Underwater cutting jig frame

Abstract

The invention provides an underwater cutting jig frame. The underwater cutting jig frame comprises a box body, wherein a platform is mounted in the middle of the inner side of the box body; a material frame is arranged on the upper side of the platform; a group of air pipelines are arranged in the box body; an air chamber is buckled on the upper side of the box body; a bracket is arranged above the air chamber; a material frame is arranged above the bracket. According to the underwater cutting jig frame, compressed air is injected into the jig frame, so that water is raised and exceeds a to-be-cut sheet material, the to-be-cut sheet material is cut by a plasma cutting machine, and the water is saved; each part can be detached according to requirements, so that the underwater cutting jig frame is greatly convenient to clean and maintain.

Description

technical field [0001] The invention relates to a cutting tire frame, in particular to an underwater cutting tire frame used for a plasma cutting machine. It belongs to the field of offshore oil engineering. Background technique [0002] At present, flame cutting is mostly used for cutting marine steel structure plates. However, the flame cutting method not only has a slow cutting speed, but also consumes a large amount of cut plates; moreover, a large amount of dust is generated during flame cutting, which has a great impact on the environment. Simultaneously, because the tire frame for flame cutting is generally an integral type, that is, it cannot be disassembled, which brings great inconvenience to the field cutting of plates. In order to overcome the above disadvantages, the plasma cutting machine is used to cut the plate. However, since the plasma cutting machine uses high temperature and rapid melting to cut metal, when the flame cutting tire frame is used for cutti...

AI Technical Summary

Problems solved by technology

However, the flame cutting method not only has a slow cutting speed, but also consumes a large amount of cut plates; moreover, a large amount of dust will be generated during flame cutting, which has a greater impact on the environment.

At the same time, because the flame cutting tire frame is generally integral, that is, it cannot be disassembled, which brings great inconvenience to the site cutting boards

In order to overcome the above disadvantages, the plasma cutting machine is used to cut the plate. However, since the plasma cutting machine uses high temperature and rapid melting to cut metal, when the flame cutting tire frame is used for cutting, it is easy to deform the cut rod. It is also very easy to damage the cutting tire frame

Therefore, in order to facilitate the operation, the operator places the plate in a box-type tire frame and injects water into the box during the process of cutting the plate; at the same time, the plate is cut by setting up a scaffold above the box; due to water injection Cutting needs to be done without the plate. Therefore, the water consumption of the box-type tire frame is large during the process of cutting the plate; and due to the large span between the scaffold plates, it is easy to step on the air and collapse accidents; it is also easy to cause small rods After cutting, it falls from the gap between the boards and cannot be taken out; at the same time, it is not easy to clean and maintain
