Device for collecting automobile sheet metal polishing dust

Abstract

The invention discloses a device for collecting automobile sheet metal polishing dust, and relates to the field of automobile processing equipment. The device comprises a baseplate, wherein a dust collecting chamber with an opening in the upper end is arranged on the baseplate; partitions are longitudinally arranged in the dust collecting chamber, and divide the dust collecting chamber into independent dust collecting bins and negative pressure bins; a through hole used for communicating the corresponding dust collecting bin and the corresponding negative pressure bin is formed in each partition; a cover plate is arranged at the upper end opening of each negative pressure bin to form a closed cavity; two horizontally arranged cylindrical filter cylinders are mounted in each dust collecting bin, and fixed on the side wall of the dust collecting bin; a withdrawable dust collecting box is arranged at the bottom of each dust collecting bin. The device is high in dust removing efficiency, and has the advantages that all the units and parts are relatively convenient to maintain and replace, and the dust is relatively convenient to clean up; besides, the device is flexible to apply, so as to improve the dust collecting efficiency during sheet metal repair in a workshop.

Description

technical field [0001] The invention relates to the field of automobile processing equipment, in particular to a dust collection device for automobile sheet metal polishing. Background technique [0002] The metal dust and particles produced during the polishing process of automobile stamping sheet metal parts by pneumatic polishing machines are likely to cause harm to the human body. In order to ensure the health of employees, most of the dust collection devices in the rework area of ​​the stamping industry basically use upward suction centralized dust removal equipment. In actual use, the updraft dust removal equipment has the following disadvantages: [0003] 1. When using, the suction port should be aimed at the polishing place. At this time, the suction pipe occupies a certain space, which affects the polishing efficiency of workers. [0004] 2. The suction area of ​​the upward suction suction port is limited. When the raised metal dust is not in the suction area, it w...

AI Technical Summary

Problems solved by technology

[0003] 1. When using, the suction port should be aimed at the polishing place. At this time, the suction pipe occupies a certain space, which affects the polishing efficiency of workers.

[0004] 2. The suction area of ​​the upward suction suction port is limited. When the raised metal dust is not in the suction area, it will fall to the work surface under the action of gravity. The dust collection rate is only about 60%, and it falls on the grinding surface at the same time. The dust on the stage has also had a certain impact on the quality of parts and the health of employees
