Description

Technical Field

[0001] This utility model relates to the field of forging forming technology, and in particular to a forging die with a dustproof groove for shaping the inner diameter of a forging. Background Technology

[0002] In modern industrial manufacturing, forging, as an important metal forming process, is widely used in industries such as automobiles, machinery manufacturing, and aerospace. It plays a crucial role, especially in the production of precision forgings with dustproof grooves, such as bearing rings and seals. In traditional forging manufacturing processes, for forgings with dustproof grooves on the inner diameter of the outer ring, the basic shape is usually forged as a whole, and then the dustproof groove is formed by subsequent machining methods such as turning and milling. This process relies on molds to form the main body of the forging. Although the subsequent machining can meet the precision requirements, the process is cumbersome and time-consuming.

[0003] However, the aforementioned traditional process has significant drawbacks. On the one hand, a large amount of metal material is removed during subsequent turning operations, resulting in low material utilization and a significant increase in production costs. On the other hand, multiple machining operations cause severe tool wear, which not only shortens tool life but also reduces production efficiency due to frequent tool replacements. Utility Model Content

[0004] In view of the problems of low material utilization, high production cost, severe tool wear and low production efficiency in the existing traditional forging process for forgings with dustproof grooves, which adopts the method of integral forging followed by machining to form the dustproof groove, this utility model is proposed.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a forging die for a forging inner diameter with a dustproof groove, comprising a base, a vertical plate on one side of the top of the base, a mandrel rotatably mounted on one side of the vertical plate, a protrusion I on one side of the outer wall of the mandrel, and protrusion II symmetrically located on both sides of the outer wall of the mandrel and the protrusion I, auxiliary positioning components symmetrically arranged on the outer circumference of the mandrel, a forging wheel on one side of the vertical plate above the mandrel, a drive motor for driving the forging wheel to rotate on the side of the vertical plate away from the forging wheel, the drive motor being connected to the vertical plate through a lifting component, and a support component for supporting the mandrel on one side of the top of the base.

[0006] As a preferred embodiment, the lifting assembly includes a slider, a groove is provided on one side of the upper part of the vertical plate, the slider is slidably installed in the groove, and the slider is rotatably sleeved on the outside of the output end of the drive motor. The side of the vertical plate away from the forging wheel is provided with a mounting seat connected to the slider, the drive motor is detachably installed on the side of the mounting seat away from the vertical plate, and a hydraulic cylinder is provided at the top of the vertical plate, and the telescopic end of the hydraulic cylinder is fixedly connected to the slider.

[0007] As a preferred embodiment, the mounting base is symmetrically provided with guide blocks on the side near the vertical plate, and the side wall of the vertical plate is symmetrically provided with guide grooves that are adapted to the guide blocks.

[0008] As a preferred embodiment, the outer wall of the slider is symmetrically provided with limiting blocks, and the inner wall of the slide groove is symmetrically provided with limiting grooves that are adapted to the limiting blocks.

[0009] As a preferred embodiment, the auxiliary positioning component includes a bracket, which is arc-shaped. One end of the bracket is rotatably connected to a vertical plate, and a rotating wheel is rotatably mounted on the other end of the bracket. A second hydraulic cylinder is hinged to the side of the bracket away from the spindle, and an installation component is rotatably connected to the side of the second hydraulic cylinder away from the bracket. One end of the installation component is fixedly connected to the vertical plate.

[0010] As a preferred embodiment, the support assembly includes a connecting seat, which is fixedly installed on the top of the base. A support rod is rotatably connected to the inner side of the connecting seat. A through groove adapted to the mandrel is opened on one side of the upper end of the support rod. The side of the support rod away from the vertical plate is hinged to the base through a telescopic rod.

[0011] Compared with the prior art, the present invention has at least the following beneficial effects:

[0012] 1. This utility model forges the forging workpiece by placing it on a mandrel and using a drive motor to press down and rotate it. The forging process directly forms the inner diameter dustproof groove. The device adapts the mandrel to the dustproof groove on the outer ring of the bearing, allowing the dustproof groove to be integrated into the forging process. This reduces machining allowance, lowers costs, and breaks through the limitations of the traditional process of forging before machining. It also solves the problem of severe tool wear caused by multiple machining operations, which not only shortens the tool life but also reduces production efficiency due to frequent tool replacements.

[0013] 2. This utility model uses an auxiliary positioning component to adjust the position of the rotating wheel according to the size of the forging to be processed, so as to limit and guide the forging.

[0014] 3. This utility model can support the mandrel through the support component, thereby improving its stability. Attached Figure Description

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Reference Figures 1-5 As shown, a forging die for a forging with a dustproof groove is provided, comprising a base 1, a vertical plate 2 on one side of the top of the base 1, a mandrel 3 rotatably mounted on one side of the vertical plate 2, a protrusion 4 on one side of the outer wall of the mandrel 3, and protrusions 5 symmetrically positioned on both sides of the outer wall of the mandrel 3 and the protrusion 4, and auxiliary positioning components symmetrically arranged on the outer circumference of the mandrel 3, a forging wheel 6 above the mandrel 3 on one side of the vertical plate 2, and a drive motor 7 for driving the forging wheel 6 to rotate on the side of the vertical plate 2 away from the forging wheel 6, the drive motor 7 being connected to the vertical plate 2 via a lifting component, and a support component for supporting the mandrel 3 on one side of the top of the base 1; by means of the protrusion 4 on the mandrel 3 that is adapted to the dustproof groove, the dustproof groove can be directly formed during forging, reducing subsequent turning processes, significantly reducing production costs and improving production efficiency.

