[0002] In the modern industrial field, the double-blade heavy-duty cutting machine has become the preferred tool for many manufacturers with its excellent performance and efficient productivity. This machine adopts an advanced double-blade design, which can perform fast and accurate cutting operations at the same time, greatly improving work efficiency. Its sturdy and durable structure and powerful power system enable it to easily cope with various difficult cutting tasks, whether it is ultra-thick pipes or hard metal materials. The double-blade heavy-duty cutting machine not only improves production efficiency, but also reduces the difficulty of operation and reduces labor costs.

[0003] A Chinese patent with publication number CN211891454U discloses a double-blade cutting machine, including a frame, on which a driving component, a driven component, a first reduction motor and a chain connected end to end are provided, the driving component and the driven component are respectively fixedly arranged at opposite ends of one side of the frame, the output shaft of the first reduction motor is fixedly connected to the driving component, the opposite ends of the chain are respectively sleeved on the driving component and the driven component, and a longitudinal moving mechanism is placed on the chain.

[0004] During the actual use and operation of the double-blade cutting machine in the above-mentioned prior art, we found that there are still some shortcomings. For example, although the traditional double-blade cutting machine has higher efficiency in cutting ultra-thick pipes, the spacing between the cutting discs on the cutting machine is not convenient for adjustment according to the processing requirements of the workpiece, so it is still relatively limited. Secondly, the cutting motor part of the traditional double-blade cutting machine often requires a large number of screw fasteners for installation in the disassembly and assembly structure. When electromechanical disassembly and assembly maintenance is required, maintenance personnel need to spend a lot of time to disassemble, which is very inconvenient. Utility Model Content
