A kind of cross beam of laser cutting machine part
Technical field
The utility model belongs to laser process equipment field, more specifically to a kind of cross beam of laser cutting machine part.
Background technology
The incision principle of laser cutting machine is the laser that will launch from laser, through light path system, is focused into high power
The laser beam of density, laser beam is irradiated to workpiece surface, workpiece is reached fusing point or boiling point, while the high pressure gas coaxial with light beam
Body will melt or gasified metal is blown away, with the movement of light beam and workpiece relative position, finally makes material formation joint-cutting, so as to reach
To the purpose of cutting.Laser cutting is that traditional mechanical blades are instead of with sightless light beam, high with precision, and cutting is fast
Speed, is not limited to cutting pattern limitation, and Automatic Typesetting saves material, and otch is smooth, the low feature of processing cost.
It is at most planer type structure that Laser cutting, which is used, using more especially in terms of metal plate cutting.Due to swashing
The speed of light cutting is fast, especially the aperture of processing sheet when, it is necessary to acceleration of the cutting head motion with more than 1.5g up to
Degree, this quality to crossbeam has very high requirement.Crossbeam in initial laser cutting machine is welded using steel plate bending,
Beam not only weight weight, and welding deformation is also larger is moved, welding stress could will discharge within a certain period of time in addition, cause to swash
Light cutting machine does not embody due advantage in terms of performance.As technology constantly develops, in laser cutting machine industry
Progressively with casting aluminium or welding aluminium come working motion beam, use aluminum component production motion beam instead, although weight saving, make laser cutting
Machine is improved in performance, but welding aluminium and casting aluminium can only single-piece production, cost is too high, and the process-cycle compares
It is long, there is no obvious advantage in batch production process, be unfavorable for the batch production of laser cutting machine.
Therefore, new beam structure form is occurred in that now, i.e., it is using the disposable extrusion forming of aluminium alloy, such as Chinese
Number of patent application is:201510147747.4, publication date is:The patent document on July 8th, 2015, discloses a kind of laser and cuts
Cutting mill extruded aluminium crossbeam and production technology, mainly produce extruded aluminium Technology application to cross beam of laser cutting machine, due to
Extruded aluminium can infinitely extend, so after the completion of extruding, being cut off according to the length requirement that lathe is different;Due to extruded aluminium
Application condition is small in process, and general error is not more than 0.5mm, and the processing capacity subsequently reprocessed is smaller, saves processing
Time;Because extruded aluminium internal stress is smaller, sent out using lathe precision during long-time use will not be caused on lathe
Changing;Because the utilization rate of aluminium in extrusion process is higher, therefore material is saved, it is cost-effective.
And for example, Chinese Patent Application No. is:201620334702.8, publication date is:The patent text on October 12nd, 2016
Offer, disclose a kind of high speed laser cutting machine tool crossbeam, it includes:The cross-beam body of aluminium alloy extruded shaping, the cross-beam body
Middle part is provided with some through holes, and some through holes form latticed.The high speed laser cutting machine tool crossbeam of the program, it uses aluminium to close
Golden extrusion forming, with from heavy and light, inertia is small, and rigidity is strong, meets high speed laser cutting machine tool small, the speed of service that possesses movement inertia
The requirement for the features such as high and machining accuracy is high, the production cycle is shorter, and cost is relatively low.
The characteristics of above two scheme is shared is that crossbeam employs extrusion forming of aluminium alloy, compared to traditional welding or
Forging type, it has from heavy and light, and inertia is small, and the advantages of rigidity is strong, is a kind of nearly 2 years fast-developing technologies.Crossbeam is extruded
How shaping, the topmost cross sectional shape for being crossbeam rationally sets according to composite factors such as its installation requirements, intensity and weight
Meter, is that the section of beam shape of above two scheme is complex in place of key, is stranded relatively compared to common extrusion forming manufacture
Difficulty, and due to also needing to install the parts such as guide rail, rack on the crossbeam of laser cutting machine, the crossbeam blank after extruding is also needed to
Installation requirement is can be only achieved by progressive processing, and such scheme is for the processing relative difficult of crossbeam blank, and the process-cycle is relative
It is longer, it is difficult to ensure machining accuracy, therefore, is further improved.
The content of the invention
1st, the problem of solving
The crossbeam blank that extrusion forming of aluminium alloy goes out is used for existing laser cutting machine entablature, structure is relatively multiple
Miscellaneous, post-production is difficult, and the cycle is long, and the problem of precision is difficult to ensure, the utility model provides a kind of cross beam of laser cutting machine portion
Part, the cross sectional shape of optimization extruding crossbeam, under the premise of bulk strength is not influenceed, simplifies shape, saves material, draw high rear shape
It is stable, it is unlikely to deform, more mainly crossbeam blank post-production is simple, easily ensures compared with high manufacturing accuracy, it is ensured that guide rail, rack etc.
The installation accuracy of part.
