Description

Technical Field

[0001] This utility model relates to the field of powder metallurgy, specifically to a powder metallurgy screw pressing device that facilitates material handling. Background Technology

[0002] Powder metallurgy is a process technology that uses metal powder or a mixture of metal powder and non-metal powder as raw materials, and then shapes and sinters to manufacture metal materials, composite materials, and various types of products. Powder metallurgy screw pressing equipment is an important piece of equipment used in powder metallurgy to produce screw-type parts. The working principle of powder metallurgy screw pressing equipment is to load metal powder into a mold, and then apply pressure through a pressing system to compact the powder into a screw blank of a predetermined shape. During the pressing process, the gaps between powder particles are filled, the contact area between particles increases, and a blank with a certain density and strength is formed. After pressing, the screw blank is removed from the mold through a demolding system for subsequent processing and machining.

[0003] A search revealed a powder metallurgy pressing device (CN219093633U). Specifically, this device includes a collecting hopper fixedly connected to the front of a base via a connecting frame. A mesh plate is fixedly connected to the top of the collecting hopper. A lead screw is movably connected to the inside of the collecting hopper. A brush is slidably connected to the inner side of the collecting hopper, and the brush is sleeved on the outer side of the lead screw. A pipe connects to the bottom of the collecting hopper. A collecting box is located below the collecting hopper on the front side of the base. One end of the pipe connects to the top of the collecting box. When excess metal powder is fed into the collecting hopper via a conveying box, the metal powder enters the collecting box through the pipe, thus collecting and recycling the excess metal powder and preventing its accumulation and waste. The lead screw drives the brush to move, thereby brushing away the metal powder adhering to the bottom of the metal powder parts placed on top of the mesh plate. This eliminates the need for manual cleaning by workers, reducing their labor intensity.

[0004] In the operation of existing powder metallurgy screw pressing equipment, timely material handling is required during batch production. However, the existing equipment lacks convenient material handling capabilities, necessitating manual material handling. This is not only time-consuming and labor-intensive but also easily affects production efficiency. Furthermore, the powder metallurgy screw pressing equipment in the aforementioned comparative case also lacks convenient material handling capabilities. Over long-term use, manual material handling will introduce errors, leading to product damage or waste of excess powder.

[0005] Therefore, it is necessary to invent a powder metallurgy screw pressing device that facilitates material handling to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a powder metallurgy screw pressing device that facilitates material handling. Through a metallurgical pressing die opening, a pusher plate, an extension frame, a second telescopic cylinder, a material handling plate, and a material handling box, the device achieves convenient material handling. This design realizes seamless integration of pressing and material handling, improving production efficiency. Furthermore, the telescopic clamping of the second telescopic cylinder and the material handling plate ensures the accuracy and stability of material handling. Combined with the material handling box's filtration and isolation, excess powder and product can be effectively separated, facilitating subsequent processing and recycling. With long-term use, this automated and intelligent approach reduces... This technology eliminates the need for manual intervention, improves the efficiency and accuracy of material handling, and reduces production costs. It addresses the problem in existing powder metallurgy screw pressing equipment where timely material handling is crucial during mass production. Since the equipment lacks convenient material handling capabilities, manual handling is often necessary, which is time-consuming, labor-intensive, and can negatively impact production efficiency. Furthermore, the powder metallurgy screw pressing equipment in the aforementioned comparative case also lacks convenient material handling capabilities. Over time, this manual handling can lead to errors, resulting in product damage or waste of excess powder.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a powder metallurgy screw pressing device that facilitates material handling, comprising a powder metallurgy pressing machine body, which is the main body for performing powder metallurgy.

[0008] A metallurgical pressing mold opening is set on the surface of the powder metallurgy pressing machine body for filling metallurgical powder, and a telescopic ejector plate is set inside the metallurgical pressing mold opening. A pressing slide rod is fixedly installed on the top of the powder metallurgy pressing machine body, and a pressing plate is fixedly installed on the top of the pressing slide rod.

[0009] A fixed chute is set above the powder metallurgy pressing machine body and is used to movably connect a fixed slider. A pusher plate is fixedly installed on the outside of the fixed slider. Extension frames are set on both sides of the pusher plate. A second telescopic cylinder is fixedly installed on the outside of the extension frames. A material picking plate is fixedly installed at the front end of the second telescopic cylinder. An infrared sensor is set inside the material picking plate.

[0010] The material collection box is located at the front of the powder metallurgy pressing machine and is used to collect powder metallurgy products. Both sides of the inside of the material collection box are provided with docking grooves. A docking slider is movably connected inside the docking groove, and a material collection filter screen is fixedly installed on the outside of the docking slider.

[0011] Preferably, a fixing bolt passes through the exterior of the powder metallurgy pressing machine body, and one end of the fixing bolt is movably connected to an outer transparent protective plate.

