Description

Technical Field

[0001] The invention relates to the technical field of steel plate cutting, and in particular to an automatic steel plate cutting device for producing high-resistance arched protective doors. Background Art

[0002] High-resistance arched protective doors are widely used in places that require high security and protection capabilities, such as military facilities, bank vaults and nuclear power plants. Such protective doors are usually made of high-strength steel plates to ensure that they can withstand explosion impact, penetration attacks and other damage under extreme conditions. The steel plates used to produce such protective doors need to have the following characteristics: high strength and toughness, able to withstand huge external pressure and impact without breaking, corrosion resistance, maintaining long-term stability and durability under various environmental conditions, and processability. Despite the high strength of the material, it still needs to have a certain degree of processability to facilitate cutting and forming.

[0003] Steel plate cutting is one of the key steps in manufacturing high-resistance arched protective doors. The cutting process requires high precision and high efficiency to ensure that the shape and size of the steel plate meet the design requirements. Traditional cutting methods include plasma cutting, laser cutting and water jet cutting. Each method has its advantages and disadvantages. Plasma cutting is suitable for thick plate cutting, but the cutting edge may not be smooth enough. Laser cutting has high precision and is suitable for cutting complex shapes, but its cutting ability for thick plates is limited. Water jet cutting is suitable for cutting various materials, and the cutting surface is smooth, but the cutting speed is relatively slow.

[0004] Many cutting devices still require manual intervention for adjustment and setting when facing steel plates of different specifications and shapes, which reduces production efficiency. Existing automation systems may not be smart enough in optimizing cutting paths, resulting in material waste and increased processing time. Since the steel plates used in the production of high-resistance arched protective doors are thicker and harder, they are more difficult and slower to cut. Summary of the invention
