[0029] Example 1, the automobile spring forming machine, when in use, the raw material iron wire that needs to be folded into a spring is passed along the feeding block 6 and passed between the two feeding wheels 4, and the straightening mechanism 2 is started to work by setting the program of the automobile spring forming machine. The straightening mechanism 2 makes the iron wire into a spring and transports the spring to the receiving rod 12.

When the processing is completed, the first electric telescopic rod 11 is controlled by the automobile spring forming machine to move. The end of the first electric telescopic rod 11 will rise. At this time, the receiving rod 12 loses the support of the first electric telescopic rod 11. Through the action of the fixed shaft 26, the end of the spring will automatically droop because the end of the spring on the receiving rod 12 is longer and will automatically droop due to gravity. At this time, the processed spring will automatically enter the receiving box 14. When the collection of the springs is completed, the receiving box 14 is removed to complete the operation.
