Description

Technical Field

[0001] This utility model relates to the field of gear processing technology, and in particular to a gear blank reaming forging die. Background Technology

[0002] Gear blank reaming and forging is a crucial step in gear manufacturing. This process allows the gear blank to achieve the required dimensions and shape, providing a solid foundation for subsequent gear processing. In this field, the gear blank reaming and forging die is a core component; its design rationality, machining accuracy, and ease of use have a decisive impact on the overall quality and processing efficiency of the gear.

[0003] Especially in the core process of gear blank reaming and forging, existing forging dies have gradually revealed a series of obvious limitations and technical problems when handling gear blanks of different specifications and materials. Specifically, utility model patent CN216027840U discloses a gear blank reaming and forging die, which includes a force-applying plate, an upper extrusion die, a reaming cylinder, a lower extrusion die, and a pushing assembly. By separating the upper and lower extrusion dies, the return force of a return spring is used to push the metal blank at the reaming point inside the reaming cylinder, making it easier for production personnel to collect the metal blank during reaming. Although this design improves production convenience to some extent, the function of existing forging dies remains relatively limited.

[0004] Specifically, existing forging dies can only provide basic support for gear blanks, lacking an effective clamping and stabilizing mechanism for materials of different specifications. This leads to material displacement or wobbling during processing, affecting machining accuracy. Furthermore, removing the processed material is inconvenient, typically requiring manual operation by production personnel, increasing labor intensity and significantly reducing processing efficiency. These problems directly contribute to the complexity and inefficiency of the gear blank reaming and forging process, making it difficult to meet the demands of modern, high-efficiency production. Therefore, to address the numerous shortcomings of existing technologies, we urgently need an innovative gear blank reaming and forging die to solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a gear blank reaming forging die, which solves the problem that the existing forging dies can only provide basic support for gear blank materials and lack an effective clamping and stabilizing mechanism for material plates of different specifications. This leads to the material being prone to displacement or shaking during processing, affecting processing accuracy. At the same time, it is not convenient to remove the processed material, which usually requires manual operation by production personnel, which not only increases labor intensity but also greatly reduces processing efficiency.

[0006] To achieve the above objectives, this utility model provides a gear blank reaming forging die, including a frame.

[0007] It also includes a ring-shaped hydraulic pipe fixedly connected to the bottom inner side of the frame, and a hydraulic cylinder fixedly connected to the top of the frame by bolts;

[0008] The inner side of the annular hydraulic pipe is connected to several piston pipes, and each piston pipe has a piston on its inner side. Each piston has a piston rod fixedly connected to one side. Each piston rod has an arc-shaped clamp fixedly connected to one end. The top of the frame is fixedly connected to a hydraulic pump by bolts, and the outlet of the hydraulic pump is connected to one side of the annular hydraulic pipe. An enlarging head is provided on one side of the inner side of the frame, and the output shaft of the hydraulic cylinder passes through the top of the frame and is fixedly connected to the top of the enlarging head. A bottom groove is opened at the bottom of the frame, and a support plate is provided on the inner side of the bottom groove.

[0009] The bottom of the frame is fixedly connected to a bottom frame, and the bottom plate is fixedly connected to the inner side of the bottom frame. A cylinder is fixedly connected to the bottom of the bottom plate by bolts, and the output shaft of the cylinder passes through the bottom of the bottom plate and is fixedly connected to the bottom of the support plate.

[0010] All the curved clamps have sliders fixedly connected to their bottoms, and all the sliders are slidably connected to the bottom of the frame through grooves.

[0011] The top of the expanding head is fixedly connected to a bearing plate, and the top of the bearing plate is fixedly connected to the output shaft of the hydraulic cylinder. Both sides of the bearing plate are fixedly connected to sliding rods, and one end of each sliding rod is slidably connected to the inner wall of the frame through a vertical groove.

[0012] One side of the annular hydraulic pipe is connected to a connecting pipe, and one end of the connecting pipe is connected to the interface of the hydraulic pump.

[0013] All the arc-shaped clamps are distributed in a ring around the center of the annular hydraulic pipe.

