Abstract
The utility model relates to a mechanical and electrical integration plasma arc cutting machine, which comprises a main machine box and a cutting gun, wherein an insulated gate bipolar transistor (IGBT) inverting power source and a controller for controlling the work of the IGBT inverting power source are arranged in the main machine box. The mechanical and electrical integration plasma arc cutting machine is characterized in that a booster pump is further positioned in the main machine box, the booster pump and the IGBT inverting power source are independent with each other, an air inlet of the booster pump is arranged inside the machine box, an air outlet of the booster pump is connected with the cutting gun, and a booster pump power source is connected with the controller. The mechanical and electrical integration plasma arc cutting machine is simple in structure, easy and convenient in operations and flexible in moving. The mechanical and electrical integration plasma arc cutting machine can perform cutting operations without requiring compressed air allocated outside the machine box, and broadens the utilization range.
Description
Technical field
The utility model relates to and a kind of metal is carried out the cutting power supply device of cutting and separating, especially a kind of integral type plasma arc cutting cutting mill that can be applicable to that mobile place is novel.
Background technology
The plasma arc cutting power supply is accompanied by the manufacturing of the source of welding current and is born, existing up till now 100 years of development history.Enter after the sixties in 20th century, the appearance in succession of silicon rectifier cell, high power transistor (GTR), FET (MOSFET), igbt devices such as (IGBT), the development of integrated circuit technique and control technology, for the development of electronics plasma arc cutting power supply provides more wide space, wherein the most noticeable is invert plasma arc cutting power supply.Invert plasma arc cutting power supply is than long-pending little, in light weight, the energy-conservation province of traditional power frequency body material, and control performance is good, and dynamic response is fast.But existing plasma arc cutting power supply no matter power frequency form still is the inversion form, all need to join in addition the outer air compression plant of machine, otherwise the plasma arc cutting cutting mill just can't be worked.Therefore, when the workmen will carry out operation in other places, not only will mobile cutting machine, also to move external air compression plant, the inconvenience that this is suitable for the workmen simultaneously.In view of the foregoing, suddenly needing a kind of need connects power supply and need not the plasma arc cutting cutting mill of being convenient to move that extraneous Compressed Gas just can be implemented cutting work.
Summary of the invention
The purpose of this utility model is to solve existing the problems referred to above in the prior art, and a kind of novel plasma arc cutting cutting mill is provided.
The utility model is achieved in that electromechanical plasma arc cutting cutting mill, comprising: mainframe box and cutting gun.Be provided with the controller of IGBT inverter and the work of control IGBT inverter in the mainframe box, it is characterized in that: also be provided with booster pump in the described mainframe box, booster pump and IGBT inverter constitute two separate parts of electromechanical front and back, mutually noninterfere.Its air inlet is in cabinet inside, and the gas outlet is connected with cutting gun, and the power supply of booster pump is connected with controller.
The utility model has the advantages that simple in structurely, operate simple and easyly, convenient, need not just can implement cutting work, move flexibly, expanded the scope of application of cutting machine at the outside Compressed Gas that is equipped with of cabinet.

The specific embodiment
Because the continuous develop rapidly of technology of inverter, present inverter has High Power Factor, and it is more and more littler that the radiator structure of science, particularly volume are done, and these characteristics provide technical support for the improvement of present cutting machine structure.This product utilizes these characteristics exactly, under the roughly suitable situation of cutting machine volume, has arranged this mechanical part of booster pump in cabinet, has realized plasma arc cutting cutting mill electromechanical integration truly.The utility model is achieved in that integrated plasma arc cutting cutting mill, comprising: mainframe box, cutting gun.Be provided with the controller of IGBT inverter and the work of control IGBT inverter in the mainframe box, it is characterized in that: also be provided with booster pump in the described mainframe box, booster pump and IGBT inverter constitute two separate parts of electromechanical front and back, mutually noninterfere.Its air inlet is in cabinet inside, and the gas outlet is connected with the pneumoelectric interface of cutting gun by pipeline, and the booster pump power supply is connected with controller.
When starting the cutting button, controller is controlled inverter work on the one hand, simultaneously, makes booster pump running work on the other hand.During booster pump work, extract the air in the cabinet, handle, at last compressed air stream is sent into cutting gun through the booster pump compression.This moment, electrode left nozzle and the electric arc that ignites under the promotion of air pressure, and electric arc is compressed air again and takes nozzle out of, becomes non-transferred plasma arc at the rifle capitiform.When cutting gun when the workpiece, the melting of metal partly was compressed air-flow and blew off parent and form slot the thawing of the workpiece nozzle under high-temperature plasma arc moment.This product is placed on cabinet inside to booster pump, has solved that existing plasma arc cutting is confidential establishes the problem of air compression plant in addition in cabinet outside, thereby practical electromechanical integration plasma arc cutting cutting mill is come true.
Below only expressed embodiment of the present utility model, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model patent scope.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
The utility model has the advantages that simple in structurely, operate simple and easyly, convenient, need not just can implement cutting work, move flexibly, expanded the scope of application of cutting machine at the outside Compressed Gas that is equipped with of cabinet.
