Description
Technical Field
The invention relates to the technical field of welding, in particular to a plasma air gouging system for air gouging of a cement roller.
Background
Plasma arc welding is a fusion welding method using a high energy density beam of plasma arc as a welding heat source. After the electric arc is subjected to three compression effects, namely a mechanical compression effect, a thermal compression effect and an electromagnetic compression effect, the energy is highly concentrated in an arc column with a small diameter, and the gas in the arc column is fully ionized into plasma, so that the electric arc is called a plasma arc. When the nozzle diameter is small, the gas flow is large and the current is increased, the speed of the plasma flame ejected from the nozzle is high, and the plasma arc is high in impact force, and the plasma arc is called as 'rigid arc' and is mainly used for cutting metal. On the contrary, if the plasma arc has small current and small impact force, the plasma arc is called as flexible arc and is mainly used for welding. Plasma gouging is a process in which when high-temperature and high-speed gas flow is sprayed at the nozzle of a plasma gouging machine, if current passes between an electrode in the nozzle and a workpiece, the gas forms a high-temperature plasma arc, the heat of the arc causes the local melting and evaporation of the metal workpiece directly opposite to the nozzle, and the molten metal is removed under the drive of the high-speed plasma gas flow. The cement roller press is a grinding device for cement production. The roller of the cement roller press has the problems of pits, bonding, abrasion and the like on the roller surface in the use process, so that the roller needs to be gouged and repaired. When the nozzle passes through the pits of the roller surface, the pits do not need air gouging, and if the pits of the roller surface are more, a large amount of energy is wasted; meanwhile, the pit can prolong the distance between the electrode and the workpiece, so that the electric arc is unstable, and the probability of arc breakage is increased. And if impurities such as cement are bonded on the surface of the roller, the current between the electrode and the workpiece is disconnected, so that arc breakage is caused. Because the roller is rotating during the gouging process, if the arc of the nozzle is broken, the roller needs to be reversed to determine the position of the roller for stopping the gouging if the arc cannot be found in time. If the nozzle stops working and then the nozzle is started again, the requirements of the gouging arc on voltage and air pressure are high, so that more time is consumed.
Disclosure of Invention
In view of the above, there is a need for a plasma gouging system for a cement roller gouging that reduces energy consumption and operates efficiently.
A plasma gouging system for cement roller gouging comprises a gouging module, a distance detection module, an arc striking module, a current or voltage adjusting module, a gas supply module and a control module, wherein the gouging module is used for gouging a roller of a cement roller press, the distance detection module is used for collecting distance information of a nozzle and a roller surface, the arc striking module is used for striking an arc for the gouging module, the current or voltage adjusting module is used for converting external alternating current into direct current used by the gas supply gouging module and the arc striking module and adjusting the current or voltage of a circuit where the gouging module and the arc striking module are located, the gas supply module is used for providing a gas source for the gouging module and the arc striking module, the gouging module, the distance detection module, the arc striking module, the current or circuit adjusting module, the gas supply module and the control module are electrically connected, and the control module sets a reference distance value, the distance detection module transmits the acquired distance signal between the nozzle and the roll surface to the control module, the control module generates a real-time distance value from the distance signal acquired by the distance detection module, and when the real-time distance value is larger than a reference distance value, the control module controls the current or voltage adjustment module and the gas supply module to break an arc of the gouging module, so that the gouging module stops working, and the arc striking module works; when the real-time distance value is smaller than or equal to the reference distance value, the control module starts the gouging module, arcs are started for the gouging module through the arc striking module, the gouging module generates high-temperature plasma arcs, and therefore the roller surface of the roller is gouged.
Has the advantages that: the plasma gouging system for gouging the cement roller comprises a gouging module, a distance detection module, an arc striking module, a current or voltage adjusting module, a gas supply module and a control module.
