The appearance of wires bent by hand is inconsistent, and the angle and length of wires bent by hand often deviate during installation, which affects the assembly and production quality. In addition, the efficiency of bending wires by hand is low. Utility Model Content

[0029] In view of the shortcomings of the prior art, the inventor of this case, through long-term research and extensive practice, has come up with the technical solution of this utility model. The following will further explain the technical solution, its implementation process, and its principles.

[0030] Example

[0031] like Figure 1-4The illustrated preferred embodiment of the device for multi-angle bending and forming positioning generally includes a base 14 with a fixing port 15 for fixing one end of an electric wire 17. A bending table 1 is also fixed to the base 14. Both the fixing blocks and the bending table 1 have three positioning surfaces, meaning the bending table 1 has three positioning surfaces 2, 3, and 4 facing different directions and located on the same plane. The electric wire 17 is placed sequentially on the positioning surfaces 2, 3, and 4 from the fixing port 15. The base 14 also has fixing blocks 5, 6, and 7 corresponding to the positioning surfaces 2, 3, and 4, respectively. The fixing blocks 5 press against the positioning surfaces. The wire 17 is placed on the 2, so that the wire 17 is formed into a given shape. The fixing blocks 6 and 7 fix the wire 17 placed on the positioning surface 3 and positioning surface 4, so that the wire 17 is first bent at the position of the positioning surface 4, and the bending degree here includes but is not limited to 90°. Then the clamping of the fixing block 7 is released, and the wire 17 is bent at the position of the positioning surface 3, and the bending degree here includes but is not limited to 90°. Thus, with the assistance of the device, the wire 17 can ensure the uniformity of the appearance of the extruded part and the bent part of the wire 17 after bending, so as to adapt to the spatial form of the power supply line 17 in the connector, and improve the quality and efficiency of subsequent assembly production.

[0032] Specifically, the movement of the fixing block 5 will be described in detail. The positioning surface 2 has a first graphic structure, and the clamping surface on the fixing block 5 has a second graphic structure. The fixing block 5 is slidably disposed on the base 14. The fixing block 5 can move linearly toward the positioning surface 2. When the fixing block 5 moves to the limit position close to the positioning surface 2, a first state is formed between the fixing block 5 and the positioning surface 2. The second graphic structure of the clamping surface on the fixing block 5 and the first graphic structure on the positioning surface 2 shape the wire 17 between them into a given form. The first graphic structure includes parallel and intermittent... The first protrusion 8 and the first recess 9 are spaced apart. The second graphic structure includes a second protrusion 10 and a second recess 11 arranged in parallel and spaced apart. When the fixing block 5 and the positioning surface 2 form a first state, the first protrusion 8 and the second recess 11 are engaged, and the first recess 9 and the second protrusion 10 are engaged. In this embodiment, the first protrusion 8, the second protrusion 10, the first recess 9 and the second recess 11 are all plate-shaped components. However, in actual use, any component that can compress the wire 17 to form an axially wavy shape can be regarded as the protected object of this utility model.

[0033] The fixed pressure block 6 is described in detail below. The fixed pressure block 6 is slidably mounted on the base 14 and can move linearly toward the positioning surface 3. The fixed pressure block 6 is also provided with a second bending guide structure 12, which is a cylinder with its axis parallel to the worktable surface. The fixed pressure block 6 has a clamping surface facing the positioning surface 3, and the second bending guide structure 12 is located on the clamping surface. When the fixed pressure block 6 moves to its extreme position close to the positioning surface 3, a second state is formed between the fixed pressure block 6 and the positioning surface 3, and the second bending guide structure 12 abuts against the positioning surface 3. At this time, the wire 17 is located between the second bending guide structure 12 and the base 14, and there is a gap between the fixing block 6 and the positioning surface 3. That is, the second bending guide structure 12 locks the fixing block 6 in the selected position, which can clamp the wire 17 between the second bending guide structure 12 and the base 14. The operator only needs to lift one end of the wire 17 upward to make the wire 17 bend around the second bending guide structure 12. The clamping of the gap can further ensure the stability of the wire 17 when bending, making it more convenient for the operator to bend the wire 17.

[0034] Similarly, the fixed pressure block 7 is slidably mounted on the base 14. The fixed pressure block 7 can move linearly toward the positioning surface 4. The fixed pressure block 7 is also provided with a second bending guide structure 13, which is a cylinder with its axis parallel to the worktable surface. The fixed pressure block 7 has a clamping surface facing the positioning surface 4, and the second bending guide structure 13 is located on the clamping surface. When the fixed pressure block 7 moves to the extreme position close to the positioning surface 4, a third state is formed between the fixed pressure block 7 and the positioning surface 4, and the second bending guide structure 13 abuts against the positioning surface 4. At this time, The wire 17 is located between the second bending guide structure 13 and the base 14, and there is a gap between the fixing block 7 and the positioning surface 4. That is, the second bending guide structure 13 locks the fixing block 7 in the selected position and can clamp the wire 17 between the second bending guide structure 13 and the base 14. The operator only needs to lift one end of the wire 17 upward to make the wire 17 bend around the second bending guide structure 13. The clamping of the gap can further ensure the stability of the wire 17 when bending, making it more convenient for the operator to bend the wire 17.

[0035] It should also be noted that the positioning surfaces are arranged around the circumference of the bending table 1, and the two adjacent positioning surfaces, namely positioning surface 3 and positioning surface 4, cooperate to form a first bending guide structure 23 for guiding the product to bend in a direction parallel to the workbench surface. When the second and third states are formed, the fixing blocks 6 and 7 clamp the wire 17 between the base 14 and the fixing blocks 7 respectively. At this time, the wire 17 will bend into a shape that matches the first bending guide structure 23 as it is clamped.

[0036] The base 14 is also provided with push-pull components 16 corresponding to the fixed pressure blocks 5, 6, and 7, respectively. The push-pull components 16 are used to drive the fixed pressure blocks 5, 6, and 7 to move in a straight line, thereby forming or exiting the first, second, and third states. The base is also provided with a guide structure 18. In this embodiment, the guide structure 18 includes, but is not limited to, a guide rail (groove structure). The guide structure 18 can also be a pipe-type component, which will not be described in detail here. At least a part of the fixed pressure block is embedded in the guide structure 18 and can move along the guide structure 18 to guide the fixed pressure block to approach or move away from the corresponding positioning surface. In this embodiment, the push-pull component 16 is a push-pull type quick-release mechanism. The quick clamp, namely the adjusting handle 19 and the adjusting rod 20, is connected to the adjusting handle 19 and the adjusting rod 20. The adjusting rod 20 is connected to the movable support block, which respectively drives the fixed pressure block 5, the fixed pressure block 6 and the fixed pressure block 7 to move along the guide structure 18. The push-pull assembly 16 of this utility model includes, but is not limited to, the push-pull quick clamp. Any component that can drive the fixed pressure block 5, the fixed pressure block 6 and the fixed pressure block 7 to move in a straight line is within the protection scope of this utility model. A connecting plate 21 is provided between the adjusting handle 19 and the base. The connecting plate 21 is provided with a plurality of mounting holes 22. The adjusting handle 19 and the base 14 are fixedly connected by the connecting plate 21 by means including but not limited to screw fixing.

[0037] It should be understood that the above embodiments are merely illustrative of the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
