[0030] Furthermore, guide grooves are formed inside the upper tool clamp 27 and the lower tool clamp 271, the surface of the cutting knife 28 fits inside the guide grooves, cutting edges are arranged on the left and right sides inside the cutting knife 28, a gap is arranged between the bottom of the upper tool clamp 27 and the top of the lower tool clamp 271, the surface of the flat tube part 29 passes through the gap arranged between the bottom of the upper tool clamp 27 and the top of the lower tool clamp 271, so that the cutting knife 28 can complete one cutting each time it moves forward and backward, and the cutting speed of the flat tube part 29 can be increased, and the material structure of the equipment is less, which can reduce the decrease in the cutting speed caused by the excessive inertia of the flat tube cutting structure during the cutting of conventional equipment, and reduce the failure rate of part damage, and reduce the risk and trouble of maintenance and disassembly.
[0031] Embodiment 2
[0032] Refer to Figures 1-5 Based on Embodiment 1, the feeding mechanism 3 further includes a synchronous following servo motor 31. The synchronous following servo motor 31 is arranged on the left side of the guide rail 1. A synchronous following turntable 32 is fixedly connected to the top of the synchronous following servo motor 31. A synchronous following connecting piece 33 is rotatably connected to the top end of the synchronous following turntable 32. One end of the synchronous following connecting piece 33 is rotatably connected to a synchronous following cantilever 34. One end of the synchronous following cantilever 34 is rotatably connected to a rotating connecting piece 38. Both sides of the rotating connecting piece 38 are fixedly connected to the inner side of the guide seat 26. The bottom end of the guide seat 26 is fixedly connected to a support platform 37. The bottom end of the support platform 37 is fixedly connected to a slider 36. A guide bar 35 is slidably connected inside the slider 36. The bottom end of the guide bar 35 is fixedly connected to the top of the guide rail 1.
[0033] Furthermore, a chute is opened inside the slider 36, and the surface of the guide bar 35 is slidably connected to the inside of the chute. When the cutter 28 and the flat pipe fitting 29 reach a relatively static state, the cutting servo motor 21 drives the cutting turntable 22 and the cutting cantilever 23 to move and rotate at high speed to complete the cutting of the flat pipe, so as to further ensure the cutting operation of the flat pipe fitting 29 at high speed and efficiently.
[0034] During the actual operation process, when this device is used, when cutting the flat pipe, the flat pipe forming machine forms and feeds the flat pipe to the cutting device. The cutting servo motor 21 and the synchronous following servo motor 31 perform synchronous movement and have the same specifications, and can drive the cutting cantilever 23 and the synchronous following cantilever 34 to perform synchronous movement. Thus, when the synchronous following cantilever 34 pushes the rotating connecting piece 38 to reciprocate in the left-right direction, on the other side, the cutting cantilever 23 cooperates with the left support seat 24 to perform synchronous reciprocating movement in the left-right direction. Then, when cutting, the flat pipe fitting 29 is fed and passes through the cutting edge inside the cutter 28. Among them, the cutting cantilever 23 drives the left support seat 24 to move and drives the cutter 28 thereon to move back and forth and drives the cutting edge to perform the cutting operation on the surface of the flat pipe fitting 29, so as to cut the flat pipe fitting 29. When the cutter 28 returns during the reciprocating movement, the cutting edge on the other side of the cutter 28 continues to cut the surface of the flat pipe fitting 29, so that the cutter 28 completes one cutting for each forward and backward movement, and improves the cutting speed of the flat pipe fitting 29. Moreover, the equipment uses less material structure, can reduce the reduction of the cutting speed caused by the excessive inertia of the flat pipe cutting structure during the cutting of conventional equipment, and reduce the failure rate of part damage, and reduce the risk and trouble of maintenance and disassembly;
[0035] In addition, by controlling the rotational speed of the synchronous following servo motor 31 and cutting off the speed of the servo motor 21 to be equal to the feeding speed of the flat pipe fitting 29, when the cutter 28 and the flat pipe fitting 29 reach a relatively stationary state, the cutting servo motor 21 drives the cutting frustum 22 and the cutting cantilever 23 to move and rotate at high speed to complete the cutting of the flat pipe, so that the cutting operation of the flat pipe fitting 29 can be further ensured at high speed and efficiently.

Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.
