Embodiment 1

[0016] according to figure 1 , figure 2 As shown, a hole saw heat treatment process of this embodiment includes the following steps:

[0017] 1) Quenching: The workpiece enters the quenching furnace, and the quenching furnace is heated. The temperature of the workpiece is gradually raised to 650°C for 60 minutes, and the temperature of the workpiece is kept at 650°C for 15 minutes. Then continue to increase the temperature in the quenching furnace, and the temperature of the workpiece is gradually increased for 30 minutes. to 850°C, and keep the temperature of the workpiece at 850°C for 15 minutes, continue to increase the temperature in the quenching furnace, gradually increase the temperature of the workpiece to 1050°C in 30 minutes, and keep the temperature of the workpiece at 1050°C for 22 minutes, continue to increase the temperature in the quenching furnace, so that The temperature of the workpiece is gradually increased to 1220°C, and the temperature of the workpiece ...

Embodiment 2

[0023] A hole saw heat treatment process in this embodiment includes the following steps:

[0024] 1) Quenching: The workpiece enters the quenching furnace and is heated in the quenching furnace. The temperature of the workpiece is gradually raised to 600°C for 60 minutes, and the temperature of the workpiece is kept at 600°C for 15 minutes. Then continue to increase the temperature in the quenching furnace, and the temperature of the workpiece is gradually increased for 30 minutes. to 800°C, and keep the temperature of the workpiece at 800°C for 15 minutes, continue to increase the temperature in the quenching furnace, gradually increase the temperature of the workpiece to 1000°C in 30 minutes, and keep the temperature of the workpiece at 1000°C for 22 minutes, continue to increase the temperature in the quenching furnace, so that The temperature of the workpiece is gradually increased to 1200°C, and the temperature of the workpiece is kept at 1200°C for 30 minutes. Finally, t...

Abstract

The invention relates to a hole saw heat treatment process. Quenching and tempering operation is performed on a hole saw workpiece under a specific temperature at a specific time, the hardness of a hole saw subjected to heat treatment is made good, tempering is sufficient, the tenacity is good, and the service life of the product is greatly prolonged.

Description

technical field [0001] The invention relates to a hole saw, in particular to a hole saw heat treatment process. Background technique [0002] The hole saw is a cutting workpiece. Since the hole saw needs to be drilled, it has certain strength and toughness requirements to meet the drilling requirements. Therefore, the hole saw needs to be heat treated to improve the strength of the hole saw. The traditional heat treatment process has two There are many secondary carbides and poor hardness. Contents of the invention [0003] In view of the above shortcomings, the applicant has conducted research and improvement to provide a hole saw heat treatment process. [0004] The technical scheme adopted in the present invention is as follows: [0005] A hole saw heat treatment process, comprising the following steps: [0006] 1) Quenching: The workpiece enters the quenching furnace and is heated in the quenching furnace. The temperature of the workpiece is gradually raised to 600-...
