Description

Technical Field

[0001] The present invention relates to the technical field of metal pipe cutting devices, and specifically provides a metal pipe cutting device that prevents deformation. Background Art

[0002] A metal pipe cutting device is a piece of equipment specifically used for cutting metal pipes and is widely applied in fields such as industrial manufacturing, construction, pipe installation, and machining. Its core function is to precisely cut metal pipes into the required sizes or shapes through mechanical, thermal, or other technical means.

[0003] The patent with the publication number CN212599282U discloses a cutting device for metal part processing, which includes a motor. An output shaft is installed on one side of the motor. A second driving gear is arranged on the right part of the output shaft. The second driving gear is connected to a second driven gear and a fastening gear through a chain. A cutting blade is fixed on one side of the second driven gear. A fastening rod is fixed on one side of the fastening gear. A fastening spring is connected to the middle of the fastening rod. A first driving gear is installed on the left part of the output shaft. The first driving gear is connected to a first driven gear through an internal tooth rack. A transmission shaft is connected to one side of the first driven gear. A limiting cylinder is fixed on the right side of the fixing plate. The arrangement of the output shaft, the second driving gear, the second driven gear, and the fastening gear enables the cutting blade to rotate. The arrangement of the limiting ring, the transverse movement plate, and the fixing plate enables the cutting blade to perform a reciprocating movement up and down. Through the rotation and up-and-down movement of the cutting blade, the cutting blade automatically cuts the part to be cut. However, when the above device operates, it is difficult to prevent the pipe to be cut from deforming, which easily causes the pipe to deform, affecting the cutting angle of the pipe or the shape of the end face not meeting the design requirements, and requires secondary processing, increasing costs. Therefore, a metal pipe cutting device that prevents deformation is proposed to solve the above problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a metal pipe cutting device that prevents deformation in view of the deficiencies in the above-mentioned prior art.

[0005] To solve the above technical problems, the technical solution adopted by the present invention is: a metal pipe cutting device that prevents deformation, including a base. A pillar is fixedly connected to the top of the base. A cutting saw is installed at the top of the pillar. A rotary cutting mechanism is arranged on the top of the base. A clamping mechanism is arranged on the outer surface of the rotary cutting mechanism. A cleaning mechanism is arranged on the top of the base. The clamping mechanism includes: a hydraulic telescopic rod, an outer rod, a guide rod, an inner rod, a first clamping plate, a second clamping plate, a mounting plate, and a turntable. The mounting plate is fixedly connected to the top of the base. The turntable is rotatably connected to the inner wall of the mounting plate. The hydraulic telescopic rod is fixedly connected to the surface of the turntable. The outer rod is fixedly connected to the output end of the hydraulic telescopic rod. The inner rod is slidably connected to the inner wall of the outer rod. An elastic member is arranged inside the inner rod. The first clamping plate is fixedly connected to the end of the inner rod away from the hydraulic telescopic rod. The second clamping plate is hinged on the upper and lower sides of the first clamping plate. The guide rod is hinged on the upper and lower surfaces of the outer rod. The guide rod is hinged on the left side of the second clamping plate. The number of mounting plates is two, and the two mounting plates are symmetrically distributed on the top of the base, increasing the force-bearing area. After the contact area increases, the clamping force is evenly distributed over a larger area, preventing the deformation of the pipe fitting. After the area increases, it can also increase the friction force of the clamping plate on the pipe fitting to prevent the pipe fitting from slipping during subsequent rotation.

