DETAILED DESCRIPTION​​

[0034] The rivet cold heading process is disclosed.

[0035] The following will be described in detail with reference to the accompanying drawings. Figures 1-3 The application will be further described in detail.

[0036] The rivet cold heading process comprises the following steps:

[0037] Referring to Figure 1 , the rivet is produced by the cold heading device 1, and then is subjected to immersion treatment by the immersion device 2. The cold heading device 1 comprises a machine body 11 and a rivet outlet conduit 12. In the embodiment, the machine body 11 can be a cold heading machine. Compared with a large machine tool used in a traditional turning process, the machine body 11 has the advantages of lower cost and higher rivet processing efficiency. Therefore, the rivet is processed by the machine body 11, which can effectively reduce the production cost of the enterprise and help to improve the production and processing efficiency of the rivet.

[0038] Referring to Figure 1 , the immersion device 2 comprises an immersion box body 3 and a rivet guiding mechanism 4. The immersion box body 3 is fixed to the ground on the side of the machine body 11 by bolts, and the end of the rivet outlet conduit 12 away from the machine body 11 is arranged in the inner cavity of the immersion box body 3 and is welded to the immersion box body 3.

[0039] Referring to Figure 1 , in the embodiment, the inner cavity of the immersion box body 3 is used to contain immersion oil, which can be industrial lubricating oil. After the rivet enters the inner cavity of the immersion box body 3 through the rivet outlet conduit 12, it can be directly immersed in the immersion oil, thereby realizing the rapid immersion of the rivet.

[0040] Referring to Figure 1 , separation: the rivet is controlled to separate from the immersion position by the rivet guiding mechanism 4. The rivet guiding mechanism 4 can control the displacement of the rivet in the immersion box body 3, so that the rivet can enter or move away from the inner cavity of the immersion oil. The rivet guiding mechanism 4 comprises a rivet carrying plate 41 and a position guiding assembly 42. The outer peripheral size of the rivet carrying plate 41 is matched with the inner cavity size of the immersion box body 3, and the rivet carrying plate 41 is located on the inner bottom wall of the immersion box body 3 to carry the rivet entering the inner cavity of the immersion box body 3.

[0041] Referring to Figure 1The guide assembly 42 is used to control the reciprocating displacement of the rivet carrying plate 41 in the height direction of the infiltration tank 3. The guide assembly 42 comprises a guide motor 421, a guide screw 422, a bearing seat 423 and a preset supporting cylinder 424. In the embodiment, the bearing seat 423 can be a bearing seat, and the preset supporting cylinder 424 can be an internally threaded cylinder body which is threadedly connected to the guide screw 422. The rivet carrying plate 41 is provided with a recess, and the recess of the rivet carrying plate 41 is used for inserting and welding the preset supporting cylinder 424, so that the preset supporting cylinder 424 and the rivet carrying plate 41 are fixedly connected as a whole.

[0042] With reference to Figure 1 The guide motor 421 and the bearing seat 423 are welded to the two ends in the height direction of the infiltration tank 3. The output end of the guide motor 421 is arranged towards the bearing seat 423, and the guide motor 421 is located above the bearing seat 423. One end of the guide screw 422 in the length direction is connected to the output end of the guide motor 421 through a flange, and the other end is arranged on the bearing seat 423. When the guide motor 421 rotates in the output end, the guide screw 422 rotates in the clockwise direction, and the rivet carrying plate 41 can be displaced from the bearing seat 423 towards the guide motor 421 along the length direction of the guide screw 422, so that the rivet carrying plate 41 carries the rivet to be separated from the infiltration oil, and finally located above the infiltration oil.

[0045] With reference toFigure 1 , the nail outlet channel 31 is also arranged through the infiltration box 3, and in the embodiment, the highest liquid level of the infiltration oil is below the nail outlet channel 31. When the nail carrying plate 41 is lifted to the nail outlet channel 31, the nail carrying plate 41 is just below the output end of the nail pushing cylinder 44. At this time, the nail pushing body 452 pushes the rivet on the nail carrying plate 41 to pass through the nail outlet channel 31 and is discharged to the outside of the infiltration box 3 by the output end of the nail pushing cylinder 44.

[0046] Referring to Figure 1 and Figure 3 , the discharge: the rivet after infiltration is filtered and discharged by the nail outlet device 5. The nail outlet device 5 further includes a nail guide frame 51, a nail carrying filter screen 52 and an oil storage box body 53, wherein one end of the nail guide frame 51 in the length direction is obliquely welded to the outer wall of the infiltration box 3, the nail guide frame 51 is below the nail outlet channel 31, and the end of the nail guide frame 51 close to the infiltration box 3 is above the end of the nail guide frame 51 away from the infiltration box 3, so that the rivet is quickly displaced to the designated position through the nail guide frame 51.

[0047] Referring to Figure 1 and Figure 3 , the oil storage box body 53 is directly placed on the ground, and the oil storage box body 53 is below the nail guide frame 51 to receive the rivet transported on the nail guide frame 51.
