Description

Technical Field

[0001] The invention belongs to the technical field of laser cutting, and in particular relates to a device for cutting high-speed railway door columns. Background Art

[0002] Laser cutting uses a high-energy-density laser beam to heat the workpiece, causing the temperature to rise rapidly and reach the boiling point of the material in a very short time. The material begins to vaporize and form steam. The steam is ejected at a very high speed, and as the steam is ejected, an incision is formed on the material. High-speed rail door columns are an indispensable part of high-speed rail and railway infrastructure construction. They mainly play the role of support, fixation and protection. High-speed rail door columns are usually made of high-strength materials, such as steel, to ensure that they have sufficient strength and stability. This requires the use of laser cutting when processing high-speed rail door columns.

[0003] Since the high-speed rail door column is a three-dimensional structure, it is sometimes necessary to cut each surface of the column during the cutting process. Since the existing laser cutting equipment cannot freely adjust the cutting direction, the column needs to be rotated to change the direction to cooperate with the laser cutting equipment. This process requires frequent removal and reinstallation of the column from the positioning tooling. The steps are cumbersome and the processing efficiency is low. Moreover, some high-speed rail door columns with uneven shapes and some high-speed rail door columns with cutting inclination requirements will be difficult to cut.

[0004] Therefore, a device for cutting a high-speed railway door column is proposed. Summary of the Invention
