Description

Technical Field

[0001] The invention relates to the field of composite processing, in particular to a steel pipe cutting and chamfering device. Background Art

[0002] During the mechanical processing of steel pipes, in order to improve product quality and operational safety, it is usually necessary to chamfer the cut edges of the steel pipes.

[0003] When the current combined processing machine tools cut and chamfer steel pipes, the cut steel pipes need to be calibrated before the next chamfering work can be carried out, which adds an additional adjustment process for the steel pipes. The connection between the two processes of pipe cutting and chamfering is difficult, and the processing speed cannot be further improved. In addition, the positioning of the tools on both sides is prone to errors due to personnel adjustment problems, resulting in inconsistent chamfer angles, affecting the final processing quality. At the same time, the debris generated by the inner chamfer is easy to remain in the steel pipe, which is easy to cause the steel pipe to wear when accumulated friction occurs.

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0034] The receiving unit 4 includes a receiving platform 41 provided on the pipe cutting unit 1 for carrying the cut steel pipe 6, a guide platform 42 provided on one side of the receiving platform 41 for guiding the movement direction of the falling steel pipe 6, and a guide assembly 43 provided on the guide platform 42 for cooperating with the guide platform 42 to guide the movement of the steel pipe 6, thereby facilitating the collection of the processed steel pipe 6.

[0035] The chamfering unit 5 includes a fixed plate 51 arranged on the guide platform 42, which plays a supporting and fixing role, a motor 2 52 arranged on the fixed plate 51, which is used to generate power, a movable component 53 arranged on the fixed plate 51, which is used to cooperate with the motor 2 52 to move back and forth, a chamfering component 54 arranged on the movable component 53, which is used to cooperate with the movable component 53 to move back and forth to chamfer the rotating steel pipe 6, and an adjustment component 55 arranged on the chamfering component 54, which is used to adjust the opening and closing angles of the chamfering component 54 to facilitate the processing of chamfers of different sizes.

[0036] The pipe cutting unit 1 includes a base 11 for supporting the cutting portion 12 provided on the base 11 and located on one side of the receiving platform 41, for cutting the steel pipe 6. The cut steel pipe 6 will fall onto the receiving platform 41. A feeding portion 13 provided on one side of the base 11 and cooperating with the cutting portion 12 is used to feed the steel pipe 6 to the cutting portion 12 for continuous operation. A clamping device is provided on the base 11 for clamping the steel pipe 6 when the cutting portion 12 cuts the steel pipe 6, so as to facilitate the cutting action of the cutting portion 12.

[0037] The machine base 11 is provided with a waste trough 111 for collecting debris, which is used to uniformly collect the debris generated by cutting and chamfering.

[0038] In summary, when the device is running, the feeding part 13 conveys the steel pipe 6 to the cutting part 12. When the steel pipe 6 moves to the specified length, the cutting part 12 starts to cut the steel pipe 6. At this time, the cut steel pipe 6 falls onto the receiving platform 41 by gravity. At this time, the push-pull component 31 drives the grabbing component 33 to move above the receiving platform 41. At this time, the telescopic component 32 drives the grabbing component 33 to approach the receiving platform 41, and grabs the steel pipe 6 on the receiving platform 41 through the grabbing component 33. At this time, the grabbing component 33 drives the steel pipe 6 to leave the receiving platform 41 through the telescopic component 32, and then cooperates with the receiving platform 41 to drive the steel pipe 6 to the specified position. At this time, the movable component 53 is driven to move by the motor 2 52, so that the chamfering component 54 is close to the receiving platform Near the inner and outer edges of the steel pipe 6, the opening and closing angle of the chamfering component 54 is adjusted by the adjustment component 55. At this time, the rotating component 34 is started, and the steel pipe 6 is driven to rotate by the grabbing component 33. The movable component 53 drives the chamfering component 54 to gradually approach the inner and outer sides of the steel pipe 6 to chamfer the inner and outer sides of the steel pipe 6. When the chamfering is completed, the rotating component 34 is stopped, and the steel pipe 6 stops rotating. At this time, the chamfering component 54 is driven to leave the steel pipe 6 by the movable component 53. At this time, the grabbing component 33 is controlled to open and the steel pipe 6 is released. Through the action of gravity, the steel pipe 6 falls onto the guide platform 42, and the steel pipe 6 is guided into the material guide component 43 by the guide platform 42, and the steel pipe 6 is transported in an orderly manner by the material guide component 43.

