This equipment adopts an upper two-lower three-mold frame design, providing a maximum pressing pressure of 140 tons; it is mainly used in the forming and processing of materials such as metal powders and ceramic powders. A powder forming machine generally includes a feeding mechanism, a pressing mechanism, a demolding mechanism, and a control system. The feeding mechanism feeds the powder into the pressing mold, the pressing mechanism shapes the powder, and the demolding mechanism demolds the formed product.

[0003] To ensure the amount of material fed through the feeding mechanism, existing feeding mechanisms are designed with quantitative feeding technology. However, this quantitative feeding design is generally only for a single product. If different products need to be produced on the same equipment, the entire feeding mechanism needs to be replaced, which is relatively time-consuming and labor-intensive, and there is room for improvement. Utility Model Content

The feed plate is provided with a feed hole. It also includes a quantitative feeding plate disposed between the powder box and the feed plate, a drive mechanism connected to the quantitative feeding plate to drive the quantitative feeding plate to move, and an adjustment mechanism mounted on the mounting frame to adjust the distance between the powder box and the feed plate when changing quantitative feeding plates of different sizes. The bottom of the powder box, the quantitative feeding plate, and the feed plate abut against each other in sequence. The quantitative feeding plate is provided with a quantitative hole. In the feeding state, the driving mechanism drives the quantitative feeding plate to position the quantitative hole under the powder box for feeding; in the feeding state, the driving mechanism drives the quantitative feeding plate to move the quantitative hole that has been fed to the corresponding feeding hole for feeding.

[0006] Preferably, the adjusting mechanism includes a first connecting pipe detachably connected to the powder box or detachably connected to the feed pipe, a second connecting pipe connected to the first connecting pipe and capable of relative movement with the first connecting pipe, and a locking structure for locking the first connecting pipe and the second connecting pipe together.

[0007] Preferably, the locking structure includes an external thread on the outer wall of the first connecting pipe and an internal thread on the inner wall of the second connecting pipe, wherein the second connecting pipe is sleeved on the first connecting pipe and the first connecting pipe is threadedly connected to the second connecting pipe.

[0011] Preferably, there are two connecting rods, and a stabilizing rod is fixedly connected between the two connecting rods. The stabilizing rod is perpendicular to the connecting rod.

[0012] Preferably, the driving mechanism further includes a driving bracket, one side of which is fixedly connected to the driving component and the other side is detachably connected to the connecting rod.

[0015] In summary, this application includes at least one of the following beneficial technical effects: 1. When it is necessary to produce products of different sizes, there is no need to disassemble and replace the entire feeding mechanism. Only the quantitative feeding plate of the required size and thickness needs to be replaced. After the replacement is completed, the powder box, quantitative feeding plate and feeding plate are pressed together in sequence by adjusting the mechanism to feed the material. The operation is more convenient and greatly reduces time costs.

[0016] 2. The adjustment mechanism can adjust the distance between the powder box and the feed plate. The height is adjusted by means of threaded connection, which makes the adjustment process more convenient and accurate and reduces the difficulty of adjustment. In addition, the first connecting pipe and the second connecting pipe are further locked by locking nut to ensure the stability of the feeding process and reduce the risk of feeding failure.

Sub-plate; Detailed Implementation

[0023] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0024] This application discloses a quantitative feeding mechanism, specifically including a mounting frame 1, a feed pipe 2, a powder box 3, a feed plate 4, a quantitative feeding plate 5, and a driving mechanism 6. Powder is conveyed into the powder box 3 through the feed pipe 2. The driving mechanism 6 then drives the quantitative feeding plate 5 to the lower side of the powder box 3 to obtain the corresponding amount of powder. Finally, the driving mechanism 6 moves the quantitative feeding plate 5 onto the feed plate 4 for feeding, thus achieving the overall quantitative feeding function.

[0025] The feed pipe 2 is mounted on the mounting frame 1. The feed pipe 2 can be directly fixed to the mounting frame 1, or it can be installed on other components first and then onto the mounting frame 1, depending on the actual situation. In this embodiment, it is preferred to install it on other components first and then onto the mounting frame 1. Additionally, the powder box 3 is installed inside the feed pipe 2 and is connected to the feed pipe 2, ensuring that the powder can directly enter the powder box 3 for storage, facilitating feeding. The powder box 3 and the feed pipe 2 can be integrally connected or separately installed and fixed by a fixing mechanism; the specific method is not specifically limited in this embodiment.

