Description

Technical Field

[0001] This invention relates to the field of metal pipe processing equipment technology, specifically a high-efficiency pipe cutting machine. Background Technology

[0002] Metal pipes are basic connectors in industry and daily life. Their applications are wide and diverse, mainly due to their material advantages such as high strength, corrosion resistance, thermal conductivity, electrical conductivity, and plasticity. They can adapt to the functional needs of different scenarios and cover multiple fields such as civil, industrial, construction, and transportation.

[0003] When processing metal pipes, pipe cutting machines are indispensable. Pipe cutting machines are automated or semi-automated equipment specifically designed for cutting various types of pipes, such as metal pipes, plastic pipes, and composite material pipes. Their core value lies in accurately, efficiently, and stably cutting pipes into specified lengths or shapes.

[0004] The prior art, such as the one disclosed in CN112605461B, discloses a high-efficiency pipe cutting machine, including a worktable and a drive assembly. The drive assembly is connected to the bottom of the worktable, and a mounting plate is hinged to the top surface of the worktable, located above the worktable. A blade for cutting pipes is rotatably connected to the bottom surface of the mounting plate. The drive assembly is connected to the blade via a drive shaft. A control assembly is provided at the bottom of the worktable and connected to the mounting plate. Two opposing support rollers are rotatably connected to the top surface of the worktable, located below the blade, with a gap between the two support rollers adapted to the pipe diameter. The length direction of the support rollers is parallel to the length direction of the pipe. A support block is connected to the worktable via a first extension plate, away from the support rollers. The blade is located between the support block and the support rollers and close to the support rollers. A positioning assembly is connected to the top surface of the worktable, with the positioning assembly close to the end of the support rollers away from the support block. This application has the effect of improving the efficiency of pipe cutting.

[0005] Although the aforementioned pipe cutting machine can cut metal pipes, it still requires manual pressing to cut the pipes. Furthermore, the internal positioning and traction mechanisms of the machine do not coordinate well each time a pipe is cut, resulting in a longer bottleneck time per unit of cutting time and reducing the efficiency of the machine. The need for manual intervention also increases the cost of pipe processing. Therefore, a more efficient pipe cutting machine is needed to solve the problems mentioned above. Summary of the Invention

The outer end face of the first pin is rotatably engaged with a T-shaped swing plate, and a second guide shaft is provided on the side end face of the T-shaped swing plate. A first guide shaft is provided at the bottom of the side end face of the T-shaped swing plate. Swing push rods are fixedly engaged at the top of the two sets of T-shaped swing plates. Two sets of second linear slide rails are symmetrically provided on the inner end face of the frame, and two sets of pipe cutting devices are symmetrically engaged on the inner end face of the frame through the second linear slide rails.

[0016] Preferably, the pipe cutting device includes a pressing slide, with a third guide pin symmetrically arranged near the front of the side end face of the pressing slide, and two sets of second linear sliders symmetrically arranged near the middle of the side end face of the pressing slide. A pipe clamping plate is slidably engaged at the rear of the inner end face of the pressing slide, and a cutting tool is arranged at the middle of the upper end face of the pressing slide. The pressing slide and the pipe clamping plate are fixedly connected by a return spring. When the upper and lower sets of pipe clamping plates clamp and limit metal pipes of different diameters through the clamping openings, the pipe clamping plates protrude from the bottom of the cutting tool, allowing the upper and lower sets of pipe clamping plates to contact and limit the metal pipes in advance. At the same time, the elastic space between the return spring and the pipe clamping plate provides sufficient guiding space for the subsequent pipe clamping plates to limit metal pipes of different models.

[0017] Preferably, the first bevel gear and the second bevel gear are meshed together, the lower end face of the driving gear is meshed with the driven gear, the transmission chuck is adapted to the swing shaft and the swing shaft slide through the swing shaft to drive the support plate to move back and forth on the upper part of the positioning base, and the alignment chuck is fixedly engaged with the rhomboid bearing seat. During transmission, the meshing of the driving gear and the driven gear can improve the torque and stability of the power output. At the same time, the 1:1 transmission ratio of the first bevel gear and the second bevel gear can improve the synchronicity of the processing device cutting and pulling the metal tube when the cyclic transmission device drives the processing device to move back and forth.

