How to cut the elbow of the 30 degree 300 mm round pipe with equal diameter

At present, the most convenient thing is to use software to automate the blanking drawing.

You can try this.

Rigid CAD is top-notch.

The sheet metal method applicable to the equal diameter round elbow is the parallel line method.

1. Draw a top view according to the radius of curvature of the elbow and the diameter of the pipe;

2. Draw the end section according to the number of sections. In the case of three sections, the two end sections are, and the middle section is 45°, that is, the entire 90° is divided into four equal parts, and then tangent lines are made from the two ports and the 45° intersection arc, and the elbow is simplified into a combination of cylindrical sections;

3. Based on the obtained end segment, the parallel line method is used, and the diagram of the middle section is the synthesis of the end segment diagram after flipping 180° around the horizontal line.

Cylindrical section parallel line method steps:

1. Draw a semicircular arc connecting the two ends of the horizontal line with the midpoint of the horizontal line of the truncation platform as the center of the circle and the radius of the round pipe as the radius;

2. divide the semicircular arc into six equal parts to obtain five intersection points on the arc, and obtain five parallel lines of the interception platform from the vertical line intersection of the horizontal line of these five intersection points, and the other two contour lines of the interception platform are the solid length lines of the interception platform;

3. Make an extension line of the horizontal line, take a certain point as the starting point to arrange the seven parallel lines in order at one-sixth semicircular arc length intervals, and then connect the vertices of the seven parallel lines with smooth arcs, that is, half of the end section diagram is obtained, and the diagram is flipped 180° to the left or right to obtain the complete diagram of the end segment.

1. The curvature is 90 degrees, and the diameter of the hole imitation sun is 300mm, which is cut like this: the length of a straight line is (d-t), where d is the outer diameter of the round pipe, and t is the thickness of the plate. 2. The line section is divided into 16 equal parts, and the two sections of the equal diameter right-angle elbow lofting calculation formula is buried

yn=r cos, when 0° n 90°, yn=1 2(d-2t)cos; When 90°

The length of the 90 degree elbow = the bending radius (nominal diameter * multiple). The formula for calculating the size of the elbow is the length of the elbow = the bending radius (nominal diameter * multiple). 2. Poke height = center height + radius of the elbow, such as the poke of the elbow with a diameter of 219 = 305 + 219 2 = 305 +.

3. The length of the outer arc = (center height + radius) * degree, that is, (poke height) * degree, from which it can be deduced that the outer arc length of the 90-degree elbow = poke height *. 4. Inner arc length = (center height - radius) * degree. 5. The cutting length of the elbow = the height of the center of the elbow * the outer diameter of the elbow The diameter of the pipe + (the wall thickness of the pipe * 3) + the processing allowance, such as the pipe blanking of 180 * 8 and the elbow of 273 can be calculated with the above formula, the blanking length = 381 * machining allowance.

Summary. Pro, 90 degrees three-section elbow blanking, first according to the size of the drawing target lofting, divided into twelve equal parts, according to the geometric size of the line after the line, and then cut off the excess part, the template can be cut successfully, the size of the sample must be the diameter of the elbow perimeter size and add a margin.

1. You need to measure the size of the specific elbow you need, and then cut it and draw a vertical line on the length you need.

2. After that, use a marker pen to draw a horizontal 90-degree inner angle from the side, and then do a double 45-degree oblique cutting process, and at the same time, you need to use a cutting machine to cut out a relatively complete sample, so that the 90-degree elbow of the pipeline can be made.

320 tube, I want to do three elbows, can you tell me the size of each section.

Pro, 320 tubes, do three elbows, the size of each section is about 86.

What is the size of the narrow side and what is the size of the wide side.

Dear, the size of the narrow side is 76, and the wide side is 82

Summary. 1. When designing, first of all, it is necessary to cut two pipes of the same diameter to 45 degrees, and according to professional equipment, the cutting angle can be guaranteed to be very accurate. Then the interface butt is welded together, and the 45-degree elbow is used as a pipe fitting or connector, which is mainly used in the branch pipeline of the main pipeline.

2. Connect two pipes with the same diameter to make the pipeline turn in a 45-degree direction. Generally speaking, the connection should be made by direct welding, or by hot melt connection, or by socket connection or flange ring. If it is divided according to the production process, there is a welding elbow or a casting elbow.

According to the material, it is generally a 45-degree elbow of the carbon steel type.

What are the methods of pipeline connection 1. Whether it is a living pipeline or a construction pipeline, the correct connection method needs to be taken. For example, it can be connected by threaded connection, that is, through a threaded pipe fitting, which is generally used for pipes with relatively small pipe diameters, and most of them are surface-mounted pipes.

2. There is also a flange connection, which is connected together by a pipe with a relatively large diameter, which is generally used in the check valve or water meter, so as to disassemble and repair it in the later stage, and the galvanized pipe can also be used in this way. 3. The welding method is the most common and suitable for non-galvanized steel pipes. If it is a pipe with a relatively large diameter, it is especially used in some high-rise buildings.

4. There is also a method of connecting through clamps, such as fire pipes or air conditioning cold water pipes and rainwater drainage pipes, which can choose this groove connector. The operation is relatively simple and the stability is good.

Can you draw a diagram and how to stake out?

I'm not a professional at this, so I can't provide it to you, please understand.

Draw a line on the round tube, draw a 45-degree angle, draw a cut down, and connect the two 45-degree elbows.

The method of blanking the 90-degree elbow of the round pipe usually includes the following steps:

1.Determine the length of the material: First, determine the required length of the round pipe according to the size and specification of the elbow to be made. Taking into account the radius of curvature and bending angle of the elbow, make sure that the bending length of the round pipe is sufficient to make the elbow and leave an appropriate margin.

2.Make a template: According to the design requirements of the elbow, make a template to assist in blanking and bending. The formwork should have the required bending angle and bending radius.

3.Adjustment of cutting angle: fix the round pipe on the workbench, and use a saw or cutter tool to cut the material according to the desired elbow shape and size according to the guide line of the template. According to the instructions of the template, adjust the angle and depth of the sawing to ensure precise cutting.

4.Bending: The blanked round pipe is fed into a pipe bender or other applicable bending equipment to bend according to the desired angle of 90 degrees and bending radius. Ensure that the tubing remains stable during bending and that appropriate precautions are taken to prevent excessive bending or damage.

Please note that cutting and making round pipe elbows may require specialized tools and skills. For specific projects and requirements, it is recommended to consult professional pipe fabricators or engineers for more accurate guidance and operation advice. At the same time, ensure that safe operating procedures are followed during operation and that appropriate personal protective equipment is used.

Diameter 325 steel pipe. 90 degree elbow 4 section production method.

Hello dear!...Diameter 325 steel pipe. 90 degree elbow 4 section production method.

If you want to make a round pipe into a 90-degree right angle, then you must first prepare a long round tube, and then use a cutting machine to cut the round pipe in half, and then use a cutting machine to cut one end of one of the round pipes into a 45-degree bevel, and the other round pipe should also be cut into a 45-degree bevel shape, the next step is to align the two 45-degree beveled pipes, so that the round pipe forms a 90-degree right angle. After fixing, you can also brush some special pipe glue at these two bevels, and the 90-degree pipe elbow is successfully made. Hello dear!...

Summary. Sheet metal patterns are generally lofted by the intersecting line method, and there is no calculation formula.

Drawing software is more convenient to draw.

There is no CAD software, lofting mobile phone software, but there is.

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.

The bending radius must be known for elbow cutting, and the diameter of the steel pipe is 325. 90 degree elbow 4 section production method.
