A stamping forming apparatus for metal powder products

Abstract

This utility model relates to the technical field of stamping forming equipment, and discloses a stamping forming equipment for metal powder products, including a fixed frame. An electric push rod is fixedly connected to the bottom of the inner cavity of the fixed frame. The tail end of the electric push rod passes through the fixed frame and extends into the interior of the fixed frame, where it is fixedly connected to an inclined block. This utility model, by setting up an inclined block, rollers, a connecting plate, a vertical rod, and a fixed sleeve, allows the inclined block to move horizontally backward when the electric push rod starts running. This causes the inclined block to squeeze the rollers, causing the rollers to roll and rise along the inclined surface at the top of the inclined block. This causes the connecting plate to drive the stamping die and the vertical rod to move vertically upward under the limiting action of the fixed sleeve. When the electric push rod extends to its longest position and causes the inclined block to begin to retract, it begins to fall back under the weight of the connecting plate and the vertical rod, completing the vibration cycle and thus achieving the function of uniformly spreading the powder.

Description

Technical Field

[0001] This utility model relates to the field of stamping forming equipment technology, and more specifically, to a stamping forming equipment for metal powder products. Background Technology

[0002] Stamping forming equipment is a mechanical device that uses a mold to apply high pressure to metal or non-metal materials to plastically deform them. It is widely used in the automotive, electronics, and home appliance industries. Its core consists of a machine body, transmission mechanism, mold, and control system. It achieves fast and precise punching, bending, and stretching processes through mechanical or hydraulic drive. It has advantages such as high production efficiency, low cost, and good product consistency. At the same time, it can be equipped with automatic feeding and safety protection systems to adapt to the needs of modern intelligent manufacturing and meet the production requirements of large-volume, high-precision parts.

[0003] A search revealed that CN217701349U discloses a powder forming machine's stamping mechanism, which raises the issue that "the current stamping mechanism inside the forming machine is relatively simple, only having basic stamping functions, making it inconvenient to quickly change the mold." The device uses a rotating wheel to drive a screw, which in turn moves a clamping plate to the front of the bottom mold frame. Bolts are then used to fix the bottom mold inside the frame. However, before powder stamping, this device lacks a structure to help evenly spread the powder inside the bottom mold, resulting in uneven density in the powder-stamped product. This leads to insufficient local strength in the sintered parts, making them prone to breakage or deformation. Therefore, improvements are needed. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a stamping and forming device for metal powder products, which has the advantage of uniformly spreading powder.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stamping forming device for metal powder products, comprising a fixed frame, an electric push rod fixedly connected to the bottom of the inner cavity of the fixed frame, the tail end of the electric push rod penetrating the fixed frame and extending into the interior of the fixed frame and fixedly connected to an inclined block, the bottom of the inclined block being slidably connected to the bottom of the inner cavity of the fixed frame, a connecting plate movably connected to the top of the fixed frame, a roller mounted on the bottom of the connecting plate via a rotating shaft, the bottom of the outer surface of the roller rolling in contact with the top of the inclined block, a stamping die movably connected to the inside of the connecting plate, and vertical rods fixedly connected to the four corners of the bottom of the connecting plate, the bottom ends of the vertical rods being slidably connected to the bottom of the inner cavity of the fixed frame, a fixed sleeve movably sleeved on the outer surface of the vertical rods, the bottom of the fixed sleeve being fixedly connected to the bottom of the inner cavity of the fixed frame.

[0006] As a preferred technical solution of this utility model, rectangular blocks are fixedly connected to the left and right sides of the top of the connecting plate. A threaded rod is threaded inside the rectangular block. The other end of the threaded rod passes through the rectangular block and extends to the outside of the rectangular block and is connected to a pressing plate through a bearing. Limiting rods located on the left and right sides of the threaded rod are fixedly connected to the outer surface of the pressing plate. The other end of the limiting rod passes through the rectangular block and extends to the outside of the rectangular block and slides with the inner surface of the rectangular block.

[0007] As a preferred embodiment of this utility model, an anti-slip pad is fixedly connected to the inner side of the extrusion plate, and the outer surface of the anti-slip pad is in close contact with the outer surface of the stamping die.

