Description

Technical Field

[0001] This utility model belongs to the field of metal parts processing technology, and in particular relates to a protective device for metal cutting. Background Technology

[0002] One of the most common processing operations in the metal parts manufacturing process is cutting. When cutting metal parts using cutting equipment, a lot of metal fumes and sparks are generated. The sparks have a high temperature, and the fumes also contain a lot of harmful substances. Therefore, protective devices are required when cutting metal parts to deal with the fumes and sparks generated during cutting, so as to avoid affecting the working environment and the health of workers.

[0003] A Chinese patent application (or patent) with publication number CN218694409U discloses a protective device for metal cutting, including a base, a first housing fixed to the top of the base, a second housing fixed to the top of the first housing, a connecting block fixed to the front side of the bottom of the second housing, a hydraulic rod fixed to the bottom of the connecting block, a third housing fixed to the lower side of the hydraulic rod, a motor fixed to the inner cavity of the third housing, a cutting blade fixed to the output shaft of the motor, and a protective cover fixed to the front side of the third housing. The top of the protective cover has several ventilation holes. When using the cutting blade to cut metal (such as iron), this utility model can block the flying sparks by setting up the protective cover, and the operator can use an air pump to suck up the generated smoke and spray water on the smoke to achieve a purification effect. After spraying, the water can also be recycled and reused.

[0004] The aforementioned protective device for metal cutting includes a first housing. Fumes generated during cutting are drawn into the first housing via an air pipe and suction cup, and then flushed by a circulation mechanism within the housing. However, during the flushing process, because the fumes contain a large amount of particulate matter, some of it floats on the water surface. This can easily cause nozzle blockage and pump damage when reusing this water, resulting in poor purification. Furthermore, while a protective cover is installed to shield sparks, this cover is suspended above the cutting station. During actual cutting, sparks are angled backward, limiting its protective effect. Additionally, its non-adjustable height can interfere with the cutting operation. Therefore, we provide a protective device for metal cutting to address these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a protective device for metal cutting. By using a purification component, the fumes generated during cutting can be purified, avoiding the waste of water resources and incomplete purification caused by using water spraying. By using an adjustment component, the protective cover can be moved to any position within the fixed frame to meet usage requirements, thus solving the problems of existing protective devices for metal cutting.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
