[0001] This utility model relates to the field of galvanized steel pipe processing technology, and in particular to a pipe body rounding device for galvanized steel pipe processing. Background Technology

[0002] During the production and processing of galvanized steel pipes, deformation such as bending and ellipticing can easily occur due to the effects of rolling, transportation, and storage, affecting subsequent connection installation and performance. This is particularly true in fields such as construction, water supply and drainage, and fire protection, where the roundness requirements for galvanized steel pipes are high. Deformed pipes may lead to problems such as poor joint sealing and increased fluid resistance. Therefore, specialized roundness correction equipment is needed to repair deformed galvanized steel pipes to ensure they meet usage standards.

[0003] To address the deformation issues that occur during the processing and use of galvanized steel pipes, the design of this pipe rounding device must meet the following requirements: First, it must be adaptable to galvanized steel pipes of different diameters and have a certain adjustment range; second, the rounding process must be precise, effectively restoring the roundness of the steel pipe and ensuring processing quality; third, operation must be convenient, enabling efficient processing and improving production efficiency; and fourth, the device must operate stably, ensuring good performance during long-term operation to meet the needs of industrialized mass production.

[0004] Therefore, we propose a pipe rounding device for processing galvanized steel pipes. Utility Model Content

Bolts are threaded inside the protruding plates. Four lugs are fixedly installed on the upper surface of the two fixing rings. Two sliding rods are fixedly installed on the side of the four lugs that are close to each other. Two sliders are slidably connected to the outside of the two sliding rods. A rounding component is installed on the lower surface of the two sliders. Moving components are installed on both sides of the bottom end of the two fixing rings.

[0007] As a further embodiment of this utility model: the rounding component includes a movable ring, the movable ring is fixedly installed on the lower surface of the two sliders, a housing is fixedly installed on the upper surface of the movable ring, a control switch is installed on the upper surface of the housing, a motor is fixedly installed on one side of the housing, and the motor is electrically connected to the control switch.

[0008] As a further embodiment of this utility model: a gear is rotatably connected inside the outer shell, a driven wheel is rotatably connected inside the movable ring, the driven wheel is meshed with the gear, two limiting blocks are fixedly installed on the side of the driven wheel away from the movable ring, a tool holder is slidably engaged inside the two limiting blocks, the tool holder has three adjustment holes, the tool holder is fixedly connected to the driven wheel by bolts, and a cutting tool is fixedly installed on the lower surface of the tool holder by bolts.

[0009] As a further embodiment of this utility model: the movable component includes two ear blocks, and four ear blocks are fixedly installed on both sides of the lower surface of the two fixed rings. Two threaded screws are rotatably connected to the four ear blocks on the side close to each other.

[0010] As a further embodiment of this utility model: two movable blocks are externally threaded to the two threaded screws, and the two movable blocks are respectively fixedly installed on both sides of the lower surface of the movable ring.

[0013] Compared with the prior art, this utility model provides a pipe rounding device for processing galvanized steel pipes, which has the following beneficial effects: 1. This utility model, the device adopts a structural design of double fixed rings and movable rings, which greatly improves the stability and accuracy of the rounding process. The eight convex plates can flexibly adjust the clamping force of the fixed rings on the steel pipe through bolts to adapt to the processing needs of different pipe diameters. At the same time, the tool holder in the rounding component is equipped with three adjustment holes, which can realize multi-level adjustment of the tool position by fixing it with the driven wheel through bolts. With the gear transmission structure driven by the motor, the steel pipe can be uniformly and efficiently rounded. This multi-dimensional adjustable design allows the device to maintain excellent rounding effect when facing galvanized steel pipes of various specifications and degrees of deformation.

[0014] 2. This utility model uses a servo motor to drive the threaded screw, causing the movable ring to slide smoothly on the slide bar, thus achieving precise control of the rounding position. The cooperation of the four lugs with the sprocket and chain ensures the synchronous operation of the two threaded screws, preventing the movable ring from shifting and affecting the rounding accuracy. In addition, the control switch integrates the operation of the motor and the servo motor, making it convenient to operate and enabling an automated rounding process. This significantly reduces the intensity of manual operation and improves processing efficiency. This design that combines automation and precision allows the device to perform stably in mass production and meet high-standard processing requirements.