[0008] As a preferred technical solution of this utility model, protective shells are fixedly connected to the left and right sides of the top of the fixed frame. A motor is fixedly installed inside the protective shell. A rotating shaft is fixedly sleeved at the other end of the motor output shaft. A rotating rod is fixedly sleeved at the other end of the rotating shaft. A hollow rod is connected to the outer surface of the rotating rod through a cam mechanism.

[0011] As a preferred technical solution of this utility model, the top of the stamping upper die is fixedly connected with fixed rods located on the left and right sides of the hydraulic cylinder, and the other end of the fixed rod passes through the connecting frame and extends to the outside of the connecting frame and slides with the inner surface of the connecting frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention, by setting up an inclined block, rollers, connecting plate, vertical rod, and fixing sleeve, causes the inclined block to move horizontally backward when the electric push rod starts running. This causes the inclined block to squeeze the rollers, making the rollers roll and rise along the inclined surface at the top of the inclined block. This causes the connecting plate to drive the stamping die and the vertical rod to move vertically upward under the limiting action of the fixing sleeve. When the electric push rod extends to its longest state and causes the inclined block to begin to retract, it begins to fall back under the self-weight of the connecting plate and the vertical rod, realizing a vertical vibration cycle. This achieves the function of evenly spreading powder and ensures the quality of subsequent stamping operations. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 5As shown, this utility model provides a stamping forming device for metal powder products, including a fixed frame 1. An electric push rod 2 is fixedly connected to the bottom of the inner cavity of the fixed frame 1. The tail end of the electric push rod 2 passes through the fixed frame 1 and extends into the interior of the fixed frame 1, and is fixedly connected to an inclined block 3. The bottom of the inclined block 3 is slidably connected to the bottom of the inner cavity of the fixed frame 1. A connecting plate 5 is movably connected to the top of the fixed frame 1. A roller 4 is mounted on the bottom of the connecting plate 5 through a rotating shaft. The bottom of the outer surface of the roller 4 rolls in contact with the top of the inclined block 3. A stamping die 6 is movably connected to the inside of the connecting plate 5. The four sides of the bottom of the connecting plate 5 are... Vertical rods 7 are fixedly connected at each corner. The bottom end of the vertical rod 7 is slidably connected to the bottom of the inner cavity of the fixed frame 1. A fixed sleeve 8 is movably sleeved on the outer surface of the vertical rod 7. The bottom of the fixed sleeve 8 is fixedly connected to the bottom of the inner cavity of the fixed frame 1. Both the connecting plate 5 and the vertical rod 7 are made of stainless steel. When the electric push rod 2 starts to run, it will cause the inclined block 3 to move horizontally backward, thereby causing the inclined block 3 to squeeze the roller 4. While the roller 4 is rolling, it is lifted along the inclined surface at the top of the inclined block 3, thereby causing the connecting plate 5 to drive the stamping die 6 and the vertical rod 7 to move vertically upward under the limiting action of the fixed sleeve 8.

[0022] Rectangular blocks 9 are fixedly connected to the left and right sides of the top of the connecting plate 5. A threaded rod 10 is threaded inside the rectangular block 9. The other end of the threaded rod 10 passes through the rectangular block 9 and extends to the outside of the rectangular block 9 and is connected to the extrusion plate 11 through a bearing. Limiting rods 13 located on the left and right sides of the threaded rod 10 are fixedly connected to the outer surface of the extrusion plate 11. The other end of the limiting rod 13 passes through the rectangular block 9 and extends to the outside of the rectangular block 9 and slides with the inner surface of the rectangular block 9. When the threaded rod 10 is rotated, the extrusion plate 11 will drive the limiting rod 13 to move horizontally under the limiting action of the rectangular block 9.

[0023] Among them, an anti-slip pad 12 is fixedly connected to the inner side of the extrusion plate 11, and the outer surface of the anti-slip pad 12 is in close contact with the outer surface of the stamping die 6. The anti-slip pad 12 is made of rubber. This design not only avoids the situation where the clamping force of the extrusion plate 11 is too large and scratches the stamping die 6, but also improves the fixing effect of the stamping die 6 and prevents the stamping die 6 from sliding.

