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. Automatic arc start function, reliable work and good effect.
Airless Spray Gun
This process occurs when paint is applied to an object through the use of an air-pressurized Spray Gun. The Sprayer Gun has a nozzle, paint basin, and air compressor. When the trigger is pressed the paint mixes with the compressed air stream and is released in a fine spray.
Types of nozzles and sprays
Due to a wide range of nozzle shapes and sizes, the consistency of the paint can be varied. The shape of the workpiece and the desired paint consistency and pattern are important factors when choosing a nozzle. The three most common nozzles are the full cone, hollow cone, and flat stream.There are two types of air-gun spraying processes. In a manual operation method the air-gun sprayer is held by a skilled operator, about 6 to 10 inches (15–25 cm) from the object, and moved back and forth over the surface, each stroke overlapping the previous to ensure a continuous coat.In an automatic process the gun head is attached to a mounting block and delivers the stream of paint from that position. The object being painted is usually placed on rollers or a turntable to ensure overall equal coverage of all sides.
