Description

Technical Field

[0001] This utility model relates to the field of pipe processing technology, and in particular to a tooling for cutting the end of an oil pipe. Background Technology

[0002] After prolonged use, oil pipes may become damaged due to corrosion and other reasons, rendering them unusable for production. In such cases, the pipes need to be replaced. Simply scrapping the replaced pipes would be a waste of resources. The common practice is to reprocess the pipes to restore their usability. During this reprocessing, the damaged ends of the pipes are typically cut off. Because of the pipe's length, it's usually placed on a conveyor track. After the damaged sections are cut off, the pipe is transported away. However, in practice, the cut sections often fall directly onto the conveyor track, requiring manual cleaning. Furthermore, different pipes vary significantly in length, and simultaneously sawing both ends would require an excessively large adjustment range for the sawing equipment, making the operation inconvenient. Utility Model Content

[0003] In view of the shortcomings of the above-mentioned prior art, this application provides a tooling for cutting oil pipe ends, which clamps the oil pipe ends and facilitates the transfer of the oil pipe ends, and has strong practicality.

[0004] To achieve the above objectives, the present invention employs the following technology:

[0005] A tooling for cutting oil pipe ends includes: a conveying track, a positioning assembly, and a clamping assembly.

[0006] There are two conveying tracks, arranged sequentially along their respective conveying directions, for conveying oil pipes; there are two positioning components, each located above the conveying tracks, including two support plates respectively located on both sides of the conveying tracks and movable in the vertical direction, with multiple pressure blocks above the support plates along their length direction for limiting the oil pipes; the clamping component includes a lifting frame located between the conveying tracks and movable in the vertical direction, with multiple baffles arranged at intervals on both sides of the lifting frame along its own circumference and moving synchronously in its own radial direction, with a clamping block on the side of the baffle away from the center of the lifting frame, and the lower clamping block movable along the thickness direction of the lifting frame for clamping the end of the oil pipe.

[0007] Furthermore, two horizontal plates are provided on both sides of the lifting frame, and multiple protrusions are provided on the sides of the horizontal plates along their length. Some of the protrusions have through rods on their bottom surfaces, which are inserted into the support plates. When in use, the protrusions abut against the top surface of the support plates.

[0008] Furthermore, the side of the pressure block facing the starting end of the conveying track is a downward slope, and both ends are provided with connecting plates. The connecting plates are sleeved on the vertical rod, the vertical rod is installed on the support plate, the upper end of the vertical rod is provided with a retaining ring, and a first spring is sleeved on the vertical rod. The two ends of the first spring abut against the connecting plate and the retaining ring respectively, and are always in a compressed state.

[0009] Furthermore, the bottom surface of the connecting plate is provided with a screw rod, which passes through another part of the protrusion. A nut is threaded onto the screw rod, and in use, the nut abuts against the bottom surface of the protrusion.

[0010] Furthermore, a movable plate is provided on the other side of the baffle. The movable plate is sleeved on the guide rod, which is installed on the lifting frame. The movable plates on both sides of the lifting frame correspond one-to-one and are connected to a hinge shaft. A connecting rod is sleeved on the hinge shaft. One end of the connecting rod is rotatably connected to a gear ring. The gear ring is rotatably installed on the inside of the lifting frame and meshes with the drive gear. The drive gear is installed on the transmission shaft, which is rotatably installed on the lifting frame.

[0011] Furthermore, the clamping block located below passes through the baffle, and a top plate is provided at one end facing the center of the lifting frame. The top plate is sleeved on the end rod, one end of the end rod is installed on the baffle, and the other end is provided with a retaining ring. A second spring is sleeved on the end rod, and the two ends of the second spring abut against the top plate and the retaining ring respectively, and are always in a compressed state.

[0012] Furthermore, the bottom surface of the clamping block located below is an inclined surface, and the end of the inclined surface away from the center of the lifting frame faces upward.

[0013] Furthermore, the lifting frame is sleeved on the support rod and connected to the moving end of the vertical lifting mechanism. Both the vertical lifting mechanism and the support rod are installed on the horizontal plate.

[0014] The advantages of this invention are as follows: the clamping assembly clamps the end of the oil pipe, preventing the end of the oil pipe from falling directly onto the conveying track after sawing, thus facilitating the transfer of the oil pipe end; and the method of simultaneously sawing the two oil pipes facing each other ensures sawing efficiency while reducing the range of position adjustment of the sawing equipment, making the operation more convenient; when the pressure block rises, the lifting frame automatically rises, ensuring that the lifting frame is coaxial with the oil pipe, facilitating the clamping of the oil pipe end.

[0021] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0022] like Figures 1-5 As shown, this example provides a tooling for tubing end cutting, including: a conveying track 100, a positioning component 200, and a clamping component 300.

[0023] There are two conveying tracks 100, arranged sequentially along their conveying direction, for conveying oil pipes; there are two positioning components 200, each located above the conveying track 100, including two support plates 201 respectively located on both sides of the conveying track 100 and movable in the vertical direction. Multiple pressure blocks 202 are provided above the support plates 201 along their length direction to limit the oil pipes and prevent them from shifting during the sawing process; the clamping component 300 includes a lifting frame 301 located between the conveying tracks 100 and movable in the vertical direction. Multiple baffles 302 are arranged at intervals on both sides of the lifting frame 301 along its circumference and move synchronously in its radial direction. A clamping block 303 is provided on the side of the baffle 302 away from the center of the lifting frame 301, and the lower clamping block 303 is movable along the thickness direction of the lifting frame 301, so that the opposing ends of the two oil pipes can be clamped at the same time, so that the opposing ends of the two oil pipes can be sawed at the same time.

