An adjusting motor 43 for driving it to flip is provided on one side of the adjusting frame 45. The rotating part of the adjusting motor 43 is meshed and connected with the supporting end of the adjusting frame 45 through two bevel gears 44. The telescopic part of the hydraulic rod 41 is used to push the groove frame 42 up and down to adjust the cutting depth of the cutting blade 46 on the square pipe. At the same time, the rotating part of the adjusting motor 43 is used to drive the adjusting frame 45 to flip through the bevel gear 44, so as to adjust the inclination angle of the cutting blade 46 on the adjusting frame 45, and then the groove processing can be performed according to the actual groove size required.

[0031] In this embodiment: the conveying mechanism 3 includes a cylinder 31, a first center frame 32 is fixed to the telescopic part of the cylinder 31, a rack 37 is fixed to the lower side of the first center frame 32, a second center frame 33 is provided at the end of the rack 37 away from the first center frame 32, a driven gear 36 is rotatably connected inside the second center frame 33, the driven gear 36 is meshed with the rack 37, and a conveying assembly 35 for driving the square pipe to move is provided in the first center frame 32 and the second center frame 33, the conveying assembly 35 includes two conveying rollers 352, the outer side of the two conveying rollers 352 is covered with a conveying belt 351, the rotating shaft of the conveying roller 352 is fixedly connected to the output shaft of the first motor 34, and the second center frame 33 is provided with a notch at the position of the driven gear 36 , and the bottoms of the first center frame 32 and the second center frame 33 are attached to the bottom side of the frame 1, a T-shaped frame is fixed at the top position of the inner side of the frame 1, and a T-shaped slot for facilitating the sliding of the rack 37 is opened at the position of the rack 37 inside the frame 1. The telescopic part of the cylinder 31 is used to push the first center frame 32 to move, and the rack 37 is driven to slide in the T-shaped slot when the first center frame 32 moves, and then the second center frame 33 is driven to move in the opposite direction through the engagement of the rack 37 and the driven gear 36, and then the first center frame 32 and the second center frame 33 move in opposite directions, and then the square pipe is clamped and conveyed by the conveyor belt 351 and the conveyor roller 352 between the first center frame 32 and the second center frame 33.

[0032] In this embodiment: the moving mechanism 2 includes a moving screw 22, two moving screws 22 are rotatably connected to the upper side of the frame 1, the input end of the moving screw 22 is fixedly connected to the output shaft of the moving motor 21, and the moving frame 23 is slidably connected to the T-frame of the frame 1. The moving frame 23 is connected to the moving screw 22 through a threaded connection, and the rotating part of the moving motor 21 drives the moving screw 22 at its rear end to rotate synchronously, and then the moving frame 23 is driven by the moving screw 22 to move on the T-frame on the frame 1, and then the cutting and forming of the V-shaped groove is completed.

[0033] Working principle: When in use, first place the square pipe that needs to be grooved between the first center frame 32 and the second center frame 33. At this time, the telescopic part of the cylinder 31 pushes the first center frame 32 to move. At this time, the rack 37 moves backward under the drive of the first center frame 32. As the rack 37 meshes with the driven gear 36, the second center frame 33 moves forward along the T-slot of the frame 1, and then the two sets of conveyor belts 351 and conveyor rollers 352 between the first center frame 32 and the second center frame 33 clamp and fix the square pipe. Since the rack 37 and the driven gear 36 act synchronously, the entire square pipe will be clamped in the middle position of the frame 1.

[0034] The first motor 34 on the first center frame 32 drives the conveying roller 352 at its lower end to rotate, and then the conveying roller 352 in the first center frame 32 drives the conveying belt 351 to rotate. Since the square tube is clamped and fixed, when the conveying belt 351 in the first center frame 32 rotates, the conveying belt 351 and the conveying roller 352 in the second center frame 33 also rotate synchronously, and then the first motor 34 can accurately control the moving distance of the entire square tube.

[0035] When the square pipe is moved to the required groove position, first, the rotating part of the moving motor 21 drives the moving screw 22 to rotate, and the moving frame 23 is driven to move forward along the T-frame of the frame 1 through the rotation of the moving screw 22, and then the cutting blade 46 on the adjusting frame 45 is located at the moving position of the square pipe. At this time, the rotating part of the adjusting motor 43 can drive the bevel gear 44 to rotate, so that the adjusting frame 45 can flip the groove frame 42 to the required angle, and then the cutting blade 46 is driven by the cutting motor 47 to rotate at a high speed, and at the same time, the telescopic part of the hydraulic rod 41 pushes the groove frame 42 to move downward. When the cutting blade 46 moves to the required groove depth, the moving motor 21 rotates in the opposite direction, and then the moving frame 23 moves to the rear side, so as to cut one side of the groove of the square pipe; when the cutting blade 46 cuts through the square pipe, the adjusting motor 43 drives the adjusting frame 45 to rotate in the opposite direction by a corresponding angle through the bevel gear 44, and then the moving frame 23 moves forward again, and then the cutting on the other side of the groove is completed.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
