Description
Technical field
The present invention relates to laser cutting auxiliary equipment field, be specifically related to a kind of scraper.
Background technology
In laser cutting process, cut material 11 surface is irradiated to after laser beam line focus, in order to auxiliary laser cutting, cutting head 12 is needed coaxially to blow, pressure-air or oxygen is adopted to be used as assist gas, as shown in Figure 1, when cutting head 12 lower surface distance cut surface is nearer, the material after partial melting is had can to run up to cutting head 12 inwall.As shown in Figure 2, the time is longer, and the waste material of accumulation can be more, and final dross 13 causes cutting head 12 blocked, stops the transmission of laser beam, causes cutting head 12 cisco unity malfunction.When cutting head 12 is taken off dredging, after dredging, need longer time adjustment cutting head 12 position; When adopting finer wire directly to dredge, because cutting head 12 opening size is little, internal cavities size is large, is therefore not easy to dispose being bonded in inner dross 13.
Summary of the invention
The object of the invention is to, a kind of expansion type automatic sharpening device for cutting head is provided, solves above technical problem.
Technical problem solved by the invention can realize by the following technical solutions:
For the expansion type automatic sharpening device of cutting head, comprise a scraper main body, it is characterized in that, described scraper main body comprises a scraping pipe, described scraping pipe adopts an intumescent tubular part, one end of described scraping pipe is provided with gas expansion parts, the air delivering pipeline of described gas expansion parts connection one for being connected with outside gas supply mechanism;
Described scraper also comprises a motor, and described motor is connected with described scraping pipe, drives described scraping pipe to rotate under the rotation of described motor.
When the present invention uses, air delivering pipeline is connected with outside gas supply mechanism, and cutting head is stretched in one end scraper being provided with gas expansion parts.Outside gas supply mechanism carries out air feed by air delivering pipeline to gas expansion parts, and gas expansion parts expand.Then connect motor, scraping pipe rotates under the rotation of motor, because the gas expansion parts of scraping tube end expand, therefore can with cutting head contact internal walls, the dross being bonded in cutting head inner wall surface is scraped and chips away.After scraping certain hour, turned off by motor, stop ventilation, gas expansion parts recover reset condition, take out scraping pipe.Present invention, avoiding tradition to scrape in slag and take off cutting head dredging and adopt finer wire directly to dredge Problems existing, achieve easily, convenient, simply scrape slag method, effectively improve in laser cutting process the efficiency of dredging cutting head.
Described scraper also comprises a pedestal, and described scraping pipe is vertically arranged on described pedestal, and described motor is connected with the one end away from gas expansion parts on described scraping pipe by described pedestal.
One section, the upper end vertically cutting of described scraping pipe, is divided at least three lobes to strut limb;
Be provided with an elastic bag in described scraping pipe, at least three lobes on described scraping pipe strut limb and described elastic bag as described gas expansion parts, and described elastic bag connects described air delivering pipeline.The present invention adopts the gas expansion parts of above-mentioned design, and structure is simple, with low cost.In use, outside gas supply mechanism is powered to elastic bag by air delivering pipeline, and elastic bag expands, and then at least three lobes are strutted limb struts, and venting pressure is larger, and the degree strutted is larger.When stopping ventilation, at least three lobes strut limb will recover home position.In addition, when elastic bag expands, at least three lobes strut the internal cavities size that limb can adapt to cutting head in elastic bag expansion process, under the rotation of motor, and then rotate, effectively dross are scraped from cutting head interior surface and chip away.
The top of described pedestal is also provided with a cutting head standing groove, and described scraping pipe is arranged on the bottom of described cutting head standing groove, and stretches out in bottom cutting head standing groove.When dross removed by needs, cutting head is placed in cutting head standing groove, during placement, aims at scraping pipe, scraping pipe is deep into cutting head inside, opens outside gas supply mechanism and motor can realize automatic dross object.Devise cutting head standing groove, can cutting head be fixed, when dross, more reliable and stable, also evenly can scrape off the dross of cutting head inside.
Described scraping inside pipe wall can also be provided with a pressure sensor, and described pressure sensor connects a microprocessor system, and described microprocessor system connects a display unit, and described display unit is arranged on described pedestal.When scraping pipe works, be placed in cutting head, user cannot see the elastic bag degrees of expansion in scraping pipe, therefore after being provided with pressure sensor on scraping inside pipe wall, when elastic bag expands, act on pressure sensor, pressure sensor sends pressure information to microprocessor system, after pressure information processes by microprocessor system, shown by display unit, so that user checks ventilation degree altogether, and then control the scraping degree to cutting head, avoid scraping pipe to scratch cutting head inside.
Microprocessor system, after processing pressure information, can be shown by force value, also can be shown by the animation of simulation three lobe scraping tube swelling state.
Beneficial effect: owing to adopting technique scheme, the present invention carries out dross action without the need to taking off cutting head, of the present invention simple to operation, can easily the dross being bonded in cutting head inside be disposed.
