A dust-free polishing device for metal products

Abstract

The invention relates to a dust-free polishing device of a metal product. The dust-free polishing device comprises a polishing system and a group of weak-current loop circuit systems, wherein the polishing system comprises a conductive polishing abrasive wheel and a to-be-processed metal product, which form a friction pair. Each weak-current loop circuit comprises a weak-current power supply, guide wires which are separately connected to a positive electrode and a negative electrode of the weak-current power supply and power connection heads which correspond to the guide wires in number; one end of each guide wire is connected to the positive electrode or the negative electrode of the weak-current power supply, and the other end of the corresponding guide wire is connected to the corresponding power connection head; and the power connection heads are electrically connected to the conductive polishing abrasive wheel and the to-be-processed metal product separately. The dust-free polishing device has metal dust which does not fly, avoids influence on health of a worker, avoids polluting environment, and avoids potential safety hazards such as combustion and explosion.

Description

technical field [0001] The invention relates to the technical field of surface polishing of metal products, in particular to a dust-free polishing device for metal products. Background technique [0002] In industrial production, especially in daily hardware processing, polishing is an important process that affects product quality; however, a large amount of dust is inevitably formed during the polishing process, which is extremely harmful to the human body, especially when it is not effectively controlled , can easily cause occupational diseases such as pneumoconiosis; and a large amount of dust pollutes the environment, resulting in potential safety hazards; at present, for the existing polishing dust problems, special treatment devices are mainly used, and there are deficiencies such as complex and expensive equipment, high assembly and site requirements, and most The actual characteristics of the dust were not considered in the design of the equipment; since 80%-90% of ...

[0002] In industrial production, especially in daily hardware processing, polishing is an important process that affects product quality; however, a large amount of dust is inevitably formed during the polishing process, which is extremely harmful to the human body, especially when it is not effectively controlled , can easily cause occupational diseases such as pneumoconiosis; and a large amount of dust pollutes the environment, resulting in potential safety hazards; at present, for the existing polishing dust problems, special treatment devices are mainly used, and there are deficiencies such as complex and expensive equipment, high assembly and site requirements, and most The actual characteristics of the dust were not considered in the design of the equipment; since 80%-90% of the polishing dust is metal dust, for flammable materials such as magnesium and titanium, the temperature rises rapidly and the sparks are large during the polishing process, even if special dust removal is used The equipment is only for the recovery and treatment of dust. It cannot prevent the formation of dust, nor can it completely avoid the occurrence of safety accidents such as combustion and explosion.
