Abstract
The strengthening of the aluminum section drawing die is a method for prolonging the service life of the aluminum section drawing die, and is particularly suitable for improving the thermal wear resistance of H13 serving as a die material. At present, most of aluminum type die drawing materials used in China are H13. The existing die manufacturing process is that the processed die is subjected to heat treatment quenching, and after nitriding treatment, the die is poor in wear resistance, short in service life, high in die cost and high in cost in section bar factories. How to prolong the service life of the die is a problem to be solved. The invention increases the heat-resisting and smearing-resisting property of the aluminum material by the processes of nitriding, carburizing and vanadinizing. The service life is prolonged by more than five times. The problem of the aluminium alloy touch life-span short is solved. The benefit is improved.
Description
Technical field:
The present invention is a kind of method that improves the work-ing life of aluminium section die, and especially the moulding stock of Shi Yinging is the hot wear resisting property improvement of H13.
Background technology:
The aluminium type of China's use at present just drawing-die moulding stock is that H13 is in the great majority.Present mold production process is roughly the mould process heat-treatment quenching after the processing, handles at via nitride, and wear resisting property is poor, and work-ing life is short, and section bar factory is expensive big on die cost, the cost height.The life-span of how to improve mould is and problem to be solved.
Summary of the invention:
The present invention mainly is wear resistance and the hardness that improves the aluminium section die surface.The works better ability of the condition of high temperature, processed mould is carried out nitriding, carburizing and vanadinizing processing on its surface.Whole process is once finished simply.There is an external-heat crucible salt stove to get final product.
Specific implementation method:
With one of external-heat crucible oven, pack into and contain the vanadium agent in the inside, urea carbonate, and reductive agent and promoting agent, and workpiece adding back temperature is increased to 550 ℃-560 ℃ and is incubated.Come to determine soaking time as requested, some infiltration layers of time length will be more in principle, and concrete reaction is as follows:
