Embodiment Construction

[0010] See figure 1 , PFA spring of the present invention adopts PFA material. The width a of the above-mentioned PFA spring is 3.5-4.5 mm, and the distance b is 5-7 mm.

[0011] Above-mentioned PFA spring manufacture method has following steps:

[0012] 1) Select the PFA tube with the required diameter and cut it to a suitable length;

[0013] 2) Fix the cut PFA tube on the tooling, and cut the tube into spiral strips with a blade;

[0014] 3) Wrap the spiral PFA strip on the shaping screw, put it into the oven, set the temperature at 250°C, and bake for 2 to 3 hours;

[0015] 4) Take out the spiral PFA strip from the oven, put it into pure water to cool, and obtain the PFA spring.

[0016] The shaping screw rod in the above step 3) is made of metal, and the distance between the grooves is the distance between the produced springs. That is, after the spiral cutting of the PFA tube is completed, the spiral PFA strip is screwed into the groove of the wire rod for positioni...

Abstract

The invention relates to a spring of novel material and a production method thereof and aims to provide an anticorrosion PFA spring and a production method thereof. The PFA spring is made of PFA material. The production method includes the steps of 1, selecting a PFA tube with required diameter, and cutting the PFA tube to proper length; 2, fixing the cut PFA tube on a fixture, and cutting the tube into a spiral strip with a knife; 3, winding the spiral PFA strip on a shaping screw, and placing the screw with the strip in an oven, setting the temperature of 250 DEG C, and baking for 2-3 hours; 4,taking the spiral PFA strip out of the oven, and cooling the strip in purified water to obtain the PFA spring.

Description

technical field [0001] The invention relates to a spring made of a new material. Background technique [0002] A spring is a mechanical part that uses elasticity to work. Generally made of spring steel. It is used to control the movement of parts, alleviate shock or vibration, store energy, measure force, etc. It is widely used in machines and instruments. The types of springs are complex and diverse, divided by shape, mainly coil springs, scroll springs, leaf springs, etc. [0003] Springs are used in various occasions, and metal springs on the market cannot be used in corrosive liquids. If metal springs are to be used in corrosive liquids, the current method is to coat the springs with a layer of corrosion-resistant coating, but the coating is easy to fall off, so the reliability of use is not high, and sometimes the springs have been corroded but cannot be repaired in time. Discover. Contents of the invention [0004] The object of the present invention is to provi...
