[0046] Base 100, wherein the base 100 is horizontally positioned;

[0047] A stamping platform 200 is horizontally positioned above the base 100, and a vertically penetrating die hole 210 is provided in the center of the stamping platform 200.

[0048] A support adjustment component 300 is disposed on the base 100 and is used to support and adjust the height position of the stamping platform 200.

[0049] The first stamping component 400 is disposed on the base 100 and connected to the support adjustment component 300. The upper end of the first stamping component 400 is aligned with the die hole 210 and extends into the die hole 210 to form a die groove 220 on the upper surface of the stamping platform 200. The formed die groove 220 is used to place the material to be formed.

[0050] The second stamping component 500 is used to insert its lower end into the die hole 210 of the stamping platform 200 to stamp the material to be formed in the die groove 220.

[0051] A demolding component 600 is used to apply downward pressure to the stamping platform 200 to demold the molded product 700 in the mold groove 220.

[0052] The first stamping component 400 includes a first outer stamping component 410 and a first inner stamping component 420, which are movably sleeved together to adjust the shape of the die groove 220.

[0053] The second stamping component 500 includes a second outer stamping component 510 and a second inner stamping component 520, which are movably connected to each other for adjusting the molding shape of the multilayer composite material.

[0054] In this embodiment, the assembly and adjustment of various components are applicable to the three process stages of powder filling, blank forming and demolding of double-layer material columnar parts.

[0055] Specifically, the base 100 is cylindrical, with a vertically arranged support and adjustment component 300 on it, and a stamping platform 200 is arranged above the support and adjustment component 300.

[0056] During assembly, one end of the support adjustment component 300 is mounted on the upper end of the base 100, and the other end is designed to face the stamping platform 200. The height of the stamping platform 200 can be adjusted by manually adjusting the vertical height of the support adjustment component 300.

[0057] The stamping platform 200 is also cylindrical, with a vertically penetrating die hole 210 at its center. The die hole 210 provides a position for stamping powder materials. A first stamping component 400 is provided at the die hole 210 of the stamping platform 200. The first stamping component 400 includes a first outer stamping component 410 and a first inner stamping component 420. The first outer stamping component 410 and the first inner stamping component 420 are movably sleeved together, meaning they are detachably sleeved and installed, and their dimensions can be adjusted according to the size of the product to be stamped. The first outer stamping component 410 is a hollow cylindrical design, and the first inner stamping component 420 is a cylindrical design. The lower end of the inner punch component 420 is located on the upper end face of the base 100. The upper end of the first inner punch component 420 extends into the die hole 210 of the stamping platform 200 and is flush with the upper end of the stamping platform 200. The lower end of the first outer punch component 410 contacts the upper end of the adjusting stud 310 connected to the threaded holes 110 distributed circumferentially in the inner layer of the base 100. The upper end of the first outer punch component 410 extends into the die hole 210 of the stamping platform 200 and is slidably sleeved with the first outer punch component 410. The height of the first outer punch component 410 is adjusted by the adjusting stud 310 to form die grooves 220 of different depths on the upper end face of the stamping platform 200, such as... Figure 5As shown, the mold groove 220 is used to place the powder material to be formed. In this embodiment, it is used to form a double-layer material. Therefore, after the stamping platform 200 and the first stamping component 400 are assembled together, powder material A is filled into the formed mold groove 220 to achieve the first filling (inner layer filling).

[0058] After the stamping platform 200 and the first stamping component 400 are assembled and filled with material, the second stamping component 500 is installed on the upper end of the stamping platform 200. The second stamping component 500 includes a second outer stamping component 510 and a second inner stamping component 520. The second outer stamping component 510 is a hollow cylindrical design, and the second inner stamping component 520 is a cylindrical design. The second outer stamping component 510 and the second inner stamping component 520 are also movably sleeved, such as slidingly sleeved to each other. That is, the two are detachably sleeved and installed, and the corresponding dimensions are adjusted according to the size of the product to be stamped.

[0059] After the powder material is filled into the mold cavity 220 for the first time, the support adjustment component 300 on the base 100 is adjusted to raise the stamping platform 200, creating a certain height difference between it and the first outer punch component 410. Figure 7 As shown; then the second inner punch component 520 is assembled, as shown. Figure 8 As shown, at this time, the stamping platform 200 and the second inner stamping component 520 form a space; then, B powder material is filled into the space formed by the stamping platform 200 and the second inner stamping component 520 to achieve the second powder filling (outer layer filling), as shown. Figure 9 As shown.

[0060] After the powder filling is complete, adjust the support adjustment component 300 on the base 100 until the first outer punch component 410 is lowered to be flush with the first inner punch component 420, then stop adjusting. At this point, both powder A and powder B have been filled and are at the same height. Then, assemble the second outer punch component 510 onto the second inner punch component 520, as follows: Figure 10 As shown; then, appropriate pressure is applied to the second inner punch 520 and the second outer punch 510. The appropriate pressure value can be set by the press and the pressure is applied to the second inner punch 520 and the second outer punch 510 to press the powder material into shape and realize the blank forming process.

[0061] After the product is formed, remove the second inner punch 520 and the second outer punch 510, then adjust and remove the support adjustment component 300 on the base 100, and install the demolding component 600 on the upper surface of the stamping platform 200. The demolding component 600 applies downward pressure to the stamping platform 200, causing the formed product in the mold groove 220 to be demolded under the pressure. Figure 11 As shown, and Figure 12 It is a molded two-layer composite material.

