Description

Technical Field

[0001] The present invention relates to the technical field of steel pipe cutting, and particularly to a deformation-preventing cutting device for thin-walled steel pipes. Background Art

[0002] The deformation-preventing cutting device for thin-walled steel pipes mainly stems from the deformation problem that thin-walled steel pipes are prone to during the cutting process. In the metal processing industry, especially in the production of thin-walled steel pipes, due to the thin wall thickness and fragile structure of the pipes, they are often affected by factors such as uneven heat and unbalanced cutting force during cutting, resulting in deformation or warping of the pipes, which affects the cutting accuracy and subsequent processing. This kind of deformation not only affects the product quality but also increases the scrap rate and raises the production cost.

[0003] The Chinese patent CN113618146B, authorized and announced on April 12, 2024, discloses a deformation-preventing cutting device for thin-walled steel pipes. Among them, it includes a support plate and a motor. The motor is fixedly installed on the side of the support plate. A power mechanism is fixedly installed on the side surface of the support plate. A rotating mechanism is sleeved on the outer surface of the power mechanism. A support sleeve is sleeved on the outer surface of the rotating mechanism. The support sleeve is fixedly connected to the support plate. A cutting mechanism is threadedly connected to the front end of the rotating mechanism.

[0004] In the above application document, by using an outer hoop sleeve for support, the possibility of deformation of the thin-walled steel pipe during cutting is reduced. However, when cutting thin-walled steel pipes, additional cutting fluid can be introduced to improve the cutting effect on the steel pipe and reduce the possibility of deformation. However, in the case of introducing cutting fluid, the sprayed cutting fluid makes the device have insufficient restraint on the steel pipe from the outside.

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] Embodiment 1, please refer to Figures 1-4 , a thin-walled steel pipe anti-deformation cutting device, including: Cutting chamber 100, inside which a protective fixture 200 is assembled; Fixed rod 300, which is assembled inside the cutting chamber 100. A moving rod 400 is assembled on the top of the fixed rod 300, and an internal pipe cutting disc 500 is assembled on the side of the moving rod 400. Insert the steel pipe into the protective fixture 200, and perform corresponding protective clamping operations on the steel pipe through the protective fixture 200. Enable the moving rod 400 driven by the electric telescopic rod and the internal pipe cutting disc 500 assembled on the moving rod 400, and the internal pipe cutting disc 500 can be driven to move upward a certain distance and perform corresponding cutting operations; On the side of the fixed rod 300, an air pressure chamber 601 is assembled. On the side of the cutting chamber 100, a penetrating infusion pipeline 602 is assembled. On the side of the infusion pipeline 602, a penetrating rotating shaft 605 is rotatably connected. On the outside of the rotating shaft 605, a stress plate 606 is fixedly connected. On the side of the protective fixture 200, a suction cup 608 is assembled. When the steel pipe is inserted into the protective fixture 200, the suction cup 608 can perform a preliminary adsorption operation on the steel pipe. On the side of the suction cup 608, a hose 609 is assembled. One end of the hose 609 away from the suction cup 608 is assembled at the side position of the air pressure chamber 601 and is communicated with the air pressure chamber 601. A transmission member for transmission is assembled between the air pressure chamber 601 and the stress plate 606. The transmission member includes a first transmission rod 603 assembled on the side of the moving rod 400. The first transmission rod 603 is located at the top of the air pressure chamber 601 and is slidably connected to the air pressure chamber 601 through a piston. On the side of the air pressure chamber 601, an arc rod 604 is slidably connected through a piston. When the moving rod 400 moves upward, it drives the first transmission rod 603 assembled on its side to move upward. Cooperating with the air pressure chamber 601 slidably connected to it through a piston, the gas originally stored in the air pressure chamber 601 can be pumped upward. The pressure in the air pressure chamber 601 then decreases, driving the arc rod 604 slidably connected to the air pressure chamber 601 to move, and the arc rod 604 slides into the air pressure chamber 601.

[0022] The stress plate 606 is located at the top of the arc rod 604 and is in a fixed state with the arc rod 604. An arc-shaped block 607 is fixedly connected to the side of the rotating shaft 605. When the arc rod 604 slides into the air pressure chamber 601, it drives the stress plate 606 fixedly connected to the arc rod 604 to rotate. As Figure 4 shown, the stress plate 606 rotates counterclockwise by ninety degrees, causing the stress plate 606 to drive the rotating shaft 605 fixedly connected to it to rotate. The rotating shaft 605 drives the arc-shaped block 607 fixedly connected to it to rotate counterclockwise by ninety degrees, and the originally closed infusion pipeline 602 can be opened to introduce cutting fluid to the cutting area. Moreover, when the pressure in the air pressure chamber 601 decreases, the pressure in the hose 609 communicated with the air pressure chamber 601 also decreases immediately. In this way, the residual gas between the suction cup 608 and the steel pipe can be extracted into the hose 609 through the hose 609. In this way, when the cutting fluid is sprayed, the adsorption effect of the suction cup 608 can be improved, and in this case, the stability during cutting is improved. After the cutting operation is completed, the moving rod 400 moves downward to complete the reset, facilitating the next use of the device.

