Description

Technical Field

[0002] As a component for bearing weight and load, the steel structure base is usually made into a welded part, and its structural form is welded by several steel plates of different sizes; if other components need to be installed on the base, the whole base needs to be machined, and the installation surface is machined in the form of milling or grinding to meet the installation accuracy requirements.

[0003] The existing forms of steel structure bases mainly have the following deficiencies: 1) The structure is formed by splicing and welding plates, which requires a lot of welding work, and both the time and labor costs are relatively high; 2) Continuous welding of large-sized steel plates is prone to deformation, resulting in the need for additional repair of the machined parts after welding; 3) There are too many weld joints, the appearance of the base is not beautiful, and at the same time, the weld joints will also cause stress concentration at some sharp corners of the base structure, affecting the stress uniformity of the base; 4) The overall machining amount is large, the machining difficulty is high, and it is not easy to control the accuracy.
