However, in the current cutting equipment during use, each time only a single metal pipe can be fixed and then cut. After the pipe is cut, the worker cancels the fixation of the pipe, then removes the pipe, and then places a new pipe to be cut and fixes it again. The operation process is cumbersome, reducing the cutting efficiency of the pipe and increasing the labor burden of the workers. Content of the Utility Model
[0003] The utility model discloses a pipe cutting equipment, which solves the problems that the cutting equipment can only fix and cut a single pipe each time. After the pipe is cut, the worker cancels the fixation of the pipe, then removes the pipe, and the operation process is cumbersome, reducing the cutting efficiency of the pipe and increasing the labor burden of the workers.
[0004] To solve the above technical problems, the utility model specifically adopts the following technical solutions:
[0005] A pipe cutting equipment, including a workbench, a groove is opened on the top surface of the workbench, a group of first U-shaped plates are fixed at the bottom of the groove, an opening is opened at the bottom of the groove, a corresponding second U-shaped plate is arranged on one side of the first U-shaped plate, a connecting plate passing through the opening is fixed at the bottom of the second U-shaped plate, a first motor is fixed on the workbench, and a lead screw threadedly connected with the connecting plate is fixed on the rotating shaft of the first motor; a support plate is fixed on the top of the workbench, a second motor is arranged inside the support plate, a cutting blade corresponding to the inside of the first U-shaped plate is fixed on the rotating shaft of the second motor, an electric telescopic rod for driving the second motor to lift is arranged on the support plate, and a conveying unit with a conveying surface connected to the fixed end of the electric telescopic rod is fixed on the support plate.
[0006] Compared with the prior art, the utility model has the following beneficial effects:
[0007] After the staff can place multiple metal pipes on the workbench, make the ends of the pipes flush, then make the multiple pipes respectively contact a group of first U-shaped plates, and then start the first motor to rotate the lead screw. The lead screw can drive a group of connecting plates to move, so that a group of second U-shaped plates move along with it. When a second U-shaped plate approaches a first U-shaped plate, it can clamp the tube, completing the fixation of the pipe. A group of second U-shaped plates cooperate with a group of first U-shaped plates to complete the synchronous fixation of multiple pipes. The cutting disc corresponds to the inner sides of the first U-shaped plate and the second U-shaped plate.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0011] The following will describe in detail the specific content of the present utility model with reference to the drawings and embodiments.
[0012] As Figure 1 and Figure 2As shown in the figure, the utility model provides a pipe cutting device, which includes a workbench 1. A groove 2 is formed in the top surface of the workbench 1. A group of first U-shaped plates 21 are fixed to the bottom of the groove 2. An opening 22 is formed in the bottom of the groove 2. A corresponding second U-shaped plate 23 is arranged on one side of the first U-shaped plate 21. A connecting plate 24 passing through the opening 22 is fixed to the bottom of the second U-shaped plate 23. A first motor 25 is fixed on the workbench 1. A lead screw 26 threadedly connected to the connecting plate 24 is fixed to the rotating shaft of the first motor 25; A support plate 3 is fixed to the top of the workbench 1. A second motor 31 is arranged inside the support plate 3. A cutting blade 32 corresponding to the inside of the first U-shaped plate 21 is fixed to the rotating shaft of the second motor 31. An electric telescopic rod 34 for driving the second motor 31 to lift is arranged on the support plate 3. A conveying unit 33 with a conveying surface connected to the fixed end of the electric telescopic rod 34 is fixed to the support plate 3.
[0013] As Figure 1 shown, an automatic telescopic rod 5 is embedded on one side of the workbench 1. A positioning plate 51 is fixed to the telescopic end of the automatic telescopic rod 5. According to the length of the metal pipe 9, after starting the automatic telescopic rod 5, the position of the positioning plate 51 can be adjusted. So that when the metal pipe 9 is placed on the workbench 1, after one end of the metal pipe 9 contacts the positioning plate 51, the accurate positioning of the cutting position of the metal pipe 9 can be completed, and the cutting of the metal pipe 9 is located corresponding to the cutting blade 32; At the same time, the positioning plate 51 can also hold the end of the metal pipe 9 to increase the stability of the metal pipe 9.
[0014] As Figure 1 shown, the support plate 3 is arranged in an L shape. Two symmetrically arranged hydraulic rods 4 are arranged on the top of the support plate 3. A vertical rod 41 is fixed to the telescopic end of the hydraulic rod 4. A pressing plate 42 is fixed to the bottom end of the vertical rod 41; An opening is formed in the top of the support plate 3. The fixed end of the electric telescopic rod 34 is slidably connected in the opening. The top of the cutting blade 32 passes through the opening. A group of first U-shaped plates 21 and a group of second U-shaped plates 23 are arranged in a staggered front-back distribution (as Figure 2As shown in [Figure], a first U-shaped plate 21 and a second U-shaped plate 23 can complete the clamping and fixing of the metal pipe 9. After multiple metal pipes 9 are fixed by a group of first U-shaped plates 21 and a group of second U-shaped plates 23 respectively, the hydraulic rod 4 can be activated to drive the vertical rod 41 to move downward, and the pressing plate 42 can press the top surface of the metal pipe 9 to increase the stability of the metal pipe 9 placed on the workbench 1. The cutting blade 32 is located between the two pressing plates 42 and will not affect the normal lifting and lowering of the two pressing plates 42. The telescopic end of the electric telescopic rod 34 is fixed to the main body of the second motor 31. The conveying unit includes a driving motor, a driving roller, a driven roller, a conveyor belt and a frame. The frame is fixed on the top of the support plate 3. The driving roller and the driven roller are respectively rotatably connected to the inner side of the frame. The driving motor is fixed on the frame, and the rotating shaft of the driving motor is fixed to the end of the driving roller. The driving roller and the driven roller are connected by a conveyor belt. The fixed end of the electric telescopic rod 34 is fixed to the conveying surface of the conveyor belt. After the conveying unit 33 is started, the electric telescopic rod 34 can drive the cutting blade 32 to move through the second motor 31, so that the cutting blade 32 can sequentially move above multiple metal pipes 9.
