Abstract
The invention relates to a spring made of novel materials and a manufacture method thereof, and aims at providing a corrosion-resistant polytetrafluoro ethylene (PFA) spring and the manufacture method thereof. The PFA spring is made of PFA, and the manufacture method comprises the following procedures: 1 choosing a PFA tube with required tube diameter, and cutting the tube into sections with proper length; 2 fixing the cut PFA tube on a fixture, and cutting the tube into spiral strip shapes through a blade; 3 winding the spiral PFA strips on a sizing lead screw, placing the strips into an oven, setting the temperature to be 250 degrees and baking for 2 to 3 hours; and 4 taking the spiral PFA strips out from the oven, and placing the spiral PFA strips into pure water for cooling. Accordingly, the PFA spring is obtained.
Description
Technical field
The present invention relates to spring of a kind of plastics on new materials and preparation method thereof.
Background technique
Spring is a kind of mechanical parts that utilize elasticity to carry out work.Generally make with spring steel.Impact or shake, store up the size of energy, measuring force etc. in order to motion, the mitigation of controlling parts, be widely used in machine, instrument.The kind complexity of spring is various, divides by shape, mainly contains helical spring, spiral spring, leaf spring etc.
Spring uses in various occasion, and the metal spring on market can not use in corrosive liquids.If use metal spring in corrosive liquids, current way is on spring, to plate one deck corrosion-resistant coating, but coating very easily comes off, so operational safety is not high, spring has corroded but and can not find in time sometimes.
Summary of the invention
The object of the present invention is to provide a kind of PFA spring with corrosion resistance and preparation method thereof.
The technological scheme that realizes the object of the invention is:
A kind of PFA spring, is characterized in that: above-mentioned spring adopts PFA material.
The width a of above-mentioned spring is 3.5～4.5mm, and spacing b is 5～7mm.
A kind of PFA spring making method, has following steps:
1) select the PFA pipe of required caliber, and cut into suitable length;
2) the PFA pipe after cutting is fixed in frock, pipe cutting is become to strip-spiral with blade;
3) helical PFA bar is wrapped on sizing screw mandrel, puts into baking oven, 250 ℃ of setting temperatures, toast 2～3 hours;
4) from baking oven, take out helical PFA bar, put into purified water cooling, obtain PFA spring.
Above-mentioned steps 3) in sizing screw mandrel be that metal is made, the spacing of its groove is the spacing of made spring.
Benefit of the present invention is that PFA material has corrosion resistance, so when the spring of being made up of PFA pipe uses in corrosive liquids, also have good corrosion resistance, can guarantee that spring plays a role normally.
Accompanying drawing explanation
Fig. 1 is the perspective view of PFA spring of the present invention.
Embodiment
See Fig. 1, PFA spring of the present invention adopts PFA material.The width a of above-mentioned PFA spring is 3.5～4.5mm, and spacing b is 5～7mm.
Above-mentioned PFA spring making method, has following steps:
1) select the PFA pipe of required caliber, and cut into suitable length;
2) the PFA pipe after cutting is fixed in frock, pipe cutting is become to strip-spiral with blade;
3) helical PFA bar is wrapped on sizing screw mandrel, puts into baking oven, 250 ℃ of setting temperatures, toast 2～3 hours;
4) from baking oven, take out helical PFA bar, put into purified water cooling, obtain PFA spring.
Above-mentioned steps 3) in sizing screw mandrel be that metal is made, the spacing of its groove is the spacing of made spring.Be that PFA pipe completes after helical cutting, helical PFA bar screwed in to the groove location of metal screw mandrel, through baking oven heat-shaping, helical PFA bar will form required spring shape, and its spacing is consistent with sizing screw mandrel flute pitch.PFA spring through heating, cooling formation can be applied in corrosive liquids.
Obviously, above-mentioned embodiment of the present invention is only for example of the present invention is clearly described, and is not the restriction to embodiment of the present invention.For those of ordinary skill in the field, can also be easy on the basis of the above description make other pro forma variation or substitute, and these changes or alternative also by within being included in the definite protection domain of the present invention.
