[0021] A method for using a steel billet cutting device for steel pipe manufacturing comprises the following steps:

[0022] S1. When in use, start the steel billet conveying bracket to convey the steel pipe billet to the positioning annular bracket and the positioning bracket. When the steel pipe billet moves to the position of the positioning bracket, start the electric push rod with the arc clamping block to clamp the steel pipe billet, then start the cutting motor to rotate the saw disc, and start the transmission motor to rotate the gear rod at the same time, so that the gear rod is meshed with the gear ring on the annular bracket for transmission;

[0023] S2. As the gear rod rotates, the L-shaped bracket slides along the annular guide groove track of the side wall of the annular bracket, and the gear rod that rotates and moves along the circumference of the annular guide groove moves synchronously with the adjustment sleeve. During this process, the guide rod on the adjustment sleeve slides along the track of the spiral guide groove, so that the adjustment sleeve moves along the circumference of the annular bracket while gradually moving toward the center of the annular bracket, and the rotating saw disc cuts the steel pipe blank during the synchronous movement of the adjustment sleeve;

[0024] S3. After the steel pipe billet is cut off, the transmission motor is turned off. At this time, the electric telescopic rod is started to move the positioning bracket to the right, so that the steel pipe billet clamped on the positioning bracket moves to the right. At the same time, the electric telescopic rod pulls the annular bracket to translate to the right through the retaining ring. Since the adjustment sleeve moves to the extreme position toward the center of the annular bracket at this time, the arc block at the end of the adjustment sleeve that translates to the right contacts the inner circle of the conical ring adjustment bracket on the top of the base, so that the arc block is compressed and moves toward the inside of the adjustment sleeve with the U-shaped connecting rod. At this time, the U-shaped extrusion plate on the U-shaped connecting rod presses against the corresponding side wall position of the grinding plate, so that the grinding plate translates on the rotating rod and fits with the side wall of the saw disk. The rotating saw disk drives the grinding plate to rotate synchronously, so that the grinding plates on both sides of the saw disk respectively grind the ends of the steel pipe billet between the steel billet conveying bracket and the positioning bracket;

[0025] S4. After the steel pipe blank is polished, the electric telescopic rod is reset. At this time, the reset spring brings the U-shaped connecting rod to reset and move, and the transmission motor brings the gear rod to reverse, so that the adjustment sleeve is reset and moved to prepare for the next steel pipe blank cutting.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] In the present invention, through the coordinated use of components such as the billet conveying bracket, the annular bracket and the cutting mechanism, when the steel pipe billet on the billet conveying bracket passes through the annular bracket and is restricted to the side wall position of the positioning bracket, under the action of the cutting mechanism, the saw disk is rotated along the annular bracket and slowly moves toward the center position of the steel pipe billet for cutting processing, thereby reducing the contact area between the saw disk and the steel pipe billet during the cutting process, avoiding high temperature on the surface of the saw disk, reducing saw disk wear, increasing the service life of the saw disk, and improving the cutting quality.

[0028] In the present invention, through the coordinated use of components such as the positioning bracket, the cutting mechanism and the adjusting mechanism, after the steel pipe billet is cut off, the grinding plate inside the adjusting sleeve rotates with the saw disk under the cooperation of the adjusting mechanism and the cutting mechanism. At this time, during the rotation of the saw disk, the ends of the steel pipe billet on the steel billet conveying bracket and the positioning bracket are ground by two grinding plates to clean burrs, thereby further improving the regularity of the end face of the steel pipe billet after cutting and improving the quality of the later processing of the steel pipe.

[0029] In the present invention, by using the positioning bracket, the adjusting mechanism and other components in coordination, the steel pipe blank is clamped and then cut, thereby reducing the vibration generated during the processing and improving the cutting quality. At the same time, the clamped steel pipe blank can ensure stability during the grinding process. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the present invention.

[0046] See also Figures 1 to 14 The present invention provides a technical solution: a steel billet cutting device for steel pipe manufacturing, comprising a base 1, a steel billet conveying bracket 2 is fixedly connected to the left side of the top of the base 1, a ring bracket 3 is slidably connected to the middle position of the top of the base 1, and a positioning bracket 4 is slidably connected to the right side of the top of the base 1. It should be noted that the steel billet conveying bracket 2 can convey the steel pipe, and the steel billet conveying bracket 2 uses a conveying bracket in the prior art.

