DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, not all embodiments of the application.

[0019] Examples of the described embodiments are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the application, and cannot be understood as a limitation of the application.

[0020] Embodiment one: please refer to Figures 1-14The application provides a technical scheme: an automatic extrusion forming device for seamless steel pipes, which comprises a device main body 1, a compression mold assembly 2 arranged in the device main body 1, a forming mechanism 3 fixedly connected to the compression mold assembly 2, a discharging clamp 6 fixedly connected to the device main body 1 and located at the forming mechanism 3, a feeding mechanism 4 arranged at the back of the device main body 1, and a cleaning mechanism 5 arranged at the bottom of the feeding mechanism 4. The feeding mechanism 4 comprises: A guide frame 401 arranged at the back of the device main body 1. A telescopic rod 402 fixedly connected to the back of the device main body 1 and fixedly connected to the top of the guide frame 401. A feeding clamp 403 arranged at the back of the device main body 1 and located at the back of the forming mechanism 3. A material positioning table 404 fixedly connected to the inside of the device main body 1 and located at the bottom of the feeding clamp 403.

[0021] The pipe is placed into the feeding mechanism 4, and the telescopic rod 402 is elongated, the pipe is lifted to the material positioning table 404 through the guide frame 401, and then the two ends of the pipe are clamped by the feeding clamp 403, the pipe is clamped by the feeding clamp 403 and sent into the forming mechanism 3 for extrusion forming, and the two ends of the formed pipe are clamped by the discharging clamp 6 and sent out of the forming mechanism 3.

[0022] When the pipe is formed, a corresponding mold needs to be used in cooperation, the forming mechanism 3 comprises an upper mold guide bottom plate 301 fixedly connected to the bottom of the compression mold assembly 2, a double-head double-station upper mold 302 movably connected to the bottom of the upper mold guide bottom plate 301, a lower mold guide bottom plate 304 fixedly connected to the inside of the device main body 1 and located at the bottom of the double-head double-station upper mold 302, a double-head double-station lower mold 303 movably connected to the top of the lower mold guide bottom plate 304, a rebound mechanism 305 arranged in the double-head double-station upper mold 302 and the double-head double-station lower mold 303, limit blocks arranged between the double-head double-station lower mold 303 and the lower mold guide bottom plate 304 and between the upper mold guide bottom plate 301 and the double-head double-station upper mold 302, and extrusion mechanisms 306 fixedly connected to the left and right sides of the upper mold guide bottom plate 301 in the device main body 1, so that different limit blocks can be replaced, the positions of the double-head double-station upper mold 302 and the double-head double-station lower mold 303 can be changed, and different pipe lengths can be adapted.

[0023] The feeding clamp 403 sends the pipe into the first station corresponding to the double-head double-station upper mold 302 and the double-head double-station lower mold 303, then the mold assembly 2 pushes the upper mold guide bottom plate 301, so that the double-head double-station upper mold 302 and the double-head double-station lower mold 303 fix the pipe, then the extrusion mechanism 306 extrudes the two ends of the pipe to make the pipe form, after extrusion, the extrusion mechanism 306 resets, the double-head double-station upper mold 302 is driven upward by the upper mold guide bottom plate 301, and the feeding clamp 403 clamps the two ends of the pipe, the pipe in the first station is sent into the second station, and the feeding clamp 403 sends a new pipe into the first station, then the mold assembly 2 pushes the double-head double-station upper mold 302 downward by the upper mold guide bottom plate 301 to fix the pipe, then the extrusion mechanism 306 extrudes the pipe in the second station again to form, after forming, the mold assembly 2 drives the double-head double-station upper mold 302 to move by the upper mold guide bottom plate 301, and the formed pipe is taken out from the inside of the forming mechanism 3 by the unloading clamp 6.

[0024] Before the pipe is sent into the forming mechanism 3 to be formed, the debris attached to the outer wall needs to be removed, so that the hard debris is not pressed into the surface of the metal pipe under high pressure when the pipe is clamped, causing permanent scratches, pits or indentations. The guide frame 401 is provided with a conveying belt 405, and the outer wall of the conveying belt 405 is fixedly connected with a pushing frame 406.

[0025] The pushing frame 406 is movably connected with a rolling rod 407, and the conveying belt 405 is fixedly connected with a plurality of protruding blocks 408.

[0026] The pipe is placed into the guide frame 401 from the back, and the pipe rolls down along the guide frame 401 to the top of the conveying belt 405. The conveying belt 405 pushes the metal pipe downward by the pushing frame 406. The rolling rod 407 in the pushing frame 406 can make the pipe roll in the pushing frame 406. When the pushing frame 406 pushes the pipe, the bottom of the pipe will be in contact with the guide frame 401, so that the pushing frame 406 pushes the metal pipe to rotate continuously. When the pipe rolls over the top of the protruding block 408, it will produce a jolting effect, which shakes off the metal debris attached to the outer wall of the pipe. The rotation is beneficial to throwing off the debris on the surface of the pipe by centrifugal force.

