Problems solved by technology

The flame heating local annealing process is usually manually operated by experienced operators, which not only has high operating intensity and low production efficiency, but also has poor process stability and uneven heat treatment hardness
In particular, it is difficult to accurately control important process parameters such as heating distance, heating time and heating temperature during manual operation
For example, in the flame heating local annealing process, the temperature of the flame can only be determined by visual inspection, which not only requires the operator to be extremely experienced but also requires the operating environment to have very weak light. Sometimes the crimping end is burnt

Embodiment Construction

[0018] figure 1 is a schematic structural view of a crimping type workpiece according to an embodiment of the present invention. Please refer to figure 1 , the crimping-type workpiece 100 is, for example, a typical crimping-type connector used for wire harness crimping, and its material is tin bronze (QSn4-3). The crimping workpiece 100 includes a main body 101 and a crimping portion 102 connected to the main body 101 . In this embodiment, the crimping part 102 is substantially cylindrical and has an inner cavity 103 for accommodating the wire harness for crimping after heating and annealing. In this embodiment, the outer diameter D1 of the crimping portion 102 is about 1.7 mm, and the length L1 of the crimping portion 102 is about 5.45 mm.

[0019] Hereinafter, the heat treatment method of the pressure-bonded workpiece 100 using the high-frequency induction heating annealing process will be described in detail below.

Abstract

The invention relates to a heat treatment method for a compression joint type workpiece, which is applicable to the compression joint type workpiece comprising a main body and a compression joint part connected with the main body. The method comprises the following steps: sleeving a high frequency induction heating coil on the compression joint part of the compression joint type workpiece; heating the compression joint part by using the high frequency induction heating coil; and performing cooling protection on the main body of the compression joint type workpiece by using cooling protection water while conducting thermal annealing on the compression joint part. According to the heat treatment method for the compression joint type workpiece, the heat treatment efficiency and the quality of the compression joint type workpiece are improved.

Description

Technical field [0001] The invention relates to a heat treatment method, and in particular to a heat treatment method for a crimping workpiece. Background technique [0002] Crimp-type workpieces such as crimp-type connectors are mostly used in wire harness crimping. At the earliest, crimping-type workpieces were directly crimped without any treatment, which often resulted in frequent quality accidents of crimped end cracking, which not only affected the production schedule but also brought huge economic losses. After production practice and repeated tests, technicians found that local annealing treatment on the crimping end of the crimping type workpiece can effectively improve the crimping performance and reduce the occurrence of cracking quality accidents at the crimping end. [0003] At present, the local annealing of the crimping type workpiece generally adopts the flame heating local annealing process. The flame heating partial annealing process is usually manual...
