Industrial Front End: Flame Cutting Machine

The ancients said that if workers want to do good things, they must first sharpen their tools. When it comes to the social clock of today, this sentence is still a famous saying. The ancients do not deceive me. The society is always changing, and the same is true for the cutting machine industry. Details:/
Flame cutting machine is one of the main cutting equipment in CNC cutting equipment. In the cutting process, there are often problems such as poor cutting effect and large cutting gaps. There are many factors that cause these problems. The cutting oxygen flow rate, purity, oxygen flow shape, pressure, power of the preheating flame, composition of the metal to be cut, performance, surface condition, initial temperature, etc. will all influence the final cutting effect. The most significant and most significant The two factors are: the effect of flame cutting thermal expansion and the influence of the flame cutting path selection. However, many factors in the actual cutting process can artificially control the impact to the minimum.
In the actual cutting process, especially when the flame cutting machine cuts the parts, the temperature of the steel plate just when cutting is not high, which is similar to the indoor temperature, but the cutting speed of the parts is very fast, especially for the very small parts. After a part is cut, it is possible to have the same temperature as when it was not cut, or if it is only partially warmed, the size of the cut part is still relatively accurate. However, as the cutting time becomes longer, the number of parts increases, and there is a continuous output of heat, the temperature of the steel plate will continue to increase, resulting in thermal expansion. At this time, a compensation penalty Δt will be added to the slotting compensation k and the unilateral thermal expansion compensation. The trajectory changes and the part size does not deviate when it is cut. If you do not supply, the amount of thermal expansion of the steel plate will become larger and larger, the cutting trajectory will not change at the same time, and the dimensional deviation of the cut parts will also increase.
We, Kunshan Lieneng Automation Equipment Co., Ltd. is a company that independently manufactures various kinds of automation equipment. We sincerely invite major companies to join our flame cutting machine and join us on the road to success.
However, supplies should be replenished according to actual conditions. For parts with small differences in length and diameter, the expansion in all directions is basically the same, and it is only necessary to add a unilateral thermal expansion compensation Δt to the gap compensation k. For a large difference between the length and diameter ratio, the expansion amount in each direction is inconsistent, not only to add a unilateral thermal expansion compensation amount Δt to the kerf compensation k, but also to add a short-diameter unilateral thermal expansion to the kerf compensation k. The compensation amount Δt1 should be the total difference between the thermal expansion compensation amount in the long-axis direction and the thermal expansion compensation amount in the short-axis direction at the same time in the cutting program. Only by doing this can the dimensional accuracy of the cut parts be guaranteed.
Inexperienced employees will be unfamiliar with the control of thermal expansion of the steel plate. Cooling and cooling can be performed by physical cooling methods such as circulating cooling water and cooling fluid, and the amount of thermal expansion of the steel plate can be controlled to ensure the cutting of the parts of the CNC flame cutting machine. The accuracy of the size. However, the limitation of this method is that this method can only be used if the steel plate has little tendency to harden, or if the micro-hardening has little effect on the product quality.
The choice of cutting path also affects the size of the cut part. The poor choice of cutting path will affect the accuracy of the cutting parts. Impact on the cutting size and accuracy of the part is also the stiffness of the connection between the part and the steel plate.
The Chinese cutting machine has a long way to go, and we must rely on us all to break through. Details:/
