Method for producing container bottom cross beam

Abstract

The invention relates to a production method for the container bottom beam, which comprises a striping procedure and a molding procedure; wherein, the striping procedure comprises: A1: unreeling the wide roll material and extract the sheet metal continuously; A2: gripping blasting the sheet metal continuously; A3: spraying painting or roll painting and drying continuously; A4: strip coiling the dried sheet metal to get the narrow roll material. The molding procedure comprises: B1: unreeling the roll material and extract the sheet metal continuously; B2: sending the roll material to the mill continuously, cold roll to the continuous profile material of specified section with a plurality of rollers of the mill; B3: cutting off the continuous profile material to specified length. The invention has the advantages that: in the processing of molding, the working procedures, such as unreel, molding and shear are completed continuously, without stowing and swinging for the workpiece respectively, which greatly improves the productivity; furthermore, spray painting or roll painting is processed to the wide roll material, avoiding the paint waste and environmental pollution caused by processing more difficult spray painting working procedure to the striped narrow roll material and the molded profile material, making the environment more friendly.

Description

technical field [0001] The invention relates to a production process of a container, more specifically, to a forming method and a production method of a container bottom beam. Background technique [0002] With the development of economy and trade, containers, as an important means of transportation, are used more and more widely, and the demand is very large. Most of the current containers adopt a frame structure, and a plurality of bottom beams are arranged at the bottom of the container to support the bottom plate of the container. Most of the existing container bottom beams adopt decentralized processing methods, including cross-cutting, sanding, cutting, bending and other processes. [0003] Cross-cutting: open the coil material, such as a steel coil; then, cut it into a certain length of sheet material, and unload and stack it; then use the lifting machine to lift the sheet material to the pre-sanding processing line, waiting for sanding . [0004] Sanding: The cros...
