Too fast or too slow chamfering speed of cutting and chamfering machine is not conducive to ensuring the quality of the incision. Too fast chamfering speed of chamfering machine may cause an uncut phenomenon. Too slow chamfering speed of the cutting and chamfering machine will cause waste and melt the top of the incision. When they are together, a second chamfering machine is required.
Cutting Nozzle Model Of Cutting And Chamfering Machine
The type of cutting nozzle can be selected according to the thickness of the plate. The larger the number of cutting nozzles, the thicker the thickness of the steel plate that may be chamfered. The distance between the cutting nozzle should be that the flame core and the steel plate are on the same plane. If the cutting nozzle is too close to the steel plate, the cutting nozzle will be blocked; reduce.
A Detailed Description Of Chamfering Machine EF-80/AC
A computer controls reasonable chamfering machine chamfering program CNC cutting and chamfering machine to complete automatic chamfering machine chamfering, which recognizes the program, so the programming method of parts on the steel plate. The machining quality of chamfered portions plays a decisive role.
The influence of the chamfering order of cutting and chamfering machine refers to the order of chamfering machine chamfering for several nested parts on the steel plate. Generally, the principle of first inside and outside, preferably small and then large, should be followed; that is, the inner contour hole of the chamfering machine or the parts nested in the inner contour should be chamfered first, then the chamfering machine will chamfer the outer shape, and the chamfering machine will chamfer first.
For parts with a small corner area, the back chamfering machine chamfers large-sized parts; otherwise, the inner contour or other small parts will cause further deformation on the steel plate that has been separated from the motherboard and is not enough to maintain reliable positioning by its weight. , thus scrapped.
The influence of the chamfering direction of the cutting and chamfering machine correct chamfering order of the flat plate chamfering machine should ensure that the last cutting edge is separated from most of the motherboard if it is prematurely separated from most of the motherboard, the peripheral corner frame. It is not enough to resist the thermal deformation stress that occurs during the chamfering process of the chamfering machine, causing the chamfering parts of the chamfering machine to shift during the chamfering process of the chamfering machine.
The choice of the ignition point In general, the ignition point of the chamfering parts of the cutting and chamfering machine is ideal in the middle of the cutting seam of the chamfering parts of the outer chamfering machine on the edge of the steel plate.
The distance from the meeting will make the steel plate perforate, and the iron filings will splash, easily block the cutting nozzle and cause tempering, which will affect the quality of the cutting nozzle, reducing the life of the cutting nozzle and reducing the production efficiency. If the distance is too small, it will damage the cut parts and cause waste.
Selection of cutting method The most ideal introduction method is circular arc introduction, which is gradually approached along the tangent direction of the chamfering edge of the cutting and chamfering machine to achieve a smooth transition of the cutting section. The linear introduction is along the line direction of the cutting edge, and arc craters will appear at the introduction position, which will affect the appearance of the cutting, and will cause waste in serious cases.
The Thickness Of The Cutting And Chamfering Machine Is Different, And The Control Is Separate
The control of the chamfering quality of the thickness plate chamfering machine is different, and the plate thickness should adopt additional cutting and chamfering machine chamfering speed, chamfering machine chamfering gas pressure and other cutting nozzle models, thin plates with a thickness of 6-12mm are easily deformed due to heat.
When starting the chamfering parts of the cutting and chamfering machine, it is not necessary to cut from the edge of the steel plate but to use the perforation method to make the edge of the steel plate into a closed state. The slit of the edge of the steel plate has a certain distance from the edge of the steel plate, which can limit the parts caused by deformation. Dimensional deviation; for 20-100 thick plates, because the chamfering machine is not easy to deform when chamfering and the slag during the perforation operation is very easy to block the cutting nozzle, it can be cut from the edge of the steel plate, and the thick plate is often CNC automatic gas cutting. There is a quality problem of insufficient verticality of the chamfering surface of the plate chamfering machine.
Therefore, two horizontal and vertical incisions should be cut before the thick plate cutting and chamfering machine chamfering. A square ruler should be used to detect and adjust the two directions of the cutting torch. Verticality so that the chamfering surface of the cutting and chamfering machine is perpendicular to the surface of the steel plate.
Cutting And Chamfering Machine Manufacturer Teaches You To Pierce
Control the chamfering quality of the parts with holes cutting and chamfering machine. When the chamfering machine chamfering the legs with holes, the inner hole chamfering machine of the pieces should be chamfered first.
Then the periphery of the chamfering parts should be chamfered by the cutting and chamfering machine, which ensures the dimensional accuracy of the inner hole and its frame. Proper perforation can greatly reduce the time for cleaning the cutting nozzle and improve work efficiency. In addition, the diameter of the inner hole can be further reduced, and the thickness of the plate can be appropriately increased.
When perforating, to reduce the preheating time, the preheating oxygen should be appropriately increased (especially for medium and thick plates), select a reasonable perforation point, and observe the change of the preheating position of the steel plate. When the chamfering temperature of the cutting and the chamfering machine is reached (i.e. the ignition point), open the cutting and chamfering machine chamfering oxygen control valve and increase the speed appropriately until all the chamfering machine chamfering oxygen control valves are opened, and the perforation can be completed.
During the perforation process, pay attention to adjusting the speed and oxygen control valve so that the slag will fly out at approximately 40 degrees from the cutting nozzle. When the diameter of the inner hole is less than the thickness of the plate, it is not suitable to perforate cutting and chamfering machine chamfering, and the hole diameter should be machined; when the plate thickness exceeds 120mm, it is not ideal for perforation and chamfering machine chamfering.
The corresponding position is drilled with a 20mm chamfering machine chamfering hole by machining method, and then the inner hole chamfering machine chamfering is performed.
The above is the content of the cutting and chamfering machine. It will give you some little knowledge of popular science. I believe that friends should have a general understanding of it after reading it. There is a certain cognition for cutting and chamfering machine cognition or choice.
