Description

Technical Field

[0001] This application relates to the technical field of fixing fixtures, and in particular to a straightening and fixing fixture for seamless steel pipes. Background Technology

[0002] Seamless steel pipes have a hollow cross-section and are widely used as pipelines for transporting fluids, such as oil, natural gas, coal gas, water, and certain solid materials. The processing of seamless steel pipes is an important part of the steel pipe production process. Its purpose is to eliminate shape defects such as bending and twisting that occur during rolling, cooling, and transportation, and to ensure that the steel pipes have good straightness and flatness.

[0003] The existing announcement number is CN218079738U, entitled "A Seamless Steel Pipe Straightening and Fixing Fixture," which includes a working frame. A baffle strip is fixedly installed on the top of the working frame. A cylinder is bolted to the front of the inner wall of the working frame. A moving plate is fixedly installed at the rear end of the cylinder. Connecting blocks are fixedly installed on both sides of the top of the moving plate. The tops of the two connecting blocks penetrate the top of the working frame and are bolted to a pressing plate. Grooves are opened on both sides of the back of the pressing plate. When the cylinder is activated, it pushes the moving plate to slide on the surface of the sliding rod. The moving plate drives the connecting blocks to push the pressing plate. The pressing plate and the baffle strip clamp the steel pipe horizontally. When the adjusting disc drives the adjusting rod to rotate, the lower pressing plate presses the steel pipe vertically. The curved pipe is heated, and the heat is dissipated through the heating chamber and the heat-conducting plate to heat the steel pipe. When the hydraulic telescopic rod is activated, it pushes the straightening plate to straighten the curved part of the steel pipe.

[0004] Regarding the aforementioned technologies, the inventors discovered that when the steel pipe is straightened, it is straightened by clamping the steel pipe with a lower pressure plate and a moving plate and a pushing plate. However, when the moving plate and the pushing plate clamp the steel pipe, the friction coefficient increases, and the steel pipe cannot be moved laterally during straightening. This results in the steel pipe being unable to move during straightening, increasing the number of steps involved in straightening and disassembling the steel pipe, which affects the continuity of the transportation of the straightened steel pipe. Utility Model Content

[0005] In order to overcome the problem that the friction coefficient increases when the existing moving plate and pressing plate clamp the steel pipe, making it impossible to move the steel pipe laterally during straightening, which leads to the steel pipe being unable to move during straightening, and increasing the number of steps for straightening and disassembling the steel pipe section by section, thus affecting the continuity of steel pipe straightening transportation, this application provides a seamless steel pipe straightening and fixing clamp.

[0006] The seamless steel pipe straightening and fixing clamp provided in this application adopts the following technical solution:

[0007] A seamless steel pipe straightening and fixing fixture includes a base, a conveying component, a first straightening component, and a second straightening component. The conveying component is vertically mounted at both ends of the top surface of the base, and the second straightening component is vertically mounted in the middle of the top surface of the base. Two first straightening components are symmetrically arranged and positioned between the second straightening component and the conveying component. Each first straightening component includes a hole frame, which is vertically fixed to the top surface of the base. Rod seats are horizontally slidably assembled on both sides of the hole frame, and straightening wheels are vertically rotatably connected to the rod seats on both sides of the hole frame. The second straightening component includes a straightening slide frame, which is vertically fixed to the middle of the top surface of the base. A top wheel is horizontally fixed to the lower inner side of the straightening slide frame, and a sliding plate is vertically slidably assembled to the upper inner side of the straightening slide frame. A guide rod is horizontally rotatably connected to the bottom surface of the sliding plate.

[0008] By adopting the above technical solution, when straightening steel pipes, the steel pipe is fed from one end of the machine base into the conveyor at the other end. The steel pipe is then conveyed into the first and second straightening components. In the first straightening component, the steel pipe is horizontally slid by the rods on both sides of the frame, causing the straightening wheels at the ends of the rods to straighten the steel pipe horizontally. Then, the steel pipe enters the second straightening component, where the top wheel and guide rod in the straightening slide frame are used to straighten the steel pipe vertically. During the straightening process, the steel pipe is powered by the conveyor, which moves it into the first and second straightening components for straightening. The horizontal pushing motion during straightening allows for easy straightening of the steel pipe, avoiding the problem of increasing the number of steps involved in straightening and disassembling the steel pipe section by section, and improving the continuity of steel pipe straightening transportation.

