears larger radial load, the surface of axle is not exclusively fitted on the inner hole wall of axle sleeve, the axis of axle sleeve and the axis of axle journal are not parallel, and only contact with the fraction region (comprising chamfering mouth) at axle sleeve two ends, cause so on the one hand the pressure that bear axle sleeve part to become rapidly large, thereby make axle sleeve occur eccentric wear, greatly reduce service life, chamfering mouth place at axle sleeve is machining chamfering because of what adopt on the other hand, generally all there is the effect of machining sclerosis in chamfering mouth place, long-term and axle sliding-contact, axle surface can be pulled, cause friction pair to lose efficacy, this phenomenon is especially obvious in the larger occasion that endwisely slips of radial load.
Summary of the invention
The object of the present invention is to provide that a kind of production technology is simple, low cost of manufacture, production efficiency are high, steady quality, the manufacture method of two ends band tapering composite shaft sleeve that can mass large-scale production.
In order to achieve the above object, the manufacture method of two ends band tapering composite shaft sleeve has following two kinds, is respectively by sheet material (general length is less than 2 meters) manufacture method and coiled strip manufacture method.Described two ends band tapering composite shaft sleeve is to have open seam, in the middle of two ends orifice diameter is greater than, is the round sleeve of bell mouth shape.
Manufacture method with sheet material: plastics--bronze--steel backing with modified Teflon antifriction layer, is combined into three-layer composite self-lubricating sheet material according to existing method-→ blanking-→ cut and highly roll up circle-→ shaping internal-and external diameter-→ shaping tapering-→ planar end surface chamfering-→ clean-→ check-→ finished product packing warehouse-in, described shaping tapering operation is with the shaping of tapering shaping core rod: tapering shaping core rod front end used is guide section, it after guide section, is shaping active section, the shape of its shaping active section is identical with the concaveconvex shape of two ends band tapering composite shaft sleeve endoporus, it after shaping active section, is the mandrel shank with limited step, in shaping tapering operation, two ends band tapering composite shaft sleeve to be processed is enclosed within on the shaping active section of tapering shaping core rod, axle sleeve is passed through to shaping mould together with tapering shaping core rod under the effect of pressure, axle sleeve is by the extruding of tapering shaping core rod and shaping mould, form the horn mouth at two ends, aperture, and utilize open seam that axle sleeve is deviate from from tapering shaping core rod.
Use coiled strip manufacture method: plastics--bronze--steel backing with modified Teflon antifriction layer, is combined into three-layer self lubricating coiled strip according to existing method-→ unreel-→ itemize-→ rolling tapering-→-→ plane width--→ axle sleeve automatic moulding is put in storage in → cleaning-→ check-by → finished product packing to dig inside and outside chamfering; Described rolling tapering: be to use a pair roller rolling, the roll surface of one of them roll is cylindrical, the roll surface of another roll is the indent roll of hole shape in the band tapering composite shaft sleeve of imitative two ends, to there is the surface of plastics in the face of indent roll, band is carried out to rolling, and obtaining thin cross section, thick middle both sides is trapezoidal billot.
Between cleaning and inspection process, also have the zinc-plated operation of sleeve outer surface.
Above-mentioned two kinds of manufacture methods have the advantages such as technology stability is good, good product quality, especially use coiled strip manufacture method, and production efficiency is high, is more suitable for the consecutive production operation in streamline.
