Metal cutting machine

Abstract

The invention relates to a metal cutting machine. The metal cutting machine comprises a base, a support arm, a cutting head, a clamping device and a spark catcher component, wherein the support arm is fixedly mounted on the base, the cutting head is pivotally connected with the support arm, the clamping device is mounted on the base and comprises a first clamping part close to the support arm and a second clamping part distant from the support arm, and the spark catcher component comprises a first side wall. The first side wall extends backwards from the first clamping part along the direction basically parallel to the plane where a blade is located, the second side wall is opposite to the first side wall, and a gap is formed between the first and second side walls. During cutting, at least a part of blade enters the gap, and the third side wall is connected with the rear end of at least one of the first side wall and the second side wall, so that the rear of the spark catcher component is closed, and the front and the upper of the spark catcher component are at least partially opened. By the spark catcher component of the metal cutting machine, sparks generated during cutting are effectively controlled and splashing of the sparks is avoided.

Description

technical field [0001] The present invention relates to metal cutting machines, and more particularly to spark shield assemblies for metal cutting machines. Background technique [0002] The metal cutting machine will generate a lot of sparks when cutting metal, and the sparks will fly in all directions. The high-temperature sparks will easily burn the human skin or burn the surrounding objects. [0003] In order to prevent the sparks from flying around, some operators place the metal cutting machine in the box for cutting, but the sparks splashing on the inner wall of the box will reflect, and the reflected sparks are still not effectively controlled. [0004] In the prior art, some metal cutting machines are equipped with a straight or small arc-shaped spark cover to prevent the sparks from splashing to the rear of the cutting machine, but the sparks splashing backward will also be reflected after hitting the spark cover. Part of the reflected sparks will fly to the opera...

[0003] In order to prevent the sparks from flying around, some operators place the metal cutting machine in the box for cutting, but the sparks splashing on the inner wall of the box will reflect, and the reflected sparks are still not effectively controlled

[0004] In the prior art, some metal cutting machines are equipped with a straight or small arc-shaped spark cover to prevent the sparks from splashing to the rear of the cutting machine, but the sparks splashing backward will also be reflected after hitting the spark cover. Part of the reflected sparks will fly to the operator, and the other part of the reflected sparks will diverge in other directions, resulting in a large area of ​​sparks splashing in the cutting workpiece area, and the splashing sparks have a short-term high temperature, which is easy to hurt the operator
