[0002] In the intelligent plug assembly equipment, it is a kind of equipment that can cut the wire coil into set length, strip the wire at both ends, and finally tin the wire before assembling the terminal.

[0003] In order to ensure that each core wire is independent of each other, the core wires at the end of the wire need to be separated by a certain distance, so that the two core wires can be aligned with the two feed holes of the twisted copper wires when twisting the copper wires later, and it can also prevent the wires from sticking together after being dipped in tin liquid. Therefore, the core wires of the wire need to be shaped to ensure that the spacing between the core wires of the wire is equal.

[0004] In the existing wire core shaping structure, a shaping mold is generally set, and the two wire cores are pre-bent to a certain angle manually, and then placed in the mold for shaping for a few seconds, and then the wire cores are taken out of the mold. This mold structure requires manual pre-bending of the wire, which is labor-intensive and has low shaping efficiency. Utility Model Content

[0030] The utility model is further described below in conjunction with the accompanying drawings.

[0031] like Figures 1 to 7 As shown, the long core wire shaping structure described in the utility model includes a first shaping cylinder B1, a shaping fixing seat B3 and a shaping support seat B6; a lower shaping cavity B603 is arranged on the surface of the shaping support seat B6; a shaping outer shell B4 is fixed on the shaping fixing seat B3; the cross section of the shaping outer shell B4 is in a "U" shape;

[0032] The first shaping cylinder B1 is fixed on the shaping fixed seat B3; the shaping upper slide seat B8 is slidably connected inside the shaping outer shell B4; a shaping cone B801 is provided at one end of the shaping upper slide seat B8 close to the shaping support seat B6; the diameter of the shaping cone B801 gradually decreases as it approaches the shaping support seat B6; the two ends of the first shaping cylinder B1 are respectively fixed on the shaping upper slide seat B8 and the shaping fixed seat B3;

[0033] After the wire enters above the shaping support seat B6, the lifting support cylinder B7 connected to the shaping support seat B6 lifts the wire to the set height until the surface of the shaping support seat B6 fits on the surface of the shaping outer shell B4, so that the shaping end of the wire is inserted into the inner cavity of the shaping outer shell B4; the end of the wire is pressed against the positioning front surface B402 on the shaping outer shell B4; the lower shaping mold cavity B603 is used as a cavity to avoid the shaping cone B801; it is used for the shaping cone B801 to be inserted during shaping;

[0034] The first shaping cylinder B1 drives the shaping upper slide B8 to slide downward; the conical shaping cone B801 moves from top to bottom, the cone passes through the two wire cores, and gradually expands the wire core outward through the conical surface of the shaping cone B801, so that the distance between the two wire cores gradually increases, until the outer side of the wire core fits on the inner side wall of the upper shaping cavity B401 of the shaping outer shell B4; the inner side wall of the shaping outer shell B4 cooperates with the surface of the shaping cone B801 to form a cavity to shape the wire core;

[0035] In this structure, two forming cavities are formed by the lifting shaping cone B801 structure in cooperation with the inner cavity of the shaping outer shell B4 to automatically shape the two wire cores, thereby greatly improving the wire core shaping efficiency and reducing labor intensity.

[0036] As a preferred embodiment of the utility model, both sides of the lower shaping mold cavity B603 are slidably connected with support sliders B602; the top surface of the support slider B602 and the top surface of the shaping support seat B6 are arranged on the same plane; a spring is connected between the support slider B602 and the inner side wall of the lower shaping mold cavity B603; a slider guide strip B603a is arranged in the lower shaping mold cavity B603; the slider guide strip B603a is used to form a sliding connection for the groove opened on the side surface of the support slider B602;

[0037] Under the action of the spring, the two supporting sliders B602 are brought close to each other, and the gap between the two supporting sliders B602 is facing the cone top of the shaping cone B801. When the shaping cone B801 is not inserted into the lower shaping cavity B603, the two supporting sliders B602 are brought close to each other and support the two wire cores. As the core wire is stretched open by the shaping cone B801, the two supporting sliders B602 are also pushed open. In this way, the wire core is always supported on the supporting sliders B602, preventing the wire core from deforming toward the lower shaping cavity B603, thereby improving the shaping quality of the wire core.

[0038] As a preferred embodiment of the utility model, a wire positioning seat B5 is slidably connected to the shaping fixed seat B3; a shaping positioning cylinder B2 is connected between the shaping fixed seat B3 and the wire positioning seat B5; a wire pressing module is arranged at the bottom end of the wire positioning seat B5; the wire pressing module is composed of two wire positioning plates B501 fixed on the wire positioning seat B5; a positioning chamfered surface B501a ​​is arranged between the bottom end surface of the wire positioning plate B501 and the inner surface of the wire positioning plate B501; a shaping positioning groove B601 matching the wire positioning plate B501 is arranged on the top surface of the shaping support seat B6;

[0039] The shaping positioning groove B601 is used to avoid the wire positioning plate B501 when it descends. After the wire is lifted into place by the shaping support seat B6, the shaping positioning cylinder B2 drives the wire positioning seat B5 to move downward, and the wire is clamped between the two wire positioning plates B501 of the wire pressing module. Then, the wire is positioned and guided by the positioning chamfered surfaces B501a ​​on both sides to center the wire. Finally, the wire positioning seat B5 presses the wire against the surface of the shaping support seat B6 to prevent the outer side of the shaping outer shell B4 from bending during wire shaping, thereby ensuring that the wire can remain straight after shaping.

[0040] As a preferred embodiment of the utility model, the number of the wire clamping modules is two; the number and positions of the shaping positioning grooves B601 are designed according to the number and positions of the wire positioning plates B501; the wire clamping modules are arranged along the length direction of the wire, which can form multi-position clamping and further reduce the risk of wire bending.

[0041] As a preferred embodiment of the present invention, the inner side wall of the shaping outer shell B4 is provided with a dovetail groove B401a; the shaping upper slide seat B8 is provided with a shaping upper guide rail B802 slidably connected to the dovetail groove B401a.
