Abstract
Description
Technical Field
[0001] This utility model relates to the field of powder metallurgy manufacturing technology, and in particular to a hole-forming device for powder metallurgy products that do not enter the intermediate mold. Background Technology
[0002] Powder metallurgy products are parts or materials made from metal or alloy powders through forming and sintering processes. Due to their high precision and minimal or no cutting, they are widely used in machinery, electronics, and other fields. During the production of powder metallurgy products, uneven powder pressing density, mold wear, and blank shrinkage deformation can easily lead to dimensional deviations and irregular shapes in the product's holes, preventing them from smoothly entering the intermediate mold. A hole-forming device for powder metallurgy products that do not enter the intermediate mold can correct the hole positions through mechanical extrusion, calibration, and shaping, ensuring that the dimensional accuracy and shape meet the requirements of the intermediate mold. This guarantees a precise fit between the product and the intermediate mold, reduces scrap rates, improves production efficiency, and simultaneously reduces mold wear and saves production costs.
[0003] A hole-forming device for powder metallurgy jigs that fail to fit into the intermediate mold typically consists of a positioning mechanism, hole-forming execution components, a drive assembly, and a control assembly. The positioning mechanism precisely fixes the jig, ensuring accurate hole positioning. The hole-forming execution components, such as hole-forming pins or forming molds, directly act on the jig's hole positions for calibration and shaping. The drive assembly provides power to the hole-forming execution components, enabling precise movement. The control assembly adjusts the parameters of the drive assembly, monitors the hole-forming process, and ensures hole-forming accuracy and device operational stability. All components work together to solve the problem of jigs failing to fit into the intermediate mold.
[0004] In existing technologies, some powder metallurgy die-forming devices that fail to insert the product into the intermediate mold first guide the product into the intermediate mold before pressing and shaping. Since inserting the product into the intermediate mold requires alignment between the product and the mold before pressing, only about 30-40 pieces can be shaped per minute. If the speed is increased further, mold jamming is highly likely. Therefore, a die-forming device for powder metallurgy die-forming that fails to insert the product into the intermediate mold is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a hole-forming device for powder metallurgy products that do not enter the middle mold, aiming to improve the problem that the existing technology can only form about 30 to 40 per minute, and if it is faster, it is very easy to cause mold jamming.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A device for straightening holes in powder metallurgy products that do not fit into the intermediate mold includes a worktable. A lower pressure block is fixedly connected to the top of the worktable. Two positioning chucks are slidably connected to the top of the worktable. A positioning slider block is fixedly connected to the far side of each of the two positioning chucks. A limit block is fixedly connected to the far side of each of the two positioning slider blocks. A slider spring adjusting seat is fixedly connected to the far side of each of the two limit blocks. A feeding guide rail is fixedly connected to the top of the worktable. A feeding guide baffle is fixedly connected inside the feeding guide rail. A material unloading component for automatic unloading is fixedly connected to the rear side of the worktable.
[0008] As a further description of the above technical solution:
[0009] The material pouring assembly includes a support frame 1. The front side of the support frame 1 is fixedly connected to the rear side of the workbench. A protective shell is fixedly connected to the bottom of the support frame 1. A motor is slidably connected to the bottom of the protective shell. A rotating rod is fixedly connected to the drive end of the motor. A gear is fixedly connected to the outside of the rotating rod. A force-applying inclined plate is fixedly connected to the top of the rotating rod. A rack is fixedly connected to the inner wall of the protective shell. A rotating plate is rotatably connected to the top of the support frame 1.
[0010] As a further description of the above technical solution:
[0011] A vibratory feeder is fixedly connected to the right side of the feed guide rail, and a support frame is fixedly connected to the right side of the worktable.
[0012] As a further description of the above technical solution:
[0013] A flat feeder is fixedly connected to the top of the second support frame, a connecting plate is fixedly connected to the top of the flat feeder, and the top of the connecting plate is fixedly connected to the bottom of the feed guide rail.
[0014] As a further description of the above technical solution:
[0015] The top of the workbench is fixedly connected to two telescopic columns, the top of the two telescopic columns is fixedly connected to a lifting component, and the bottom of the lifting component is fixedly connected to an upper punch.
[0016] As a further description of the above technical solution:
[0017] The rack is meshed with the gear, and the rotating rod is rotatably connected to the inner wall of the protective shell.
[0018] As a further description of the above technical solution:
[0019] The top of the rotating plate is fixedly connected to a placement box, and the bottom of the force-applying inclined plate is slidably connected to the bottom of the placement box.
[0020] As a further description of the above technical solution:
[0021] The rotating rod is externally slidably connected to the bottom of the support frame, the rear side of the workbench is fixedly connected to the inclined plate, and the top of the workbench is fixedly connected to the discharge channel.
[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, the material enters the working area under the action of the feeding guide rail and is fixed under the action of the positioning chuck. At this time, the upper punch drills the hole in the product and separates the mold from the product, allowing the material to enter the next part. This achieves a doubling of the hole drilling speed and prevents the equipment from jamming. In addition, doubling the hole drilling speed can significantly improve the production efficiency of powder metallurgy products, thereby shortening the single batch processing cycle to meet the needs of large-scale production.
[0024] 2. In this utility model, the motor runs, causing the rotating rod to rotate. Under the action of the gear and rack, the rotating rod drives the force-applying inclined plate to move, causing the force-applying inclined plate to apply force to the placement box, causing the placement box to tilt, thereby realizing automatic unloading of products. In addition, it can greatly improve the automation level of the hole-forming operation of powder metallurgy products, thereby reducing the tedious operation and manpower input of manual unloading.

[0031] 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.
