Abstract
Description
Technical Field
[0001] This utility model relates to the field of copper wire processing tooling technology, and in particular to a copper wire bending tooling. Background Technology
[0002] Bending is a common step in copper wire processing. Current technologies typically rely on manual operation or simple tooling, which has several shortcomings: First, the copper wire lacks a stable limiting structure during bending, making it prone to deviation and wobbling, resulting in low bending position accuracy and poor product consistency. Second, the bending angle is difficult to control precisely; the swing arm's amplitude depends entirely on the operator's experience, easily leading to excessive angle deviations within the same batch of products. Third, the tooling lacks versatility, failing to adapt to copper wires of different diameters and bending requirements; changing processing specifications necessitates replacing the entire tooling, which is cumbersome and costly. Fourth, the lack of a guiding structure during wire threading results in low threading efficiency and the threading position easily deviating from the preset path, affecting bending quality. Therefore, it is necessary to design a copper wire bending tooling that is precise in positioning, controllable in angle, highly versatile, and easy to operate to solve the above problems.

[0025] Turntable 2 is mounted on vertical plate 12. One side of turntable 2 is provided with bending column 1 3 and bending column 2 4. Bending column 1 3 is coaxial with turntable 2, and bending column 2 4 is off-axis with turntable 2. Bending column 1 3 and bending column 2 4 are spaced apart for copper wire to be threaded through.
[0026] Positioning block 5 is fixed on the vertical plate 12 and located above the bending column 3. The bottom side of positioning block 5 is set horizontally for limiting the top side of the copper wire.
[0027] Limiting plate 6 is mounted on vertical plate 12 and located below bending column 3, and is used to limit the copper wire after bending.
[0028] The swing arm 7 is fixed on the other side of the turntable 2 and is used to drive the turntable 2 to rotate.
[0029] like Figure 1 As shown, in an exemplary embodiment of this utility model, a limiting block 8 is also included. The limiting block 8 is fixed on the vertical plate 12 and is horizontally opposite to the bending column 3, and is used to limit the end of the copper wire.
[0030] like Figure 1 As shown, in an exemplary embodiment of this utility model, a guide block 9 is also included. The guide block 9 is fixed on the vertical plate 12. The guide block 9 has a guide hole 91, which is horizontally arranged and tangent to the top side of the bending column 3, for guiding the copper wire.
[0031] like Figure 1 As shown, in an exemplary embodiment of this utility model, the bending column 3, the bending column 4, and the limiting plate 6 are all provided with corresponding annular grooves for limiting the copper wire.
[0032] like Figure 1 As shown, in an exemplary embodiment of this utility model, the bottom side of the positioning block 5 is provided with a limiting groove arranged in the horizontal direction for limiting the copper wire.
[0033] like Figure 1 As shown, in an exemplary embodiment of this utility model, a connecting block 10 is also included. The connecting block 10 is fixedly mounted on the vertical plate 12 in an adjustable manner. The limiting plate 6 is rotated on the top side of the connecting block 10. The installation height of the limiting plate 6 can be adjusted through the connecting block 10, thereby controlling the bending angle of the copper wire.
[0034] like Figure 1 As shown, in an exemplary embodiment of this utility model, the swing arm 7 is provided with an adjustment hole 71, which extends along the length of the swing arm. The adjustment hole 71 is provided with a position-adjustable stop post 72, which interferes with the top side of the vertical plate 12 to limit the swing angle of the swing arm 7.
[0035] Therefore, this utility model has the following advantages:
[0036] Precise positioning: The positioning block (including the limiting groove), the limiting plate (including the annular groove), and the annular groove on the bending column form a multi-directional limiting structure, which can effectively limit the vertical and horizontal displacement of the copper wire during the bending process, solve the problem of inaccurate positioning of traditional tooling, and significantly improve the bending position accuracy.
[0037] Angle controllable: The position of the stop post on the swing arm can be adjusted through the adjustment hole, which interferes with the top side of the vertical plate to limit the swing angle of the swing arm, thereby controlling the rotation amplitude of the turntable and ensuring that the bending angle is consistent each time. This solves the problem of large angle deviation in manual operation and improves product consistency.
[0038] Easy to operate: The guide block guides the copper wire to be quickly threaded into place, the positioning block and limit block automatically limit the copper wire, and the swing arm drives the turntable to rotate to complete the bending. The overall structure is simple, the operation steps are few, and the processing efficiency is improved.
[0039] Reliable positioning: The positioning block limits the end of the copper wire to prevent over- or under-threading; the positioning groove of the positioning block, together with the bending column and the annular groove of the positioning plate, forms a three-dimensional positioning space to prevent the copper wire from undergoing axial or radial displacement during bending, thus ensuring the bending quality.
[0040] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model.
