Description

Technical Field

[0001] This utility model relates to the technical field of drill pipe processing equipment, and in particular to a drill pipe thickening machine with automatic cooling and lubrication function. Background Technology

[0002] A drill pipe thickening machine is a specialized piece of equipment used to strengthen the ends of oil drill pipes, geological drill pipes, and other tubular materials. It increases the strength of the pipe ends by increasing their wall thickness, ensuring the reliability of subsequent threading or welding. Its core function is to address the issue of wall thinning at the pipe ends caused by processing without significantly increasing the overall weight of the drill pipe. It performs localized thickening treatment on the drill pipe ends to enhance their compressive, torsional, and fatigue strength, meeting the demands of high-intensity drilling operations. During operation, the drill pipe thickening machine requires steps such as mold cooling and lubrication. These steps aim to improve processing efficiency, protect equipment, and optimize product quality, including mold lubrication and wear protection, temperature control and thermal protection, and improved product surface quality.

[0003] In existing technologies, during the production process of drill pipe thickening machines, steps such as cooling, purging, and lubrication are all performed manually by workers. However, this method has many drawbacks, including uneven lubrication spraying, high consumption of graphite lubricant, and consequently, poor stability of the thickening process. Furthermore, manual operation incurs significant labor costs, is physically demanding, and is not environmentally friendly. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a drill pipe thickening machine with automatic cooling and lubrication functions.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A drill pipe thickening machine with automatic cooling and lubrication function includes a machine body and a mold disposed in the machine body. The machine body is characterized by further including a cooling and lubrication module and a moving module connected to each other. The cooling and lubrication module includes a cooling water nozzle, a gas nozzle, and a graphite nozzle, capable of spraying water, air, and graphite into the mold, respectively. The moving module includes an X-axis support, a Y-axis support, a Z-axis support, and a sliding support. The cooling water nozzle, gas nozzle, and graphite nozzle are fixedly connected to the sliding support via connecting rods. The sliding support is slidably connected to the Z-axis support, the Z-axis support is slidably connected to the Y-axis support, and the Y-axis support is slidably connected to the X-axis support.

[0010] Furthermore, a cylinder is provided on the Y-axis bracket, and the push rod at the front end of the cylinder is fixedly connected to the Z-axis bracket.

[0011] Furthermore, a third slider is provided on the Z-axis bracket, and a third guide rail is provided on the sliding bracket. Through the sliding cooperation between the third slider and the third guide rail, the sliding bracket can slide along the Z-axis bracket.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0025] To enhance understanding of this utility model, we will now describe it in further detail with reference to the accompanying drawings. This embodiment is only used to explain this utility model and does not constitute a limitation on the scope of protection of this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," "fixing," and "setting," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] like Figure 1-5 As shown, a specific embodiment of a drill pipe thickening machine with automatic cooling and lubrication function includes a machine body 1, a mold disposed in the machine body 1, a cooling and lubrication module 2 and a moving module 3 connected to each other. The cooling and lubrication module 2 includes a cooling water nozzle 201, a gas nozzle 202, and a graphite nozzle 203, which can spray water, air, and graphite into the mold, respectively. The moving module 3 includes an X-axis support 4, a Y-axis support 5, a Z-axis support 6, and a sliding support 7. The cooling water nozzle 201, gas nozzle 202, and graphite nozzle 203 are fixedly connected to the sliding support 7 through a connecting rod 24. The sliding support 7 is slidably connected to the Z-axis support 6, the Z-axis support 6 is slidably connected to the Y-axis support 5, the Y-axis support 5 is slidably connected to the X-axis support 4, and the X-axis support 4 is fixedly connected to the machine body 1. The moving module 3 can drive the cooling water nozzle 201, gas nozzle 202, and graphite nozzle 203 to move in any direction within the mold. The mold includes an upper mold 22 and a lower mold 23. The lower mold 23 is fixedly connected to the machine body 1, and the upper mold 22 is movably connected to the machine body 1.

