Use Characteristics Of Shaped Spring Steel Wire

Use characteristics of Shaped Spring Steel Wire
Shaped Spring Steel Wire is a rigorous molding process and heat treatment process from the processing, then the shape of the spring wire which use characteristics? Let's take a brief look at the following:
Shaped Spring Steel Wire is usually under the action of alternating stress long-term work, so have a very high fatigue limit, and good anti-creep and anti-relaxation performance.
In the specific environment used in the spring-shaped wire, the wire will have some special requirements, such as: corrosive media used in the spring-shaped wire, must have good corrosion resistance. Precision instruments used in the spring-shaped wire, should have long-term stability and sensitivity, the temperature coefficient is low, the quality factor to be high, the effect is small, the elastic modulus to be constant. In the high temperature conditions of the spring-shaped steel wire, requiring high temperature can still maintain sufficient flexibility and good creep resistance and so on.
In addition, should also be considered Shaped Spring Steel Wire forming process and heat treatment process. Cold drawn spring steel wire and oil quenched and tempered spring wire steel wire are supplied in the state of steel wire directly wound around the spring wire, Shaped Spring Steel Wire after the elimination of stress treatment directly used.
We all know that the shortened life of the spring-shaped wire is mainly due to wear and tear, then the life of the spring wire depends on what factors?
Although there are many reasons for the broken wire. But the main reason for the broken wire is Shaped Spring Steel Wire fatigue, wear is also caused by one of the reasons, but not the main reason.
Lifting equipment in the course of the use of some damage and abnormal bleeding will cause early broken wire. But the underlying reason is because the shape of spring steel wire toughness is not good, due to stress sensitive.
For most of the cable, especially passenger ropeway, the main reason for the shortening of the life of the spring is due to fatigue. In the freight ropeway, the Austrian-Shaped Spring Steel Wire running for many years, the outer wire was worn very flat, but still no broken wire. The main reason is that it is good material.
There are many reasons for the breakdown of fatigue. From the quality of the Shaped Spring Steel Wire itself, the material and the most affected by the wire drawing process. Bad rope also have an impact. From the use of terms, there is no lubrication, to enhance the shape of the spring wire rope in the reel bite rope, pulley wheel groove is not correct, cable roulette shape discomfort, fixed gripper long time not shift, wheel diameter / Too small and so on are the reasons.
The surface of the spring protection process, mainly: the surface of the rust, finished black (blue), phosphating, paint on the anti-rust oil, electrophoresis paint, electroplating, electrostatic powder coating, especially after the four surface treatment Technology has been widely applied and developed.
Mattress Shaped Spring Steel Wire part of the stainless steel wire and the important use of carbon-Shaped Spring Steel Wire corrosion resistance equivalent to galvanized corrosion resistance, high-frequency infrared carbon and sulfur analyzer if a layer of ZnAl (5%) alloy, then Corrosion resistance can be increased by about 3 times. For the resistance of the performance requirements of stainless steel wire or important use of carbon-Shaped Spring Steel Wire, wire diameter less than 0.4mm can be copper, more than 0.4mm can be used inside the copper, the outside is stainless steel. General wire plated 51μm thick Ni, can improve its conductivity.
Shaped Spring Steel Wire widely used in all aspects of life, mechanical production, aerospace, batteries, electronic equipment. In order to improve the service life of these devices, then it is necessary to improve the life of spring-shaped wire, then how to improve the life of spring-shaped wire?
1, select the appropriate Shaped Spring Steel Wire
Shaped Spring Steel Wire many types of different types of spring-shaped steel wire used in different occasions, if the wrong shape spring steel wire quality, then the service life will be greatly reduced.
2, Shaped Spring Steel Wire of the maximum capacity
Shaped Spring Steel Wire has a maximum bearing capacity, that is, if the load exceeds the maximum load will damage the spring, so that the spring can not be restored to normal size, resulting in damage to the spring.
