Description

Technical Field

[0001] This utility model relates to the field of plate punching technology, and in particular to a plate punching device for processing powder metallurgy machine accessory molds. Background Technology

[0002] Powder metallurgy is a technology that uses metal powders (or mixed powders) as raw materials and prepares materials or products through two core steps: forming (such as molding and isostatic pressing) and sintering (heating to a temperature below the melting point to bond particles). The powder metallurgy process requires a powder metallurgy machine, and the processing requires the use of component molds to assist in forming. During the processing of component molds, punching is necessary on the sheet metal.

[0003] Existing sheet metal punching equipment typically requires manual loading and unloading. During punching, the sheet metal needs to be manually placed in or removed, which is inefficient. When there are many sheet metals, continuous loading and unloading can cause manual fatigue, thus affecting the efficiency of the punching process. At the same time, the manual loading and unloading method poses significant safety hazards and is prone to injury. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a punching device for processing plate parts in powder metallurgy machine parts molds.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A punching device for processing plate parts in powder metallurgy machine parts molds includes a conveying assembly. The conveying assembly includes a base, and a protective cover is fixedly installed on the top outer wall of the base by bolts. Several sets of support frames are installed on the top of the base. A drive motor is installed on one side of the support frame. The output end of the drive motor is connected to a transmission shaft. One end of the transmission shaft is rotatably inserted through the support frame and a conveying wheel is installed on the other end of the transmission shaft. Electric telescopic rods are symmetrically installed on both sides of the protective cover. The telescopic end of one side of the electric telescopic rod is slidably connected to the inside of the protective cover. A clamping frame is provided at the end of the electric telescopic rod. A punching assembly for punching is provided on one side of the protective cover, and a buffer assembly for protecting the plate is provided on one side of the clamping frame.

[0007] As a further embodiment of this utility model: the punching assembly includes a hydraulic telescopic rod, which is installed on one side of the protective cover. The telescopic end of the hydraulic telescopic rod is slidably connected to the inside of the protective cover. A connecting block is installed at the end of the hydraulic telescopic rod, and a hydraulic lifting rod is installed at the bottom of the connecting block. A punching mold is detachably installed at the bottom of the hydraulic lifting rod.

[0008] As a further embodiment of this utility model: the buffer assembly includes a spring, and several sets of springs are provided and respectively installed on one side of the clamping frame. A pressure plate is installed at the end of the spring. The clamping frame has two sets of guide holes, through which guide rods are slidably installed. One end of the guide rod is fixed to the pressure plate.

[0009] As a further embodiment of this utility model: an electric lifting rod is installed on the inner wall of the top of the protective cover, a mounting base is installed at the bottom of the electric lifting rod, a rotary motor is installed on one side of the mounting base, a rotary shaft is connected to the output end of the rotary motor, one end of the rotary shaft is rotatably inserted through the mounting base, and a rotating roller is installed at the other end of the rotary shaft.

[0022] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.

[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0024] Example 1

[0025] A punching device for plate parts in powder metallurgy machine parts mold processing, such as Figure 1-4 As shown, the system includes a conveying assembly, which includes a base 1. A protective cover 8 is fixedly installed on the top outer wall of the base 1 by bolts. Several sets of support frames 5 are installed on the top of the base 1. A drive motor 6 is installed on one side of the support frame 5. The output end of the drive motor 6 is connected to a transmission shaft 21. One end of the transmission shaft 21 is rotatably inserted through the support frame 5. A conveying wheel 4 is installed on one end of the transmission shaft 21. Electric telescopic rods 10 are symmetrically installed on both sides of the protective cover 8. The telescopic end of one side of the electric telescopic rod 10 is slidably connected to the inside of the protective cover 8. A clamping frame 20 is provided at the end of the electric telescopic rod 10. A punching assembly for punching is provided on one side of the protective cover 8. A buffer assembly for protecting the plate is provided on one side of the clamping frame 20.

[0026] In use, the sheet metal can be conveyed to the conveyor wheel 4 via a conveyor belt. The drive motor 6 controls the rotation of the drive shaft 21 and the conveyor wheel 4. The conveyor wheel 4 rotates to convey the sheet metal, which is then punched during the conveying process. After punching, the sheet metal is discharged and collected via the conveyor belt. During punching, the clamping frame 20 can be moved by the electric telescopic rod 10. By moving the two sets of clamping frames 20 closer to each other, the sheet metal can be clamped and fixed. After fixing, the sheet metal is punched, which can prevent the sheet metal from moving during punching and causing defects in the punching. Through the combination of conveying and fixing, the automatic loading and unloading of the sheet metal can be completed to punch the sheet metal. There is no need for the traditional manual loading and unloading method. When there are a large number of sheet metals, there will be no human fatigue, which will avoid affecting the efficiency of punching. At the same time, avoiding the manual loading and unloading method can reduce safety hazards and prevent injuries.

