Industrial Carbon Steel With Nickel Plating Double Torsion Springs
Torsion springs belong to the category of spiral springs. Torsional springs can store and release angular energy or statically hold a device by rotating a moment arm about the central axis of the spring body. The end of the torsion spring is fixed to the other components, and as the other components rotate around the center of the spring, the spring pulls them back to their initial position, generating torque or rotational force.
Such springs are usually close-fitting, but the springs are spaced to reduce friction. They exert resistance to rotation or rotational forces. According to the application requirements, the design of torsion spring rotation (clockwise or counterclockwise), so as to determine the spring rotation.
When the spring twists, the material is in a tensile or shear state as mentioned in the torsion calculation, so the torsion Angle limit is ultimately caused by the failure of the material, which cannot be restored to its original state when plastic deformation occurs. Of course, the Von Mises stress calculated by the fourth strength theory is the maximum strength that the material can withstand. Combined with the length of the spring, the maximum allowable torsion Angle can be calculated.
Torsion spring production process:
spring wire → spring winding → low temperature stress relief annealing → high temperature degreasing → washing → dilute hydrochloric acid washing → washing → electric galvanizing (80 min) → washing → blanking → dehydrogenation treatment (200 ℃, 4 h) → feeding → washing → color passivation → washing → drying → blanking → inspection

1. What is a torsion type spring?
A: A torsion spring is a spring that works by twisting its end along its axis; that is, a flexible elastic object that stores mechanical energy when it is twisted. When it is twisted, it exerts a torque in the opposite direction, proportional to the amount (angle) it is twisted.
2. Why do torsion springs break?
A: When the garage door is lowered, the springs gain tension. When raising the garage door, tension is released and the spring assists with the lifting. It's important to note, your garage door springs have the most tension when the garage door is closed. As a result, most garage door springs break when the door is down.
3. How much wind Should a garage door spring have?
A: A rule of thumb with springs is that four quarter turns equals a full revolution and the spring needs to be tightened a full revolution for every foot of door height (e.g. 7-1/2 foot door = 7 revolutions +2 (30 quarter turns).
4. How do you strengthen a spring?
A: If you make the wire diameter larger, you will make the spring stronger and if you make it smaller, you will make it weaker. This is because, by making the wire diameter larger, you are also making the spring's coils tighter which reduces the spring index.
5. Where are torsion springs used?
A: A torsion spring is commonly used in clothes pins, clipboards, swing-down tailgates and garage doors. Other application types include hinges, counterbalances and lever returns. Sizes range from miniature, used in electronic devices, to large torsion springs used in chair control units.
