Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel pipe processing technology, and in particular to an adjustable high-frequency straight seam welded pipe length cutting device. Background Technology
[0002] With the continuous development of industrial modernization and the continuous improvement of infrastructure, the demand for steel pipes is constantly increasing. High-frequency welded pipes are widely used in industries such as construction, petroleum, chemical, machinery, and automobiles due to their advantages such as high production efficiency, good welding quality, and low cost. In practical applications, high-frequency welded pipes usually need to be cut into specific lengths to meet the needs of different scenarios. This puts higher demands on fixed-length pipe cutting equipment. However, when cutting welded pipes of different sizes, better equipment or devices are needed. Furthermore, if the powder generated during cutting is not cleaned in time, it will enter the inside of the device, affecting work efficiency and also dispersing the powder, polluting the environment.
[0003] Currently, in order to effectively apply the processing of straight seam welded pipes of various specifications and materials, and to meet the needs of modern industry for precise length cutting of welded pipes, ensure production efficiency and product quality, and effectively handle the powder generated during cutting, these have become problems that urgently need to be solved by those skilled in the art. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide an adjustable high-frequency straight seam welded pipe length cutting equipment, which can process straight seam welded pipes of various specifications and materials without changing the equipment, and can effectively handle the powder generated during cutting and perform targeted correction.
[0005] This utility model is achieved through the following technical solution:
[0006] An adjustable high-frequency straight seam welded pipe length cutting device includes a machine base, a cutting machine at the port of the machine base, a base on the front of the machine base, a worktable on the top of the base, limiting devices at both ends of the worktable, a moving cylinder inside the limiting device, a moving platform at the center of the moving cylinder, and a fixing device on the top of the moving platform.
[0007] As can be seen, in the above technical solution, the position of the welded pipe can be determined when it is transported in and out by the limiting device. The welded pipe is fixed under the cutting machine by the fixing device on the moving table. When it needs to be moved, one side can be fixed by moving the two moving tables. The required distance is moved to cut the pipe. The powder after cutting will fall into the collection tank under the sluice plate through the cutting groove.
[0008] Optionally, in one possible implementation, the base has an internal collection groove and an external cleaning port. The collection groove is trapezoidal in shape. It can be seen that in the above technical solution, the trapezoidal shape of the collection groove guides the powder collected at the top to the bottom, allowing for direct cleaning by opening the cleaning port, thus facilitating powder collection and subsequent cleaning.
[0009] Optionally, in one possible implementation, a strainer is provided on the top of the workbench, and the interior of the workbench communicates with the collection tank. It can be seen that in the above technical solution, the communication between the collection tank and the strainer allows all the powder falling from the cutting process after the moving platform moves to fall into the collection tank without requiring cleaning by personnel, thus improving work efficiency.
[0010] Optionally, in one possible implementation, the limiting device includes a fixed platform, a flip-top plate on top of the fixed platform, a rotating shaft at one end of the flip-top plate, a rubber ring at the bottom of the flip-top plate, and a through hole on the inner side of the rubber ring. It can be seen that in the above technical solution, when the welded pipe enters, it enters through the through hole in the rubber ring for initial fixing, and the cut welded pipe is placed on the same parallel line. The cut welded pipe exits from another limiting device on the same parallel line.
[0011] Optionally, in one possible implementation, both the top of the fixing platform and the bottom of the flip-top plate are provided with arc grooves, and a rubber ring is provided inside the arc grooves. The diameter of the through hole is the same as the outer diameter of the welded pipe. It can be seen that in the above technical solution, the flip-top plate and the fixing platform fix the rubber ring inside, and the rubber ring can be replaced according to different specifications of welded pipes, so that welded pipes of different specifications can be cut on the same device.
[0012] Optionally, in one possible implementation, the fixing device includes a motor, a push rod on one side of the motor, a clamping plate at the other end of the push rod, a fixing block on the inner side of the clamping plate, and a cutting groove at the center of the fixing block. It can be seen that in the above technical solution, the welded pipe is positioned on the fixing device, and the motor, through the push rod, clamps the clamping plate to the fixing block. The fixing block and the limiting device are on the same parallel line, achieving parallel clamping under fixed conditions, resulting in a smooth and consistent cut.
[0013] Optionally, in one possible implementation, the fixing devices are located on both sides of the top of the moving stage. The top of the moving stage has an arc-shaped groove of the same size as the fixing stage. The clamping plate is arc-shaped, and the clamping plate is connected to the fixing block by screws. The fixing block is semi-cylindrical, and the diameter of the hole on the inner side of the fixing block is the same as the diameter of the through hole on the limiting device. It can be seen that in the above technical solution, the fixing block can be replaced according to the size, just like the rubber ring, to ensure that cutting is performed under the same device, and the powder after cutting will enter the collection tank under the stencil through the reserved cutting groove.
[0014] The beneficial effects of this utility model are:
[0015] This utility model, through a limiting device and a fixing device, enables the cutting of welded pipes of different specifications and sizes to be carried out on the same device, and ensures the fixation and position determination during cutting, thus ensuring the flatness and consistency of the cut. It effectively solves the problem of processing straight seam welded pipes of various specifications and materials without changing equipment.
[0016] Meanwhile, the cutting machine uses a stencil and a collection trough to ensure that the powder after cutting enters the collection trough under the stencil through the pre-reserved cutting groove. When the machine needs to be moved, the powder after cutting will fall into the collection trough under the stencil through the cutting groove, which facilitates subsequent cleaning.

