Degrees of division after the cylinder is rolled into a circle
Thread Content
Let’s talk about how, in your factory, the cylinders are aligned to 4 positions of 0°, 90°, 180°, and 360° after being rolled into shape. Once they’re aligned in these positions, how is it checked? Does anyone have an accurate and simple method for this?
It’s probably the same in all cases: measure the perimeter and divide it by the angle :)
This is the *common term used by container manufacturers; generally it refers to the four centers, namely the upper center, lower center, left center, and right center, which can be determined based on the outer circumference! !
Check according to the layout diagram, based on the angle at which the weld is located
I mean, how do we determine that the 0 degrees on the left and right are on the same horizontal line?
After measuring the circumference of the cylinder, divide it into four equal parts, and determine each direction according to the layout diagram
1. Determine the degree and make markings before rolling the sheet. 2. After rolling, divide it into sections using the center of the weld as a reference
Divide the outer circle of the disk into four equal parts – if anyone has a better method, please share it
Who has a good and accurate method to tell me? Once it’s divided, how can I check the levelness of the 0-degree lines on the left and right?
