Plasma classification and related knowledge Introduction 1, semi-automatic plasma, flame profile cutting machine, characterized in that the contour contact is placed in the guide hole of the guide sleeve, the compression spring is placed between the two, the torch is placed on the torch guide sleeve In the guide hole, the pressure spring is placed between the two, the torch is free to adjust its height under the pressure of the pressure spring, and the linear bearing slider under the lateral slide is matched with the linear bearing guide rail installed above the longitudinal slide, and the longitudinal slide is below The installed linear bearing slider is matched with the linear bearing guide rail installed on the main frame of the host machine. The advantages are reasonable design, convenient use, high processing precision, high cutting speed, saving raw materials, and being easy to promote and use. The fluidized bed dryer puts fluid materials such as powders, pastes (or even suspensions and solutions) on a perforated plate and other air distribution plates, and sends them into a drying medium with a considerable speed from the lower part. When the flow rate of the medium is low, the gas flows between the material particles, and the entire material layer does not move; gradually increase the gas flow speed, the material layer begins to expand, and the gap between the particles increases; then increase the gas flow speed, and a considerable part of the material is suspended. , Forming a gas-solid mixed bed, that is, a fluidized bed, because the suspended material in the fluidized bed is like a boiling liquid, it is also called a fluidized bed, and it presents fluid properties in many aspects. Therefore, the air flow speed is the most fundamental control factor of the fluidized bed dryer, and the appropriate air flow speed should be between making the material layer begin to fluidize and bringing the material out.

The plasma emitter in the plasma cutting machine electrode consists of a cerium/zirconium particle body and an outer surface silver plating layer. The bonding interface of the silver plating layer and the cerium/zirconium particle body is mechanical bonding or a thin alloy transition layer bonding. The utility model can be used in the electrode for plasma cutting machine to significantly improve the service life of the electrode for the plasma cutting machine, improve the cutting efficiency and cutting quality, and reduce the cutting cost.
2. An on-site rapid cutting and beveling tool used in the construction of pipelines. It can rapidly cut and groove the pipelines of various materials such as carbon steel, stainless steel, alloy steel, and cast iron. It can also be used for pipes of different diameters. Fast cutting and beveling on site. The device can be used for a variety of materials, a variety of different diameters; but also can be cut, but also bevel, with a variety of uses, it said multi-purpose pipe automatic cutting (groove) machine. At present, pipelines are cut and grooved at the site, gas (welding) cutting is commonly used for carbon steel pipes, and stainless steel and alloy steel pipes are cut with plasma. These methods have a rough cutting incision and are not easy to grind. There is no effective cutting method for cast iron pipes, and sometimes only manual sawing and wheel grinding are used. The utility model has a tensioning device to tightly put the machine chain on the pipeline, and the driving device drives the entire cutting (groove) machine to move along the chain along the pipeline so as to realize the cutting and the groove of the pipeline.
3, CNC plasma cutting machine, CNC machine tool equipment. It is composed of a frame, X-axis transmission mechanism, worktable, Y-axis transmission mechanism and cutting head components. Its structure is that the cutting head component is composed of a Z-axis transmission mechanism, a water system, and a plasma gun. The utility model combines the cooling water system and the gun head of the plasma gun organically, achieves the follow-up function of the cutting gun head through the lubrication of the water film produced by the cooling water, solves the instability factor of the domestic follow-up system, and greatly reduces the The cost of the follow-up system solves the problem of processing deformation of the thin plate and solves the phenomenon of burning black on the surface of the cut workpiece. The utility model has the advantages of novel structure, small investment, quick effect, convenient and flexible operation, and high reliability, and therefore belongs to a A new type of device integrating economy and practicality.
4. The plasma internal turbulent cutting torch has a conical turbulent flow reflow arc chamber, a flat end face or a concave cathode face, and a water-cooled cavity with a centrally-protruding "concave" shaped cathode. Its operating voltage is increased from 90 to 120V. To 160-200V, the utility model can greatly improve the power efficiency of the whole cutting machine, the cathode life is extended from 2 hours to 10 hours, and the cutting capacity is greatly enhanced. Under the same conditions, such as the cutting thickness and the cutting speed, the current domestic and foreign products Increase about 30 to 50%.
Plasma cutting torch cutting protection device, including insulation jacket, compacting ring, movable seat, fixed seat, steel wire, spring, gland, insulating jacket set on the torch, the compression ring on the insulating jacket step; The inner wall of the movable seat is in conformity with the tapered surface of the insulating jacket, and the upper inner wall of the fixed seat is attached to the movable seat; the fixed seat is connected with the pressure cover through the steel wire, and the spring is placed between the movable seat and the pressure cover. When the torch collides with the workpiece or obstacle to be cut, the protection device can play a role of damping and buffering, and the cutting torch of the cutting machine is not damaged.
5, automatic arc air plasma cutting machine, composed of the main power supply and cutting torch. The main power supply is a full-wave rectifier circuit composed of a transformer and a rectifier tube. An electrode 2, a connecting rod 7 and an electromagnet 9 are disposed along the longitudinal axis of the torch to be screwed, wherein the electrode is configured as a hollow tube closed at the front end, the diameter of the front end of the connecting rod is greater than that of the rear end, whereby the guide sleeve 6 with concentric arrangement is Between the formation of a cooling air flow space. In the torch handle 4 there is provided a control circuit board 20 for the arcing circuit, wherein the circuit board and the torch inner electromagnet 9, the coil 8, the pressure spring 10, the connecting rod 7 and the electrode 2 constitute an arc starting circuit.
