[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 The present invention provides a pipe beveling machine, including a processing table 1, a placement groove 8 on the processing table 1, a cylinder 9 below the placement groove 8, a plurality of empty grooves 23 at the lower end of the cylinder 9, and a cutting assembly above the placement groove 8.

[0024] The cutting assembly includes a first lifting assembly 2, a motor 4, and a cutting blade 6;

[0025] The cylinder 9 is provided with multiple clamping components on its periphery. The clamping components include a fixed seat 11, a cover 12 and a clamping block 13. The multiple fixed seats 11 are fixed on the outer wall of the cylinder 9, and the cover 12 is fixed on the outer end of the cylinder 9. The cylinder 9 is provided with a cavity 14. Multiple springs 15 are symmetrically arranged inside the cavity 14. The clamping block 13 is inserted into the cavity 14 and connected to the front end of the springs 15. The rear end of the clamping block 13 is provided with a crossbar 16 that passes through the cover 12 and is slidably connected to the cover 12. The rear end of the crossbar 16 is provided with an arc surface 17. The lower end of the processing table 1 is provided with a control module 22 and a second lifting component 20. The output end of the second lifting component 20 is provided with a bent rod 21. The top end of the bent rod 21 is provided with a driving block 18 located outside the crossbar 16, and the driving block 18 is provided with an inclined surface 19 that contacts the arc surface 17.

[0026] The multiple clamping blocks 13 are the same size and are all isosceles trapezoidal structures.

[0027] The cover 12 is fixed to the outer end of the fixing base 11 by screws. The screw fixing method makes the cover 12 easy to assemble and makes the spring 15 in the cavity 14 easy to remove.

[0028] The first lifting component 2 is fixed on the upper end of the processing table 1, and the base 3 is fixed on one side of the motor 4. The base 3 is fixed to the output end of the first lifting component 2, and the cutter 6 is installed on the output end of the positioning seat 5.

[0029] Both the first lifting assembly 2 and the second lifting assembly 20 use hydraulic cylinders.

[0030] Pipeline loading and initial positioning:

[0031] Insert the cylindrical tube to be processed vertically through the placement slot 8 on the processing table 1, so that the bottom end of the tube naturally contacts the bottom of the cylinder 9.

[0032] During insertion, the outer wall of the pipe pushes multiple isosceles trapezoidal clamping blocks 13 distributed circumferentially to slide outward, thereby compressing the internal spring 15. The reaction force generated by the spring 15 is evenly applied to the outer wall of the pipe through the clamping blocks 13, so that the pipe is initially centered in the center of the cylinder 9.

[0033] Automatic centering and strong clamping:

[0034] The control module 22 activates the second lifting assembly 20, driving the bent rod 21 to move upward. The driving block 18 at the top of the bent rod 21 also moves upward. Its inclined surface 19 contacts the arc surface 17 at the rear end of the crossbar 16, generating a lateral force. This lateral force pushes the crossbar 16 to slide along the cover 12, causing the clamping block 13 to move further towards the center of the pipe, thereby achieving multi-directional synchronous clamping. Furthermore, the isosceles trapezoidal structure of the clamping block 13 ensures uniform clamping force in all directions, automatically and precisely fixing the pipe at the machining center position.

[0035] Beveling stage:

[0036] The first lifting component 2 drives the motor 4 and the cutter 6 to descend to the preset processing height. Then, the motor 4 drives the cutter 6 to rotate at high speed to perform annular cutting on the pipe port to form the required bevel angle. At the same time, the empty groove 23 at the lower end of the cylinder 9 provides a discharge channel for the chips, ensuring a clean and efficient processing process.

[0037] Unloading and resetting:

[0038] After processing is completed, the first lifting component 2 drives the cutter 6 to rise and reset, and the second lifting component 20 drives the bending rod 21 to descend, so that the driving block 18 and the crossbar 16 are disengaged. At this time, the spring 15 elastically resets and pushes the clamping block 13 to slide outward, releasing the constraint on the pipe and taking out the processed pipe, thus completing a single processing cycle.

[0039] In terms of processing efficiency, the fast spring 15 pre-positioning and hydraulic clamping system significantly shortens the clamping time for a single pipe, which is beneficial to improving the efficiency of batch processing. At the same time, the design of the slot 23 optimizes the chip discharge path, avoiding the processing interference problems caused by chip accumulation in traditional equipment.

[0040] The top of the cylinder 9 is provided with an annular positioning plate 10, which is fixed to the lower end of the processing table 1 by screws.

[0041] The way the annular positioning plate 10 is connected to the screws allows the cylinder 9 assembly to be quickly disassembled and replaced, facilitating maintenance and upgrades.

[0042] The output end of the motor 4 is provided with a positioning seat 5, and the positioning seat 5 is provided with a docking groove. One end of the cutter 6 is provided with a docking block 7 that is inserted into the docking groove, and the docking block 7 is fixed inside the docking groove by bolts.

[0043] In addition, the cutter 6 is bolted to the positioning seat 5 via the docking block 7, which supports quick replacement of cutters of different specifications and expands the processing range of the equipment.

[0044] From a cost-effectiveness perspective, a single set of equipment can meet the beveling needs of various pipe diameters, reducing the procurement costs for companies to use multiple specialized machines. Furthermore, the hydraulic drive system operates stably, reducing equipment failure rates, extending service life, and lowering maintenance costs.

[0045] In terms of operational safety, the fully enclosed clamping and cutting structure reduces the risk of operators coming into contact with moving parts. The integrated design of the control module 22 makes equipment operation simpler and reduces safety hazards caused by human error.

[0046] The control module 22 controls the first lifting assembly 2 and the second lifting assembly 20 based on automated control logic. This control method is common and efficient in modern industrial equipment. The control module 22 typically integrates a microprocessor, control circuits, and related software programs to achieve precise control of various components of the equipment.

[0047] After receiving the command, the control module 22's internal microprocessor calculates the action parameters that the first lifting component 2 (such as a hydraulic cylinder) needs to execute, including lifting speed and stroke distance, according to the program algorithm. Then, the control module 22 sends an electrical signal to the drive device (such as the hydraulic pump controller) of the first lifting component 2 through the control circuit. Upon receiving the signal, the drive device drives the hydraulic pump to operate, adjusting the flow and pressure of the hydraulic oil to extend or retract the piston rod of the hydraulic cylinder, thereby driving the motor 4 and the cutter 6 to rise or fall to the designated position. During this process, the position sensor installed on the first lifting component 2 monitors the position of the piston rod in real time and feeds the signal back to the control module 22. The control module 22 compares the actual position with the preset position; if there is a deviation, it promptly adjusts the electrical signal sent to the drive device to ensure that the cutter 6 accurately reaches the preset processing height.

[0048] The control principle of the second lifting component 20 is similar, but the function is different.
