Abstract

The invention discloses a spring installation end cover and a forming method thereof. The spring installation end cover comprises a sleeve and an annular protruding edge which is arranged on the sleeve in an extending mode. An axial cavity is formed in the sleeve. The annular protruding edge is arranged at one end, in the length direction, of the sleeve. The outer diameter of the sleeve is not larger than the inner diameter of a spring. The outer diameter of the annular protruding edge is not smaller than the outer diameter of the spring. The axial section of the annular protruding edge is spiral. A notch is formed in the annular protruding edge in the radial direction of the annular protruding edge. According to the spring installation end cover and the forming method thereof, the sleeve is sleeved with the wire spring, and the end of the wire spring is arranged in the notch; compared with the prior art, the structure is simple and reasonable, the wire spring is prevented from being affected when the annular protruding edge bears radial force, and accordingly the service life of the wire spring is prolonged, and mounting and dismounting of the wire spring are facilitated.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing, and in particular relates to a spring mounting end cover and a forming method thereof. Background technique [0002] At present, known springs are processed by metal wires, and the assembly and use of springs are elongated or compressed. In the compression type, they are divided into flat wire springs and round wire springs. However, when the round wire spring is used for compression, there are generally difficulties in installation and the round wire spring cannot withstand its radial force. [0003] Therefore, there is an urgent need for a spring mounting end cap and a forming method thereof. Contents of the invention [0004] In order to solve the above technical problems, the present invention provides a spring mounting end cap and a forming method thereof. [0005] In order to achieve the above object, technical scheme of the present invention is as follows: [0006] Th...
