Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of heat treatment, in particular to a heat treatment equipment and process for super-hard alloy hole saw. BACKGROUND

[0002] Heat treatment refers to a metal heat processing process in which a material is heated, kept warm and cooled to obtain the desired organization and performance in the solid state. Annealing, normalizing, quenching and tempering are the "four fires" in overall heat treatment. Quenching is a process in which a workpiece is heated and kept warm, and then rapidly cooled in water, oil or other inorganic salt, organic aqueous solution and other quenching media. Currently, during quenching of a super-hard alloy hole saw, there is a probability that impurities are precipitated from the super-hard alloy hole saw and remain in the cooling oil, and the cooling oil containing impurities can negatively affect the appearance and hardness of the super-hard alloy hole saw. Therefore, the impurities in the cooling oil need to be cleaned regularly.

[0003] Currently, when cleaning the impurities in the quenching pool, the impurities are mostly deposited at the bottom of the pool due to standing in the cooling oil. A filter screen is usually used to filter these impurities, but it is not convenient to clean the impurities fished out of the filter screen.

[0004] For example, a quenching tank for conveniently cleaning impurities in quenching oil disclosed in Chinese Patent Publication No. CN209307436U filters the impurities in the cooling oil, but when cleaning these impurities, the movable plate, filter screen and other parts need to be lifted out of the quenching tank together. There are motors, threaded rods and other parts above the movable plate, so it is not very convenient to clean the filter screen even if it is lifted out of the quenching tank.

The outer wall of the sliding block 3 42 is slidably connected to the outer wall of the sliding block 43. The inner wall of the sliding block 43 is slidably connected to the outer wall of the guide rod 3 44. A spring 5 can be fixedly mounted at the bottom of the sliding block 43. One end of the spring 5 is fixedly mounted on the top of the mounting plate 2.