[0015] As Figure 1 shown, the fixed end of the hydraulic rod 4 away from the positioning plate 51 penetrates through the support plate 3 and is fixed to the support plate 3. An opening in the shape of a straight line is formed on the side of the support plate 3 close to the positioning plate 51. The fixed end of the hydraulic rod 4 close to the positioning plate 51 is slidably connected in the through hole. The pressing plate 42 is arranged in an L shape, and the vertical surfaces of the two pressing plates 42 are close to each other. A connecting rod 52 connected to the positioning plate 51 is fixed to the fixed end of the hydraulic rod 4 close to the positioning plate 51. When the length of the metal pipe 9 is less than the distance from the left side to the right side of the workbench, the telescopic end of the hydraulic rod 4 away from the positioning plate 51 can be moved downward so that the bottom of the pressing plate 42 contacts the top of the workbench 1. At this time, after the staff places the metal pipe 9 on the workbench 1, one end of the metal pipe 9 can be made to contact the vertical surface of the pressing plate 42. Then the staff can activate the automatic telescopic rod 5 to drive the positioning plate 51 to drive the hydraulic rod 4 close to or away from the cutting blade 32 through the connecting rod 52, and then make the telescopic end of the hydraulic rod 4 extend downward so that the bottom of the pressing plate 42 contacts the top of the workbench 1. Subsequently, the position of the pressing plate 42 can be adjusted by activating the automatic telescopic rod 5 so that the vertical surface of the pressing plate 42 can resist the other end of the metal pipe 9 to complete the fixing of the metal pipe 9. Through the vertical surfaces of the two pressing plates 42, the two ends of multiple shorter metal pipes 9 can be effectively resisted to complete the fixing of the metal pipe 9.
[0016] As Figure 1 and Figure 2As shown, rubber pads 7 are fixed on the first U-shaped plate 21, the second U-shaped plate 23 and the pressing plate 42. The rubber pad 7 on the first U-shaped plate 21 is arranged on the back, the rubber pad 7 on the second U-shaped plate 23 is arranged on the front, and the rubber pad 7 on the pressing plate 42 is arranged at the bottom (in the orientation shown in Figure 1 ; rubber pads 7 can also be arranged on the vertical surface of the outer wall of the pressing plate 42). The arrangement of the rubber pads 7 can prevent the surface of the metal pipe 9 from being scratched when the first U-shaped plate 21, the second U-shaped plate 23 and the pressing plate 42 come into contact with the metal pipe 9, and can also increase the friction with the metal pipe 9.
[0017] As Figure 1 and Figure 2 shown, two symmetrically arranged legs are fixed at the bottom of the workbench 1, a bearing plate 8 is fixed between the two legs, and a collection box 81 corresponding to the groove 2 is placed on the bearing plate 8. A through hole is opened at the bottom of the groove 2. The debris generated during the cutting of the metal pipe 9 can be discharged into the collection box 81 through the opening 22 and the through hole at the bottom of the groove, so as to facilitate the subsequent centralized treatment of the debris by the staff.
[0018] As Figure 1 and Figure 2 shown, a baffle 6 is provided on the top of the workbench 1, a slideway 61 is opened on the top of the workbench 1, and the bottom of the baffle 6 is slidably connected in the slideway 61. The baffle 6 is made of a transparent plastic plate. After the metal pipe 9 is fixed, the staff can slide the baffle 6 to block the cutting part of the metal pipe 9, prevent the debris from splashing everywhere, and play a certain limiting effect on the debris.
[0019] During use, multiple metal pipes 9 can be placed on the workbench 1, the positions of the multiple metal pipes 9 can be adjusted so that the ends of the multiple metal pipes 9 are flush, and then the multiple metal pipes 9 are respectively brought into contact with the backs of a group of first U-shaped plates 21 (in the orientation shown in Figure 1 ). Then, after starting the first motor 25 (the first motor 25 uses a servo motor) to rotate the lead screw 26, a group of connecting plates 24 can be driven to move, so that a group of second U-shaped plates 23 approach a group of first U-shaped plates 21 respectively, and the fronts of a group of second U-shaped plates 23 (in the orientation shown in Figure 1The orientations shown in [description] are respectively in contact with a plurality of metal pipes 9 to complete the positioning and clamping fixation of the metal pipes 9; then start the second motor 31 to rotate the cutting blade 32, and then start the electric telescopic rod 34 to drive the second motor 31 to move downward. After the cutting blade 32 contacts the metal pipe 9, perform a cutting operation on the metal pipe 9. When a metal pipe 9 is cut, the electric telescopic rod 34 can be used to drive the second motor 31 to return to its original position, and then drive the conveying unit 33. After the electric telescopic rod 34 drives the cutting blade 32 to move towards the next metal pipe 9 through the second motor 31, a cutting operation can be performed on the next metal pipe 9.
