Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe production equipment, and more specifically, to a welded pipe blanking machine. Background Art

[0002] A welded pipe is formed by gradually bending a long strip of metal sheet to close both sides to form a tubular shape, and then welding the closed part to form a metal pipe. After welding, it is cut, and the long metal pipe is cut into equal lengths, and finally becomes welded pipes of the same length. A welded pipe blanking machine is required when blanking the welded pipes from the production line.

[0003] In the process of technological development, there is a kind of welded pipe blanking machine that first aligns the welded pipes transported by the conveyor belt after cutting, and then transports them horizontally so that the welded pipes fall into the hopper. However, in the actual production process, when the welded pipes are cut, metal chips will enter the inside of the welded pipes. During the blanking process, the two ends of the welded pipes always remain at the same height, so that the chips always stay inside the welded pipes and need to be dumped after the welded pipes are bundled.

[0004] Therefore, in order to solve the above technical problems, this application proposes a welded pipe blanking machine. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a welded pipe blanking machine.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: The welded pipe blanking machine includes a blanking channel for receiving the welded pipes after cutting and grinding the burrs on the cut ends of the welded pipes; a debris separation assembly arranged at the discharge port of the blanking channel for cleaning the debris inside the welded pipes; and an installation platform for installing the debris separation assembly.

[0007] Preferably, the debris separation assembly includes a motor, and a rotating bin is arranged at the front end of the output shaft of the motor. The motor drives the rotating bin to rotate so that the opening of the rotating bin faces the discharge port of the blanking channel to receive the welded pipes, and the opening of the rotating bin rotates away from the discharge port of the blanking channel to release the welded pipes;

[0008] The debris separation assembly further includes a slag pushing assembly for pushing out the debris inside the welded pipes carried on the rotating bin.

[0009] Preferably, the rotating bin is divided into an inner layer and an outer layer, and there is a gap between the two layers. The outer layer is an outer arc plate, and the inner layer is a slag filtering plate. The slag filtering plate is provided with slag filtering grooves for filtering debris;

[0010] On the side of the outer arc plate and the slag filter plate away from the blanking channel, a guard plate is sealed, while the other side is open, so that when the rotating bin turns to the opening of the blanking channel, debris can slide out from the gap opening between the outer plate and the slag filter plate, and prevent the debris from sliding out together with the welded pipe when the rotating bin feeds the welded pipe.

[0011] Preferably, the opening on the side of the slag filter tank close to the outer arc plate is smaller than the opening on the side away from the outer arc plate to prevent debris from returning into the slag filter plate.

[0012] Preferably, the slag pushing assembly includes a cylinder. A pushing plate is arranged at the front end of the piston rod of the cylinder. A guiding cone is arranged at the front end of the pushing plate. The guiding cone is arranged in a sharp conical shape to gradually make the inner wall of the welded pipe fit the surface of the pushing plate when advancing forward.

[0013] Preferably, the blanking channel includes a blanking bin for receiving the welded pipe after cutting. A blanking slope plate is arranged at the discharge port of the blanking bin. The blanking slope plate is used to guide the welded pipe to slide down. Baffles are arranged on both sides of the blanking slope. The baffles are used to grind the cut ends of the welded pipe from both ends to remove the burrs at the cut ends.

[0014] Preferably, a chip discharge port is opened on the installation platform for discharging the discharged debris, and a blanking port is also opened on the installation platform for discharging the welded pipe transferred out by the rotating bin;

[0015] The cylinder and the motor are installed on the installation platform. The rotating bin is rotatably installed on the installation platform through a bearing seat.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. In the utility model, by arranging the rotating bin and the slag pushing assembly, when feeding the welded pipe, the rotating bin can be used to transfer and feed the welded pipe individually, and the slag pushing assembly is extended into the welded pipe to push out the debris in the welded pipe, avoiding the work of tilting the bundled welded pipes;

[0018] 2. In the utility model, by setting the rotating bin into two layers inside and outside to filter the debris, when the rotating bin rotates to pick up the welded pipe, the debris filtered last time is dumped. The rotating bin rotates to the other side and then feeds the welded pipe, realizing the technical effect of separating the feeding of the welded pipe and the debris, and avoiding the secondary separation of the debris and the welded pipe.

[0033] As Figures 1-3 shown, a welded pipe feeding machine includes a feeding channel 1 for receiving the cut welded pipe and deburring the burrs on both ends of the cut of the welded pipe, a chip separation assembly 2 arranged at the outlet of the feeding channel 1 for cleaning the chips in the welded pipe, and an installation platform 3 for installing the chip separation assembly 2;

[0034] The feeding channel 1 includes a feeding bin 11 for receiving the cut welded pipe, a feeding slope plate 12 is arranged at the outlet of the feeding bin 11, the feeding slope plate 12 is used to guide the welded pipe to slide down, and baffles 13 are arranged on both sides of the feeding slope, and the baffles 13 are used to deburr the cut of the welded pipe from both ends to remove the burrs at the cut;

[0035] The cut welded pipe that drops from the feeding bin 11 enters and slides along the feeding slope plate 12. During the process, the two ends of the welded pipe slide and rub against the baffle 13, and the burrs at the cut of the welded pipe fall off due to the friction. Part of them enter the inside of the welded pipe, and the other part slides down along the feeding slope plate 12;

