Description

Technical Field

[0001] The present invention belongs to the technical field of civil air defense door processing, and specifically relates to a high-precision cutting tool for civil air defense door production and a use method thereof. Background Art

[0002] With the improvement of modern industrial level, more and more buildings are being built. In the process of building construction, it is necessary to consider the construction of civil defense infrastructure. Most of the civil defense infrastructure is set up underground. The door used to close the underground civil defense setting is the civil defense door. The civil defense door is the door at the entrance and exit of the people's defense project. The classification of civil defense doors is relatively distinct. There are ordinary single-leaf and double-leaf protective closed doors and closed doors, single-leaf and double-leaf protective closed doors and closed doors with movable thresholds, and other civil defense equipment. Civil defense doors are generally made of steel plates, aluminum alloys, plastic steel and other materials, and have the characteristics of impact resistance, fire prevention, anti-theft, waterproof, and anti-corrosion.

[0003] During the processing of civil air defense doors, cutting is required, and cutting tools are needed for cutting. Most of the existing cutting work only fixes and clamps the two sides of the civil air defense door steel plates relatively. When the civil air defense door steel plates are subjected to a force perpendicular to the fixed direction, they are prone to displacement and misalignment. At this time, the cutting accuracy will decrease during cutting, resulting in defective products. In addition, the civil air defense door steel plates lack longitudinal pressure and fixation, and the fixing effect is poor, making it difficult to ensure good fixing stability. Summary of the invention

[0004] The purpose of the present invention is to provide a high-precision cutting tool for the production of civil defense doors and a method of using the same, so as to solve the problem that most of the existing cutting work proposed in the above background technology is just to fix and clamp the civil defense door steel plates on both sides relatively. When the civil defense door steel plates are subjected to a force perpendicular to the fixing direction, they are prone to displacement and misalignment. At this time, the cutting accuracy will be reduced during cutting, resulting in defective products. In addition, the civil defense door steel plates lack longitudinal pressure and fixation, the fixing effect is poor, and it is difficult to ensure good fixing stability.
