[0005] The fixed seat is provided with a placing groove for placing the spring, the two ends of the placing groove are respectively extended to form an accommodating groove and a forming groove, one end of the placing groove close to the forming groove is provided with a stage, the stage is used for placing the hooks at the two ends of the spring, the forming groove is provided with a straight segment and an arc segment, the accommodating groove is used for placing the forming end of the spring, the fixed seat is provided with a bolt hole, the bolt hole is provided with a threaded pin, and the threaded pin extends to the outer surface of the fixed seat.

[0006] Further, the forming core rod is provided with a forming block at the front end, and is hinged to the placing groove by a pin, the middle segment of the forming core rod is provided with a movable insertion hole and is hinged to the threaded pin provided on the fixed seat, and the forming block is arc-shaped.

[0007] The spring is quickly positioned by the placing groove, the spring is opened and the straight segment is formed by the forming core rod, so that the straight segment of the spring can be quickly and accurately processed. Before forming, the spring is fixed in the forming device, the mechanism movement principle of the forming device is used to directly fold a very short straight segment structure at the end position of the spring hook, and then the forming method of the machine itself is combined to effectively solve the limitation of the machine, so that the structure that cannot be processed on the original machine can be smoothly realized, and the use demand of product on assembly part is met.

[0008] From the above description of the structure of the utility model, compared with the prior art, the utility model has the following advantages:

[0009] 1. The receiving groove can quickly position the spring, and the stage can place the hook end of the spring to be processed, which can quickly position it and also play a role in positioning for the molding process.

[0010] 2. Quickly achieve the forming of openings and straight segments. Attached Figure Description
