Detailed Implementation

[0021] 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.

[0022] Please see Figure 1-4 An electro-hydraulic servo-driven fully automatic powder forming press includes a base plate 1, a support plate 2 and a top plate 3 on the upper side of the base plate 1, support rods 4 fixedly connected at the four corners between the base plate 1, support plate 2 and top plate 3, a hopper 5 through and fixedly connected to the upper end surface of the top plate 3, and a forming mechanism between the support plate 2 and the top plate 3.

[0023] The forming mechanism includes a turntable 6 rotatably connected to the upper end face of the support plate 2. The upper end face of the turntable 6 abuts against the outlet of the hopper 5. Multiple circumferentially distributed forming holes 8 are opened through the outer wall of the turntable 6. A servo motor 7 with its output end fixedly connected to the turntable 6 is installed on the lower end face of the support plate 2. A discharge port 9 is opened through the outer wall of the support plate 2. An electro-hydraulic actuator 10 is installed on the upper end face of the top plate 3. The output end of the electro-hydraulic actuator 10 extends to the bottom of the top plate 3 and is fixedly connected to a mounting plate 11. A pressure mold 12 and an ejector plate 13 are fixedly connected to the lower end face of the mounting plate 11 through a connecting rod.

[0024] In this embodiment: the powder material in the hopper 5 falls into the forming hole 8 of the turntable 6. The servo motor 7 drives the turntable 6 to rotate, so that the forming hole 8 is accurately positioned to the pressing station. The electro-hydraulic actuator 10 pushes the mounting plate 11 downward, driving the pressing mold 12 to perform high-pressure pressing on the powder. After pressing is completed, the electro-hydraulic actuator 10 returns, the turntable 6 rotates to send the molded part to the ejection station, and at the same time, the new forming hole 8 enters the pressing station, forming a continuous operation cycle. When the electro-hydraulic actuator 10 presses down again, the pressing mold 12 performs pressing at the new station, and the ejector plate 13 simultaneously ejects the previously molded part to the discharge port 9, completing the automatic unloading. This utility model uses the electro-hydraulic actuator 10 for direct drive, which has the characteristics of low energy consumption, fast response and high control accuracy. The turntable 6, together with multiple forming holes 8, realizes continuous cycle operation, which significantly improves production efficiency. The integrated linkage structure of the pressing mold 12 and the ejector plate 13 realizes the automation of pressing-ejection and reduces manual intervention.

[0025] As a technical optimization of this utility model, a belt conveyor 15 is provided on the lower end face of the support plate 2 below the discharge port 9. Slide rods 16 are fixedly connected to the four corners of the lower end face of the belt conveyor 15. Four sleeves 17 that are slidably connected to the slide rods 16 are fixedly connected to the upper end face of the base plate 1. Springs 18 located between the belt conveyor 15 and the base plate 1 are sleeved on the outside of the multiple sleeves 17. Two pressure rods 14 are fixedly connected to the lower end face of the mounting plate 11. Two connecting plates 19 located below the pressure rods 14 are fixedly connected to the outer wall of the belt conveyor 15.

[0026] In this embodiment: when the mounting plate 11 moves downward, it drives the two pressure rods 14 to move downward. When the ejector plate 13 drives the molded part to contact the belt conveyor 15, the pressure rods 14 are in contact with the two connecting plates 19 on the outer wall of the belt conveyor 15. This drives the molded part to be discharged, and the belt conveyor 15 moves downward accordingly, thereby ejecting the molded part onto the belt conveyor 15. The belt conveyor 15 is started to transport the molded part to the next process. The spring 18 can keep the belt conveyor 15 close to the discharge port 9 to prevent the molded part from falling directly onto the belt conveyor 15 and being damaged.

[0027] As a technical optimization of this utility model, the height of the mold 12 is higher than the height of the ejector plate 13.

[0028] In this embodiment, by making the height of the mold 12 higher than the height of the ejector plate 13, it is easier to discharge the material.

[0029] As a technical optimization of this utility model, a rubber pad is provided on the lower end surface of the ejector plate 13.

[0030] In this embodiment, a rubber pad is provided on the lower end face of the ejector plate 13 to prevent damage to the molded part.

[0031] As a technical optimization of this utility model, a controller is provided on the outer wall of one of the support rods 4, and the servo motor 7, electro-hydraulic actuator 10 and belt conveyor 15 are all electrically connected to the controller.

[0032] In this embodiment, the controller facilitates the normal operation of the servo motor 7, the electro-hydraulic actuator 10, and the belt conveyor 15.

[0033] As a technical optimization of this utility model, the inner wall of the forming hole 8 is provided with a wear-resistant ceramic coating.

[0034] In this embodiment, by providing a wear-resistant ceramic coating on the inner wall of the forming hole 8, the service life of the forming hole 8 can be improved.

[0035] The working principle and usage process of this utility model are as follows: Powder material in hopper 5 falls into the forming hole 8 of turntable 6. Servo motor 7 drives turntable 6 to rotate, so that the forming hole 8 is accurately positioned to the pressing station. Electro-hydraulic actuator 10 pushes mounting plate 11 downward, driving die 12 to press the powder under high pressure. After pressing, electro-hydraulic actuator 10 returns, turntable 6 rotates to send the molded part to the ejection station, and at the same time, a new forming hole 8 enters the pressing station, forming a continuous operation cycle. When electro-hydraulic actuator 10 presses down again, die 12 performs pressing at the new station, and ejection plate 13 simultaneously ejects the previously molded part to discharge port 9, completing automatic unloading. This utility model uses electro-hydraulic actuator 10 for direct drive, which has the characteristics of low energy consumption, fast response and high control accuracy. Turntable 6, together with multiple forming holes 8, realizes continuous cycle operation, significantly improving production efficiency. The integrated linkage structure of die 12 and ejection plate 13 realizes the automation of pressing-ejection, reducing manual intervention.
