[0002] Hydraulic flaring tools for mining composite pipes are key equipment for the installation of underground pipeline systems in mines. Their technological development is deeply intertwined with the demands of mining operations for pipeline reliability and installation efficiency. Currently, as mining operations move deeper into the mines, the complex underground environment places stringent requirements on the connection sealing and high-pressure resistance of mining composite pipes, while also leading to a diverse range of pipe specifications.

[0003] Similar products generally suffer from high reliance on manual labor, requiring manual handling of pipes, auxiliary positioning, and loading / unloading. This not only increases labor costs but also increases the risk of pipe damage due to operator fatigue. Furthermore, manual positioning accuracy is insufficient, often resulting in flaring position deviations and affecting processing quality. Adaptability is also poor; changing to pipes of different diameters and lengths requires adjusting the limiting structure with tools, and the extrusion head's adaptability is insufficient, making changeover adjustments time-consuming and hindering rapid response to multi-specification processing needs.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0018] Example Reference Figure 1-4 This is an embodiment of the present invention, which provides a hydraulic flaring tool for mining composite pipes, comprising: The conveying assembly 100 includes a support frame 101, a fixing block 102 fixedly connected to the inner wall of the support frame 101, a conveying gear 103 rotatably connected to the inner wall of the fixing block 102, a feed plate 104 fixedly connected to the side wall of the fixing block 102, a connecting sleeve 105 fixedly connected to the bottom of the feed plate 104, a double-ended lead screw 106 rotatably connected to the inner wall of the connecting sleeve 105, and a limiting plate 107 threadedly connected to the working surface of the double-ended lead screw 106. The fixing blocks 102 are symmetrically arranged on the side wall of the conveying gear 103. The flaring assembly 200 includes a fixed bracket 201 fixedly connected to the side wall of the support frame 101, a hydraulic push rod 202 adapted to be installed on the inner wall of the fixed bracket 201, an extrusion head 203 fixedly connected to the output end of the hydraulic push rod 202, and a support block 204 fixedly connected to the inner wall of the support frame 101. The flared assembly 200 also includes a tube 205 that is slidably connected to the top of the feed plate 104 and is movably connected to the working surface of the conveying gear 103.

[0019] Specifically, the support frame 101 is rectangular and serves to support the equipment. Multiple reinforcing ribs are provided at the connection points of the support frame 101. The fixing block 102 is fixedly connected to the top of the base plate of the support frame 101. The conveying gear 103 is rotatably connected between the two fixing blocks 102 and is responsible for transporting the single pipe 205 to the working area of ​​the flaring assembly 200. After flaring, the pipe 205 is transported out of the working area of ​​the flaring assembly 200. The feed plate 104 is fixed at a certain angle to the side wall of the fixing block 102. The angle and the weight of the pipe are used to move the pipe 205. The connecting sleeve 105 is fixed to the bottom of the feed plate 104. The double-ended screw 106 is rotatably connected to the inner wall of the connecting sleeve 105. The two ends of the double-ended screw 106 are reverse threads. The limiting plate 107, which is threadedly connected to the working surface of the double-ended screw 106, limits the rolling transport of the pipe 205. The fixed bracket 201 is fixed to the side of the support frame 101 by bolts to fix the hydraulic push rod 202. The extrusion head 203 fixed at the output end of the hydraulic push rod 202 performs the flaring operation on the pipe 205. The other end of the pipe 205 is provided with a support block 204, which is fixed to the inner wall of the support frame 101.

[0020] The conveying assembly 100 also includes a knob 108 fixedly connected to the end of the double-ended lead screw 106, and the knob 108 is symmetrically arranged at the end of the double-ended lead screw 106; Limiting plates 107 are symmetrically arranged at the ends of pipe 205, and double-headed screws 106 are equidistantly arranged at the bottom of feed plate 104.

[0021] Furthermore, to facilitate the adjustment of the limiting plate 107's position on the pipe 205, knobs 108 are fixedly connected to both ends of the double-ended lead screw 106 to facilitate its rotation. The three double-ended lead screws 106 together support the limiting plate 107, making the limiting plate 107's position on the pipe 205 more stable.