[0006] Preferably, the rotary cutting mechanism includes: a motor and a gear. The motor is fixedly connected to the front of the mounting plate. The gear is fixedly connected to the output end of the motor. The rotary cutting mechanism further includes: a guard plate, a hammer, and a push rod. The guard plate is fixedly connected between the two mounting plates. The hammer rotates on the surface of the mounting plate through a torsion spring. The push rod is fixedly connected to the surface of the mounting plate. The guard plate is made of a transparent material. The hammer contacts the guard plate. The gear meshes with the teeth on the circumferential surface of the turntable, which can reduce burrs. At the same time, when the cutting starts, the saw blade quickly feeds to half the depth of the pipe wall to complete the first-stage cutting, and the speed is reduced in the second stage to complete the remaining cutting, reducing stress concentration at the end section. With the rotation of the pipe fitting, the effect of preventing deformation can be achieved, and the uniformity and precision of the cut can also be improved. The hammer will strike the guard plate to vibrate off the metal chips splashed onto the surface, preventing the accumulation of metal chips from affecting the observation of the cutting process.

[0007] Preferably, the cleaning mechanism includes: a slider, a spring, a transmission rod, a first slide rail, a baffle, and a discharge port. The first slide rail is fixedly connected to the side of the mounting plate away from the hydraulic telescopic rod. The slider is slidably connected to the first slide rail. The spring is fixedly connected to the left side of the slider. The baffle is fixedly connected to the top of the slider. The transmission rod is fixedly connected to the bottom of the slider. The discharge port is opened on the surface of the base and the number of discharge ports is two. The cleaning mechanism further includes: a connecting plate, a scraping strip, a cylindrical brush, a friction wheel, and a second slide rail. The second slide rail is fixedly connected to the side of the mounting plate away from the hydraulic telescopic rod. The connecting plate is slidably connected to the outer wall of the second slide rail. The scraping strip is fixedly connected to the bottom of the connecting plate. The friction wheel is rotatably connected to the inner wall of the connecting plate. The cylindrical brush is fixedly connected to the axis of the friction wheel. The friction wheel contacts the top of the base and the surface of the base. The cylindrical brush contacts the surface of the base. The transmission rod is fixedly connected to the top of the connecting plate. The spring is fixedly connected to the side of the mounting plate away from the hydraulic telescopic rod. The baffle is located on the movement track of the push rod. The number of baffles is two, and the left baffle is located on the right side of the slider, preventing the accumulation of metal chips from affecting subsequent cutting operations, collecting and recycling the metal chips, reducing material waste, lowering production costs, and further polishing the metal chips adhered to the base by the rotation of the cylindrical brush to facilitate the subsequent cleaning by the scraping strip, improving the cleaning effect, preventing the tightly adhered metal chips from damaging the scraping strip, reducing the replacement frequency, enhancing the durability of the device, and lowering the maintenance cost.

[0008] Adopting the above technical solutions, the present invention can bring the following beneficial effects: 1. For the metal pipe cutting device with anti-deformation function, through the mutual cooperation among the hydraulic telescopic rod, the outer rod, the guiding rod, the inner rod, the first clamping plate, and the second clamping plate, the clamping of multiple clamping plates can be realized, the force-bearing area is increased. After the contact area is increased, the clamping force is evenly distributed in a larger area, preventing the deformation of the pipe fitting. After the area is increased, the friction force between the clamping plate and the pipe fitting can also be increased to prevent the pipe fitting from slipping during subsequent rotation.

[0009] 2. For the metal pipe cutting device with anti-deformation function, through the mutual cooperation among the mounting plate, the turntable, the motor, the gear, the guard plate, the knocking block, and the push rod, the rotation direction of the pipe fitting can be made opposite to the feeding direction of the saw blade, reducing the burrs generated during cutting. At the same time, when the cutting starts, the saw blade quickly feeds to half the depth of the pipe wall to complete the first-stage cutting, and the speed is reduced in the second stage to complete the remaining cutting, reducing the stress concentration at the end section. With the rotation of the pipe fitting, the anti-deformation effect can be achieved, the cutting accuracy can be improved, and the metal chips splashed onto the surface can be shaken off by the knocking hammer knocking the guard plate, preventing the accumulation of metal chips from affecting the observation of the cutting process.

[0010] 3.