[0018] Preferably, the driven synchronous pulley is meshed with the driving synchronous pulley via the synchronous belt, and the third bevel gear is meshed with the fourth bevel gear. Both the fourth bevel gear and the support shaft seat have sliding grooves at their internal centers, and both the fourth bevel gear and the support shaft seat are slidably engaged with the transmission shaft via these sliding grooves. The two sets of support shaft seats inside the support shaft seat can provide sufficient support for the transmission shaft via the sliding grooves, improving the stability of the transmission. Simultaneously, the transmission shaft can provide power to the fourth bevel gear simultaneously as the processing device reciprocates via the sliding grooves, thereby providing power to the guiding device and the processing device, further improving the stability of the transmission.

The L-shaped bracket is adapted to the cam groove via the cam slide shaft and is reciprocally slidably disposed on the upper part of the top plate. The upper third guide bracket is slidably engaged with the second guide bracket. The T-shaped swing plate is adapted to the first slide shaft groove via the first guide bracket and is thus actuated to rotate the L-shaped swing plate around the second pin shaft. The lower third guide bracket is slidably engaged with the second slide shaft groove. Both the upper and lower sets of pressing slide blocks are slidably engaged with the outside of the second linear slide rail via the second linear slider. The upper and lower sets of pipe clamping plates are plug-in type. The upper pipe clamping plate and the lower... The pipe clamping plates are slidably inserted in the middle, and the clamping openings of the upper and lower sets of pipe clamping plates are V-shaped. When the two sets of pipe clamping plates and the cutting tool are centrifugally pressed together and centrifugally discharged, the first and second pins can provide lever support fulcrums for the T-shaped swing plate and the L-shaped swing plate, respectively. When the T-shaped swing plate rotates inward, the bottom of the T-shaped swing plate can move the L-shaped swing plate inward around the second pin fulcrum through the cooperation of the first guide pin and the first sliding shaft groove. Simultaneously, the T-shaped swing plate can drive the second guide pin to rotate downward, so that the second sliding shaft groove and the second guide pin can simultaneously drive the upper and lower sets of third guide pins to move inward, which facilitates the upper and lower sets of pipe clamping plates and the cutting tool to limit and cut the metal pipe, improving the stability and accuracy of pipe cutting.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. This invention is a high-speed pipe cutting device for metal pipes. When cutting metal pipes, the servo motor can drive the control device to rotate in a circular motion through the steering reducer. This allows the control device to drive the processing device to move back and forth through the swing shaft slide. At the same time, the steering reducer can provide power to the processing device through the first bevel gear and the transmission shaft. This allows the processing device to cooperate with the cyclic guidance of the cyclic transmission device to perform equidistant pulling and cutting operations on the metal pipe simultaneously, effectively improving the efficiency of the equipment in automatically cutting metal pipes at equal intervals.

[0022] 2. This invention, by setting up a driven gear, a driving gear, a first bevel gear, a second bevel gear, a guiding device, and a driving device, enables the steering reducer to synchronously drive two sets of control devices to rotate in a circular motion during pipe cutting transmission via the driving and driven gears. This allows the control devices to drive the processing device to move back and forth via the swing shaft slide. Simultaneously, the first bevel gear drives the transmission clamp shaft to rotate via the second bevel gear. This allows the transmission clamp shaft to provide power for pipe cutting to the processing device through synchronous transmission via the guiding device and the driving device. Consequently, the processing device can simultaneously clamp, pull, and cut the metal pipe during back and forth movement, effectively reducing the bottleneck time when processing metal pipes and thus improving the efficiency of pipe cutting. It also improves the efficiency of power utilization.

[0023] 3. By setting up a processing device, when cutting metal tubes, the swing arm slide can drive two sets of T-shaped swing plates to move back and forth through the swing push rod. This allows the two sets of T-shaped swing plates to drive two sets of second sliding shaft grooves and second guide pins to move centripetally and centrifugally through the lever principle. This, in turn, can drive two sets of third guide pins and the cutting tool to move centripetally and centrifugally. The rigidly limited mechanical tube cutting structure can effectively improve the accuracy and stability of the cutting tool in cutting metal tubes.

