Abstract
The invention relates to a method for trimming a fluoroplastic-coated rubber sealing ring. The method comprises the following steps of: machining a hole in a lathe, wherein the diameter of the hole is 0.1mm smaller than the outer diameter of a component, and the depth of the hole does not exceed the size of small rubber diameter of the component, so that a cutter of the lathe can conveniently deepen into the hole to operate; when an inner hole of the lathe has a rough edge, regulating a small cutter holder to be an angle of 45 DEG, mounting a sharp lathe cutter, starting the lathe, slowly feeding the small cutter holder, and turning the inner rough edge; and when turning an outer rough edge, just moving a support plate outwards, slowly regulating the positions of a cutter tip and the component to enable the cutter tip to be tangent with the component. The fluoroplastic-coated rubber sealing ring trimmed by the method disclosed by the invention has smooth appearance without polishing trace, and high machining efficiency, and is very suitable for mass-production.
Description
Technical field
The invention belongs to mechanical manufacturing field, particularly a kind of trimming method that coats the fluoroplastics rubber seal.
Background technology
Coat fluoroplastics rubber seal (hereinafter to be referred as bag fluorine cushion rubber) and be and be used for fluorine plastic film and when cushion rubber vulcanizes, be bonded in the cushion rubber working surface and form.It has also that coefficient of friction is little, wearability reaches good advantages such as self lubricity well except that keeping the rubber ring primary characteristic, be applicable to movable sealing.Bag fluorine cushion rubber all has demand on all kinds of types, have a good application prospect, and its suitable condition of work (medium, temperature, pressure) is decided by to be coated the performance of sizing material.But because there is certain degree of difficulty aborning in bag fluorine cushion rubber, qualification rate is lower, because the part that suppresses need carry out deburring, unnecessary sizing material and film burr is removed.Common deburring mode is to adopt sharp blade or the sand rod reaming of polishing gently.With the deburring of sand rod, the sand rod wants the split pattern place to polish, and the rubber face in the bruting process around the die joint is also polished, and is not bright state; Use the blade deburring, the situation that can avoid die joint to be polished, but polytetrafluoroethylene film limit indentation influences presentation quality.
Summary of the invention
The technical problem that the present invention will solve provides the trimming method of the also high coating fluoroplastics rubber seal of a kind of not only production efficiency height and qualification rate.
A kind of trimming method that coats the fluoroplastics rubber seal, this method is: hole with the slightly little 0.1mm of part external diameter of processing on lathe, hole depth surpasses the size in the little glue of part footpath, be convenient to lathe tool deeply and operate; During car endoporus burr, small tool is adjusted into 45, loads onto sharp and sharp lathe tool, start lathe, slowly with the small tool feed, burr in the turning; During the outer burr of turning, only need middle supporting plate is outwards moved, slowly the position that regulates point of a knife and part makes itself and part tangent again.
The coating fluoroplastics rubber seal overall appearance that adopts above-mentioned trimming method to process is smooth, does not have the vestige of polishing, and working (machining) efficiency is high, is applicable to very much production in enormous quantities.
Description of drawings
Fig. 1 is the structural representation of the outer burr of trimming method turning of the present invention;
Fig. 2 is the structural representation of burr in the trimming method turning of the present invention;
The specific embodiment
Coat fluoroplastics rubber seal (being called for short bag fluorine cushion rubber) and be and be used for fluorine plastic film and when cushion rubber vulcanizes, be bonded in the cushion rubber working surface and form.The structure that coats the fluoroplastics rubber seal is divided into outer two kinds of cushion rubber and the interior coating cushion rubbers that coat according to the difference of service condition, is respectively WF (outsourcing fluorine cushion rubber) and NF (interior bag fluorine cushion rubber).
Coating the fluoroplastics rubber seal is formed by following materials processing:
1) fluoroplastics: undefined term polytetrafluoroethylene film SFM-2 or SFM-3, should meet the regulation of SG-187-80 " polytetrafluoroethylene film ", HB5821-83 coats fluoroplastics " O " type rubber seal technical conditions.Its thickness is generally 0.1mm～0.2mm, or presses the pattern regulation.
2) rubber: acrylonitrile-butadiene rubber is pressed the regulation of HG6-407-79 " aircraft industry rubber part and section bar are used sizing material ", HG6-878-76 " special-purpose sizing material " or other relevant acrylonitrile-butadiene rubber standards.
3) glue: should be JQ-1 " isocyanate glue ".
Coat and have unnecessary sizing material and film burr after the fluoroplastics rubber seal suppresses out, use conventional methods deburring, presentation quality is very undesirable.
The present invention considers with lathe the unnecessary burr of part to be cleared up, to satisfy the appearance requirement of part according to the principle of turning oil seal lip.Through test of many times, this method has obtained obvious effects, has reached good deburring quality.Concrete processing method is following:
Like Fig. 1, shown in Figure 2, on lathe, process a hole with the slightly little 0.1mm of part external diameter, hole depth surpasses the size in the little glue of part footpath, be convenient to lathe tool deeply and operation; During car endoporus burr, small tool is adjusted into 45, loads onto sharp and sharp lathe tool, start lathe, slowly with the small tool feed, burr in the turning; During the outer burr of turning, only need middle supporting plate is outwards moved, slowly the position that regulates point of a knife and part makes itself and part tangent again, just can obtain the effect of satisfaction.
Adopt the overall appearance smooth of the coating fluoroplastics rubber seal that the present invention processes, bad cutter trades such as no bubble, eyelet, impurity, concavo-convex, scuffing, the generation of corrugationless situation.
Claims (1)
