Description

Technical Field

[0001] This utility model relates to the field of large-capacity powder feeding technology, and specifically discloses a large-capacity powder feeding mechanism for a powder forming servo press. Background Technology

[0002] Powder forming servo presses are key equipment in the fields of powder metallurgy and precision forming. Through a servo drive system, they precisely control parameters such as pressure, displacement, and speed to press raw materials such as metal powder and ceramic powder into blanks with specific shapes and densities. They are widely used in aerospace, automotive manufacturing, and construction machinery. Thanks to the high responsiveness and control precision of the servo system, this equipment can meet the forming requirements of complex structural parts. Especially when pressing ultra-large products, due to their large size and weight, a large amount of powder needs to be conveyed in each forming process, placing stringent requirements on the powder feeding mechanism's large-capacity storage and stable conveying capabilities.

[0003] In existing technologies, powder feeding in powder forming servo presses typically employs two methods: one is to directly transport the powder to the press's feed inlet via a conveyor, and the other is to manually add the powder directly to the feeding structure. However, these methods generally lack an integrated metering structure. To ensure that the amount of powder fed into the press cavity accurately matches product requirements, it is often necessary to pre-weigh the powder manually or with additional equipment before feeding. This not only increases production steps and extends the cycle of a single forming process but also reduces overall production efficiency. Furthermore, the feeding inlet of some equipment is designed to be relatively high to accommodate the overall structure of the press, requiring auxiliary tools or climbing for manual feeding, which is extremely inconvenient.

[0004] Therefore, a large-capacity powder feeding mechanism is needed in a powder forming servo press to solve the above problems. Utility Model Content

[0005] This utility model proposes a large-capacity powder feeding mechanism for a powder forming servo press, which can realize automatic metering without the need for manual pre-weighing, simplifying the work process, shortening the production cycle and improving production efficiency; and without the need for auxiliary tools or climbing to operate, effectively improving the convenience of operation.

[0006] This utility model is implemented as follows: a large-capacity powder feeding mechanism for a powder forming servo press includes a base plate and a servo press feed pipe. The upper side of the base plate is provided with a conveying mechanism, a metering mechanism and a lifting mechanism.

[0007] The conveying mechanism includes a powder feeding box, a first spiral rod is rotatably connected inside the powder feeding box, a first drive motor with its output end fixedly connected to the first spiral rod is installed on the outer wall of the powder feeding box, and a transfer pipe is connected between the powder feeding box and the feed pipe of the servo press.

[0008] The metering mechanism includes a support plate and a pressure plate located below the powder feeding box. A pressure sensor is fixedly installed between the support plate and the pressure plate. Two vertical rods are fixedly connected to the front and rear sides of the upper surface of the pressure plate. The upper ends of the two vertical rods on the same side are respectively fixedly connected to a mounting base. A storage cylinder is fixedly connected between the two mounting bases. A first circular hole is opened through the upper end of the powder feeding box. A discharge pipe with a solenoid valve is connected to the lower end of the storage cylinder through the first circular hole.

[0009] The lifting mechanism includes an inclined conveying cylinder, a second spiral rod rotatably connected inside the conveying cylinder, a second drive motor whose output end is fixedly connected to the second spiral rod installed on the outer wall of the conveying cylinder, a second circular hole opened at the upper end of the storage cylinder, and a bent pipe passing through the second circular hole connected to the outer wall of the conveying cylinder.

[0010] As a preferred embodiment of the large-capacity powder feeding mechanism of the powder forming servo press of this utility model, a vertical plate is fixedly connected to the upper end of the base plate, and an operation panel and controller are installed on the outer wall of the vertical plate.

[0011] As a preferred embodiment of the large-capacity powder feeding mechanism of the powder forming servo press of this utility model, both the front and rear ends of the outer wall of the powder feeding box are fixedly connected to retaining plates, and two vertical rods located on the same side pass through the two retaining plates respectively and are slidably connected to the retaining plates.

[0012] As a preferred embodiment of the large-capacity powder feeding mechanism of the powder forming servo press of this utility model, the inside of the storage cylinder is equipped with a conical guide hopper that communicates with the discharge pipe.

[0013] As a preferred embodiment of the large-capacity powder feeding mechanism of the powder forming servo press of this utility model, the base plate is fixedly connected to the powder feeding box by two first fixing plates, the support plate is fixedly connected to the outer wall of one of the first fixing plates, and a reinforcing rib is fixedly connected between the support plate and one of the first fixing plates.

[0014] As a preferred embodiment of the large-capacity powder feeding mechanism of the powder forming servo press of this utility model, the conveying cylinder is fixedly connected to the base plate by two second fixing plates.

