In the following embodiments, it is mainly introduced by taking the example of being applicable to the configuration for processing tantalum capacitors. Other situations that require a disk-type cam powder pressing and forming mechanism can be referred to for implementation.

[0035] Please refer to Figure 1, in an embodiment of the disc cam powder pressing and forming mechanism of the present invention, the disc cam powder pressing and forming mechanism includes a mounting table 100, a rotating disc 200, a forming jig, a first forming member 400, two second forming members 500, a limit stop 600 and a driving assembly 700. Among them, the mounting table 100 is provided with a blanking hole; the rotating disc 200 is mounted on the mounting table 100, and a mounting groove 201 is opened at the center of the rotating disc 200; the forming jig 300 includes a mounting portion 310 and a forming portion 320 connected to the mounting portion 310, and the mounting portion 310 extends into the mounting groove 201; the forming portion 320 is provided with a blanking groove 301 penetrating the mounting portion 310 in the up and down direction, and the blanking groove 301 is communicated with the blanking hole; the top of the forming portion 320 is provided with a first positioning groove 321 and two second positioning grooves 322 located on both sides of the first positioning groove 321; the blanking groove 301 is communicated with the first positioning groove 321 and the two second positioning grooves 322; the first forming member 400 is movably mounted in the first positioning groove 321, and the first forming member 400 is rotationally matched with the rotating disc 200; the two second forming members 500 are movably respectively mounted in the two second positioning grooves 322, and the two second forming members 500 are rotationally matched with the rotating disc 200; the limit stop 600 is arranged above the blanking groove 301, and both ends of the limit stop 600 are located in the two second positioning grooves 322 respectively; the driving assembly 700 is connected to the rotating disc 200 and is used to drive the rotating disc 200 to rotate; wherein, when the driving assembly 700 drives the rotating disc 200, it can successively drive the first forming member 400 to move away from the limit stop 600 and the two second forming members 500 to move away from the limit stop 600, so that the finished product falls from the blanking groove 301 and the blanking hole.

[0036] Specifically, the shape of the first positioning groove 321 is adapted to the shape of the first forming member 400, so that the first forming member 400 is movably mounted in the first positioning groove 321; the shapes of the two second positioning grooves 322 are respectively adapted to the two second forming members 500, so that the two second forming members 500 are respectively mounted in the two second positioning grooves 322. In this embodiment, the driving assembly 700 is a motor. A gear can be provided on the output shaft of the motor and a gear can be provided on the rotating disc 200, so that the rotating disc 200 meshes with the motor gear, which is not limited herein. In other embodiments, the rotating disc 200 can also be manually driven to rotate.

[0037] For the process of pressing powder by the disk cam powder pressing and forming mechanism, first make the first forming member 400 abut against the limit stop 600, then place the powder on the first forming member 400, and then drive the driving assembly 700 to drive the rotating disk 200 to rotate, so that the two second forming members 500 extrude the powder in the direction close to the installation groove 201. For the upper part of the powder, the upper part of the powder can be manually pressed by a flat plate, so as to complete the pressing and forming of the powder.

[0038] For the process of discharging materials by the disk cam powder pressing and forming mechanism, since the end of the first forming member 400 has been abutting against the limit stop 600, first drive the driving assembly 700 to drive the rotating disk 200 to rotate, then the rotating disk 200 drives the first forming member 400 to move away from the limit stop 600, and then the rotating disk 200 drives the two second forming members 500 to move away from the limit stop 600, so that the finished product falls from the blanking groove 301 and the blanking hole. It should be noted that after the first forming member 400 moves away from the limit stop 600, the two second forming members 500 are still extruding the finished product. When the driving disk is further driven, the two second forming members 500 move away from the limit stop 600, and the finished product falls from the blanking groove 301 and the blanking hole. That is to say, when discharging materials, the first forming member 400 and the two second forming members 500 have a time difference in moving away from the limit stop 600, so as to reduce the surface friction damage of the finished product.

[0039] It can be understood that in order to better protect the product, the blanking hole and the blanking groove 301 are arranged on the same straight line, and a blowing device can also be arranged at the bottom of the installation table 100, and the blowing device is aligned with the blanking hole, so as to avoid the finished product being impacted when falling. It should be noted that the processing process of the product is to extrude the powder into a finished product.