[0047] The surface of the annular bracket 3 is movably connected with a cutting mechanism 5 , and an adjusting mechanism 6 cooperating with the cutting mechanism 5 is movably connected between the surface of the positioning bracket 4 and the annular bracket 3 , and the bottom of the adjusting mechanism 6 is fixedly connected to the top of the base 1 .

[0048] In this embodiment, Figure 1 and Figure 2 As shown, the cutting mechanism 5 includes an annular guide groove 501, which is opened on the left side of the annular bracket 3, and an L-shaped bracket 502 is slidably connected inside the annular guide groove 501, and a transmission motor 503 is fixedly connected to the right side of the L-shaped bracket 502, and a gear rod 504 is fixedly connected to the rotating end of the transmission motor 503, and an adjustment sleeve 505 is movably connected to one end of the gear rod 504. It should be noted that the cross section of the annular guide groove 501 is set to be T-shaped, and a ball is arranged on the surface of the L-shaped bracket 502 close to one end of the annular guide groove 501, and the friction resistance of the L-shaped bracket 502 in the sliding process of the annular guide groove 501 is reduced by the arrangement of the ball.

[0049] The inner ring of the annular bracket 3 is fixedly connected with a gear ring 506, the inner ring of the gear ring 506 meshes with the surface of the gear rod 504, the right side of the annular bracket 3 is fixedly connected with a spiral guide groove 507, the inside of the spiral guide groove 507 is slidably connected with a guide rod 508, and one end of the guide rod 508 is fixedly connected with the side wall of the adjustment sleeve 505. It should be noted that the sliding groove in the middle of the spiral guide groove 507 can be set as a T-shaped cross section similar to the annular guide groove 501, which can ensure the stability of the sliding of the guide rod 508 while enabling the guide rod 508 to slide inside the spiral guide groove 507.

[0050] The inner wall of the adjusting sleeve 505 is provided with an installation groove 509, and the left side of the inner wall of the installation groove 509 is provided with a groove 510, the interior of the groove 510 is fixedly connected with a cutting motor 511, the rotating end of the cutting motor 511 is fixedly connected with a rotating rod 512, the middle part of the rotating rod 512 is fixedly sleeved with a saw disk 513, and the right end of the rotating rod 512 is rotatably connected to the right side of the inner wall of the installation groove 509.

[0051] The grinding plates 514 are movably sleeved on both sides of the rotating rod 512, and the extrusion springs 515 matched with the grinding plates 514 are fixedly connected on both sides of the saw disc 513, and the two extrusion springs 515 correspond to the two grinding plates 514. It should be noted that the extrusion springs 515 press the grinding plates 514 to separate from the saw disc 513, so as to prevent the saw disc 513 from rotating with the grinding plates 514; when the grinding plates 514 are attached to the side walls of the saw disc 513, the saw disc 513 can rotate synchronously with the grinding plates 514.

[0052] The top of the adjustment sleeve 505 is vertically and movably connected with a U-shaped connecting rod 516, and the bottom of the U-shaped connecting rod 516 is symmetrically and fixedly connected with a U-shaped extrusion plate 517, and the two U-shaped extrusion plates 517 correspond to the two grinding plates 514 one by one. The top of the U-shaped connecting rod 516 is fixedly connected with an arc block 518 that matches the adjustment mechanism 6, and the upper part of the U-shaped connecting rod 516 is movably sleeved with a reset spring 519. It should be noted that the reset spring 519 is arranged between the bottom of the arc block 518 and the top of the adjustment sleeve 505; when the arc block 518 is pressed by the adjustment mechanism 6, the arc block 518 moves with the U-shaped connecting rod 516 and the U-shaped extrusion plate 517, so that the U-shaped extrusion plate 517 presses the grinding plate 514 and moves toward the side wall of the saw disk 513.

