Detailed Description

In order that the above objects, features and advantages of the utility model will be readily understood, a more particular description of the utility model will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model. The present utility model may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit of the utility model, whereby the utility model is not limited to the specific embodiments disclosed below.

As shown in fig. 1 and 2, a manual wire bending apparatus 100 according to an embodiment of the present utility model includes a base plate 10, a plurality of forming units 20, a bending actuator 30, and a fixing clip 40.

The base plate 10 is rectangular and has a certain thickness for loading the fixing and forming unit 20, the bending actuator 30 and the fixing clip 40.

The outer contour of one forming unit 20 forms a waveform 210 shape required after the wire 200 is bent. The plurality of molding units 20 are arranged in a row along the length or width direction of the base plate 10. For example, a plurality of molding units 20 are arranged along the length direction of the rectangular base plate 10 in the present embodiment.

The forming unit 20 includes a plurality of positioning pins, which are sequentially arranged at intervals according to a preset waveform 210 track, and the outer parts of which are used for winding the wire 200; the bending actuator 30 can be assembled with the positioning pin and relatively rotated, and the wire 200 can be forced to bend according to a preset shape by the rotation of the bending actuator 30; the fixing clip 40 is mounted on the base plate 10 and is used to fix one end of the wire 200.

In summary, implementing the technical solution of the embodiment has the following beneficial effects. When the wire manual bending forming apparatus 100 of the above-mentioned scheme performs the wave 210 bending process on the wire 200 (such as copper wire), firstly, one end of the linear wire 200 is fixed to the bottom plate 10 by the fixing clip 40, then the wire 200 is sequentially attached to each positioning pin, when each attaching to one positioning pin, the bending actuator 30 is assembled with the positioning pin, and then the bending actuator 30 is rotated along the track direction of the preset wave 210, so that the bending actuator 30 can squeeze and force the wire 200 to bend around the positioning pin, after the bending process at each positioning pin is completed, the wire 200 can form one wave 210 with a required shape and size, and the continuous wave winding process of the wire 200 can be realized by repeating this. Compared with the manual bending operation mode of workers in the prior art, the bending processing of the wire rod 200 can be rapidly and accurately performed by means of the cooperative matching and relative position precision of the forming unit 20, the bending execution device 30 and the fixing clamp 40, the bending forming processing difficulty is greatly reduced, and the consistency and quality of the waveform 210 of each wire rod 200 can be ensured.

It should be noted that, in order to save time for assembling and disassembling the bending actuator 30 with different positioning pins, so as to further improve the processing efficiency of bending the continuous wave form 210 of the wire 200, one bending actuator 30 may be configured for each positioning pin.

With continued reference to fig. 1 and 2, in one embodiment of the present utility model, the plurality of positioning pins includes a first positioning pin 21 and a second positioning pin 22, and a connection line between the first positioning pin 21 and the second positioning pin 22 forms a first diagonal segment 211. The plurality of positioning pins further includes a third positioning pin 23, and a line between the third positioning pin 23 and the second positioning pin 22 forms a first line segment 212. The plurality of positioning pins further includes a fourth positioning pin 24, and a connection line between the fourth positioning pin 24 and the third positioning pin 23 forms a second diagonal segment 213, where the second diagonal segment 213 is parallel to the first diagonal segment 211. The plurality of positioning pins further includes a fifth positioning pin 25, and a connecting line between the fifth positioning pin 25 and the fourth positioning pin 24 forms a third diagonal segment 214, where the third diagonal segment 214 and the second diagonal segment 213 are symmetrically disposed. The plurality of positioning pins further includes a sixth positioning pin 26, and a connecting line between the sixth positioning pin 26 and the fifth positioning pin 25 forms a second straight line segment 215, and the second straight line segment 215 is parallel to the first straight line segment 212. The positioning pins further include a seventh positioning pin 27, and a connection line between the seventh positioning pin 27 and the sixth positioning pin 26 forms a fourth diagonal segment 216, where the fourth diagonal segment 216 is symmetrically disposed with the first diagonal segment 211.

Thus, the first diagonal segment 211, the first straight line segment 212, and the second diagonal segment 213 constitute a first zigzag-like continuous segment, and the third diagonal segment 214, the second straight line segment 215, and the fourth diagonal segment 216 constitute a second zigzag-like continuous segment, and the two zigzag-like continuous segments are symmetrically arranged along the center line of the molding unit 20. The wire 200 is bent along the first positioning pin 21 to the seventh positioning pin 27 to form a sharp cone-shaped wave 210 pattern. At this time, any two adjacent segments of the waveform 210 are arranged at an inclined included angle, so that the waveform 210 is not easy to shift and loose relative to the positioning pin, and the quality of the bent waveform 210 is better ensured.

Of course, it should be noted that when the shape of the required waveform 210 is different, the number of the positioning pins and the arrangement structure of the positioning pins are adaptively adjusted, which is not described herein.

Furthermore, in some embodiments, the bend-performing tool 30 includes a handle 31 and a bending head 32, the end of the handle 31 being provided with a threaded section, the bending head 32 being provided with a threaded bore, the threaded section being threadedly received within the threaded bore. Therefore, the handle 31 and the bending head 32 are formed into a split structure, so that the storage is convenient, the handle and the bending head are connected by adopting a threaded structure, the assembly and the disassembly operations are simple, and the connection reliability is high. Of course, in other embodiments, the handle 31 and the bending head 32 may be detachably assembled by using a connection structure such as a buckle or a magnetic attraction.

The bending head 32 is also provided with a positioning hole 321, and the positioning hole 321 is used for being rotatably inserted with a positioning pin. The bending head 32 is sleeved on the positioning pin through the positioning hole 321, so that the mounting and dismounting difficulties are low, and the operability is high. However, it should be noted that the diameter of the positioning hole 321 is as equal as possible to the diameter of the positioning pin, so as to avoid the excessive deflection of the bending actuator 30 during rotation, which affects the quality and accuracy of the waveform 210.

Further, the bending head 32 is protruded with a circular boss 322 toward the side of the bottom plate 10. The outer circumferential surface of the circular boss 322 is used to abut the wire 200 so that the wire 200 is more easily forced to bend without damage to the wire 200.

In other embodiments, the fixing clip 40 is provided with a mounting hole 41 and a wire clamping groove 42, the fixing clip 40 is mounted on the base plate 10 through the mounting hole 41, and the wire clamping groove 42 is used for accommodating and clamping the wire 200.