[0024] The top left and right sides of the fixed frame 1 are fixedly connected to protective shells 14. A motor 15 is fixedly installed inside the protective shell 14. A rotating shaft 16 is fixedly sleeved at the other end of the output shaft of the motor 15. A rotating rod 17 is fixedly sleeved at the other end of the rotating shaft 16. A hollow rod 18 is connected to the outer surface of the rotating rod 17 through a cam mechanism. When the motor 15 starts running, the rotating shaft 16 will drive the rotating rod 17 to rotate synchronously, so that the rotating rod 17 pushes the hollow rod 18 through the cam mechanism, causing the hollow rod 18 to move horizontally.

[0025] The top left and right sides of the fixed frame 1 are fixedly connected to fixed plates 20. The inside of the fixed plate 20 is slidably fitted with a striking rod 19. The outside of the striking rod 19 passes through the fixed plate 20 and extends to the outside of the fixed plate 20 and is fixedly connected to the outer surface of the hollow rod 18. When the two hollow rods 18 start to move, they will drive the two striking rods 19 to move horizontally towards each other under the limiting action of the fixed plate 20, and finally achieve the striking effect on the left and right sides of the stamping die 6.

[0026] The top of the fixed frame 1 is fixedly connected to the connecting frame 21, and the top of the connecting frame 21 is fixedly connected to the hydraulic cylinder 22. The bottom end of the hydraulic cylinder 22 passes through the connecting frame 21 and extends to the bottom of the connecting frame 21 and is fixedly connected to the upper stamping die 23. When the hydraulic cylinder 22 is activated, the upper stamping die 23 moves vertically downward, thereby achieving the stamping forming effect of metal powder in the inner cavity of the lower stamping die 6.

[0027] The upper stamping die 23 is fixedly connected to the top of the upper stamping die 23 and fixed rods 24 located on the left and right sides of the hydraulic cylinder 22. The other end of the fixed rod 24 passes through the connecting frame 21 and extends to the outside of the connecting frame 21 and slides with the inner surface of the connecting frame 21. Due to the limiting effect of the fixed rod 24, the upper stamping die 23 is prevented from being misaligned during the stamping process.

[0028] Working principle and usage process of this utility model:

[0029] Hydraulic cylinder 22 is pre-activated, causing upper stamping die 23 to descend. The position of lower stamping die 6 is adjusted so that upper stamping die 23 and lower stamping die 6 are aligned. Then, by rotating threaded rod 10, extrusion plate 11 drives anti-slip pad 12 and limiting rod 13 to move closer to lower stamping die 6 under the limiting action of rectangular block 9, thus fixing lower stamping die 6. At this point, upper stamping die 23 is reset. Simultaneously, metal powder is added, and electric push rod 2 is activated, causing inclined block 3 to move horizontally backward, thereby allowing the inclined block to... Block 3 presses against roller 4. At the same time, roller 4 rolls and rises along the inclined surface at the top of inclined block 3. This causes connecting plate 5 to drive stamping die 6 and vertical rod 7 to move vertically upward under the limiting action of fixed sleeve 8. When electric push rod 2 extends to its longest state and drives inclined block 3 to retract, it begins to fall back under the self-weight of connecting plate 5 and vertical rod 7, realizing vertical vibration cycle, thereby achieving the function of evenly spreading metal powder and ensuring the quality of subsequent stamping operations.

[0030] Simultaneously, two motors 15 are activated, causing the rotating shaft 16 to drive the rotating rod 17 to rotate synchronously. This causes the rotating rod 17 to push the hollow rod 18 through the cam mechanism. The hollow rod 18 then drives the striking rod 19 to move horizontally towards the lower stamping die 6 under the limiting action of the fixed plate 20. Finally, the metal powder is evenly spread by the striking assistance of the two striking rods 19. The spreading efficiency is improved by combining vertical vibration to loosen large particles with horizontal striking to compact the corners. The striking rod 19 has a quick return characteristic, with a fast return speed, reducing idle time and improving overall work efficiency. After the metal powder is spread, the hydraulic cylinder 22 is activated again, causing the upper stamping die 23 to move vertically downward under the limiting action of the fixed rod 24, ultimately realizing the stamping and forming of the metal powder.
