Embodiment

[0026] The part processed in this example is a protective cover for protecting self-locking nuts. figure 1 is the front view of the part, figure 2 yes figure 1 left section view of image 3 yes figure 1 top view of Figure 4 is a 3D broken-out view of the part. Depend on Figure 1 to Figure 4 It can be seen that the part includes a cover body 1, and the cover body 1 is a cylinder with a closed top. Symmetrical ear pieces 2 are provided on both sides of the bottom of the cover body 1 , and fixing holes 3 are provided on the ear pieces 2 . During use, coat the anti-rust grease in the cover body 1 of the part, cover the self-locking nut to prevent the self-locking nut from rusting, and then pass the fixing hole 3 on the ear piece 2 of the part with a screw to connect with the substrate.

[0027] The part will have the following characteristics;

[0028] 1. The thickness of the part is only 0.8, which belongs to thin-walled parts.

[0029] 2. The lugs 2 ...

Abstract

The invention discloses a machining method for a protection cover part. The protection cover part is punched and formed through a J23-16T punching machine, and an elliptical or rhombus sheet is used for a protection cover part punching blank; the punching process is divided into cover forming, shaping and punching and edge cutting; the cover is formed through punching through a flange-free cylindrical tension die, and the cover is punched into a cylinder large in the outer diameter and low in height; a flange-free cylindrical tension die of different size is changed to be punched continuously to reduce the cover diameter and increase the cover height till the cover diameter and height approach the design sizes gradually to complete the cover forming stage; changing the shaping die, punching the diameter and the height of the cover into the final design size through a flange cylindrical tension die, punching flanges, and performing punching and edge cutting through a punching and edge cutting composite die. According to the machining method, the shaping quality is good, lubrication is performed without lubricants during tensioning, and annealing treatment is not needed during tensioning; processes can be shortened, dies are reduced, and the product efficiency is improved.

Description

technical field [0001] The invention relates to a processing method of a protective cover part, which belongs to the technical field of processing non-uniform flange deep cylindrical thin-walled parts. Background technique [0002] The part processed by the present invention is a protective cover for protecting the self-locking nut, and the part includes a cover body, which is a cylinder with a closed top. Symmetrical ear pieces are arranged on both sides of the bottom of the cover body, and fixing holes are arranged on the ear pieces. When in use, the cover body of the part is coated with anti-rust grease to cover the self-locking nut to prevent the self-locking nut from rusting, and then the screw is passed through the fixing hole on the lug of the part to connect with the substrate. The part will have the following characteristics; 1. The thickness of the part is only 0.8, which is a thin-walled part. 2. The lugs 2 on both sides of the cover body 1 are longer, while the...
