Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing technology, specifically to an automatic steel pipe cutting machine. Background Technology

[0002] In the metal processing industry, the traditional methods for cutting steel pipes, especially welded steel pipes, mostly rely on manual cutting tools or semi-automatic cutting equipment. While these methods can meet production needs to a certain extent, with the improvement of industry standards and the demands of technological advancements, traditional cutting methods have gradually revealed problems such as low precision and low efficiency. In recent years, with the advancement of sensor technology and computer control technology, automated cutting equipment has begun to be gradually applied to the field of steel pipe cutting, significantly improving cutting precision and work efficiency. Currently, the common steel pipe cutting technologies on the market mainly include flame cutting, laser cutting, and plasma cutting. Among them, flame cutting has a lower cost, but the cutting quality and speed are relatively poor; laser cutting has high precision, but the equipment investment cost is high; plasma cutting is somewhere in between.

[0003] In the existing technology for cutting steel pipes, after the steel pipe is cut, workers need to remove it and stack it. When the steel pipe is long, its weight will also increase, making it inconvenient for workers to handle. Usually, multiple people are needed to work together, resulting in low material cutting efficiency and high danger.

[0004] Therefore, it is necessary to invent an automatic steel pipe cutting machine to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic steel pipe cutting machine to solve the problem that when the steel pipe is long, its weight also increases, making it inconvenient for workers to handle. This usually requires multiple people to work together, resulting in low cutting efficiency and high risk.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic steel pipe cutting machine, including a cutting platform, a mounting frame that can slide left and right on the surface of the cutting platform, a cutting blade installed on the inner side of the mounting frame, a feeding bracket fixedly connected to the front side of the cutting platform, and a discharging mechanism fixedly connected to the rear side of the cutting platform. The discharging mechanism includes a discharging bracket, a second transmission roller, a second electric motor, a gantry frame, an infrared sensor, a transmission frame, a cylinder, a connecting plate, a limiting plate, a fixed shaft, a support roller, and a guide rod.

[0007] By adopting the above technical solution, the feeding bracket supports the front end of the steel pipe to be cut, pushes the mounting frame to the right, and the mounting frame slides the cutting blade to the right to cut the steel pipe. The cut steel pipe is then moved to the upper side of the conveyor frame by the discharge bracket. At this time, the support roller supports the lower side of the cut steel pipe. When the cylinder moves the support roller to the outside, the cut steel pipe will slide down from the inside of the conveyor frame. At this time, the receiving frame can be placed on the lower side of the conveyor frame to directly collect the cut steel pipe. Under the action of the guide rod, the steel pipe is neatly stacked on the upper side of the receiving frame, which improves the convenience and efficiency of unloading and improves the safety of workers.

[0008] Optionally, the inner side of the feeding bracket is rotatably connected to multiple sets of first transmission rollers, and a first electric motor is fixedly installed at the rear right end of the feeding bracket. The output end of the first electric motor is coaxially and fixedly connected to the rear first transmission roller.

[0009] By adopting the above technical solution, multiple sets of first transmission rollers support the uncut steel pipe, and the first electric motor drives the rear first transmission roller to rotate, thereby moving the uncut steel pipe to the rear.

[0010] Optionally, the discharge bracket is fixedly connected to the rear side of the cutting platform, and multiple sets of second transmission rollers are rotatably connected to the inner side of the discharge bracket. The second electric motor is fixedly installed at the rear right side of the discharge bracket, and the output end of the second electric motor is coaxially fixedly connected to the rear second transmission roller.

[0011] By adopting the above technical solution, the second transmission roller is used to support the cut steel pipe, and the output end of the second electric motor drives the rear second transmission roller to rotate, moving the cut steel pipe to the upper side of the transmission frame.

[0012] Optionally, the gantry frame is fixedly connected to the upper side of the rear end of the discharge support, and the infrared sensor is fixedly installed on the inner side of the gantry frame.

[0013] By adopting the above technical solution, the infrared sensor is used to monitor the cut steel pipe. After the rear end of the cut steel pipe overlaps the surface of the rear second transmission roller, the controller automatically starts the second electric motor to transport the steel pipe. After the front end of the cut steel pipe passes the rear second transmission roller, the second electric motor is automatically turned off.

[0014] Optionally, the transmission frame is fixedly connected to the rear end of the discharge bracket. Multiple sets of positioning holes are opened on both the left and right sides of the transmission frame. Opposite positioning frames are fixedly connected to the left and right sides of the transmission frame. The cylinder is fixedly installed on one side of the positioning frame. Multiple sets of guide rods are fixedly connected to the lower left side of the transmission frame. The guide rods are inclined.