[0014] This utility model discloses a gear blank reaming forging die. Through the cooperation of a hydraulic pump, piston tube, piston, piston rod, and arc-shaped clamping plate, it achieves stable clamping of material plates of different specifications. This design not only improves stability during processing but also ensures processing accuracy, preventing displacement or shaking of the material plate during processing. Simply starting the hydraulic pump and hydraulic cylinder completes the clamping and reaming of the material plate. Simultaneously, the support plate design allows for easy removal of the processed material plate without manual operation or laborious handling, greatly improving work efficiency.

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0023] Please see Figure 1-5 A gear blank reaming forging mold includes a frame 1, an annular hydraulic pipe 4 fixedly connected to the bottom inner side of the frame 1, and a hydraulic cylinder 10 fixedly connected to the top of the frame 1 by bolts; the inner side of the annular hydraulic pipe 4 is connected to several piston pipes 5, and all piston pipes 5 are provided with pistons 20 on their inner sides, and all pistons 20 are fixedly connected with piston rods 6 on one side, wherein an arc-shaped clamping plate 7 is fixedly connected to one end of all piston rods 6; a hydraulic pump 13 is fixedly connected to the top of the frame 1 by bolts, and the outlet of the hydraulic pump 13 is connected to one side of the annular hydraulic pipe 4; a reaming head 8 is provided on one side of the inner side of the frame 1, and the output shaft of the hydraulic cylinder 10 passes through the top of the frame 1 and is fixedly connected to the top of the reaming head 8; a bottom groove 18 is opened at the bottom of the frame 1, and a support plate 19 is provided on the inner side of the bottom groove 18.

[0024] First, the gear blank material plate to be forged and expanded is placed in the annular hydraulic pipe 4 at the bottom inner side of the frame 1. This allows the material plate to be initially positioned, preparing it for subsequent processing. Next, the hydraulic pump 13 is started, pumping hydraulic oil through the annular hydraulic pipe 4 into all the piston pipes 5. Since the annular hydraulic pipe 4 is connected to the inside of the piston pipes 5, the hydraulic oil can flow smoothly into the piston pipes 5. Under the pressure of the hydraulic oil, the piston 20 in the piston pipe 5 begins to move, pushing the arc-shaped clamping plate 7 through the piston rod 6. Under the push of the piston rod 6, the arc-shaped clamping plate 7 gradually approaches and clamps the material plate, achieving a stable gripping of the material plate. This method is suitable not only for material plates of different specifications, but also for materials plates of adjustable clamping force, ensuring stability and accuracy during processing. After the material plate is securely gripped, the hydraulic cylinder 10 is activated. The output shaft of the hydraulic cylinder 10 passes through the top of the frame 1 and is fixedly connected to the top of the expanding head 8. Driven by the hydraulic cylinder 10, the reaming head 8 begins to move downwards, gradually approaching and contacting the material plate. As the reaming head 8 continues to move downwards, it performs extrusion and reaming operations on the material plate. After the material plate is processed, it needs to be removed. At this point, simply move the support plate 19 at the bottom of the frame 1 upwards. The design of the support plate 19 allows it to easily support the processed material plate and move it upwards to a certain height. In this way, production personnel can easily remove the processed material plate without manual operation or laborious handling, greatly improving work efficiency.

[0025] Furthermore, a bottom frame 2 is fixedly connected to the bottom of the frame 1, and a bottom plate 3 is fixedly connected to the inner side of the bottom frame 2. A cylinder 15 is fixedly connected to the bottom of the bottom plate 3 by bolts, and the output shaft of the cylinder 15 passes through the bottom of the bottom plate 3 and is fixedly connected to the bottom of the support plate 19. When the material plate is processed, the cylinder 15 is started, and its output shaft pushes the support plate 19 upward, achieving the effect of automatically lifting the support plate 19. This allows production personnel to easily remove the processed material plate without manual operation or laborious handling, further improving work efficiency.

[0026] Furthermore, all the bottom of the arc-shaped clamping plates 7 are fixedly connected to sliders 16, and all the sliders 16 are slidably connected to the inner bottom of the frame 1 through the slide groove 17. When the hydraulic pump 13 works, the piston rod 6 pushes the arc-shaped clamping plates 7 to move. The arc-shaped clamping plates 7 slide in the slide groove 17 through the sliders 16, realizing the stable clamping of the material plate and achieving the effect of stable and smooth movement of the arc-shaped clamping plates 7. This ensures the stability and accuracy during the clamping process, while reducing friction and wear and extending the service life of the mold.

