Description

Technical Field

[0001] The invention relates to the field of pipe processing, in particular to a seamless steel pipe production blanking device. Background Art

[0002] Seamless steel pipe is made by perforating a whole round steel. There is no weld on the surface of the steel pipe, which is called seamless steel pipe.

[0003] When cutting seamless steel pipes, a rotary cutting knife is usually used to directly cut the seamless steel pipes. When the rotary cutting knife is cutting the seamless steel pipes, the seamless steel pipes are subjected to a large downward pressure from the cutting knife, and the pipe mouth is easily deformed during cutting, thereby affecting the normal use of the seamless steel pipes after cutting.

[0004] When cutting seamless steel pipes, the cut part needs to be cooled. Usually, coolant is used to cool the cut part directly. However, the rotary cutting knife will bring coolant and adhered debris into the interior of the seamless steel pipe cavity during operation, which is difficult to clean and affects the cleanliness of the interior of the seamless steel pipe.

[0005] The above contents are only used to assist in understanding the technical solution of the present invention, and do not constitute an admission that the above contents are the closest prior art. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a seamless steel pipe production blanking device which can avoid deformation of the pipe mouth during cutting.

[0007] To achieve the above-mentioned purpose, the technical solution of the present invention is implemented as follows, including a workbench, a support member, a clamping member, a cutting member, a pushing member and a sleeve, wherein the support member is arranged on the workbench, the pushing member is located on one side of the support member on the workbench, the cutting member is arranged on the other side of the support member on the workbench, a discharge trough is arranged on the other side of the cutting member, the sleeve is arranged on the side wall of one side of the discharge trough, a third cylinder is arranged in the sleeve, and a limiting roller is connected to one side of the third cylinder.

[0008] Furthermore, the seamless steel pipe is placed on the support, and then the limiting roller is transported to the specified position by the third cylinder, and the seamless steel pipe is pushed to move by the pushing member. After one end of the seamless steel pipe is sleeved on the limiting roller and reaches the specified position, the clamping member moves down to press the seamless steel pipe downward and limit it, and the cutting member starts to cut the seamless steel pipe. While the clamping member presses the seamless steel pipe downward and limits it, it drives the seamless steel pipe on the support to rotate, thereby cooperating with the cutting member to complete the cutting of the seamless steel pipe. During cutting, the limiting roller located in the cutting chamber of the seamless steel pipe bears the downward pressure generated during cutting, thereby avoiding deformation of the incision of the seamless steel pipe during cutting. After cutting is completed, the third cylinder drives the limiting roller to move into the casing, and at the same time drives the cut seamless steel pipe to be discharged from the discharge chute.

[0009] Furthermore, the support member includes two support frames symmetrically arranged on the workbench, connecting blocks are arranged on both sides of the support frames, and rotating rollers are rotatably installed between the connecting blocks; with this design, the seamless steel pipe is supported by two rotating rollers, so that when the seamless steel pipe is pressed down and limited by the clamping member, it will not restrict the rotation.

[0010] Furthermore, the clamping member includes a lifting frame arranged on both sides of the workbench, a movable connecting frame is movably arranged in the lifting frame, a first cylinder is installed at the bottom of the movable connecting frame, and a transmission belt is installed between the movable connecting frames; in this design, the movable connecting frame is driven downward by the first cylinder, and the seamless steel pipe on the rotating roller is clamped and limited by the transmission belt installed between the movable connecting frames, and the seamless steel pipe can be driven to rotate by the driving of the rotating roller through the operation of the transmission belt.

[0011] Furthermore, the cutting piece includes a cutting frame arranged on the workbench, a cutting knife is installed on the top of the cutting frame, and a coolant nozzle is arranged on one side of the cutting knife. With this design, the seamless steel pipe is cut by the cutting knife, and the cutting part is cooled by the coolant nozzle. During the cutting process, the transmission belt drives the seamless steel pipe to rotate and cooperate with the cutting knife to cut the seamless steel pipe.

[0012] Furthermore, the pushing member includes a mounting frame arranged on a side wall of one side of the workbench, a second cylinder is installed on one side of the mounting frame, and a push plate is installed on one end of the second cylinder; in this design, the push plate is driven to move by the second cylinder, thereby pushing the seamless steel pipe on the support member to move through the push plate.

[0013] Furthermore, the limiting roller includes a connecting tube, one end of the connecting tube is connected to the third cylinder, and the other end of the connecting tube is provided with a cutting groove, one side of the cutting groove on the connecting tube is sleeved with a first supporting shaft, and the other side of the cutting groove on the connecting tube is sleeved with a second supporting shaft, a limiting block is arranged at the middle bottom of the connecting tube, and the bottom of the connecting tube connected to the third cylinder is connected to a chip collection box; in this design, the first supporting shaft and the second supporting shaft are inserted into the seamless steel pipe cutting chamber during cutting, so that the downward pressure generated by the cutting knife on the seamless steel pipe during cutting is mainly borne by the first supporting shaft and the second supporting shaft, thereby effectively avoiding deformation of the pipe mouth during cutting. With the use of the limiting block, after the limiting roller is pushed to the working position by the third cylinder, the seamless steel pipe is pushed to move by the pushing member, and the side wall of the seamless steel pipe stops moving after contacting the limiting block, and the position of the limiting block can be changed according to the cutting length.

[0014] Furthermore, a movable groove is provided at the bottom of the sleeve, a push pipe is provided on one side of the sleeve located in the discharge trough, and a groove adapted to the limit block is provided on the push pipe; with this design, after the cutting of the seamless steel pipe is completed, the third cylinder drives the limit roller to move into the sleeve, and the opening of the movable groove and the groove can prevent the limit block from affecting the movement of the limit roller into the sleeve, and the push pipe is used to push the seamless steel pipe cut on the limit roller down and drop it into the discharge trough.

[0015] Furthermore, a fan is provided in the chip collection box; with such a design, when the fan works, the coolant and debris around the cutting groove are sucked into the connecting pipe by suction, and then the coolant and debris are brought into the chip collection box, thereby preventing the coolant and debris from contaminating the inner wall cavity of the seamless steel pipe.

[0016] Furthermore, the second supporting shaft is tapered on the side away from the cutting groove; this design makes it easy for the seamless steel pipe to be mounted on the limiting roller under the push of the pushing member, and through the use of the second supporting shaft, after the cutting is completed, when the limiting roller is taken out of the seamless steel pipe, the second supporting shaft processes the burrs and debris on the inner wall of the cut part of the seamless steel pipe during the movement.

[0017] The beneficial effects of the present invention are embodied in: The present invention, through the use of limiting rollers, when cutting the seamless steel pipe, the first supporting shaft and the second supporting shaft are placed on both sides of the chamber where the seamless steel pipe is cut. The downward pressure generated by the cutting knife on the seamless steel pipe when cutting is mainly borne by the first supporting shaft and the second supporting shaft, thereby effectively avoiding deformation of the pipe mouth during cutting.

[0018] The present invention arranges a fan in the chip collecting box. When the fan works, the coolant and debris around the cutting groove are sucked into the connecting pipe by suction, and then the coolant and debris are brought into the chip collecting box, thereby preventing the coolant and debris from contaminating the inner wall cavity of the seamless steel pipe. Moreover, by using the first supporting rotating shaft and the second supporting rotating shaft, the coolant and debris can be prevented from entering the inner wall cavity of the seamless steel pipe.

[0019] The present invention uses the second supporting rotating shaft, and after cutting is completed, when the limiting roller is taken out from the seamless steel pipe, the second supporting rotating shaft processes the burrs and debris on the inner wall of the cut portion of the seamless steel pipe during movement.
