Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steel pipe processing equipment, in particular to a seamless steel pipe cutting and polishing production line. BACKGROUND

[0002] Seamless steel pipe is a hollow steel material formed by solid pipe blank perforation rolling, and its core feature is that there is no welding seam on the surface, and it has a hollow section and high strength characteristics. Compared with solid steel such as round steel, seamless steel pipe is lighter in weight at the same bending and torsional strength, and is a typical representative of economic section steel. Its material covers carbon steel, alloy steel and stainless steel, and can be divided into round pipes and special-shaped pipes (such as square and oval pipes) according to the shape, and can be divided into boiler pipes, geological pipes and oil pipes according to the purpose.

[0003] During the production of seamless steel pipe, it needs to be cut and end face polished. Generally, the seamless steel pipe is clamped, and then the cutting mechanism is pushed down to cut the seamless steel pipe. After the cutting is finished, the workers need to manually transfer the cut seamless steel pipe to the polishing mechanism for end face polishing. When polishing the end face, the steel pipe to be polished needs to be clamped again, and then the end face is polished.

[0004] This way is more complicated, and the cutting precision is low when the cutting mechanism is lowered. When the positioning of the seamless steel pipe is unstable, the cutting precision will be seriously affected, and the polishing workload will be increased. Moreover, when the seamless steel pipe is polished, the re-clamping and positioning method seriously increases the workload and cannot realize the rapid cutting and polishing of the seamless steel pipe.

[0060] In one embodiment of the present application, referring to Figures 1-9 , the second clamping assembly 4 comprises a first rotating rod 401 rotatably arranged in the shell 1, one end of the first rotating rod 401 away from the laser cutting assembly 3 is provided with a first guide sliding groove 4011, and the other end of the first rotating rod 401 close to the laser cutting assembly 3 is provided with a first mounting frame 402.

The third electric cylinder 408 is connected between the inner wall of the first mounting frame 402 or the second mounting frame 409 and the connecting plate 407.

[0061] The switching assembly 6 comprises a rotating disc 605 rotatably arranged on the side wall of the shell 1. The rotating disc 605 is connected to the end of the first rotating rod 401 penetrating the side wall of the shell 1. The rotating groove 606 is provided with a rotating groove 606 away from one side of the shell 1. The rotating groove 606 comprises a plurality of circumferentially distributed circular grooves. The mounting frame 601 is mounted on the side wall of the shell 1. The cutting motor 602 is mounted on the mounting frame 601. The output shaft of the cutting motor 602 is connected with the rotating gear 603 movably cooperating with the rotating groove 606. The rotating gear 603 is in sliding cooperation with the uppermost circular groove. One end of the rotating gear 603 is connected with the abutting rod 607. The outer end of the rotating disc 605 is circumferentially provided with a plurality of abutting rods 607.

[0062] In the embodiment, the initial state is that the included angle between the two side clamping plates 404 corresponding to the opening 105 is at a maximum, the included angle between the two side clamping plates 404 corresponding to the discharge port 103 is at a maximum, the included angle between the two side clamping plates 404 corresponding to the polishing assembly 7 is at a minimum, the rotating residual wheel 603 is matched with the rotating groove 606, and the angle of the rotating disc 605 is fixed.

[0063] According to the distance measuring assembly 8 and the required cutting length, the position of the interval adjusting assembly 5 is adjusted, the steel pipe 10 to be cut is placed on the first supporting arc plate 201, and the steel pipe 10 to be cut is pushed towards the interval adjusting assembly 5, so that one end of the steel pipe 10 to be cut away from the laser cutting assembly 3 abuts against the interval adjusting assembly 5, the third electric cylinder 408 corresponding to the opening 105 and located on the first mounting frame 402 and the second mounting frame 409 respectively is elongated, the third electric cylinder 408 drives the connecting plate 407 to move synchronously, the hinged rod 406 and the side clamping plate 404 are connected, and the side clamping plate 404 and the rotating seat 405 are matched and rotated to drive the corresponding two side clamping plates 404 to rotate towards the middle, so that the included angle between the two side clamping plates 404 is reduced, and the two side clamping plates 404 clamp the steel pipe 10 to be cut through the matching mode with the second supporting arc plate 403, so as to facilitate the stable cutting of the steel pipe 10 to be cut.