[0040] The technical solution of the present invention is provided with a mounting table 100, a rotating disk 200, a molding jig 300, a first molding part 400, two second molding parts 500, a limit stopper 600 and a driving assembly 700, wherein the mounting table 100 is provided with a blanking hole, the rotating disk 200 is installed on the mounting table 100, a mounting groove 201 is provided at the center of the rotating disk 200, the molding jig 300 includes a mounting portion 310 and a molding portion 320 connected to the mounting portion 310, and the mounting The part 310 extends into the installation groove 201, the forming part 320 is provided with a blanking groove 301 penetrating the installation part 310 in the up-down direction, the blanking groove 301 is communicated with the blanking hole, the top of the forming part 320 is provided with a first positioning groove 321, and two second positioning grooves 322 located on both sides of the first positioning groove 321, the blanking groove 301 is communicated with the first positioning groove 321 and the two second positioning grooves 322, the first forming part 400 is movably installed in the first positioning groove 321, and The first forming piece 400 is rotatably matched with the rotating disk 200, and the two second forming pieces 500 are movably installed in the two second positioning grooves 322 respectively, and the two second forming pieces 500 are rotatably matched with the rotating disk 200, and the limit stopper 600 is arranged above the blanking groove 301, and the two ends of the limit stopper 600 are respectively located in the two second positioning grooves 322, and the driving component 700 is connected with the rotating disk 200, and is used to drive the rotating disk 200 to rotate. When the driving component 700 drives the rotating disk 200, it can sequentially drive the first forming piece 400 to move in a direction away from the limit stopper 600 and the two second forming pieces 500 to move in a direction away from the limit stopper 600, so that the finished product falls from the blanking groove 301 and the blanking hole; in this way, there is a time difference between the first forming piece 400 and the two second forming pieces 500 moving in a direction away from the limit stopper 600, thereby avoiding friction damage to the finished product when it is discharged, thereby protecting the surface of the product.

[0041] See also Figure 3 and Figure 10 In one embodiment, the rotating disk 200 is also provided with a plurality of cams, and the cams include a plurality of first cams 210 arranged near the mounting groove 201 and along the circumferential side of the mounting groove 201; the disk-type cam powder pressing and molding mechanism also includes a movable roller, and the movable roller includes a first movable roller 810; the first movable roller 810 includes a first body 812 and a first sliding portion 813 and a first connecting portion 811 extending along both ends of the first body 812; wherein the first connecting portion 811 is connected to the end of the first molding member 400, and the side wall of the first body 812 is in contact with the side of the first cam 210 away from the mounting groove 201.

[0042] Specifically, since the end of the first molded part 400 is always in contact with the limit block 600, and the side wall of the first body 812 is in contact with the side of the first cam 210 that is away from the mounting groove 201, when the driving assembly 700 drives the rotating disk 200 to rotate, the first cam 210 rotates with the rotating disk 200, and the first cam 210 will give a force to the first body 812, so that the first body 812 will also have a force on the first molded part 400, so that the first molded part 400 moves in the direction away from the limit block 600.

[0043] During discharge, after the first forming member 400 moves in a direction away from the limiting stopper 600 , the two second forming members 500 can clamp the finished product.

[0044] For further information, see Figure 11 In another embodiment, the cam includes a plurality of second cams 220 located at the edge of the rotating disk 200; the movable roller also includes two second movable rollers 820; the second movable roller 820 includes a second body 822 and a second sliding portion 823 and a second connecting portion 821 extending along both ends of the second body 822; wherein, the two first cams 210 respectively correspond to the two second cams 220 to form two sliding grooves 202, the two second movable rollers 820 are respectively arranged in the two sliding grooves 202, the second connecting portions 821 of the two second movable rollers 820 are respectively connected to the ends of the two second molded parts 500, and when the rotating disk 200 rotates, at least one side wall of the two sliding grooves 202 contacts the side wall of the second body 822.

