Door torsion spring
The more commonly used door torsion springs are torsion springs and compression springs, which are installed on the mandrel of the door hinge, and when the door is pushed open, it is necessary to apply pressure to the hinge plate when the door is automatically closed after being released.
The door torsion spring, also known as the door hinge spring, is a relatively safe and useful device in some cases. This kind of spring is more common in the market, of course, this kind of spring can also be customized to meet your different needs.
The installation of the door torsion spring can enable the door to open and close normally. The effect of the door automatically closing is time through the torsion spring, because one leg is installed on the fixed plate and the other leg is installed on the plate on the door. When the door is opened, the torque is applied to the door, and once the door is released, it will exert pressure on the door to return to the original free position.
Advantages of door torsion spring:
Design principle of door torsion spring:
When we were designing the spring for the door,we need to calculate the weight of the door and the Angle at which the door is going to swing or move. We also need to calculate how many hinges we need to go out, so we know how many springs we need.
Because the springs work in parallel, the force you need divided by the number of springs you need, so that all the springs working together will give you the corresponding force value.At the same time, when it is installed on the hinge, we also need to consider the diameter of the shaft or shaft, so that the card will not be tight during installation, thus affecting the use of it.
Knowing the space in which the door torsion spring is installed also helps to ensure that it meets the desired function, which means we need to measure the space length of the shaft or mandrel of the door hinge, the position of the spring, and the outside space you can use.
These measurements place limits on the length and outside diameter of the spring. The body length is based on the wire diameter of the spring and the total coil, and the outside diameter is based on the inside diameter and wire diameter.
The following is the material type to choose, the most affordable material is the music line.This type of material is recommended for indoor use, as it cannot be used in hot, humid or corrosive environments.The next option is for door torsion springs to be used outdoors, and 302 stainless steel is the more common and affordable type of stainless steel wire, so this type of material is also a good choice. If the environment where your door is located is more complex, you can contact us to customize the door torsion spring according to your use environment.
The door torsion spring can be adjusted according to the strength of the spring and the opening Angle, so that the door can be opened and closed quickly and smoothly, which has a protective effect on the door body and door frame, avoid noise and damage caused by violent closing, and meet the needs of different occasions.
High quality door torsion springs are well designed and well manufactured to ensure stable performance during long-term use and reduce the possibility of failure.
