DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] like Figures 1 to 6 As shown, the utility model provides a busbar rivet nut mold, including: an upper mold 100, a lower mold 200, a nut mounting strip 400 and a fixing device 300. The upper mold 100 is arranged directly above the lower mold 200. The lower mold 200 is provided with a mounting groove for placing the nut mounting strip 400, and a plurality of receiving grooves 220 for placing the rivet nuts 500 are arranged at intervals at the bottom of the mounting groove. A plurality of rivet grooves are arranged on the nut mounting strip 400, and a plurality of mounting holes for mounting nuts are arranged on the rivet groove, and the positions of the mounting holes correspond one-to-one to the receiving grooves 220. The bottom of the upper mold 100 is provided with pressure blocks 110 at intervals, and the positions of the pressure blocks 110 correspond one-to-one to the rivet grooves. The fixing device 300 is used to fix the busbar to the lower mold 200. During processing, the busbar is placed on the nut mounting strip 400, and the rivet nut 500 on the nut mounting strip 400 passes through the pre-opened hole on the busbar. After the upper mold 100 and the lower mold 200 are closed, the rivet nut 500 is riveted to the busbar.

[0026] In this embodiment, during the processing, first, the rivet nut 500 is installed in the mounting hole of the nut mounting strip 400. The lower end of the rivet nut 500 is smaller and passes through the mounting hole, and the upper end of the rivet nut 500 remains in the riveting groove. The nut mounting strip 400 equipped with the rivet nut 500 is installed on the mounting groove, and the lower half of the rivet nut 500 is just placed in the receiving groove 200. Then the busbar is placed on the nut mounting strip 400, so that the pre-processed hole on the busbar is aligned with the upper end of the rivet nut 500, and then installed, and then the busbar is fixed using the fixing device 300, and then the upper mold 100 is pressed downward, so that the pressure block 110 is pressed on the rivet nut 500, and the rivet nut 500 is riveted to the busbar. Then the upper mold 100 is raised, the fixing device 300 is loosened, the busbar and the nut mounting strip 400 are removed from the lower mold 200, and the nut mounting strip 400 is removed from the bottom of the busbar.

[0027] The nut mounting strip 400 includes a first mounting strip 410 and a second mounting strip 420, the rivet grooves include a first rivet groove 411 and a second rivet groove 421, and the mounting holes include a first mounting hole 412 and a second mounting hole 422. The first mounting strip 410 is provided with a plurality of first rivet grooves 411 at intervals, and the first rivet groove 411 is provided with a first mounting hole 412. The second mounting strip 420 is provided with a plurality of second rivet grooves 421 at intervals, and the second rivet groove 421 is provided with a second mounting hole 422. The second mounting strip 420 is also provided with a placement groove 423 on one side of the second rivet groove 421, and the depth of the placement groove 423 is deeper than that of the second rivet groove 421.

[0028] In this embodiment, sometimes the structure of the processed busbar is more complicated, and the riveting positions are not on the same horizontal plane, so the riveting cannot be completed in one time and needs to be divided into two or more times for riveting.

[0029] During the first riveting, the lower riveted portion on the busbar can be placed in the first rivet groove 411 of the first mounting bar 410, and the higher riveted portion can be placed in the ungrooved position on the first mounting bar 410, and then the upper mold 100 is driven down to complete the first riveting.

[0030] During the second riveting, the nut has been riveted at the lower riveted position and is placed in the placement groove 423. A through groove 424 is provided on one side of the placement groove 423 to facilitate the passage of the riveted nut. At the same time, the position of the placement groove 423 corresponds to the receiving groove 220, and the riveted nut can enter the receiving groove 220; the higher riveted position is placed in the second riveting groove 421, and then the upper mold 100 is driven down to complete the second riveting.

[0031] In the above embodiment, before the first riveting and the second riveting, the rivet nut 500 needs to be installed in advance in the first riveting groove 411 and the second riveting groove 421. There are six first riveting grooves 411 and six second riveting grooves 421.

[0032] In this embodiment, the pressing block 110 includes a first pressing block 111 and a second pressing block 112. The position of the first pressing block 111 corresponds to the first rivet groove 411, and the position of the second pressing block 112 corresponds to the second rivet groove 421. The first pressing block 111 cooperates with the first rivet groove 411, and the second pressing block 112 cooperates with the second rivet groove 421. In terms of thickness in the vertical direction, the first pressing block 111 is thicker than the second pressing block 112.

[0033] The lower mold 200 is provided with a cavity 210 below the accommodating groove 220. In this embodiment, the cavity 210 can be used to place the unprocessed part of the busbar.

[0034] The fixing device 300 is a horizontal quick clamp, which is symmetrically arranged on both sides of the lower mold 200. In this embodiment, the horizontal quick clamp can quickly clamp and release the busbar, thereby improving processing efficiency.

[0035] Guide grooves are provided on both sides of the top surface of the lower mold 200, and guide posts 120 adapted to the guide grooves are fixedly connected to both sides of the bottom of the upper mold 100. In this embodiment, the guide grooves and the guide posts 120 are movably matched, and the matching of the guide grooves and the guide posts 120 can improve the mold clamping accuracy.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