[0064] When the cutting of the steel pipe 10 to be cut ends, the cutting motor 602 drives the rotating residual wheel 603 to rotate clockwise, and the rotating residual wheel 603 drives the push rod 604 to rotate synchronously. In the process of upward rotation of the push rod 604, the push rod 604 does not contact the abutting rod 607 on the left. When the push rod 604 rotates to the highest point, the push rod 604 contacts the abutting rod 607 at the highest point. At this time, the rotating residual wheel 603 does not cooperate with the uppermost circular groove. In the process of downward rotation of the push rod 604, the push rod 604 drives the rotating disc 605 to rotate clockwise by contacting the abutting rod 607 and by the rotating disc 605 rotating with the side wall of the shell 1. When the push rod 604 rotates downward to a certain angle, the circular groove originally on the left will rotate upward. At this time, the rotating residual wheel 603 will slide with the circular groove again. When the rotating residual wheel 603 continues to rotate, the rotating residual wheel 603 drives the rotating disc 605 to continue to rotate upward by sliding with the circular groove. When the push rod 604 does not contact the connecting plate 407, at this time, the abutting rod 607 originally on the left rotates to the uppermost position, the intermittent rotation of the rotating disc 605 can be realized, the switching of the workstations can be realized, that is, the orderly circulation switching of the cutting workstation on the uppermost position-the polishing workstation on the right-the discharging workstation on the left-the cutting workstation on the uppermost position, which avoids the manual transfer of the workpiece to the polishing machine for polishing treatment after the workpiece is cut, reduces the work burden of the workers, saves the processing time, and improves the processing efficiency of the workpiece.

[0065] Specifically, when the steel pipe 10 to be cut is in the cutting station, the steel pipe 10 to be cut is clamped by the cooperation of the two side clamping plates 404 and the second support arc plate 403, so as to facilitate the cutting of the steel pipe 10 to be cut by the laser cutting assembly 3. After the steel pipe 10 to be cut is cut, the cut pipe is the steel pipe 11 to be polished. The cutting motor 602 is driven to rotate clockwise by the mounting frame 601, so that the rotating disc 605 rotates clockwise. The rotating disc 605 drives the steel pipe 11 to be polished to rotate clockwise synchronously through the connection with the first rotating rod 401 and the connection of the first rotating rod 401 with the first mounting frame 402 and the second mounting frame 409, so that the steel pipe 11 to be polished is rotated to the polishing assembly 7. The two ends of the steel pipe 11 to be polished are polished by the polishing assembly 7. At the same time, the laser cutting assembly 3 can cut the steel pipe 10 to be cut located in the cutting station again. When the cutting of the steel pipe 10 to be cut and the polishing of the two ends of the polishing assembly 7 are completed, the cutting motor 602 is driven to continue rotating clockwise by the mounting frame 601, so that the newly cut steel pipe 11 to be polished is rotated to the polishing assembly 7. The steel pipe 11 to be polished originally located in the polishing assembly 7 is rotated to directly above the discharge port 103. The third electric cylinder 408 corresponding to the discharge port 103 is controlled to retract, the connecting plate 407 is driven to move synchronously by the third electric cylinder 408, the two side clamping plates 404 corresponding to the discharge port 103 are driven to rotate outward by the connecting plate 407 through the connection with the hinged rod 406 and the rotation of the rotating seat 405 and the side clamping plate 404, so that the included angle between the two side clamping plates 404 increases, and the clamping of the corresponding steel pipe 11 to be polished is released. The steel pipe 11 to be polished will pass through the discharge port 103 under the action of its own gravity, realizing the discharge of the cut and polished pipe.
