AI Technical Summary

Technical Problem

In the current heat treatment process of cutting teeth, when multiple layers are densely placed, the large temperature difference between the inside and outside and the uneven cooling result in inconsistent quality of the cutting teeth, posing risks of thermal stress and brittleness, and affecting performance stability.

Method used

A heat treatment system for cutting teeth is adopted, including a cutting tooth support frame and a cooling frame. Through an duct-insertion cooling structure, combined with a temperature detection and control system, convection cooling and precise adjustment are achieved to ensure that the cooling rate of each cutting tooth row is consistent.

Benefits of technology

It achieves uniform cooling rate of the cutting teeth, eliminates thermal stress, ensures uniform and stable batch performance, avoids brittleness and tipping risks, and improves processing quality.

Abstract

The application discloses a heat treatment processing system for a cutting tooth, which comprises a heating unit, a cutting tooth carrier, a cooling unit, a temperature detecting unit, a control system and a taking and placing unit. The cutting tooth carrier comprises a cutting tooth bearing frame and a cutting tooth cooling frame. The cutting tooth bearing frame is used for layer-by-layer bearing of the cutting teeth, and the number and distribution positions of the cutting tooth insertion stations on each bearing layer are the same. The cutting teeth inserted into the vertically corresponding insertion stations in each bearing layer jointly form a cutting tooth column. The cutting tooth cooling frame is used for placing the cutting tooth bearing frame, and a plurality of air pipes are arranged on the cutting tooth cooling frame in the vertical direction. The application can effectively solve the problem that the inner and outer temperature difference of the multi-layer densely placed cutting teeth is large during tempering and cooling in the existing heat treatment processing of the cutting tooth, the cooling is uneven, the cooling rate of all the cutting teeth is consistent, the secondary thermal stress is eliminated, and the batch performance is uniformly stable.