[0009] Optionally, a first spring is horizontally fixed on both vertical end faces of the hole frame, and the other end of the first spring is fixed on the rod seat.

[0010] By adopting the above technical solution, in order to ensure that the steel pipe is horizontally slid by the rod seats on both sides of the hole frame in the first straightening member, and that the straightening wheel at the end of the rod seat is driven to straighten the steel pipe in the horizontal direction, the deformation force generated by the first spring is used to push the straightening wheel against the straightened steel pipe to maintain the horizontal pressure and straightening.

[0011] Optionally, a screw hole is provided through the vertical thread on the top surface of the straightening slide frame, and an adjusting screw is assembled through the screw hole, with the bottom end of the adjusting screw rotatably connected to the top surface of the slide plate.

[0012] By adopting the above technical solution, based on the distance between the top wheel and the guide rod of the vertical straightening steel pipe, the adjusting screw in the screw hole at the top of the straightening slide frame is manually rotated. The adjusting screw pushes the slide plate to slide vertically down on the straightening slide frame, adjusting the distance between the top wheel and the guide rod, which is suitable for adjusting the pressure requirements of vertical straightening of steel pipe.

[0013] Optionally, two swivel blocks are symmetrically and vertically fixed on the bottom surface of the skateboard, and a guide rod is horizontally rotatably connected between the two swivel blocks.

[0014] By adopting the above technical solution, two rotating blocks fixed on the bottom surface of the slide plate are used to rotate and connect the guide rod. The rotating guide rod is used to adjust the vertical straightening and pressure requirements of the steel pipe.

[0015] Optionally, guide blocks are symmetrically and horizontally slidably assembled on both sides of the guide rod, and a second spring is horizontally sleeved on both sides of the guide rod, with the two ends of the second spring fixed to the guide block and the end face of the guide rod, respectively.

[0016] By adopting the above technical solution, guide blocks are horizontally slidably assembled on both sides of the guide rod. Under the action of the deformation force of the second spring, the deformation force of the second spring pushes the guide blocks to slide on the guide rod, thereby driving the guide blocks on both sides of the guide rod to meet the clamping and pressing requirements of the outer diameter of the steel pipe.

[0017] Optionally, the conveying component includes a conveyor frame, which is vertically fixed at both ends of the machine base, and a support wheel is horizontally rotatably connected to the lower side of the conveyor frame. A support motor is horizontally fixed at one end of the conveyor frame, and the output end of the support motor is fixed at one end of the support wheel.

[0018] By adopting the above technical solution, when the steel pipe is being straightened during transport, the support motor on the conveyor frame is started to drive the support wheel to rotate, which in turn drives the clamped steel pipe to move laterally on the conveyor frame, thereby driving the steel pipe to move laterally for continuous straightening.

[0019] Optionally, a top rotating frame is vertically slidably assembled on the upper side of the conveyor frame, and a pressure roller is horizontally rotatably connected to the top rotating frame.

[0020] By adopting the above technical solution, a pressure roller is horizontally rotatably connected to the top rotating frame on the upper side of the conveyor frame. The pressure roller is used to press down on the conveyor guide steel pipe to straighten it.

[0021] Optionally, a downward pressing screw is installed through a vertical thread on the top surface of the conveyor frame, and the bottom end of the downward pressing screw is rotatably connected to the top surface of the top rotating frame.

[0022] By adopting the above technical solution, the downward screw on the rotating conveyor frame is used to push the top rotating frame to move vertically downward, which in turn drives the pressure roller to move downward to press the steel pipe to be conveyed and moved on the top roller.

[0023] In summary, this application includes at least one of the following beneficial technical effects: When straightening steel pipes, the steel pipe is fed from one end of the machine base into the conveyor at the other end of the machine base. The steel pipe is conveyed by the conveyor and driven into the first straightening piece and the second straightening piece. In the first straightening piece, the steel pipe is horizontally slid by the rod seats on both sides of the hole frame, which drives the straightening wheel at the end of the rod seat to straighten the steel pipe in the horizontal direction. Then, the steel pipe enters the second straightening piece, where the top wheel and guide rod in the straightening slide frame are used to straighten the steel pipe in the vertical direction. When straightening the steel pipe, the steel pipe is powered by the conveyor and driven into the first and second straightening pieces for straightening. The steel pipe is pushed and moved laterally during straightening, which allows for the straightening of the steel pipe. The movement of the steel pipe during straightening avoids the problem of increasing the steps of straightening and disassembling the steel pipe section by section, and improves the continuity of the transportation of the straightened steel pipe.