[0053] The inner wall of the mounting groove 509 is symmetrically fixedly connected with triangular adjustment blocks 520 , and the two triangular adjustment blocks 520 correspond to the two grinding plates 514 one by one. It should be noted that: a triangular magnetic block is fixedly connected to one side of the grinding plate 514 close to the triangular adjustment block 520, and the triangular adjustment block 520 is also set as a magnetic block. The magnetic properties of the triangular magnetic block and the triangular adjustment block 520 are opposite. When the grinding plate 514 is close to the position of the triangular adjustment block 520, it will deflect; when the U-shaped extrusion plate 517 releases the pressure on the grinding plate 514, the extrusion spring 515 elastically restores the pressure on the grinding plate 514 to move in the direction of the corresponding triangular adjustment block 520. At this time, the side wall of the grinding plate 514 contacts the inclined surface of the triangular adjustment block 520, so that the grinding plate 514 rotates on the surface of the rotating rod 512 and overlaps the top surface of the triangular adjustment block 520, avoiding the reset triangular adjustment block 520 from extending from the bottom of the mounting groove 509; when the grinding plate 514 is in contact with the saw disk 513, the triangular adjustment block 520 releases the restriction on the grinding plate 514 to avoid interference.

[0054] In this embodiment, Figures 1 to 14 As shown, a slide groove is provided at one end of the adjustment sleeve 505 close to the gear rod 504, a slider is fixedly connected to one end of the gear rod 504, the gear rod 504 is slidably connected to the inside of the slide groove through the slider, and the cross section of the slide groove is set to be T-shaped. It should be noted that: the slider is set to be circular, and the end of the gear rod 504 is slidably connected to the inside of the T-section slide groove through a circular slider, so that the gear rod 504 can slide stably in the slide groove, while ensuring the stability of the adjustment sleeve 505 and the gear rod 504 during the sliding process, and avoiding the adjustment sleeve 505 and the gear rod 504 from separating; when the gear rod 504 rotates, the rotating gear rod 504 and the L-shaped bracket 502 move along the trajectory of the annular guide groove 501 on the side wall of the annular bracket 3, so that the adjustment sleeve 505 rotates along the circumference of the annular bracket 3 with the guide rod 508, and during the movement of the guide rod 508 along the trajectory of the spiral guide groove 507, the slide groove on the side wall of the adjustment sleeve 505 cooperates with the slider at one end of the gear rod to slide, so that the adjustment sleeve 505 gradually moves toward the center of the annular bracket 3 with the saw disk 513.

[0055] In this embodiment, Figures 1 to 14 As shown, both sides of the middle of the saw disc 513 are fixedly connected with spring sleeves, a squeeze spring 515 is fixedly connected inside the spring sleeve, and an squeeze ring is fixedly connected to one end of the squeeze spring 515 away from the spring sleeve, and the side wall of the squeeze ring overlaps the side wall of the adjacent grinding plate 514. It should be noted that the squeeze ring is movably sleeved on the surface of the rotating rod 512, and the squeeze ring is arranged to prevent the saw disc 513 from rotating with the grinding plate 514 through the squeeze spring 515 during the rotation process.

[0056] The grinding plate 514 is provided with an anti-skid pad on one side opposite to the adjacent spring sleeve. It should be noted that the friction resistance between the grinding plate 514 and the extrusion ring is increased, and when the grinding plate 514 fits with the spring sleeve of the side wall of the saw disc 513, the saw disc 513 rotates synchronously with the grinding plate 514; and the anti-skid pad can be configured to cooperate with the tooth groove and the tooth block in a plug-in manner to achieve synchronous rotation of the grinding plate 514 and the saw disc 513.

[0057] In this embodiment, Figures 1 to 14 As shown, the side of the U-shaped extrusion plate 517 close to the grinding plate 514 is set as an inclined surface, and the center of the U-shaped extrusion plate 517 and the rotating rod 512 are set on the same straight line. It should be noted that when the U-shaped extrusion plate 517 moves downward, it will press the grinding plate 514 to move toward the spring sleeve, and the U-shaped extrusion plate 517 will not interfere with the rotating rod 512.

