Description

Technical Field

[0001] This utility model belongs to the field of steel pipe processing technology, specifically relating to an automatic loading and unloading device for a threaded pipe machine. Background Technology

[0002] Threaded pipes are widely used in petroleum, natural gas, construction, machinery manufacturing and fluid transportation. In the production process of threaded pipes, the ends of the pipes are usually machined, rolled or tapped by a threading machine to form the required external or internal thread structure. This process places high demands on the positioning accuracy, clamping stability and loading and unloading efficiency of the pipes.

[0003] Currently, most pipe threading machines still rely on manual or semi-automatic loading and unloading operations. Operators must manually feed the pipes to be processed into the machine and remove the finished product after processing. This method is not only labor-intensive and inefficient, but also poses safety hazards, especially when processing thicker, longer, or high-temperature pipes. Furthermore, manual loading and unloading makes it difficult to guarantee the repeatability of pipe positioning accuracy, easily leading to unstable threading quality and affecting product consistency. To improve automation, some manufacturers have attempted to introduce robotic arms, conveyor belts, or simple pneumatic or hydraulic feeding devices to achieve automatic loading and unloading. However, the results are generally unsatisfactory, mainly due to insufficient positioning accuracy and poor applicability, failing to meet the needs of various pipe diameters.

[0004] In view of the above, it is necessary to design an automatic loading and unloading device for threaded pipe machines that is low in cost, simple in structure, and can effectively improve positioning accuracy and expand its application range. To this end, the applicant has made beneficial designs, and the technical solution described below arose from this background. Utility Model Content

[0005] The purpose of this invention is to provide an automatic loading and unloading device for a threaded pipe machine, which helps to improve the feeding, receiving, and unloading structure of steel pipes, enabling the steel pipes to enter the working position accurately and smoothly and to be easily removed after processing. This is beneficial to improving the processing efficiency and finished product qualification rate of the threaded pipe machine.

[0006] The present invention accomplishes its objective as follows: an automatic loading and unloading device for a threaded pipe machine includes a frame extending in a front-to-back direction, a set of spaced-apart support components located above the frame, a set of receiving plates located above the frame and between adjacent support components, a set of pusher frames located above the frame and on the front side of the corresponding receiving plates, a pipe storage rack located on the right side of the frame, and a set of pipe branch components located below the storage rack and corresponding to the receiving plates. The receiving plates and corresponding pipe branch components are interconnected and move vertically, while the pusher frames move horizontally. During the upward movement, the receiving plates and corresponding pipe branch components separate a steel pipe from the storage rack via the pipe branch components, causing the steel pipe to roll onto the receiving plate. During the downward movement, the receiving plates and corresponding pipe branch components smoothly place the steel pipe onto the support components via the receiving plate. After the steel pipe is processed, the pusher frames push the steel pipe off the support components from the frame.

[0007] In one specific embodiment of this utility model, the frame is assembled and welded from I-beams.

[0008] In another specific embodiment of this utility model, the frame has a feeding rack on the side away from the storage rack, and the feeding rack has an upward-facing feeding rack cavity, into which the processed steel pipe falls.

[0009] In another specific embodiment of this utility model, a lifting bracket is fixed on one side of the frame at a position corresponding to the receiving plate and the branch pipe fitting. A lifting hydraulic cylinder is installed on the lifting bracket. The lifting hydraulic cylinder forms a pair of lifting hydraulic cylinder columns upward. A synchronous lifting plate is fixed above the lifting hydraulic cylinder columns. A branch pipe fitting connecting column is formed upward on the synchronous lifting plate at a position corresponding to the branch pipe fitting. The branch pipe fitting connecting column is connected and fixed to the lower end of the branch pipe fitting by fasteners. One end of the synchronous lifting plate extends towards the receiving plate and is fixed with a receiving plate connecting seat. A receiving plate column is fixed upward on the receiving plate connecting seat. The upper end of the receiving plate column passes through the frame upward and is fixedly connected to the receiving plate.

[0010] In another specific embodiment of this utility model, a pusher bracket is fixed on one side of the frame at a position corresponding to the pusher frame. A pusher hydraulic cylinder is installed on the pusher bracket. The pusher hydraulic cylinder forms a pusher hydraulic cylinder column obliquely upward toward one side of the frame. The end of the pusher hydraulic cylinder column is fixedly connected to the pusher frame.

