Calculation method of white iron sheet blanking of pipe elbow

Sheet metal patterns are generally lofted by the intersecting line method, and there is no calculation formula. Drawing software is more convenient to draw.

The multi-knob elbow is called "shrimp waist".

Manual Loft Steps: (Take one section as an example, the rest of the methods are the same).

1) Draw the side projection of the elbow according to the actual size. Seam lines included.

2) Divide each closed wireframe graphic into an independent graphic by line. (You can crop it or repaint it separately.)

3) Take a pattern, draw it on another sheet of paper, draw two horizontal lines parallel to the top and bottom along the height of the pattern, and perpendicular to the centerline, length.

It is exactly the circumference of the diameter of the pattern. (closed rectangle).

4) Divide the pattern vertically and mark it, and then draw these bisecting lines vertically into the rectangle just drawn, noting that the points on the map must correspond to the points on the projection pattern.

5) Divide the upward diagonal line of the drawing in equal directions in the horizontal direction. and pull parallel to the pattern, and correspond to the corresponding point. The intersection points obtained on the sample are smoothly connected, which is the curve. The denser the aliquot, the more accurate the curve.

6) The amount of the bite is released, and the thickness of the plate is treated.

Will you stake it now, if not, your formula is hard for you to understand.

Because it is related to the common name in this regard.

I'm afraid no one else will have such a simple formula.

Such as: straight length, bending multiple, number of middle sections, outer diameter, etc., and.

1 line = 2 lines =

3 lines = 4 lines =

5 lines = 6 lines = 7 lines =

White iron elbow blanking calculation drawing.

It's all something that can be easily done with this software.

Thermal insulation white iron elbow blanking, calculation formula, manual blanking, ask the great god to teach.

Hello! Introduction to the simple and stupid formula of iron elbow cutting, this formula is mainly for the development and research of elbow cutting in the construction of pipeline insulation cladding iron sheet, (pipe diameter + radius + thickness of insulation layer) 2 copies = width of the large surface of the elbow. After calculating this data, it is necessary to calculate 2=half of the large surface of the elbow, and this data is to be used on the auxiliary circle.

Plane of pipe insulation elbow**: The above is a simple calculation formula for the large surface of the elbow, and the following is a description of the calculation formula for the small surface; Pipe diameter number = width of the small surface of the elbow, after calculating this data or 2, to get half of the width of each piece of elbow piece, this data should be used in the auxiliary circle, the following is the ** of the auxiliary circle, I hope you can understand, through the above two formulas to match the two data respectively on the way to the above auxiliary circle (7 magnified surface data); (1) put small area data); Then connect the two data, so that the projection of the elbow is made, so that the 1234567 data is obtained. Seeing this, is it a lot of awakening.

The two formulas I introduced above are the simple and stupid formulas I used before, dead routines, the advantage is that the calculation is fast, and the disadvantage is that the elbow of the opposite sex is not good, and the elbow that is too big or too small is not good-looking.