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] This application discloses a straightening and fixing fixture for seamless steel pipes. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4A seamless steel pipe straightening and fixing fixture includes a base 1, a conveyor 2, a first straightening component 3, and a second straightening component 4. The conveyor 2 is vertically installed at both ends of the top surface of the base 1, and the second straightening component 4 is vertically installed in the middle of the top surface of the base 1. Two first straightening components 3 are symmetrically arranged and are positioned between the second straightening component 4 and the conveyor 2. The first straightening component 3 includes a hole frame 31, which is vertically fixed to the top surface of the base 1. Rod seats 32 are horizontally slidably assembled on both sides of the hole frame 31. Straightening wheels 34 are vertically rotatably connected to the rod seats 32 on both sides of the hole frame 31. The second straightening component 4 includes a straightening slide frame 41, which is vertically fixed to the middle of the top surface of the base 1. A top wheel 42 is horizontally fixed to the lower side of the straightening slide frame 41. A slide plate 44 is vertically slidably assembled to the upper side of the straightening slide frame 41, and a guide rod 47 is horizontally rotatably connected to the bottom surface of the slide plate 44.

[0032] By adopting the above technical solution, when straightening steel pipes that need to be straightened, the steel pipe is fed from one end of the machine base 1 into the conveyor 2 at one end of the machine base 1. The steel pipe is conveyed by the conveyor 2 into the first straightening piece 3 and the second straightening piece 4. In the first straightening piece 3, the steel pipe is horizontally slid by the rod seats 32 on both sides of the hole frame 31, which drives the straightening wheel 34 at the end of the rod seat 32 to straighten the steel pipe in the horizontal direction. Then the steel pipe enters the second straightening piece 4, where the top wheel 42 and guide rod 47 in the straightening slide frame 41 are used to straighten the steel pipe in the vertical direction. When straightening the steel pipe, the steel pipe is powered by the conveyor 2, which conveys the steel pipe into the first straightening piece 3 and the second straightening piece 4 for straightening. The steel pipe is pushed and moved laterally during straightening, which can move the steel pipe for straightening. The steel pipe moves during straightening, avoiding the problem of increasing the number of steps of straightening and disassembling the steel pipe section by section, and improving the continuity of steel pipe straightening transportation.

[0033] Reference Figure 3 Both sides of the hole frame 31 are horizontally fixed with first springs 33, and the other end of the first springs 33 is fixed to the rod seat 32. In order to ensure that the steel pipe is horizontally slid by the rod seats 32 on both sides of the hole frame 31 in the first straightening member 3, and to drive the straightening wheel 34 at the end of the rod seat 32 to straighten the steel pipe in the horizontal direction, the deformation force generated by the first spring 33 pushes the straightening wheel 34 to press against the straightened steel pipe to maintain the horizontal pressing and straightening.

[0034] Reference Figure 4A vertical threaded hole 43 is provided on the top surface of the straightening slide frame 41, and an adjusting screw 45 is installed through the screw hole 43. The bottom end of the adjusting screw 45 is rotatably connected to the top surface of the slide plate 44. According to the distance between the top wheel 42 and the guide rod 47 for vertical straightening of the steel pipe, the adjusting screw 45 in the top screw hole 43 of the straightening slide frame 41 is manually rotated. The adjusting screw 45 pushes the slide plate 44 to slide vertically down on the straightening slide frame 41, adjusting the distance between the top wheel 42 and the guide rod 47 to meet the pressure adjustment requirements for vertical straightening of the steel pipe. Two rotating seats 46 are symmetrically and vertically fixed on the bottom surface of the slide plate 44, and the guide rod 47 is horizontally rotatably connected between the two rotating seats 46. In use, the two rotating seats 46 fixed on the bottom surface of the slide plate 44 are used to rotatably connect the guide rod 47, and the rotating guide rod 47 is used to adjust the pressure requirements for vertical straightening of the steel pipe. Guide blocks 49 are symmetrically and horizontally slidably assembled on both sides of the guide rod 47, and second springs 48 are horizontally sleeved on both sides of the guide rod 47, with the two ends of the second springs 48 fixed to the end faces of the guide blocks 49 and the guide rod 47, respectively. During use, the guide blocks 49 are horizontally slidably assembled on both sides of the guide rod 47. Under the deformation force of the second springs 48, the deformation force of the second springs 48 pushes the guide blocks 49 to slide on the guide rod 47, thereby enabling the guide blocks 49 on both sides of the guide rod 47 to meet the clamping and pressing requirements on both sides of the outer diameter of the steel pipe.