[0045] Specifically, a first cam 210 and a second cam 220 can form a sliding groove 202, so that a sliding groove 202 has two side walls, one of which is the side wall of the first cam 210 facing away from the mounting groove 201, and the other side wall is the side wall of the second cam 220 facing the mounting groove 201. The two second movable rollers 820 are respectively arranged in the two mounting grooves 201. During the discharge process, when the driving assembly 700 drives the rotating disk 200 to rotate, the first cam 210 rotates with the rotating disk 200, and the side wall of the first cam 210 facing away from the mounting groove 201 contacts the side wall of the second body 822, so that the second cam 220 can give a force to the second movable roller 820, and then the second movable roller 820 correspondingly gives a force to the second molded member 500, so that the second molded member 500 moves in a direction away from the limit stopper 600.

[0046] When pressing the material, the driving assembly 700 rotates with the rotating disk 200, and the rotating disk 200 rotates with the second cam 220. The second cam 220 contacts the second body 822 toward the side wall of the mounting groove 201, so that the second cam 220 can give a force to the second movable roller 820, and then the second movable roller 820 gives a force to the second molding member 500 accordingly, so that the second molding member 500 moves toward the direction close to the limit block 600, so that the second molding member 500 extrude the powder.

[0047] In a preferred embodiment, the first cam 210 is provided with a first arc surface 211 on a side away from the mounting groove 201; the second cam 220 is provided with a second arc surface 221 on a side facing the mounting groove 201. Specifically, in this embodiment, the first arc surface 211 and the second arc surface 221 are both smooth arc surfaces. The first arc surface 211 reduces the friction between the first cam 210 and the first body 812 and the second body 822, and the second arc surface 221 reduces the friction between the second cam 220 and the second body 822.

[0048] It is understandable that when discharging, the first molded piece 400 and the two second molded pieces 500 both move in the direction away from the limit block 600. It should be noted that after the first molded piece 400 first moves in the direction away from the limit block 600, the rotating disk 200 drives the two second molded pieces 500 to move in the direction away from the limit block 600. In order to achieve the above purpose, the positions of the first cam 210 and the second cam 220 can be designed according to actual conditions. For example, the first cam 210 in contact with the first movable roller 810 can be closer to the edge of the rotating disk 200 relative to the remaining first cam 210. In addition, the direction of the force can be adjusted by controlling the angles of the first arc surface 211 and the second arc surface 221, so that the first molded piece 400 and the two second molded pieces 500 have a time difference.

[0049] In order to prevent the second molded member 500 from easily falling off from the second positioning groove 322, please refer to Figure 6 and Figure 8 In one embodiment, the disc cam powder pressing molding mechanism also includes two limit plates 900, and the two limit plates 900 are respectively arranged above the two second molding parts 500 and fixed on the top surface of the molding part 320; the two limit plates 900 are respectively provided with avoidance gaps 910 corresponding to the two second positioning grooves 322; the two limit plates 900 are also respectively provided with two limit grooves 920 corresponding to the connecting parts of the two second movable rollers 820, and the two second connecting parts 821 are respectively provided in the two limit grooves 920.

[0050] Specifically, the limiting plate 900 can prevent the second forming member 500 from falling off the second positioning groove 322. At the same time, since the second forming member 500 also needs to move along the length direction of the second positioning groove 322, an avoidance notch 910 is provided on the limiting plate 900. The limiting groove 920 on the limiting plate 900 is provided along the length direction of the second positioning groove 322. The end of the second forming member 500 is connected to the connecting portion of the second movable roller 820, and the connecting portion is limited in the limiting groove 920, so that the second forming member 500 moves along the length direction of the second positioning groove 322.

Specifically, the extrusion body 931 is installed on the mounting table 100. As for the connection between the other end of the pressing column 934 and the first forming member 400, it can be an abutment, or the pressing column 934 can also be connected to the end of the first forming member 400 away from the limiting block 600 by means of threaded engagement, bolt connection, etc.

[0053] Please refer to Figure 7 , in an embodiment, a stepped surface 401 is provided at one end of the first forming member 400 close to the limiting block 600 for placing the product. Specifically, the bottom wall of the second positioning groove 322 and the stepped surface 401 are at the same height. In this way, after the first forming member 400 abuts against the limiting block 600, when driving the two second forming members 500 to extrude the powder, the powder can also be manually extruded on the top surface of the powder, so that the powder is formed.