[0024] 4. By setting up a control device and pipe clamping plates, this invention allows the stepper motor to be connected to the ball screw and ball slide via a threaded connection when processing metal pipes of different models. This adjusts the spacing of the swing shaft driving the swing shaft slide to reciprocate and feed the pipes, thereby quickly and accurately adjusting the length of the metal pipes fed at equal intervals each time. This facilitates the processing of metal pipes of different lengths at the subsequent pipe cutting point, effectively improving the adaptability of the equipment. At the same time, the V-shaped clamping openings inside the upper and lower sets of pipe clamping plates facilitate the subsequent adaptation to the limiting of metal pipes of different diameters, effectively improving the adaptability and practicality of the equipment in processing metal pipes of different models.

When the upper and lower sets of pipe clamping plates 521 clamp and limit the metal pipes 1 of different diameters through the clamping opening, the pipe clamping plate 521 protrudes from the bottom of the cutting tool 522, so that the upper and lower sets of pipe clamping plates 521 can contact and limit the metal pipes 1 in advance. At the same time, the elastic space between the return spring 526 and the pipe clamping plate 521 can provide sufficient guiding space for the pipe clamping plate 521 to limit the metal pipes 1 of different models in the future.

[0069] like Figure 8The first bevel gear 215 meshes with the second bevel gear 216, and the lower end face of the driving gear 218 meshes with the driven gear 217. During transmission, the meshing of the driving gear 218 and the driven gear 217 can improve the torque and stability of the power output. At the same time, the 1:1 transmission ratio between the first bevel gear 215 and the second bevel gear 216 can improve the synchronicity of the cutting and pulling of the metal tube 1 by the processing device 5 when the cyclic transmission device 2 drives the processing device 5 to move back and forth.

[0070] like Figure 7 and Figure 10 The transmission chuck 221 is adapted to the swing shaft slide 210 through the swing shaft 223, thereby driving the support plate 24 to move back and forth on the upper part of the positioning base 26, and the positioning chuck 226 is fixedly engaged with the rhomboid bearing seat 29.

[0071] like Figure 12 The driven synchronous pulley 31 is meshed with the driving synchronous pulley 41 through the synchronous belt 9. The third bevel gear 42 is meshed with the fourth bevel gear 43. During transmission, the transmission ratio of the third bevel gear 42 to the fourth bevel gear 43 is 1:1. At the same time, the radius and number of teeth of the driving synchronous pulley 41 and the driven synchronous pulley 31 are equal, which can improve the stability and accuracy of subsequent transmission.

[0072] like Figure 9 and Figure 12 Both the fourth bevel gear 43 and the support shaft seat 46 have sliding shaft grooves 44 at their internal centers. The fourth bevel gear 43 and the support shaft seat 46 are slidably engaged with the transmission shaft 21 through the sliding shaft grooves 44. The two sets of support shaft seats 46 inside the support shaft seat 45 can provide sufficient support for the transmission shaft 21 through the sliding shaft grooves 44, thereby improving the stability of the transmission of the transmission shaft 21. At the same time, the transmission shaft 21 can provide power to the fourth bevel gear 43 simultaneously when the processing device 5 reciprocates through the sliding shaft grooves 44, and then provide power to the guide device 3 and the processing device 5.

[0073] like Figure 13 The swing push rod 54 is slidably engaged with the swing rod slide 55. The L-shaped bracket 56 is adapted to the cam groove 36 through the cam slide shaft 516 and is reciprocally slidably mounted on the upper part of the top plate 58. The hollow groove inside the swing rod slide 55 can provide sufficient vertical displacement space for the swing push rod 54 to guide it, so that the swing push rod 54 can drive the swing rod slide 55 to move back and forth on the upper part of the top plate 58, thereby providing power for the T-shaped swing plate 57.

