Description
Technical field
The utility model relates to the producing apparatus of hydraulic stem, refers in particular to a kind of producing apparatus of anti-corrosive type hydraulic stem.
Background technology
Hydraulic pressure of the colliery bar is the core component of widely used hydraulic support in coal mine.
Therefore the Main Function of hydraulic stem is supported weight, needs steel that the good ultimate compression strength of selectivity is high as its body material.The material great majority of manufacturing at present hydraulic stem matrix are to select 27SiMn.And the surface of hydraulic stem due to when work can and hydro-cylinder in sealing-ring produce scratching, so need to there be good smooth finish on the surface of hydraulic stem, otherwise can scratch sealing-ring, makes hydraulic support inefficacy; In addition, be in coal grain that the hydraulic stem of coal-face constantly can be splashed or even the shock of coal cinder, so the surface of hydraulic stem need to there is certain hardness, otherwise can be caused damage by knocking-on pit or pit; In addition, due to the heavy corrosion in coal mine, affect the work-ing life of hydraulic stem, therefore existing hydraulic stem surface all adopts the mode of chromium plating anticorrosive.
Therefore, that the core ultimate compression strength of hydraulic stem is wanted is large, will there be certain hardness, smooth finish and corrosion resistance in surface, the basic demand of Here it is hydraulic stem, and Given this, existing hydraulic stem is formed as base material+chrome faced mode manufacture by 27SiMn.
Existing hydraulic stem is used and scraps for 2 years at most, within 3 months of seriously corroded, must change, within average 1 year, must change once, this is due to the hydraulic stem surface of using at present, generally to use the mode protection against corrosion of chromium plating, and this protection against corrosion mode fails to reach the requirement for anticorrosion in Minepit environment far away.This is owing to existing a large amount of H in mine
2s, HP gas, moisture generation chemical reaction in these gases and mine generates sulfuric acid, phosphoric acid, chromium plating is a kind of technology of hydraulic stem matrix surface that chromium ion sticked to by chemical reaction, this is a kind of mechanical bond, sulfuric acid, phosphoric acid are by the gap infiltrate depression bar matrix surface of chromium ion, corrosive fluid depression bar.
At present in the equipment of common surface coating, surfacing equipment, plasma apparatus, thermal spraying apparatus can be surperficial at hydraulic stem by certain powder " paintings " or " gluing ", but these Technologies have shortcoming separately:
Built-up welding preservative coat and plasma cladding preservative coat are the etching problems that can solve hydraulic stem surface, but no matter are built-up welding preservative coat and plasma cladding preservative coat, all cannot solve heat conducting problem, and this is that process characteristic determines.The thermal conduction of built-up welding and plasma cladding is all very serious, while implementing these techniques, whole hydraulic stem is all that (severe patient reaches 1000 ℃ of left and right to hot state, burn red state---austenite), under this state, the toughness of hydraulic stem core has been suffered destruction, and the compressive property of hydraulic stem is declined rapidly, that is to say, built-up welding preservative coat, solved rot-resistant problem, but brought new problem simultaneously---hydraulic stem toughness declines;
The spraying bonding force of hot-spraying techniques is not strong, affects work-ing life.
