Groove cutting device for shipbuilding steel plate

Abstract

The invention relates to the technical field of shipbuilding steel plate machining, and discloses a groove cutting device for a shipbuilding steel plate. The groove cutting device comprises a machine table, wherein supporting plates are fixedly connected to the left side and the right side of the bottom of the machine table in a vertically downward mode, a bearing plate is fixedly connected between the two supporting plates, jacking cylinders are fixedly mounted on the left side and the right side of the upper portion of the bearing plate in a vertically upward mode, the upper ends of piston rods of the jacking cylinders are fixedly connected with the same bearing platform, and a plurality of jacking rods distributed at equal intervals are fixedly connected to the upper portion of the bearing platform in a vertically upward mode. According to the device, the two jacking cylinders operate to drive the bearing platform to increase the height so as to guarantee that multiple guide rollers on the bearing platform stretch out of a rectangular through opening of the machine table, the steel plate can be flexibly guided and moved under the action of the guide rollers until the left side of the steel plate is attached to the right side face of a limiting baffle on the left side of the machine table, and the alignment locating effect of the steel plate is guaranteed.

Description

technical field [0001] The invention relates to the technical field of shipbuilding steel plate processing, in particular to a bevel cutting device for shipbuilding steel plate. Background technique [0002] At present, due to the harsh working environment of the ship, the hull shell is subject to chemical corrosion, electrochemical corrosion, marine organisms, and microbial corrosion of seawater; the hull is subjected to large wind and wave impacts and alternating loads; the shape of the ship makes the processing method complex and other factors, Therefore, there are strict requirements on steel for hull structure. First of all, good toughness is the most critical requirement. In addition, high strength, good corrosion resistance, welding performance, processing and forming performance and surface quality are required. [0003] The retrieved publication number CN 210549083 U discloses a bevel cutting device for shipbuilding steel plates, including a cutting platform, the c...

AI Technical Summary

Problems solved by technology

[0005] First, there is no limit measure when the steel plate is cut in this technical solution, which will easily cause the situation that the steel plate will always be displaced during the cutting process;

[0006] Second, the cutting machine in this technical solution has no limit measures, and it is impossible to quickly determine whether the cutting edge of the steel plate is in alignment with the cutting mechanism, and the practicability is low