[0023] During use, insert the steel pipe into the protective fixture 200. Through the protective fixture 200, corresponding protective clamping operations are performed on the steel pipe. The suction cup 608 assembled on the protective fixture 200 can perform preliminary adsorption operations on the steel pipe. Enable the moving rod 400 driven by the electric telescopic rod and the pipe internal cutting disc 500 assembled on the moving rod 400, which can drive the pipe internal cutting disc 500 to move upward a certain distance and perform corresponding cutting operations. At this time, the upward moving moving rod 400 drives the transmission rod one 603 assembled on its side to move upward. Cooperating with the air pressure chamber one 601 that is slidably connected to it through a piston, the gas originally stored in the air pressure chamber one 601 can be pumped upward. The pressure in the air pressure chamber one 601 then decreases, driving the arc-shaped rod 604 that is slidably connected to the air pressure chamber one 601 to move. The arc-shaped rod 604 slides into the air pressure chamber one 601, driving the force-bearing plate 606 fixedly connected to the arc-shaped rod 604 to rotate, so as to Figure 4 As shown, the force-bearing plate 606 rotates counterclockwise by ninety degrees, causing the force-bearing plate 606 to drive the rotating shaft 605 fixedly connected to it to rotate. The rotating shaft 605 drives the arc-shaped plug 607 fixedly connected to it to rotate counterclockwise by ninety degrees, and the originally closed infusion pipeline 602 can be opened to introduce cutting fluid to the cutting area. Moreover, when the pressure in the air pressure chamber one 601 decreases, the pressure in the flexible hose 609 connected to the air pressure chamber one 601 immediately decreases. In this way, the residual gas between the suction cup 608 and the steel pipe can be extracted into the flexible hose 609 through the flexible hose 609; after the cutting operation is completed, the moving rod 400 moves downward to complete the reset.

[0024] Example two, please refer to Figures 1-6 , on the basis of Example one, an auxiliary spray component 700 for rotating and spraying grinding fluid is assembled inside the cutting chamber 100. The auxiliary spray component 700 includes a bevel gear one 701 assembled on the side of the pipe internal cutting disc 500. The top of the fixed rod 300 is rotatably connected to a transmission rod two 702. The outer side of the transmission rod two 702 is fixedly connected with a bevel gear two 703 and a sprocket one 704 respectively. In the enabled state of the auxiliary spray component 700, the bevel gear two 703 and the bevel gear one 701 are in a meshing state. When the moving rod 400 moves upward and the pipe internal cutting disc 500 is in a rotating state, the bevel gear one 701 assembled on the side of the pipe internal cutting disc 500 moves upward to the meshing position with the bevel gear two 703. The pipe internal cutting disc 500 drives the bevel gear one 701 to rotate, causing the bevel gear one 701 to drive the meshing bevel gear two 703 to rotate. The bevel gear two 703 drives the transmission rod two 702 fixedly connected to it to rotate, causing the transmission rod two 702 to drive the sprocket one 704 fixedly connected to it to rotate.

[0025] A chain 705 is mounted on the outer side of the sprocket wheel 1 704, a pipe joint 706 is rotatably connected to the top of the liquid delivery pipe 602, a sprocket wheel 2 707 is fixedly connected to the outer side of the pipe joint 706, one end of the chain 705 away from the sprocket wheel 1 704 is mounted on the outer side of the sprocket wheel 2 707, a nozzle 708 is fixedly connected to the top of the pipe joint 706, a liquid reservoir 709 is mounted on the bottom of the cutting chamber 100, and a filter plate 710 is mounted between the liquid reservoir 709 and the cutting chamber 100. When the sprocket wheel 1 704 rotates, the chain 705 mounted on the outer side of the sprocket wheel 1 704 is matched to rotate the sprocket wheel 2 707 that is connected to the sprocket wheel 1 704 through the chain 705, and the sprocket wheel 2 707 drives the pipe joint 706 fixedly connected thereto to rotate, so that the pipe joint 706 drives the nozzle 708 fixedly connected thereto to rotate, and the cutting fluid in the liquid delivery pipe 602 is rotated and sprayed out, thereby increasing the coverage of the cutting fluid.

