Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a strip steel self-adaptive edge milling system. Background Art

[0002] In production lines such as large-diameter straight seam submerged arc welded steel pipes, it is necessary to automatically align the strip with the central axis of the milling machine and convey the strip forward to the milling machine for milling. The milling cutter head of the milling machine mills the two opposite long sides of the strip to obtain the precise plate width and edge shape required for welding.

[0003] However, in actual production processes, the milling amount varies for strips of different widths. Operators usually control the speed of the milling cutter disc according to the milling amount. When the milling amount is large, the milling cutter disc is controlled to run at a higher speed to improve processing efficiency. When the milling amount is small, the milling cutter disc is controlled to run at a lower speed to avoid aggravating the wear of the milling cutter disc due to excessive rotation speed and to increase the service life of the milling cutter disc. In this case, the accuracy of the milling cutter disc rotation speed is particularly important. Utility Model Content

[0026] The present invention will be described in further detail below based on the accompanying drawings and implementation examples.

[0027] In this specification, directional terms such as up, down, left, right, front, back, front, back, top, and bottom, which are mentioned or may be mentioned, are defined relative to the configurations shown in the accompanying drawings. The terms "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may vary depending on the location and usage of the component. Therefore, these or other directional terms should not be construed as restrictive.

[0028] This embodiment provides a strip steel adaptive edge milling system for performing edge milling on the strip steel. Figures 1-3 , including a milling machine 1, a distance measuring mechanism, two driving mechanisms and a monitoring mechanism, wherein the milling machine 1 includes two milling machines 1, the two milling machines 1 are arranged at intervals along the width direction of the strip a to be processed so that a storage space for accommodating the strip a to be processed is formed between the two, the milling machine 1 has a milling cutter disc 11 for rotating and cutting the strip a to be processed, the two driving mechanisms are respectively used to drive the two milling cutter discs 11 close to or away from the strip a to be processed, the distance measuring mechanism includes two distance measuring sensors 2, the two distance measuring sensors 2 are respectively used to measure the interval distance between the two milling cutter discs 11 and one side of the strip a to be processed, the monitoring mechanism includes two monitors 4, the two monitors 4 are respectively used to detect the rotation speed of the two milling cutter discs 11, and the milling machine 1, the driving mechanism, the distance measuring mechanism and the monitoring mechanism are all connected to the controller by electrical signals.

[0029] It should be noted that by using the distance measuring sensor 2 to measure the interval between the milling cutter disc 11 and one side of the strip a to be processed, the feed amount of the milling cutter disc 11 relative to the side of the strip a to be processed can be obtained. The feed amount of the milling cutter disc 11 to the strip a to be processed is determined by the distance the milling cutter disc 11 moves from the initial position to the side of the strip a to be processed. When the feed amount is large, the milling cutter disc 11 can be controlled to mill the strip at a larger rotation speed, thereby improving the processing efficiency. When the feed amount is small, the milling cutter disc 11 can be controlled to mill the strip a at a smaller rotation speed, thereby reducing the wear of the milling cutter disc 11 during cutting and milling, and improving the service life of the milling cutter disc 11.

[0030] In this embodiment, during processing, the distance between the milling cutter disc 11 and the moving side edge of the strip a to be processed is first detected by the distance measuring sensor 2, and then the driving mechanism drives the milling machine 1 to move toward the direction close to the strip a to be processed, so that the milling cutter disc 11 contacts the side edge of the strip a to be processed, thereby performing milling processing on the strip a to be processed. During this period, the milling cutter disc 11 is driven by the milling machine 1 to rotate, and its rotation speed is controlled by the controller. When the milling cutter disc 11 rotates, the monitor 4 monitors its rotation speed in real time, and feeds back the real-time rotation speed of the milling cutter disc 11 to the controller, so that the controller can monitor the actual rotation speed of the milling cutter disc 11, thereby enabling the controller to accurately control the rotation speed of the milling cutter disc 11.