[0027] The punching assembly includes a hydraulic telescopic rod 9, which is installed on one side of the protective cover 8. The telescopic end of the hydraulic telescopic rod 9 is slidably connected to the inside of the protective cover 8. A connecting block 12 is installed at the end of the hydraulic telescopic rod 9, and a hydraulic lifting rod 11 is installed at the bottom of the connecting block 12. A punching mold 13 is detachably installed at the bottom of the hydraulic lifting rod 11.

[0028] In use, after the conveyed plate is fixed by the clamping frame 20, the position of the punching die 13 can be adjusted by the hydraulic telescopic rod 9. After being adjusted to a suitable position, the punching die 13 is lowered by the hydraulic lifting rod 11 to contact the plate and punch holes. The punching die 13 continues to fall to complete the punching of the plate. The position of the punching die 13 can be adjusted again by the hydraulic telescopic rod 9 after it is raised to punch other parts of the plate. The punching of the plate can be completed conveniently when processing powder metallurgy machine parts molds.

[0029] The buffer assembly includes a spring 23, and several sets of springs 23 are respectively installed on one side of the clamping frame 20. A pressure plate 7 is installed at the end of the spring 23. The clamping frame 20 has two sets of guide holes, through which a guide rod 22 is slidably installed. One end of the guide rod 22 is fixed to the pressure plate 7.

[0030] When the clamping frame 20 moves to clamp and fix the plate, the pressure plate 7 first contacts the plate. When in contact, the deformation of the spring 23 can play a buffering role, avoiding the plate from deforming due to excessive contact pressure during clamping. This can effectively protect the plate. The guide rod 22 slides in the guide hole to prevent the pressure plate 7 from shifting when moving.

[0031] To assist in the transport of the boards, such as Figure 2 , 3As shown in Figure 4, an electric lifting rod 14 is installed on the inner wall of the top of the protective cover 8. An installation base 15 is installed at the bottom of the electric lifting rod 14. A rotary motor 16 is installed on one side of the installation base 15. A rotary shaft 19 is connected to the output end of one side of the rotary motor 16. One end of the rotary shaft 19 can rotatably pass through the installation base 15. A rotating roller 18 is installed on one end of the rotary shaft 19.

[0032] When conveying the plate, the electric lifting rod 14 can control the roller 18 to fall. After the roller 18 falls, it can contact the plate and apply a certain pressure to it, thereby preventing slippage during conveying. The rotating motor 16 can control the rotating shaft 19 and the roller 18 to rotate. The roller 18 can assist in conveying the plate by rotating in contact with the plate.

[0033] To maintain stability, such as Figure 1 As shown, the base 1 has several sets of support legs 2 installed at its bottom, and foot pads 3 are installed at the bottom of the support legs 2.

[0034] When in use, the foot pad 3 is made of rubber. The support leg 2 and the foot pad 3 work together to support the device and maintain its stability. The rubber foot pad 3 can increase the anti-slip properties and prevent the device from sliding or shifting unnecessarily.

[0035] To remove impurities, such as Figure 2 As shown, a fixed bracket is provided on one side of the mounting base 15, and a scraper 17 is installed through the fixed bracket;

[0036] When in use, as the roller 18 falls and contacts the plate, the scraper 17 simultaneously contacts the plate. During the plate conveying process, the scraper 17, which is in contact with the plate, can clean its surface, thereby effectively removing attached impurities and stains and preventing impurities and stains from remaining and affecting subsequent processing.

[0037] Example 2

[0038] To prevent the guide rod 22 from dislodging, refer to... Figure 3 , 4 A punching device for processing molds for powder metallurgy machine parts. Compared with embodiment 1, this embodiment makes the following improvements: the guide rod 22 is provided with a limit block at its tail end, and the diameter of the limit block is larger than the diameter of the guide hole.

[0039] During use, the limiting block at the end of the guide rod 22 can limit the guide rod 22 when it slides in the guide hole, thus preventing the guide rod 22 from coming out of the guide hole.
