Description

Technical Field

[0001] This application relates to the field of powder metallurgy machinery, and particularly to an automatic mechanical press. Background Art

[0002] Powder metallurgy is a process technology for producing metal powders or using metal powders (or mixtures of metal powders and non-metal powders) as raw materials, and manufacturing metal materials, composite materials, and various types of products through shaping and sintering. The powder metallurgy method has similarities with the production of ceramics and both belong to powder sintering technology. Therefore, a series of new powder metallurgy technologies can also be used in the preparation of ceramic materials. Due to the advantages of powder metallurgy technology, it has become the key to solving new material problems and plays a crucial role in the development of new materials. Powder metallurgy technology is widely used in the manufacture of various precision parts. Currently, when the existing automatic mechanical press presses products with relatively thin wall thicknesses, material shortage problems are likely to occur during the powder loading process, affecting product quality.

[0003] To address the above problems, the prior art usually adopts methods such as increasing the number of pressing times or manually filling the powder to solve the material shortage problem. However, these methods are inefficient and cannot ensure the uniformity of filling and the consistency of products. Moreover, increasing the number of pressing times will lead to an extended production cycle and increased costs, while manual filling has problems such as inconvenient operation and low precision. Summary of the Utility Model

[0008] By adopting the above technical solutions, through the setting of the vibrator, when filling the powder into the lower mold, the vibrator can drive the lower mold to vibrate, so that the powder material can be automatically filled. Through the setting of the feeder and the powder distributor, when the feeder slides above the lower mold, the powder material is evenly distributed from the powder distributor into the cavity of the lower mold. Combining with the use of the vibrator, the efficiency and uniformity of powder filling are further improved.

Moreover, the vibration sensor can monitor the vibration, transmit the monitoring data to the controller, and the controller adjusts the vibration frequency and amplitude of the vibration cylinder in real time according to the monitoring data to achieve more precise powder filling.

[0013] Optionally, a feed pipe is fixedly connected to the top of the feeder.

[0014] By adopting the above technical solution, the powder material enters the feeder from the feed pipe.

[0015] Optionally, a plurality of powder outlets are formed in the powder distributor.

[0017] Optionally, an inclined powder screening plate is fixedly installed inside the feeder.

[0018] By adopting the above technical solution, the powder screening plate can screen out larger particles in the powder material, enabling the powder material entering the die to have uniform particle size and improving the product quality.

[0019] Optionally, a first powder return pipe is fixedly connected to one side of the feeder near the lower end of the powder screening plate.

[0020] By adopting the above technical solution, the screened powder material with larger particles can be discharged from the first powder return pipe.

[0021] Optionally, a discharge hopper is fixedly installed at the discharge end of the machine base. A plurality of leakage holes are formed in the top surface of the discharge hopper, and a second powder return pipe is fixedly connected to the bottom of the discharge hopper.

[0022] By adopting the above technical solution, when the formed product is discharged from the discharge hopper, the powder material carried by the product will enter the interior of the discharge hopper along the leakage holes and return to the powder container through the second powder return pipe for reuse.

[0023] In summary, the present application has the following beneficial effects:

[0024] 1. By setting the vibrator in the present application, when filling the powder material into the lower mold, the vibration cylinder can be controlled by the controller to generate vibration, so that the vibration cylinder drives the lower mold to vibrate, thereby enabling the powder material to be automatically filled.
