Container, wide steel plate and continuous splicing welding device

Abstract

The invention discloses a container, a wide steel plate and a continuous splicing welding device. The continuous splicing welding device comprises a first uncoiling and flattening unit which is used for flattening a first narrow steel plate coil, a first cutting unit which is used for performing laser cutting processing on flattened first narrow steel plate lateral edges requiring splicing welding, a second uncoiling and flattening unit which is used for flattening a second narrow steel plate, a second cutting unit which is used for performing laser cutting processing on flattened second narrow steel plate lateral edges requiring splicing welding, a guiding butt joint unit which is used for enabling lateral end surfaces along the length direction of orderly cut first narrow steel plate and second narrow steel plate to be closely adhered and a welding unit which is used for performing laser welding on a connection position of the closely adhered first narrow steel plate and second narrow steel plate to obtain a narrow steel plate which the middle provided with a smooth welding seam. The continuous splicing welding device has the advantages of efficiently splicing the two narrow steel plates into the wide steel plate continuously and accordingly improving the integral container manufacturing efficiency greatly.

Description

technical field [0001] The invention relates to the processing of the plate of the container, especially related to the processing of the top plate, side plate or front end plate of the container. Background technique [0002] Limited by the width of the existing steel plate, for example: the maximum economical processing width cannot exceed 2 meters, that is to say, the width of the steel plate cannot meet the requirements for the width of the top plate, side plate or front end plate of the container. The top panel, side panel or front panel of the container is usually realized by the complicated cutting and splicing process of narrow steel plates. For example, the manufacturing process of the existing container roof generally includes: making a single flat panel unit from a steel coil; making a single roof unit finished product from a single flat panel unit; and making a container roof panel from more than five single roof unit finished products. Among them, the process o...

Problems solved by technology

[0004] 1. Because it is divided into several small parts for manufacturing, there are many processes, the manufacturing cycle is lengthened, and the efficiency is low;

[0005] 2. There are errors in the manufacturing process of each small part. When the overall combination is carried out, the cumulative error is relatively large, which is unfavorable to the final assembly;

[0006] 3. After assembling the small semi-finished products, it is necessary to weld the joint parts. Since there are many parts to be welded and the length of the weld seam is long, the welding deformation is large and there are many welding defects;

[0008] 5. Since it is divided into several small parts for processing, there are many processes, many workbenches, a large floor area, and a large number of workers at the same time

The shortcomings of this scheme are as follows: the weld seam protrudes from the surface of the steel plate, making it difficult to carry out subsequent corrugated press forming processes, the thermal stress of the weld seam has a large area of ​​influence, and cracks are prone to appear in the follow-up processing, and it is impossible to find the two The method of continuously welding narrow steel plates into wide steel plates is so inefficient that this scheme has not been practically applied