[0062] In one embodiment, the support adjustment component 300 includes a plurality of adjustment studs 310;

[0063] The base 100 is provided with a plurality of threaded holes 110 corresponding to the adjusting stud 310;

[0064] Multiple adjusting studs 310 are vertically arranged between the base 100 and the stamping platform 200, and the threaded end of each adjusting stud 310 faces downward and is threadedly connected to the corresponding threaded hole 110 of the base 100. The level and / or height of the stamping platform 200 and the first outer punch component 410 can be adjusted by tightening or loosening the multiple adjusting studs 310.

[0065] Specifically, the multiple threaded holes 110 of the base 100 are circumferentially distributed in an outer layer and an inner layer on the upper end face of the base 100. The adjusting studs 310 connected to the threaded holes 110 of the outer layer are used to adjust the level and / or height of the stamping platform 200, and the adjusting studs 310 connected to the threaded holes 110 of the inner layer are used to adjust the height of the first outer punch component 410.

[0066] In this embodiment, refer to Figure 1 , Figure 2 The support adjustment component 300 includes multiple adjustment studs 310, and the base 100 is provided with multiple corresponding threaded holes 110. The multiple threaded holes 110 are arranged in an outer layer and an inner layer circumferentially spaced on the upper end face of the base 100. In this embodiment, there are six adjustment studs 310 and threaded holes 110, with three in the outer layer and three in the inner layer. The lower end of each adjustment stud 310 is inserted into the corresponding threaded hole 110 and threadedly connected to the threaded hole 110. The upper end face of the three adjustment studs 310 in the outer layer is in contact with the lower end face of the stamping platform 200 and is used to adjust the height and level of the stamping platform 200. The upper end face of the three adjustment studs 310 in the inner layer is in contact with the lower end face of the first outer stamping component 410 and is used to adjust the height of the first outer stamping component 410. It should be noted that the upper and lower end faces of the adjustment studs 310 in the inner layer are both planar to ensure the parallelism of the first outer stamping component 410.

[0067] When it is necessary to adjust the height and / or level of the stamping platform 200, the height and / or level of the stamping platform 200 can be adjusted by turning the three adjusting studs 310 located on the outer layer; when it is necessary to adjust the height of the first outer stamping component 410, the height of the first outer stamping component 410 can be adjusted by turning the adjusting studs 310 located on the inner layer.

[0068] In one embodiment, the demolding component 600 is an annular part, and three support claws 610 are evenly spaced around the lower end of the demolding component 600. The area between any two adjacent support claws 610 constitutes an outlet for removing the molded product 700.

[0069] In this embodiment, refer to Figure 2 The demolding component 600 is a ring-shaped part, which allows the demolding component 600 to be placed on the stamping platform 200 after the product is formed, and the stamping platform 200 to be pressed down so that the finished product is pushed upward by the forming punch, and the finished product can be taken out at the outlet formed between any two adjacent support claws 610.

[0070] In one embodiment, the upper end of the stamping platform 200 is provided with three limiting grooves 230, and the three limiting grooves 230 correspond one-to-one with the three supporting claws 610. Each limiting groove 230 is used for the lower end of the supporting claw 610 to extend into it.

[0071] In this embodiment, refer to Figure 4 By providing three limiting grooves 230 at the upper end of the stamping platform 200 that correspond one-to-one with the three support claws 610, the lower ends of the support claws 610 can be inserted when the stamping platform 200 is pressed down, so as to limit the movement and prevent the demolding component 600 from slipping when the stamping platform 200 is pressed down.

[0072] In the above embodiments, the molding method of the multilayer composite material is as follows:

[0073] First, install the corresponding adjusting stud 310 into the corresponding threaded hole 110 on the upper end face of the base 100, and then turn the adjusting stud 310 to adjust its height. Assemble the first outer punch 410 and the first inner punch 420 with the stamping platform 200. Place the first inner punch 420 on the base 100, the first outer punch 410 on the adjusting stud 310 inside the base 100, and the stamping platform 200 on the adjusting stud 310 outside the base 100. Adjust the first outer punch 410, the first inner punch 420, and the stamping platform 200 so that the first outer punch 410 and the first inner punch 420 are flush with the upper end face of the stamping platform 200. Then, adjust the adjusting stud 310 inside the base 100 to raise the first outer punch 410, creating a certain space between it and the first inner punch 420, thus forming a mold groove 220 on the stamping platform 200. Figure 5 As shown, powder material A is then placed into the formed mold groove 220 to achieve the first powder filling, as shown. Figure 6 As shown.

[0074] Then, adjust the height of the adjusting stud 310 on the outer layer of the base 100 so that the stamping platform 200 rises, creating a certain height difference with the first outer stamping component 410, such as... Figure 7 As shown; then the second inner punch component 520 is assembled, as shown. Figure 8 As shown, at this time, the stamping platform 200 and the second inner stamping component 520 form a space; then, B powder material is filled into the space formed by the stamping platform 200 and the second inner stamping component 520 to achieve the second powder filling, as shown. Figure 9 As shown.

[0075] After the powder filling is complete, adjust the adjusting stud 310 inside the base 100 until the first outer punch 410 is lowered to be flush with the first inner punch 420, then stop adjusting. At this point, both powder A and powder B have been filled and are at the same height. Then, assemble the second outer punch 510 onto the second inner punch 520, as follows: Figure 10 As shown, it is necessary to ensure that the lower end face of the second inner punch 520 is flush with the lower end face of the second outer punch 510.

[0076] Then, appropriate pressure is applied to the second inner punch 520 and the second outer punch 510.
