Description

Technical Field

[0001] This utility model belongs to the field of steel pipe forming technology, and in particular relates to a steel pipe forming equipment. Background Technology

[0002] Gearboxes adjust the speed and torque output of motors through the meshing of multiple gears of different specifications to adapt to the working requirements of equipment. For example, planetary gearboxes have a sun gear, planet gears, and internal gear rings working together; while spur gearboxes rely on spur gears on parallel shafts for transmission.

[0003] For some gearbox housing structures, which are assembled from various parts, such as some cam-shaped hollow parts, the processing generally requires many steps. Therefore, we designed a steel pipe forming equipment that fits a steel pipe onto two cylindrical steel balls. One of the steel balls moves to pull the steel pipe into shape and form the required part size, thus achieving efficient processing. Utility Model Content

[0010] The beneficial effects of this utility model are: 1. This utility model places the steel pipe to be stretched on the surface of a fixed steel column and a movable steel column. Then, the push assembly drives the connector to move the movable steel column away from the fixed steel column. The cooperation between the movable steel column and the fixed steel column stretches the steel pipe into the required shape. This achieves the purpose of efficiently processing the steel pipe by placing it on two cylindrical steel balls and having one of the steel columns move to stretch the steel pipe into the required size of the part. 2. By using the guide rail and the sliding sleeve together, the sliding sleeve will slide on the surface of the guide rail during the movement of the threaded sleeve, providing guidance and limiting for the movement of the threaded sleeve, improving the stability of the movement of the threaded sleeve, and providing force support for the threaded sleeve, effectively preventing deformation of the bidirectional threaded rod. 3. This utility model uses the connecting steel plate, guide rail two and sliding sleeve two in cooperation. During the movement of the connecting column, the connecting steel plate is driven to move. The connecting steel plate then drives the sliding sleeve two to slide on the surface of the guide rail two, providing support for the movement of the connecting column, improving the bending resistance of the connecting column and making the connecting column less prone to deformation.

[0013] In the following description, embodiments of the steel pipe forming equipment of this utility model will be described with reference to the accompanying drawings.

[0014] Figure 1-4 This invention illustrates a steel pipe forming device according to an embodiment of the present invention. It includes a support platform 1, a fixed steel column 2 fixedly connected to the top of the support platform 1, and a movable steel column 3 provided on the top of the support platform 1. Forming parts 12 are fitted onto the surfaces of the fixed steel column 2 and the movable steel column 3. Bearing seats 10 are fixedly connected to the surfaces of both the fixed steel column 2 and the movable steel column 3, supporting the bottom of the forming parts 12. A connecting column 4 is fixedly connected to the bottom of the movable steel column 3, and the bottom of the connecting column 4 penetrates into the inner cavity of the support platform 1 and is fixedly connected to a connecting head 5. The top of the support platform 1 has a rectangular opening 11 for the connecting column 4 to move. A connecting steel plate 7 located on top of the support platform 1 is fixedly connected to the surface of the connecting column 4. Two symmetrical guide rails 8 are fixedly connected to the top of the support platform 1. Sliding sleeves 9 are slidably connected to the surface of the guide rails 8. The top of the sliding sleeves 9 is fixedly connected to the connecting steel plate 7. Through the cooperation of the connecting steel plate 7, the guide rails 8, and the sliding sleeves 9, the connecting steel plate 7 moves as the connecting column 4 moves, and the connecting steel plate 7 in turn moves the sliding sleeves 9 on the surface of the guide rails 8, thus providing a smooth path for the connecting column 4 to move. The support structure provides support and improves the bending resistance of the connecting column 4, making it less prone to deformation. A propulsion assembly 6 is provided between the connecting head 5 and the support platform 1. The propulsion assembly 6 includes two symmetrical diagonal braces 61 rotatably connected to the inner cavity of the connecting head 5 via a rotating shaft. A bidirectional threaded rod 62 is rotatably connected to the inner cavity of the support platform 1. Threaded sleeves 63 are threaded to both sides of the surface of the bidirectional threaded rod 62. The inner cavity of the threaded sleeve 63 is rotatably connected to the diagonal braces 61 via a rotating shaft. A motor 64 is fixedly installed on the outer side of the support platform 1. The output shaft of the motor 64 is connected to the bidirectional threaded rod 62. The threaded rod 62 is fixedly installed, and a guide rail 65 is fixedly installed on the top of the inner cavity of the support platform 1. A sliding sleeve 66 is fixedly installed on the top of the threaded sleeve 63. The sliding sleeve 66 is slidably connected to the surface of the guide rail 65. Through the cooperation of the guide rail 65 and the sliding sleeve 66, the sliding sleeve 66 will slide on the surface of the guide rail 65 during the movement of the threaded sleeve 63, providing guidance and limit for the movement of the threaded sleeve 63, improving the stability of the movement of the threaded sleeve 63, and providing force support for the threaded sleeve 63, effectively preventing the bidirectional threaded rod 62 from deforming.

[0015] Working principle: When using this utility model, the user places the steel pipe on the surface of the movable steel column 3 and the fixed steel column 2. During this process, the bearing seats 10 on the surface of the fixed steel column 2 and the movable steel column 3 will support the steel pipe and prevent the steel pipe from contacting the support platform 1. The steel pipe can be preheated to increase its ductility before stretching. Then, the motor 64 drives the bidirectional threaded rod 62 to rotate, causing the two threaded sleeves 63 to move towards each other. This causes the two diagonal braces 61 to push the connector 5 to move. The connector 5 then pushes the movable steel column 3 to move through the connecting column 4, stretching the steel pipe placed on the surface of the movable steel column 3 and the fixed steel column 2 until it is stretched into the desired shape.

[0016] In summary, this steel pipe forming equipment places the steel pipe to be stretched on the surfaces of the fixed steel column 2 and the movable steel column 3. Then, the push assembly 6 drives the connector 5 to move the movable steel column 3 away from the fixed steel column 2. The cooperation between the movable steel column 3 and the fixed steel column 2 stretches the steel pipe into the required shape. This achieves the goal of efficiently processing the steel pipe by placing it on two cylindrical steel balls and having one of the steel columns move to stretch the steel pipe into the required size of the part.
