Description

Technical Field

[0001] This utility model relates to the field of powder metallurgy equipment technology, specifically to an energy-saving and environmentally friendly powder forming device. Background Technology

[0002] Powder metallurgy is a production technology that uses metal powders as raw materials to mass-produce complex-shaped products through pressing, forming, and sintering. The density of powder metallurgy products has a significant impact on their performance; as the density increases, the hardness, tensile strength, and fatigue strength of the product all increase. Based on density, powder metallurgy parts are generally classified as high-density powder metallurgy parts, with a density greater than 7.20 g·cm−3. High-density powder metallurgy parts are currently a very popular product in the market, effectively replacing traditional cast steel parts while maintaining the green and energy-saving manufacturing characteristics of powder metallurgy technology. They have wide applications in fields such as gearboxes and new energy vehicles.

[0003] In the existing Chinese patent CN202222245341.8, a powder metallurgy pressing device is introduced. When sealing plug one and sealing plug two move into the connecting sleeve at the same time, the powder will fill the space between sealing plug one and sealing plug two, so that the amount of powder delivered to the pressing device body each time tends to be consistent, thus improving the accuracy of powder delivery.

[0004] However, during use, the mounting sleeve has a slotted structure on its outer side for connecting with the external feeding structure. During pressing, the metal produced during pressing can clog this slot. Therefore, after pressing, the mounting sleeve needs to be removed to remove the metal, or the mounting sleeve can be fixed to the bottom structure, but this makes it difficult to remove the metal. Furthermore, the mounting sleeve is an open structure, which makes it easy for powder to float in the air during the pouring process, resulting in waste of raw materials, increased raw material costs, and pollution and damage to the surrounding air environment, reducing the utilization rate of metal dust. Utility Model Content

[0005] Technical problems to be solved

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an energy-saving and environmentally friendly powder forming device, which can effectively solve the problems in the existing technology.

[0007] Technical solution

[0008] This utility model provides an energy-saving and environmentally friendly powder forming device, including a processing table. A carrier plate is fixed to one side of the top of the processing table, and a pressing component is fixed to the top of the carrier plate. A feeding component is fixed to one side of the bottom of the processing table. The pressing component includes a pressure plate fixed to the top of the processing table, a hydraulic cylinder fixed to the bottom of the pressure plate, and a connecting plate connected to the output end of the hydraulic cylinder. One side of the connecting plate is connected and fixed to a feeding and discharging component. The feeding and discharging component includes a first support arm, a vertical rod fixed to the first support arm, and a second support arm fixed to the other end of the vertical rod. The top of the second support arm is fixedly connected to a bottom hydraulic cylinder, and the output end of the bottom hydraulic cylinder is fixedly connected to a top plate. A mold is placed on the top of the top plate. An inner groove is formed through the middle of the processing table and the carrier plate, and an outer groove is formed on the outer side of the bottom of the inner groove. The mold is set in the inner groove.

[0009] Furthermore, a hydraulic rod is fixed to the inner side of the carrier plate, and a pusher with an arc-shaped inner side is fixed to the end of the hydraulic rod.

[0010] Furthermore, the bottom hydraulic cylinder is fixedly connected to the second support arm via a mounting bracket.

[0011] Furthermore, the first support arm, the vertical rod, and the second support arm are all fixedly connected by bolts and nuts, and the first support arm is fixedly connected to the side of the connecting plate.

[0012] Furthermore, a protective plate is fixed to the top of the second support arm, and the protective plate is located on the outside of the top plate, and the size of the protective plate is adapted to the size of the outer groove.

[0013] Furthermore, a feed hole is provided on the side wall of the mold, and the size of the discharge port of the feed assembly is adapted to the size of the feed hole.

[0014] Beneficial effects

[0015] This invention utilizes a feeding and discharging assembly structure. Users can add metal powder through the bottom feeding assembly. When the equipment is not running, one side of the mold is connected to the discharge port of the feeding assembly via the feeding hole, allowing the powder to enter the mold. A hydraulic cylinder drives the connecting plate to move upwards, causing the first support arm, vertical rod, second support arm, and mounting frame to move upwards as well. This allows the mold to move upwards within the inner groove. When the hydraulic cylinder drives the connecting plate downwards, the aforementioned structures move downwards. When the mold reaches half its travel, the bottom hydraulic cylinder structure within the mounting frame drives the top plate upwards, propelling the mold upwards. During this movement, the outer side of the mold remains in contact with the end of the feeding assembly. Simultaneously, the guard plate moves synchronously, and upon reaching the middle of the outer groove, the internal space of the mold and the pressure within the connecting plate... The bottom of the pressing head contacts and presses the metal powder into a specified shape. The hydraulic cylinder structure moves upward, and the bottom hydraulic cylinder in the feeding and discharging assembly lifts upward, so the mold structure can protrude from the top of the carrier plate. Finally, the hydraulic rod structure on one side drives the push head structure to push the mold containing the pressed metal to one side. Then, another empty mold is placed in the guard plate to complete a cycle. Therefore, during use, when the feeding assembly is feeding the mold, the feeding hole will never be connected to the external space. After entering the inner tank, it can be sealed before powder pressing. Moreover, during the pressing process, the metal powder will not leak out. Therefore, the user can determine the length of the mold and the mounting frame as needed. Thus, molds of different lengths can be ejected through the mounting frame and the bottom hydraulic cylinder to achieve personalized metallurgical pressing function. Attached Figure Description

[0023] The present invention will be further described below with reference to the embodiments.

