Description

a sleeve

technical field

The utility model relates to a sleeve, in particular to a sleeve whose specifications and size marks are highlighted.

Background technique

Please refer to FIG. 7 and Annex 4. The traditional sleeve molding method is to first process a sleeve 50 by turning, so that the sleeve 50 has a large diameter portion 51 and a small diameter portion 52. The center of the sleeve 50 has a through hole 53 passing through the large-diameter portion 51 and the small-diameter portion 52, and then, at the position of the large-diameter portion 51 of the sleeve 50, the marking grooves of specifications and sizes are rolled out by rolling 54 (please refer to Annex 4 for details);

Surface electroplating treatment is carried out on the outer periphery of the large and small diameter parts 51, 52 of the formed sleeve 50 and the inner periphery of the through hole 53, so that an electroplating layer 60 is formed on the outer periphery and the inner periphery of the sleeve 50, so as to have a relatively Excellent anti-rust function (please refer to the photo of the actual sleeve on the right side of Annex 4);

Although this kind of traditional sleeve surface electroplating treatment method has the function of antirust, because there is a silver electroplating layer 60 on the mark concave groove 54, it is different from the electroplating layer on the large and small diameters 51,52 outer surfaces of the sleeve 50. 60 is the same color, when in use, it is extremely difficult to see the specification and size of the sleeve 50 shown by the marked concave groove 54 on the sleeve 50, which causes troubles in use.

In addition, there is a sleeve surface treatment method in which manganese phosphate penetrates into the sleeve 50. Although it also has the aforementioned anti-rust function, the sleeve after the manganese phosphate surface treatment is black as a whole (please refer to the attachment 4 shown in the actual product photo of the sleeve on the left side), the font on the mark concave groove 54 becomes fuzzy and unclear, and the aforementioned lack of use cannot be effectively solved.

Regarding the surface treatment methods of the above two sleeves, a printing method is derived to print fonts of different colors on the outer surface of the sleeve. Although it can solve the aforementioned problems of blurred and unclear fonts, this method After the sleeve has been used for a period of time, the printed font will peel off, or even be completely scraped off, which causes even more serious problems.

Contents of the invention

The main purpose of the utility model is to provide a sleeve that can highlight the specifications and dimensions of the sleeve so that users can see it clearly and operate it conveniently.

In order to achieve the aforementioned purpose, the utility model provides a sleeve, the sleeve has a through hole, and the outer peripheral edge of the sleeve has a black layer, and the outer peripheral edge of the sleeve has a marking concave The outer peripheral edge of the marked concave grain and the inner peripheral edge of the through hole respectively have an electroplating layer, so that the marking concave grain and the black layer form a silver and black pattern to highlight the marking concave grain.

The utility model will be described in detail below with specific examples in conjunction with the accompanying drawings.

Detailed ways

Please refer to Fig. 1 to Fig. 5. The utility model is a sleeve. The forming method of the sleeve includes: sleeve appearance forming, roll printing mark, surface electroplating treatment, surface grinding treatment, surface blackening treatment and Steps such as surface electric treatment, to complete the sleeve finished product of the present utility model (please cooperate and refer to shown in Fig. 1); Wherein:

In the sleeve appearance forming step: a sleeve 10 is formed by turning, the sleeve 10 has a large diameter part 11 and a small diameter part 12, and the center of the sleeve 10 has a through the large diameter part 11 and the through hole 13 of the small-diameter portion 12, and the outer peripheral edge of the large-diameter portion 11 has some anti-slip grooves 14 (please refer to FIG. 2 for cooperation);

In the rolling marking step: the set position of the large-diameter portion 11 of the sleeve 10 is rolled to print the set marking grooves 15, and the marking grooves 15 can be the specifications of the sleeve 10. , size (please refer to Figure 2 for cooperation);

In the surface electroplating treatment step: the outer peripheral edges of the large and small diameter parts 11, 12 and the inner peripheral edges of the through holes 13 of the sleeve 10 are subjected to surface electroplating treatment, so that the outer peripheral edge and the inner peripheral edge of the sleeve 10 form a plated surface. Layer 20, in order to have better anti-rust function and surface appearance (please refer to shown in Figure 3);

In the surface grinding treatment step: surface grinding is carried out on the outer periphery of the marked concave groove 15 of the sleeve 10, so that the electroplating layer 20 of the marked concave groove 15 is ground away (please refer to FIG. 4 for cooperation);

In the surface blackening treatment step: place the sleeve 10 in a manganese phosphate solution, and perform manganese phosphate treatment, so that the manganese phosphate solution can penetrate into the surface of the large-diameter portion 11 of the marking concave groove 15 without the electroplating layer 20, so that it forms A black layer 30 (please refer to Figure 5 and Annex 1 for further cooperation);

In the surface electrodeposition treatment step: use the surface electrodeposition treatment to form a protective film 40 on the outer periphery of the sleeve 10, so that it has better anti-rust function and beautifies the effect of the surface appearance (please continue to refer to Fig. 6 And shown in Annex 1), in this way, the surface treatment of the sleeve 10 can be completed.

Through the above surface treatment procedures, the molded sleeve 10 has a large diameter portion 11 and a small diameter portion 12, and the sleeve 10 has a through hole 13 in the center of the large diameter portion 11 and the small diameter portion 12, And the outer periphery of the sleeve 10 has a black dyed layer 30 infiltrated into the surface by manganese phosphate, the outer peripheral edge of the black dyed layer 30 is covered with a protective film 40, and the outer peripheral edge of the large diameter portion 11 has a number of non-slip grooves 14 , and the setting position of the large-diameter portion 11 has a marking groove 15 that can be the specification and size of the sleeve 10, the marking groove 15, the outer peripheral edge of the small-diameter portion 12 and the inner peripheral edge of the through hole 13 respectively There is an electroplating layer 20, so that the pattern of silver and black is formed between the marked concave groove 15 and the black dyed layer 30, so that the marked concave groove 15 is highlighted.

Please refer to Annex 1 and Fig. 1 and Fig. 5. Using the surface treatment method of the present invention, the formed sleeve 10 is not only formed on the outer peripheral edge of the small diameter portion 12 of the sleeve 10 and the inner peripheral edge of the through hole 13. An electroplating layer 20 with antirust effect, and the outer periphery of the large-diameter portion 11 of the sleeve 10 forms a blackened layer 30 of manganese phosphate, and the outer periphery of the blackened layer 30 is coated with a protective film 40, so that the entire sleeve 10 Has excellent anti-rust effect.

At the same time, it is worth noting that the sleeve 10 formed by the surface treatment method of the present invention has a silver electroplating layer 20 marking concave pattern 15 on the large diameter portion 11, and a black dyed black layer 30, so that Between the marking grooves 15 and the black dyed layer 30, silver and black forms are formed, so that the marking grooves 15 showing the specifications and sizes of the sleeve 10 can be seen by the user at a glance. Compared with the traditional surface treatment method, the sleeve formed by the utility model has a more obvious contrast (please refer to the attachments 2 and 3).
