Description

Technical Field

[0001] This utility model relates to the field of powder metallurgy technology, specifically to a quantitative conveying device for metal powder in a powder metallurgy automotive parts processing and arranging machine. Background Technology

[0002] Powder metallurgy can produce complex parts with high precision and high performance, and has the advantages of high material utilization, low energy consumption and environmental protection. It is used for various automotive parts, gears, sprockets, valves, bearings, bearing sleeves and other components, as well as parts of various machining tools, turning heads, drills and so on.

[0003] Powder metallurgy is a technology that uses powder to form various products through high-temperature heating. The main steps in powder metallurgy for manufacturing automotive parts are as follows: 1. Raw material preparation: The raw materials are first made into powder particles, mixed in a certain proportion to form a raw material, and then fed into a mold for pressing and shaping; 2. Press molding: The uniformly mixed raw material is placed in the mold and pressed to form a preform. The initial preform is relatively fragile and is carefully placed to await sintering; 3. Sintering: The preform is sent into a sintering furnace with a strictly controlled environment. The sintering temperature is set below the melting point of the main raw materials to help the materials diffuse and fuse, thereby strengthening the material structure and forming specific mechanical properties.

[0004] Powder metallurgy automotive parts require the mixed powder to be conveyed into the forming hole for forming. Currently, powder metallurgy powder conveying is carried out by feeding pipe and weighing device. During the quantitative feeding process, dust will be generated when the powder flows. Due to the characteristics of metal powder, it is easy to cause blockage and unevenness of the feed port during the conveying process, resulting in inaccurate quantitative feeding and affecting the performance of the final product. Utility Model Content

[0005] The purpose of this invention is to provide a quantitative conveying device for metal powder in a powder metallurgy automotive parts processing and arranging machine, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A metal powder quantitative conveying device for a powder metallurgy automotive parts processing and arranging machine includes a metal powder conveying device for continuous conveying of metallurgical powder and a quantitative discharge device located at the discharge port end of the metal powder conveying device. A powder pressing and molding component is provided on the side of the quantitative discharge device away from the metal powder conveying device.

[0008] The quantitative discharging device includes a quantitative discharging drive assembly, a bushing, a shaft, and quantitative actuating blades. The shaft is vertically located inside the bushing, and its bottom is connected to the bottom of the bushing via a bearing. The top of the shaft extends through the top of the bushing and sits above it. A fixed cylinder is integrally fixedly sleeved on the outer circumferential wall of the shaft inside the bushing. The quantitative actuating blades are semi-circular in structure, and there are six quantitative actuating blades in total. The six quantitative actuating blades are evenly distributed on the outer circumferential wall of the fixed cylinder inside the bushing, and the outer wall of the end of each quantitative actuating blade away from the fixed cylinder is in contact with the bushing.

[0009] As a preferred embodiment of this utility model, an arc-shaped structure for preventing powder adhesion and accumulation is provided on the inner wall of the connection between each of the quantitative actuating blades and the fixed cylinder rod.

[0010] As a preferred embodiment of this utility model, the metal powder conveying device includes a conveying auger, with a powder inlet at the top of the end of the conveying auger near the drive motor, and the end of the conveying auger away from the drive motor connected to the bushing via a connecting cylinder.

[0011] As a preferred embodiment of this utility model, the powder pressing and molding assembly includes a pressing platform, a pressing groove is provided on the pressing platform, a metering powder box is provided on the pressing platform located on one side of the pressing groove, a powder inlet hole is provided through the bottom of the metering powder box, and the top of the metering powder box is connected through to the outer circumferential wall of the end of the bushing away from the conveying auger.

[0012] As a preferred embodiment of this utility model, the quantitative discharge drive assembly includes a drive solenoid valve, which is fixedly located on the outer wall of the top of the bushing, and the output shaft of the drive solenoid valve is connected to the shaft at the top of the bushing via a coupling.

[0013] In a preferred embodiment of this invention, the drive solenoid valve is connected to the control device via a wire.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In response to the problems raised in the background art, this application sets up a quantitative discharge device on the basis of continuous powder conveying of the metal powder conveying device. The quantitative discharge device discharges a quantitative amount of metal powder to ensure the accuracy of the discharge and the performance of the final product.

[0016] By driving the solenoid valve to drive the shaft, the metering blades on the outer circumferential wall of the fixed cylinder on the shaft are driven to meter the material, which is accurate and will not cause material blockage.

[0017] After being metered out by a metering blade, the metal powder enters the metering powder box. The displacement of the metering powder box drives the metal powder into the pressing tank for powder pressing and shaping.

[0018] The solution addresses the problems of dust generation and easy blockage of the feed pipe opening during the current powder quantitative conveying process, which involves feeding and conveying powder using a feed pipe and weighing device, leading to inaccurate quantitative conveying and affecting the performance of the final product.

[0025] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the embodiments of this utility model.

[0026] Example

[0027] All devices in this application adopt conventional models in the prior art, and the control method is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field, so this application will not explain it in detail.