[0026] The used cutting fluid and the debris formed by cutting are filtered by the filter plate 710, and the cutting fluid flows into the liquid reservoir 709, thereby reducing the waste of cutting fluid.

[0027] When in use, on the basis of the first embodiment, when the moving rod 400 moves upward and the in-tube cutting disc 500 is in a rotating state, the bevel gear 1 701 assembled on the side of the in-tube cutting disc 500 moves upward to the meshing position with the bevel gear 2 703, and the in-tube cutting disc 500 drives the bevel gear 1 701 to rotate, so that the bevel gear 1 701 drives the bevel gear 2 703 meshing therewith to rotate, and the bevel gear 2 703 drives the transmission rod 2 702 fixedly connected thereto to rotate, so that the transmission rod 2 702 drives the transmission rod 2 702 fixed thereto to rotate. The connected sprocket 1 704 rotates, and cooperates with the chain 705 assembled on the outside of the sprocket 1 704, so that the sprocket 2 707 connected to the sprocket 1 704 through the chain 705 rotates, and the sprocket 2 707 drives the pipe joint 706 fixedly connected to it to rotate, so that the pipe joint 706 drives the nozzle 708 fixedly connected to it to rotate, and the cutting fluid in the infusion pipeline 602 is rotated and sprayed out, and the cutting fluid after use and the debris formed by cutting are filtered by the filter plate 710, and the cutting fluid flows into the liquid storage tank 709.

[0028] For example 3, please refer to Figures 1-8 On the basis of the first and second embodiments, a cleaning assembly 800 for cleaning debris is installed inside the cutting chamber 100, and the cleaning assembly 800 includes a movable rod 801, and a rotating rod 802 is rotatably connected to the movable rod 801, and a gear 803 is fixedly connected to the side of the rotating rod 802. The movable rod 801 driven by the electric telescopic rod is activated to make the movable rod 801 reciprocate in the horizontal direction, and the movable rod 801 then drives the rotating rod 802 rotatably connected thereto to reciprocate, so that the rotating rod 802 drives the gear 803 fixedly connected thereto to reciprocate in the horizontal direction.

[0029] On the side of the air pressure bin 601, an air pressure bin 804 connected to it is assembled. At the bottom of the air pressure bin 804, a connecting rod 805 is slidably connected through a piston. At the top of the connecting rod 805, a toothed rod 806 is fixedly connected. When the cleaning assembly 800 is in an enabled state, the toothed rod 806 is in a meshing state with the gear 803. A cleaning plate 807 is fixedly connected to the side of the rotating rod 802, and a receiving groove 808 is fixedly connected to the bottom of the filter plate 710. When the pressure in the air pressure bin 601 decreases, the pressure in the air pressure bin 804 connected to the air pressure bin 601 immediately decreases, driving the connecting rod 805 slidably connected to the air pressure bin 804 through the piston to move upward, causing the connecting rod 805 to drive the toothed rod 806 fixedly connected to it to move upward. At this time, the toothed rod 806 moves upward to the bottom position of the gear 803 and meshes with the gear 803, and the gear 803 reciprocates in the horizontal direction, causing the gear 803 to rotate during the movement. Then, the cleaning plate 807 can be driven by the rotating rod 802 to rotate during the reciprocating movement, sweeping the debris on the filter plate 710 into the receiving groove 808, making the cleaning plate 807 rotate during the cleaning process, and using both sides of the cleaning plate 807 to clean in turn, improving the cleaning effect of the device.

[0030] During use, on the basis of Embodiment 1 and Embodiment 2, the movable rod 801 driven by the electric telescopic rod is enabled, so that the movable rod 801 reciprocates in the horizontal direction. The movable rod 801 then drives the rotating rod 802 rotatably connected to it to reciprocate, causing the rotating rod 802 to drive the gear 803 fixedly connected to it to reciprocate in the horizontal direction. When the pressure in the air pressure bin 601 decreases, the pressure in the air pressure bin 804 connected to the air pressure bin 601 immediately decreases, driving the connecting rod 805 slidably connected to the air pressure bin 804 through the piston to move upward, causing the connecting rod 805 to drive the toothed rod 806 fixedly connected to it to move upward. At this time, the toothed rod 806 moves upward to the bottom position of the gear 803 and meshes with the gear 803, and the gear 803 reciprocates in the horizontal direction, causing the gear 803 to rotate during the movement. Then, the cleaning plate 807 can be driven by the rotating rod 802 to rotate during the reciprocating movement, sweeping the debris on the filter plate 710 into the receiving groove 808.
