Description

Technical Field

[0001] The utility model relates to a spring forming device. Background Art

[0002] like Figure 8 As shown, the conical spring includes an upper spring end 61, a spring compression portion 62 and a lower spring end 63. The minimum inner diameter of the upper spring end 61 is smaller than the minimum inner diameter of the lower spring end 63. After the conical spring is produced, it needs to be compressed by a molding device to meet the specified size and mechanical performance requirements to ensure that the product meets the standards. However, in the actual compression molding process, there are the following problems: 1. The conical spring is placed in the upper and lower spring positioning seats. Due to errors such as large burrs on the conical spring, the conical spring is easily offset in the upper and lower spring positioning seats, resulting in inaccurate positioning, which affects the accuracy of spring compression; 2. During the operation of the equipment, the amplitude is large, which easily causes the conical spring to move during compression, posing a safety hazard; improvements and optimizations are made to address this.
