Description

Technical Field

[0001] The present application relates to the field of oil casing processing, and in particular to a coolant water channel converter for oil casing processing. Background Art

[0002] Since the 21st century, most of my country's conventional oil and gas fields have entered the middle and late stages of exploitation, and oil production rates have dropped significantly. In order to increase domestic oil and natural gas production, it has become a general trend to gradually shift from the exploitation of conventional oil and gas resources to the exploitation of unconventional oil and gas layers. As my country continues to increase its efforts in the exploitation of unconventional oil and natural gas resources, the demand for high-grade steel, high-strength, and high-toughness oil casing in the exploration and development of unconventional oil and gas reservoirs is increasing.

[0003] During the machining of high-grade steel tubing and casing, the hardness of the material exacerbates insert wear. Inadequate cooling of the insert during the cutting process directly impacts both insert life and product quality. Furthermore, when machining tubing and casing on CNC lathes, the cutting fluid outlet is oriented parallel to the tube axis. This results in a large amount of coolant covering a long section of the finished tubing surface from the tube end, causing corrosion and impacting product performance.

[0004] In view of the above-mentioned related technologies, the inventor believes that it is necessary to adjust the direction of the coolant water channel of the CNC thread processing lathe to avoid performance failure of the oil casing products due to processing quality problems. Utility Model Content

[0005] In order to improve the blade cooling effect, increase the service life of the processing blade, reduce the frequency of tool change, improve the oil casing processing efficiency, reduce the coverage area of the coolant on the pipe body, avoid the corrosion of the pipe body due to the coolant, improve the coolant recycling rate, and reduce the oil casing processing cost, the present application provides an oil casing processing coolant water circuit converter.

[0006] This application provides a coolant water channel converter for oil casing machining, which adopts the following technical solution:

[0007] A coolant water channel converter for oil casing machining includes a converter body, a coolant inlet hole is formed on the converter body, a coolant outlet hole is formed on the converter body vertically relative to the position of the cutting tool, a coolant water channel is formed between the converter body relative to the coolant inlet hole and the coolant outlet hole, one end of the coolant water channel is connected to the coolant inlet hole, and the other end of the coolant water channel is connected to the coolant outlet hole.

[0008] By adopting the above technical solution, the coolant water circuit converter is connected to the turret of the CNC machining lathe. When the oil casing is threaded, the coolant flows from the turret into the coolant water circuit converter inlet hole under the action of the high-pressure water pump, flows through the coolant water circuit of the coolant water circuit converter to the coolant outlet hole, and is sprayed out from the coolant outlet hole to directly lubricate and cool the tip of the blade, thereby improving the service life of the blade, reducing the coolant coverage area of the oil casing body, improving the coolant circulation utilization rate, and reducing the oil casing processing cost.

[0009] Optionally, a side wall of the converter body is provided with a fixed connection hole, and the fixed connection hole is used to connect the converter body to the lathe turret via a fixing piece.

[0010] Optionally, a plurality of the fixed connection holes are provided on the converter body.

[0011] Optionally, a guide groove is provided on the converter body relative to the coolant outlet hole, and a guide surface is formed on the converter body relative to the guide groove, and the guide surface is inclined along the height direction from top to bottom toward the side away from the coolant outlet hole.

[0012] By adopting the above technical solution, the iron chips generated by the blade when processing the oil casing body are spiral-shaped. As the cutting continues, the iron chips move along the inclined direction of the iron chip guide surface. Since the surface of the iron chip guide surface is smooth and inclined downward, the iron chips encounter less resistance during the discharge process, so that the iron chips are discharged directly from the guide groove, which can reduce the possibility of iron chips entangled with the blade, thereby achieving the effect of improving the processing quality of the thread surface of the oil casing body and reducing damage to the blade.

[0013] Optionally, the included angle formed by the guide surface and the rake face of the cutting blade is 45°-60°.

[0014] Optionally, the distance between the top end of the coolant outlet hole and the rake face of the cutting tool is 5-10 mm.

[0015] Optionally, the outlet direction of the coolant outlet hole is perpendicular to the axial direction of the oil casing body.

[0016] Optionally, the axis direction of the coolant outlet hole is perpendicular to the machining blade.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] 1. The coolant water channel converter has a special structural design and an overall thickness that is moderate. This can prevent the coolant water channel converter from being too thick, which may cause the blade to cut the oil casing and cause the iron chips to be unable to be discharged, and the coolant water channel converter to scratch the processing interface. In addition, it can also prevent the coolant water channel converter from being too thin, which may cause the coolant output to be small and fail to achieve sufficient cooling effect.