[0011] In another specific embodiment of this utility model, a pressure roller is respectively arranged above the frame and next to the support assembly. The pressure roller is cantilevered and swings on the frame via a pressure roller shaft, which is rotatably supported on the frame.

[0012] In a further specific embodiment of the present invention, the hosting assembly includes a pair of hosting rollers and a pair of hosting roller seats, wherein the hosting rollers are rotatably supported between the pair of hosting roller seats at left and right intervals.

[0013] In a further specific embodiment of this utility model, the receiving plate is provided with a receiving cavity facing upwards.

[0014] In another specific embodiment of this utility model, one end of the pusher frame is provided with a pusher opening facing obliquely upward, and the other end of the pusher frame is provided with a pusher frame fixing seat.

[0015] In another specific embodiment of this utility model, a branch pipe fitting is formed above the branch pipe fitting, and the storage rack is formed with openings at positions corresponding to the branch pipe fitting for the branch pipe fitting to pass through upward. A set of storage rack blocks are arranged at intervals along the front-back direction at the upper left end of the storage rack. During the upward process of the branch pipe fitting, the leftmost steel pipe is pushed against the storage rack block, thereby freeing the steel pipe from the constraint of the storage rack and rolling it down the branch pipe fitting's inclined surface into the receiving cavity of the receiving plate.

[0016] The present invention has the following advantages due to the above-mentioned structure: First, the structure in which the receiving plate and the pipe fitting move synchronously to complete the pipe feeding and receiving actions, and the receiving plate connects the steel pipe to the support assembly, enables the steel pipe to enter the working position of the threading machine accurately and smoothly, effectively improving the processing efficiency and finished product qualification rate of the threading machine; Second, the structure in which the pusher frame pushes the steel pipe away from the working position enables the steel pipe to stably leave the working position of the threading machine and fall into the unloading rack cavity of the unloading rack, thereby further improving the processing efficiency of the threading machine.

The aforementioned receiving plates 3 and corresponding... The branch pipe components 7 are interconnected and move vertically. The aforementioned pusher frame 4 moves horizontally. During the upward movement, the aforementioned receiving plate 3 and the corresponding branch pipe component 7 separate one of the steel pipes 9 from the storage rack 10 through the branch pipe component 7 and make the steel pipe 9 roll into the receiving plate 3. During the downward movement, the aforementioned receiving plate 3 and the corresponding branch pipe component 7 place the steel pipe 9 smoothly on the hosting component 2 through the receiving plate 3. After the steel pipe 9 has been processed, the aforementioned pusher frame 4 pushes the steel pipe 9 on the hosting component 2 away from the aforementioned frame 1.

[0022] Furthermore, the aforementioned frame 1 is assembled and welded from I-beams. The aforementioned frame 1 has a discharge rack 13 on the side away from the storage rack 10, and the aforementioned discharge rack 13 has a discharge rack cavity 131 formed upwards, into which the processed steel pipes fall.

[0023] A lifting bracket 12 is fixed on one side of the aforementioned frame 1 at a position corresponding to the receiving plate 3 and the branch pipe 7. A lifting hydraulic cylinder 8 is installed on the aforementioned lifting bracket 12. The aforementioned lifting hydraulic cylinder 8 forms a pair of lifting hydraulic cylinder columns 81 upwards. A synchronous lifting plate 82 is fixed above the aforementioned lifting hydraulic cylinder columns 81. The aforementioned synchronous lifting plate 82 forms a branch pipe connecting column 83 upwards at a position corresponding to the branch pipe 7. The aforementioned branch pipe connecting column 83 is connected and fixed to the lower end of the branch pipe 7 by fasteners. One end of the aforementioned synchronous lifting plate 82 extends toward the receiving plate 3 and is fixed with a receiving plate connecting seat 84. The aforementioned receiving plate connecting seat 84 is fixed upwards with a receiving plate column 85. The upper end of the aforementioned receiving plate column 85 passes upwards through the frame 1 and is fixedly connected to the receiving plate 3. A pusher bracket 11 is fixed on one side of the aforementioned frame 1 at a position corresponding to the pusher frame 4. A pusher hydraulic cylinder 6 is installed on the aforementioned pusher bracket 11. The aforementioned pusher hydraulic cylinder 6 forms a pusher hydraulic cylinder column 61 obliquely upward toward the side of the frame 1. The end of the aforementioned pusher hydraulic cylinder column 61 is fixedly connected to the pusher frame 4.

