Advantages of bolt ball joints and five points for attention in bolt ball machining of grid structure

Advantages of bolt ball joint:
Bolt ball is composed of steel ball, high-strength bolt, fastening bolt, sleeve, cone head or sealing plate and other parts. It has multiple holes with internal thread on one ball, which is used to connect multiple members at one point. It is mainly used in grid structure and plays the role of connecting members. Bolt ball is widely used in the field of tubeless downhole production equipment, tubing drift diameter gauge, etc. it has the characteristics of small node, light weight, wide application range and convenient use.
       Bolt ball processing has many advantages, such as fast construction speed, good integrity, stable structure, large space stiffness, and effective use of space. It is favored by all major construction industries. When processing bolt ball of grid structure, workers should pay attention to the processing materials and production requirements. Bolt ball required for different parts will exist no matter the size of the ball or the size of the hole Certain differences, so in the processing must pay attention to, in addition to pay attention to the process of processing burrs and cracks.
In the process of bolt ball machining, the precautions are inevitable. The five precautions of bolt ball machining can improve the safety of bolt ball grid structure.
I. The quality and specification of materials required for bolt ball processing shall meet the quality requirements specified in standards and design documents.
II. Technicians shall review the construction drawings, refine the node structure, and design the processing details of the project according to the drawings.
III. before cutting the grid steel, the cutting area shall be carefully cleaned to remove rust, oil, splashes on the edge and other impurities.
IV. when setting out and measuring bolt ball processing, reserve welding shrinkage and equal processing allowance for cutting, edge planing and milling according to process requirements.
V. there shall be no cracks and missing edges larger than 1.0mm on the processing fracture of bolt ball, and the burrs around the weld shall be removed.