[0031] In this embodiment, a distance measuring sensor 2 is used to measure the distance between the milling cutter disc 11 and one side of the strip a to be processed, so that the controller can accurately control the distance that the milling cutter disc 11 moves toward the strip a to be processed, thereby cutting out a strip that meets the width standard; a monitor 4 is used to monitor the rotation speed of the milling cutter disc 11 to ensure that the milling machine 1 can have a reasonable rotational cutting speed under the control of the controller, on the one hand to avoid the rotation speed of the milling cutter disc 11 being too slow and affecting the processing efficiency, and on the other hand to avoid the rotation speed of the milling cutter disc 11 being too fast and affecting the service life of the milling cutter disc 11.

[0032] In this embodiment, referring to Figure 3 The milling machine 1 includes a driver 13, a mounting plate 12 fixedly connected to the outer surface of the driver 13, and a rotating shaft 14. The rotating shaft 14 is connected to the milling cutter disc 11. The output end of the driver 13 is connected to the rotating shaft 14. When the driver 13 is working, it drives the rotating shaft 14 to rotate, and then drives the milling cutter disc 11 connected to the rotating shaft 14 to rotate. When the milling cutter disc 11 rotates, it contacts the side of the strip, thereby realizing cutting and milling of one side of the strip.

[0033] In this embodiment, the driver 13 is configured as a servo motor, which can adjust the rotation speed of the milling cutter head 11 under the control of the controller.

[0034] In this embodiment, a support plate is provided between the driving mechanism and the milling machine 1, the mounting plate is positioned on the support plate 51, and a guide rail assembly is provided under the support plate 51. The support plate 51 is slidably connected to the guide rail assembly, and the guide rail assembly is also used to support the support plate 51. The mounting plate 12 of the milling machine 1 is fixedly connected to the side of the support plate 51 close to the strip a to be processed, and the driving mechanism is used to drive the support plate 51 to slide on the guide rail assembly. The guide rail assembly here is used to carry and support the support plate 51 on the one hand, and on the other hand, it can ensure the accuracy of the moving direction of the milling machine 1.

[0035] In this embodiment, the slide rail assembly includes two guide rail members 52 arranged at relative intervals. The support plate 51 is slidably connected to the guide rail assembly through two sliding members. The sliding members are fixedly connected to the lower side of the support plate 51. The two sliding members are slidably connected to the two guide rail members 52 respectively. The guide rail members 52 here can be a structural form extending in the horizontal direction and protruding upward. The arrangement direction of the guide rail members 52 is set according to the actual moving direction. The sliding members here can adopt a structural form with a long strip-shaped bayonet recessed from bottom to top and embedded in the above-mentioned guide rail members 52.

[0036] In this embodiment, the driving mechanism includes a ball screw 32 and a rotating motor 31 for driving the ball screw 32 to rotate. The ball screw 32 is connected to the support plate 51 by a nut sleeve, and the ball screw 32 extends along the spacing direction between the milling cutter disc 11 and the strip steel a to be processed. When the driving mechanism is working, the rotating motor 31 is used to drive the ball screw 32 to rotate, driving the support plate 51 to move in a straight line, thereby making the milling machine 1 fixed on the support plate 51 approach or move away from the strip steel a to be processed.

[0037] In this embodiment, the monitor 4 is configured as an encoder, and the controller is configured as an industrial computer.

[0038] In this embodiment, referring to Figure 2 , Figure 2 The arrow in the figure points to the moving direction of the strip a to be processed. The distance sensor 2 and the milling cutter head 11 are arranged in sequence along the moving direction of the strip, and the height of the distance sensor 2 is consistent with the height of the milling cutter head 11 and the strip a to be processed. The distance sensor 2 here is set as a photoelectric sensor, and the electrical signal of the photoelectric sensor is connected to the controller.

However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the implementation cases of the present invention.