[0024] In this example, the lifting assembly includes a slider 8. A groove 11 is provided on one side of the upper part of the vertical plate 2. The slider 8 is slidably installed in the groove 11 and is rotatably sleeved on the outside of the output end of the drive motor 7. A mounting seat 9 connected to the slider 8 is provided on the side of the vertical plate 2 away from the forging wheel 6. The drive motor 7 is detachably installed on the side of the mounting seat 9 away from the vertical plate 2. A hydraulic cylinder 15 is provided at the top of the vertical plate 2, and the telescopic end of the hydraulic cylinder 15 is fixedly connected to the slider 8. This lifting assembly can flexibly adjust the height of the drive motor 7, thereby controlling the distance between the forging wheel 6 and the mandrel 3, meeting the forging requirements of forgings of different specifications, and improving the versatility of the device.

[0025] In this example, the mounting base 9 is symmetrically provided with guide blocks 10 on the side near the vertical plate 2, and the side wall of the vertical plate 2 is symmetrically provided with guide grooves 12 that are adapted to the guide blocks 10; the cooperation between the guide blocks 10 and the guide grooves 12 provides precise guidance for the movement of the mounting base 9, ensuring the stability of the lifting process of the drive motor 7 and improving the forging accuracy.

[0026] In this example, the outer wall of the slider 8 is symmetrically provided with limiting blocks 13, and the inner wall of the slide groove 11 is symmetrically provided with limiting grooves 14 that are adapted to the limiting blocks 13. The setting of the limiting blocks 13 and the limiting grooves 14 effectively prevents the slider 8 from shifting or disengaging in the slide groove 11, thereby enhancing the reliability and safety of the lifting assembly operation.

[0027] In this example, the auxiliary positioning component includes a bracket 16, which is arc-shaped. One end of the bracket 16 is rotatably connected to the vertical plate 2, and the other end of the bracket 16 is rotatably mounted with a rotating wheel 17. A hydraulic cylinder 18 is hinged to the side of the bracket 16 away from the mandrel 3. A mounting part 19 is rotatably connected to the end of the hydraulic cylinder 18 away from the bracket 16, and one end of the mounting part 19 is fixedly connected to the vertical plate 2. This auxiliary positioning component can flexibly adjust the position of the rotating wheel 17 according to the size of the forging through the hydraulic cylinder 18, so as to achieve precise positioning and guidance of forgings of different specifications, and ensure the stability and efficiency of the forging process.

[0028] In this example, the support assembly includes a connecting seat 22, which is fixedly installed on the top of the base 1. A support rod 20 is rotatably connected to the inner side of the connecting seat 22. A through groove adapted to the mandrel 3 is opened on one side of the upper end of the support rod 20. The side of the support rod 20 away from the vertical plate 2 is hinged to the base 1 through a telescopic rod 21. The support assembly can provide stable support for the mandrel 3, effectively reduce the shaking of the mandrel 3 during the forging process, improve the stability and forging accuracy of the mandrel 3, and extend the service life of the equipment.

[0029] During use, in the preparation stage: the forging to be forged is placed on the mandrel 3. The forging is initially positioned using the protrusion 4 on the mandrel 3 that matches the dustproof groove and the protrusions 5 on both sides. At the same time, according to the size of the forging, the bracket 16 of the auxiliary positioning component is rotated by starting the hydraulic cylinder 18 on one side, and the position of the rotating wheel 17 is adjusted so that it fits against the outer wall of the forging, thus completing the precise positioning and guidance of the forging. The angle of the support rod 20 of the support component is adjusted by the telescopic rod 21 so that the through groove at the upper end of the support rod 20 fits tightly with the mandrel 3, providing stable support for the mandrel 3.

[0030] Forging stage: Start hydraulic cylinder 15, its telescopic end drives the slider 8 to slide down in the groove 11. The slider 8 causes the drive motor 7 and the forging wheel 6 to descend synchronously through the mounting seat 9 until the forging wheel 6 contacts the forging. Then the drive motor 7 starts, driving the forging wheel 6 to rotate, applying pressure and rotational force to the forging, causing the forging to undergo plastic deformation between the forging wheel 6 and the mandrel 3. During this process, the forging material fills the area corresponding to the protrusion 4 on the mandrel 3 under pressure, directly forming the dustproof groove structure. At the same time, with the assistance of structures such as the second protrusion 5, the forging of other parts of the forging is completed.

[0031] Height adjustment and processing adaptability: If forgings of different specifications are required, the height of the drive motor 7 and the forging wheel 6 can be adjusted by hydraulic cylinder 15. By utilizing the cooperation between the guide block 10 on the mounting base 9 and the guide groove 12 of the vertical plate 2, as well as the cooperation between the limit block 13 of the slider 8 and the limit groove 14 of the slide 11, the lifting process of the forging wheel 6 is ensured to be smooth and the positioning is accurate, thereby adapting to the forging requirements of forgings of different sizes.

[0032] Forging complete: Once the forging reaches the required shape and size, the drive motor 7 stops rotating, the hydraulic cylinder 15 drives the forging wheel 6 to rise and reset, and then the forged forging is removed, completing one forging cycle.

[0033] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
