Technical Field

[0001] The utility model relates to the technical field of tube blanks, in particular to a special tube blank for oil casing coupling materials. Background Technique

[0002] A tube blank refers to the blank used for producing steel pipes. Usually, high-quality or alloy solid round steel is used as the tube blank. For some tube production methods, ingots, continuous casting billets, forged billets, rolled square billets, and centrifugally cast hollow billets are also used as the blanks for making tubes. The tube blanks used for producing steel pipes can be classified according to smelting and casting methods, chemical compositions, forming methods, and service conditions, etc.

[0003] In the prior art, after the tube blank is cast and formed, the tube blank needs to be demolded. The traditional demolding method is to invert the mold on the bottom surface and then strike the plate surface of the mold to vibrate out the tube blank. However, due to the limited striking area of the leather hammer, it is necessary to strike the mold repeatedly, which is time-consuming and laborious. Therefore, we propose a special tube blank for oil casing coupling materials to solve the problems raised above. Content of the Utility Model

[0021] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0022] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0023] Embodiment 1, as Figures 1 - 4 shown, a special tube blank for oil casing coupling material includes an overall structure 1 and a support structure 2. The support structure 2 is located at the front and rear positions on both sides of the bottom of the overall structure 1; the overall structure 1 includes a bottom plate 101. The first telescopic rod 102 is fixedly installed at the front and rear positions on one side of the top of the bottom plate 101. The extending end of the first telescopic rod 102 is fixedly connected to the first connecting plate 103. The rotating shaft 105 is rotatably connected to the outer surface of the other side of the first connecting plate 103 near the center. The second telescopic rod 107 is fixedly installed at the front and rear positions on the other side of the top of the bottom plate 101. The extending end of the second telescopic rod 107 is fixedly connected to the second connecting plate 108. The rotating disk 113 is rotatably connected to the outer surface of one side of the second connecting plate 108 near the center. The tube blank mold 104 is fixedly connected to the opposite sides of the rotating shaft 105 and the rotating disk 113.

[0024] The effect achieved by the entire Embodiment 1 is that when the first telescopic rod 102 and the second telescopic rod 107 extend or retract, they will drive the first connecting plate 103 and the second connecting plate 108 to move up and down together. When the first connecting plate 103 and the second connecting plate 108 can move, they will drive the tube blank mold 104 to move together. Eventually, the tube blank mold 104 can be raised to a certain position, enabling the subsequent flipping operation to proceed normally and avoiding interference.

[0025] Embodiment 2 is as Figures 1 - 4 shown. On one side outer surface of the first connecting plate 103 at the position of the rotating shaft 105, a servo motor 106 is fixedly installed. One end of the rotating shaft 105 penetrates the surface of the first connecting plate 103 and is fixedly connected to the driving end of the servo motor 106. The other end of the rotating shaft 105 is fixedly connected to the outer surface of the tube blank mold 104. At the top and bottom of the other side outer surface of the second connecting plate 108, insertion rods 115 are arranged through. On one side outer surface of the insertion rods 115, a pull rod 114 is fixedly connected. On the outer surface of the rotating disc 113 at the position of the insertion rods 115, circular holes 116 are opened. The inner wall of the circular holes 116 is fixedly connected to the outer surface of the insertion rods 115. On both sides of the front and back positions of the inner bottom of the tube blank mold 104, third telescopic rods 109 are fixedly installed. The extending end of the third telescopic rod 109 is fixedly connected to a movable circular plate 111. On the top of the movable circular plate 111, a number of uniformly distributed knocking heads 112 are fixedly connected. Near the center of the inner surface of the tube blank mold 104, a partition plate 117 is fixedly connected. A compression spring 110 is sleeved on the outer surface of the third telescopic rod 109. One end of the compression spring 110 is fixedly connected to the outer surface of the third telescopic rod 109, and the other end of the compression spring 110 is fixedly connected to the bottom surface of the movable circular plate 111. The top surface of the knocking head 112 is slidably connected to the bottom surface of the partition plate 117. The support structure 2 includes a round rod 201. The bottom end face of the round rod 201 is fixedly connected to a suction cup 202. The top end face of the round rod 201 is fixedly connected to the bottom surface of the bottom plate 101.

[0026] The effect achieved by the entire Embodiment 2 is that as Figure 1 、 Figure 2 and Figure 4 shown, since the insertion rods 115 penetrate the rotating disc 113, when the two insertion rods 115 are inserted into the corresponding circular holes 116 through the pull rod 114, the rotation of the rotating disc 113 can be limited, and indirectly, the tube blank mold 104 can also be limited to avoid subsequent swinging. The knocking head 112 uses the force of the extension of the third telescopic rod 109 and the expansion force of the compression spring 110 to strike the partition plate 117 forcefully back and forth, accelerating the speed of the tube blank falling off.

[0027] Working principle: After the billet body in the billet mold 104 is cast and formed, the first telescopic rod 102 and the second telescopic rod 107 start to extend together, driving the first connecting plate 103 and the second connecting plate 108 to rise. After rising to an appropriate position, the servo motor 106 starts to operate, enabling the rotating shaft 105 to rotate, and then driving the billet mold 104 and the rotating disc 113 to rotate, so that the billet mold 104 can be flipped 180 degrees. After the flipping is completed, the user inserts the two insertion rods 115 into the corresponding round holes 116 through the pull rod 114 to limit the rotating disc 113. Then the third telescopic rod 109 starts to extend and retract back and forth, enabling the knocking head 112 and the movable circular plate 111 to move up and down slightly, so that the knocking head 112 can normally knock on the partition plate 117, and then the billet body in the billet mold 104 can be shaken off.

[0028] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