[0015] Optionally, the connecting plate is slidably connected to the inner side of the positioning frame, the output end of the cylinder is fixedly connected to the middle of the connecting plate, multiple sets of limiting plates are fixedly connected to the surface of the connecting plate, and a fixed shaft is fixedly connected to the surface of the limiting plates on both the left and right sides that are close to each other, and the support roller is rotatably connected to the surface of the fixed shaft.

[0016] By adopting the above technical solution, the telescopic rod in the cylinder drives the connecting rod to slide inside the positioning frame, and then drives the fixed shaft to slide left and right inside the positioning hole through the limiting plate. The fixed shaft drives the support roller to slide left and right inside the positioning hole. During the movement of the cut steel pipe, the support roller supports the cut steel pipe. After the infrared sensor detects that the cut steel pipe has completely moved to the surface of the transmission frame, the controller starts the cylinders on both sides. The telescopic rod in the cylinder slides the support roller to both sides. At this time, the cut steel pipe slides down and slides to the inside of the receiving frame under the action of the guide rod.

[0017] Optionally, a first hydraulic cylinder is fixedly installed on the left side of the cutting platform, and the telescopic rod in the first hydraulic cylinder is fixedly connected to the left end of the mounting frame. Two sets of support plates are fixedly connected to the upper right side of the cutting platform, and a second hydraulic cylinder is fixedly installed on the upper surface of each of the two sets of support plates.

[0018] By adopting the above technical solution, during the cutting process, the mounting frame is pushed to the right by the telescopic rod in the first hydraulic cylinder, which in turn pushes the cutting blade to the right to cut the steel pipe.

[0019] Optionally, two sets of support blocks are fixedly connected to the right side of the upper surface of the cutting platform. A movable block is provided on the upper side of each set of support blocks. The lower end of the telescopic rod in the second hydraulic cylinder is fixedly connected to the movable block. A positioning mold is fixedly connected to the side surface of the movable block and the support block that are close to each other. A cutting seam is provided between the front and rear sets of support plates, movable blocks and support blocks.

[0020] By adopting the above technical solution, during the steel pipe cutting process, the telescopic rods in the two sets of second hydraulic cylinders push the movable block downwards, which cooperates with the fixed block to clamp and fix the steel pipe, thereby improving the stability of the steel pipe during the cutting process. In addition, the positioning molds on the inner side of the movable block and the support block can be replaced according to the outer diameter of the steel pipe.

[0021] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0022] 1. This utility model uses an infrared sensor to monitor the cut steel pipe, automatically moves the cut steel pipe to the upper side of the transmission frame, and moves the support roller outward by a cylinder. At this time, the cut steel pipe slides into the receiving frame through the guide rod, realizing automatic collection of the cut steel pipe, improving the convenience of operation, and improving the feeding speed and feeding safety.

[0023] 2. This utility model uses a second hydraulic cylinder, a movable block, and a support block to clamp and fix the steel pipe. The corresponding positioning mold can be selected according to the diameter of the steel pipe, so that the movable block and the support block can tightly fix the steel pipe, thereby improving the stability of the steel pipe cutting process.

Detailed Implementation

[0031] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0032] This utility model provides, for example Figures 1 to 3The automatic steel pipe cutting machine shown includes a cutting platform 1. A sliding mounting bracket 11 is provided on the surface of the cutting platform 1. A cutting blade 12 is mounted on the inner side of the mounting bracket 11. A first hydraulic cylinder 13 is fixedly mounted on the left side of the cutting platform 1. The telescopic rod of the first hydraulic cylinder 13 is fixedly connected to the left end of the mounting bracket 11. Two sets of support plates 14 are fixedly connected to the upper right side of the cutting platform 1. A second hydraulic cylinder 15 is fixedly mounted on the upper surface of each of the two sets of support plates 14. Two sets of support blocks 17 are fixedly connected to the right side of the upper surface of the cutting platform 1. The upper surfaces of the two sets of support blocks 17... A movable block 16 is provided. The lower end of the telescopic rod in the second hydraulic cylinder 15 is fixedly connected to the movable block 16. Positioning molds 18 are fixedly connected to the surfaces of the movable block 16 and the support block 17 that are close to each other. A cutting slit is provided between the front and rear support plates 14, the movable block 16 and the support block 17. A feeding bracket 2 is fixedly connected to the front side of the cutting platform 1. Multiple sets of first transmission rollers 21 are rotatably connected to the inner side of the feeding bracket 2. A first electric motor 22 is fixedly installed at the rear right side of the feeding bracket 2. The output end of the first electric motor 22 is coaxially fixedly connected to the rear first transmission roller 21.

