Specific embodiments

[0023] The following specific embodiments illustrate the implementation manners of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] With reference to Figures 1 - 5 , the present utility model provides a rotary stamping die for hardware parts, including a mold carrier table 1 and a first bracket 8 and a second bracket 81 arranged above the mold carrier table 1. The first bracket 8 and the second bracket 81 can be installed on the installation surface of the stamping environment by bolts. A rotating disk 2 is arranged on the mold carrier table 1, and a first rotating device 3 for driving the rotating disk 2 to rotate is arranged at the bottom of the mold carrier table 1. The first rotating device 3 can adopt a rotating motor, and the output end of the rotating motor can pass through the mold carrier table 1 and be fixedly connected to the rotating disk 2. A plurality of bases 4 are fixedly connected to the upper surface of the rotating disk 2, and a lower mold 5 is arranged on the top of the base 4. The base 4 can be used to raise the height of the lower mold 5 so that the lower mold 5 can be adjusted in angle. A stamping mechanism 12 is arranged on the second bracket 81.

[0025] The periphery of the mold carrier 1 is fixedly connected with fixing ears 15. The fixing ears 15 can be used to install the mold carrier 1 in cooperation with bolts. A rolling groove 13 is provided at the bottom of the rotating disc 2. A rolling body 14 is movably connected in the rolling groove 13, and the rolling body 14 is also movably connected to the upper surface of the mold carrier 1. In this application, a groove body adapted to the rolling groove 13 is also provided on the upper surface of the mold carrier 1. In this way, when the rotating device 1 drives the rotating disc 2 to rotate, the rolling body 14 can slide in the groove body and the rolling groove 13 to increase the balance and force-bearing support of the rotating disc 2.

[0026] The stamping mechanism 12 includes a hydraulic device 121 fixedly connected to the second bracket 81 and an upper mold 122 fixedly connected to the output end of the hydraulic device 121. The upper mold 122 is used for stamping the raw materials of the hardware parts on the lower mold 5. The hydraulic device 121 can adopt a hydraulic press, which can give the upper mold 122 the lifting power.

[0027] Specifically, an external controller is used to control the intermittent drive output of the rotating device 1. In this way, the rotating disc 2 can drive a plurality of lower molds 5 to pass sequentially below the upper mold 122, and the hydraulic device 121 gives the upper mold 122 the lifting power to act, so that it is convenient to stamp the hardware parts on the lower mold 5.

[0028] A torsion spring rotating assembly 7 is provided on the base 4 and the lower mold 5. A pull rod 11 is fixedly connected to the lower mold 5. A blanking drive structure 10 is provided on the first bracket 8. A blanking lever 9 is provided on the blanking drive structure 10, and the blanking lever 9 is in movable contact with the pull rod 11.

[0029] The torsion spring rotating assembly 7 includes an outer rotating seat 71 fixedly connected to the base 4, a torsion spring rotating shaft 72 arranged inside the outer rotating seat 71, and an inner rotating seat 73 arranged on the torsion spring rotating shaft 72. The inner rotating seat 73 is rotatably connected to the outer rotating seat 71 through the torsion spring rotating shaft 72. The inner rotating seat 73 is fixedly connected to the lower mold 5. The torsion spring rotating shaft 72 is a structure composed of a torsion spring and a rotating shaft. In this way, the inner rotating seat 73 can be rotatably arranged on the outer rotating seat 71 with resetability.

[0030] A shock pad 51 is fixedly connected to the bottom of the lower mold 5. When the lower mold 5 is rotatably arranged on the base 4 through the torsion spring rotating assembly 7, that is, when the lower mold 5 discharges the finished products of the hardware parts, when the lower mold 5 is reset under the elastic force of the torsion spring, the shock pad 51 can reduce the impact force between the lower mold 5 and the base 4.

[0031] The lower die 5 is provided with a feeding limit component 6. The feeding limit component 6 includes a fixed disk 61 fixedly connected to the periphery of the top of the lower die 5 and three limit posts 62 fixedly connected to the upper surface of the fixed disk 61. When the upper die 122 performs a stamping operation on the lower die 5, the upper die 122 does not contact the fixed disk 61 and the limit posts 62. The three-point arranged limit posts 62 can facilitate the positioning of the raw materials of the hardware parts to ensure the centering of the stamping of the raw materials of the hardware parts.

[0032] The blanking driving structure 10 includes a suspension seat 101 fixedly connected to the lower side inside the first bracket 8, a rotating frame 102 rotatably connected to the suspension seat 101, and a second rotating device 103 fixedly connected to the suspension seat 101 and used to drive the rotating frame 102 to rotate. The blanking lever 9 is movably connected to the rotating frame 102. The output end of the second rotating device 103 passes through the suspension seat 101 and is fixedly connected to the rotating frame 102. The second rotating device 103 in this application can adopt a forward and reverse rotating motor.

[0033] It should be noted that when stamping the hardware parts in this application, the operation control of each electrical device can be controlled by an existing controller, and the control signal obtained by the controller can be provided by monitoring the position of the hardware parts on the lower die 5 through an existing photoelectric module. For example, when the raw material of the hardware parts on the lower die 5 moves below the upper die 122, the photoelectric module can obtain the information of the processing position of the raw material of the hardware parts, so that the raw material of the hardware parts can be stamped; when the hardware parts product on the lower die 5 moves to one side of the blanking lever 9, the blanking driving structure 10 can provide a blanking driving force for the hardware parts product on the lower die 5.

[0034] Specifically, when the hardware parts are formed on the lower die 5 and at the same time the lower die 5 rotates to one side of the blanking lever 9, the second rotating device 103 can drive the rotating frame 102 to rotate until the blanking lever 9 on the rotating frame 102 is slidably connected to the pull rod 11. In this way, the pull rod 11 can give a certain thrust to the lower die 5, and the lower die 5 can rotate on the base 4 through the torsion spring rotating assembly 7 for the purpose of changing the inclination angle of the lower die 5, which can facilitate the blanking of the hardware parts product on the lower die 5. When the blanking lever 9 rotates in the reverse direction later, the elastic force of the torsion spring structure can make the lower die 5 reset to the base 4.