[0028] Please see Figure 1-5This utility model provides a technical solution: a quantitative conveying device for metal powder in a powder metallurgy automotive parts processing and arranging machine, comprising a metal powder conveying device 1 for continuous conveying of metallurgical powder and a quantitative discharge device 2 located at the discharge end of the metal powder conveying device 1. A powder pressing and molding assembly is provided on the side of the quantitative discharge device 2 away from the metal powder conveying device 1. The metal powder conveying device 1 includes a conveying auger 11, with a powder inlet 12 opened at the top of the end of the conveying auger 11 near the drive motor. The end of the conveying auger 11 away from the drive motor is connected to a bushing 22 through a connecting cylinder 4. The powder pressing and molding assembly includes a pressing platform 5, with a pressing groove 51 provided on the pressing platform 5. A quantitative powder box 52 is provided on the pressing platform 5 on one side of the pressing groove 51. A powder inlet hole 521 is provided through the bottom of the quantitative powder box 52. The top of the quantitative powder box 52 is connected through to the outer circumferential wall of the end of the bushing 22 away from the conveying auger 11.

[0029] It should be noted that in this embodiment, the metal powder is continuously conveyed by the conveying auger 11, and the conveying auger 11 has good adaptability and accuracy during the conveying process.

[0030] Furthermore, when the screw shaft rotates, the metal powder material does not rotate with the screw blades due to its own gravity and the friction between the casing and the material. Instead, it moves forward under the push of the screw blades, continuously conveying the powder material. No dust or blockage will occur during the conveying process.

[0031] Furthermore, the top of the quantitative powder box 52 is connected to the outer circumferential wall of the end of the bushing 22 away from the conveying auger 11. When the quantitative powder enters the quantitative powder box 52, the driving device pushes the quantitative powder box 52 to a certain position. The displacement of the quantitative powder box 52 simultaneously drives the quantitative metal powder inside through the pressing groove 51. The metal powder enters the pressing groove 51 through the powder inlet hole 521 at the bottom of the quantitative powder box 52 and is pressed and formed. The structure is simple, and dust is generated during the feeding process. Quantitative feeding ensures product performance.

[0032] Please see Figure 1 , 23 and 4, the quantitative discharging device 2 includes a quantitative discharging drive assembly, a bushing 22, a shaft 23, and quantitative actuating blades 24. The shaft 23 is vertically located inside the bushing 22. The bottom of the shaft 23 is connected to the bottom of the bushing 22 via a bearing. The top of the shaft 23 extends through the top of the bushing 22 and above it. A fixed cylinder 25 is integrally fixedly sleeved on the outer circumferential wall of the shaft 23 inside the bushing 22. The quantitative actuating blades 24 are semi-circular in structure, and there are six quantitative actuating blades 24 in total. The six quantitative actuating blades 24 are evenly distributed on the bushing. On the outer circumferential wall of the fixed cylinder rod 25 inside the sleeve 22, the outer wall of each metering actuating blade 24 away from the fixed cylinder rod 25 is in contact with the bushing 22; an anti-powder adhesion and accumulation arc-shaped structure 26 is provided on the inner wall of the connection between each metering actuating blade 24 and the fixed cylinder rod 25; the metering discharge drive assembly includes a drive solenoid valve 211, which is fixedly located on the top outer wall of the bushing 22, and the output shaft of the drive solenoid valve 211 is connected to the shaft rod 23 at the top of the bushing 22 through a coupling; the drive solenoid valve 211 is connected to the control device through a wire.

[0033] It should be noted that in this embodiment, the solenoid valve 211 drives the shaft 23 to drive the metering blade 24 on the outer circumferential wall of the fixed cylinder 25 on the shaft 23 to meter the material, which ensures accurate material discharge and prevents material blockage.

[0034] Furthermore, after the metal powder is quantitatively discharged by the quantitative actuating blade 24, it enters the quantitative powder box 52. The displacement of the quantitative powder box 52 drives the metal powder into the pressing tank 51 for powder pressing and molding. This solves the problem that the existing quantitative powder conveying is carried out by feeding pipe and weighing device, which causes dust and easy blockage of the feeding pipe opening, resulting in inaccurate quantitative conveying and affecting the performance of the final product.

[0035] Furthermore, the metering blades 24 precisely control the discharge of metal powder. They move the material as the fixed cylinder rod 25 rotates. Due to the design and arrangement of the blades, accurate metering can be achieved. The metal powder released by the metering blades 24 enters the metering powder box 52. Then, through the displacement of the box, the metal powder is pushed into the pressing groove 51 for the next powder pressing and molding process. This not only improves the quality and consistency of the product, but may also improve production efficiency and reduce maintenance costs.

[0036] The working process of this utility model:

[0037] In use, the conveying auger 11 is started, and the metal powder is continuously conveyed through the conveying auger 11. The conveyed material enters the front side of the bushing 22 through the connecting cylinder 4. The controller starts the drive solenoid valve 211 to work. The drive solenoid valve 211 drives the drive shaft 23 to rotate. The shaft 23 drives the quantitative agitator blade 24 on the outer circumferential wall of the fixed cylinder 25 on the shaft 23 to perform quantitative discharge agitation. The quantitative material enters the quantitative powder box 52. The displacement of the quantitative powder box 52 drives the metal powder into the pressing tank 51 for powder pressing and molding. This solves the problem that the existing quantitative powder conveying is carried out by feeding pipe and weighing device, which causes dust and easy blockage of the feeding pipe inlet, resulting in inaccurate quantitative conveying and affecting the performance of the final product.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
