Description

Technical Field

[0001] This utility model relates to the field of additive manufacturing technology, specifically to a novel watch strap that is integrally formed using 3D printing. Background Technology

[0002] Metal watch bands are generally made of stainless steel or titanium alloy. Their durability, premium feel, and ease of cleaning make them a classic and versatile choice in the watch industry. Traditional metal watch band manufacturing processes include stamping, CNC milling, or casting. These methods first produce individual links and connectors, then assemble the links into a complete band using pins or screws. For mass production, stamping offers excellent cost-effectiveness. However, watches, especially high-end watches, are not only functional but also expressions of individuality and artistry, often requiring personalization and customization. Therefore, stamping and casting processes cannot meet these demands. While CNC milling can achieve high precision and complex designs, it is time-consuming, wastes a significant amount of metal, leading to high costs, and has limited production capacity. This is especially true when machining titanium alloy bands, where the cutting tool tends to stick, further increasing overall costs.

[0003] Metal 3D printing technology is an excellent choice for balancing production volume and personalization. Currently, with technological advancements and industry expansion, the cost of metal 3D printed products continues to decrease, especially in the production of titanium alloys. It can significantly reduce subsequent CNC machining and offers extremely high density and strength, perfectly meeting the production needs of high-end watch straps. Furthermore, the design flexibility of 3D printing technology allows for unique structures and appearances, creating a complete watch strap in one piece. This not only eliminates assembly processes but also enhances the texture and premium feel of the strap. However, traditional metal watch strap links typically use pins for rotation. This rotating structure inevitably creates numerous suspended areas during 3D printing, leading to warping and adhesion during powder sintering, thus preventing proper rotation.

[0004] In view of this, it is necessary for those skilled in the art to design a new type of watch strap that is 3D printed in one piece, which can achieve a rotatable structure through a new link unit and realize personalized design of structure and appearance. Utility Model Content

[0005] The purpose of this invention is to provide a novel watch strap that is integrally formed using 3D printing.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a novel watch strap integrally formed by 3D printing, which includes a watch strap connecting end and a watch strap body. The watch strap body includes several link units, each of which is provided with a connector and a groove. In adjacent link units, the connector on one link unit is engaged in the groove of another link unit, so that the two adjacent connectors form a chain connection structure, thereby making the adjacent link units form a movable connection structure.

[0007] Preferably, in this application, the watch strap is a titanium alloy watch strap.

[0008] Preferably, the connector has an angle with the horizontal plane, and the angle is 30° to 60°.

[0009] Preferably, the connector is a ring-shaped structure disposed on one side of the link unit.

[0010] Preferably, the connector comprises a semi-circular ring structure or a circular ring structure. A semi-circular ring structure is preferred.

[0011] Preferably, the link unit has a block structure.

[0012] Preferably, the link unit includes a prism structure and bosses disposed on the prism structure. The number of side faces of the bosses is the same as the number of side faces of the prism structure, and the side faces of the two in the same orientation are connected to form a dihedral angle. The connector and the groove are disposed on the side face of the prism structure. Preferably, the prism structure is a hexagonal prism; each of its six prism faces is provided with a connector and a groove.

[0013] Preferably, on one of the link units, a connector and a groove are provided on one side of adjacent link units.

[0014] Preferably, on one of the link units, the side of an adjacent link unit is not completely hollowed out, and the groove is embedded in the side and crosses with the connector on the side.

[0015] Preferably, the shape of the groove corresponds to the shape of the connector.

[0016] Preferably, the spacing between two cross-nested connectors can be adjusted by adjusting the depth of the groove and / or the radius of the connector, thereby adjusting the rotation angle of the front of the watch strap.

[0017] Preferably, the boss is located near the front of the watch strap, and the prism structure is located near the back of the watch strap.

[0018] Preferably, the angle of the dihedral formed between the side of the boss structure and the side of the prism structure, as well as the height of the boss, are adjustable to adjust the rotation angle of the back of the watch strap. The adjustable angle of the dihedral and the adjustable height of the boss mean that different angles of the dihedral and different heights of the boss can be obtained through parameter settings during 3D printing.

[0019] In the above text, the back of the watch strap refers to the side of the watch strap that is in contact with the wrist.

[0020] Preferably, the angle of the dihedral formed between the side of the boss structure and the side of the prism structure is 150°~180°, and the height of the boss is 0.3mm-0.7mm.

[0021] Preferably, the strap connection end is detachably connected to the watch face.

[0022] Due to the application of the above technical solution, the beneficial effects of this utility model are as follows: 1. This utility model improves the rotational freedom by changing the links of a traditional watch strap into independent small blocks as new link units, so that most of the overhang angles are greater than 40° during 3D printing. By adjusting the process parameters, the gap and roughness of the links are achieved, and finally a smooth-rotating titanium alloy watch strap is formed in one piece.

[0023] 2. This utility model can adjust the curvature of the front and back of the watch strap by adjusting the side angle of the boss in the link unit and the spacing between the connectors. By adjusting the shape and appearance of the link unit, customized design and personalized needs can be realized, and various shapes, sizes, textures, textures, hollowing and other diverse designs can be implemented. 3. This utility model produces a 3D printed one-piece watch strap through a simple structure, eliminating the subsequent assembly process of individual watch strap links. The density and strength of 3D printed titanium alloy are superior to traditional MIM or casting products, and the cost and material loss rate are lower than CNC machining, which improves production efficiency and quality and meets the needs of production and use.
