Description

Technical Field

[0001] This utility model belongs to the field of pushing device technology, specifically a pushing device for steel pipe forming. Background Technology

[0002] The pushing device for steel pipe forming is an indispensable piece of equipment in the manufacturing and processing of steel pipes. It is mainly used to push the steel pipe from its initial position to the processing or forming area. The pushing device for steel pipe forming is widely used in industries such as steel pipe manufacturing, processing, construction, and machinery. In steel pipe production lines, it is usually used in conjunction with other processing equipment (such as cutting machines, pipe bending machines, welding machines, etc.) to complete the forming and processing tasks of steel pipes. However, existing pushing devices cannot be adjusted according to the diameter of different steel pipes, making it inconvenient to push steel pipes of different diameters, thus limiting their applicability. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a pushing device for steel pipe forming, which effectively solves the problem that the existing pushing device cannot be adjusted according to the diameter of different steel pipes, is inconvenient to push steel pipes of different diameters, and has a limited scope of application.

Each of the four rectangular sliding rods has one end extending into the mounting ring and is fixedly mounted with a connecting frame. Each connecting frame has a roller mounted rotatably via a shaft. A first motor is fixedly mounted on one side of each of the four connecting frames, and the output end of each first motor extends into the connecting frame and is fixedly connected to the shaft. A second motor is fixedly mounted on the lower part of one side of the support frame. The output end of the second motor is equipped with a rotary transmission assembly, which is connected to the four rectangular sliding rods. The second motor outputs power to the four rectangular sliding rods through the rotary transmission assembly, allowing the four rectangular sliding rods to move and position the steel pipe according to its diameter.

[0005] Preferably, the rotary transmission assembly includes a gear, which is fixedly installed at the output end of the second motor. A shaft seat is rotatably installed on one side of the gear, and a positioning plate is fixedly installed at one end of the shaft seat. The bottom of the positioning plate is fixedly connected to the top of the support plate, and an external gear ring is meshed with the upper part of the gear.

[0006] Preferably, a positioning ring is fixedly installed on one side of the external gear ring, a positioning ring is provided on the surface of the positioning ring, a sliding ring is fixedly installed on the circumferential surface of the positioning ring, an annular groove is provided on the inner wall of the positioning ring, the sliding ring is slidably installed inside the annular groove, and six third support rods are fixedly installed at equal intervals in a ring on one side of the positioning ring, and one end of each third support rod is fixedly connected to the surface of the support ring.

[0007] Preferably, six second support rods are fixedly installed at equal intervals in a ring on the other side of the external gear ring, and a rotating ring is fixedly installed between one end of the six second support rods. Four pushing strips are fixedly installed at equal intervals in a ring on the inner wall of the rotating ring, and the four pushing strips are in close contact with four rectangular sliding rods.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: When in use, the operator inserts the steel pipe into the inside of the mounting ring, and then the operator starts the second motor on the support frame to drive the gear to rotate along the shaft seat on the positioning plate. When the gear rotates, it drives the outer gear ring to rotate. When the outer gear ring rotates, it drives the slip ring to rotate along the ring groove inside the positioning ring through the positioning ring, which increases the stability of the outer gear ring when rotating. When the outer gear ring rotates, it drives the rotating ring to rotate through the six second support rods.

[0009] When the rotating ring rotates, it drives four pushing bars to push four rectangular sliding rods along the inside of four rectangular sliding sleeves towards the steel pipe, while simultaneously compressing four springs. As the four rectangular sliding rods move, they drive rollers through connecting frames to position the steel pipe. Then, four first motors are started simultaneously. When the four first motors are running, they drive four rollers through four shafts, thereby moving the steel pipe. This allows the pushing device to be adjusted according to the diameter of different steel pipes, making it easy to push steel pipes of different diameters, thus expanding its application range.