[0058] In this embodiment, Figures 1 to 14 As shown, the adjustment mechanism 6 includes an electric telescopic rod 601, and the electric telescopic rod 601 is set to two, and the two electric telescopic rods 601 are symmetrically fixedly connected to the right side of the top of the base 1, and the movable ends of the two electric telescopic rods 601 are respectively fixedly connected to the two sides of the positioning bracket 4;

[0059] Circular holes 602 are provided on both sides of the lower part of the annular bracket 3, and the left ends of the two electric telescopic rods 601 are respectively movably inserted into the inside of the two circular holes 602, and the left end of the electric telescopic rod 601 passes through the annular bracket 3 and is fixedly connected with a retaining ring 603, and the left side of the electric telescopic rod 601 is fixedly sleeved with a limiting ring 604, and the side wall of the limiting ring 604 overlaps the side wall of the annular bracket 3. It should be noted that: when the electric telescopic rod 601 extends to the left to the extreme position, the annular bracket 3 is limited to the current position under the restriction of the limiting ring 604, and the left side of the annular bracket 3 overlaps the limiting block on the base 1.

[0060] A cone ring adjustment bracket 605 matched with the cutting mechanism 5 is arranged between the annular bracket 3 and the positioning bracket 4, and the bottom of the cone ring adjustment bracket 605 is fixedly connected to the top of the base 1. It should be noted that the inner ring of the cone ring adjustment bracket 605 is set as a conical surface. When the electric telescopic rod 601 is retracted, the annular bracket 3 is pulled to move to the right through the retaining ring 603. At this time, the arc block 518 on the annular bracket 3 contacts the inner ring of the cone ring adjustment bracket 605 and is pressed to move the U-shaped connecting rod 516 to the inside of the adjustment sleeve 505.

[0061] In this embodiment, Figures 1 to 14 As shown, the right side of the positioning bracket 4 is symmetrically fixedly connected with an electric push rod, and the movable end of the electric push rod is fixedly connected with an arc clamping block. It should be noted that the electric push rod with the arc clamping block clamps the steel pipe billet during the cutting process to reduce the vibration generated during the cutting process of the steel pipe billet.

[0062] A discharge hole is provided in the middle of the positioning bracket 4, a discharge guide plate is provided inside the discharge hole, a support leg is fixedly connected to the bottom of the discharge guide plate, and the bottom of the support leg is fixedly connected to the top of the base 1. It should be noted that: after the steel pipe blank is cut and polished, the arc-shaped clamping block releases the clamping of the steel pipe blank, so that the cut steel pipe blank is discharged from the discharge guide plate position.

[0063] In this embodiment, Figures 1 to 14 As shown, a method for using a steel billet cutting device for steel pipe manufacturing comprises the following steps:

[0064] S1. When in use, start the steel billet conveying bracket 2 to convey the steel pipe billet toward the positioning annular bracket 3 and the positioning bracket 4. When the steel pipe billet moves to the position of the positioning bracket 4, start the electric push rod with the arc clamping block to clamp the steel pipe billet, then start the cutting motor 511 to rotate the saw disk 513, and start the transmission motor 503 to rotate the gear rod 504, so that the gear rod 504 is meshed with the gear ring 506 on the annular bracket 3 for transmission;

[0065] S2. As the gear rod 504 rotates, the L-shaped bracket 502 slides along the track of the annular guide groove 501 on the side wall of the annular bracket 3, and the gear rod 504 that rotates and moves in a circle along the annular guide groove 501 moves synchronously with the adjusting sleeve 505. During this process, the guide rod 508 on the adjusting sleeve 505 slides along the track of the spiral guide groove 507, so that the adjusting sleeve 505 moves in a circle along the annular bracket 3 and gradually moves toward the center of the annular bracket 3. The rotating saw disc 513 cuts the steel pipe blank during the synchronous movement of the adjusting sleeve 505.

