[0020] Specifically, a mobile frame 2 is installed on both sides of the feeding table 1, and an equipment plate 21 is installed in the middle of the mobile frame 2. Mobile plates 23 are arranged on the front and rear sides of the equipment plate 21. The mobile plates 23 on both sides are connected to the equipment plate 21 through a card plate column 211. Both sides of the equipment plate 21 are provided with an embedding groove 22. The card plate column 211 drives the mobile plates 23 on both sides to move up and down through a first motor 24 on the side. A connecting column 26 is connected below the mobile plate 23 on one side, and a cutting device 27 is connected below the connecting column 26. The cutting device 27 is specifically a cutting knife made of an alloy steel material. The alloy steel has a high crystalline structure and strong grain boundary bonding, and can cut cold-rolled tubes 4 of different thicknesses. Distance detectors 28 are arranged on both sides above the cutting device 27. The distance detector 28 is specifically an ultrasonic detector. The ultrasonic detector uses ultrasonic technology to emit ultrasonic waves on the outer wall of the cold-rolled tube 4, so that the equipment senses the cold-rolled tube 4. The distance detector 28 is located on both sides of the cold-rolled tube 4. When one side of the cold-rolled tube 4 is flush with the conveyor table 6, a driving machine 3 is provided at the bottom of each group of mobile racks 2. The driving machine 3 prompts the mobile rack 2 to move horizontally inside the groove of the feeding table 1. A distance measuring device is installed on one side of the driving machine 3 to measure the distance between the two groups of mobile racks 2, so as to quantitatively cut the cold-rolled tube 4 of a specified length, which is convenient for batch and fixed-distance production of cold-rolled steel tubes. At the same time, one end of the cold-rolled steel tube can be cut to keep the surface of the cold-rolled tube 4 smooth, which also reduces the process of later reprocessing of the cold-rolled steel tube.

[0021] Driving machines 3 are arranged on both sides below the feeding platform 1, one side of the driving machine 3 is directly connected to one side of the bottom of the moving frame 2, and cold-rolled tubes 4 are arranged side by side above the conveying platform 6, and both sides of the cold-rolled tubes 4 are sleeved with fixing rings 5; fixing blocks 51 are arranged on both sides of the fixing ring 5, and the fixing blocks 51 are located inside the groove above the conveying platform 6.

The cold-rolled steel pipe can be quantitatively cut through the distance measurement setting, and fixed rings 5 ​​are provided on both sides of the cold-rolled pipe 4. The fixed ring 5 is fixedly installed in the inside of the groove above the conveying platform 6 through the fixed blocks 51 on both sides. An automatic lock 53 and a detection device 54 are provided above the fixed ring 5. The detection device 54 is an infrared detector. The infrared detector detects that the inside of the fixed ring 5 will reflect or block the infrared light beam after entering the steel pipe. The detector detects the presence of the object by receiving the reflected infrared light or sensing the interruption of the light beam, and then triggers the control unit of the automatic lock 53 through the setting of signal processing and control logic. The cold-rolled pipe 4 is fixed through the setting of the automatic lock 53, which can prevent the cold-rolled pipe 4 from moving during the cutting process.

[0023] The efficient feeding mechanism for steel pipes includes: a conveying platform 6 installed above the feeding platform 1, plug plates 61 are fixedly arranged on both sides of the bottom of the conveying platform 6, a lifting rod 62 is movably connected to the lower left side of the conveying platform 6, and a switch 63 is arranged on the upper left side of the feeding platform 1, brakes 64 are arranged on both sides of the plug plate 61, and a groove is inlaid on the top of the conveying platform 6; a moving motor 52 is also arranged on one side of the plug plate 61, a plate groove is arranged below the plug plate 61, a mounting plate 65 is arranged above the lifting rod 62, a pulley 66 is arranged above the mounting plate 65, and the pulley 66 is located on both sides of the conveying platform 6; the bottom of the lifting rod 62 is connected to the upper left side of the feeding platform 1, and grooves are also inlaid on both sides of the feeding platform 1, and the clamp 7 is located outside the cold-rolled tube 4.