Therefore, they should not be construed as limitations on the utility model.
[0027] Example 1:
[0028] As shown in the figure, this embodiment provides an adjustable high-frequency straight seam welded pipe length cutting device, including a machine base 1, a cutting machine 2 at the port of the machine base 1, a base 3 on the front of the machine base 1, a worktable 4 on the top of the base 3, limiting devices 5 at both ends of the worktable 4, a moving cylinder 6 inside the limiting device 5, a moving platform 7 at the center of the moving cylinder 6, a fixing device 8 on the top of the moving platform 7, a collection trough 301 inside the base 3, a cleaning port 302 on the outside of the base 3, the collection trough 301 is shaped like a trapezoid, a strainer 401 on the top of the worktable 4, and the inside of the worktable 4 communicates with the collection trough 301.
[0029] As can be seen, in the above technical solution, the position of the welded pipe can be determined when it is transported in and out by the limiting device 5. The welded pipe is fixed under the cutting machine 2 by the fixing device 8 on the moving table 7. When it needs to be moved, one side can be fixed by moving the two moving tables 7. The required length of distance is moved to cut. The powder after cutting will fall into the collection tank 301 under the slot plate 401 through the cutting groove 805.
[0030] Furthermore, the cutting machine 2 can be replaced with compressed air cutting, using compressed air as a power source to drive the cutting tool. When the mechanical length-fixing mechanism triggers the cutting signal, the air valve is opened, causing the compressed air to push the cylinder piston, which in turn drives the cutting tool to fall quickly to complete the cutting action, thus avoiding the use of electric cutting equipment.
[0031] Usage: The collection tank 301 is tiered, which can guide the powder collected at the top to the bottom. This allows for direct cleaning by opening the cleaning port 302, which facilitates powder collection and subsequent cleaning. The collection tank 301 is connected to the stencil 401, so that the powder falling after the moving table 7 moves will fall into the collection tank 301 without the need for staff to clean it, thus improving work efficiency.
[0032] Example 2:
[0033] As shown in the figure, this embodiment provides an adjustable high-frequency straight seam welded pipe length cutting device, including a machine base 1, a cutting machine 2 at the port of the machine base 1, a base 3 on the front of the machine base 1, a worktable 4 on the top of the base 3, limiting devices 5 at both ends of the worktable 4, a moving cylinder 6 inside the limiting device 5, a moving platform 7 at the center of the moving cylinder 6, a fixing device 8 on the top of the moving platform 7, a collection trough 301 inside the base 3, and a cleaning port 302 on the outside of the base 3. The collection trough 301 is shaped like a trapezoid. A strainer 401 is provided on the top of the worktable 4, and the interior of the worktable 4 communicates with the collection trough 301. The limiting device 5 includes a fixing platform 501, a flip-top plate 502 on the top of the fixing platform 501, and a... The bottom of the end is provided with a rotating shaft 503, the bottom of the flip cover 502 is provided with a rubber ring 504, the inner side of the rubber ring 504 is provided with a through hole 505, the fixing device 8 includes a motor 801, one side of the motor 801 is provided with a push rod 802, the other end of the push rod 802 is provided with a clamping plate 803, the inner side of the clamping plate 803 is provided with a fixing block 804, the center of the fixing block 804 is provided with a cutting groove 805, the fixing device 8 is located on both sides of the top of the moving table 7, the top of the moving table 7 is provided with an arc groove of the same size as the fixing table 501, the clamping plate 803 is arc-shaped, the clamping plate 803 and the fixing block 804 are connected by screws, the fixing block 804 is semi-cylindrical, the inner diameter of the fixing block 804 is the same as the diameter of the through hole 505 on the limiting device 5.
[0034] As can be seen, in the above technical solution, the position of the welded pipe can be determined when it is transported in and out by the limiting device 5. The welded pipe is fixed under the cutting machine 2 by the fixing device 8 on the moving table 7. When it needs to be moved, one side can be fixed by moving the two moving tables 7. The required length of distance is moved to cut. The powder after cutting will fall into the collection tank 301 under the slot plate 401 through the cutting groove 805.
[0035] Usage: The collection tank 301 is trapezoidal, guiding the powder collected at the top to the bottom. This allows for direct cleaning by opening the cleaning port 302, facilitating powder collection and subsequent cleaning. The collection tank 301 is connected to the slot plate 401, ensuring that powder falling from the cutting process after the moving platform 7 moves falls into the collection tank 301 without requiring manual cleaning, thus improving work efficiency. When the welded pipe enters, it enters through the through hole 505 in the rubber ring 504 for initial fixation, ensuring the cut welded pipe is on the same parallel line. The finished welded pipe exits through another limiting device 5 on the same parallel line. The flip-top plate 502 and the fixed platform 501... Rubber ring 504 is fixed on the inside, and rubber ring 504 can be replaced according to different specifications and sizes of welded pipes, so that welded pipes of different specifications and sizes can be cut on the same device. The welded pipe is on the fixing device 8, and the clamping plate 803 clamps the fixing block 804 through the push rod 802 via the motor 801. The fixing block 804 and the limiting device 5 are on the same parallel line, so as to achieve parallel clamping under the fixed condition, making the cut surface flat and consistent. The fixing block 804 can be replaced according to the specifications and size, just like rubber ring 504, to ensure that cutting is carried out under the same device. After cutting, the powder will enter the collection tank 301 under the stencil plate 401 through the reserved cutting groove 805.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