[0039] Example 2, reference Figures 1-6 This is the second embodiment of the present invention. It differs from the previous embodiment in that the debris generated when chamfering the inner and outer sides of the steel pipe 6 is removed. Compared to the first embodiment, the limiting surface 22 is further configured to be inclined to limit the overall position angle and motion trajectory of the gripping unit 3.

[0040] The fixing plate 51 cooperates with the limiting surface 22 to be set at the same inclination angle, so that the chamfering unit 5 as a whole maintains the same angle as the grabbing unit 3, which facilitates simultaneous processing of both ends of the steel pipe 6.

[0041] The limiting surface 22 is provided with a sliding groove 23 for cooperating with the push-pull assembly 31 to move the grabbing unit 3 as a whole back and forth on the limiting surface 22 in cooperation with the push-pull assembly 31;

[0042] The movement direction of the push-pull assembly 31 is parallel to the inclined surface of the limiting surface 22. The push-pull assembly 31 includes a cylinder 311 provided on the limiting surface 22 for generating power, a sliding block 312 provided on the driving end of the cylinder 311 for cooperating with the cylinder 311 to move back and forth on the limiting surface 22 through the sliding groove 23, playing a connecting role, and a sliding rod 313 provided on the sliding groove 23 and slidingly cooperating with the sliding block 312 for supporting the back and forth movement of the sliding block 312. The limiting surface 22 cooperates with the push-pull assembly 31 to make the grabbing unit 3 as a whole tilted, so that the grabbed steel pipe 6 cooperates with the push-pull assembly 31 to be in an inclined state with different heights at both ends;

[0043] The movement direction of the telescopic component 32 is perpendicular to the movement direction of the push-pull component 31. The telescopic component 32 includes a cylinder 2 321 arranged on the sliding block 312, which is used to generate power, a connecting plate 322 arranged at the driving end of the cylinder 2 321, which is used to cooperate with the cylinder 2 321 to perform telescopic activities and play a supporting and connecting role, and a sliding rod 2 323 arranged on the connecting plate 322 and slidably connected to the sliding block 312, which is used to stabilize the telescopic activities of the connecting plate 322.

[0044] Among them, the grabbing assembly 33 includes a supporting shaft 331 provided on the telescopic assembly 32, which plays a supporting role; a movable shaft 332 provided on the telescopic assembly 32, which is used to move up and down on the connecting plate 322; a cylinder 333 provided on the telescopic assembly 32 for driving the movable shaft 332, which is used to drive the movable shaft 332 to move; a transmission belt 334 provided on the supporting shaft 331 and the movable shaft 332, which is used to cooperate with the movement of the movable shaft 332 to come into contact with the surface of the steel pipe 6; a connecting shaft 335 provided on the transmission belt 334; and a connecting rod 336 which is rotatably connected to the movable shaft 332 and the connecting shaft 335 at both ends. The connecting shaft 335 cooperates with the up and down movement of the movable shaft 332 through the connecting rod 336 to drive the transmission belt 334 to open or close, thereby clamping or releasing the steel pipe 6;

[0045] The telescopic assembly 32 is provided with a sliding cavity 3221 that cooperates with the driving track of the third cylinder 333, and is used to cooperate with the third cylinder 333 to drive the movable shaft 332 to move back and forth in the sliding cavity 3221;

[0046] The rotating assembly 34 includes a motor 1 341 provided on the telescopic assembly 32 for generating power, a power shaft 342 provided on the telescopic assembly 32 and fixedly connected to the driving end of the motor 1 341 for rotating in conjunction with the motor 1 341, and a driving wheel 343 provided on the power shaft 342 for rotating in conjunction with the power shaft 342.

[0047] The driven wheel 3311 arranged on the supporting shaft 331 meshes with the driving wheel 343, and the rotation of the driving wheel 343 drives the supporting shaft 331 to rotate. The supporting shaft 331 and the transmission belt 334 are engaged with each other through the teeth and the grooves, ensuring that the supporting shaft 331 accurately drives the transmission belt 334, and at the same time prevents the transmission belt 334 from shifting. The transmission belt 334 in the groove can also increase the friction of the steel pipe 6 and enhance the gripping effect.

[0048] Among them, a material receiving trough 411 is provided on the material receiving platform 41, and the material receiving trough 411 is set to an inclined state corresponding to the limiting surface 22, so that the steel pipe 6 falls into the material receiving trough 411 in an inclined state, which is the same as the inclination angle of the limiting surface 22, so that the grasping component 33 can better grasp the steel pipe 6, and can directly perform chamfering processing, avoid position adjustment of the steel pipe, reduce processing procedures, and improve processing efficiency.