[0022] The conveying assembly 100 also includes a discharge plate 109 fixedly connected to the side wall of the fixed block 102, and a support leg 110 fixedly connected to the bottom of the discharge plate 109. The bottom of the feed plate 104 is fixedly connected to a support leg of the same specification as the support leg 110. The extrusion head 203 is inserted into the inner wall of the tube 205, and the tube 205 is slidably connected to the top of the discharge plate 109.

[0023] Preferably, the discharge plate 109 fixed to the side wall of the fixing block 102 is used to receive the processed pipe 205, and the bottom of the feed plate 104 and the discharge plate 109 are provided with support legs 110 to support them.

[0024] The conveying assembly 100 also includes a servo motor 111 adapted to be installed on the outer wall of the fixed block 102, and the output end of the servo motor 111 is fixedly connected to the side wall of the conveying gear 103.

[0025] It should be noted that a servo motor 111 is installed on the outer wall of the fixed block 102. The output end of the servo motor 111 is fixed to the side wall of the conveying gear 103. The worker controls the servo motor 111 to make the conveying gear 103 move the pipe 205 to a suitable position for hole enlargement operation.

[0026] During use, the operator rotates the knobs 108 at both ends of the double-ended lead screw 106 according to the specifications of the pipe 205 to be processed, thereby driving the double-ended lead screw 106 to rotate. Since the two ends of the double-ended lead screw 106 have reverse threads, the two sets of limiting plates 107 will move synchronously towards or in opposite directions along the screw axis until the distance between the two sets of limiting plates 107 matches the length of the pipe 205, completing the feed limit adjustment. The operator stacks the pipe 205 to be processed on the feed plate 104. Because the feed plate 104 is at an inclined angle, the pipe 205 rolls along the feed plate 104 towards the conveying gear 103 under its own gravity. Under the limiting action of the limiting plates 107, the pipe 205 always rolls along the preset trajectory, preventing deviation. When the pipe 205 rolls to the conveying gear 103, the teeth of the conveying gear 103 fit against the outer wall of the pipe. At this time, the operator controls the servo motor 111, which drives the conveying gear 103 to rotate at a preset speed and angle, thereby driving the pipe 205 to move along the axial direction and conveying the pipe 205 to the working area of ​​the flaring assembly 200 until one end of the pipe 205 is aligned with the support block 204. The operator operates the hydraulic push rod 202, whose output end pushes the extrusion head 203 to move towards the end of the pipe 205. After the extrusion head 203 is inserted into the inner wall of the pipe 205, the hydraulic push rod 202 continues to apply thrust, causing the end of the pipe 205 to undergo plastic deformation under the action of the extrusion head 203, gradually forming a flared structure that is consistent with the shape of the extrusion head 203. Once the flaring size reaches the preset requirement, the output end of the hydraulic push rod 202 drives the extrusion head 203 to retract in the opposite direction. The end of the tube 205 contacts the protruding part of the outer shell of the hydraulic push rod 202, causing the tube 205 to separate from the extrusion head 203, thus completing the flaring operation. The operator then restarts the servo motor 111, driving the conveying gear 103 to continue rotating, conveying the flared tube 205 from the flaring work area to the discharge plate 109. Under its own gravity, the tube 205 slides out of the equipment along the discharge plate 109.

[0027] In summary, the conveying component 100 eliminates the need for manual handling of pipes or auxiliary positioning, reducing labor costs and avoiding issues such as pipe collisions and positioning deviations that may occur during manual operation. It also enables batch processing, improving production efficiency. The knob 108 allows operators to quickly adjust the spacing of the limit plates 107 without tools. The stepped design of the extrusion head 203 allows the equipment to quickly adapt to pipes of different diameters and lengths, reducing equipment adjustment time. The feed plate 104 and discharge plate 109 utilize the pipe's own weight for automatic feeding and discharging. The conveying and flaring processes are seamless, requiring minimal manual intervention, reducing operator workload, and improving overall processing efficiency.
