[0002] Steel pipe processing is a process involving multiple steps and technologies, which aims to transform raw steel pipes into finished steel pipes that meet specific specifications and requirements. Rough machining of steel pipes is the process of preliminary processing of steel pipes. The main purpose is to remove burrs, scales, dirt, etc. on the surface of the steel pipes, and at the same time perform preliminary processing on their appearance to meet the needs of subsequent processing or use. CNC blades (such as adapter blades TNMG1604 and other models) are used to perform high-precision processing on steel pipes to achieve automation and mass production. Excess material on the surface of the steel pipes is removed and the shape is corrected by cutting, milling, etc. Steel pipe finishing is On the basis of rough processing, the steel pipe is processed more delicately to meet the higher requirements of steel pipe size, shape, surface quality, etc. in specific application fields. The shearing method is suitable for processing small thin-walled pipes. The required shape is obtained by multiple shearing, flipping and re-shearing. In the process of steel pipe finishing, a strict quality control system should be established to ensure that each processing link meets the quality requirements.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-6 The utility model provides a technical solution: a double-head turning tool for steel pipe processing that is convenient for rough and fine processing, including: a workbench 1, a first motor 2, a screw rod 3, a moving block 4, a second motor 5, a connecting shaft 6, a clamping assembly 7, an operating rod 8, a gear 9, a toothed plate 10, a rectangular table 11, a second arc plate 12, a connecting rod 13, a spring 14, a first arc plate 15, a limiting rod 16, a tool assembly 17, a slag discharge port 18 and a collection box 19;

[0030] When using this double-ended turning tool for steel pipe machining that is convenient for rough and fine machining, Figure 1 and Figure 2 As shown, two TNMG1604 CNC blades are fixedly arranged on the upper side of the tool assembly 17, and the two CNC blades have a drop position of 0.2 in the horizontal direction. During the cutting process, one blade can be used for multiple purposes, and rough and fine processing are performed together, which can save tool change time and improve efficiency. The blade that contacts the steel pipe first will perform rough processing on the steel pipe. After rough processing, the surface of the steel pipe is smooth. As the steel pipe rotates and moves, the other blade will perform fine processing on the steel pipe, and the unprocessed steel pipe will be made into the required steel pipe;

[0031] like Figure 1 , Figure 3 and Figure 4 As shown, a clamping assembly 7 is provided on the upper side of the workbench 1, and a conveying roller is rotatably connected to the upper side of the workbench 1. The steel pipe to be processed is sleeved on the outer side of the clamping assembly 7, and the handle on the side of the operating rod 8 is rotated to allow the operating rod 8 to rotate in the clamping assembly 7. Since the operating rod 8 is rotatably connected to the clamping assembly 7, the rotation of the operating rod 8 will rotate with the gear 9, and because the gear 9 is meshed and connected with the toothed plate 10, the rotating gear 9 will cause the toothed plate 10 to move left and right. When the toothed plate 10 moves to the right, the toothed plate 10 will move the rectangular platform 11 to the right. In addition, a limiting rod 16 is also provided on the right side of the rectangular platform 11. The limiting rod 16 is slidably connected to the clamping assembly 7. The limiting rod 16 moves with the movement of the rectangular platform 11, and the limiting rod 16 has a limiting effect on the rectangular platform 11 to prevent the rectangular platform 11 from deviating, thereby causing the first arc plate 15 on the clamping assembly 7 to be unable to move outward synchronously.

[0032] like Figure 4 , Figure 5 and Figure 6As shown, the rectangular platform 11 fits tightly with the inner side of the second curved plate 12. When the rectangular platform 11 moves to the right, the second curved plate 12 will be squeezed by the rectangular platform 11 set in a truncated cone shape, so that the second curved plate 12 moves outward. When the second curved plate 12 moves outward, the connecting rod 13 will also move outward. At this time, the spring 14 on the outside of the connecting rod 13 will be elastically deformed, and the first curved plate 15 will also move outward. When the first curved plate 15 fits tightly with the inner wall of the steel pipe, the remaining first curved plates 15 also fit tightly with the inner wall of the steel pipe. When the operating rod 8 cannot rotate, the first curved plate 15 fits tightly with the inner wall of the steel pipe, and the clamping assembly 7 is coaxial with the steel pipe, which is convenient for rough and fine processing of the steel pipe.

[0033] like Figure 1 As shown, a first motor 2 is arranged inside the workbench 1, and the output shaft of the first motor 2 is fixedly connected to the screw rod 3, and the right side of the screw rod 3 is rotatably connected to the workbench 1. When the first motor 2 is started, the first motor 2 will rotate with the screw rod 3. Since the screw rod 3 is threadedly connected to the moving block 4, and the moving block 4 is engaged with the workbench 1, the rotation of the screw rod 3 will cause the moving block 4 to move left and right inside the workbench 1, thereby facilitating the left and right movement of the steel pipe on the upper side of the workbench 1.

[0034] like Figure 1 , Figure 3 and Figure 4 As shown, after the steel pipe is clamped, the second motor 5 is started, and the second motor 5 will rotate with the connecting shaft 6, and then rotate with the clamping assembly 7, so that the steel pipe is rotated rightward on the upper side of the workbench 1, and the rotating steel pipe will be synchronously rough-finished by the two blades on the tool assembly 17. The processed steel pipe will be cleaned of debris, which will enter the collection box 19 from the slag discharge port 18. The slag discharge port 18 is symmetrical about the vertical center axis of the workbench 1, which is convenient for collecting the debris. The device saves tool change time and reduces the path of repeated processing, thereby greatly saving time and accelerating processing efficiency.

[0035] like Figure 4 , Figure 5 and Figure 6 As shown, when the processing is completed, the operating rod 8 is rotated, and the spring 14 will also restore its elastic deformation, allowing the connecting rod 13 to move inward, thereby moving the first arc plate 15 inward, disconnecting the first arc plate 15 from the inner wall of the steel pipe, and then removing the steel pipe.

[0036] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in the field. The standard parts used in the utility model can be purchased from the market, and special-shaped parts can be customized according to the records in the specification and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the prior art. The machinery, parts and equipment all adopt the conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be described in detail here.
