There are several columnar points 11 on the workbench 1, and the operator bends the copper wire around the columnar points 11 into a required shape.

[0003] The efficiency of manual bending is low. Due to the characteristics of the copper wire itself, if it is bent directly around the point, the copper wire will have a certain degree of rebound after bending, which will affect the production accuracy of the bending section. Summary of the invention

[0004] In order to improve the production efficiency of the bending section, the present application provides a copper wire automatic cutting and bending device.

[0005] The present application provides a copper wire automatic cutting and bending device adopts the following technical solution: A copper wire automatic cutting and bending device comprises a workbench and a copper wire transport mechanism, a wire pressing mechanism, a cutting mechanism and a bending mechanism arranged on the workbench, wherein the copper wire transport mechanism is used to transport the copper wire, the wire pressing mechanism is used to flatten the copper wire at a position to be cut, the cutting mechanism is used to cut the copper wire, and the bending mechanism is used to bend the cut copper wire segment; The bending mechanism includes a driving member 1, a first moving seat, and a first clamping cylinder, a second clamping cylinder, a preliminary bending assembly, a pin spacing assembly, and an end stretching assembly arranged on the first moving seat.

The first moving seat is provided with an avoidance groove for the copper wire to pass through and move. The first clamping cylinder is fixedly arranged on the first moving seat and is used to clamp the pin at one end of the copper wire segment. The second clamping cylinder moves on the first moving seat and is used to clamp the pin at the other end of the copper wire segment. The preliminary bending assembly is used to bend the copper wire segment clamped on the first clamping cylinder so that the other end of the copper wire segment is clamped by the second clamping cylinder. The two clamping pins of the first clamping cylinder and the second clamping cylinder are always parallel to each other. The pin spacing assembly is used to drive the second clamping cylinder to move so that the two pins of the copper wire segment are separated to a fixed distance. The end stretching assembly is used to stretch the end of the bent segment toward the side away from the cutting mechanism, and at the same time drive the bent segment to be unloaded.

[0006] By adopting the above technical solution, after the cutting mechanism cuts the copper wire, the first clamping cylinder clamps the copper wire, and the first movable seat moves toward the side away from the cutting mechanism. At this time, the copper wire segment to be bent is away from the long copper wire, which can reduce the impact of the bending operation on the original long copper wire; then the preliminary bending component first bends the copper wire segment into an amplitude in which the two pins are relatively close, and then the pin spacing component separates the two pins of the copper wire segment to a fixed distance, and finally the end stretching component stretches the end of the bent segment, which can reduce the degree of rebound of the copper wire after bending and improve the production efficiency and production accuracy of the bending segment.

[0008] By adopting the above technical solution, the copper wire passes through the first clamping cylinder and enters between the bending plate and the fixed column, and then the rotating table rotates, and the bending plate drives the copper wire to bend around the fixed column.

[0012] By adopting the above technical solution, when the two pins of the copper wire segment are separated to a fixed distance, the bending segment stands up and the stretching block is located between the two pins. At this time, the first cylinder drives the slide to move outward, and the slide drives the stretching block to move. At the beginning, the first clamping cylinder and the second clamping cylinder continue to clamp the two pins, and the stretching block stretches the end of the bending segment against the middle of the end, and then the first clamping cylinder and the second clamping cylinder release the two pins. At this time, the bending segment is hung on the stretching block and is taken out by the stretching block for unloading. After the stretching block slides to the limit and stops, the bending segment falls along the parabola under the action of inertia.

[0013] Preferably, a control member is further included, wherein the slide seat includes a first slider, an inclined block, a second slider and a first spring, the first slider being slidably connected to the first slide groove, the inclined block being fixedly arranged on the first slider and located on a side of the fixed block close to the bending section, an inclined groove being provided on the inclined block along an inclined direction, the second slider being slidably connected to the inclined groove, the first spring being located in the inclined groove, the two ends of the first spring respectively abutting against the top wall of the inclined groove and the top surface of the second slide groove, and the first spring being always in a compressed state; The fixed block is provided with a second slide groove on one side facing the inclined block, the second slide groove includes a transverse portion parallel to the length direction of the first slide groove and an inclined portion parallel to the inclined groove direction, the transverse portion is located above the inclined portion, one end of the second slider close to the fixed block is slidably connected in the second slide groove, and one end of the second slider away from the second slide groove extends out of the inclined groove and is fixed on the stretching block; The control member is used to drive the second slider to slide in the inclined groove.

