Detailed Description of the Preferred Embodiment

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of 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. Embodiment

[0021] Such as Figure 1 、 Figure 2 and Figure 3As shown in the figure, a blanking mechanism of a stamping die proposed by an embodiment of the present utility model includes a bottom plate 1. A support rod 2 is fixedly connected to the upper surface of the bottom plate 1, and a die holder 4 is fixed to the upper end of the support rod 2. The die holder 4 includes a lower die body 401 fixedly connected to the upper end of the support rod 2. An array of stamping grooves 402 is formed in the lower die body 401. Circular holes penetrating downward are formed in the lower die body 401 at the positions of the stamping grooves 402. A ejector rod 404 is slidably connected to the circular holes of the lower die body 401. An ejecting block 403 is fixedly connected to the upper end of the ejector rod 404. The ejecting block 403 is adapted to the inside of the stamping groove 402. A roller 408 is installed at the lower end of the ejector rod 404. A round rod is rotatably connected to the center of the upper surface of the bottom plate 1, and a turntable 3 is fixed to the upper end of the round rod. An array of wedge blocks 8 is fixedly connected to the turntable 3. The wedge blocks 8 are distributed on one side corresponding to the rollers 408.

[0022] It should be noted that the bottom plate 1 and the support rod 2 are provided for supporting the die holder 4. The die holder 4 is used for stamping and forming stamped parts. By forming stamping grooves 402 in the lower die body 401, the stamped parts are stamped at the positions of the stamping grooves 402. By forming circular holes in the lower die body 401, the circular holes penetrate through the stamping grooves 402 to the lower part of the lower die body 401, so that the ejector rod 404 can stretch up and down. When the ejector rod 404 moves, it drives the ejecting block 403 to move, realizing the blanking and jacking of the stamped parts and discharging the stamped parts. By installing a roller 408 at the lower end of the ejector rod 404, the lifting control of the ejector rod 404 is realized. By rotatably connecting a round rod to the bottom plate 1, the turntable 3 can be driven to rotate when the round rod rotates. By fixedly connecting an array of wedge blocks 8 to the turntable 3, when the wedge blocks 8 move, their wedge surfaces contact the rollers 408, and then drive the rollers 408 and the ejector rod 404 to move, realizing the movement control of the ejecting block 403, and then controlling the jacking of the stamped parts. This method can meet the jacking of multiple stamped parts at one time, with high efficiency.

[0023] As Figure 2 shown, in some embodiments, a circular cavity 405 is coaxially arranged at the circular holes of the lower die body 401. A circular plate 407 fixed on the ejector rod 404 is adapted to the circular cavity 405 of the lower die body 401. A spring 406 is arranged between the upper surface of the circular plate 407 and the lower die body 401.

[0024] It should be noted that by forming a circular cavity 405 in the lower die body 401, the circular cavity 405 is provided for accommodating the circular plate 407 and the spring 406. When the ejector rod 404 slides upward, the spring 406 is compressed. When the wedge block 8 leaves the roller 408, the ejector rod 404 and the ejecting block 403 can be reset under the action of the spring 406, so that the ejecting block 403 closes to the bottom of the stamping groove 402, and then the stamping of the stamped parts is carried out.

[0025] AsFigure 1 and Figure 4 As shown in Figure 4 , in some embodiments, a rotation driving mechanism 9 for controlling the rotation of the round rod and the turntable 3 is installed on the bottom plate 1. The rotation driving mechanism 9 includes a motor 904 installed on the bottom plate 1, and a driven wheel 901 is fixedly connected to the round rod. A driving wheel 903 is arranged on the output shaft of the motor 904, and a synchronous belt 902 is arranged between the driven wheel 901 and the driving wheel 903.

[0026] It should be noted that the setting of the rotation driving mechanism 9 can realize the rotation control of the round rod and the turntable 3, and then control the positioning and jacking of the workpiece. The motor 904 can control the rotation of the driving wheel 903, and then realize the rotation drive of the round rod through the relationship of the synchronous belt 902 and the driven wheel 901, and then control the rotation of the turntable 3.

[0027] Such as Figure 1 , Figure 2 and Figure 3 As shown in Figure 3 , in some embodiments, a clamping mechanism 6 is installed at the center of the upper surface of the lower die body 401. The clamping mechanism 6 includes a disc 605 rotatably connected to the center of the lower die body 401, and a limiting track 601 fixedly arranged on the lower die body 401 in an array. A telescopic plate 603 is slidably connected to each of the limiting tracks 601. A movable clamping block 602 is fixed at one end of the telescopic plate 603, and a support arm 604 is rotatably connected between the disc 605 and each telescopic plate 603.

[0028] It should be noted that the setting of the clamping mechanism 6 can realize the automatic clamping of the workpiece, which is convenient for stamping the workpiece and ensures the stamping quality. When loading, the workpiece is placed at the stamping groove 402 of the lower die body 401. The rotation driving mechanism 9 drives the turntable 3 to rotate, so that the wedge block 8 leaves the roller 408. At this time, the jacking block 403 returns under the action of the spring 406 and closes to the bottom of the stamping groove 402. At the same time, the rotating rod 7 drives the disc 605 in the clamping mechanism 6 to rotate, and the telescopic plate 603 is supported through the support arm 604, so that the telescopic plate 603 slides on the limiting track 601, drives the movable clamping block 602 to move, and cooperates with the static clamping block 5 to clamp the workpiece. Then, the workpiece is stamped. When it is necessary to jack up and unload the stamped part, the turntable 3 is rotated in the reverse direction through the rotation driving mechanism 9, so that the wedge block 8 approaches the roller 408. At this time, the disc 605 rotates in the reverse direction, and then the telescopic plate 603 is pulled through the relationship of the support arm 604, so that the movable clamping block 602 leaves the stamped part and cancels the positioning function of the stamped part. At the same time, the wedge surface of the wedge block 8 contacts the roller 408, driving the ejector rod 404 and the jacking block 403 to move upward, realizing the elastic ejection and jacking of the stamped part. Therefore, this method can realize the loosening and elastic ejection of the workpiece synchronously, and can also perform the loading and clamping of the stamped part synchronously, without using other positioning tools, with good effect and strong functionality.

[0029] As Figure 1 , Figure 2 and Figure 3 shown, in some embodiments, a rotating rod 7 is fixedly connected between the center of the upper surface of the turntable 3 and the disc 605, and a relief hole is formed in the lower die body 401 corresponding to the rotating rod 7.

[0030] It should be noted that the setting of the rotating rod 7 can realize the rotation control of the disc 605. When the turntable 3 rotates, the disc 605 can be driven to rotate synchronously through the relationship of the rotating rod 7.

[0031] As Figure 1 and Figure 3 shown, in some embodiments, static clamping blocks 5 are fixedly connected to one side of the stamping groove 402 of the lower die body 401, and the dynamic clamping block 602 and the static clamping block 5 cooperate to clamp and fix the workpiece.

[0032] It should be noted that when the telescopic plate 603 moves, the dynamic clamping block 602 moves accordingly, and then the workpiece can be clamped in cooperation with the static clamping block 5.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
