A baffle 6 is rotatably connected to the side of the movable plate 5 away from the push block 4. A gear 7 is fixedly connected to the inside of the baffle 6. A rack 8 is slidably connected to the inside of the movable plate 5. The rack 8 is meshed with the gear 7. A slide groove 9 is provided inside the base 1 and on the corresponding two sides of the rack 8. A slide rod 10 is slidably connected to the inside of the slide groove 9. The slide rod 10 is fixedly connected to the rack 8. The slide groove 9 consists of three parts, a short straight groove close to the push block 4, a long straight groove away from the push block 4, and an inclined groove connecting the short straight groove and the long straight groove. The slide rod 10 can slide in the slide groove 9.

[0025] The corresponding two side edges of the rack 8 are provided with limiting grooves 12, and the limiting grooves 12 are internally slidably connected to limiting blocks 13, and the limiting blocks 13 are fixedly connected to the movable plate 5. The rack 8 is limited by the limiting grooves 12 and the limiting blocks 13 to ensure that the rack 8 can always mesh with the gear 7.

[0026] The top of the base 1 and the corresponding two side edges of the movable plate 5 are fixedly connected with supporting plates 14, which are used to support the steel pipe.

[0027] The corresponding two sides of the base 1 are fixedly connected with a fixing frame 15, and the outer side of the fixing frame 15 away from the base 1 is fixedly connected with an electric push rod 16, the output shaft of the electric push rod 16 vertically penetrates the fixing frame 15 and extends to the other side of the fixing frame 15, the output shaft of the electric push rod 16 is slidably connected to the fixing frame 15, and the output end of the electric push rod 16 is fixedly connected with a mounting frame 17, and the inside of the mounting frame 17 is rotatably connected with a roller 18, and the steel pipe passing through the two rollers 18 is rolled into a required size by the roller 18, or the steel pipe is rolled by the roller 18.

[0028] The use steps of the utility model are as follows: when the stainless steel pipe cold rolling and calendering equipment is in use, the steel pipe is placed on the support plate 14, the motor 3 is started to drive the screw rod 11 to rotate forward, the screw rod 11 drives the push block 4 to push the steel pipe close to the roller 18, so that the steel pipe passes through the roller 18. When the steel pipe just enters the roller 18, the slide bar 10 has been sliding in the short straight groove in the slide 9. After the steel pipe passes through the roller 18, the slide bar 10 enters the inclined groove in the slide 9. At this time, the slide bar 10 is squeezed and drives the rack 8 to move upward.

By controlling the motor 3 to drive the screw rod 11 to reverse, the steel pipe can be pushed back by the baffle 6, thereby achieving the purpose of reciprocating rolling of certain pipe sections of the steel pipe.

[0029] Embodiment 2

[0030] If there is a certain distance between the other end of the steel pipe and the baffle 6, the baffle 6 needs to move for a period of time before it can contact the steel pipe and push the steel pipe back. For steel pipes of different lengths, the distance between the other end of the steel pipe and the baffle 6 will not be different. The problem is solved by the following solution.

The user can adjust the position of the push plate 20 by screwing the threaded rod 19, thereby changing the distance between the push plate 20 and the push block 4, which is convenient for driving steel pipes of different lengths to move back and forth.

[0032] The baffle plate 6 is internally slidably connected to a limit rod 21, which is fixedly connected to the push plate 20. The push plate 20 is limited by the limit rod 21. When the user screws the threaded rod 19, the threaded rod 19 can drive the push plate 20 to move forward and backward, thereby adjusting the position of the push plate 20.

[0033] Usage steps of the utility model: When the stainless steel pipe cold rolling and calendering equipment is in use, when the baffle 6 rotates upward to a position perpendicular to the base 1, if there is still a certain distance between the baffle 6 itself and the other end of the steel pipe, the threaded rod 19 can be screwed to make the threaded rod 19 drive the push plate 20 to press against the steel pipe. At this time, as long as the motor 3 drives the screw rod 11 to reverse, the baffle 6 can drive the steel pipe to move back immediately through the threaded rod 19 and the push plate 20, which can improve the efficiency of the equipment in reciprocating rolling certain sections of the steel pipe.
