Detailed Implementation

[0019] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present application belongs.

[0020] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0021] like Figures 2-5 As shown, a gear disc forging processing and shifting mechanism includes a hot forging press A 100. The worktable of the hot forging press A 100 is arranged from left to right as follows: an upsetting station, a pre-forging station, a final forging station, and a punching station. A shifting robot A200, capable of lifting, moving forward and backward, and moving left and right, is located behind the worktable of the hot forging press. This utility model of a gear disc forging processing and shifting mechanism enables the completion of multiple processes—upsetting, pre-forging, final forging, and punching—of a gear disc forging on a single hot forging press. The shifting robot facilitates the transfer of the gear disc forging between different stations, reducing the transfer distance, making it convenient, practical, and efficient, while minimizing manual intervention and improving production safety.

[0022] In this embodiment, the displacement manipulator A 200 includes a base plate A 210. A pair of gripping arms A 230 with their gripping ends facing forward are provided at the front end of the base plate. A drive cylinder A 220 is provided on the base plate to drive the opening and closing of the two gripping arms. The rear parts of the gripping arms are hinged to the base plate, and the hinged parts of the gripping arms are provided with extension handles A 231. Connecting rods A 240 are respectively connected between the telescopic rod of the drive cylinder and the extension handles of the two gripping arms. The drive cylinder A 220 can be a pneumatic cylinder or a hydraulic cylinder. The extension handles A 231 of the two gripping arms are bent outward to form a V-shape. When the telescopic rod of the drive cylinder A 220 extends, it pushes the gripping ends of the two gripping arms to clamp through the connecting rod. When the telescopic rod of the drive cylinder A 220 retracts, it pulls the gripping ends of the two gripping arms to release through the connecting rod, thus realizing the opening and closing of the two gripping arms.

[0023] In this embodiment, in order to achieve precise positioning, a V-shaped positioning block A232 is provided on the opposite side of the clamping ends of the two clamping arms.

[0024] In this embodiment, a longitudinal linear slide A 250 is provided below the displacement robot, and the displacement robot is mounted on the slide base of the longitudinal linear slide. A transverse linear slide A 260 is provided below the longitudinal linear slide, and the longitudinal linear slide is mounted on the slide base of the transverse linear slide. A lifting frame driven by a lifting cylinder (not shown in the figure) is provided below the transverse linear slide. The lifting cylinder can be a hydraulic cylinder and is located below the lifting frame. The transverse linear slide is mounted on the lifting frame A 270.

[0025] The working process of the transfer robot: When picking up the material, the longitudinal linear slide controls the transfer robot to extend forward, so that the two gripping arms of the transfer robot are located on both sides of the gear disk forging. Then, the drive cylinder drives the two gripping arms to clamp the gear disk forging. Next, the lifting frame controls the transfer robot to rise, and the transverse linear slide controls the robot to move to the right above the next station. Then, the transfer robot descends, the two gripping arms release the material, and the transfer robot moves backward to exit.

[0026] In this embodiment, the hot forging press has a lower upsetting die A 110 on the upsetting station on the worktable, and an upper upsetting die A 120 that works in conjunction with the lower upsetting die on the lower side of the slide of the hot forging press.

[0027] In this embodiment, the hot forging press has a lower forming die A 130 on the worktable at the pre-forging station and the final forging station, and an upper forming die A 140 on the lower side of the slide of the hot forging press that works in conjunction with the lower forming die. A forming cavity is formed between the upper forming die and the lower forming die.

[0028] In this embodiment, a lower punching die A 150 is provided on the worktable of the hot forging press at the punching station, and an upper punching die A 160 is provided on the lower side of the slide of the hot forging press to cooperate with the lower punching die.

[0029] The upper punching die A160 includes an upper die base A161 and an upper template A162 located above the upper die base A161. A spring A164 is provided between the upper die base A161 and the upper template A162. A cavity adapted to the gear disc forging is formed between the upper die base A161 and the lower punching die A150. A seat hole is opened in the middle of the upper die base A161, and a punching die A163 whose upper end is fixedly connected to the upper template A162 is provided in the seat hole. A blanking hole adapted to the punching die A163 is opened in the middle of the lower punching die A150.

Those skilled in the art should understand that a preferred numerical range is merely a numerical range that provides a more significant or representative technical effect among a wide range of practicable values. Due to the large number of numerical values, it is impossible to enumerate them exhaustively. Therefore, only some numerical values ​​are disclosed in the present invention to illustrate the technical solution of the present invention. Furthermore, the numerical values ​​listed above should not be construed as limiting the scope of protection of the present invention.

[0031] If the present invention discloses or involves components or structural parts that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by integral molding using a casting process) (except where it is obviously not possible to use an integrated molding process).
