Bending manufacturers blanking calculation method

Elbow plays a vital role in pipeline engineering, it can effectively change the flow direction and Angle of the pipeline, so as to meet the requirements of engineering design. As an important part of pipeline system, the production of elbow must be accurate, and reasonable blanking calculation is one of the keys to ensure the quality of elbow. Below I will introduce the elbow manufacturers blanking calculation method in detail, hoping to be helpful to readers.

First, the structure and classification of elbow

Elbow is a common accessory in the pipeline system, mainly used to change the flow direction and Angle of the pipeline. According to different use needs, elbow can be divided into different structures and types. Common elbow structures include: 45 degree elbow, 90 degree elbow, 180 degree elbow, etc.; Common elbow types include: elbow, elbow, tee and so on. In the blanking calculation, it is first necessary to determine the required elbow structure and type according to the specific design requirements.

Second, the calculation method of bending

1. Calculate the arc length of the elbow

The arc length of a bend is the length of the curve on one side of the outer surface of the bend. In the calculation of blanking, it is first necessary to determine the arc length of the elbow according to the design requirements, which can usually be calculated by the following formula:
