Problems solved by technology
[0002] The traditional force limiting rod assembly is completed through stamping dies and machining, which requires a variety of equipment and multiple processes to complete the production and processing. The cost of the entire process is very high, and it takes a certain amount of time, and there is a very high scrap rate. It is complicated and requires a lot of manpower, material resources and time, and the production efficiency is slow, which cannot keep up with the needs of customers and the production rhythm

Abstract
The invention relates to the technical field of force limiting rod machining, in particular to a force limiting rod assembly machining process. The specific technological process comprises the following steps: carrying out a first rough drawing process on raw materials; carrying out a first spheroidizing annealing process on the raw material after the first rough drawing; performing a second roughdrawing process on the raw material after the first spheroidizing annealing; carrying out a second spheroidizing annealing process on the raw material after the second rough drawing; performing a fine drawing process on the raw material after the second spheroidizing annealing; cutting finished wires after fine drawing into force limiting rod assembly raw material sections with a specified size;pressing the force limiting rod assembly raw material sections into a finished product of the force limiting rod assembly through four sets of cold forging dies; performing a surface treatment processon the finished product of the force limiting rod assembly; and detecting the shape of the finished product of the force limiting rod assembly after surface treatment, and packaging and warehousing the finished product after the finished product is detected to be qualified. Compared with the prior art, the force limiting rod assembly can be machined through cold heading dies and the surface treatment process, a traditional complex machining process is replaced, and the production efficiency is greatly improved.
