Description

technical field [0001] The invention relates to the technical field of quenching equipment, in particular to an automatic quenching machine. Background technique [0002] The existing quenching method for pipe fittings is: heating the pipe fittings to a specified temperature, and directly cooling them in water or oil. This method is easy to cause the bending deformation of the pipe fittings, which affects the machining accuracy of the pipe fittings. The deformation error of the pipe fittings after quenching is difficult to correct, and can only be leveled by manual beating. Manual beating is time-consuming and laborious, and the beating process also produces large noise pollution. The beating method also directly affects the appearance quality of the product, and even generates internal stress, which is easy to break during use, making the pipe fittings unusable; and the box furnace is used for manual quenching, and the pipe fittings are manually clamped and immersed in the ...

This method is easy to cause bending and deformation of the pipe fittings, which affects the processing accuracy of the pipe fittings. It is difficult to correct the deformation error of the pipe fittings after quenching. It can only be leveled by manual beating, and manual beating is time-consuming and laborious. The beating process also produces large noise pollution. The beating method also directly affects the appearance quality of the product, and even produces internal stress, which is prone to breakage during use, making the pipe fittings unusable; and the box furnace is used for manual quenching, and the pipe fittings are manually clamped and immersed in the quenching water pool for quenching

This artificial quenching method has slow transfer time, high labor intensity and low work efficiency, and under long-term high temperature conditions, the clamps need to be replaced frequently, which increases the maintenance cost

In addition, due to the high quenching temperature of pipe fittings, safety accidents are prone to occur
