Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing technology, specifically a sandblasting machine for processing plastic-coated composite steel pipes. Background Technology

[0002] In the processing of plastic-coated composite steel pipes, sandblasting is a crucial step, designed to remove impurities and oxide layers from the pipe surface, improve surface roughness, and provide a good adhesion base for subsequent plastic coating processes. However, existing sandblasting machines often face challenges in clamping and securing the steel pipes during processing.

[0003] Traditional sandblasting machines have clamping structures that are difficult to adapt to the processing needs of steel pipes of different specifications. For steel pipes with different inner diameters, they cannot achieve stable and precise clamping and fixing, which makes the steel pipes prone to shaking or displacement during sandblasting, affecting the sandblasting quality and even potentially causing damage to the steel pipe surface. Moreover, some clamping structures are complex to operate and cannot flexibly adjust the angle, making it difficult to meet the requirements of comprehensive sandblasting treatment of different parts of the steel pipe.

[0004] Furthermore, the recycling efficiency of the blasting medium during sandblasting is low, which not only increases production costs but may also cause some environmental pollution. Meanwhile, during the clamping process, there is a lack of effective monitoring methods for the clamping force, making it difficult to ensure that the steel pipe is firmly clamped without damaging it due to excessive clamping force. While existing technologies may already address these issues, this invention aims to provide an alternative or replacement solution. Utility Model Content

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a sandblasting machine for processing plastic-coated composite steel pipes, comprising: a processing box, a longitudinal and transverse lead screw module, a sandblaster, a raw material box, and an adjustable clamping structure. The longitudinal and transverse lead screw module is installed inside the processing box, the sandblaster is installed on the moving end of the longitudinal and transverse lead screw module, the raw material box is installed on the top of the processing box, and the sandblaster is connected to the raw material box. The adjustable clamping structure is installed on the processing box and includes: a pair of opposing telescopic shaft tubes, a pair of fitted gearboxes, a pair of angle drive motors, a pair of convex telescopic shaft rods, four pairs of convex telescopic sliders, a pair of circular electromagnets, a pair of circular magnets, multiple extended V-shaped rods, multiple concave bearing blocks, multiple horizontal telescopic blocks, multiple spider web telescopic blocks, multiple horizontal threaded tubes, a pair of horizontal telescopic threaded rods, and a pair of horizontal extended drive motors. A pair of opposing telescopic shaft tubes are respectively inserted parallel to each other into the inner side of the processing box. A pair of gearboxes are fitted onto the pair of opposing telescopic shaft tubes by pins. A pair of angle drive motors are respectively connected to the pair of gearboxes. A pair of convex telescopic shaft rods are respectively movably inserted into the pair of telescopic shaft tubes. Two pairs of convex telescopic grooves are respectively opened on the inner side of the pair of telescopic shaft tubes. Four pairs of convex telescopic sliders are respectively installed on the pair of convex telescopic shaft rods, and the four pairs of convex telescopic sliders are respectively movably inserted into the inner side of the four pairs of convex telescopic grooves. A pair of annular electromagnets are respectively installed on the pair of telescopic shaft tubes. A pair of annular magnets are respectively installed on the pair of convex telescopic shaft rods. The rod is provided with a spider web telescopic groove. Multiple horizontal telescopic sliders are movably inserted into the inner side of a pair of spider web telescopic grooves. Multiple concave bearing blocks are respectively installed on the pair of spider web telescopic grooves and the multiple horizontal telescopic sliders. Multiple extended V-shaped rods are respectively inserted into the multiple concave bearing blocks via shafts. Multiple spider web telescopic blocks are movably inserted into the inner side of a pair of spider web telescopic grooves. A pair of horizontal telescopic threaded rods are respectively inserted into the inner side of a pair of spider web telescopic grooves. Multiple horizontal threaded tubes are respectively inserted into the multiple spider web telescopic blocks, and multiple horizontal threaded tubes are movably fitted onto a pair of horizontal telescopic threaded rods. A pair of horizontal extension drive motor drive ends are respectively connected to a pair of horizontal telescopic threaded rods. It should be noted that, as described above, the operation of a pair of angle drive motors drives the gearboxes on their drive ends, which in turn drive a pair of opposing telescopic shafts to rotate vertically. The gearboxes and the opposing telescopic shafts are connected by pins. Energizing the annular electromagnets inside the opposing telescopic shafts causes magnetic repulsion between the electromagnets and the annular magnets on the convex telescopic shafts. These magnets then drive the convex telescopic shafts to extend and retract horizontally along the inner side of the opposing telescopic shafts. The convex telescopic shafts are inserted into the inner side of the steel pipe, and the... The horizontal expansion drive operates, driving the horizontal telescopic threaded rod on its drive end. This rod drives multiple horizontal threaded tubes, which in turn drive spiderweb telescopic blocks. These spiderweb telescopic blocks then drive the horizontal telescopic blocks, which in turn drive the concave bearing blocks on their surfaces. This changes the distance between the pairs of concave bearing blocks. Simultaneously, the pairs of concave bearing blocks drive the expansion V-shaped rods, which in turn expand and compress the inner side of the steel pipe. This achieves the goal of expanding, compressing, and fixing the inner side of the steel pipe after insertion and expansion.

[0006] Preferably, each of the plurality of extended V-shaped bars is provided with an extrusion strip.

[0007] Preferably, a circulator is provided on the inner side of the processing box.

[0008] Preferably, each of the pair of circular electromagnets is provided with a resistance regulator.

[0009] Preferably, each of the pair of convex telescopic shafts is provided with a sleeve spring.

[0010] Preferably, each of the plurality of extrusion strips is provided with a pressure sensor. Beneficial effects

[0011] This utility model provides a sandblasting machine for processing plastic-coated composite steel pipes. It offers the following advantages compared to existing technologies: A pair of angle-driven motors, transmitted through a gearbox, can drive the relative telescopic shaft tubes to rotate vertically, meeting processing requirements at different angles. When the circular electromagnet is energized, it generates magnetic repulsion against the circular magnet, causing the convex telescopic shaft rod to stably extend and retract horizontally within the relative telescopic shaft tube, allowing for smooth insertion into the steel pipe. Simultaneously, the horizontal expansion drive motor rotates the horizontal telescopic threaded rod, which in turn causes multiple horizontal threaded tubes to move the spiderweb telescopic blocks and the horizontal telescopic blocks, changing the spacing between the pairs of concave bearing blocks, thus expanding the V-shaped rod and expanding and compressing the inner side of the steel pipe for fixation. Furthermore, the extrusion strip on the expanding V-shaped rod increases friction and protects the steel pipe; the pressure sensor monitors the extrusion force in real time; the circulator facilitates the recovery of the sandblasting medium; the resistance regulator precisely controls the magnetic force of the circular electromagnet; and the geared spring provides buffer protection. These designs collectively ensure stable and precise clamping and fixation of the steel pipe, improving the quality and efficiency of sandblasting. Attached Figure Description
