Description

Technical Field

[0001] This utility model relates to the field of drill pipe processing technology, and in particular to an automatic cutting line for drill pipe bodies. Background Art

[0002] Mining drill pipes are welded together from three parts: a male connector, a female connector, and the drill pipe body. After the raw materials for the drill pipe body arrive at the factory, they first need to undergo a sawing process. To ensure the quality of the subsequent drill pipe forming, each raw material must be trimmed at both ends. While ensuring that each pipe leaving the factory meets the length requirements, the sawn surface must be smooth and the pipe body clean and tidy. Currently, most technologies use sawing machines to cut the raw materials. During this process, loading, unloading, moving, and determining the sawing dimensions all require operator assistance, resulting in high labor intensity and low cutting efficiency, accuracy, and safety. Therefore, improvements are needed. Utility Model Content

[0003] The purpose of this invention is to provide an automatic cutting line for drill pipe bodies to solve the problems of low cutting efficiency, accuracy, and safety in the existing drill pipe body processing.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] An automatic cutting line for drill pipe bodies, comprising:

[0006] main body of the saw;

[0007] The pushing mechanism is used to drive the tube material to feed axially. It includes several drive rollers located on the feeding side and the discharge side of the saw body. The drive rollers are arranged in a row at intervals and the arrangement direction is perpendicular to the cutting direction of the saw body.

[0008] The raw material rack, located on the feed side of the main body of the saw, is used to feed the pipe material to be cut to the pushing mechanism;

[0009] The discharge rack, located on the discharge side of the main body of the saw, is used to receive the cut pipe material;

[0010] The material stop mechanism, located on the discharge side of the main body of the saw, is used to determine the size of the tube after cutting;

[0011] The material turning mechanism is used to transfer tubular material from the raw material rack to the pushing mechanism, and to transfer tubular material from the pushing mechanism to the discharge rack.

[0012] Optionally, the material blocking mechanism includes a material blocking frame and a baffle plate disposed on the material blocking frame. The baffle plate limits the end of the tube material. A contact switch is disposed on the baffle plate. The contact switch is signal-connected to the material pushing mechanism. When the end of the tube material triggers the contact switch, the drive roller of the material pushing mechanism stops rotating. The distance from the baffle plate to the main body of the saw is adjustable.

[0013] Optionally, the raw material rack is located on one side of the pushing mechanism, and the stacking platform of the raw material rack is inclined towards the pushing mechanism, so that the pipe material rolls freely towards the pushing mechanism under the action of gravity, and a stop is provided at the end of the raw material rack near the pushing mechanism.

[0014] Optionally, the turning mechanism includes a turning plate located on one side of each drive roller. The turning plate is provided with an actuating part. By changing the rotation angle of the turning plate, the actuating part can be made higher or lower than the top surface of the stop and the conveying plane of the drive roller.

[0015] When the actuating part is higher than the top surface of the stop, the actuating part lifts up one of the tubes that is against the stop and guides the tube over the stop and rolls it onto the drive roller.

[0016] When the actuating part is higher than the conveying plane of the drive roller, the actuating part lifts the tube on the drive roller and guides the tube to roll down onto the discharge rack.

[0017] When the actuating part is lower than the top surface of the stop block and the conveying plane of the drive roller, the actuating part does not contact the tube material.

[0018] Optionally, adjacent flip plates are connected by a linkage, so that all flip plates move synchronously.

[0019] Optionally, the discharge rack is located on one side of the pushing mechanism, and a storage trough is provided at the end of the discharge rack away from the pushing mechanism. The receiving platform of the discharge rack is inclined to the storage trough, so that the tube material rolls freely into the storage trough under the action of gravity.

[0020] Optionally, it also includes a scrap rack, which is located on the other side of the pushing mechanism opposite to the raw material rack. The scrap rack is used to receive the leftover material after the raw material is cut.

[0021] Optionally, each drive roller is driven by a separate motor, and a passive roller is provided between two adjacent drive rollers.

