Description

Technical Field

[0001] This utility model belongs to the field of hot-rolled steel pipe production technology, and in particular relates to a semi-automatic feeding device for sawing steel for hot-rolled steel pipe production. Background Technology

[0002] Hot-rolled steel pipe is a type of steel pipe product produced by high-temperature rolling. During its production and processing, it needs to be cut. Since steel pipes are generally heavy, manual feeding is very inconvenient. Therefore, it is often necessary to use corresponding feeding devices to assist in feeding, so as to facilitate subsequent processing of the steel pipe.

[0003] Chinese patent discloses a semi-automatic feeding device for hot-rolled steel pipe production, publication number CN223213337U. The paper states that it "includes a guide sleeve and two sets of support arms, which are slidably installed on the left and right sides of the guide sleeve; it also includes a drive device, a buffer device, a support device, two sets of electro-permanent magnets, two sets of first cylinders, and two sets of first push blocks. The drive device is installed inside the guide sleeve to drive the two sets of support arms to slide in opposite directions. The two sets of electro-permanent magnets are installed at the bottom of the two sets of support arms through the buffer device, which provides buffering for the two sets of electro-permanent magnets. The two sets of first cylinders are respectively installed on the outer side walls of the two sets of electro-permanent magnets. The two sets of first push blocks are respectively installed on the moving ends of the two sets of first cylinders. The guide sleeve is installed on the support device."

[0004] The above scheme uses two sets of horizontal electro-permanent magnets for magnetic feeding. However, when the steel pipe is not placed horizontally but tilted, one of the two sets of horizontal electro-permanent magnets will have a smaller contact area with the steel pipe, which will affect the stability of the steel pipe during lifting and transportation. In severe cases, the steel pipe may even fall off. Therefore, it is necessary to design a semi-automatic feeding device for hot-rolled steel pipe production. Utility Model Content

[0021] A preferred embodiment of the semi-automatic feeding device for hot-rolled steel pipe production provided by this utility model is, for example... Figures 1 to 5The following describes a semi-automatic feeding device for hot-rolled steel pipe production, comprising a traveling frame 2; a controller 10 fixedly connected to the lower end of one side of the traveling frame 2; a sliding plate 12 slidably connected inside the traveling frame 2; a fixed base 6 fixedly connected to the bottom end of the sliding plate 12; electromagnetic plates 7 fixedly connected at equal intervals to the bottom end of the fixed base 6; clamping plates 9 provided on both sides of the fixed base 6; and an electric winch 1 fixedly connected to the top end of the traveling frame 2. A steel cable on the electric winch 1 passes through the upper end of the traveling frame 2 and is fixed to the top end of the sliding plate 12. Fixed connection; movable component 8 mounted on fixed base 6, movable component 8 is used to realize the sliding adjustment of clamping plate 9; cylinder 14 is fixedly connected to the upper and lower ends of one side of clamping plate 9 respectively, the output end of cylinder 14 is fixedly connected to limit plate 11 respectively, the inner wall of limit plate 11 is provided with fixed plate 17, and one end of fixed plate 17 is fixedly connected to rubber pad 13; mounting component 5 is mounted on limit plate 11 and fixed plate 17, mounting component 5 is used to realize quick assembly and disassembly between fixed plate 17 and limit plate 11.

[0022] It should be noted that some existing semi-automatic feeding devices for hot-rolled steel pipe production still have certain shortcomings in actual use. They use two sets of horizontal electro-permanent magnets for magnetic feeding, but when the steel pipe is not placed horizontally and is tilted, one of the two sets of horizontal electro-permanent magnets will have a smaller contact area with the steel pipe, which will affect the stability of the steel pipe during lifting and transportation, and in severe cases, even cause the steel pipe to fall off.

[0023] In a further preferred embodiment of this utility model, the moving component 8 includes: a threaded rod 804 rotatably connected to the middle position of the inner wall of the fixed base 6, threaded plates 803 threadedly connected to both sides of the surface of the threaded rod 804, and connecting rods 802 fixedly connected to both ends of one side of the threaded plates 803, one end of the connecting rods 802 extending to the outside of the fixed base 6 and fixedly connected to the upper end of one side of the clamping plate 9; and a servo motor 801 fixedly connected to one side of the fixed base 6, the output end of the servo motor 801 being threadedly connected to one end of the threaded rod 804 via a coupling.

[0024] In a further preferred embodiment of the present invention, a sliding structure is formed between the threaded plate 803 and the interior of the fixed base 6, and one side of the threaded plate 803 and one end of the connecting rod 802 are welded together as an integrated structure.

[0025] In this embodiment, the servo motor 801 is started to drive the positive and negative threaded rods 804 to rotate, so that the threaded plate 803 slides and drives the connecting rod 802 to slide, thereby allowing the clamping plate 9 to slide, which facilitates clamping and fixing the two ends of steel pipes of different lengths.

[0026] In a further preferred embodiment of the present invention, the upper and lower ends of the clamping plate 9 are respectively provided with limiting holes 15, and one end of the limiting plate 11 is respectively fixedly connected with a limiting rod 16 that slides in cooperation with the inside of the limiting hole 15.