[0024] Example: An energy-saving and environmentally friendly powder forming device, see attached figure. Figure 1 -Appendix Figure 4 The system includes a processing table 1, a carrier plate 2 fixed to one side of the top of the processing table 1, a pressing assembly 4 fixed to the top of the carrier plate 2, and a feeding assembly 3 fixed to one side of the bottom of the processing table 1. The pressing assembly 4 includes a pressure plate 43 fixed to the top of the processing table 1, a hydraulic cylinder 41 fixed to the bottom of the pressure plate 43, and a connecting plate 42 connected to the output end of the hydraulic cylinder 41. One side of the connecting plate 42 is connected and fixed to a feeding and discharging assembly 5. The feeding and discharging assembly 5 includes a support arm 5. 1. A vertical rod 511 fixed to the first support arm 51 and a second support arm 512 fixed to the other end of the vertical rod 511. The top end of the second support arm 512 is fixedly connected to the bottom hydraulic cylinder 52. The output end of the bottom hydraulic cylinder 52 is fixedly connected to the top plate 522. A mold 53 is placed on the top end of the top plate 522. An inner groove 11 is opened through the middle of the processing table 1 and the carrier plate 2. An outer groove 12 is opened on the outer side of the bottom of the inner groove 11. The mold 53 is set in the inner groove 11.

[0025] A hydraulic rod 21 is fixed to the inner side of the carrier plate 2, and a pusher head 22 with an arc-shaped inner side is fixed to the end of the hydraulic rod 21. Through the feeding and discharging assembly 5 structure, the user can add metal powder into the interior through the bottom feeding assembly 3. When the equipment is not started, one side of the mold 53 is connected to the discharge port of the feeding assembly 3 through the feeding hole 531, so that the powder enters the mold 53. The hydraulic cylinder 41 drives the connecting plate 42 to move to the top, and then the first support arm 51, the vertical rod 511, the second support arm 512 and the mounting frame 521 move to the top, so that the mold 53 can move upward in the inner groove 11. When the hydraulic cylinder 41 drives the connecting plate 42 to move downward, the above structure moves downward. When it reaches half of the stroke, the bottom hydraulic cylinder 52 structure in the mounting frame 521 can drive the top plate 522 to drive the mold 53 to the top at this time.

[0026] The bottom hydraulic cylinder 52 is fixedly connected to the second support arm 512 via the mounting bracket 521; the first support arm 51, the vertical rod 511, and the second support arm 512 are all fixedly connected by bolts and nuts, and the first support arm 51 is fixedly connected to the side of the connecting plate 42; a guard plate 54 is fixed to the top of the second support arm 512, and the guard plate 54 is located on the outside of the top plate 522, and the size of the guard plate 54 is adapted to the size of the outer groove 12; a feed hole 531 is provided on the side wall of the mold 53, and the size of the discharge port of the feeding component 3 is adapted to the size of the feed hole 531; during the movement, the outer side of the mold 53 can always maintain contact with the end of the feeding component 3, and the guard plate 54 can move synchronously, and when it reaches the middle of the outer groove 12, the internal space of the mold 53 contacts the bottom of the pressing head in the connecting plate 42, and the metal powder is fed into the mold. The material is pressed into a specified shape, and the hydraulic cylinder 41 moves upward, while the bottom hydraulic cylinder 52 in the feeding and discharging assembly 5 lifts upward. Therefore, the mold 53 can protrude from the top of the carrier plate 2. Finally, the hydraulic rod 21 on one side drives the pusher 22 to push the mold 53 containing the pressed metal to one side. Then, another empty mold 53 is placed in the guard plate 54 to complete a cycle. Therefore, when the feeding assembly 3 is feeding the mold 53, the feeding hole 531 will never be connected to the external space. After entering the inner groove 11, it can be sealed before powder pressing. Moreover, during the pressing process, the metal powder will not leak out. Therefore, the user can determine the length of the mold 53 and the mounting bracket 521 as needed. Thus, the mounting bracket 521 and the bottom hydraulic cylinder 52 can be used to push out molds 53 of different lengths to achieve the function of personalized metallurgical pressing.

[0027] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