[0026] A feeding plate 4 is located below the powder box 3. The feeding plate 4 has multiple feeding holes 41 evenly distributed on it. The specific location and number of feeding holes 41 are designed according to actual production needs. A quantitative feeding plate 5 is located between the powder box 3 and the feeding plate 4. The quantitative feeding plate 5 has quantitative holes 51 that correspond to the feeding holes 41. A driving mechanism 6 is connected to the quantitative feeding plate 5 to drive its movement. During the movement of the quantitative feeding plate 5, the driving mechanism 6 ensures that the quantitative holes 51 on the quantitative feeding plate 5 are aligned with the feeding holes 41, thereby achieving precise feeding.

[0027] The quantitative feeding mechanism also includes an adjustment mechanism 7 mounted on the mounting frame 1, which adjusts the distance between the powder box 3 and the feed plate 4 when changing quantitative feeding plates 5 of different sizes. Through the adjustment mechanism 7, the bottom of the powder box 3, the quantitative feeding plate 5, and the feed plate 4 are sequentially contacted during the process of changing quantitative feeding plates 5 of different sizes. In the feeding state, the drive mechanism 6 drives the quantitative feeding plate 5 so that the quantitative hole 51 is located on the lower side of the powder box 3 for feeding. In the feeding state, the drive mechanism 6 drives the quantitative feeding plate 5 to move the quantitative hole 51 after feeding to the corresponding feed hole 41 for feeding.

[0028] In one embodiment, the drive mechanism 6 includes a drive member 61 mounted on the mounting frame 1 and a linkage member 62 detachably connected between the drive member 61 and the quantitative feeding plate 5. The drive member 61 drives the linkage member 62 to move the quantitative feeding plate 5.

[0029] Among them, the driving component 61 is preferably a slide cylinder. Using a slide cylinder can reduce the space occupation rate. The driving component 61 can also adopt other mechanisms that can achieve driving movement, which will not be described in detail here. In addition, the installation method between the driving component 61 and the mounting bracket 1 is determined according to the actual situation. In this embodiment, it is preferred to use bolt fixing to achieve installation.

[0030] The linkage 62 includes a connecting rod 621, one end of which is detachably connected to the quantitative feeding plate 5, and the other end is detachably connected to the driving component 61.

[0031] A mounting block 63 is fixedly installed on the quantitative feeding plate 5. A mounting lug 64 extends from the side of the mounting block 63 toward the connecting rod 621 and is bolted to the connecting rod 621. The connecting rod 621 is detachably connected to the quantitative feeding plate 5 through the mounting lug 64.

[0032] The drive mechanism 6 also includes a drive bracket 65, and the connecting rod 621 is detachably connected to the drive component 61 through the drive bracket 65. One side of the drive bracket 65 is fixedly connected to the drive component 61, and the other side is detachably connected to the connecting rod 621. Both the fixed connection and the detachable connection are achieved by bolting. The detachable structure can be selected according to the actual situation. In addition, both the drive component 61 and the drive bracket 65 are located on the lower side of the connecting rod 621, further reducing the space occupancy rate.

[0033] In one embodiment, two connecting rods 621 are provided, with the two connecting rods 621 located on both sides of the driving member 61, so that the quantitative feeding plate 5 can move stably along a preset trajectory during the driving process of the driving member 61; in addition, a stabilizing rod 622 is fixedly connected between the two connecting rods 621, and the stabilizing rod 622 is set perpendicular to the connecting rod 621. The stabilizing rod 622 can be directly integrated with the connecting rod 621, or it can be fixed by bolts. By adding the stabilizing rod 622, the overall movement stability is further improved.

[0034] In one embodiment, the feed plate 4 is provided with a limiting block 81 for restricting the movement position of the quantitative feeding plate 5. There are two limiting blocks 81, which are respectively located on both sides of the quantitative feeding plate 5 to restrict the movement trajectory of the positioning feeding plate. The limiting blocks 81 are detachably fixed to the feed plate 4 by bolts. Whether or not to install the limiting blocks 81 can be selected according to the actual situation.

[0035] The adjusting mechanism 7 includes a first connecting pipe 71 that is detachably connected to the powder box 3 or detachably connected to the feed pipe 2, a second connecting pipe 72 that is connected to the first connecting pipe 71 and can move relative to the first connecting pipe 71, and a locking structure 73 that locks the first connecting pipe 71 and the second connecting pipe 72 together.

