Description

A kind of sleeve and its manufacturing method

【Technical field】

The present invention relates to a sleeve and its preparation method.

【Background technique】

At present, the external structure of the sleeve is very diverse, including: Taiwan New Patent No. 79204521 "multi-faceted sleeve", No. 87200032 "sleeve structure improvement", No. 87111279 "used for sleeve identification Inserts", No. 88211814 "Sleeve Structure Improvement", No. 90206762 "Sleeve Structure Improvement", No. 90208985 "Sleeve Improvement" and other cases, which were respectively granted patents for the external structural design of the sleeve. , the most traditional form is to emboss the outside of the sleeve to form a ring-shaped embossing structure on the outside of the sleeve to increase the friction effect. Such a structure needs to be improved due to its very limited friction effect. . All the above-mentioned cases are patented respectively by enlarging the plane outside the sleeve for tool clamping action, or forming integral or segmented longitudinal lines outside the sleeve, among which, No. 88211814 "Sleeve Structure Improvement" ", which directly forms a concave-convex contact surface on the outside of the sleeve, and the sleeve structure of other cases is also to set a plane, an arc surface interval, or a continuous concave-convex tooth shape on the outside of the sleeve, or internal and external. The planar design of the multi-angle interval is the same or the arc surface of the corner end is equal, and no matter what kind of external structure it is, because its sleeve structure not only has the function of stopping the workpiece, but also has the function of being recognizable by the user. That is to say, on the surface of the sleeve, it is necessary to set the marking on the size or the printing of the trademark pattern. The above-mentioned sleeves are set on the surface, and most of the problems on the marking are not considered, and they cannot even be used for marking. There are actually improvements. necessary.

And because of its poor design and structure, it is inconvenient in construction, that is, when the general shape is particularly complicated, it is done by casting, and in the way of casting, its structural strength is very limited, and it must be cast. After heat treatment to strengthen its rigidity, it is also done by forging, and the forged structure must have a large structural surface and an uncomplicated structure. The objects that can be processed are limited and cannot cover complex structural forms; and There is also a direct embossing structure. When such a structure is embossed, its outer diameter is pressed inward at a single point, so it is easy to cause deformation or even rupture of the processing part. If it is precision casting , its cost is too high, so there is a need for improvement.

According to the physical characteristics of the workpiece itself, the maximum torque exerted by the sleeve (10) on the clamped workpiece is known, or the maximum torque value of the workpiece can be directly marked in the marking body (20), so that the user When driven by a wrench, you can immediately know the value of the torque that can be applied to avoid damage to the workpiece due to excessive torsion of the sleeve (10); and other information can be marked in the marking area (21) , including: the metric size of the actuated workpiece, etc., can also be changed according to different needs, and the size of imperial or metric or trademarks or other patterns can be set according to different needs.

And, the external configuration of the sleeve of the present invention is set as shown in Figure 4, and its production process (30) comprises:

Material selection (31): selecting different steel products or materials;

Forging (32): forging the shape of the hollow cylinder to form the embryo;

Coarse grinding outer diameter (33): coarsely grinding the embryo;

Teeth forming (34): the entire periphery of the initial blank is cut by multiple sets of external broaches to form a tooth shape, and the excess material is removed due to the force applied by the entire circumference of the broach to form a tooth-shaped part (110) and Spacer teeth (111);

Turning section (35); then through external circumferential turning to remove part of the teeth (110) to form the detent portion (11) still having teeth (110) and spacer teeth (111) ) and the marking part (12) of the planar arc surface;

Roller marking (36): the marking part (12) is set in a rolling manner as shown in Figure 4, and the ring-shaped continuous marking body (20) and marking area are directly formed on the overall marking part (12) (21), in which, the relevant size or trademark pattern is set in the sign body (20) in the interval triangular area and the non-triangular sign area (21), and the structure of the whole ring is set, and the metric and imperial systems coexist Structural form, it can be identified conveniently and quickly at any angle, and its marking part (12) forms a visual key point between the two detent parts (11), so its visual effect can be strengthened.

Hardening treatment (37): the overall heat treatment is performed to improve the overall hardness.

Fine grinding and polishing (38): polishing treatment for detailed surfaces;

Surface treatment (39): that is, electroplating, dyeing or related coating on the surface;

Finished product (390): complete finished product.

Through the aforementioned structural processing, the following advantages can be obtained, including:

1. Easy and quick to use: In use, the trigger parts (11) at both ends can be directly pulled, as shown in Figure 5, the sleeve (10) is to set the brake parts (11) at both ends Therefore, regardless of whether the user holds it at any end or at the center, it can provide effective friction performance, which is convenient and quick to use, and it is set with the interval tooth-shaped part (110) and the interval tooth-shaped part (111), The user can hold it in the manner shown in Figure 6, so that each finger falls on the tooth-shaped part (110) or on the spaced tooth-shaped part (111) to provide different friction forces, and it can also achieve friction detent effect.

2. Clear, fast and accurate identification: Since the marking part (12) of the sleeve (10) of the present invention is located between the detent parts (11), and is a complete ring design, the user can view it from any angle It is very fast and convenient to judge the marked patterns and characters. Moreover, the possibility of misjudgment will not occur, and the work efficiency will be improved. Moreover, the directivity of the tip of its triangular marking area (21,) can The clamping end of the sleeve (10) that cooperates with the workpiece can be clearly pointed out, so as to achieve rapidity of cooperation with the workpiece or the tool.

In addition, the structure of the embodiment shown in Figure 1 of the present invention is that the outer diameter of the driving end of the sleeve (10) is small, and it has a curvature shrinking deformation, so the detent parts (11) and the marking parts (12) at both ends The structural form of cooperation is to be located on the outer equal-diameter joint end of the matching tool, and when the sleeve (10) is a shape with a smaller diameter at the joint end and a larger diameter at the driving end, the detent parts at both ends of the present invention ( 11) The structural form of the central marking part (12) is also arranged at the driving end of the outer equal diameter; and when the sleeve (10) is an overall equal-diameter structural form as shown in Figure 7, it can be set as a whole Designs such as the central marking part (12) of the two ends of the catch part (11) of the present invention; The spacer teeth (111) can also be set as an arc-shaped straight spacer (112) as shown in the figure, for different users to choose, and the design of this straight arc It is also possible to modify the large-tooth-shaped catch part (11); in addition, thin necks of different lengths are formed at the outer ends of the two catch parts (11), as shown in Figure 9. The two ends of (11) directly form a short neck, which can also achieve the aforementioned functions.

Also as shown in Figure 10, the marking portion (12) of the present invention can also be provided with a ring-shaped marking body (120) on the outside, and a number marking body (20) and a marking area ( 21), can also be sleeved on the marking part (12) to achieve the purpose of marking, and can also be equipped with oblique cut grooves (121) on the marking body (120) to achieve elastic buckle on the marking part (12) In this way, the functions of the aforementioned items can all be achieved.