[0027] In this embodiment, the sliding between the limiting rod 16 and the inside of the limiting hole 15 is used to improve the stability of the back-and-forth sliding of the limiting plate 11. Example 2

[0028] Based on Example 1, a preferred embodiment of the semi-automatic feeding device for hot-rolled steel pipe production provided by this utility model is as follows: Figures 1 to 5 As shown: The mounting assembly 5 includes: a slot 508 formed on one side of the limiting plate 11, and a fixing groove 502 formed on one side of the limiting plate 11 between the slots 508; a sliding block 507 movably connected inside the fixing groove 502, one end of the sliding block 507 being fixedly connected to a sliding rod 506 extending to the outside of the limiting plate 11, one end of the sliding rod 506 being fixedly connected to an installation rod 501 extending into the slot 508, and an installation spring 505 wound around the surface of the sliding rod 506, with both ends of the installation spring 505 being fixedly connected to the inner wall of the fixing groove 502 and one end of the sliding block 507 respectively; and a locking plate 504 fixedly connected to one end of the fixing plate 17, with an installation hole 503 formed at one end of the locking plate 504.

[0029] In this embodiment, the engagement of the positive and negative threaded rod 804 with the slot 508, and the elastic force of the mounting spring 505, allows the mounting rod 501 to be engaged with or disengaged from the mounting hole 503, thereby enabling quick assembly and disassembly between the rubber pad 13, the fixing plate 17, and the limiting plate 11.

[0030] In a further preferred embodiment of the present invention, the mounting rod 501 is in the shape of an inverted U, and one end of the mounting rod 501 forms a locking structure with the interior of the mounting hole 503.

[0031] In this embodiment, the two locking plates 504 are simultaneously locked and fixed by the engagement of the inverted U-shaped mounting rod 501 with the inside of the mounting hole 503.

[0032] In a further preferred embodiment of the present invention, the card plate 504 and the card slot 508 form an engaging structure, and the shapes of the card plate 504 and the card slot 508 are inverted convex.

[0033] In this embodiment, the engagement between the inverted convex plate 504 and the slot 508 improves the stability of the initial engagement installation between the fixing plate 17 and the limiting plate 11.

[0034] In a further preferred embodiment of the present invention, a sliding structure is formed between the sliding block 507 and the interior of the fixing groove 502, and the shapes of the fixing groove 502 and the sliding block 507 are cross-shaped.

[0035] In this embodiment, the sliding stability of the slide rod 506 and the mounting rod 501 is improved by utilizing the sliding of the cross-shaped sliding block 507 and the inside of the fixing groove 502.

[0036] In a further preferred embodiment of the present invention, a groove 4 is provided on the inner wall of the walking frame 2, and sliders 3 that slide and cooperate with the inside of the groove 4 are fixedly connected to both sides of the sliding plate 12.

[0037] In this embodiment, the smoothness of the sliding plate 12 sliding up and down is improved by utilizing the sliding between the slider 3 and the inside of the groove 4.

[0038] In summary, firstly, by comparing the traveling device in the document or the existing crane traveling wheels, the traveling frame 2 is moved to the area where the steel pipe is to be placed. Then, by starting the servo motor 801 to drive the positive and negative threaded rod 804 to rotate, the threaded engagement between the positive and negative threaded rod 804 and the threaded plate 803 causes the threaded plate 803 to slide, thereby causing the connecting rod 802 to slide, and thus the clamping plate 9 can slide to the farthest distance. At the same time, the cylinder 14 is started to make the two limiting plates 11 extend to the maximum distance. The two limiting plates 11 have different heights and are respectively connected to the output ends of the two cylinders 14. Then, the operation of the electric winch 1 causes the sliding plate 12 to descend, which in turn causes the fixed seat 6 to descend, and the electromagnetic plate 7 to contact the surface of the steel pipe. Then, the servo motor 801 is started, which causes the clamping plate 9 to move closer to both ends of the steel pipe. Then, the cylinder 14 is started, which causes the limiting plate 11 to move towards the steel pipe. Then, the two rubber pads 13 limit and push the two ends of the steel pipe, so that the inclined steel pipe can be pushed horizontally and clamped. At the same time, the servo motor 801 is started, which causes the clamping plate 9 to clamp and fix the two ends of the steel pipe. Then, the electromagnetic plate 7 is powered to generate a suction force to magnetically fix the steel pipe. In this way, through multiple fixation, the firmness and stability of the lifting and loading of different steel pipes are improved. Then, start the electric winch 1 to raise the sliding plate 12 to facilitate the lifting of the steel pipe, and then move the traveling frame 2 to realize the lifting and loading of the steel pipe. When it moves to the designated position, use the electric winch 1 to lower the sliding plate 12 to drive the steel pipe down to the loading area. Then start the servo motor 801 and cylinder 14 to release the clamping and fixing of the steel pipe, and cut off the power to the electromagnetic plate 7 to release the clamping and fixing of the steel pipe. Furthermore, when the rubber pad 13 is severely worn and needs maintenance or replacement, the mounting rod 501 can be pulled to drive the sliding rod 506 and sliding block 507 to slide and compress the mounting spring 505 inside the fixing groove 502 until the mounting rod 501 slides completely out of the mounting hole 503. Then, the rubber pad 13 is pushed so that the clamping plate 504 slides completely out of the clamping groove 508, thereby enabling the disassembly of the fixing plate 17 and the limiting plate 11. During installation, the mounting rod 501 is first pulled to slide completely out of the clamping groove 508. Then, the clamping plate 504 is clamped into the clamping groove 508. The mounting rod 501 is then released, and the elastic force of the mounting spring 505 is used to make the mounting rod 501 slide into the mounting hole 503, thereby achieving a firm engagement between the clamping plate 504 and the clamping groove 508.
