Vertical anti-dewatering cutting machine of asbestos cement plate

Abstract

The invention discloses a vertical anti-dewatering cutting machine of an asbestos cement plate. The vertical anti-dewatering cutting machine structurally comprises a cement plate limiting frame, a cement plate transmission machine, two supporting feet and an asbestos cement plate cutting machine; and the cement plate limiting frame is fixedly mounted at the head end of the cement plate transmission machine, the two supporting feet are fixedly welded to the front end and the rear end of the cement plate transmission machine, the asbestos cement plate cutting machine is fixedly mounted at the tail end of the cement plate transmission machine, and the asbestos cement plate cutting machine and the cement plate limiting frame are parallel to each other. Heat energy generated during cutting of ahigh-speed cutting tool is absorbed through a heat transfer compression mechanism, thus the temperature of the high-speed cutting tool is decreased, the heat energy can further be utilized to work ona spiral cooling mechanism, structural water in asbestos fibers is absorbed to be injected onto a cutting opening, thus the asbestos fibers are protected, and cracks in the surface of the cement plate are reduced; and meanwhile, the heat energy generated during cutting is transferred to a cutting opening anti-fracture mechanism, thus the cutting opening anti-fracture mechanism tightens the cutting opening of the asbestos cement plate, impact force generated by the cutting opening of the asbestos cement plate and the high-speed cutting tool is lowered, and the situation of fracture of the cutting opening of the asbestos cement plate is reduced.

Description

technical field [0001] The invention relates to the field of cement board cutting, in particular to an anti-dehydration cutting machine. Background technique [0002] Asbestos is a kind of silica hydrochloric acid mineral fiber widely used in building material fireproof boards. Asbestos cement board is one of the building material fireproof boards. It is necessary to use a vertical cutting machine to cut asbestos cement board for ease of use. However, the current vertical There are the following disadvantages to the cutting machine: [0003] 1. The structural water content of asbestos fibers is 10%-15%. When cutting, the temperature will rise sharply. At this time, the structural water of asbestos fibers will be precipitated, and the fiber structure will be damaged, causing the cement board to become brittle. Easily cracked and unusable. [0004] 2. And the impact strength of the asbestos cement board is low. When cutting, because the high-speed cutting tool runs at a high...

AI Technical Summary

Problems solved by technology

[0003] 1. The structural water content of asbestos fibers is 10%-15%. When cutting, the temperature will rise sharply. At this time, the structural water of asbestos fibers will be precipitated, and the fiber structure will be damaged, causing the cement board to become brittle. Cracks easily and cannot be used

[0004] 2. And the impact strength of the asbestos cement board is low. When cutting, because the high-speed cutting tool runs at high speed, the momentary impact force of the asbestos cement board and the high-speed cutting tool is very large, causing the cutting edge of the asbestos cement board to break.
