Description

Technical Field

[0001] The present invention relates to the technical field of integrated presses for weighing powder, adding powder, and forming, and particularly relates to a fully automatic integrated press for weighing powder, adding powder, and forming. Background Art

[0002] Currently, the main equipment for magnet powder forming metallurgy processing is a magnetic field press. When processing rare earth magnetic powder into blocks, the raw materials should first be screened and weighed, and the pre-prepared magnetic powder should be added to the mold box of the press for forming.

[0003] In the existing fully automatic integrated press for weighing powder, adding powder, and forming, a powder adding hopper is provided inside. Often, a vibrating machine is installed to push the powder in the powder adding hopper to fall. It relies on a large-structured vibration dropping structure, consumes more energy, and cannot ensure that the material falls into the forming pressure cylinder quickly. Summary of the Invention

[0004] The present invention aims at the above problems and proposes a fully automatic integrated press for weighing powder, adding powder, and forming, which solves the defects of the existing one that relies on a large-structured vibration dropping structure, consumes more energy, and cannot ensure that the material falls into the forming pressure cylinder quickly.

The forming module includes a forming pressure cylinder. The linear module includes a sliding table, and a moving component is installed on the sliding table. The powder weighing module includes a feeding hopper and a powder weighing hopper. The powder weighing hopper is located directly below the feeding hopper. The powder adding device includes a powder adding hopper, and the powder adding hopper is placed on the moving component. A driving mechanism is installed on the linear module, and the driving mechanism is used to drive the moving component to move horizontally. After the moving component moves, a first working position and a second working position are respectively formed on the sliding table. When the moving component is at the first working position, the powder adding hopper is located directly below the powder weighing hopper, and when the moving component is at the second working position, the powder adding hopper is located above the forming pressure cylinder; The powder adding hopper includes a hopper body, and a flexible first air inlet pipe is provided at the inner end of the hopper body for pushing the powder into the forming pressure cylinder.

[0007] By opening the second air inlet pipe and the first air inlet pipe, the gas introduced into the second air inlet pipe causes the elastic bladder to bulge, and its protruding elastic sheet cooperates with the cover plate to form a funnel-shaped channel. According to the Bernoulli effect, it is convenient for the air flow in the first air inlet pipe to orderly flow the powder outwards into the forming pressure cylinder instead of scattering elsewhere. It replaces the large-structured vibration dropping structure, is more energy-saving, and the structure is further simplified. It ensures that the material falls into the forming pressure cylinder quickly.

[0026] Embodiment 1

[0027] The technical solution adopted by the present invention is as follows:

[0028] As Figure 1 and Figure 2 shown, the present invention discloses an integrated press for fully automatic powder weighing, powder adding and forming, including: a machine body 100, a plurality of linear modules 200, a plurality of powder weighing modules 300, a plurality of powder adding modules 400 and a plurality of forming modules 500 are provided at the bottom of the machine body. The forming module includes a forming pressing cylinder 1, the linear module includes a sliding table 2, a moving component 3 is installed on the sliding table. The powder weighing module includes a feeding hopper 4 and a powder weighing hopper 5. The powder weighing hopper is located directly below the feeding hopper. The powder adding device includes a powder adding hopper 6. The powder adding hopper is placed on the moving component. A driving mechanism is installed on the linear module. The driving mechanism is used to drive the moving component to move horizontally. After the moving component moves, a first working position and a second working position are respectively formed on the sliding table. When the moving component is located at the first working position, the powder adding hopper is located directly below the powder weighing hopper. When the moving component is located at the second working position, the powder adding hopper is located above the forming pressing cylinder.

[0029] As Figure 3 shown, the powder adding hopper includes a hopper body 7. The top of the hopper body is partially covered with a cover plate 19. A flexible first air inlet pipe 8 is provided at the inner end of the hopper body for pushing the powder material into the forming pressing cylinder. A weight sensor is arranged in the powder weighing hopper. When the material in the powder weighing hopper reaches the predetermined loading amount, the powder weighing hopper transfers the material to the powder adding hopper.

[0030] In this embodiment, a chute is opened on the end wall of the cover plate, and a protruding clamping edge is provided at the edge of the cover plate to facilitate clamping into the chute.

[0031] A pair of elastic sacs 9 are arranged in the hopper body. The elastic sac includes an elastic sheet 10 and an elastic membrane 11. The elastic sheet is connected to the inner wall of the hopper body through the elastic membrane, so that the elastic sheet, the elastic membrane and the inner wall of the hopper body form a closed elastic cavity. The elastic sheet protrudes outwards under the push of air pressure.

[0032] The inner end of the hopper body has an inclined surface 12. A long strip-shaped air outlet 13 is provided at the inner end of the hopper body. The air outlet is externally connected to the first air inlet pipe. The inner bottom surface of the hopper body is an inclined surface that slopes from one end close to the first air inlet pipe to the other end away from the first air inlet pipe.

[0033] A flexible second air inlet pipe 14 is installed on the hopper body. An extension pipe 18 extending into the hopper body is installed on the second air inlet pipe. A hollow fixed ball 15 is provided at the end of the extension pipe. Flexible branch pipes 16 are connected to both sides of the fixed ball. The end of the branch pipe communicates with the elastic sac. A pair of air pressure guiding plates 17 arranged in a proportional manner are installed on the extension pipe. The first air inlet pipe and the second air inlet pipe are externally connected to an air storage tank.

[0034] During the implementation of this embodiment, the second intake pipe and the first intake pipe are opened. The gas introduced through the second intake pipe causes the elastic bladder to bulge, and its protruding elastic piece forms a funnel-shaped channel. According to the Bernoulli effect, it is convenient for the airflow in the first intake pipe to orderly flow the powder outward into the molding pressing cylinder instead of scattering elsewhere.

[0035] Embodiment 2

[0036] The difference between this Embodiment 2 and Embodiment 1 is that a first electromagnetic control valve is installed on the first intake pipe, and a second electromagnetic control valve is installed on the second intake pipe. A gravity sensor is installed inside the powder adding hopper, and a control module is also provided inside the machine body. The gravity sensor is externally connected to the control module, and the control module is electrically connected to the first electromagnetic control valve and the second electromagnetic control valve. The control module of this embodiment generally adopts a computer system. A photoelectric sensor is provided on one side of the second working position for detecting whether the powder adding hopper is in the second working position.

[0037] During the implementation of this embodiment, when the gravity sensor in the powder adding hopper receives a predetermined weight signal, it transmits the weight signal to the control module. The control module controls the linear module to move the powder adding hopper from the first working position to the second working position. Then the photoelectric sensor detects that the powder adding hopper is in the second working position, controls the first solenoid valve and the second solenoid valve, and sequentially opens the second intake pipe and the first intake pipe. The gas introduced through the second intake pipe causes the elastic bladder to bulge, and its protruding elastic piece forms a funnel-shaped channel. The airflow in the first intake pipe orderly flows the powder outward into the molding pressing cylinder. When the gravity sensor in the powder adding hopper receives a reduced-to-predetermined weight signal, the second intake pipe and the first intake pipe are sequentially closed.

[0038] The above are only the preferred embodiments of the present invention, and thus do not limit the patent protection scope of the present invention. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention, directly or indirectly applied in other related technical fields, shall be similarly included in the protection scope of the present invention.
