A servo motor is fixedly installed on the right side wall of the base. The drive shaft of the servo motor is fixedly connected to the end of the bidirectional lead screw located outside the cavity. Two movable seats are threadedly sleeved at the end of the bidirectional lead screw located inside the cavity. The upper end of the cavity has two rectangular openings. The upper ends of the two movable seats vertically penetrate the two rectangular openings and are fixed to the lower ends of the two forming seats respectively.

[0007] Preferably, a coupling is fixedly connected to the drive shaft of the servo motor, and the end of the bidirectional lead screw located outside the cavity is fixedly connected to the coupling.

[0008] Preferably, the bottom of the cavity is provided with two limiting slide grooves, and the two movable seats are respectively inserted into the two limiting slide grooves and slide against each other. The two limiting slide grooves are respectively facing the two rectangular openings and are of equal length.

[0009] Preferably, a rectangular slot is provided at the lower end of the center position of the two molding seats, and a rectangular protrusion is provided on the top surface of the two rectangular slots. A rectangular slot is provided at the upper end of the center position of the two movable seats.

[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 A high-strength heavy-duty automobile half-shaft processing and forming device includes a base 1 and two forming seats 2. The base 1 has a cavity 3. A bidirectional lead screw 4 is horizontally rotatably threaded through the inner walls of the left and right sides of the cavity 3. A servo motor 5 is fixedly installed on the right side wall of the base 1. The drive shaft of the servo motor 5 is fixedly connected to one end of the bidirectional lead screw 4 located outside the cavity 3. A coupling 8 is fixedly connected to the drive shaft of the servo motor 5. The end of the bidirectional lead screw 4 located outside the cavity 3 is fixedly connected to the coupling 8. The servo motor 5, in conjunction with the coupling 8, drives the bidirectional lead screw 4 to rotate. This rotation causes two threaded movable seats 6 to move along a rectangular opening 7 under the limiting action of a limiting groove 9. The two-way lead screw 4, located inside the cavity 3, has two movable seats 6 threaded onto one end. The upper end of the cavity 3 has two rectangular openings 7, and the upper ends of the two movable seats 6 vertically penetrate the two rectangular openings 7. The bottom of the cavity 3 has two limiting grooves 9, and the two movable seats 6 are respectively inserted into the two limiting grooves 9 and slide against each other. The two limiting grooves 9 are respectively opposite the two rectangular openings 7 and are of equal length. The limiting grooves 9, in conjunction with the rectangular openings 7, limit the movable seats 6, preventing the rotation of the two-way lead screw 4 from causing the two movable seats 6 to rotate. This allows the movable seats 6 to move horizontally only with the rotation of the two-way lead screw 4, and limits the horizontal movement range of the movable seats 6.

[0023] The two movable seats 6 are fixed to the lower ends of the two molding seats 2 respectively. A rectangular slot 10 is provided at the lower end of the center of each of the two molding seats 2. A rectangular protrusion 11 is provided on the top surface of each of the two rectangular slots 10. A rectangular groove 12 is provided at the upper end of the center of each of the two movable seats 6. The upper ends of the two movable seats 6 are respectively inserted into the two rectangular slots 10, and the rectangular protrusions 11 are inserted into the rectangular grooves 12. Two bolts 13 are threaded through the inner walls of the front and rear sides of each of the two rectangular slots 10. Several bolts 13 are threaded to the side walls of the movable seats 6. The two molding seats 2 are respectively connected to the two movable seats 6, so that the upper ends of the two movable seats 6 are respectively inserted into the rectangular slots 10 at the lower ends of the two molding seats 2, and the two rectangular protrusions 11 are respectively inserted into the rectangular grooves 12 at the upper ends of the two movable seats 6. Several bolts 13 are threaded through the rectangular slots 10 and then... The movable seat 6 has a threaded connection on its side wall, which effectively fixes the forming seat 2 to the upper end of the movable seat 6. The rectangular protrusion 11 is integrally formed with the movable seat 6. The lower ends of the two forming seats 2 near the four corners are embedded with limiting balls 14. Several limiting balls 14 roll and abut against the upper end of the base 1. The opposite side walls of the two forming seats 2 near the lower end are provided with arc-shaped inset grooves 15 and arc-shaped inserts 16. The arc-shaped inserts 16 are directly opposite the arc-shaped inset grooves 15 and can be seamlessly inserted. When the two forming seats 2 are smoothly connected, the arc-shaped inserts 16 can be seamlessly inserted into the arc-shaped inset grooves 15, so that the two forming seats 2 can be seamlessly connected, which is convenient for the forming process of the automobile half shaft. After the forming is completed, the servo motor 5 is started again to drive the two forming seats 2 to separate, so as to quickly remove the formed automobile half shaft and clean and recycle it in time, avoiding waste of raw materials.

[0024] In use, the two forming seats 2 are respectively connected to the two movable seats 6, so that the upper ends of the two movable seats 6 are respectively inserted into the rectangular slots 10 at the lower ends of the two forming seats 2, and the two rectangular protrusions 11 are respectively inserted into the rectangular slots 12 at the upper ends of the two movable seats 6. Several bolts 13 are threaded through the rectangular slots 10 and connected to the side wall of the movable seats 6, effectively fixing the forming seats 2 to the upper end of the movable seats 6. The servo motor 5 is started and the coupling 8 drives the bidirectional lead screw 4 to rotate. The rotation of the bidirectional lead screw 4 drives the two threaded movable seats 6 to move along the rectangular slots 12 under the limiting action of the limiting groove 9. The two movable seats 6 move horizontally relative to each other, causing the two forming seats 2 to move horizontally along the upper end of the base 1 with the help of several limiting balls 14. The two forming seats 2 can be smoothly connected to prevent the connection from shifting and ensure the forming quality. When the two forming seats 2 are smoothly connected, the arc-shaped insert 16 can be seamlessly embedded in the arc-shaped inner groove 15, so that the two forming seats 2 can be seamlessly connected, which is convenient for the forming process of the automobile half shaft. After the forming is completed, the servo motor 5 is started again to drive the two forming seats 2 to separate, so as to quickly remove the formed automobile half shaft and clean and recycle it in time, avoiding the waste of raw materials.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