[0019] 2. Through the special coolant outlet hole structure design of the coolant water channel converter, the coolant outlet hole of the coolant water channel converter is perpendicular to the processing blade and close to the processing blade, so that the coolant can be directly poured onto the tip of the thread blade, thereby improving the cooling effect of the blade during processing, increasing the service life of the processing blade, and reducing the frequency of tool changes.

[0020] 3. The special chip guide groove structure design of the coolant water circuit converter makes it difficult for the chips generated when the blade cuts the oil casing body to entangle the blade, reducing blade damage. The chips are directly discharged from the chip guide groove, away from the thread surface of the oil casing end, preventing the thread surface from being scratched by the chips and improving the processing quality of the thread surface of the oil casing end.

[0021] 4. Through the special coolant outlet hole structure design of the coolant water circuit converter, the direction of the coolant outlet hole is perpendicular to the axis direction of the oil casing body, which reduces the coolant coverage area on the oil casing body during processing, reduces the workload of subsequent oil casing body spraying operations, and increases the corrosion resistance of the oil casing body.

[0022] 5. Through the special structural design of the coolant water circuit converter, the amount of coolant remaining on the oil casing after processing is reduced, the coolant reflux storage is realized, the coolant recycling rate is improved, and the production cost of oil casing processing is reduced.

[0027] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0029] The following is combined with Figure 1-3 This application is described in further detail.

[0030] The embodiment of the present application discloses a water circuit converter for coolant in oil casing machining. Figure 1 、 Figure 2 A coolant water channel converter for oil casing machining includes a converter body 1 having a rectangular structure. A horizontal avoidance groove 2 is formed on the side wall of the converter body 1. The avoidance groove 2 completely penetrates the side wall of the converter body 1. The avoidance groove 2 forms a horizontal liquid outlet surface 11 in the converter body 1.

[0031] A fixing hole 3 is horizontally defined at the lower portion of the vertical sidewall of the converter body 1. This hole 3 completely penetrates the converter body 1. Two fixing holes 3 are provided, with the line connecting the two fixing holes 3 running horizontally. The converter body 1 is secured to the lathe turret via bolts through these two fixing holes 3, securing the converter body 1 to the lathe turret.

[0032] A coolant inlet hole 4 is horizontally opened on the vertical side wall of the converter body 1. The position of the coolant inlet hole 4 is opposite to the position of the turret coolant outlet, so that the coolant from the turret coolant outlet is injected into the coolant inlet hole 4.

[0033] A coolant outlet hole 5 is vertically defined on the outlet surface 11 of the converter body 1. The depth of the outlet hole 5 is the same as that of the coolant inlet hole 4, which is positioned opposite the machining blade. The distance between the outlet surface 11 of the converter body 1 and the rake face of the machining blade is 5-10 mm. The axis of the coolant outlet hole 5 in the converter body 1 is perpendicular to the machining blade, and the outlet direction of the outlet hole in the converter body 1 is perpendicular to the axis of the oil casing.

[0034] Reference Figure 2 、 Figure 3A coolant channel 6 is horizontally disposed between the coolant inlet hole 4 and the coolant outlet hole 5. One end of the coolant channel 6 is in relative communication with the coolant inlet hole 4, and the other end of the coolant channel 6 is in relative communication with the coolant outlet hole 5. Coolant is thus drawn from the turret into the coolant inlet hole 4 by a high-pressure water pump, and is then guided by the coolant channel 6 and discharged from the coolant outlet hole 5, where it is directly poured onto the cutting edge of the machining blade, thereby cooling the blade and reducing the temperature of the blade and the workpiece being machined. This results in an increase in the service life of the blade and a reduction in the amount of coolant remaining in the tube.

[0035] Reference Figure 1 、 Figure 3 A guide groove 7 is provided on the liquid outlet surface 11 of the converter body 1. The guide groove 7 forms a guide surface 71 on the side wall of the converter body 1. One end of the guide surface 71 is located on the liquid outlet surface 11, and the other end of the guide surface 71 is located on the vertical side wall of the converter body 1 away from the coolant inlet hole 4. The guide surface 71 is tilted, and the guide surface 71 is tilted toward the side away from the coolant outlet hole 5 along the height direction from top to bottom. The angle formed by the guide surface 71 and the cutting tool rake face is 45°-60°. When the blade processes the oil casing, the iron chips are discharged with less obstruction and are discharged directly from the iron chip guide groove 7, which can reduce the possibility of iron chips accumulating in the iron chip guide groove 7 and reduce the phenomenon of iron chips wrapping around the blade, thereby achieving the effect of reducing damage to the blade and improving the surface quality of the thread at the end of the oil casing.