[0074] like Figure 13 and Figure 14The upper third guide shaft 524 is slidably engaged with the second guide shaft 515, and the T-shaped swing plate 57 is adapted to the first sliding shaft groove 510 through the first guide shaft 514, thereby actuating the L-shaped swing plate 512 to rotate around the second pin 511. The lower third guide shaft 524 is slidably engaged with the second sliding shaft groove 513. When the two sets of pipe clamping plates 521 and cutting blades 522 are centrifugally pressed together and centrifugally discharged, the first pin 59 and the second pin 511 can provide lever support fulcrums for the T-shaped swing plate 57 and the L-shaped swing plate 512, respectively. When the T-shaped swing plate 57 rotates inward, the bottom of the T-shaped swing plate 57 can move the L-shaped swing plate 512 to rotate inward with the second pin 511 as the fulcrum through the cooperation of the first guide pin 514 and the first sliding groove 510. Simultaneously, the T-shaped swing plate 57 can drive the second guide pin 515 to rotate downward, so that the second sliding groove 513 and the second guide pin 515 can simultaneously drive the upper and lower sets of third guide pins 524 to move centripetally. This facilitates the upper and lower sets of pipe clamping plates 521 and cutting tools 522 to limit and cut the metal pipe 1, improving the stability and accuracy of pipe cutting.

[0075] like Figure 13 Both the upper and lower sets of pressing slide blocks 523 are slidably engaged with the outside of the second linear slide rail 53 through the second linear slider 525, which can effectively improve the stability of the upper two sets of cutting tools 522 and pipe clamping plate 521 in vertical displacement.

[0076] like Figure 14 The upper and lower sets of pipe clamping plates 521 are plug-in type. The upper pipe clamping plate 521 can be adapted to plug into the lower pipe clamping plate 521. At the same time, the upper pipe clamping plate 521 is plugged into the lower pipe clamping plate 521, which can also provide sufficient guiding space for subsequent clamping and support of metal pipes 1 of different diameters.

[0077] like Figure 15 The upper pipe clamping plate 521 and the lower pipe clamping plate 521 are slidably inserted into each other at the middle. The clamping openings of the upper and lower pipe clamping plates 521 are V-shaped. Preferably, the clamping openings of the upper and lower pipe clamping plates 521 are fitted with adhesive patches. The adhesive patches can increase the friction with the outer shell of the metal pipe 1, thereby improving the stability of the clamping and limiting of the metal pipe 1 by the upper and lower pipe clamping plates 521. At the same time, the clamping openings of the pipe clamping plates 521 are V-shaped, which can facilitate the clamping and limiting of metal pipes 1 of different diameters by the upper and lower pipe clamping plates 521.

[0078] Working principle: Before processing the metal tube 1, the operator can position the feeding module of the metal tube 1 at the rear of the support base plate 6, so as to facilitate the subsequent feeding of the metal tube 1 to be processed into the processing device 5, thereby improving the efficiency of subsequent processing.

[0079] like Figure 7 and Figure 8 As shown, when processing the metal tube 1, the operator can start the servo motor 211 through the external control panel. At this time, the servo motor 211 can drive the bottom steering reducer 212 to rotate. At the same time, the steering reducer 212 can drive the drive gear 218 to rotate through two sets of couplings 219. At this time, the drive gear 218 can drive the bottom driven gear 217 to rotate. Since the radius of the drive gear 218 is much smaller than that of the driven gear 217, it can perform torque increase operation when driving the driven gear 217 to rotate, thereby improving the stability of the driven gear 217 transmission.

[0080] like Figure 8 and Figure 10 When the driven gear 217 rotates, the driven gear 217 can synchronously drive the transmission chuck 221 and the first bevel gear 215 to rotate through the alignment chuck shaft 226;