[0035] Reference Figure 5 The conveying component 2 includes a conveying frame 21, which is vertically fixed at both ends of the base 1. A support wheel 22 is horizontally rotatably connected to the lower side of the conveying frame 21. A support motor 23 is horizontally fixed to one end of the conveying frame 21, and the output end of the support motor 23 is fixed to one end of the support wheel 22. During use, when the steel pipe is being conveyed and straightened, the support motor 23 on the conveying frame 21 is started, driving the support wheel 22 to rotate, which in turn drives the clamped steel pipe to move laterally on the conveying frame 21, thereby driving the steel pipe to move laterally for continuous straightening. A top rotating frame 24 is vertically slidably assembled on the upper side of the conveying frame 21, and a pressure roller 26 is horizontally rotatably connected in the top rotating frame 24. The pressure roller 26 is horizontally rotatably connected to the top rotating frame 24 on the upper side of the conveying frame 21, and is used to press down on the conveying guide steel pipe for straightening. A downward pressing screw 25 is vertically threaded through the top surface of the conveyor frame 21, and the bottom end of the downward pressing screw 25 is rotatably connected to the top surface of the top rotating frame 24. When the downward pressing screw 25 on the rotating conveyor frame 21 is used, the downward pressing screw 25 pushes the top rotating frame 24 to move vertically downward, driving the pressure roller 26 to move downward to press the steel pipe to move on the top wheel 42 for conveying.

[0036] The implementation principle of a seamless steel pipe straightening and fixing fixture according to an embodiment of this application is as follows: When straightening a steel pipe to be straightened, the steel pipe is fed from one end of the machine base 1 into the conveyor 2 at one end of the machine base 1. The steel pipe is conveyed by the conveyor 2 and driven into the first straightening piece 3 and the second straightening piece 4. In the first straightening piece 3, the steel pipe is horizontally slid by the rod seats 32 on both sides of the hole frame 31, which drives the straightening wheel 34 at the end of the rod seat 32 to straighten the steel pipe in the horizontal direction. In order to ensure the clamping effect of the straightening wheel 34 at the end of the rod seat 32 being horizontally slid by the rod seats 32 on both sides of the hole frame 31 in the first straightening piece 3, the deformation force generated by the first spring 33 pushes the straightening wheel 34 to press against the straightened steel pipe to maintain the horizontal clamping effect of straightening. Then the steel pipe enters the second straightening piece 4, and the top wheel 42 and guide rod 47 of the steel pipe are used for vertical straightening. The spacing between the top wheel 42 and the guide rod 47 is adjusted by manually rotating the adjusting screw 45 in the screw hole 43 at the top of the straightening slide frame 41. The adjusting screw 45 pushes the slide plate 44 to slide vertically down on the straightening slide frame 41. The spacing between the top wheel 42 and the guide rod 47 is adjusted to meet the vertical straightening and pressure adjustment requirements of the steel pipe. The top wheel 42 and the guide rod 47 in the straightening slide frame 41 are used to straighten the steel pipe in the vertical direction. During use, guide blocks 49 are horizontally slidably assembled on both sides of the guide rod 47. Under the deformation force of the second spring 48, the deformation force of the second spring 48 pushes the guide blocks 49 to slide on the guide rod 47, and the guide blocks 49 on both sides of the guide rod 47 meet the clamping and pressure requirements on both sides of the outer diameter of the steel pipe. When straightening the steel pipe, the steel pipe is powered by the conveying component 2. The conveying steel pipe is driven into the first straightening component 3 and the second straightening component 4 for straightening. When straightening the steel pipe, it is pushed and moved laterally. The steel pipe can be moved to straighten the steel pipe. The steel pipe moves during straightening.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
