Description

Technical Field

[0001] This utility model relates to the field of riveting molds, specifically to a double-riveting mold. Background Technology

[0002] Riveting is a method of connecting a joint to other objects by using axial force to thicken the rivet shank inside the rivet hole and form a rivet head. Riveting dies are key process equipment for achieving high-quality riveting. They typically consist of an upper die and a lower die, which, driven by a drive mechanism, directly act on the riveting point to perform the riveting.

Detailed Implementation

[0021] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, illustrating only the basic aspects of the present utility model, and therefore only shows the components relevant to the present utility model. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] Please refer to Figure 2 and Figure 3 This utility model provides a double rivet mold 100, including a housing 10 and a driving component 20. Two rotating blocks 11 are rotatably connected to the housing 10 and are arranged opposite to each other. An upper mold 12 is provided on the rotating block 11, and a lower mold 13 is provided on the housing 10. The lower mold 13 is provided with two lower mold cores 14 that correspond to the two upper molds 12 respectively. A tension spring 15 corresponding to the rotating block 11 is connected to the housing 10, and the tension spring 15 is connected to the corresponding rotating block 11.

[0023] The output end of the drive component 20 is connected to a push block 21, which is located between two rotating blocks 11. The drive component 20 drives the push block 21 to rotate the two rotating blocks 11, so that both upper molds 12 move to cooperate with the corresponding lower mold cores 14 to rivet the photovoltaic product 200. Specifically, in this embodiment, the drive component 20 is a hydraulic cylinder, which is fixedly connected to the housing 10.

[0024] By setting up the push block 21 and the two rotating blocks 11, when riveting the photovoltaic product 200 and the connector 201, the drive component 20 drives the push block 21 to drive the two rotating blocks 11 to rotate, thereby driving the two upper molds 12 to simultaneously cooperate with the corresponding lower mold cores 14 to rivet, thus realizing the simultaneous riveting of the two riveting points and improving the riveting efficiency. At this time, the tension spring 15 is stretched.

[0025] After riveting is completed, the drive component 20 drives the push block 21 to move away from the two rotating blocks 11. The tension spring 15 resets and drives the two rotating blocks 11 to reset, thereby causing the two upper molds 12 to move away from each other.

[0026] For details, please refer to Figure 6 The lower mold 13 is provided with a disc spring 131, which is located between the two lower mold cores 14, and both lower mold cores 14 are pressed on the disc spring 131. After riveting is completed, the two upper molds 12 are respectively separated from the corresponding lower mold cores 14, and the disc spring 131 is reset, so that the lower mold cores 14 are separated from the connector 201 and the photovoltaic product 200, realizing material removal.

[0027] Please refer to Figure 3 and Figure 4 The rotating block 11 is provided with a roller 111. The pushing block 21 is provided with a guide surface 211 corresponding to the roller 111. The guide surface 211 is inclined. The end of the guide surface 211 closer to the lower mold 13 is closer to the central axis of the two lower mold cores 14 forming a straight line than the end of the guide surface 211 farther away from the lower mold 13.

[0028] The rollers 111 transform the contact between the rotating block 11 and the pushing block 21 into a rolling contact, reducing friction and wear on both blocks. This also facilitates the pushing block 21's rotation of the rotating block 11, improving the smoothness of their movement. Furthermore, the guide surface 211 further facilitates the pushing block 21's insertion between the two rotating blocks 11, pushing them away from each other and consequently bringing the two upper molds 12 closer together.

[0029] Please refer to Figure 4 The rotating block 11 includes a first block 112 rotatably connected to the housing 10 and a second block 113 rotatably connected to the first block 112. The second block 113 is connected to the upper mold 12. Specifically, the rotation center of the rotating block 11 is located at the middle of the first block 112.

[0030] Please refer to Figure 5 The housing 10 is provided with a guide block 16, and the guide block 16 is provided with a guide hole 161 corresponding to the rotating block 11. The second block 113 of the rotating block 11 passes through the guide hole 161. The rotation of the rotating block 11 is guided and limited by the setting of the guide hole 161, so that the upper mold 12 can move with the rotation of the rotating block 11 to cooperate with the corresponding lower mold core 14.