[0013] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0014] Please refer to Figures 1-9 , an embodiment of the present invention is: a metal pipe cutting device for preventing deformation, including a base 1, a support column 2 fixedly connected to the top of the base 1, a cutting saw 3 installed on the top of the support column 2, a rotary cutting mechanism 5 arranged on the top of the base 1, a clamping mechanism 4 arranged on the outer surface of the rotary cutting mechanism 5, and a cleaning mechanism 6 arranged on the top of the base 1. The clamping mechanism 4 includes: a hydraulic telescopic rod 401, an outer rod 402, a guide rod 403, an inner rod 404, a first clamping plate 405, a second clamping plate 406, a mounting plate 501, and a turntable 502. The mounting plate 501 is fixedly connected to the top of the base 1, the turntable 502 is rotatably connected to the inner wall of the mounting plate 501, the hydraulic telescopic rod 401 is fixedly connected to the surface of the turntable 502, the outer rod 402 is fixedly connected to the output end of the hydraulic telescopic rod 401, the inner rod 404 is slidably connected to the inner wall of the outer rod 402, and an elastic member is arranged inside the inner rod 404. When the metal pipe is placed into the device, the hydraulic telescopic rod 401 starts and extends to drive the outer rod 402 to move. The movement of the outer rod 402 drives the inner rod 404 to move. The movement of the inner rod 404 drives the first clamping plate 405 to move. The movement of the first clamping plate 405 drives the second clamping plate 406 to move. When the first clamping plate 405 contacts the pipe fitting, the hydraulic telescopic rod 401 continues to extend. The inner rod 404 is blocked by the pipe fitting and the inner rod 404 will compress the elastic member inside the outer rod 402. At the same time, as the hydraulic telescopic rod 401 continues to extend, the outer rod 402 pushes the second clamping plate 406 to rotate towards the pipe fitting along the hinge joint of the first clamping plate 405 and clamp the pipe fitting. When the set pressure value is reached, the hydraulic telescopic rod 401 stops extending. By clamping with multiple clamping plates, the force-bearing area is increased. After the contact area increases, the clamping force is evenly distributed over a larger area to prevent the deformation of the pipe fitting. After the area increases, the friction force of the clamping plate on the pipe fitting can also be increased to prevent the pipe fitting from slipping during subsequent rotation. The first clamping plate 405 is fixedly connected to one end of the inner rod 404 away from the hydraulic telescopic rod 401. The second clamping plate 406 is hinged on the upper and lower sides of the first clamping plate 405. The guide rod 403 is hinged on the upper and lower side surfaces of the outer rod 402. The guide rod 403 is hinged on the left side of the second clamping plate 406. The number of mounting plates 501 is two, and the two mounting plates 501 are symmetrically distributed on the top of the base 1.

[0015] Working principle: When the metal pipe is placed into the device, the hydraulic telescopic rod 401 starts and extends to drive the outer rod 402 to move. The movement of the outer rod 402 drives the inner rod 404 to move. The movement of the inner rod 404 drives the first clamping plate 405 to move. The movement of the first clamping plate 405 drives the second clamping plate 406 to move. When the first clamping plate 405 contacts the pipe fitting, the hydraulic telescopic rod 401 continues to extend. The inner rod 404 is blocked by the pipe fitting and the inner rod 404 will compress the elastic member inside the outer rod 402. At the same time, as the hydraulic telescopic rod 401 continues to extend, the outer rod 402 pushes the second clamping plate 406 to rotate towards the pipe fitting along the hinge of the first clamping plate 405 and clamp the pipe fitting. When the set pressure value is reached, the hydraulic telescopic rod 401 stops extending. By clamping with multiple clamping plates, the stress-bearing area is increased. After the contact area increases, the clamping force is evenly distributed over a larger area to prevent the deformation of the pipe fitting. After the area increases, the friction force of the clamping plate on the pipe fitting can also be increased to prevent the pipe fitting from slipping during subsequent rotation.