[0049] The guide platform 42 is provided with a guide surface 421, which is arranged in an inclined state. The side of the guide surface 421 close to the receiving trough 411 is higher than the side of the guide surface 421 away from the receiving trough 411. Through this arrangement, the falling steel pipe 6 is guided to the side away from the receiving trough 411.

[0050] The side of the guide surface 421 away from the material guide assembly 43 is higher than the side of the guide surface 421 close to the material guide assembly 43. Through this arrangement, the steel pipe 6 is guided to slide on the material guide assembly 43, which facilitates the orderly transportation of the steel pipe 6 through the material guide assembly 43.

[0051] The material guide assembly 43 includes a horizontal axis 431 arranged on the guide platform 42, which is used to transport the chamfered steel pipe 6, and a vertical axis 432 arranged on the horizontal axis 431, which is used to catch the steel pipe 6 that slides down and cooperate with the horizontal axis 431 to transport the steel pipe 6. Multiple groups of material guide assemblies 43 are arranged in conjunction with the guide platform 42.

[0052] The rest of the structure is the same as that of Example 1.

[0053] In summary, when the cutting part 12 cuts the steel pipe 6, the steel pipe 6 falls into the receiving groove 411. The steel pipe 6 presents the same inclination angle as the limiting surface 22 through the receiving groove 411. At this time, the cylinder 1 311 moves toward the direction close to the receiving groove 411 through the sliding block 312. At this time, the cylinder 2 321 controls the connecting plate 322 to approach the steel pipe 6 on the receiving groove 411. At this time, the cylinder 3 333 controls the movable shaft 332 to move downward. At this time, under the action of the connecting rod 336, The connecting shaft 335 drives the transmission belt 334 to open. When the transmission belt 334 covers the steel pipe 6, the cylinder 333 controls the movable shaft 332 to move up. At this time, under the action of the connecting rod 336, the connecting shaft 335 drives the transmission belt 334 to close. At this time, the transmission belt 334 firmly grasps the steel pipe 6. At this time, the steel pipe 6 cooperates with the material receiving trough 411 to present an inclined state with different heights at both ends. This state coincides with the angle of the chamfering processing state. At this time, through the connecting plate 322 and the sliding block The action of 312 drives the transmission belt 334 to grasp the steel pipe 6 and move it to the specified position. At this time, the opening and closing angle of the chamfering assembly 54 is adjusted by the adjusting assembly 55. At this time, the chamfering assembly 54 is driven to approach the inner and outer sides of the steel pipe 6 through the movable assembly 53. At this time, the motor 1 341 is started, and the supporting shaft 331 is driven to rotate by the driving wheel 343 and the driven wheel 3311. The rotation of the supporting shaft 331 drives the transmission belt 334 to transmit, thereby driving the steel pipe 6 clamped by the transmission belt 334 to rotate, and the inner and outer sides of the steel pipe 6 are chamfered by the chamfering assembly 54 approaching. At this time, since the steel pipe 6 is in an inclined state, the chamfering assembly 54 generates debris when processing the steel pipe 6. The debris generated by processing the outer side directly falls into the waste trough 111, and the debris generated by processing the inner side and entering the inside of the steel pipe 6 is discharged from the steel pipe 6 through the inclination and rotation of the steel pipe 6 and enters the waste trough 111.

[0054] When the chamfering of the steel pipe 6 is completed, the motor 341 stops, and the transmission belt 334 drives the steel pipe 6 to stop rotating. The cylinder 333 drives the movable shaft 332 to move downward, driving the transmission belt 334 to open, so that the steel pipe 6 falls onto the guide surface 421, and the steel pipe 6 is guided into the horizontal axis 431 through the guide surface 421. At this time, the longitudinal axis 432 supports the steel pipe 6 and cooperates with the horizontal axis 431 to transport the steel pipe 6.

