Studies Of CNC Surfacing Welding Machine Of Resistance To High Temperature And High Pressure Valve Sealing Surface

Resistance to high temperature high pressure valve sealing surface CNC weldingmachine is used to repair the valve sealing surface and surface enhanced equipment.Ordinary carbon steel in high temperature and pressure conditions of valves, life is short,and there are security risks. The wear resistance, corrosion resistance, high-temperature,high-performance alloy cowardly becomes expensive, such as cobalt-based alloy, if thevalve as a whole are using this alloy, high production costs, obviously unreasonable. Justthe valve sealing surface layer2~4mm high performance alloy can greatly improve thelife of the valve. For the above, this paper combined with existing equipment, weldingmachine machine control system design and writing software.In selecting welding method, the author compares the advantages and disadvantagesof various welding methods, considering using powder plasma arc welding, plasmawelding with powder cladding rate, dilution rate and good controllability process and soon. According to the requirements for surfacing, matching a good combination ofreasonable parameters, you can get high-quality surfacing.Welding machine CNC machine body design includes five parts, namely spindlemodule, moving the torch up and down the module, the module horizontal movementtorch, welding torch angle adjustment module, the torch straight swing module. Alsoincludes an optional powder feeder is also an important part. Master the use of the popularopen CNC system commonly used IPC+motion control card program, control cardmanufacturers to provide motion control function library development package, whichgreatly reduces the difficulty of developing the control system and shorten thedevelopment cycle, so that in a short time development of CNC welding systems possible.Welding machine CNC machine body design includes five parts, namely spindlemodule, moving the torch up and down the module, the module horizontal movementtorch, welding torch angle adjustment module, the torch straight swing module.
