It is widely used in fields such as construction, machinery manufacturing, petrochemicals, water conservancy projects, and the automotive industry. Steel pipe straightening is a key process in steel pipe processing. It is mainly used to correct shape defects such as bending, twisting, and excessive ovality that occur in steel pipes during rolling, transportation, storage, or early processing, so that the steel pipes can be restored to straightness and roundness to meet the accuracy requirements of subsequent assembly, welding, or structural use.

[0003] Traditionally, during the straightening process of steel pipes, it is necessary to manually feed the steel pipes into the straightening equipment and manually push the steel pipes for auxiliary feeding operations. However, some steel pipes have a large degree of bending. During the manual pushing of the steel pipes for straightening operations, the bent steel pipes may bounce or deviate, which can easily cause injury to workers and poses a safety hazard.

[0004] Therefore, it is necessary to provide a new straightening device for steel pipe production to solve the above-mentioned technical problems. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0025] Please see Figures 1 to 5 This utility model provides a straightening device for steel pipe production. The straightening device for steel pipe production includes: a bracket 2, a support frame 1 fixedly installed at the bottom of the bracket 2, an upward-opening mounting groove 21 in the bracket 2, and a plurality of guide rollers 22 arranged laterally rotatably connected in the mounting groove 21, an inverted arc-shaped mounting frame 23 fixedly installed above each end of the bracket 2, and a transverse threaded rod 24 rotatably connected between the two arc-shaped mounting frames 23, a drive motor 25 fixedly installed at the end of one of the arc-shaped mounting frames 23, and the end of the threaded rod 24 fixedly connected to the output end of the drive motor 25, and a material-stopping structure 3 installed on the threaded rod 24.

[0026] It should be noted that the device in this utility model is placed at the feed inlet of the steel pipe straightening equipment. The support frame 1 supports the bracket 2. The operator places the steel pipe into the mounting groove 21 on the bracket 2. The retaining structure 3 is located at the end of the steel pipe. The drive motor 25 drives the threaded rod 24 to rotate, causing the retaining structure 3 to move towards the straightening equipment. The steel pipe is located on the guide roller 22. The steel pipe rolls on the guide roller 22, and the friction is small, which facilitates the movement of the steel pipe. The retaining structure 3 pushes the steel pipe to move until the steel pipe enters the straightening equipment for straightening. This utility model uses the drive motor 25 to drive the retaining structure 3 to move, thereby pushing the steel pipe into the straightening equipment for straightening. There is no need for manual labor to push the steel pipe, which can significantly reduce the intensity of manual operation and reduce physical consumption. At the same time, it reduces the direct contact between the human body and the feed inlet of the straightening equipment, reducing operational safety hazards.

[0027] The bracket 2 has multiple evenly distributed support frames 1 installed at its bottom. Each support frame 1 includes an arc-shaped support plate 11 fixedly installed at the bottom of the bracket 2. Two L-shaped support seats 12 are fixedly installed below the arc-shaped support plate 11. The support seats 12 have mounting holes 13 at their bottom. The support frame 1 is composed of an arc-shaped support plate 11 and two support seats 12, and the overall stability of the device is good.

[0028] Furthermore, the two support seats 12 are symmetrically distributed and fixedly installed at the bottom of the arc-shaped support plate 11 in a figure-eight shape; the figure-eight structure makes the connection between the support seat 12 and the arc-shaped support plate 11 form a triangular stable structure, which enhances the overall rigidity by utilizing the geometric stability of the triangle.

[0029] Furthermore, a reinforcing rib 14 is fixedly installed between the two support bases 12 near their bottom; this further improves the overall stability of the support frame 1.

[0030] In the embodiments of this utility model, please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5 The material blocking structure 3 includes a collar 31 sleeved on the threaded rod 24 and threadedly connected to the threaded rod 24. An arc-shaped stop block 32 is fixedly installed below the collar 31, and a baffle 33 is installed at the end of the arc-shaped stop block 32 away from the drive motor 25. The upper end of the baffle 33 is rotatably connected to the arc-shaped stop block 32 through a pin 34. A sliding rod 26 is fixedly installed between the two arc-shaped mounting brackets 23 and slides through the arc-shaped stop block 32.