[0081] When the second bevel gear 216 rotates, it synchronously drives the transmission shaft 21 to rotate. Figure 9 and Figure 12 When the transmission shaft 21 rotates, it can synchronously drive the fourth bevel gear 43 to rotate through the sliding shaft groove 44. The fourth bevel gear 43 can then mesh with the third bevel gear 42, thereby driving the drive synchronous pulley 41 to rotate synchronously. Figure 11 The driving synchronous pulley 41 can synchronously drive the driven synchronous pulley 31 to rotate via the synchronous belt 9. The driven synchronous pulley 31 can synchronously drive the cam 35 to rotate in a circular motion via the transmission shaft 32. Figure 11 and Figure 6 When the cam 35 rotates in a circular motion, it can synchronously drive the cam groove 36 to rotate in a circular motion. At this time, the cam groove 36 can be limited by sliding with the two sets of cam sliding shafts 516, thereby driving the rocker arm slide 55 to move back and forth on the top plate 58. Figure 14When the aforementioned rocker arm slide 55 moves forward, the rocker arm slide 55 can drive the swing push rod 54 to move forward synchronously. At the same time, the swing push rod 54 can drive the two sets of T-shaped swing plates 57 to rotate around the first pin 59 as the axis, causing the second guide pin 515 and the first guide pin 514 to rotate downward around the first pin 59. At the same time, when the first guide pin 514 rotates downward, it can slide and adapt to the first sliding shaft groove 510, thereby driving the L-shaped swing plate 512 to rotate around the second pin 511 as the axis. At this time, the second sliding shaft groove 513 at the front of the L-shaped swing plate 512 tilts upward. The second guide pin 515 at the top can drive the pressing slide 52 through the third guide pin 524 at the top. 3. The cutting tool 522 and the pipe clamping plate 521 move down synchronously. The second sliding groove 513 located at the bottom can drive the pressing slide 523, the cutting tool 522 and the pipe clamping plate 521 to move up through the third guide pin 524. When the upper and lower sets of pipe clamping plates 521 move towards the metal pipe 1, they can first limit the movement to the outside of the metal pipe 1, and then perform a full-range locking operation on the outside of the metal pipe 1. When the upper and lower sets of pressing slides 523 continue to move towards the center, the return spring 526 at the bottom of the pipe clamping plate 521 can provide sufficient limiting space for the pipe clamping plate 521 to continue locking the metal pipe 1. Then the upper and lower sets of pressing slides 523 can perform equidistant cutting operation on the metal pipe 1 locked by the pipe clamping plate 521 through the cutting tool 522.

[0082] like Figure 1 , Figure 8 and Figure 10 The aforementioned second bevel gear 216 can rotate synchronously with the driven gear 217. When the driven gear 217 rotates, it can synchronously drive the two sets of transmission chucks 221 and swing shaft 223 to rotate in a circle through the alignment chuck shaft 226. At this time, the swing shaft 223 can be limited by sliding with the swing shaft slide 210, thereby cyclically driving the swing shaft slide 210 and the support chuck plate 24 to move back and forth on the upper part of the positioning base 26, thus providing sufficient guiding space for the subsequent equidistant elongation and recutting of the uncut metal tube 1.

[0083] like Figure 6 , Figure 10 , Figure 11 and Figure 15During the aforementioned processing of the metal pipe 1, the two sets of matching pipe clamping plates 521 at the beginning can first lock and limit the unprocessed metal pipe 1. Then, the two sets of cutting tools 522 can cut off the protruding excess part of the metal pipe 1. At this time, it is in the initial state, the swing shaft 223 is located at the rear, and the two sets of cam sliding shafts 516 are just entering the large circle part of the cam groove 36. When the swing shaft 223 drives the swing shaft slide 210 and the support plate 24 to push the processing device 5 from back to front, the cam sliding shaft 516 enters the large circle track of the cam groove 36. That is, at this time, the two sets of pipe clamping plates 521 can clamp the cut metal pipe. The rear of 1 is locked, thereby pulling the metal tube 1 forward synchronously with the processing device 5. When the swing shaft 223 drives the processing device 5 to the front limit, the cam slide shaft 516 begins to enter the transition track of the small circle from the large circle of the cam groove 36, so that the pipe clamping plate 521 and the cutting tool 522 can move upward and get away from the limited metal tube 1. After the separation is completed, the swing shaft 223 can pull the processing device 5 backward. Then the cam slide shaft 516 enters the small circle track of the cam groove 36, keeping the pipe clamping plate 521 and the cutting tool 522 from contacting the metal tube 1 until it returns to the initial position and cuts and clamps the metal tube 1 again, repeating the cycle.

[0084] like Figure 16 The upper and lower sets of pipe clamping plates 521 are staggered and adaptable. The upper pipe clamping plate 521 can be inserted into the middle pipe clamping plate 521, and the clamping openings of both sets of pipe clamping plates 521 are V-shaped, allowing the upper and lower sets of pipe clamping plates 521 to accommodate the limiting of metal pipes 1 with different radii. Figure 10 If it is necessary to adjust the equidistant cutting length of the metal tube 1, the stepper motor 225 can be started. The stepper motor 225 can adjust the distance between the ball slide 222 and the center of the distance transmission chuck 221 through the ball screw 224, thereby adjusting the distance of the back-and-forth movement of the swing shaft slide 210, thus adjusting the equidistant length of the metal tube 1.

[0085] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