[0012] Preferably, a limiting ring is provided on the outside of the pressing slide bar, a damping telescopic spring is fixedly installed above the limiting ring, and a buffer ring is fixedly installed on the top of the damping telescopic spring.

[0013] Preferably, a first telescopic cylinder is provided above the pressing plate, a metallurgical plate is fixedly installed at the bottom of the first telescopic cylinder, a servo motor is provided inside the metallurgical plate, and a pressing screw is fixedly installed at the output end of the servo motor.

[0014] Preferably, a hydraulic cylinder is provided on the back of the powder metallurgy pressing machine body, a push plate is fixedly installed at the front end of the hydraulic cylinder, and a push plate is fixedly connected to the outside of the push plate.

[0015] Preferably, the material receiving filter screen is slidably connected to the material receiving box, and the docking slider is used in conjunction with the docking groove.

[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0017] 1. This utility model is equipped with a metallurgical pressing mold opening, a pusher plate, an extension frame, a second telescopic cylinder, a take-up plate, and a take-up box. When using this powder metallurgy screw pressing equipment, the powder enters the metallurgical pressing mold opening and is pressed by the screw. After being pressed, it is pushed out by the telescopic ejector plate. At this time, the pusher plate slides on the surface of the powder metallurgy pressing machine body. The take-up plates on both sides of the pusher plate will sense the position of the powder metallurgy finished product through infrared sensors. After positioning, the second telescopic cylinder and the take-up plate clamp the product. Then, the pusher plate continues to push the metallurgical powder on the surface of the powder metallurgy pressing machine body and the product together into the take-up box. At the same time, a take-up filter is also provided inside the take-up box. The mesh not only separates the product from the metallurgical powder, but also facilitates quick extraction of the powder metallurgy finished product by external personnel. This combination gives the powder metallurgy screw pressing equipment easy material handling capabilities. This design achieves seamless integration of pressing and material handling, improving production efficiency. Furthermore, the telescopic clamping of the second telescopic cylinder and the material handling plate ensures the accuracy and stability of material handling. Combined with the material handling box filter isolation, excess powder and product can be effectively separated, facilitating subsequent processing and recycling. With long-term use, this automation and intelligent approach reduces manual intervention, improves material handling efficiency and accuracy, and lowers production costs.

[0018] 2. This utility model is equipped with a pressing slide bar, a limiting ring, a damping telescopic spring, a buffer ring, a pressing plate, a first telescopic cylinder, and a metallurgical plate. When the first telescopic cylinder drives the metallurgical plate to descend and the pressing screw presses the metallurgical powder inside the metallurgical pressing die, the damping telescopic spring and buffer ring located outside the pressing slide bar will extend and retract with the descent of the metallurgical plate to buffer the impact. This causes the buffer ring to contact the limiting ring. This combination design can effectively absorb the impact force generated when the metallurgical plate descends, reduce vibration and noise during the pressing process, and ensure the stability of the metallurgical plate during the pressing process through the contact of the buffer ring and the cooperation of the limiting ring. This reduces the deviation caused by vibration, further improves the pressing accuracy of the metallurgical screw, and ensures product quality. Attached Figure Description

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] This utility model provides, for example Figure 1-5 The invention relates to a powder metallurgy screw pressing device that facilitates material handling, comprising a powder metallurgy pressing machine body 1, which is the main body for performing powder metallurgy.

[0029] Metallurgical pressing mold opening 4 is set on the surface of powder metallurgy pressing machine body 1 for filling metallurgical powder, and a telescopic ejector plate 5 is set inside the metallurgical pressing mold opening 4. A pressing slide rod 6 is fixedly installed on the top of the powder metallurgy pressing machine body 1, and a pressing plate 10 is fixedly installed on the top of the pressing slide rod 6.

[0030] A fixed chute 15 is set above the powder metallurgy pressing machine body 1 and is used to movably connect the fixed slider 16. A push plate 17 is fixedly installed on the outside of the fixed slider 16. Extension frames 18 are set on both sides of the push plate 17. A second telescopic cylinder 19 is fixedly installed on the outside of the extension frame 18. A material picking plate 20 is fixedly installed at the front end of the second telescopic cylinder 19. An infrared sensor 21 is set inside the material picking plate 20.

[0031] The material collection box 24 is located in front of the powder metallurgy pressing machine body 1 and is used to collect powder metallurgy products. Both sides of the material collection box 24 are provided with docking grooves 25. The docking grooves 25 are movably connected to the docking sliders 26. The material collection filter 27 is fixedly installed on the outside of the docking sliders 26. The material collection box 24 is also provided with a material collection filter 27, which can not only isolate the product and the metallurgical powder, but also facilitate the quick extraction of the powder metallurgy products by external personnel.

