Abstract
The utility model is related to improved welding and cutting equipment, in particular to an inlaid cutting torch nozzle, which is characterized in that a preheating oxygen branch pipe, a fuel gas branch pipe and a cutting oxygen passage which are built inside the main body sleeve of the cutting nozzle, are connected with the cutting nozzle via pipette tips; an opening carrier is inlaid inside the cutting nozzle, the inner sectional cavity thereof is the streamline shaped opening with non-solid cavity with surface galvanization treatment. The utility model is applied to flame cutting machines in rolled steel continuous casters to cut the rolled steel, the cutting slit reaches about 5mm, half of the conventional cutting slit, improving the utilization rate of rolled steel, saving the energy, reducing the energy consumption with fast metal cutting and good quality.
Description
The utility model is the improvement to welding and cutting device, is a kind of employing oxygen---combustion gas is a fuel, metal is carried out the inserted quick Cutting nozzle for cutting torch of instrument of flame cutting.
At present, the domestic flame cutting machine that in the steel continuous casting unit of metallurgy industry, uses, the cutting oxygen duct, core position of its cutting torch is adopted and is machined into cylindrical, the compound duct of pyramid type, can't eliminate the lapping defect between each shape face in process.When cutting work, these lapping defects have produced very big inhibition to swiftly flowing gas, influence result of use, cause the waste of great deal of steel.
The purpose of this utility model is in order to improve the utilization rate of steel, to cut down the consumption of energy, the flame cutting torch that uses in the steel continuous casting unit is improved, a kind of inserted quick Cutting nozzle for cutting torch being provided.
The inserted quick Cutting nozzle for cutting torch content Description of the utility model:
The inserted quick Cutting nozzle for cutting torch of the utility model is characterized in that: at built-in 20～60 combustion gas of the main body overcoat of cutting torch, oxygen channel---preheat oxygen bypass duct, combustion gas bypass duct and cutting oxygen path pipe are connected with cutting torch by the rifle head; Inlay a duct carrier in the cutting torch, its inner shape chamber is that streamlined duct is non-entity shape chamber, is divided into stable section, contraction section, throat, diffuser four parts, and the electroplating surface processing has been taked in streamlined duct.
The inserted quick Cutting nozzle for cutting torch of the utility model, be applied on the flame cutting machine that uses in the steel continuous casting unit of metallurgy industry, be used to cut steel, the cutting slot is little, can reach about 5mm, and only be 1/2 of conventional slot, can improve the utilization rate of steel, energy savings cuts down the consumption of energy, and Metal Cutting speed is fast, quality good, cut any surface finish, no undercut burns down dross, no carburetting and hardening phenomenon.Inserted quick Cutting nozzle for cutting torch long service life.
Embodiment:
Fig. 1 is inserted quick Cutting nozzle for cutting torch structural representation
The utility model is achieved in that sees Fig. 1, and among the figure: 1 is that preheat oxygen bypass duct, 2 is that overcoat, 3 is that rifle head, 4 is that cutting torch, 5 is that combustion gas bypass duct, 6 is the duct carrier for cutting oxygen path pipe, 7.
Cutting torch overcoat 2 is main bodys of cutting torch, also is the outer carrier in streamlined duct, and overcoat 2 built-in 42 combustion gas, oxygen channel---preheat oxygen bypass duct 1, combustion gas bypass duct 5 and cutting oxygen path pipe 6 are connected with cutting torch 4 by rifle head 3; Preheat oxygen bypass duct 1 provides preheated oxygen for each the gaseous mixture spray orifice on the cutting torch 4; In cutting torch 4, inlay a duct carrier 7, its inner shape chamber is streamlined duct, the less airflow design of resistance forms in the streamlined duct employing aerodynamics, be non-entity shape chamber, be divided into stable section, contraction section, throat, diffuser four parts, resistance is less when the oxygen flow passing hole channel, length increases, cylindricity improves, and it is more concentrated to reach the cutting oxygen flow, the purpose that penetration power is stronger; The electroplating surface processing has been taked in streamlined duct, has improved the anti-wear performance in streamlined duct, has reflected the radiations heat energy of part billet surface, has prolonged the service life of inserted quick Cutting nozzle for cutting torch.
