Description
Technical field
The present invention relates to a kind of carbon fibre composite process and remove material collection and dust pelletizing system, belong to engineered composite material processing technique field.
Background technology
The premium properties such as carbon fibre composite has that high-modulus, quality are less than aluminium, intensity is greater than iron and steel, corrosion-resistant, endurance, the fields such as the Aero-Space of military and civilian, automobile, machinery, chemical industry are widely used in, as structure, the functional material of Hi-Tech equipment.In the military equipments such as rocket, satellite, opportunity of combat and civilian large aircraft, wind power plant, nuclear power generating equipment, high-end auto parts etc., there is consequence.The application of carbon fibre composite parts, makes the structural strength of equipment and life-span obviously promote, and reduces weight, also play very important effect to energy-saving and emission-reduction.
The machining mode mainly drilling processing of carbon fibre composite part, in cutting process, due to its material behavior, the form removing material has obviously different from metal cutting process.The form of the material mainly chip that metal cutting is removed, and carbon fibre composite part cuts the form that the material removed is powder.There are some researches show, in metal cutting process except producing chip, also can produce dispersing of dust particle, there is very large pollution to surrounding devices and environment, the health for operator constitutes threat.And carbon fibre composite part cutting removal material is all powder morphology, and quality is light, is more prone to disperse and stick to lathe and other body surfaces, thus produces larger threat to surrounding devices, environment and operator's health; Carbon fibre composite part processing lathe is generally top grade, high speed and high-precision machining center, the micron-sized dust granules produced, machine tool chief axis and lathe inner body binding site can be entered, in machine tool high speed running, the destructive effects of grinding can be played between the components, affect precision and the service life of lathe; Carbon fiber powder is deposited in around machining area always, can enter the cutting zone between cutter and surface to be machined, due to abrasive action, can reduce the machining accuracy of part, increases surface roughness, reduces cutter life.And current most of lathe dust arrester used just plays the filtration of purification lathe inner air, be generally general dust arrester, can not collect the removal material of carbon fibre composite, the problem thus the dust that can not solve in carbon fibre composite drilling process disperses.Therefore the process of the collection and dust of removing material in carbon fibre composite part drilling process is had great importance.
Summary of the invention