[0036] The debris separation assembly 2 includes a motor 21. A rotating bin 22 is provided at the front end of the output shaft of the motor 21 to drive the rotating bin 22 to rotate through the motor 21, so that the opening of the rotating bin 22 faces the discharge port of the blanking channel 1 to receive the welded pipe, and the opening of the rotating bin 22 rotates away from the discharge port of the blanking channel 1 to release the welded pipe;

[0037] The rotating bin 22 only transfers one welded pipe each time. After picking up one welded pipe, the opening of the rotating bin 22 gradually deviates from the discharge port of the blanking channel 1. When the cutting speed is faster than the operating speed of the rotating bin 22, the welded pipes will be arranged upward along the discharge port of the blanking channel 1. When the rotating bin 22 completes one transfer, when the opening faces the discharge port of the blanking channel 1 again, the welded pipes will automatically fall under the action of gravity to the next welded pipe;

[0038] The debris separation assembly 2 includes a slag pushing assembly 23 for pushing out the debris in the welded pipe carried on the rotating bin 22,

[0039] The slag pushing assembly 23 includes a cylinder 231. A pushing plate 232 is provided at the front end of the piston rod of the cylinder 231. A guiding cone 233 is provided at the front end of the pushing plate 232. The guiding cone 233 is set to be pointed conical to gradually fit the inner wall of the welded pipe to the surface of the pushing plate 232 when advancing forward; after the rotating bin 22 receives the welded pipe, it gradually rotates to the side away from the blanking channel 1, and the welded pipe rolls in the rotating bin 22, and its position is not fixed and may not coincide with the axis of the piston rod of the cylinder 231. At this time, when the cylinder 231 brakes the piston rod to push forward, the tip of the guiding cone 233 is relatively small and easier to insert into the welded pipe. During the gradual forward pushing process, the outside of the guiding cone 233 will directly push the inner wall of the welded pipe, making the central axis of the welded pipe gradually collinear with the axis of the piston rod of the cylinder 231, achieving the effect of correction. Finally, the pushing plate 232 enters the welded pipe to push out the debris in the welded pipe;

[0040] Therefore, by setting the rotating bin 22 and the slag pushing assembly 23, when blanking the welded pipe, the rotating bin 22 can be used to transfer and blank the welded pipe individually, and the slag pushing assembly 23 can be extended into the welded pipe to push out the debris in the welded pipe, avoiding the work of the welded pipes tipping over after bundling;

[0041] The rotating bin 22 is divided into an inner layer and an outer layer, and there is a gap between the two layers. The outer layer is an outer arc plate 221, and the inner layer is a slag filtering plate 223. Slag filtering grooves 224 are provided on the slag filtering plate 223 for filtering debris. After the debris is pushed out of the welded pipe, it will leak downward along the slag filtering grooves 224 into the gap between the slag filtering plate 223 and the outer arc plate 221;

[0042] On the side of the outer arc plate 221 and the filter residue plate 223 away from the blanking channel 1, a guard plate 225 is sealed, while the other side is open, so that when the rotating bin 22 turns towards the opening of the blanking channel 1, debris can slide out from the gap opening between the outer plate and the filter residue plate 223, and prevent the debris from sliding out together with the welded pipe when the rotating bin 22 discharges the welded pipe;

[0043] The opening on the side of the filter residue tank 224 close to the outer arc plate 221 is smaller than the opening on the side away from the outer arc plate 221, to prevent debris from returning into the filter residue plate 223;

[0044] When the rotating bin 22 continues to rotate away from the blanking channel 1, the filtered debris slides in the gap, and the opening on the side of the filter residue tank 224 facing the gap is smaller, forming a certain blockage to the debris, reducing the possibility of the debris sliding out from it, and when the rotation angle is too large, the guard plate 225 forms an occlusion to the debris in the gap from this side, preventing it from sliding out;

[0045] Therefore, by setting the rotating bin 22 into two layers inside and outside to filter the debris, when the rotating bin 22 rotates to pick up the welded pipe, the debris filtered last time is dumped, and the rotating bin 22 rotates to the other side to discharge the welded pipe, achieving the technical effect of separate discharging of the welded pipe and the debris, and avoiding the secondary separation of the debris and the welded pipe;

[0046] A chip outlet 31 is provided on the installation platform 3 for discharging the discharged debris, and a blanking port 32 is also provided on the installation platform 3 for discharging the welded pipe transferred out by the rotating bin 22;

[0047] The cylinder 231 and the motor 21 are installed on the installation platform 3, and the rotating bin 22 is rotatably installed on the installation platform 3 through a bearing seat.

[0048] The above is only a preferred embodiment of the present invention, and does not impose any form of limitation on the present invention; any ordinary technician in the industry can smoothly implement the present invention as shown in the accompanying drawings of the specification and the above; however, any minor changes, modifications and evolutions made by those familiar with the professional technology within the scope of the technical solution of the present invention by using the technical content disclosed above are equivalent embodiments of the present invention; at the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention still fall within the protection scope of the technical solution of the present invention.
