Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The present invention provides a copper wire U-shaped bending machine, comprising: a lower fixed plate 5, two side panels 8 fixedly connected to the top of the lower fixed plate 5, the two side panels 8 being arranged left and right, and an upper fixed plate 3 being fixedly installed on the top of the two side panels 8, a cylinder 1 fixedly installed on the top of the upper fixed plate 3, a support plate 7 fixedly installed at the bottom extension end of the cylinder 1, the support plate 7 being located at the bottom of the upper fixed plate 3, and an upper die 11 fixedly installed at the bottom of the support plate 7, a lower die 12 being provided at the bottom of the upper die 11, the lower die 12 being installed on the top of the lower fixed plate 5, a solenoid valve 10 being installed on the front side of the cylinder 1, and an electrical control box 4 being installed on the outer wall of the left side panel 8.

[0034] Specifically, the copper wire to be bent is first placed on the surface of the lower die 12, and the cylinder 1 is driven by the electrical control box 4 and the solenoid valve 10. The cylinder 1 moves the support plate 7 down, and the support plate 7 moves the bottom upper die 11 down. The bending operation of the copper wire is achieved by the pressing between the upper die 11 and the lower die 12. The bent part of the copper wire is set in an arc shape, which has good consistency. At the same time, bending the U-shaped jumper wire does not damage the surface coating, which greatly reduces the problem of copper wire overheating and short circuit due to coating damage.

[0035] The electrical control box 4 works in conjunction with the solenoid valve 10 to control the direction of the cylinder 1's movement, thereby driving the support plate 7 to move up and down.

[0036] In this embodiment, as Figures 1-2 As shown; two bearing rods 2 are fixedly connected to the top of the support plate 7, and two bearing sleeves 6 are fixedly installed through the upper fixed plate 3. The top ends of the two bearing rods 2 pass through the two bearing sleeves 6 respectively and extend to the top of the bearing sleeves 6, and the bearing rods 2 and bearing sleeves 6 are movably connected.

[0037] Specifically, when the support plate 7 moves up and down, it will drive the two bearing rods 2 to move synchronously. The two bearing rods 2 slide up and down inside the two bearing sleeves 6 respectively, thereby limiting the up and down movement trajectory of the support plate 7, improving the stability of the up and down movement of the support plate 7, and preventing shaking.

[0038] In this embodiment, as Figure 1 As shown: the bearing rod 2 and the bearing sleeve 6 are both set vertically.

[0039] Specifically, the above settings can effectively prevent misalignment when the bearing rod 2 and bearing sleeve 6 slide.

[0040] In this embodiment, as Figures 1-3 As shown; limit blocks 21 are fixedly connected to the top of both bearing rods 2.

[0041] Specifically, by using the limit block 21, it can abut against the top of the bearing sleeve 6 when the bearing rod 2 moves downward in a straight line, thereby limiting the downward movement of the bearing rod 2 and even components such as the support plate 7.

[0042] In this embodiment, as Figures 1-3 As shown; the limiting block 21 is circular, and the outer diameter of the limiting block 21 is larger than the inner diameter of the bearing sleeve 6.

[0043] Specifically, the above settings can effectively prevent the bearing rod 2 from separating from the bearing sleeve 6.

[0044] In this embodiment, as Figure 4 As shown; a slide block 13 is fixedly installed at the bottom of the lower mold 12, and a slide rail 9 is fixedly installed at the top of the lower fixed plate 5. The slide block 13 is slidably connected to the top of the slide rail 9.

[0045] Specifically, the cooperation between the slide rail 9 and the slide block 13 enables the lower mold 12 to slide horizontally, facilitating subsequent mold changing operations.

[0046] In this embodiment, as Figure 4 As shown; both the slide rail 9 and the slide block 13 are provided in two sets. Both sets of slide blocks 13 are located at the bottom of the lower mold 12 and are arranged left and right. Both sets of slide rail 9 are located at the top of the lower fixed plate 5 and are arranged left and right.

[0047] Specifically, the two slide rails 9 and slide blocks 13, which are set on the left and right sides, facilitate mold changing and provide stable support.

[0048] In this embodiment, as Figure 2 As shown: the outer diameter of the lower fixing plate 5 is set to be larger than the outer diameter of the upper fixing plate 3.

[0049] Specifically, the above settings provide sufficient sliding space for the slide rail 9 and the slide block 13, facilitating mold changing operations.

[0050] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0051] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