[0016] Please refer to Figures 1-9 , on the basis of the above embodiments, in another embodiment of the present invention, the turning and cutting mechanism 5 includes: a motor 503 and a gear 504. The motor 503 is fixedly connected to the front surface of the mounting plate 501, and the gear 504 is fixedly connected to the output end of the motor 503. When the clamping mechanism 4 clamps the pipe fitting, the motor 503 starts to drive the gear 504 to rotate. The rotation of the gear 504 drives the turntable 502 engaged therewith to rotate. The rotation of the turntable 502 drives the pipe fitting to rotate through the clamping mechanism 4. The cutting saw 3 starts, and the high-speed rotating saw blade slowly moves to the surface of the pipe fitting to start cutting, and the rotation direction of the pipe fitting is opposite to the feeding direction of the saw blade, which can achieve the effect of reducing burrs. The turning and cutting mechanism 5 further includes: a guard plate 505, a hammer 506, and a push rod 507. The guard plate 505 is fixedly connected between the two mounting plates 501. The hammer 506 rotates on the surface of the mounting plate 501 through a torsion spring. The push rod 507 is fixedly connected to the surface of the mounting plate 501. The guard plate 505 is made of a transparent material. The hammer 506 contacts the guard plate 505. The gear 504 meshes with the teeth on the circumferential surface of the turntable 502. The saw blade quickly feeds to half the depth of the pipe wall at the beginning of cutting to complete the first-stage cutting, and the speed is reduced in the second stage to complete the remaining cutting, reducing stress concentration at the end section. With the rotation of the pipe fitting, the effect of preventing deformation can be achieved, and the uniformity and accuracy of the cut can also be improved; while the turntable 502 rotates, it drives the push rod 507 to rotate. The rotation of the push rod 507 will contact the hammer 506. Continuing to rotate, the push rod 507 will toggle the hammer 506 to compress the torsion spring. When the push rod 507 moves away from the hammer 506, the hammer 506 will knock on the guard plate 505 to shake off the metal chips splashed onto the surface, preventing the accumulation of metal chips from affecting the observation of the cutting process; The cleaning mechanism 6 includes: a slider 601, a spring 602, a transmission rod 607, a first slide rail 608, a baffle 609, and a discharge port 611. The first slide rail 608 is fixedly connected to the side of the mounting plate 501 away from the hydraulic telescopic rod 401. The slider 601 is slidably connected to the first slide rail 608. The spring 602 is fixedly connected to the left side of the slider 601. The baffle 609 is fixedly connected to the top of the slider 601. The transmission rod 607 is fixedly connected to the bottom of the slider 601. The discharge port 611 is opened on the surface of the base 1 and the number of the discharge ports 611 is two. During the cutting process, the rotation of the turntable 502 at one end of the device drives the push rod 507 to push the baffle 609 to move. As the turntable 502 rotates, the push rod 507 will push the baffle 609 to the middle of the stroke of the first slide rail 608. When the turntable 502 continues to rotate, the push rod 507 will move away from the baffle 609. At this time, the push rod 507 at the other end contacts and pushes the baffle 609 to complete the second half of the stroke. The movement of the baffle 609 drives the slider 601 to move. The movement of the slider 601 drives the transmission rod 607 to move. The movement of the transmission rod 607 drives the connecting plate 603 to move. The movement of the connecting plate 603 drives the scraping strip 604 and the friction wheel 606 to move at the same time. The movement of the scraping strip 604 scrapes the metal chips generated by cutting to the discharge port 611, preventing the accumulation of metal chips from affecting subsequent cutting operations, and can also collect and recycle the metal chips, reducing material waste and production costs. The cleaning mechanism 6 further includes: a connecting plate 603, a scraping strip 604, a cylindrical brush 605, a friction wheel 606, and a second slide rail 610. The second slide rail 610 is fixedly connected to the side of the mounting plate 501 away from the hydraulic telescopic rod 401. The connecting plate 603 is slidably connected to the outer wall of the second slide rail 610. The scraping strip 604 is fixedly connected to the bottom of the connecting plate 603. The friction wheel 606 is rotatably connected to the inner wall of the connecting plate 603. The cylindrical brush 605 is fixedly connected to the axis of the friction wheel 606. The friction wheel 606 contacts the top of the base 1. The friction wheel 606 contacts the surface of the base 1. The cylindrical brush 605 contacts the surface of the base 1. The transmission rod 607 is fixedly connected to the top of the connecting plate 603. The spring 602 is fixedly connected to the side of the mounting plate 501 away from the hydraulic telescopic rod 401. The baffle 609 is located on the movement track of the push rod 507. The number of the baffles 609 is two, and the left baffle 609 is located on the right side of the slider 601. The movement of the friction wheel 606 causes it to rotate due to contact and friction with the base 1. The rotation of the friction wheel 606 drives the cylindrical brush 605 to rotate. The rotation of the cylindrical brush 605 further grinds the metal chips adhered to the base 1 to make it convenient for the subsequent cleaning of the scraping strip 604, improving the cleaning effect, preventing the tightly adhered metal chips from damaging the scraping strip 604, reducing the replacement frequency, improving the durability of the device, and reducing the maintenance cost.