[0066] S3, when the steel pipe billet is cut, the transmission motor 503 is turned off, and the electric telescopic rod 601 is started to move the positioning bracket 4 to the right, so that the steel pipe billet clamped on the positioning bracket 4 moves to the right, and at the same time, the electric telescopic rod 601 pulls the annular bracket 3 to move to the right through the retaining ring 603. At this time, the adjustment sleeve 505 moves to the extreme position toward the center of the annular bracket 3, and the arc block 518 at the end of the adjustment sleeve 505 that moves to the right contacts the inner circle of the conical ring adjustment bracket 605 on the top of the base 1. The arc block 518 is compressed and moves with the U-shaped connecting rod 516 toward the inside of the adjustment sleeve 505. At this time, the U-shaped extrusion plate 517 on the U-shaped connecting rod 516 presses against the corresponding side wall position of the grinding plate 514, so that the grinding plate 514 translates on the rotating rod 512 and fits with the side wall of the saw disk 513. The rotating saw disk 513 drives the grinding plate 514 to rotate synchronously, so that the grinding plates 514 on both sides of the saw disk 513 grind the ends of the steel pipe billet between the steel billet conveying bracket 2 and the positioning bracket 4 respectively.

[0067] S4. After the steel pipe blank is polished, the electric telescopic rod 601 is reset. At this time, the reset spring 519 brings the U-shaped connecting rod 516 to reset, and the transmission motor 503 brings the gear rod 504 to reverse, so that the adjustment sleeve 505 is reset to prepare for the next steel pipe blank cutting.

8. The method for using the steel billet cutting device for steel pipe manufacturing according to claim 7 comprises the following steps: S1. When in use, the steel billet conveying bracket (2) is started to convey the steel pipe billet toward the positioning annular bracket (3) and the positioning bracket (4). When the steel pipe billet moves to the position of the positioning bracket (4), the electric push rod is started to clamp the steel pipe billet with the arc clamping block, and then the cutting motor (511) is started to rotate the saw disc (513). At the same time, the transmission motor (503) is started to rotate the gear rod (504), so that the gear rod (504) and the gear ring (506) on the annular bracket (3) are meshed and transmitted; S2. As the gear rod (504) rotates, the L-shaped bracket (502) slides along the track of the annular guide groove (501) on the side wall of the annular bracket (3), and the gear rod (504) that rotates and moves in a circle along the annular guide groove (501) moves synchronously with the adjusting sleeve (505). During this process, the guide rod (508) on the adjusting sleeve (505) slides along the track of the spiral guide groove (507), so that the adjusting sleeve (505) moves in a circle along the annular bracket (3) and gradually moves toward the center of the annular bracket (3). The rotating saw disc (513) cuts the steel pipe blank during the synchronous movement of the adjusting sleeve (505); S3. After the steel tube billet is cut, the transmission motor (503) is turned off, and the electric telescopic rod (601) is started to move the positioning bracket (4) to the right, so that the steel tube billet clamped on the positioning bracket (4) moves to the right. At the same time, the electric telescopic rod (601) pulls the annular bracket (3) to move to the right through the retaining ring (603). At this time, the adjustment sleeve (505) moves to the limit position toward the center of the annular bracket (3), and the arc block (518) at the end of the adjustment sleeve (505) that moves to the right contacts the inner ring of the conical ring adjustment bracket (605) at the top of the base (1), so that the arc block (518) at the end of the adjustment sleeve (505) that moves to the right contacts the inner ring of the conical ring adjustment bracket (605) at the top of the base (1). The block (518) is compressed and moves with the U-shaped connecting rod (516) toward the inside of the adjusting sleeve (505). At this time, the U-shaped extrusion plate (517) on the U-shaped connecting rod (516) presses against the corresponding side wall position of the grinding plate (514), so that the grinding plate (514) translates on the rotating rod (512) and fits with the side wall of the saw disk (513). The rotating saw disk (513) drives the grinding plate (514) to rotate synchronously, so that the grinding plates (514) on both sides of the saw disk (513) grind the ends of the steel pipe blanks between the steel billet conveying bracket (2) and the positioning bracket (4) respectively. S4. After the steel tube blank is polished, the electric telescopic rod (601) is reset, and the reset spring (519) brings the U-shaped connecting rod (516) to reset, and the transmission motor (503) brings the gear rod (504) to reverse, so that the adjustment sleeve (505) is reset to prepare for the next steel tube blank cutting.
