How to choose the appropriate cutting nozzle model based on the thickness of the material
Flame CNC cutting machine Although its cutting range is much smaller than that of CNC plasma cutting, it is used for cutting cutting and cutting of medium and thick plate. Flame cutting has better cutting quality and lower processing cost. According to the general flame cutting parameters, the thickness of the carbon plate in the 6-200mm, carbon plate can be used to complete the general flame cut mouth, but Wuhan Bessie NC is still recommended here in the cutting of the material should be selected according to the thickness of the appropriate Cut the mold type to achieve the best cutting effect. The relevant parameter settings for flame cutting at different thicknesses are summarized below. The following are the same as the "

In the choice of cutting mouth models, we use the Shanghai gas welding machine factory production GK1 series fast cutting mouth, for example, in the cutting of 50mm thickness of the material generally selected 1-4 # cut mouth, 50-100mm is recommended to choose 4-5 # cut Mouth, more than 100mm thickness of the material was 6-7 # cut mouth. The reason is that different thickness of the plate should adopt different cutting speed, cutting gas pressure and different cutting nozzle models, plate thickness of 6-20mm due to heat susceptibility, at the beginning of cutting parts can not cut from the edge of the steel, and the use of Perforation method is the edge of the steel plate into a closed state, and the edge of the steel plate and the edge of the steel plate has a certain distance, which can limit the deformation caused by the size of parts deviation. For 20-100mm thick plate, due to the cutting is not prone to change and perforation operation slagging easy to plug the cut mouth, can be cut from the edge of the steel plate, thick plate in the NC automatic gas cutting often exist cutting surface is not enough Of the quality of the problem, therefore, in the thick plate before cutting should be cut out of the horizontal and vertical of the two incision, with a rectangular ruler to adjust the vertical direction of the torch, so that the cutting surface and the steel surface perpendicular. The following are the same as the "
In the industrial production and processing process, CNC flame cutting machine can cut a variety of shapes of parts, with strong versatility. Generally bear the sheet structure of the cutting material cutting, and structural parts of the cutting quality directly affect the workpiece welding quality and product performance. CNC cutting machine in the cutting application, not only fully reflects the cutting automation and centralized cutting the advantages of a significant increase in sheet utilization, but also cutting quality and production efficiency has been significantly improved. The following are the same as the "
Through the use of several cutting methods can be used to ensure that CNC flame cutting machine cutting various parts of the dimensional accuracy and cutting the high efficiency. The operator's high quality and operational skills are also related to the quality of CNC flame cutting machine cutting, is an important part can not be ignored.…
Use of torch and torch should pay attention to the main safety issues
(1) the use of torch and torch before the need to check the suction situation, the injection is not normal, must be repaired, the normal before use;
(1) the use of torch and torch before the need to check the suction situation, the injection is not normal, must be repaired, the normal before use;
(2) before the torch ignition, should check the connection and the tightness of the valve, the connection and the valve shall not leak; welding mouth, cut mouth shall not leak, blocked. Use the process, found torch, torch gas path and the valve has a leak phenomenon, should immediately stop the operation, repair and then use;
(3) is strictly prohibited in the oxygen valve and acetylene valve at the same time open the hand or other objects to block the tip or cut mouth;
(4) the tip or cut the mouth should not be too hot, the temperature should be placed too high water cooling;
(5) welding torch, torch gas channel structure must not sticky grease.…
CNC flame cutting machine cutting mouth cleaning
Generally do not automatically increase the operation, the operation of CNC cutting machine cutting the workers should always pay attention to the cutting distance from the cutting edge, when the steel deformation or uneven to be adjusted. When using propane or natural gas as the gas, cutting the thickness to 50mm, the cut mouth height should be doubled. If necessary, to be adjusted.

Another important factor in obtaining a good cutting surface is to set the correct spacing between the cutting tip and the workpiece. When the tip of the primary flame (flame core) is about 1 mm on the workpiece, it is the ideal spacing of the cut mouth, the distance of the cut mouth depends on the size of the cut mouth, with acetylene from 3 to 10 mm, with other gas from 6 a 12mm. The cutting head is easy to clog during the cutting process, and this time we need to clean the cut mouth.
When cutting the cut mouth, turn off the preheat oxygen hand valve; press the cut oxygen button to open the cutting oxygen solenoid valve; turn off the cutting torch on the torch so that the nozzle can be inserted into the nozzle, In the fast oxygen hole twist up and down, and slowly open the torch to cut oxygen hand valve, here, Wuhan universal era CNC Technology Co., Ltd. to remind customers, please use the manufacturer recommended cutting nozzle, the use of inappropriate tools Will cause the mouth of the injury.…
The basic concept of flame cutting nozzles
A metallurgical apparatus for cutting a nozzle for cutting a flame, characterized in that the preheated oxygen passage is an inverted cone and the gas passages inside the cutting nozzle are not in communication with each other, The annular cavity at the nozzle outlet. The utility model has the advantages of simple structure, safe operation and convenient operation, avoiding the flame cutting of the hot continuous casting billet, splashing the slagging and cutting the nozzle outlet gas (or preheating the oxygen) channel, preheating the oxygen back to the gas pipeline and tempering; To overcome the phenomenon of metal slab cutting, reducing the consumption of metal blanks.