[0015] As a preferred embodiment of the large-capacity powder feeding mechanism of the powder forming servo press of this utility model, the outer wall of the conveying cylinder is connected to a feeding pipe, and a feeding hopper is installed at the upper end of the feeding pipe.

[0016] The beneficial effects of this utility model are:

[0017] 1. After the powder is added into the conveying cylinder, the second drive motor is started to rotate the second screw, pushing the powder upward along the inclined conveying cylinder, and finally conveying it to the storage cylinder through the curved pipe. This lifting process does not require auxiliary tools or climbing, effectively improving the convenience of operation.

[0018] 2. As the weight of the powder in the storage hopper increases, the pressure is transmitted through the mounting base, vertical rod, and pressure plate to the pressure sensor for real-time detection. When the weight reaches the target, the controller immediately shuts off the second drive motor to stop feeding and opens the solenoid valve of the discharge pipe to discharge the powder into the powder delivery box. This process achieves automatic metering, eliminating the need for manual pre-weighing, simplifying work procedures, shortening the production cycle, and improving production efficiency.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0027] Please see Figures 1-5The large-capacity powder feeding mechanism of the powder forming servo press includes a base plate 1 and a servo press feed pipe 23. The upper side of the base plate 1 is provided with a conveying mechanism, a metering mechanism and a lifting mechanism.

[0028] The conveying mechanism includes a powder feeding box 2, a first screw rod 3 is rotatably connected inside the powder feeding box 2, a first drive motor 5 with its output end fixedly connected to the first screw rod 3 is installed on the outer wall of the powder feeding box 2, and a transfer pipe 24 is connected between the powder feeding box 2 and the feed pipe 23 of the servo press.

[0029] The metering mechanism includes a support plate 6 and a pressure plate 8 located below the powder feeding box 2. A pressure sensor 7 is fixedly installed between the support plate 6 and the pressure plate 8. Two vertical rods 9 are fixedly connected to the front and rear sides of the upper end of the pressure plate 8. The upper ends of the two vertical rods 9 on the same side are respectively fixedly connected to the mounting base 11. A storage cylinder 12 is fixedly connected between the two mounting bases 11. A first round hole 14 is opened through the upper end of the powder feeding box 2. The lower end of the storage cylinder 12 is connected to a discharge pipe 13 that passes through the first round hole 14 and is equipped with a solenoid valve.

[0030] The lifting mechanism includes an inclined conveying cylinder 17, a second spiral rod 18 is rotatably connected inside the conveying cylinder 17, a second drive motor 20 with its output end fixedly connected to the second spiral rod 18 is installed on the outer wall of the conveying cylinder 17, a second circular hole 15 is opened at the upper end of the storage cylinder 12, and a bent pipe 21 passing through the second circular hole 15 is connected to the outer wall of the conveying cylinder 17.

[0031] In this embodiment: First, the powder is added into the conveying cylinder 17. In the lifting mechanism, the second drive motor 20 starts, driving the second screw rod 18 inside the conveying cylinder 17 to rotate. The powder moves upward along the inclined conveying cylinder 17 under the push of the second screw rod 18, and is finally conveyed into the storage cylinder 12 through the curved pipe 21. During this process, due to the design of the lifting mechanism, no auxiliary tools or climbing are required, effectively improving operational convenience.

[0032] Meanwhile, the weight inside the storage cylinder 12 gradually increases. Since the two mounting seats 11 on the outer wall of the storage cylinder 12 are connected and fixed to the pressure plate 8 by four vertical rods 9, the pressure plate 8 applies a vertically downward pressure to the pressure sensor 7. The pressure sensor 7 detects the weight change in real time. The pressure sensor 7 transmits the weight signal to the controller 19. When the weight of the powder inside the storage cylinder 12 just reaches the target, the controller 19 immediately controls the second drive motor 20 to shut down, stopping the supply of powder to the powder feeding box 2; simultaneously, it controls the solenoid valve of the discharge pipe 13 to open, discharging the powder inside the storage cylinder 12 into the powder feeding box 2 through the discharge pipe 13. This achieves automatic metering, eliminating the need for manual pre-weighing, simplifying the work process, shortening the production cycle, and improving production efficiency.

[0033] Finally, in the conveying mechanism, the first drive motor 5 starts, driving the first screw rod 3 inside the powder feeding box 2 to rotate. The powder entering the powder feeding box 2 moves to the left under the push of the first screw rod 3, and is finally conveyed to the servo press feed pipe 23 through the transfer pipe 24 to complete the powder feeding process.

[0034] As a technical optimization of this utility model, a vertical plate is fixedly connected to the upper end of the base plate 1, and an operation panel 4 and a controller 19 are installed on the outer wall of the vertical plate.