[0055] Example 3, reference Figures 1-9, which is the second embodiment of the present invention, differs from the previous embodiment in that: the chamfering knife 1 5421 and the chamfering knife 2 5431 are adjusted synchronously. Compared with embodiment 2, the movable assembly 53 further includes a bidirectional screw 531 provided on the fixed plate 51 and connected to the driving end of the motor 2 52, which is used to cooperate with the motor 2 52 for rotation, a sliding rod 3 532 provided on the fixed plate 51, which plays a role in supporting and stabilizing movement, and a moving block 533 slidably provided on the fixed plate 51 and engaged with the bidirectional screw 531 through a thread, which is used to drive the chamfering assembly 54 to move back and forth;

[0056] A group of moving blocks 533 are provided at each end of the bidirectional screw rod 531, which are used to cooperate with the chamfering component 54 to simultaneously process the two ends of the steel pipe 6. The moving block 533 is provided with a threaded sleeve threadedly connected to the bidirectional screw rod 531. By adjusting the rotation of the threaded sleeve, the distance from the two groups of moving blocks 533 to the two ends of the steel pipe 6 can be adjusted, thereby further improving the applicability of the device.

[0057] The chamfering assembly 54 includes a support column 541 provided on the movable block 533 for supporting the outer side of the steel pipe 6, a rotating block 542 provided on the support column 541 for chamfering the outer side of the steel pipe 6, and a rotating block 543 provided on the rotating block 542 for chamfering the inner side of the steel pipe 6.

[0059] The adjustment assembly 55 includes a fixed base 551 disposed on the support column 541, which serves as a fixed connection and support, a worm 552 disposed on the fixed base 551, which is used to rotate an output wheel 1 553 disposed on the support column 541, and an output wheel 2 554 disposed on the output wheel 1 553. Both the output wheel 1 553 and the output wheel 2 554 are used for transmission to transmit power.

[0060] The first rotating block 542 is provided with a ring gear 5422 that cooperates with the worm 552 and is used to rotate with the worm 552, thereby driving the first rotating block 542 to rotate. The first rotating block 542 is provided with a connecting groove 5423 for accommodating the first output wheel 553 and the second output wheel 554. The inner wall of the connecting groove 5423 is provided with a second ring gear 5424 that meshes with the second output wheel 554. When the first rotating block 542 rotates, the second output wheel 554 is driven to rotate through the connecting groove 5423.

[0061] The second rotating block 543 is provided with a second connecting groove 5432 for rotating with the first rotating block 542. The second connecting groove 5432 is provided with a third gear ring 5433 that meshes with the first output wheel 553. The second output wheel 554 rotates to drive the first output wheel 553 to rotate. The first output wheel 553 drives the second rotating block 543 to rotate via the third gear ring 5433.

[0062] The gear ratio of the ring gear 2 5424 to the output wheel 2 554 is equal to the gear ratio of the ring gear 3 5433 to the output wheel 1 553. Through such a setting, the synchronous adjustment of the rotation angle of the rotating block 1 542 and the rotating block 2 543 is achieved. Since the directions of the ring gear 3 5433 and the ring gear 2 5424 are relative, when the output wheel 2 554 and the output wheel 1 553 rotate, the rotation angles of the rotating block 1 542 and the rotating block 2 543 are the same in size but opposite in direction, thereby achieving the synchronous opening and closing of the rotating block 1 542 and the rotating block 2 543, so that the chamfering angles of the chamfering knife 1 5421 and the chamfering knife 2 5431 on the inside and outside of the steel pipe 6 remain consistent.

[0063] The rest of the structure is the same as that of Example 2.

[0064] In summary, when the transmission belt 334 grasps the steel pipe 6 and moves to the specified position, the worm 552 is rotated at this time, and the rotating block 1 542 is driven to rotate through the ring gear 1 5422. At this time, the ring gear 2 5424 drives the output wheel 1 553 to rotate through the output wheel 2 554. At this time, the output wheel 1 553 drives the rotating block 2 543 to rotate through the ring gear 3 5433. Since the tooth ratio of the ring gear 2 5424 and the output wheel 2 554 is equal to the tooth ratio of the ring gear 3 5433 and the output wheel 1 553, And the directions of gear ring three 5433 and gear ring two 5424 are opposite, so the rotation angles of chamfering knife one 5421 and chamfering knife two 5431 are the same in size but opposite in direction. At this time, the opening and closing angles of chamfering knife one 5421 and chamfering knife two 5431 are adjusted to appropriate angles. At this time, start motor two 52 to drive the bidirectional screw rod 531 to rotate, and drive the chamfering assembly 54 as a whole to approach the two ends of the steel pipe 6 through the moving block 533, and cooperate with the rotating steel pipe 6 to chamfer the inner and outer sides of the steel pipe 6.