[0031] It should be noted that: because the baffle 33 is rotatably connected to the rear side of the arc-shaped stop block 32, during the feeding process of the steel pipe, the steel pipe is directly fed into the mounting groove 21 by pressing against the baffle 33. The baffle 33 is pressed and flipped, and the steel pipe rolls along the guide roller 22 until it is completely moved onto the mounting groove 21. The baffle 33 needs to be a short distance away from the arc-shaped stop block 32. After the steel pipe is completely on the guide roller 22, the drive motor 25 drives the threaded rod 24 to move back a certain distance until the baffle 33 is detached from the steel pipe. Under its own weight, the baffle 33 falls down, and the drive motor 25 then drives the arc-shaped stop block 32 to move forward, carrying... The movable baffle 33 moves forward, pushing the steel pipe toward the straightening equipment for straightening. When feeding, this invention eliminates the need to move the baffle structure 3 first; the steel pipe can be directly pushed against the baffle 33. The baffle 33 automatically flips upward via the pin 34, creating an unobstructed passage. This eliminates the need for manual intervention to avoid the baffle 33, significantly lowering the operational threshold. After the steel pipe is placed, the drive motor 25 only needs to move the baffle 33 back a short distance, and the baffle 33 will naturally droop and reset under its own weight. No manual bending or calibration is required, reducing manual intervention and operational fatigue.

[0032] It is worth noting that two sliding rods 26 are fixedly installed between the two arc-shaped mounting brackets 23, and the two sliding rods 26 are symmetrically distributed and slidably connected to the arc-shaped stop block 32; the sliding connection surface between the two sliding rods 26 and the arc-shaped stop block 32 is larger, which can provide more stable support and guidance for the material blocking structure 3.

[0033] It is worth noting that the baffle 33 is fitted with the two slide bars 26 and the guide roller 22 with clearance; this ensures that the baffle 33 will not come into contact with other parts during natural verticality and flipping, and ensures that the baffle 33 flips smoothly.

[0034] Furthermore, two horizontal uprights 35 are fixedly installed on the side wall of the baffle 33 away from the arc-shaped stop block 32, and a set of arc-shaped stop bars 36 are fixedly installed on each of the two uprights 35. The arc-shaped stop bars 36 are installed on the baffle 33 through the uprights 35. When the baffle 33 pushes the steel pipe to move, the arc-shaped stop bars 36 will restrict the end of the steel pipe during the straightening process, so as to avoid the safety hazards caused by the end of the steel pipe swinging randomly due to its large bending amplitude during the straightening process, thus improving the safety of the device.

[0035] It is worth noting that the two sets of arc-shaped baffles 36 are symmetrically distributed, and the distance between the two sets of arc-shaped baffles 36 is greater than the maximum diameter of the threaded rod 24; this ensures that the arc-shaped baffles 36 will not collide with the threaded rod 24 during the flipping process of the baffle 33.

[0036] It is also worth noting that an acrylic transparent protective cover can be installed on the upper end of the arc-shaped mounting bracket 23 to shield the threaded rod 24 and prevent dust from falling onto it. Regular maintenance and cleaning of the threaded rod 24 are also required. A protective cover should also be installed on the drive motor 25 for its protection. The drive motor 25 can be a reversible AC motor from Dongfang Motor. Dongfang Motor's reversible AC motors are suitable for frequent bidirectional operation scenarios. In this device, it can be directly connected to an AC power supply, utilizing its reversible characteristics to achieve forward and reverse rotation of the motor, driving the threaded rod 24 to control the material-stopping structure 3, pushing the steel pipe to complete the straightening operation. Overheat protection ensures stable motor operation.

[0037] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
