Calculation method of drag chain bending radius

    Drag chain is often used to protect wires and cables in motion. It is a type of machine tool accessory. As a highly flexible, bending-resistant connection and control device, the number of continuous bending and frequent movements can exceed five hundred times under medium, high, and conventional mechanical stress. More than 10,000 times, the bending radius design of the drag chain is relatively strict, because whether the bending radius meets the standard has the most direct impact on the stability and life of the drag chain. When ordering products, buyers also need to check the length, length, and length of the drag chain. Specific parameters such as width, inner height, inner width, and bending radius must be professionally understood. Wrong selection will affect the operation of the entire equipment. So how to calculate the bending radius of the drag chain?

Calculation method of drag chain bending radius

1. How to measure the bending radius of the drag chain?
Bend and fold the drag chain, find the highest and lowest vertical points, and measure the distance between the two nodes. The bending radius of the drag chain is equal to half of the measured diameter.

2. How to calculate the bending radius of the drag chain?
At the beginning of the calculation, we need to know the meaning of the following characters: L represents the total length of the drag chain, L1 represents the drag chain stroke, and R represents the bending radius of the drag chain
  The calculation formula of conventional drag chain length is as follows: L=4XR (bending radius) + L1/2, rounded to an integer.
L=πR+0.5R+L1/2, (this calculation method is suitable for installation at lower positions)
The total bending height of the drag chain = bending radius * 2 + drag chain plate height
The calculation formula for the bending radius of the steel drag chain: Drag chain bending radius = (total drag chain height after bending - drag chain thickness)/2. The larger the bending radius of the drag chain, the higher the total bending height will be.

3. Things to note when choosing bending radius
The correct selection of the bending radius also needs to be based on the actual height and space restrictions. The bending radius should be smaller than the empty space height of the equipment. In addition, the bending radius should reach 10 times the maximum diameter of the cable. The selection range is 75-650mm. For small strokes, choose a drag chain with a smaller bending radius.