[0033] The mounting bracket 11 has a drive mechanism on its side. The drive mechanism drives the cutting blade 12 to rotate at high speed to cut the steel pipe. During use, the steel pipe is placed on the upper side of the feeding bracket 2. At this time, multiple sets of first transmission rollers 21 support the uncut steel pipe. The output end of the first electric motor 22 drives the rear first transmission roller 21 to rotate. The rear first transmission roller 21 conveys the uncut steel pipe to the rear. After the uncut steel pipe is moved to the specified length, the first electric motor 21 stops rotating. At this time, the telescopic rods in the two sets of second hydraulic cylinders 15... The movable block 16 is pushed downwards to cooperate with the support block 17 and the two sets of positioning molds 18 to clamp and fix the uncut steel pipe. At this time, the first hydraulic cylinder 13 pushes the high-speed rotating cutting blade 12 to the right to cut the steel pipe. After cutting, the first hydraulic cylinder 13 drives the cutting blade 12 to reset. The second hydraulic cylinder 15 lifts the movable block 16 and the upper positioning mold 18 upwards. At this time, the first electric motor 22 restarts and drives the rear first transmission roller 22 to rotate and transport the uncut steel pipe in front to the rear. At the same time, the uncut steel pipe in front pushes the cut steel pipe in the rear to the rear.

[0034] participate Figure 1 , Figure 4 and Figure 5A material discharge mechanism is fixedly connected to the rear side of the cutting platform 1. The material discharge mechanism includes a material discharge bracket 3, a second transmission roller 31, a second electric motor 32, a gantry frame 33, an infrared sensor 34, a transmission frame 4, a cylinder 43, a connecting plate 44, a limiting plate 45, a fixed shaft 46, a support roller 47, and a guide rod 48. The material discharge bracket 3 is fixedly connected to the rear side of the cutting platform 1. Multiple sets of second transmission rollers 31 are rotatably connected to the inner side of the material discharge bracket 3. The second electric motor 32 is fixedly installed at the rear right side of the material discharge bracket 3. The output end of the second electric motor 32 is coaxially fixedly connected to the rear second transmission roller 31. The gantry frame 33 is fixedly connected to the upper side of the rear end of the material discharge bracket 3. The infrared sensor 34 is fixedly installed on... Inside the gantry 33, the transmission frame 4 is fixedly connected to the rear end of the discharge bracket 3. Multiple sets of positioning holes 41 are opened on both the left and right sides of the transmission frame 4. Positioning frames 42 are fixedly connected to the left and right sides of the transmission frame 4. The cylinder 43 is fixedly installed on the outer end of the positioning frame 42. Multiple sets of guide rods 48 are fixedly connected to the lower left side of the transmission frame 4. The guide rods 48 are inclined. The connecting plate 44 is slidably connected to the inner side of the positioning frame 42. The output end of the cylinder 43 is fixedly connected to the middle of the connecting plate 44. Multiple sets of limiting plates 45 are fixedly connected to the surface of the connecting plate 44. Fixed shafts 46 are fixedly connected to the surface of the limiting plates 45 on both the left and right sides that are close to each other. The support roller 47 is rotatably connected to the surface of the fixed shaft 46.

[0035] In addition, during the process of pushing the cut steel pipe backward from the uncut steel pipe, multiple sets of second drive rollers 31 inside the discharge bracket 3 support the cut steel pipe. Simultaneously, the infrared sensor 34 continuously monitors the surface of the rear-end second drive rollers 31. When the rear end of the cut steel pipe contacts the surface of the second drive rollers 31, the infrared sensor 34 transmits information to the controller, which automatically starts the second electric motor 32. The output of the second electric motor 32 drives the rear-end second drive rollers 31 to rotate, thus continuously conveying the cut steel pipe backward. Multiple sets of support rollers 47 on the surface of the transmission frame 4 support the cut steel pipe. When the front end of the cut steel pipe detaches from the surface of the rear second transmission roller 31, the infrared sensor 34 transmits information to the controller. The controller automatically shuts down the second electric motor 32 and starts the cylinder 43. The telescopic rod in the cylinder 43 moves the multiple sets of support rollers 47 outward through the cooperation of the connecting plate 44 and the fixed shaft 46. At this time, the lower end of the cut steel pipe lacks support and automatically slides down. Under the action of the guide rod 48, it slides down into the receiving frame, realizing the automatic unloading of the cut steel pipe.

[0036] The working principle of this utility model is as follows: After the equipment is started, the required steel pipe length parameters are first input through the human-machine interface. The control system calculates the cutting point position accordingly. The final output length of the steel pipe is customized according to the customer's needs. After the steel pipe is moved to the designated position, the cutting blade 12 cuts the steel pipe. Then the steel pipe is pushed to the rear. At this time, the infrared sensor 34 monitors the cut steel pipe and automatically moves the cut steel pipe to the upper side of the transmission frame 4. The support roller 47 is moved to the outside by the cylinder 43. At this time, the cut steel pipe slides into the receiving frame through the guide rod 48, realizing the automatic collection of the cut steel pipe, improving the convenience of operation, and improving the feeding speed and feeding safety.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