[0015] By adopting the above technical scheme, when the preliminary bending assembly is running, the stretching block moves down to abut against the fixed column, which can press the copper wire that has escaped from the first gap back into the first gap. At the same time, during the period when the bending plate bends the copper wire, the stretching block can also play a certain restrictive role on the copper wire; when the pin spacing assembly is running, the second clamping cylinder drives one of the pins to move, so that the bending section automatically bypasses the fixed column and the stretching plate during the standing process, and then before the movable block stops running, the movable block acts on the first inclined surface to drive the third slider to move toward the side of the second slider, and finally the third slider abuts against the bottom of the second slider, and the second slider enters the horizontal part. At this time, the first cylinder drives the first slider to move outward, and the second slider follows the first inclined block and the first slider to move outward together in the horizontal direction, finally realizing the stretching of the end of the bending part by the stretching block and the blanking of the bending part.

In the process of bending the copper wire of the present invention, the preliminary bending assembly first bends the copper wire segment into an amplitude where the two pins are relatively close, and then the pin spacing assembly separates the two pins of the copper wire segment to a fixed distance, and finally the end stretching assembly stretches the end of the bent segment, which can reduce the degree of springback of the copper wire after bending and improve the production efficiency and production accuracy of the bent segment; 2. In the present invention, when the two pins of the copper wire segment are separated to a fixed distance, the bending segment stands up and the stretching block is located between the two pins.

[0034] Reference Figure 2 and Figure 3 The wire pressing mechanism 3 includes a pressing cylinder 31, which is arranged on one of the lead molds 21. Since the round shape is easy to slip and difficult to cut, the pressing cylinder 31 is used to flatten the copper wire to be cut, so that the round shape becomes other shapes that are easier to cut.

[0035] Reference Figure 2 and Figure 3 The cutting mechanism 4 includes a fixed seat 41 and two cutters 42. The fixed seat 41 is fixedly arranged on the workbench 1. The fixed seat 41 has a through hole for the copper wire to pass through.

The two pins clamped by the first clamping cylinder 53 and the second clamping cylinder 54 are always parallel to each other. The pin spacing assembly 7 is used to drive the second clamping cylinder 54 to move so that the two pins of the copper wire segment are separated to a fixed distance. The end stretching assembly 8 is used to stretch the end of the bent segment toward the side away from the cutting mechanism 4, and at the same time drive the bent segment to be unloaded.

[0038] Reference Figure 5-Figure 12 After the cutting mechanism 4 cuts the copper wire, the first clamping cylinder 53 clamps the copper wire, and the first movable seat 52 moves toward the side away from the cutting mechanism 4. At this time, the copper wire segment to be bent is away from the long copper wire, which can reduce the impact of the bending operation on the original long copper wire; then the preliminary bending component 6 first bends the copper wire segment into an amplitude in which the two pins are relatively close, and then the pin spacing component 7 separates the two pins of the copper wire segment to a fixed distance, and finally the end stretching component 8 stretches the end of the bent segment, which can reduce the degree of rebound of the copper wire after bending and improve the production efficiency and production accuracy of the bent segment.

A first gap 64 is left between the bending plate 63 and the fixed column 62 for accommodating the copper wire.

[0040] Reference Figure 5-Figure 8 The copper wire passes through the first clamping cylinder 53 and enters between the bending plate 63 and the fixed column 62 , and then the rotating table 61 rotates, and the bending plate 63 drives the copper wire to bend around the fixed column 62 .

When the two pins of the copper wire segment are separated to a fixed distance, the pin clamped by the second clamping cylinder 54 is located above the pin clamped by the first clamping cylinder 53.

[0042] Reference Figure 5 , Figure 6 , Figure 8-Figure 11 The first motor 72 drives the gear 73 to rotate, and the gear 73 meshes with the rack and moves along the rack, thereby driving the movable block 74 to slide along the arc track, and finally driving the second clamping cylinder 54 and one end of the clamped pin to move, and the end of the pin clamped by the second clamping cylinder 54 rotates upward, so that the bending section bypasses the fixed column 62 and presents a standing state.

[0043] Reference Figure 10-12 The end stretching assembly 8 includes a fixed block 81, a slide, a first cylinder 83 and a stretching block 84. The fixed block 81 is fixedly arranged on the first movable seat 52. A first slide groove 811 is provided on the fixed block 81. The slide is slidably connected to the first slide groove 811 along a transportation direction parallel to the copper wire. The first cylinder 83 is arranged on the fixed block 81 to drive the slide to move. The stretching block 84 is arranged on the slide. When the pin spacing assembly 7 drives the two pins of the bending section to separate to a fixed distance, the stretching block 84 is located between the two pins. The stretching block 84 has a rounded corner on the side of the end of the bending section.

