[0024] An embodiment of the present utility model discloses an annealing furnace for the production of high-efficiency bearing steel pipes.

[0025] Referring to Figures 1-4 , an annealing furnace for the production of high-efficiency bearing steel pipes includes an annealing furnace 1 main body and a material storage shell 2. An upper side of one end of the annealing furnace 1 main body is provided with a feeding port. The material storage shell 2 is arranged above the feeding port. The top of the material storage shell 2 is open, which is convenient for replenishing materials into the material storage shell 2. A circular groove is opened at the lower end inside the material storage shell 2. A rotating rod 8 is rotatably arranged inside the circular groove. A turntable 9 is fixedly sleeved on the rod wall of the rotating rod 8. A plurality of material receiving grooves are arranged on the side wall of the turntable 9 in an annular array. Fixed shells 3 are fixedly arranged on the upper surface of the annealing furnace 1 main body and on both sides of the feeding port. A slide block 4 is slidably arranged inside the fixed shell 3. A spring 7 is fixedly arranged on the lower side of the slide block 4. The other end of the spring 7 is fixedly connected to the inner wall of the fixed shell 3, which is convenient for the slide block 4 to reset. A connecting rod 5 is fixedly arranged on the upper side of the slide block 4. The upper end of the connecting rod 5 extends to the outside of the fixed shell 3 and is fixedly connected to a connecting block 6. One side of the connecting block 6 is fixedly connected to the material storage shell 2. A motor 14 is fixedly arranged at the rear of the material storage shell 2. The output end of the motor 14 is fixedly connected to one end of the rotating rod 8. The motor 14 is fixedly connected to the material storage shell 2 through a support frame, making the connection between the motor 14 and the material storage shell 2 more stable.

[0026] Referring to Figures 1-4 , a transmission mechanism for driving the material storage shell 2 to vibrate is arranged at the front end of the rotating rod 8. The transmission mechanism includes a transmission rod 12 and a cam 10. The transmission rod 12 is arranged at the front side of the material storage shell 2 and below the rotating rod 8.

A first gear 11 is fixedly sleeved on the front end of the rotating rod 8. A second gear 13 is fixedly sleeved on the middle end of the transmission rod 12. The first gear 11 is meshed with the second gear 13.

[0027] Referring to Figures 1-4, the tooth number ratio of the first gear 11 to the second gear 13 is 30:1, so that the first gear 11 can drive the second gear 13 to rotate rapidly, and further enable the transmission rod 12 to drive the cam 10 to rotate rapidly.

[0028] In the present utility model, during use, the motor 14 drives the rotating rod 8 to rotate, which causes the turntable 9 to rotate, that is, it can successively rotate the steel pipes in multiple material receiving grooves downward, so that the steel pipes enter the interior of the annealing furnace main body 1 from the feeding port, that is, automatic feeding can be carried out. During the rotation of the rotating rod 8, it will drive the first gear 11 to rotate, and the first gear 11 drives the second gear 13 to rotate, that is, it enables the transmission rod 12 to drive the cam 10 to rotate, and further can drive the storage shell 2 to vibrate up and down, which can effectively prevent the setting caused by the accumulation of more steel pipes.