[0027] Furthermore, a bearing plate 9 is fixedly connected to the top of the reaming head 8, and the top of the bearing plate 9 is fixedly connected to the output shaft of the hydraulic cylinder 10. Slide rods 11 are fixedly connected to both sides of the bearing plate 9, and one end of each slide rod 11 is slidably connected to the inner wall of the frame 1 through the vertical groove 12. When the hydraulic cylinder 10 works, its output shaft pushes the bearing plate 9 downward, and the bearing plate 9 drives the reaming head 8 downward. At the same time, the slide rods 11 slide in the vertical groove 12, which plays a guiding and stabilizing role, achieving the effect of stable downward movement of the reaming head 8, ensuring the accuracy and stability during the reaming process, and improving the processing quality.

[0028] Furthermore, a connecting pipe 14 is connected to one side of the annular hydraulic pipe 4, and one end of the connecting pipe 14 is connected to the interface of the hydraulic pump 13.

[0029] Furthermore, all the arc-shaped clamps 7 are distributed in a ring around the center of the annular hydraulic pipe 4.

[0030] In summary:

[0031] First, the gear blank material plate to be expanded and forged is placed in the annular hydraulic pipe 4 at the bottom inner side of the frame 1, thus initially positioning the material plate and laying a good foundation for subsequent processing. Next, the hydraulic pump 13 is started, pumping hydraulic oil through the connecting pipe 14 into all the piston pipes 5 via the annular hydraulic pipe 4. Since the annular hydraulic pipe 4 is connected to the inside of the piston pipes 5, the hydraulic oil flows smoothly into the piston pipes 5. Under the pressure of the hydraulic oil, the piston 20 inside the piston pipe 5 begins to move, pushing the arc-shaped clamping plate 7 through the piston rod 6. Driven by the piston rod 6, the arc-shaped clamping plate 7 slides within the slide groove 17 via the slider 16 fixedly connected to its bottom, gradually approaching and clamping the material plate, achieving stable clamping of the material plate. This method is suitable not only for material plates of different specifications but also allows for adjustable clamping force, ensuring stability and precision during processing. After the material plate is securely clamped, the hydraulic cylinder 10 is activated. The output shaft of the hydraulic cylinder 10 passes through the top of the frame 1 and is connected to the support plate 9, which is fixedly connected to the top of the reaming head 8. Driven by the hydraulic cylinder 10, the support plate 9 moves the reaming head 8 downward, while the slide rod 11 slides in the vertical groove 12, playing a guiding and stabilizing role. As the reaming head 8 moves downward, it gradually approaches and contacts the material plate, performing extrusion and reaming. After the material plate is processed, it needs to be removed. At this time, the cylinder 15 is activated, and its output shaft pushes the support plate 19 upward. The design of the support plate 19 allows it to easily support the processed material plate and move it to a certain height. In this way, production personnel can easily remove the processed material plate without manual operation or laborious handling. The material plate is stably supported by the coordinated arrangement of the annular hydraulic pipe 4, piston pipe 5, piston 20, piston rod 6, and arc-shaped clamping plate 7. The annular distribution of the arc-shaped clamping plates 7 and the sliding connection between the slider 16 and the slide groove 17 ensure stability and accuracy during clamping, while reducing friction and wear and extending the service life of the mold. The cooperation between the hydraulic cylinder 10, the bearing plate 9, the reaming head 8, the slide rod 11, and the vertical groove 12 enables the reaming head 8 to move stably downwards, ensuring accuracy and stability during the reaming process and improving processing quality. The cooperation between the cylinder 15 and the support plate 19 enables automated lifting of the processed material plate, allowing production personnel to easily remove the processed material plate without manual operation or strenuous handling, further improving work efficiency. The connecting pipe 14 ensures smooth transmission of hydraulic oil from the hydraulic pump 13 to the annular hydraulic pipe 4, providing a strong guarantee for the pushing action of the piston 20 in the piston pipe 5.

Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
