Embodiment 1

[0071] The manufacturing method of large hopper of the present invention comprises the following steps:

[0072] a, blanking, including the following steps:

[0073] (1) A36 steel plate blanking

[0074] 1) Lofting should be based on process requirements, and consider welding shrinkage allowance, cutting, planing and milling allowance; the number of materials should be marked on the steel parts with component number, part number, quantity, groove type, material, and team Information, the thickness of the stone pencil line used for stakeout and numbering shall not exceed 0.5mm, and the thickness of the elastic line of the chalk line shall not exceed 1mm;

[0075] 2) Straight strips must be cut by a multi-head straight strip machine, and special-shaped parts should be loaded and unloaded by a CNC cutting machine, and shaped steel should be unloaded by a sawing machine, profile cutting machine, and vertical cutting machine;

[0076] 3) For mechanically sheared parts, the thickn...

Abstract

The invention discloses a large hopper manufacturing method, wherein the upper part of a hopper is equipped with a cylindrical barrel body, and the lower part of the hopper is equipped with a taperedhopper which is round and square. The large hopper manufacturing method is characterized by comprising the following steps of: a, unloading; b, drilling; c, bending and forming a wall plate of the hopper; d, assembling; e, welding; f, pre-assembling; and g, coating. The large hopper manufacturing method has the advantages that hopper manufacturing steps are reasonable in design, operability is strong, manufacturing is convenient, construction is simple and convenient, a construction period is short, project quality is guaranteed to be excellent, hopper manufacturing engineering cost is reduced, and the good result of saving 0.1035 million RMB is achieved.

Description

technical field [0001] The invention relates to a method for manufacturing a process steel structure for storing materials, in particular to a method for manufacturing a large hopper. Background technique [0002] The large hopper is a special hopper for storing cement materials. Its upper part is a cylindrical cylinder, and the lower part is a conical hopper with a round sky. The inner diameter of the upper cylindrical cylinder is 10.6m, and the height is 6.8m. The cylinder body and hopper wallboard are made of American A36 material wallboard, and the inside is covered with NM500 material thickness 20mm lining board. The lining board and the wall board are connected by on-site welding. The total height of the hopper is 12.733m and the total weight is 110 tons. The large hopper was designed by ThyssenKrupp in Germany, manufactured in China, and transported by container to the Peruvian factory for on-site installation. Large-scale hoppers are limited by the size of the trans...
