[0004] In the aforementioned prior art, a motor drives the rotating base to rotate, and then a hydraulic cylinder moves the lower mold downwards. Multiple lower molds arranged in a circular array on the rotating base are pressed down sequentially to complete the powder metallurgy operation. However, due to prolonged use of the equipment, the motor may be damaged, thereby reducing the service life of the equipment and affecting its processing efficiency. Utility Model Content

[0029] 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.

[0030] Reference Figure 1-4The present invention provides a powder metallurgy forming equipment, including a box body 1, a fixed plate 2 fixedly connected to the middle of the inner wall of the box body 1, a rotating seat 3 rotatably connected to the top of the fixed plate 2, a lower mold 4 arranged in a circular array around the axis of the rotating seat 3 on the top of the rotating seat 3, an electric drive mechanism arranged on one side of the inner cavity of the box body 1 near the bottom of the fixed plate 2, a manual drive mechanism arranged on the other side of the inner cavity of the box body 1 near the bottom of the fixed plate 2, a box door 6 hinged to the surface of the box body 1, and a control panel 7 arranged on the surface of the box door 6.

[0031] First, the raw material is fed into the lower mold 4. Then, the electric drive mechanism is started through the control panel 7 on the door 6. Subsequently, the electric drive mechanism inside the equipment is started, causing the rotating seat 3 on the fixed plate 2 to rotate. Then, the hydraulic cylinder inside the equipment is started to drive the pressure plate and the upper mold to move down. The equipment then presses them to complete the powder metallurgy processing operation in the lower mold 4. After the equipment has been working for a long time, the electric drive mechanism can be disassembled, and then the rotating seat 3 can be rotated using the manual drive mechanism. This allows the equipment to be used normally or in an emergency, avoiding the problem of reduced processing efficiency due to damage to the servo motor 9.

[0032] The electric drive mechanism includes a servo motor 9 fixedly connected to the bottom of the fixed plate 2. One end of the servo motor 9 is fixedly connected to a connecting shaft 10. The end of the connecting shaft 10 is provided with a housing 5. The top of the housing 5 is rotatably connected to a rotating shaft 8. The top end of the rotating shaft 8 passes through the fixed plate 2 and is connected to the rotating seat 3. Connecting plates 13 are provided on opposite sides of the servo motor 9 and the housing 5. The top of the connecting plate 13 is fixedly connected to the bottom of the fixed plate 2.

[0033] By starting the servo motor 9 to drive the connecting shaft 10 to rotate, the connecting shaft 10 drives the second bevel gear 18 to rotate. The teeth on the rotating bevel gear 18 drive the teeth on the bevel gear 17 that meshes with it, causing the bevel gear 17 to rotate. Then, the rotating bevel gear 17 drives the rotating shaft 8 to rotate, which in turn drives the rotating seat 3 on the fixed plate 2 to rotate. Then, the hydraulic cylinder inside the equipment is activated to drive the pressure plate and the upper mold to move down. The equipment then presses them down, completing the powder metallurgy processing operation in the lower mold 4. This increases the practicality of the equipment and the processing efficiency of the equipment for powder metallurgy products.

[0034] The manual drive mechanism includes a sleeve 14 rotatably connected to the front surface of the box 5. A movable shaft 11 is slidably connected to the inner cavity of the sleeve 14. A handle 12 is fixedly connected to the end of the movable shaft 11. A limit rod 16 is fixedly connected to the outer contour of the movable shaft 11 near the inner wall of the sleeve 14. A limit groove 15 adapted to the movable shaft 14 is provided on the inner wall of the sleeve 14. A bevel gear 19 is fixedly connected to the end of the movable shaft 11 near the inner cavity of the box 5. The teeth on the outer contour of the bevel gear 19 mesh with the teeth on the outer contour of the bevel gear 18. Annular magnetic blocks 20 are fixedly connected to the inner walls of the box 5 near the connecting shaft 10 and the outer contour of the movable shaft 11. A fixing bolt is provided on the outer surface of the box 5 and is bolted to the annular magnetic block 20. A protective sleeve is fitted on the outer contour of the handle 12. An anti-slip groove is provided on the outer contour of the protective sleeve.

