Description
Technical field
The utility model relates to a kind of flexible type through hole cap for the dredging cutting head, and is particularly a kind of for the flexible type manual through hole cap of dredging Laser Processing with cutting head.
Background technology
Laser cutting technique cuts down finished cost owing to have minimizing process time, improves the advantage of workpiece quality, be widely used in the processing of metal and nonmetallic materials, and Laser cutting also has the trend that replaces conventional tool gradually.
Laser cutting is to use the high power density energy that produces behind the Laser Focusing to realize.Under the control of computer, make the laser instrument discharge by pulse, thereby output-controlled repeat high-frequency pulse laser, form certain frequency, the light beam of certain pulsewidth, this pulse laser beam also focuses on by focus lens group on the surface of processing object through light path conduction and reflection, forms one by one trickle, high-energy-density hot spot, focal spot is positioned near to be processed, with moment high temperature melting or the gasification machined material.Each high-octane laser pulse moment just sputters a tiny hole to body surface, under computer control, laser Machining head and machined material carry out continuous relative motion by the figure of painting in advance to be got ready, will be processed into the shape of wanting to object like this.During cutting, one is sprayed by cutting head with the coaxial air-flow of light beam, the material of fusing or gasification is blown out by the bottom of otch (annotate: if the gas that blows out and be cut the reaction of material production thermal effect, then this reaction will provide cutting required additional source of energy; Air-flow cools off cut surface in addition, reduces the heat affected area and guarantees the not contaminated effect of focus lamp).Compare with traditional method for processing sheet material, it has high cut quality (kerf width is narrow, the heat affected area is little, otch bright and clean), high cutting speed, high flexibility (can arbitrarily cut arbitrary shape), the advantage such as adaptability for materials widely laser cutting.
In the laser cutting process, shine after the laser beam line focus and be cut material surface, for the auxiliary laser cutting, need the coaxial air blowing of cutting head, adopt pressure-air or oxygen as assist gas, see Fig. 1, when the cutting head lower surface is nearer apart from cut surface, have the material behind the partial melting can run up to the cutting head inwall, the time is longer, and the waste material of accumulation can be more, finally cause cutting head blocked, stop the transmission of laser beam, cause the cutting head cisco unity malfunction, see Fig. 2.When cutting head was taken off dredging, the time that needs after the dredging to grow was adjusted the cutting head position; When adopting finer wire directly to dredge, the adhesion strength that is accumulated waste material and cutting head is limit, and is not easy dredging.
