[0002] According to the patent document with authorization announcement number "CN222999430U" and invention title "A Bending and Forming Device for Steel Pipes", the description states that: a flexible support plate is provided on the side of the first connecting rod, and a drive module is provided at one end of the transmission rod. In use, the steel pipe to be bent is first placed in the middle of the positioning assembly. By activating the drive module at one end of the transmission rod, the transmission rod is rotated counterclockwise. When the transmission rod rotates counterclockwise, it drives the second connecting rod to move through the first support plate. When the second connecting rod moves, it drives the first connecting rod to move. Through the cooperation of the first and second connecting rods, the first connecting rod expands outwards towards the first support plate. When the first connecting rod expands to a certain position, the flexible support plate on the side of the first connecting rod contacts the inner wall of the steel pipe, thereby positioning and initially clamping the steel pipe. This ensures that the outer surface of the steel pipe fits against the side of the inner wall of the bending mold, preventing the steel pipe from shifting during processing and causing damage. However, the following defects still exist:

[0003] Because of the high hardness of steel pipes, there is a large bending resistance when bending them, resulting in a slow bending speed and low bending efficiency. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example 1, by Figures 1-4 The present invention relates to a bending and forming device for steel pipe processing, including a processing table 1, with support legs 2 symmetrically installed at the bottom end of the processing table 1, and a bending limiting component 3 provided at the top of the processing table 1.

[0024] The bending limiting component 3 includes a bending disc 301 fixedly installed on the top of the processing table 1. A limiting arc groove 302 is opened in the circumferential direction of the bending disc 301. A heating coil 303 is installed inside the bending disc 301. The heating coil 303 is connected to a power supply device. After the heating coil 303 is energized, it can heat the steel pipe, so that the steel pipe can be softened and bendable. A bending drive component 4 is provided on the top of the processing table 1.

[0025] The bending drive assembly 4 includes a connecting plate 401 disposed above the processing table 1. Side arms 402 are symmetrically mounted at both ends of the connecting plate 401. A push column 407 is fixedly mounted on the top of the side arm 402 away from the connecting plate 401. A top plate 408 is mounted on the top of the push column 407. A steel pipe limiting member 409 is provided on the outside of the push column 407. A sliding block 404 is mounted on the bottom end of the connecting plate 401. A first sliding frame 403 is mounted on the bottom of the processing table 1. The sliding block 404 and the first sliding frame 403 are connected. The sliding connection has a first screw 405 rotatably mounted inside the first sliding frame 403. The first screw 405 is threadedly connected to the sliding block 404. One end of the first screw 405 is fixedly connected to the output shaft of the first motor 406. The first motor 406 is fixedly mounted on the first sliding frame 403. Two push columns 407 correspond to the two ends of the steel pipe. The bending disc 301 corresponds to the bending position of the steel pipe. When the push columns 407 move, they can push the two ends of the steel pipe to move and make the steel pipe bend along the limiting arc groove 302.

[0026] The steel pipe limiting component 409 includes two limiting plates 4091 sleeved on the outside of the push column 407. Through the bending disc 301, the two push columns 407, and the multiple limiting plates 4091, the steel pipe is limited and fixed, improving the stability of the steel pipe during heating. A pull block 4092 is provided on the side of the push column 407 near the connecting plate 401. Two connecting rods 4093 are symmetrically hinged to the ends of the pull block 4092. The ends of the two connecting rods 4093 are respectively hinged to the two limiting plates 4091. A second... The sliding frame 4094 and the pull block 4092 are slidably connected to the second sliding frame 4094. The second screw 4095 is rotatably installed inside the second sliding frame 4094. The second screw 4095 is threadedly connected to the pull block 4092. One end of the second screw 4095 is fixedly connected to the output shaft of the second motor 4096. The second motor 4096 is fixedly installed on the second sliding frame 4094. Two limit plates 4091 are provided on the push column 407. The two limit plates 4091 move closer to each other synchronously to facilitate clamping steel pipes of different diameters.

[0027] Working principle: First, the steel pipe to be processed is placed between the bending disc 301 and the two push columns 407. Then, the two second motors 4096 are turned on. After the second motors 4096 start, they drive the second screw 4095 to rotate. Since the second screw 4095 is threadedly connected to the pull block 4092, it drives the pull block 4092 to move away from the push column 407. Then, through the two connecting rods 4093, the two limiting plates 4091 move closer to each other, thereby clamping the steel pipe. This fixes the steel pipe with the bending disc 301, the two push columns 407, and the multiple limiting plates 4091.

[0028] Then, the heating coil 303 is energized, causing the limiting arc groove 302 to heat up. Since the bending disc 301 is in close contact with the steel pipe, the heat is transferred to the steel pipe, causing the steel pipe to soften at high temperature, making it easier to bend.

[0029] After the steel pipe reaches a certain temperature, the first motor 406 is turned on to drive the first screw 405 to rotate. Since the first screw 405 is threadedly connected to the sliding block 404, it pushes the connecting plate 401 to move towards the bending disc 301, so that the two pushing columns 407 squeeze both ends of the steel pipe, allowing the steel pipe to bend along the limiting arc groove 302. When the bending angle reaches the required value, the first motor 406 is stopped, and the connecting plate 401 stops moving. After the steel pipe cools down, it is unloaded.