[0022] Optionally, it also includes a water-cooling device, which includes several support frames disposed in the gaps of the discharge rack. Each support frame is driven to lift and lower by a separate cylinder to lift the tube material away from the receiving platform of the discharge rack.

[0023] Optionally, the purging device also includes an air blowing mechanism located above the receiving platform of the discharge rack, which blows compressed air to the port of the raised tube to purge the inner wall of the tube.

[0024] In summary, compared with existing technologies, this automatic drill pipe cutting line automates a series of actions, including feeding, pushing, determining dimensions, sawing, and unloading of the pipe material, greatly improving the efficiency and quality of pipe cutting, while reducing manual labor intensity and increasing production safety.

[0038] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0039] Please see Figures 1 to 3 As shown, this preferred embodiment provides an automatic cutting line for drill pipe bodies, including a sawing machine body 1, a pushing mechanism 2, a raw material rack 3, a discharge rack 4, a blocking mechanism 5, and a flipping mechanism 6, wherein:

[0040] The main body 1 of the saw is an existing sawing equipment used for cutting pipes;

[0041] The pushing mechanism 2 is used to drive the tube material to feed axially. It includes several driving rollers 21 located on the feeding side and the discharging side of the saw body 1. Each driving roller 21 is arranged in a row at intervals, and the arrangement direction is perpendicular to the cutting direction of the saw body 1.

[0042] The raw material rack 3 is located on the feeding side of the main body 1 of the saw and is used to feed the pipe material to be cut to the pushing mechanism 2;

[0043] The discharge rack 4 is located on the discharge side of the main body 1 of the saw and is used to receive the cut pipe material;

[0044] The material blocking mechanism 5 is located on the discharge side of the saw body 1 and is used to determine the size of the tube after cutting;

[0045] The material turning mechanism 6 is used to transfer the pipe material from the raw material rack 3 to the pushing mechanism 2, and to transfer the pipe material from the pushing mechanism 2 to the discharge rack 4.

[0046] Therefore, the automatic cutting line for drill pipes has achieved automated completion of a series of actions such as feeding, pushing, determining dimensions, sawing, and unloading of pipe materials, which greatly improves the efficiency and quality of pipe cutting, while reducing the intensity of manual labor and ensuring high production safety.

[0047] As an optional solution, the material blocking mechanism 5 includes a material blocking frame 51 and a baffle 52 disposed on the material blocking frame 51. The baffle 52 limits the end of the tube material. A contact switch is disposed on the baffle 52. The contact switch is signal-connected to the material pushing mechanism 2. When the end of the tube material triggers the contact switch, the drive roller 21 of the material pushing mechanism 2 stops rotating, thereby quickly determining the cutting size.

[0048] Furthermore, the distance between the baffle 52 and the main body 1 of the saw is adjustable. On the one hand, the position of the baffle 52 can be adjusted according to the target forming size. On the other hand, the baffle 52 is controlled to stay away from the tube material during sawing to avoid affecting the sawing accuracy. The baffle 52 can also prevent the cut tube material from being further fed.

[0049] In addition, considering that the pipe material has a certain inertia during the movement process, it is necessary to ensure that the baffle 52 has sufficient stopping ability and ensure positional accuracy. Preferably, the baffle frame 51 is equipped with a displacement sensor to monitor the relative position of the baffle 52.

[0050] As an alternative, the raw material rack 3 is located on one side of the pushing mechanism 2, and the stacking platform of the raw material rack 3 is inclined to the pushing mechanism 2, so that the pipes roll freely towards the pushing mechanism 2 under the action of gravity. A stop block 31 is provided at the end of the raw material rack 3 closest to the pushing mechanism 2. Multiple raw material pipes are neatly arranged on the raw material rack 3, and the lowest pipe is limited by the stop block 31, so that the pipes are conveyed to the pushing mechanism 2 one by one by gravity.

