Description
Technical field
The utility model relates to NC flame cutting machine, is specifically related to a kind of NC flame cutting machine flame adjusting device.
Background technology
Existing NC flame cutting machine, the flow of flow control valve manual adjustments preheated fuel gas, preheated oxygen and the cutting oxygen of utilization assembling, after its flow is set up, whole flame cutting process is used strong and weak constant a kind of flame to complete.In actual mechanical process, particularly patch blanking processing, in order to increase work efficiency, that often the flow of preheated oxygen and preheated fuel gas is adjusted is larger, use relatively strong flame, to shorten, cut preheating time, but when cutting, can occur because flame temperature is too high the molten phenomenon of collapsing of cutting shoulder, affect cutting member quality, also cause the waste of oxygen and combustion gas simultaneously.If preheated oxygen and preheated fuel gas are adjusted to the flow while being applicable to cutting, can be multiplied preheating time, the raising of restriction production efficiency.Prior art discloses the NC flame cutting machine air regulating device of assembling flux-adjustable solenoid valve, this device is used for realizing remote-controlled gas and regulates, avoided each cutting flame adjustment all will arrive the advance trouble of line operate of cutting torch, but this device does not solve the problem that whole flame cutting process is used same flame.
Summary of the invention
The purpose of this utility model is for the problems referred to above, a kind of NC flame cutting machine flame adjusting device that can make NC flame cutting machine automatically complete strong, weak two kinds of flames conversion in cutting process is provided, thereby improves NC flame cutting machine production efficiency, saving oxygen and combustion gas, assurance cut quality.
For achieving the above object, the utility model adopts following technical scheme:
A kind of NC flame cutting machine flame adjusting device, comprise cutting torch and the preheated fuel gas carrier pipe being connected with this cutting torch, cutting oxygen carrier pipe, preheated oxygen carrier pipe, in described preheated fuel gas carrier pipe, be connected in series preheated fuel gas flow control valve, in described cutting oxygen carrier pipe, be connected in series cutting oxygen flow control valve, in described preheated oxygen carrier pipe, be connected in series preheated oxygen flow control valve, the described preheated fuel gas carrier pipe auxiliary preheated fuel gas carrier pipe that is connected in parallel, in this auxiliary preheated fuel gas carrier pipe, be connected in series an auxiliary preheated fuel gas flow control valve and an auxiliary preheated fuel gas magnetic valve, the described preheated oxygen carrier pipe auxiliary preheated oxygen carrier pipe that is connected in parallel, in this auxiliary preheated oxygen carrier pipe, be connected in series an auxiliary preheated oxygen flow control valve and an auxiliary preheated oxygen magnetic valve, described auxiliary preheated fuel gas magnetic valve is connected with electric control box by control cables with auxiliary preheated oxygen magnetic valve.
The utility model changes respectively an original road preheated fuel gas carrier pipe and preheated oxygen carrier pipe into two-way, by the magnetic valve of assembling, automatically realize the conversion of two-way air feed He Yi road air feed, thereby realize the automatic conversion of strong in NC flame cutting process, weak two kinds of flames, be that stronger flame is used in preheating, shorten preheating time, increase work efficiency; Relatively weak flame is used in cutting, guarantees cut quality, saves oxygen and combustion gas simultaneously.