[0027] When the pipe is formed by the extrusion mechanism 306, the inner wall of the pipe will be affected by the extrusion of the extrusion mechanism 306 due to the cutting residual burrs. The inner wall of the pipe is formed. The guide frame 401 is provided with an elastic plate 409. One end of the elastic plate 409 is fixedly connected with the guide frame 401. The elastic plate 409 is movably connected with a rotating sleeve 411 inside. The outer wall of the elastic plate 409 is provided with teeth engaged with the rotating sleeve 411. The rotating sleeve 411 is fixedly connected with a hard brush 412 on the inner side. The rotating sleeve 411 is movably connected with a guide rod 410 through a bearing inside. The guide rod 410 is movably connected with a sliding block 413 at the top. The sliding block 413 is movably connected with a sliding rod 414 inside. The sliding rod 414 is fixedly connected to the outer wall of the guide frame 401. The sliding block 413 is fixedly connected with a first spring 415 at the back. The first spring 415 is fixedly connected with the sliding rod 414 at the back.

[0028] When the pipe rolls down from the guide frame 401, it will be centered under the guidance of the elastic plate 409. Then it is pushed down by the pusher frame 406 through the conveyor belt 405. The two ends of the pipe will push the guide rod 410 down through the slope of the guide rod 410. In the process of pushing the guide rod 410, the rotating sleeve 411 will be pushed synchronously. The rotating sleeve 411 will rotate the hard brush 412 under the action of the teeth on the outer wall of the elastic plate 409. The hard brush 412 rotates to brush the burrs on the pipe. At the same time, the pipe will rotate under the push of the pusher frame 406, further brushing the burrs on the pipe, to remove the burrs on the inner wall of the pipe, to avoid the influence of the burrs on the extrusion. As the pipe is continuously pushed, the guide rod 410 will be pushed along the elastic plate 409, and the elastic plate 409 will be deformed, and the guide rod 410 will pull the sliding block 413 to move along the sliding rod 414 and make the first spring 415 be pulled up. When the first spring 415 is pulled up to the point where it cannot be pulled up, the pipe is continuously pushed, which will push the elastic plate 409 outward through the slope on the guide rod 410 until the guide rod 410 is pushed out of the outer side of the pipe, so that the pipe moves to the front of the elastic plate 409. Then the guide rod 410 will reset the rotating sleeve 411 under the push of the first spring 415.

[0029] Embodiment two: please refer to Figures 1-16 On the basis of embodiment one, the application provides a technical solution: The inner wall of the pipe may enter some debris inside the pipe during cutting, which may affect the extrusion forming process and needs to be cleaned. The cleaning mechanism 5 includes a centralized box 501, which is arranged at the bottom of the device main body 1. The centralized box 501 is fixedly connected with a gas supply pipe 502 on the right side. The gas supply pipe 502 is fixedly connected with the guide frame 401 on the right side. The centralized box 501 is fixedly connected with an air suction pipe 503 on the left side. The air suction pipe 503 is fixedly connected with the guide frame 401 on the left side.

[0030] The fan motor 505 is fixedly connected inside the centralized box 501, and the blocking net 506 is fixedly connected inside the centralized box 501 and located at the left side of the fan motor 505.

[0031] The fan motor 505 pushes air to the right side, so that the air flow of the air supply pipe 502 blows outward, and the air suction pipe 503 generates an air flow. When the pipeline rolls to the bottom of the guide frame 401, the air supply pipe 502 and the air suction pipe 503 are located at both ends of the pipeline, respectively. The air flow of the air supply pipe 502 blows the debris inside the pipeline to the direction of the air suction pipe 503, and the air suction pipe 503 sucks the debris blown by the air supply pipe 502 into the centralized box 501. Then, the debris is intercepted by the blocking net 506 inside the centralized box 501, so as to clean the inside of the pipeline.

[0032] The pipeline is shaken synchronously when the pipeline is acted on by the air flow, so that the air flow can clean the debris inside the pipeline. The guide frame 401 is provided with the mounting box 504, the mounting box 504 is fixedly connected to the back of the device main body 1, the guide column 508 is fixedly connected inside the mounting box 504, the pushing protrusion 507 is fixedly connected to the back of the guide column 508, the second spring 509 is fixedly connected to the front of the pushing protrusion 507, and the second spring 509 is fixedly connected to the inner wall of the mounting box 504.

[0033] During the process that the telescopic rod 402 is stretched and the guide frame 401 is pushed upward, the guide frame 401 pushes the pipeline upward. During this process, the pipeline is pushed outward by the pushing protrusion 507. With the rising of the guide frame 401, the guide frame 401 pushes the pushing protrusion 507 backward, so that the pushing protrusion 507 moves into the mounting box 504 and the second spring 509 is compressed. The guide frame 401 rises and generates a force to push the pipeline into the mounting box 504 through the inclined surface. After the pushing protrusion 507 is pushed into the mounting box 504, the pipeline collides with the mounting box 504, so that the pipeline is shaken, thereby promoting the cleaning effect of the air flow on the inner wall of the pipeline. Then, the telescopic rod 402 is contracted to drive the guide frame 401 to move downward. During this process, the pushing protrusion 507 is pushed again, and a certain impact effect is generated during the process that the guide frame 401 pushes the pushing protrusion 507, so that the guide frame 401 is shaken. Since the guide frame 401 has an inclined surface, the protruding block 408 shakes the adhering objects on the outer wall of the metal pipe. The adhering objects move to the positions of the air supply pipe 502 and the air suction pipe 503 under the action of the shaking inclined surface, so that the adhering objects are pushed by the air flow and enter the centralized box 501, thereby collecting the adhering objects and avoiding the adhering objects from being reattached to the outer wall of the pipeline due to multiple processes.

[0034] The above merely describes preferred specific embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art, according to the technical solution and inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