[0032] Reference Figure 2 and Figure 3 This utility model provides an embodiment of a hole-forming device for powder metallurgy products that do not fit into the intermediate mold. The device includes a worktable 1, which is the foundation of the entire equipment and the place where holes are drilled, ensuring stability. A lower pressure block 2 is fixedly connected to the top of the worktable 1, pressing and fixing the product to ensure stability. Two positioning clamps 3 are slidably connected to the top of the worktable 1, fixing the sides of the product to ensure stability. Positioning slider blocks 6 are fixedly connected to the opposite sides of the two positioning clamps 3. Limit blocks 4 are fixedly connected to the opposite sides of the two positioning slider blocks 6. Slider spring adjustment seats 5 are fixedly connected to the opposite sides of the two limit blocks 4. The slider spring adjustment seats 5 receive the pushing force from the operator, thereby adjusting the limit blocks 4 to allow the positioning slider blocks 6 to move.
[0033] The top of the workbench 1 is fixedly connected to a feeding guide rail 8, which stably transports the product to the working area for straightening. Inside the feeding guide rail 8, a feeding guide baffle 7 is fixedly connected to block the product and ensure that the product enters the working area stably. The rear side of the workbench 1 is fixedly connected to a discharging component for automatic unloading.
[0034] Reference Figure 2 and Figure 4The material pouring assembly includes a support frame 12, the front of which is fixedly connected to the rear of the workbench 1. The support frame 12 supports the place where the product is placed on top, making it stable. A protective shell 13 is fixedly connected to the bottom of the support frame 12, which protects the internal material pouring assembly and makes it stable. A motor 14 is slidably connected to the bottom of the protective shell 13. A rotating rod 15 is fixedly connected to the drive end of the motor 14. A gear 16 is fixedly connected to the outside of the rotating rod 15. A force-applying inclined plate 18 is fixedly connected to the top of the rotating rod 15. A rack 17 is fixedly connected to the inner wall of the protective shell 13. A rotating plate 19 is rotatably connected to the top of the support frame 12. The motor 14 is the driving source of the material pouring assembly, thereby driving the rotating rod 15 to rotate. The gear 16 rotates when the rotating rod 15 rotates. The rack 17 is fixed inside the protective shell 13, so that the gear 16 moves, thereby indirectly driving the rotating rod 15 to move. The rotating plate 19 receives external force and thus rotates.
[0035] Reference Figures 1 to 3 A vibrating plate 23 is fixedly connected to the right side of the feeding guide rail 8. The vibrating plate 23 vibrates and transports the internal products. A support frame 25 is fixedly connected to the right side of the worktable 1. A flat conveyor 26 is fixedly connected to the top of the support frame 25. A connecting plate 24 is fixedly connected to the top of the flat conveyor 26. The top of the connecting plate 24 is fixedly connected to the bottom of the feeding guide rail 8. The support frame 25 supports the top flat conveyor 26. The flat conveyor 26 stabilizes the feeding guide rail during vibration. The connecting plate 24 connects the flat conveyor 26 and the feeding guide rail 8. Two telescopic columns 21 are fixedly connected to the top of the worktable 1. A lifting component 22 is fixedly connected to the top of the two telescopic columns 21. An upper punch 10 is fixedly connected to the bottom of the lifting component 22. The telescopic columns 21 drive the lifting component 22 to move up and down to stabilize it. The upper punch 10 punches the product and makes the product leave the mold.
[0036] The rack 17 is externally meshed with the gear 16. The gear 16 receives the rotational force from the rotating rod 15 and moves under the action of the rack 17. The rotating rod 15 is externally rotatably connected to the inner wall of the protective shell 13. The rotating rod 15 receives the rotational force from the motor 14 and moves accordingly. A placement box 20 is fixedly connected to the top of the rotating plate 19. The placement box 20 is used to place the prepared products. The bottom of the force-applying inclined plate 18 is slidably connected to the bottom of the placement box 20. The force-applying inclined plate 18 is located on the rotating rod. Under the action of 15, force is applied to the placement box 20, causing it to tilt. The outside of the rotating rod 15 is slidably connected to the bottom of the support frame 12. The rotating rod 15 moves under the meshing action of the gear 16 and the rack 17. The rear side of the worktable 1 is fixedly connected to the inclined plate 11. The inclined plate 11 is used to put the prepared product into the placement box 20. The top of the worktable 1 is fixedly connected to the discharge channel 9, which allows the product to be transported stably.
[0037] Working principle: The product enters the feeding guide rail 8 under the action of the vibrating plate 23, and moves slowly under the vibration of the flat conveyor 26. Under the action of the feeding guide baffle 7, the product enters the working area stably. After the product enters, the positioning clamps 3 on both sides position and clamp the product to fix it. At this time, the equipment moves the top lifting part 22, which moves the bottom upper punch 10, which applies force to the product to form a hole. After completion, the upper punch 10 separates the mold and the product, allowing the product to enter the placement box 20. This doubles the hole forming speed and prevents the equipment from jamming. In addition, doubling the hole forming speed can significantly improve the production efficiency of powder metallurgy products, thereby shortening the single batch processing cycle to meet the needs of large-scale production.
[0038] When there are too many placement boxes 20, the operator starts the motor 14. The motor 14 drives the rotating rod 15 to rotate, which in turn rotates the gear 16, causing the gear 16 to contact the rack 17. This causes the rotating rod 15 to move, which in turn moves the top force-applying inclined plate 18. The force-applying inclined plate 18 applies force to the placement box 20, causing the placement inclined plate to rotate and thus conveying the products inside the placement inclined plate. This achieves automatic unloading of products and can significantly improve the automation level of powder metallurgy die forming operations, thereby reducing the tedious operation and manpower input of manual unloading.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