[0035] In this embodiment, the support plate provides the mounting base for the operation panel 4 and the controller 19. The operation panel 4 is used by the operator to input working parameters and issue operating commands; the controller 19 receives the weight feedback signal transmitted by the pressure sensor 7 and the operating commands input by the operation panel 4, thereby controlling the operation of the first drive motor 5, the second drive motor 20, and the solenoid valve.

[0036] As a technical optimization of this utility model, the front and rear ends of the outer wall of the powder feeding box 2 are fixedly connected with retaining plates 10, and two vertical rods 9 located on the same side pass through the two retaining plates 10 respectively and are slidably connected to the retaining plates 10.

[0037] In this embodiment, the retaining plate 10 on the outer wall of the powder feeding box 2 provides a limiting effect on the vertical rod 9 that passes through it, preventing the vertical rod 9 from shifting laterally.

[0038] As a technical optimization of this utility model, a conical guide hopper 16 connected to the discharge pipe 13 is installed inside the storage cylinder 12.

[0039] In this embodiment, the conical guide bucket 16 inside the storage cylinder 12 is connected to the discharge pipe 13. Its conical structure guides the powder in the storage cylinder 12 to gather at the bottom, ensuring that the powder can smoothly enter the discharge pipe 13.

[0040] As a technical optimization of this utility model, two first fixing plates are fixedly connected between the base plate 1 and the powder feeding box 2, and the support plate 6 is fixedly connected to the outer wall of one of the first fixing plates. A reinforcing rib is fixedly connected between the support plate 6 and one of the first fixing plates.

[0041] In this embodiment: two first fixing plates between the base plate 1 and the powder feeding box 2 securely fix the powder feeding box 2 above the base plate 1. The height of the first fixing plates is determined according to the installation position of the powder feeding box 2. The support plate 6 is fixed to the outer wall of one of the first fixing plates. The reinforcing ribs between the two enhance the load-bearing capacity of the support plate 6 and ensure the support effect for the pressure sensor 7.

[0042] As a technical optimization of this utility model, two second fixing plates are fixedly connected between the conveying cylinder 17 and the base plate 1.

[0043] In this embodiment: by setting two second fixing plates, the conveying cylinder 17 is securely fixed to the upper side of the base plate 1, and the height of the second fixing plates is determined by the installation position of the conveying cylinder 17.

[0044] As a technical optimization of this utility model, the outer wall of the conveying cylinder 17 is connected to a feed pipe, and a feeding hopper 22 is installed at the upper end of the feed pipe.

[0045] In this embodiment: the feed pipe on the outer wall of the conveying cylinder 17 is connected to the feeding hopper 22. The operator can directly add the powder to the feeding hopper 22, and the powder enters the conveying cylinder 17 through the feed pipe.

[0046] The working principle and usage process of this utility model are as follows: First, the powder is added through the feeding hopper 22 and enters the conveying cylinder 17 through the feed pipe. In the lifting mechanism, the second drive motor 20 is started, driving the second screw rod 18 inside the conveying cylinder 17 to rotate. The powder moves upward along the inclined conveying cylinder 17 under the push of the second screw rod 18, and is finally conveyed into the storage cylinder 12 through the bend pipe 21. During this process, since the feeding hopper 22 is in a low position, no auxiliary tools or climbing are required, which effectively improves the convenience of operation.

[0047] Meanwhile, the weight inside the storage cylinder 12 gradually increases. Since the two mounting seats 11 on the outer wall of the storage cylinder 12 are connected and fixed to the pressure plate 8 by four vertical rods 9, the pressure plate 8 applies a vertically downward pressure to the pressure sensor 7. The pressure sensor 7 detects the weight change in real time. The pressure sensor 7 transmits the weight signal to the controller 19. When the weight of the powder inside the storage cylinder 12 just reaches the target, the controller 19 immediately controls the second drive motor 20 to shut down, stopping the supply of powder to the powder feeding box 2; simultaneously, it controls the solenoid valve of the discharge pipe 13 to open, discharging the powder inside the storage cylinder 12 into the powder feeding box 2 through the discharge pipe 13. This achieves automatic metering, eliminating the need for manual pre-weighing, simplifying the work process, shortening the production cycle, and improving production efficiency.

[0048] Finally, in the conveying mechanism, the first drive motor 5 starts, driving the first screw rod 3 inside the powder feeding box 2 to rotate. The powder entering the powder feeding box 2 moves to the left under the push of the first screw rod 3, and is finally conveyed to the servo press feed pipe 23 through the transfer pipe 24 to complete the powder feeding process.
