Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing technology, and in particular to an air-cooled coated steel pipe cutting device. Background Technology

[0002] During the production process, steel pipes undergo anti-corrosion treatment, after which their surface is covered with an anti-corrosion coating. In this process, adjacent steel pipes are placed very close together, and the anti-corrosion coating covers the seam between them. Therefore, after the anti-corrosion treatment, the adjacent steel pipes need to be separated at the seam. Simultaneously, a certain length of the anti-corrosion coating at the pipe ends needs to be cut to facilitate the subsequent peeling of this portion of the coating.

[0003] The existing Chinese utility model patent application number 201810896803.8, entitled "A Wind-Cooled Steel Pipe Cutting Device," discloses that "by setting air hoses at both ends of the steel pipe, cold air can be blown out from the cutting opening to cool the blade, and the rotating cylinder is set to concentrate the cold air to cool the blade." After the steel pipe is cut, the hoses need to be removed from both ends of the steel pipe, and the fixing sleeves need to be loosened to remove the steel pipe. When cutting the next set of steel pipes, the hoses need to be connected to the new steel pipes and fixed again, which is cumbersome and has low cutting efficiency. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figure 1-5This utility model provides a technical solution: an air-cooled coated steel pipe cutting device, including a frame 1, a support 2 fixedly connected to the frame 1, a cutting machine 5 mounted on the support 2, and further including:

[0034] like Figure 4 The feeding assembly 9 shown includes a belt 91, a stepper motor 92, a drive roller 93, and a driven roller 94. The drive roller 93 and driven roller 94 are rotatably mounted at both ends of the mounting groove 101. The belt 91 is driven by the drive roller 93 and driven roller 94. The stepper motor 92 is fixedly mounted on the frame 1, and its output shaft is driven by the drive roller 93. When the stepper motor 92 is started, it drives the drive roller 93 to rotate. With the transmission cooperation of the belt 91 and driven roller 94, the belt 91 drives the support base 81 to move, conveying the steel pipes placed on the support base 91 and improving the efficiency of steel pipe loading and unloading.

[0035] like Figure 4 The support assembly 8 shown includes a support base 81, a connecting block 82, and rollers 83. Multiple sets of support bases 81 are equidistantly arranged along the transmission direction of the belt 91. The support bases 81 and the belt 91 are fixedly connected by the connecting blocks 82. A trapezoidal through-slot is formed on the support base 81, with the trapezoidal inclined surfaces on both sides of the through-slot tangent to the surface of the steel pipe. Rollers 83 are rotatably mounted on both sides of the bottom of the support base 81, and the rollers 83 roll in contact with the track grooves 102 on both sides of the frame 1 of the mounting groove 101. The contact between the rollers 83 and the track grooves 102 allows the support base 81 and the frame 1 to support the steel pipe, preventing the belt 91 from being overloaded and affecting its transmission.

[0036] like Figure 1 As shown, the first hydraulic telescopic rod 4 is fixedly installed on the bracket 2, and the telescopic rod end of the first hydraulic telescopic rod 4 is fixedly connected to the cutting machine 5. After the steel pipe is fixed, the cutting machine 5 is started first, and then the first hydraulic telescopic rod 4 is started to drive the cutting machine 5 to descend. The cutter rotates at high speed to cut the coating at the seam of the front and rear steel pipes, separating the front and rear steel pipes.

[0037] like Figure 1 The pressing assembly shown has two sets, arranged on both sides of the cutting machine 5. Each pressing assembly includes a second hydraulic telescopic rod 6 and an arc-shaped pressure plate 7. The second hydraulic telescopic rod 6 is fixedly mounted on the bracket 2, and its telescopic end is fixedly connected to the arc-shaped pressure plate 7 to clamp and position the support pipe. When the seam of the front and rear steel pipes moves to the cutting blade, the belt 91 stops driving. Then, the second telescopic rod 6 is driven to press down the pressure plate 7, positioning the front and rear steel pipes and preventing uneven cutting surfaces caused by the steel pipes sliding during the cutting of the coating seam.

[0038] like Figure 2 and Figure 3The air-cooling assembly 3 shown has two sets, symmetrically arranged on both sides of the bracket 2. The air-cooling assembly 3 includes an exhaust fan 31 and a cold air duct 32. The exhaust fan 31 is fixed to the outside of the bracket 2. Coolant chambers 201, which accommodate the cold air ducts 32, are opened on both sides of the bracket 2. The coolant chambers 201 contain coolant that covers the cold air ducts 32. The exhaust end of the exhaust fan 31 is connected to the inlet end of the cold air duct 32, and the exhaust end of the cold air duct 32 faces the cutting part of the cutting machine 5 and the steel pipe. Air is drawn into the cold air duct 32 by the exhaust fan 31, cooled by the coolant chambers 201, and then blown out by the cold air duct 32. The cold air continuously cools the cutting machine 5 and the cutting blade at the pipe seam cutting point. The cooling process is separated from the cutting, steel pipe fixing, and steel pipe unloading processes, making operation simple and cutting efficiency high.

[0039] Working principle: In use, first, the steel pipe is placed on the support base 81. Then, the stepper motor 92 is started to drive the drive roller 93 to rotate. Under the transmission cooperation of the belt 91 and the driven roller 94, the belt 91 drives the support base 81 to move, conveying the steel pipe placed on the support base 91 until the seam of the front and rear steel pipes moves to the cutter. When this happens, the belt 91 stops. Then, the second telescopic rod 6 is driven to drive the pressure plate 7 to press down, positioning the front and rear steel pipes and preventing the steel pipes from sliding and causing uneven cut surfaces when cutting the coating of the pipe seam. After the steel pipe is fixed, the cutting machine 5 is started first, and then the first hydraulic telescopic rod 4 is started to drive the cutting machine 5 to descend. The cutter rotates at high speed to cut the coating at the pipe seam of the front and rear steel pipes and separate the front and rear steel pipes. At the same time as cutting, the exhaust fan 31 draws air into the cold air pipe 32. The air is cooled by the coolant chamber 201 and the cold air pipe 32 blows out cold air. The cold air continuously cools the cutting machine 5 and the cutter at the pipe seam cutting point. The cooling work is carried out separately from the cutting work, the steel pipe fixing work and the steel pipe unloading work. The operation is simple and the cutting efficiency is high.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