[0024] Specifically, a plug plate 61 is provided at the bottom of the conveying platform 6, and a moving motor 52 is provided on one side of the plug plate 61. When the conveying platform 6 moves, the moving motor 52 drives the conveying platform 6 to move horizontally above the feeding platform 1 through the setting of the plug plate 61, so that the entire conveying platform 6 is displaced. At the same time, a lifting rod 62 is movably connected to one side of the lower side of the conveying platform 6, and a hydraulic cylinder is laterally connected to the bottom of the lifting rod 62. The hydraulic cylinder is located inside the feeding platform 1. The interior of the hydraulic cylinder includes a piston and a cylinder body. The switch 63 is directly connected to one side of the hydraulic cylinder. The flow direction of the hydraulic oil inside the hydraulic cylinder is controlled by the setting of the switch 63, and the lifting rod 62 is lifted and lowered to realize activities such as lifting, so that one side of the conveying platform 6 is raised, and the raised conveying platform 6 has a certain slope, which is convenient for conveying the cold-rolled tube 4 above the conveying platform 6 and speeding up the transportation speed of the cold-rolled tube 4. After the conveying of the conveying platform 6 is completed, two sets of pulleys 66 are arranged on both sides of the lower side of the conveying platform 6.

One end of the brake 64 is connected to the plug plate 61. When the plug plate 61 moves horizontally with the conveying platform 6, a limiter is installed inside the brake 64. When the conveying platform 6 moves to a specific position, the brake 64 is triggered to stop, so that the conveying platform 6 is fixed above the feeding platform 1 to continue processing the steel pipe.

[0025] A clamper 7 is provided below the opposite surface of the movable plate 23, a connecting piece 71 is connected to the top of the clamper 7, connecting shafts 72 are movably installed on both sides of the connecting piece 71, the connecting shaft 72 and the top of the clamper 7 are movably connected, a piston rod 74 is movably provided in the middle of the top of the connecting piece 71, and a hydraulic cylinder 75 is installed above the piston rod 74, an infrared detector 73 is provided below the connecting piece 71, a gear 76 is movably installed inside the connecting piece 71, a second motor 78 is provided on both sides of the equipment plate 21, and a connecting rod 79 is connected between the second motor 78 and the card plate column 211.

[0026] A slide plate 8 is arranged inside the groove, and a roller 9 is movably arranged below the slide plate 8 .

[0027] Specifically, a hydraulic cylinder 75 is fixedly installed inside one side of the equipment plate 21, and a piston rod 74 and a connecting member 71 are movably connected below the hydraulic cylinder 75. Connecting shafts 72 are provided on both sides of the connecting member 71, and a gear 76 is provided inside the connecting shaft 72. The gear 76 and the connecting shaft 72 are coaxially connected. When the hydraulic cylinder 75 lifts the piston rod 74 up and down, the lifting and lowering of the piston rod 74 will drive the gear 76 to rotate. The rotating gear 76 is coaxially connected to the connecting shaft 72, so that the connecting shaft 72 rotates. The connecting shaft 72 is fixedly connected to the clamp 7. When the equipment rotates, the two clamps 7 can move in opposite directions. At the same time, the hydraulic cylinder 75 drives the equipment plate 21 to descend through the second motor 78, so that the entire equipment descends, which is convenient for the clamp 7 to clamp the cold-rolled tube 4. According to the setting of the infrared detector 73 below the connecting piece 71, the infrared detector 73 and the infrared detector of the detection device 54 have the same operating principle. The cold-rolled tube 4 below the clamp 7 can be sensed through the setting of the infrared detector 73. When the equipment senses the steel pipe, the hydraulic cylinder 75 drives the piston rod 74, the gear 76 and other equipment to drive the clamp 7 to close to the middle of the cold-rolled tube 4, fix the steel pipe, and facilitate the processing of the steel pipe.