[0024] Specifically, the lifting frame 301 has two horizontal plates 304 on both sides. The horizontal plates 304 have multiple protrusions 305 along their length. Some of the protrusions 305 have through rods 306 on their bottom surfaces. The through rods 306 pass through the support plate 201. Before the oil pipe is delivered to the positioning component 200, the protrusions 305 abut against the top surface of the support plate 201 to provide support for the horizontal plates 304. The lifting frame 301 is in the initial position of its stroke.

[0025] Specifically, the side of the pressure block 202 facing the conveying starting end of the conveying track 100 is a downward slope, and both ends are provided with connecting plates 203. The connecting plates 203 are sleeved on the vertical rod 204, which is mounted on the support plate 201. A retaining ring 205 is provided at the upper end of the vertical rod 204, and a first spring 206 is sleeved on the vertical rod 204. The two ends of the first spring 206 abut against the connecting plate 203 and the retaining ring 205 respectively, and are always in a compressed state. Under the action of the first spring 206, the pressure block 202 is compressed. The pressure block 202 always tends to move downwards. When the oil pipe is transported through the conveying track, one end of the oil pipe abuts against the inclined surface of the pressure block 202, forcing the pressure block 202 to move upwards. The first spring 206 is further compressed. After the pressure block 202 moves upwards for a certain distance, the lifting frame 301 also moves upwards until the side of the oil pipe contacts the bottom surface of the pressure block 202. In order to ensure the limiting effect of the pressure block 202 on the oil pipe, the bottom surface of the pressure block 202 can be set into a V shape.

[0026] Specifically, the bottom surface of the connecting plate 203 is provided with a screw 207, which passes through another part of the protrusion 305. A nut is threaded onto the screw 207. After the pressure block 202 moves upward a certain distance, and this distance is half of its total upward stroke, the nut abuts against the bottom surface of the protrusion 305 and drives the horizontal plate 304 to move upward synchronously. This allows the axis of the lifting frame 301 to be coaxial with the axis of the oil pipe, which facilitates clamping the end of the oil pipe. For oil pipes of different diameters, the upward movement distance of the pressure block 202 is also different. The upward distance of the lifting frame 301 can be adjusted by rotating the nut to accommodate oil pipes of different diameters.

[0027] Specifically, a movable plate 307 is provided on the other side of the baffle 302. The movable plate 307 is sleeved on the guide rod 308, which is installed on the lifting frame 301. The movable plates 307 on both sides of the lifting frame 301 correspond one-to-one and are connected to a hinge shaft 309. A connecting rod 310 is sleeved on the hinge shaft 309. One end of the connecting rod 310 is rotatably connected to a gear ring 311. The gear ring 311 is rotatably installed inside the lifting frame 301 and interacts with the drive gear 312. The drive gear 312 is mounted on the transmission shaft 313, which is rotatably mounted on the lifting frame 301. When clamping the end of the oil pipe, the transmission shaft 313 can be driven to rotate by a power device, such as a motor. The transmission shaft 313 drives the drive gear 312 to rotate, which in turn drives the gear ring 311 to rotate. Under the pull of the connecting rod 310, the clamping blocks 303 on both sides of the lifting frame 301 will move synchronously towards each other, thereby clamping the end of the oil pipe.

[0028] Specifically, the lifting frame 301 is sleeved on the support rod 318 and connected to the moving end of the vertical lifting mechanism. Both the vertical lifting mechanism and the support rod 318 are installed on the horizontal plate 304. After the sawing is completed, the lifting frame 301 is moved upward by the vertical lifting mechanism to remove the oil pipe end from the conveying track 100. Then the oil pipe end can be removed. At the same time, the conveying track 100 continues to convey the oil pipe, moving the oil pipe from one conveying track 100 to another. Then the lifting frame 301 is moved downward to the lowest point of its stroke.

[0029] Specifically, to avoid interference between the lifting frame 301 and the oil pipe during its downward movement, a clamping block 303 located at the bottom is inserted into the baffle 302, and a top plate 314 is provided at one end facing the center of the lifting frame 301. The top plate 314 is sleeved on the end rod 315, one end of which is installed on the baffle 302, and the other end is provided with a retaining ring 316. A second spring 317 is sleeved on the end rod 315, with both ends of the second spring 317 abutting against the top plate 314 and the retaining ring 316 respectively, and always in a compressed state. The bottom surface of the clamping block 303 located at the bottom is inclined, and the end of the inclined surface away from the center of the lifting frame 301 faces upward. During the downward movement of the lifting frame 301, the inclined surface of the clamping block 303 will contact the end edge of the oil pipe, forcing the clamping block 303 to move. The second spring 317 is further compressed until the bottom clamping block 303 has completely passed through the oil pipe, and the clamping block 303 will return to its original position under the action of the second spring 317.

[0030] Since the above are merely preferred embodiments of this utility model and are not intended to limit this utility model, it is obvious that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
