Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present invention are only for the convenience of clear narration, rather than used to limit the scope of implementation of the present invention. The change or adjustment of their relative relationship, without substantial change in the technical content, should also be regarded as the scope of implementation of the present invention.

[0024] Referring to Figures 1-4 , a forming device for a vehicle flower-shaped bolt, includes a first workbench 1, a second workbench and a material receiving frame 2. An extrusion assembly is arranged on the second workbench. A bracket 7 is rotatably arranged on the first workbench 1. A plurality of servo motors are fixedly installed on the bracket 7. The driving end of each servo motor is fixedly connected with a mounting block 6 with a T-shaped cross-section. A groove is opened on one side of the mounting block 6. A lower die 3 is arranged on one side of the groove. A fixed block 16 for connecting the groove is fixedly connected to one side of each lower die 3. The cross-section of the fixed block 16 is concave-shaped. A limiting assembly is arranged in each groove. The limiting assembly includes two rotating plates 13 rotatably arranged on the inner wall of the groove. A clamping block 17 is fixedly connected to one side of each rotating plate 13. Card slots are opened on both side surfaces of each fixed block 16.

[0025] A sliding rod 11 is slidably connected to each mounting block 6. The end of the sliding rod 11 extending into the groove is fixedly connected with an extrusion rod 15. The two ends of the extrusion rod 15 are respectively in contact with the surfaces of the two rotating plates 13. Each rotating plate 13 is connected to the inner wall of the groove through a torsion spring 12. When pulling the sliding rod 11, during the relative sliding of the sliding rod 11 and the mounting block 6, the surfaces at both ends of the extrusion rod 15 will respectively abut against the surfaces of the two rotating plates 13 and move. Each rotating plate 13 rotates relative to the inner wall of the groove at the same time, and the torsion spring 12 deforms.

[0026] Each sliding rod 11 is connected to the mounting block 6 through the threaded rod 10. A threaded groove for connecting the threaded rod 10 is provided on the mounting block 6. One end of the threaded rod 10 penetrates through the sliding rod 11 and is threadedly connected to the threaded groove, which can prevent the sliding rod 11 and the extrusion rod 15 from moving relative to the mounting block 6 randomly. A plurality of positioning rods 14 are fixedly connected to the inner wall of one side of each groove. A plurality of round holes for connecting the positioning rods 14 are provided on each fixing block 16. The fixing block 16 is inserted into the groove. At this time, the respective round holes are sleeved on the outer sides of the corresponding positioning rods 14. The positioning rods 14 have a certain positioning effect on the installation position of the fixing block 16.

[0027] The extrusion assembly includes a hydraulic cylinder 4 fixedly installed on the second workbench. The driving end of the hydraulic cylinder 4 is clamped with an upper die 5. When the hydraulic cylinder 4 drives the upper die 5 to move downward, the material in the extrusion groove of the lower die 3 can be extruded and formed, so as to facilitate the forming process of the flower-shaped bolt. The second workbench is connected to an arc-shaped block 19 through two first springs 9. An arc-shaped surface 18 is provided on the arc-shaped block 19. The bracket 7 rotates under the driving action of the motor. When a lower die 3 rotates to directly below the upper die 5, the bottom surface of the lower die 3 will squeeze the arc-shaped surface 18 of the arc-shaped block 19, causing the arc-shaped block 19 and the second workbench to slide relative to each other. Since one end of each first spring 9 is fixedly connected to the second workbench and the other end is fixedly connected to the surface of the arc-shaped block 19, under the elastic force of the first spring 9, the arc-shaped surface 18 of the arc-shaped block 19 will fit with the bottom surface of the lower die 3. The arc-shaped block 19 has a certain supporting effect on the lower die 3.

[0028] Two inclined plates 8 are fixedly connected inside the material receiving frame 2. The two inclined plates 8 are arranged in a staggered manner. The two inclined plates 8 are arranged in a downward inclined and staggered manner. When the flower-shaped bolts fall into the interior of the material receiving frame 2, the flower-shaped bolts will slide along the surfaces of the two inclined plates 8 respectively until they fall to the bottom of the material receiving frame 2, which has a certain buffering effect on the flower-shaped bolts and avoids excessive impact force when the flower-shaped bolts fall.

[0029] In the present utility model, during use, first insert the fixing block 16 into the groove. At this time, each circular hole is respectively sleeved on the outside of the corresponding positioning rod 14, and the two rotating plates 13 are located in the notch formed by the surface of the concave-shaped fixing block 16. Then, pull the sliding rod 11. During the relative sliding of the sliding rod 11 and the mounting block 6, the surfaces at both ends of the extrusion rod 15 will respectively abut against the surfaces of the two rotating plates 13 and move. Each rotating plate 13 will simultaneously rotate relative to the inner wall of the groove. Since one end of the torsion spring 12 is fixedly connected to the rotating plate 13 and the other end is fixedly connected to the inner wall of the groove, the torsion spring 12 is deformed. After each locking block 17 rotates together with the rotating plate 13, it will be engaged with the corresponding card slot on the fixing block 16. Finally, insert one end of the threaded rod 10 through the sliding rod 11 and thread it with the threaded groove, which can prevent the sliding rod 11 and the extrusion rod 15 from moving randomly, thereby preventing the locking block 17 from disengaging from the card slot. Then, the lower die 3 can be firmly connected to the mounting block 6. Similarly, when the lower die 3 is damaged due to long-term use, or there is a lot of material residue on the inner wall of the extrusion groove of the lower die 3, it is convenient to quickly remove the lower die 3 for cleaning or replacement, which is beneficial to the use of the forming device.

[0030] In the present utility model, unless otherwise clearly defined and limited, terms such as "installation", "connection", "connection", "fixation" and other terms shall be understood in a broad sense.

[0031] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