[0024] Please see Figure 1 and combined Figure 2 A pressure roller 5 is provided above the aforementioned frame 1 and next to the hosting component 2. The aforementioned pressure roller 5 is cantilevered and swings on the frame 1 via a pressure roller shaft 51, which is rotatably supported on the frame 1.

[0025] Please see Figure 2 The aforementioned hosting components 2 each include a pair of hosting rollers 21 and a pair of hosting roller seats 22, with the aforementioned hosting rollers 21 being rotatably supported on the left and right sides of the pair of hosting roller seats 22.

[0026] Please see Figure 1 and Figure 3 The aforementioned receiving plate 3 has an upward-facing receiving cavity 31. One end of the aforementioned pusher 4 has a pusher opening 41 facing obliquely upward, and the other end of the aforementioned pusher 4 has a pusher fixing seat 42, specifically, the aforementioned pusher fixing seat 42 is fixedly connected to the pusher hydraulic cylinder column 61. Above the aforementioned branch pipe 7, there is a branch pipe inclined surface 71. The aforementioned storage pipe rack 10 has openings at positions corresponding to the branch pipe 7 for the branch pipe 7 to pass through upward. At the upper left end of the aforementioned storage pipe rack 10, a set of storage pipe rack blocks 101 are spaced apart along the front-back direction. During the upward movement of the aforementioned branch pipe 7, the leftmost steel pipe 9 is pushed against the storage pipe rack block 101, thereby causing the steel pipe 9 to break free from the constraint of the storage pipe rack 10 and roll down through the branch pipe inclined surface 71 into the receiving cavity 31 of the receiving plate 3.

[0027] Please see Figures 1-5 ,like Figure 1As shown, the steel pipes 9 are evenly arranged on the aforementioned storage rack 10, and the storage rack stops 101 prevent the steel pipes 9 from rolling off the storage rack 10. When feeding is required, as... Figure 3 As shown, the aforementioned lifting hydraulic cylinder 8 operates, synchronously pushing the receiving plate 3 and the branch pipe component 7 upwards via the lifting hydraulic cylinder column 81 and the synchronous lifting plate 82. The aforementioned branch pipe component 7 pushes the steel pipe 9 located on the leftmost side of the storage rack 10 above the storage rack stop 101 via the branch pipe component inclined surface 71. At this time, the steel pipe 9 continues to roll to the left under the action of the aforementioned branch pipe component inclined surface 71 and falls into the receiving cavity 31 of the receiving plate 3 that has risen to the side. Then, the lifting hydraulic cylinder column 81 and the synchronous lifting plate 82 of the aforementioned lifting hydraulic cylinder 8 descend. At this time, the aforementioned receiving plate 3 and the branch pipe component 7 descend synchronously. When the aforementioned receiving plate 3 descends, it places the steel pipe 9 smoothly on the support assembly 2. Specifically, the steel pipe 9 is supported between the two aforementioned support rollers 21, thereby completing the positioning of the steel pipe 9. Then, the aforementioned pressure roller shaft 51 is driven to rotate, so that the pressure roller 51... Figure 4 The steel pipe 9, as shown, is pressed onto the support assembly 2. At this point, the steel pipe 9 is positioned and processed. After processing is complete, the aforementioned pressure roller shaft 51 rotates in the reverse direction, causing the pressure roller 5 to disengage from the steel pipe 9, and finally... Figure 5 As shown, when the aforementioned pusher hydraulic cylinder 6 is working, the pusher hydraulic cylinder column 61 pushes the pusher frame 4 to move to the upper left. During the displacement process, the pusher frame 4 pushes the steel pipe 9 away from the aforementioned support assembly 2 through the pusher port 41 on it, and causes the steel pipe 9 to roll into the unloading frame cavity 131 of the aforementioned unloading frame 13, thereby completing the entire loading and unloading process.

[0028] In summary, the technical solution provided by this utility model makes up for the shortcomings of the prior art, successfully completes the utility model task, and faithfully realizes the technical effects described by the applicant in the above technical effect column.