[0051] As an optional solution, the turning mechanism 6 includes a turning plate 61 located on one side of each drive roller 21. The turning plate 61 is provided with an action part. By changing the rotation angle of the turning plate 61, the action part is made to be higher or lower than the top surface of the stop block 31 and the conveying plane of the drive roller 21. When the action part is higher than the top surface of the stop block 31, the action part lifts a tube material that is against the stop block 31 and guides the tube material to roll over the stop block 31 and onto the drive roller 21. When the action part is higher than the conveying plane of the drive roller 21, the action part lifts the tube material on the drive roller 21 and guides the tube material to roll onto the discharge rack 4. When the action part is lower than the top surface of the stop block 31 and the conveying plane of the drive roller 21, the action part does not contact the tube material.

[0052] The infeed-side tilting plate 61 and the discharge-side tilting plate 61 serve different functions for the tube material. In this embodiment, tilting plates 61 of the same shape are used, thus designing a two-section working part, such as... Figure 3 As shown, the two functional sections are stepped and do not interfere with each other.

[0053] As an alternative, adjacent flipping plates 61 are connected by a connecting rod 62, so that all flipping plates 61 move synchronously and ensure that the flipping angle is consistent at all parts of the pipe.

[0054] As an alternative, the discharge rack 4 is located on one side of the pushing mechanism 2. The end of the discharge rack 4 away from the pushing mechanism 2 is provided with a storage trough 41, and the receiving platform of the discharge rack 4 is inclined to the storage trough 41, so that the tube material rolls freely into the storage trough 41 under the action of gravity, and thus is discharged freely by gravity.

[0055] As an optional solution, the automatic cutting line for the drill pipe also includes a scrap rack 7. The scrap rack 7 is located on the other side of the pushing mechanism 2, opposite to the raw material rack 3. The scrap rack 7 is used to receive the remaining material after the pipe is cut. The feeding method at the scrap rack 7 is the same as that at the discharge rack 4, which will not be described in detail here.

[0056] As an alternative, each drive roller 21 is driven by a separate motor 22 to regulate the feed speed of the tube; a passive roller 23 is provided between two adjacent drive rollers 21 to fill the gap between the two drive rollers 21 to accommodate small-sized tubes.

[0057] As an optional solution, the automatic drill pipe cutting line also includes a cooling device 8. The cooling device 8 includes several support frames 81 disposed in the gaps of the discharge rack 4. Each support frame 81 is driven to rise and fall by an individual cylinder 82 to lift the pipe material away from the receiving platform of the discharge rack 4. The discharge rack 4 is equipped with a tilting stop block 42, which is used to position the pipe material so that the support frames 81 can accurately lift the pipe material. Since coolant is used when sawing the pipe material, the cooling device 8 is used to ensure that the pipe material is dry before it is placed into the storage tank 41.

[0058] Furthermore, the water-cooling device 8 also includes an air-blowing mechanism 83 located above the receiving platform of the discharge rack 4. The air-blowing mechanism 83 is used to blow compressed air onto the port of the raised tube to sweep the inner wall of the tube and effectively remove the moisture from the inner wall of the tube.

[0059] It should be noted that the above-mentioned optional implementation methods can be combined in any way, and the resulting implementation methods are all within the protection scope of this utility model.

[0060] The specific working process of the automatic cutting line of the drill pipe body is as follows:

[0061] (1) The pipe material to be cut is placed on the raw material rack 3 and waits to be put on the line;

[0062] (2) The material turning mechanism 6 transfers the tubes on the raw material rack 3 one by one to the material pushing mechanism 2;

[0063] (3) The pushing mechanism 2 pushes the tube material axially through the saw body 1 until the end of the tube material contacts the baffle 52 of the blocking mechanism 5 to determine the cutting and forming size;

[0064] (4) The main body of the sawing machine 1 saws the pipe material;

[0065] (5) The material turning mechanism 6 transfers the cut pipe material to the discharge rack 4;

[0066] (6) The water-cooling device 8 dries the pipe material;

[0067] (7) The processed pipe material finally rolls down along the discharge rack 4 into the storage tank 41;

[0068] (8) The pushing mechanism 2 pushes the remaining material after the tube is cut to continue to move forward and cut again; or, the flipping mechanism 6 transfers the insufficient material to the scrap rack 7, and the pushing mechanism 2 pushes another tube to be cut.

[0069] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
