Description
Technical field
The present invention relates to the production plant field of carbon fiber, particularly a kind of high strength fibre shear.
Background technology
The free breaking length of ultra-high strength polyethylene in water is endless, when thickness is identical, the biggest quality that it can bear is 8 times of steel wire rope, be the third generation superhigh intensity fiber after carbon fiber, aramid fiber, all have irreplaceable effect in war industry and field of aerospace.Its important function is shellproof, anti-stab, and the traditional flak jackets of the flak jackets mass ratio made with it is light, and intensity is high.The strength ratio steel of this polyethylene fiber is high 15 times, if its strength ratio aramid fiber is high by 40% by mass, can be referred to as the polyethylene fibre that in the world today, intensity is the highest.
When shearing polyethylene fibre, then traditional cut mode be not applicable to.Tool strength must be greater than the intensity of polyethylene fibre, but the strength ratio steel of polyethylene fibre is high 15 times.If use common cutter to shear, this is very big to the wearing and tearing of cutter, and one only can shear cutter several times, and cutter life is extremely low, is unfavorable for producing in enormous quantities; And use that novel cutter material (as cubic boron nitride, diamond etc.) its intensity is high can be sheared, but poor toughness is not also at this fiber of applicable processing.
Laser cutting technique is widely used in the cutting of metal and nonmetallic materials, can greatly reducing process time, low processing cost, improves workpiece quality.Modern laser has become people institute to have fantasies of " double-edged sword " of " cutting through iron as if it were mud " of pursuit; For gold fortune laser c 02 laser cutting machine, whole system is made up of control system, kinematic system, optical system, water-cooling system, smoke evacuation and air blowing protection system etc., the numerical control pattern that Bian is advanced realizes multi-shaft interlocked and laser and does not cut by the homenergic of rate, supports the graphical formats such as DXP, PLT, CNC simultaneously and strengthens interface figure drawing modification ability; The inlet servo motor of Bian superior performance and transmission guide frame realize kinematic accuracy good at high speeds.
Laser cutting compared with traditional processing method, laser cutting its there is high cut quality, kerf width is narrow, heat affected area is little, otch is bright and clean; , high cutting speed, high flexibility, arbitrarily can cut arbitrary shape; The advantage such as adaptability for materials widely.Laser cutting is that the application technology that in Laser Processing industry, Dian is important has been widely used in automobile, rolling stock manufacture, aviation, chemical industry, light industry, electrical equipment and electronics, oil and metallurgical Deng Ding industry department owing to having various features.
Therefore, the present invention designs a kind of high strength fibre cutter, and it is main process apparatus with Laser Processing, solves the problems of the technologies described above and be significant in this area.