[0017] Working principle: When the clamping mechanism 4 clamps the pipe fitting, the motor 503 starts to drive the gear 504 to rotate. The rotation of the gear 504 drives the rotating disc 502 engaged with it to rotate. The rotation of the rotating disc 502 drives the pipe fitting to rotate through the clamping mechanism 4. The cutting saw 3 starts, and the saw blade rotating at high speed slowly moves to the surface of the pipe fitting to start cutting. The rotation direction of the pipe fitting is opposite to the feeding direction of the saw blade, which can reduce burrs. At the same time, when the cutting starts, the saw blade quickly feeds to half of the depth of the pipe wall to complete the first-stage cutting, and the speed is reduced in the second stage to complete the remaining cutting, reducing stress concentration at the end section. With the rotation of the pipe fitting, the effect of preventing deformation can be achieved, and the uniformity and accuracy of the cut can also be improved; while the rotating disc 502 rotates, it drives the push rod 507 to rotate. When the push rod 507 rotates, it will contact the knocking hammer 506 and continue to rotate. The push rod 507 will push the knocking hammer 506 to compress the torsion spring. When the push rod 507 moves away from the knocking hammer 506, the knocking hammer 506 will be driven by the restoring force of the torsion spring to knock the guard plate 505 to shake off the metal chips flying onto the surface, preventing the accumulation of metal chips from affecting the observation of the cutting process.

[0018] During the cutting process, the rotating disc 502 at one end of the device rotates to drive the push rod 507 to push the baffle 609 to move. As the rotating disc 502 rotates, the push rod 507 will push the baffle 609 to the middle of the stroke of the slide rail 608. When the rotating disc 502 continues to rotate, the push rod 507 will move away from the baffle 609. At this time, the push rod 507 at the other end contacts and pushes the baffle 609 to complete the second half of the stroke. The movement of the baffle 609 drives the slider 601 to move, the movement of the slider 601 drives the transmission rod 607 to move, the movement of the transmission rod 607 drives the connecting plate 603 to move, and the movement of the connecting plate 603 drives the scraping strip 604 and the friction wheel 606 to move at the same time. The movement of the scraping strip 604 scrapes the metal chips generated by cutting to the discharge port 611, preventing the accumulation of metal chips from affecting subsequent cutting operations, and can also collect and recycle the metal chips, reducing material waste and production costs. The movement of the friction wheel 606 causes it to rotate due to contact and friction with the base 1. The rotation of the friction wheel 606 drives the cylindrical brush 605 to rotate. The rotation of the cylindrical brush 605 further polishes the metal chips adhered to the base 1 to facilitate the subsequent cleaning by the scraping strip 604, improving the cleaning effect, preventing the tightly adhered metal chips from damaging the scraping strip 604, reducing the replacement frequency, improving the durability of the device, and reducing the maintenance cost.

The above description is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention. Each component not clearly defined in this embodiment can be implemented by existing technologies.
