[0016] like Figure 1 As shown, this specific embodiment adopts the following technical solution: a gear rolling forming device, including a base 1, a movable seat 2, a guide groove 3, a screw 4, a first motor 5, a second motor 6, a driven gear 7, a driving gear 8, a double rolling mechanism 9, a rotating seat 10, a gear blank 11, a chuck 12, and a fixed seat 13; the upper side of the base 1 is provided with a transverse guide groove 3, and the first motor 5 is fixedly connected to the outer left side of the base 1; the screw 4 is movably connected to the center of the guide groove 3, and the center of the left side of the screw 4 is fixedly connected to the right output shaft of the first motor 5; the lower side of the movable seat 2 is transversely movably connected to the inside of the guide groove 3, and the movable seat... The threaded hole on the lower side of the movable seat 2 is connected to the screw 4. The upper left side of the movable seat 2 is fixedly connected to the motor 6. The output shaft on the right side of the motor 6 is fixedly connected to the drive gear 8. The left side of the rotating seat 10 is movably connected to the upper interior of the movable seat 2. The left side of the rotating seat 10 is fixedly connected to the driven gear 7, and the upper teeth of the driven gear 7 are connected to the drive gear 8. The right side of the rotating seat 10 is provided with a double rolling mechanism 9. The lower left side of the fixed seat 13 is fixedly connected to the right exterior of the base 1. The upper left side of the fixed seat 13 is fixedly connected to the chuck 12, and the left side of the chuck 12 is fixedly connected to the gear blank 11.

[0017] like Figure 2As shown, the specific structure of the double rolling mechanism 9 includes mounting grooves 91, rolling cutter wheels 92, splined shafts 93, fixed covers 94, transmission shafts 95, bevel gear one 96, connecting shafts 97 and bevel gear two 98; there are two mounting grooves 91, which are respectively located inside the right side of the rotating base 10; the bevel gear two 98 is movably connected to the center of the right side of the rotating base 10; there are two transmission shafts 95, which are respectively movably connected to the center of the right side of the rotating base 10. Each drive shaft 95 is externally fixedly connected to a bevel gear 96, and each bevel gear 96 is connected to a bevel gear 98. A connecting shaft 97 is movably connected between the inner surfaces of the two drive shafts 95. There are two spline shafts 93, and each spline shaft 93 is movably connected to the corresponding mounting groove 91 through a fixed cover 94. Each spline shaft 93 is externally fixedly connected to a rolling cutter wheel 92, and the inner and outer sides of the two spline shafts 93 are respectively connected to the spline holes provided in the center of the outer side of the corresponding drive shaft 95.

[0018] The roller 92 has adjusting shims between its two sides and the inner wall of the mounting groove 91; the motor 6 is a geared motor; and the guide groove 3 is a T-shaped guide groove.

[0019] The utility model is used as follows: It has a reasonable and simple structure, low production cost, convenient installation, and complete functions. When the gear rolling forming device is running, the motor 6 (reduction motor) on the movable seat 2 is first started. Its right output shaft drives the driving gear 8 to rotate. The driving gear 8 meshes with the driven gear 7, thereby driving the rotating seat 10 to rotate inside the upper side of the movable seat 2. The double rolling mechanism 9 inside the right side of the rotating seat 10 also starts working. Then, the motor 5 is started, and its right output shaft drives the screw 4 to rotate in the center of the guide groove 3. Since the guide groove 3 is a T-shaped guide groove, it can effectively restrict the movement direction of the movable seat 2, so that the movable seat 2 can only move laterally along the guide groove 3. Furthermore, because the threaded hole on the lower side of the movable seat 2 is connected to the screw 4, the rotation of the screw 4 drives the movable seat 2 to move laterally to the right within the guide groove 3. In addition, the fixed seat 13 is fixed to the outside right side of the base 1, and the chuck 12 on its upper left side firmly fixes the gear blank 11. As the double rolling mechanism 9 rotates... The two rollers 92 can simultaneously roll the gear blank 11, ensuring uniform force during the rolling process. The bevel gear 98 ensures that the two transmission shafts 95 rotate in opposite directions when meshing with the bevel gear 96 on the two transmission shafts 95. The spline shaft 93 is installed in the mounting groove 91 through the fixing cover 94. The outer side of the spline shaft 93 is connected to the spline hole in the center of the outer side of the transmission shaft 95, ensuring that the two rollers 92 have the same speed but opposite rotation directions. This satisfies the requirement that the two rollers 92 can simultaneously roll the gear blank 11 on both sides. The two transmission shafts 95 are internally connected by a connecting shaft 97, ensuring that the axes of the two transmission shafts 95 are on the same straight line. In addition, the adjusting shims between the two sides of the rollers 92 and the inner wall of the mounting groove 91 can finely adjust the position of the rollers 92 according to the actual processing requirements.