[0044] Reference Figure 10-12 When the two pins of the copper wire segment are separated to a fixed distance, the bending segment stands up and the stretching block 84 is located between the two pins. At this time, the first cylinder 83 drives the slide to move outward, and the slide drives the stretching block 84 to move. At the beginning, the first clamping cylinder 53 and the second clamping cylinder 54 continue to clamp the two pins, and the stretching block 84 stretches the end of the bending segment against the middle of the end, and then the first clamping cylinder 53 and the second clamping cylinder 54 release the two pins. At this time, the bending segment is hung on the stretching block 84 and is taken out by the stretching block 84 for unloading. After the stretching block 84 slides to the limit and stops, the bending segment falls along the parabola under the action of inertia.

[0045] Reference Figure 10-12 , also includes a control member, the slide seat includes a first slider 821, a tilting block 822, a second slider 823 and a first spring 824, the first slider 821 is slidably connected to the first slide groove 811, the tilting block 822 is fixedly arranged on the first slider 821, and is located on the side of the fixed block 81 close to the bending section, an inclined groove 8221 is opened on the tilting block 822 along the inclined direction, the second slider 823 is slidably connected to the inclined groove 8221, the first spring 824 is located in the inclined groove 8221, the two ends of the first spring 824 are respectively abutted against the top wall of the inclined groove 8221 and the top surface of the second slide groove, and the first spring 824 is always in a compressed state.

[0046] Reference Figure 10-12A second slide groove is provided on the side surface of the fixed block 81 facing the inclined block 822. The second slide groove includes a transverse portion 812 parallel to the length direction of the first slide groove 811 and an inclined portion 813 parallel to the direction of the inclined groove 8221. The transverse portion 812 is located above the inclined portion 813. One end of the second slider 823 close to the fixed block 81 is slidably connected in the second slide groove. One end of the second slider 823 away from the second slide groove extends out of the inclined groove 8221 and is fixed on the stretching block 84.

[0047] Reference Figure 10-12 The control member is used to drive the second slider 823 to slide in the inclined groove 8221. When the second slider 823 is located at the bottom end of the inclined portion 813, the preliminary bending assembly 6 operates, and the stretching block 84 abuts against the fixed column 62 to limit the copper wire; when the second slider 823 moves toward the side of the transverse portion 812, the pin spacing assembly 7 operates, and the stretching block 84 is located between the two pins of the bending section; when the second slider 823 slides in the transverse portion 812, the stretching block 84 stretches the end of the bending section and cuts the material.

[0048] Reference Figure 10-12 The control member includes a second spring 85 and a third slider 86 , and the third slider 86 is slidably connected to the first moving seat 52 along a sliding direction parallel to the sliding direction of the first slider 821 .

[0049] Reference Figure 10-12 The third slider 86 is located between the stretching block 84 and the tilting block 822. One end of the third slider 86 is located on the moving path of the movable block 74 and is provided with a first inclined surface 861. The other end of the third slider 86 is arranged close to the second slider 823 and is provided with a second inclined surface 862 matching the second slider 823. When the second clamping cylinder 54 is in the operation stage of the preliminary bending assembly 6, the movable block 74 is away from the third slider 86. The second spring 85 is used to drive the third slider 86 to move toward the side away from the second slider 823, so that the third slider 86 does not contact the second slider 823.

[0050] Reference Figure 10-12 When the pin spacing assembly 7 drives the two pins of the bending section to separate to a fixed distance, the movable block 74 abuts against the first inclined surface 861, and the second inclined surface 862 of the third slider 86 abuts against the second slider 823, driving the second slider 823 to move to the horizontal portion 812.

[0051] Reference Figure 10-12 When the preliminary bending assembly 6 is in operation, the stretching block 84 moves down to abut against the fixed column 62, and can press the copper wire that has escaped from the first gap 64 back into the first gap 64. At the same time, the stretching block 84 can also play a certain role in limiting the copper wire during the bending of the copper wire by the bending plate 63. The stretching block 84 will not affect the bending section during the process of the bending section standing up.

[0052] Reference Figure 10-12 When the pin spacing assembly 7 is running, the second clamping cylinder 54 drives one of the pins to move, so that the bending section automatically bypasses the fixed column 62 and the stretching plate during the erection process. Then, before the movable block 74 stops running, the movable block 74 acts on the first inclined surface 861 to drive the third slider 86 to move toward the second slider 823. Finally, the third slider 86 abuts against the bottom of the second slider 823, and the second slider 823 enters the transverse portion 812. At this time, the first cylinder 83 drives the first slider 821 to move outward, and the second slider 823 follows the first inclined block 822 and the first slider 821 to move outward together in the transverse portion 812, finally realizing the stretching of the end of the bending portion by the stretching block 84 and the blanking of the bending portion.

[0053] Of course, the above are only typical examples of the present application. In addition, the present application may have many other specific implementation methods. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present application.