[0036] The connection position of the first connecting pipe 71 can be adopted in several ways. One is to detachably and fixedly connect it to the powder box 3, and the other is to detachably connect it to the feed pipe 2. In this embodiment, it is preferred to detachably connect it to the feed pipe 2. The detachable connection between the first connecting pipe 71 and the feed pipe 2 can be achieved by threaded connection. That is, the feed pipe 2 is sleeved on the first connecting pipe 71, the inner wall of the feed pipe 2 has internal threads, and the outer wall of the first connecting pipe 71 has external threads. The detachable connection between the feed pipe 2 and the first connecting pipe 71 is achieved by threaded connection. Depending on the actual situation, a nut can also be added for tightening and locking. The detachable connection between the first connecting pipe 71 and the feed pipe 2 can also be achieved by the mutual snapping of buckles and slots. The specific choice depends on the actual situation.

[0037] There are several ways to set the locking structure 73. One way is to have the first connecting pipe 71 and the second connecting pipe 72 sleeved and slidably connected, with a locking hole on the second connecting pipe 72. A bolt is threaded into the locking hole, and the first connecting pipe 71 is locked by the bolt after the first connecting pipe 71 and the second connecting pipe 72 are adjusted to the appropriate position. Another way is to have the first connecting pipe 71 and the second connecting pipe 72 threadedly connected, and the vertical position can be adjusted by rotating them. This embodiment preferably adopts this solution, which specifically includes an external thread on the outer wall of the first connecting pipe 71 and an internal thread on the inner wall of the second connecting pipe 72. The second connecting pipe 72 is sleeved on the first connecting pipe 71 and the first connecting pipe 71 and the second connecting pipe 72 are threadedly connected. The first connecting pipe 71 and the second connecting pipe 72 can move relative to each other, thereby realizing the telescopic function, and thus adjusting the height of the powder box. When using different sizes of quantitative feeding plates 5, it can be ensured that the powder box is always pressed against the quantitative feeding plate 5.

[0038] In addition, the locking structure 73 may also include a locking nut 731, which is sleeved and threaded onto the first connecting pipe 71 and abuts against the second connecting pipe 72. The locking nut 731 can completely lock the threaded first connecting pipe 71 and the second connecting pipe 72, preventing rotation or other movement and improving the stability of the structure.

[0039] To ensure the stability of the second connecting pipe 72, a mounting platform 82 is provided on the mounting bracket 1 for the fixed installation of the second connecting pipe 72. In one embodiment, the second connecting pipe 72 is fixedly installed on the mounting platform 82 by bolts, which improves the stability of the first connecting pipe 71 and the second connecting pipe 72 during relative movement. In another embodiment, the second connecting pipe 72 is installed on the mounting platform 82 by rotational connection, which can improve the convenience of adjusting the relative positions of the second connecting pipe 72 and the first connecting pipe 71 by rotation. Specifically, it is only necessary to fix a bearing on the mounting platform 82, and fix the second connecting pipe 72 to the inner ring of the bearing to achieve rotation.

[0040] The quantitative feeding plate 5 can be formed in one piece or formed by stacking several sub-plates 83. If it is formed in one piece, the quantitative feeding plate 5 of different sizes can be replaced during the replacement process. If the sub-plates 83 are stacked, the size can be adjusted by adjusting the number of sub-plates 83 stacked, thereby improving production efficiency.

[0041] In this embodiment, the sub-plates 83 are preferably stacked. That is, the quantitative feeding plate 5 includes a number of sub-plates 83 stacked on each other and locking components that lock the sub-plates 83. Each sub-plate 83 has a corresponding locking hole, and the locking component is preferably a bolt. By cooperating with the locking component and the locking hole, all the sub-plates 83 are fixed, and then spliced ​​together to form quantitative feeding plates 5 of different sizes.

[0042] The implementation principle of the quantitative feeding mechanism in this application embodiment is as follows: when it is necessary to produce products of different sizes, it is not necessary to disassemble and replace the entire feeding mechanism. Only the quantitative feeding plate 5 of the required size and thickness needs to be replaced. After the replacement is completed, the powder box 3, the quantitative feeding plate 5 and the feeding plate 4 are pressed together in sequence by the adjustment mechanism 7, and the feeding can be carried out. The operation is more convenient and the time cost is greatly reduced.

[0043] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