[0035] After the servo motor 9 was damaged, the staff disassembled it and pulled it to move the bevel gear 18 towards one of the annular magnetic blocks 20 inside the housing 5. The bevel gear 18 was then attracted and fixed. Next, the staff pushed the movable shaft 11 inside the sleeve 14 deeper into the housing 5, causing the bevel gear 19 on the movable shaft 11 to move towards the bevel gear 17, thus engaging the teeth of the bevel gear 19 with those of the bevel gear 17. The staff then turned the handle 12 to rotate the movable shaft 11, causing the limiting groove 15 on the movable shaft 11 to rotate. This caused the sleeve 14 to engage with the limiting rod 16 inside the sleeve 14 due to the limiting groove 15. This causes the sleeve 14 to rotate, allowing the movable shaft 11 to move and rotate. The rotation of the movable shaft 11 drives the bevel gear 19 to rotate, which in turn drives the rotating shaft 8 to rotate via the bevel gear 17. The rotating bevel gear 17 then drives the rotating shaft 8 to rotate, which in turn drives the rotating seat 3 on the fixed plate 2 to rotate. This activates the hydraulic cylinder inside the equipment, causing the pressure plate and upper mold to move downwards. The equipment then presses them down, completing the powder metallurgy processing operation within the lower mold 4. This allows the equipment to operate even if the servo motor 9 fails, ensuring that the processing efficiency is not reduced and further increasing the equipment's practicality. Furthermore, when rotating the handle 12, anti-slip sleeves and anti-slip grooves enhance its anti-slip effect. And if the annular magnetic block 20 is damaged or loses its magnetism, the fixing bolts on the box 5 can be removed, and the annular magnetic block 20 can be replaced.

[0036] Working principle: The servo motor 9 is started to drive the connecting shaft 10 to rotate. Then, the connecting shaft 10 drives the second bevel gear 18 to rotate. The teeth on the rotating bevel gear 18 drive the teeth on the bevel gear 17 that meshes with it, causing the bevel gear 17 to rotate. Then, the rotating bevel gear 17 drives the rotating shaft 8 to rotate. The rotating shaft 8 drives the rotating seat 3 on the fixed plate 2 to rotate. Then, the hydraulic cylinder in the equipment is started to drive the pressure plate and the upper mold to move down. Then the equipment presses them to complete the powder metallurgy processing operation in the lower mold 4.

[0037] After the servo motor 9 was damaged, the operator disassembled it and pulled it to move the bevel gear 18 towards one of the annular magnetic blocks 20 inside the housing 5. The bevel gear 18 was then attracted and secured. Next, the operator pushed the movable shaft 11 inside the sleeve 14 deeper into the housing 5, causing the bevel gear 19 on the movable shaft 11 to move towards the bevel gear 17, thus engaging the teeth of the bevel gear 19 with those of the bevel gear 17. The operator then turned the handle 12 to rotate the movable shaft 11, causing the limiting groove 15 on the movable shaft 11 to rotate, thereby... The sleeve 14 is engaged with the limiting rod 16 inside the sleeve 14 by the limiting groove 15, which causes the sleeve 14 to rotate. This allows the movable shaft 11 to move and rotate. When the movable shaft 11 rotates, it drives the bevel gear 19 to rotate, which in turn drives the rotating shaft 8 to rotate through the bevel gear 17. Then, the rotating bevel gear 17 drives the rotating shaft 8 to rotate, which in turn drives the rotating seat 3 on the fixed plate 2 to rotate. Then, the hydraulic cylinder inside the equipment is activated to move the pressure plate and the upper mold downward. The equipment then presses them down to complete the powder metallurgy processing operation in the lower mold 4.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