[0032] like Figure 1 , Figure 2 and Figure 3As shown, a fixing bolt 2 passes through the exterior of the powder metallurgy pressing machine body 1. One end of the fixing bolt 2 is movably connected to an outer transparent protective plate 3. The outer transparent protective plate 3 provides a certain degree of protection for the internal components of the powder metallurgy pressing machine body 1. A limiting ring 7 is provided on the exterior of the pressing slide rod 6. A damping telescopic spring 8 is fixedly installed above the limiting ring 7. A buffer ring 9 is fixedly installed on the top of the damping telescopic spring 8. The damping telescopic spring 8 and the buffer ring 9, which are located outside the pressing slide rod 6, will expand and contract as the metallurgical plate 12 descends, causing the buffer ring 9 to contact the metallurgical plate 12. The combination design of the limiting ring 7 can effectively absorb the impact force generated when the metallurgical plate 12 descends, reducing vibration and noise during the pressing process. A first telescopic cylinder 11 is set above the pressing plate 10, and the metallurgical plate 12 is fixedly installed at the bottom of the first telescopic cylinder 11. A servo motor 13 is set inside the metallurgical plate 12, and a pressing screw 14 is fixedly installed at the output end of the servo motor 13. The first telescopic cylinder 11 drives the metallurgical plate 12 to descend, while the servo motor 13 drives the pressing screw 14 to rotate, so that the pressing screw 14 steadily completes the pressing work of the metallurgical powder.

[0033] like Figure 1 , Figure 4 and Figure 5 As shown, a hydraulic cylinder 22 is provided on the back of the powder metallurgy pressing machine body 1. A push plate 23 is fixedly installed at the front end of the hydraulic cylinder 22. A push plate 17 is fixedly connected to the outside of the push plate 23. By extending and retracting the hydraulic cylinder 22, the push plate 23 drives the push plate 17 to slide back and forth on the powder metallurgy pressing machine body 1. The material pick-up filter 27 is slidably connected to the material pick-up box 24. The docking slider 26 works in conjunction with the docking groove 25. The material pick-up filter 27 is provided inside the material pick-up box 24. The docking slider 26 facilitates the quick extraction of the powder metallurgy finished product by external personnel.

[0034] The working principle of this practical application is as follows: First, connect the external power supply and inject an appropriate amount of metallurgical powder into the metallurgical pressing mold opening 4 of the powder metallurgy pressing machine body 1. Then, turn on the servo motor 13 to drive the pressing screw 14 to rotate. Next, turn on the first telescopic cylinder 11 to drive the metallurgical plate 12 and the pressing screw 14 to descend slowly. At this time, the damping telescopic spring 8 and the buffer ring 9 located outside the pressing slide 6 will extend and retract as the metallurgical plate 12 descends, causing the buffer ring 9 to contact the limiting ring 7. This combination design can effectively absorb the impact force generated when the metallurgical plate 12 descends, reducing the pressing pressure. The vibration and noise during the process are mitigated by the contact of the buffer ring 9 and the cooperation of the limiting ring 7, which ensures the stability of the metallurgical plate 12 during the pressing process, reduces deviations caused by vibration, further improves the pressing accuracy of the metallurgical screw, and ensures product quality. Subsequently, the powder enters the metallurgical pressing mold opening 4 and is pressed by the screw. After being pressed, it is ejected by the telescopic ejector plate 5. Then, the switch of the hydraulic cylinder 22 is turned on. Through the extension and retraction of the hydraulic cylinder 22, the push plate 23 drives the pusher plate 17 to slide back and forth on the powder metallurgy pressing machine body 1. Then, the picking plates 20 on both sides of the pusher plate 17 will sense the position of the current powder metallurgy product through the infrared sensor 21. After positioning, the second telescopic cylinder 19 and the material-receiving plate 20 clamp the product. Then, the pusher plate 17 pushes the metallurgical powder and product from the surface of the powder metallurgy pressing machine body 1 into the material-receiving box 24. The material-receiving box 24 also contains a material-receiving filter 27, which not only isolates the product from the metallurgical powder but also facilitates quick removal of the powder-metallurgically processed product by external personnel. This design gives the powder metallurgy screw pressing equipment easy material-receiving capabilities, achieving seamless integration of pressing and material-receiving, improving production efficiency. Furthermore, the telescopic clamping of the second telescopic cylinder 19 and the material-receiving plate 20 ensures the accuracy and stability of material-receiving. With the addition of the material collection box 24 for filtration and isolation, excess powder and product can be effectively separated, facilitating subsequent processing and recycling. After this operation is completed, metallurgical powder can be fed into the metallurgical pressing mold port 4 to continue the powder metallurgy screw pressing operation. The pressed product can be uniformly removed by pulling out the material collection filter screen 27. Finally, after completing the installation and use of all powder metallurgy screw pressing equipment according to the above operations, turn off the switches of the first telescopic cylinder 11 and the second telescopic cylinder 19, and turn off the switch of the hydraulic cylinder 22. If it is not used for a long time, simply disconnect the external power supply. In this way, the use process of the powder metallurgy screw pressing equipment that facilitates material collection is completed.
