Embodiment 1

[0036] In this embodiment, the stainless steel shell is combined with figure 1 , figure 2 As shown, it includes a material body 1, an annular groove 2 and a stopper 3, the annular groove 2 is arranged in the middle of the material body 1, and the bottom of the annular groove 2 protrudes toward the central axis to form two stoppers 3, and the two stoppers Sheet 3 is arranged symmetrically. Wherein, the material body 1 is provided with a tapered end 11 at an end away from the annular groove 2 , and an annular protrusion 12 is formed between the annular groove 2 and the tapered end 11 .

[0037] The above-mentioned stainless steel shell is made by a multi-station one-time cold heading forming process, combined with image 3 and Figure 4 , including the following steps:

[0038] (1) Feeding and cutting: the round steel wire is first straightened by the wire feeding wheel, and then cut into blanks (that is, the material body 1 in the finished product) by the cutter device. Th...

Embodiment 2

[0050] The setting and working principle of this embodiment are the same as those of Embodiment 1, the difference is that the billet after four times of stretching is translated or turned over and sent into the seventh cavity, and the small hole of the billet is through-holed so that the center of the billet The small hole is a through hole 4, and the through hole 4, the annular groove 2 and the material body 1 are coaxially arranged.

[0051] The finished product specifications are: shell outer diameter D 1 20.5mm, height 32mm, hexagonal width 13-15mm, height 3-6mm; ring groove 2 diameter D 2 12.3mm, depth 13mm, special-shaped hole (that is, the circle where the block 3 is located) diameter D 3 12.2mm, protrusion width 4-5mm, recessed diameter 10.5mm, through hole 4 diameter D in the shell 4 It is 8-9mm. According to the requirements of the applicable occasion, a through hole 4 can also be set in the annular groove 2. The setting of the through hole 4 is not directly proce...

Embodiment 3

[0053] The setting and working principle of this embodiment are the same as those of Embodiment 1, the difference is that: there is only one flap 3 for single-chip control.

Abstract

The invention relates to a stainless steel shell and a machining process thereof, and belongs to the technical field of machine element manufacturing. The stainless steel shell comprises a material body, a ring-shaped groove and a washer, wherein the ring-shaped groove is form in the middle of the material body; the bottom of the ring-shaped groove protrudes in the central axis direction to form the washer; and the stainless steel shell is formed by subjecting a to-be-machined blank to primary stretching, extrusion, secondary stretching, third stretching and fourth stretching. The machining process provided by the invention is applicable to machining of the stainless steel shell, a faucet tube and the like, and has the advantages of being high in machining precision, good in connecting fastness, and the like.

Description

technical field [0001] The invention relates to a stainless steel shell and its processing technology, which belongs to the technical field of machine element manufacturing. Background technique [0002] At present, the stainless steel shell is a commonly used mechanical component in the assembly process. It is usually used as a matching component on a machine or equipment. During the assembly process, the processing accuracy will affect the stability and firmness of the assembly, especially Assembling its key cooperation functions such as shift forks and gears, the conventional processing methods cannot meet the requirements of processing accuracy and processing strength. [0003] Based on this, this application is made. Contents of the invention [0004] In view of the above problems, the present invention firstly provides a stainless steel shell with high processing precision and high processing strength. [0005] In order to achieve the above object, the technical sc...