[0030] like Figure 2As shown, cooling water nozzles 201, gas nozzles 202, and graphite nozzles 203 are connected to the front end of the connecting rod 24 and can extend into the mold as the connecting rod 24 moves. There are three cooling water nozzles 201, each with a flat front end to increase the spraying area and improve the mold's cooling efficiency. There are two graphite nozzles 203, with openings facing upwards and downwards respectively, allowing for uniform spraying of graphite onto the inner surface of the mold. Under high temperature and pressure, graphite forms a lubricating film, reducing direct contact between the mold and the workpiece, significantly reducing frictional resistance, and preventing scratches or adhesion of metal materials to the mold surface. Uniform graphite spraying reduces mold wear caused by high-temperature oxidation and mechanical wear, especially suitable for thickened pipe ends subjected to repeated impacts, increasing lifespan by more than 30%. Graphite's high thermal conductivity quickly transfers frictional heat, preventing localized overheating and deformation of the mold, and maintaining stable processing temperatures.

[0031] like Figure 3 , 4 As shown, a first guide rail 8 is provided on the X-axis support 4, and a first slider 9 is provided on the Y-axis support 5. Through the sliding engagement of the first slider 9 and the first guide rail 8, the Y-axis support 5 can slide along the X-axis support 4. A first rack 10 is provided on the X-axis support 4, and a first motor 11 is connected to the Y-axis support 5. A first gear 12 is connected to the drive shaft of the first motor 11, and the first gear 12 meshes with the first rack 10. When the first motor 11 drives the first gear 12 to rotate, the first gear 12 moves along the first rack 10, thereby driving the Y-axis support 5 to move horizontally along the X-axis support 4, realizing the movement of the cooling and lubrication module 2 in the X-axis direction.

[0032] like Figure 3 As shown, a second guide rail 13 is provided on the Y-axis support 5, and a second slider 14 is provided on the Z-axis support 6. Through the sliding engagement of the second slider 14 and the second guide rail 13, the Z-axis support 6 can slide along the Y-axis support 5. A cylinder 15 is provided on the Y-axis support 5, and the push rod 16 at the front end of the cylinder 15 is fixedly connected to the Z-axis support 6. When the cylinder 15 operates, the push rod 16 at the front end extends and retracts, which can push the Z-axis support 6 to move horizontally along the Y-axis support 5, realizing the movement of the cooling and lubrication module 2 in the Y-axis direction.

[0033] like Figure 5As shown, a third slider 17 is provided on the Z-axis support 6, and a third guide rail 18 is provided on the sliding support 7. Through the sliding engagement of the third slider 17 and the third guide rail 18, the sliding support 7 can slide along the Z-axis support 6. A second motor 19 is provided on the Z-axis support 6, and a second rack 20 is connected to the sliding support 7. A second gear 21 is connected to the drive shaft of the second motor 19, and the second gear 21 meshes with the second rack 20. When the second motor 19 drives the second gear 21 to rotate, the second gear 21 moves along the second rack 20, thereby driving the sliding support 7 to move vertically up and down along the Z-axis support 6, realizing the movement of the cooling and lubrication module 2 in the Z-axis direction.

[0034] Preferably, the operation of the first motor 11, the second motor 19, the cylinder 15, and the cooling and lubrication module 2 is controlled by a PLC connection. This allows the cooling and lubrication module 2 to move freely and extend into any position within the mold cavity. First, water is sprayed into the mold cavity for cooling. During water spraying, the cooling water nozzle 201 can move back and forth. After cooling, the gas nozzle 202 performs a water blowing step. Finally, graphite is sprayed onto the mold using the graphite nozzle 203. The graphite atomizes the graphite when sprayed from the graphite nozzle 203, increasing the spraying area. This cooling and spraying process ensures uniformity, significantly reduces the consumption of graphite lubricant, promotes the stability of the thickening process of the thickening machine, and saves labor costs.

[0035] The above specific embodiments are only for illustrating the technical concept and structural features of this utility model, and are intended to enable those skilled in the art to implement them. However, the above content does not limit the protection scope of this utility model. Any equivalent changes or modifications made in accordance with the spirit and essence of this utility model shall fall within the protection scope of this utility model.
