Abstract
The present invention discloses the simple production process of slide bearing with integral PTFE lining. The production process includes the following steps: making shaft sleeve blank based on the requirement precision of slide bearing; cutting PTFE plate to form the PTFE blank with the aperture and length determined based on the slide bearing product; fixing the PTFE blank onto the end of a mandrel in the diameter smaller than the inner hole of shaft sleeve blank or inside the shaft sleeve blank bore port, and heating and extruding the mandrel with the PTFE blank to draw to the shaft sleeve blank bore; cooling the workpiece; machining the shaft sleeve blank on the mandrel and pushing out the mandrel, or machining the shaft sleeve blank after pushing out the mandrel to obtain the finished product.
Description
Technical field
The present invention relates to the manufacturing of sliding bearing, relate in particular to a kind of method of integrated adhesive inner lining of the PTFE of using made sliding bearing.
Background technique
It is the principal item of fluoroplastic that teflon is called for short PTFE.Because its chemical product is functional, friction factor is low, can at high temperature use continuously, therefore is used as antifriction material widely and uses.Because teflon hardness is low, generally could use in addition attached to the metal material surface that certain degree of hardness is arranged.Making sliding bearing with teflon at present is teflon to be fixed with tackiness agent on the sheet metal surface, make compound plate, then according to the specification blanking of sliding bearing, sliding bearing is processed in volume circle, shaping, can only be processed into the sliding bearing of band opening in this way, dimensional accuracy is wayward, and work efficiency is low, just can't make for the sliding bearing that some wall thickness are big.
Summary of the invention
The object of the present invention is to provide the manufacture method of simple, the astomous PTFE integrated adhesive inner lining type slide bearing of a kind of technology.
In order to achieve the above object, the manufacture method of integrated type PTFE sliding bearing is: make the axle sleeve blank according to requirement precision of slide bearing; With the plate cutting of PTFE, PTFE blank shape size is determined according to the aperture and the length of slide bearing product; The PTFE blank is fixed on diameter less than the plug end face of axle sleeve blank endoporus or be placed on the axle sleeve blank bore, and related PTFE blank pushes together with plug under the operating mode of heating, pull and stretch is in the endoporus of axle sleeve blank; Work-piece cools; Process axle sleeve blank end face and/or axle sleeve blank cylindrical after the compacting together with plug, eject plug then, perhaps eject axle sleeve blank end face and/or axle sleeve blank cylindrical after the processing compacting behind the plug.
Making the PTFE integrated adhesive inner lining type slide bearing according to the method described above, is to utilize extruding and pull and stretch principle that the sheet material of PTFE is fitted in the endoporus of axle sleeve blank bearing matrix and the equal imperforation of PTFE liner, the dimensional accuracy height of endoporus, good stability, and simplified technology, reduced cost.

Embodiment
The invention will be further described below in conjunction with accompanying drawing.
Make axle sleeve blank 1 as shown in Figure 1 according to the PTFE requirement precision of slide bearing, coated with adhesive in axle sleeve blank endoporus.In the middle of the plate cutting of PTFE become with holes 2 PTFE blank 3 as shown in Figure 2, the diameter in hole 2 is less than the external diameter of plug 4.The boundary dimension of PTFE blank 3 is determined according to the size of slide bearing product.The PTFE blank 3 that will have hole 2 is fixed on the end face of diameter less than the plug 3 of axle sleeve blank 1 diameter of bore, as shown in Figure 3 by pressing plate 5 and screw 6.For PTFE blank 3 is entered in the endoporus of axle sleeve blank 1 smoothly and equably, be pressed into bull nose 8 of end what the inner orifice of axle sleeve blank 1 fell filleted corner 7 and plug 3 in the extruding and the process of pull and stretch.With axle sleeve blank 1, PTFE blank 3 and plug 4 under the operating mode that is heated to 295 ℃ or 300 ℃ or 305 ℃ or 310 ℃ or 320 ℃ etc., plug 4 related PTFE blanks 3 are pushed together, pull and stretch is in the endoporus of axle sleeve blank 1, as shown in Figure 4.Treat work-piece cools, end face and/or cylindrical together with the axle sleeve blank 1 after the plug 4 processing compactings eject plug 4 then, perhaps eject the end face and/or the cylindrical of the axle sleeve blank 1 after plug 4 back processing are suppressed.Become the finished product of PTFE integrated adhesive inner lining type slide bearing as shown in Figure 5 at last.
Can not be shaped on hole 2 according to above-mentioned principle in the centre of PTFE blank 3 yet, also PTFE blank 3 is fixed on the end face of plug 4 without pressing plate 5 and screw 6, as long as PTFE blank 3 is put into the aperture of axle sleeve blank 1, under the operating mode of heating, plug 4 related PTFE blanks 3 are pushed together, pull and stretch is in the endoporus of axle sleeve blank 1.
